SUMMARY:Ecologische onderbouwing Beleidskader Natuur Waddenzee - publicatie
DESCRIPTION:Snel handelen in Waddenzee nodig\, voldoende motivatie voor Beleidskader Natuur Waddenzee. \nEr is overtuigend bewijs dat de natuur in de Waddenzee is verslechterd door menselijke invloeden. Verschillende rapporten tonen aan dat naast vele redenen om snel in actie te komen\, de Staat ook verplicht is te handelen. Dat schrijft de Ecologische Autoriteit in het ‘Advies ecologische onderbouwing Beleidskader Natuur Waddenzee’ aan het ministerie van Landbouw\, Visserij\, Voedselzekerheid en Natuur (LVVN). De Waddenzee is het grootste aaneengesloten intergetijdengebied ter wereld en heeft een cruciale functie voor miljoenen vogels en vissen. Maar de Waddenzeenatuur verslechtert al jarenlang en het lukt niet om het tij te keren. Daarom stelt het ministerie van LVVN een nieuw beleidskader op voor de Waddenzee. Dit beleidskader moet inzicht bieden in hoe de natuur kan herstellen en voor hoeveel menselijke activiteiten\, zoals visserij\, scheepvaart\, baggerwerkzaamheden\, recreatie\, gas-\, zout- en zandwinning en militaire oefeningen\, er in de Waddenzee plaats is zonder natuurschade te veroorzaken. Hiervoor heeft het ministerie een notitie opgesteld waarin de uitgangspunten voor het zogeheten Beleidskader Natuur Waddenzee staan. \nLinks:\nSnel handelen in Waddenzee nodig\, voldoende motivatie voor Beleidskader Natuur Waddenzee \nMinisterie: ‘Natuur van de Waddenzee staat onder grote druk’

SUMMARY:Staat van de Waddenzee 2025 - publicatie
DESCRIPTION:Hoe gaat het écht met de Waddenzee? \nDie vraag lijkt eenvoudig\, maar het antwoord is allesbehalve dat. Nederland heeft nog een paar grote aaneengesloten natuurgebieden. De Waddenzee is er één van maar staat onder druk. Het gebied vormt een dynamisch ecosysteem waarin klimaat\, natuur\, menselijke activiteit en beleid voortdurend op elkaar inwerken. Er zijn veel data over de Waddenzee beschikbaar. Die zijn nu voor het eerst samengebracht om een beter overzicht van de Waddenzee als compleet ecosysteem te krijgen. Met de publicatie van Staat van de Waddenzee 2025 kunnen de ministeries van Landbouw\, Visserij\, Voedselzekerheid\, Natuur (LVVN) en Infrastructuur en Waterstaat (IenW) een belangrijke stap zetten voor de ontwikkeling van het Beleidskader Natuur Waddenzee. Dit onderzoek is een vervolg op een eerder uitgevoerde methodologische verkenning\, en vormt een bouwsteen voor het door LVVN en IenW te ontwikkelen Beleidskader Natuur Waddenzee. \nLinks:\nDe staat van de Waddenzee tot op de bodem uitgezocht met data

SUMMARY:World Seagrass Day 2026
DESCRIPTION:In May 2022\, the United Nations General Assembly adopted A/RES/76/265 proclaiming 1 March as World Seagrass Day. \nThe resolution highlights the urgent need to raise awareness at all levels and to promote and facilitate actions for the conservation of seagrasses in order to contribute to their health and development\, bearing in mind that enhancing ecosystem services and functions is important for the achievement of the Sustainable Development Goals. Seagrasses are marine flowering plants that are found in shallow waters in many parts of the world\, from the tropics to the Arctic circle. They form extensive underwater meadows\, creating complex\, highly productive and biologically rich habitats. Covering only 0.1% of the ocean floor\, these seagrass meadows provide food and shelter to thousands of species of fish\, seahorses\, turtles\, etc. and sustain some of the world’s largest fisheries. They improve water quality by filtering\, cycling and storing nutrients and pollutants\, reducing contamination in seafood. Highly efficient carbon sinks\, they can store up to 18% of the world’s oceanic carbon\, making them a powerful nature-based solutions to tackle climate change impacts. Because they buffer ocean acidification\, they contribute to the resilience of the most vulnerable ecosystems and species\, such as coral reefs. And to the coastal populations\, they act as the first line of defense along coasts by reducing wave energy\, protecting people from the increasing risk of floods and storms. Despite its important contribution to sustainable development and climate change mitigation and adaptation\, this core component of marine biodiversity is in danger and only about a quarter of all meadows fall within marine protected areas. \nSeagrasses have been declining globally since the 1930s\, with the most recent census estimating that 7% of this key marine habitat is being lost worldwide per year. It was recently noted that 21% of seagrass species are categorized as Near Threatened\, Vulnerable and Endangered Species under the International Union for Conservation of Nature Red List of Threatened Species. The combined pressures of coastal development\, pollution\, including land-based run-off\, climate change\, dredging and unregulated fishing and boating activities are key drivers of the degradation of seagrasses and their associated ecosystems. Despite a general global trend of seagrass loss\, some areas have shown abating declines or substantial recovery of seagrasses. These recoveries can often be attributed to human interventions reducing the effect of human-caused stressors. Seagrasses are critical for life underwater\, but also provide wide-ranging benefits to people on land. Raising awareness about their importance for community well-being\, whether through food security from fish production\, improved quality of water filtered by seagrasses\, protection of coasts from erosion\, storms and floods\, or carbon sequestration and storage will drive efforts around the world to conserve\, better manage and restore these ecosystems. Ultimately\, the protection and restoration of seagrass meadows will help countries achieve multiple economic\, societal and nutritional objectives\, aligning with and supported by policies implemented at the national\, regional or global levels. For example: \n\nThe benefits from conserving and restoring seagrass meadows can also help countries achieve 26 targets and indicators associated with ten Sustainable Development Goals.\nGiven the carbon storage and sequestration capacity of seagrass ecosystems\, including them in nationally determined contributions (NDCs) can help nations achieve their targets under the Paris Agreement and the United Nations Framework Convention on Climate Change (UNFCCC).\nInclusion of seagrass ecosystems in the post-2020 global biodiversity framework and the Convention on Biological Diversity (CBD)  is also critical for protecting the integrity of marine ecosystems and biodiversity.\nRestoration of seagrasses also provides countries with opportunities to achieve commitments to be made to the United Nations Decade on Ecosystem Restoration .\n\nInclusion of seagrass management\, conservation and restoration should be a critical component of sustainable blue economy strategies in the future. Projects are already underway in various countries\, and a few have even been selected as World Restoration Flagships initiatives. Chosen as best examples of large-scale and long-term ecosystem restoration\, these projects embody the 10 restoration principles  of the United Nations Decade on Ecosystem Restoration.

SUMMARY:Abrupt Gulf Stream path changes are a precursor to a collapse of the Atlantic Meridional Overturning Circulation - publication
DESCRIPTION:The Gulf stream is moving north – and it could be an early warning sign; while this isn’t “The Day After Tomorrow\,” it’s still cause for concern. \nThe Gulf Stream\, that vital ribbon of warmth surging across the North Atlantic\, appears to be drifting northward. If this trend continues\, it could provide further evidence that the Atlantic Meridional Overturning Circulation (AMOC) is losing strength and nearing collapse as global temperatures rise. The Gulf Stream is just one piece of the AMOC\, although the two terms are often used interchangeably in casual conversation. The latter is the mother of ocean current systems in the Atlantic\, sometimes known as the “conveyor belt of the ocean\,” that transports warm\, salty water from the tropics northward towards Europe. Meanwhile\, the Gulf Stream is a western boundary current system that’s part of the upper and northward-flowing branch of this oceanic engine. Scientists are becoming increasingly concerned that warming ocean temperatures and melting ice from Greenland could be pushing the AMOC toward a catastrophic standstill. Evidence already indicates a 15 percent reduction in the circulation’s strength since the 1950s\, fueling fears of a total collapse. While this collapse wouldn’t instantly trigger the frozen apocalypse depicted in The Day After Tomorrow\, it would starve Europe of heat\, leading to plummeting temperatures and shifted weather patterns across the hemisphere. However\, researchers have not been certain how the Gulf Stream\, one arm of this beast\, might play a role in the AMOC collapse. \nTo find out\, climatologists at Utrecht University in the Netherlands used computer modeling and real-world data to study how two ocean current systems interact. The findings indicate that the movement of the Gulf Stream could be a “canary in the coal mine” for the AMOC’s collapse. According to their analysis of satellite data\, the Gulf Stream has already been nudged northwards from the coast near Cape Hatteras\, North Carolina\, since the early 1990s. This is likely to be the result of the AMOC dwindling and losing its grip. Looking ahead\, the models forecast that further weakening of the AMOC will shift the Gulf Stream even further. At one key longitude (71.5°W)\, the current slowly drifts north by about 133 kilometers over several centuries\, followed by a sudden jump northward of about 219 kilometers within just two years in the model. This abrupt change is much larger than the normal year-to-year variation in the current’s position. In a punchline: the study ‘Abrupt Gulf Stream path changes are a precursor to a collapse of the Atlantic Meridional Overturning Circulation‘ concludes that a noticeable shift in the Gulf Stream’s position could signal that the AMOC is approaching a tipping point. While the scientific community remains divided on whether a total collapse is imminent\, monitoring the movement of the Gulf Stream could be an invaluable way to predict a terminal decline in the AMOC and our planet’s climate. \nLinks:\nThe Gulf stream is moving north – and it could be an early warning sign

SUMMARY:Confluence of European Water Bodies 2025
DESCRIPTION:From 21 to 24 September 2025\, representatives of more than 35 European seas\, lakes\, rivers\, wetlands\, lagoons\, and glaciers will confluence in the Netherlands. \nWhen two or more rivers meet in a landscape\, they flow together and continue as one body of water: they ‘confluence’. The Confluence 2025 is a growing interdisciplinary community of water representatives that strives for new dialogues and relationships with Europe’s water bodies. The network was founded by the Embassy of the North Sea\, TBA21–Academy\, and ILP Mar Menor. The first edition of the Confluence took place in 2023 at the Mar Menor in Spain – the first European ecosystem to be granted the status of a legal entity. In 2024\, this ever-growing community of water bodies gathered at the Venice lagoon. The Confluence of European Water Bodies 2025 will open in Amsterdam on 21 September 2025\, inaugurated by the British writer Robert Macfarlane\, followed by a three-day programme organised by the Embassy of the North Sea. During the Confluence we will be exploring new ways to represent water in the cultural\, political and legal domain. The programme\, taking place in Amsterdam and Bergen aan Zee\, includes workshops\, lectures\, films\, art installations\, performances\, concerts\, and future thinking sessions. The general public is very welcome at the public venues including De Balie\, UvA\, Mediamatic\, the Amstelkerk and Filmtheater Cinebergen. \nLinks:\nConfluence of European Water Bodies 2025 \nMeren\, rivieren en zeeën moeten mee kunnen praten over de toekomst

SUMMARY:Physics-Based Indicators for the Onset of an AMOC Collapse Under Climate Change - publication
DESCRIPTION:There is a growing risk that the Atlantic meridional overturning circulation (AMOC) collapses to a significantly weaker state under climate change\, researchers write in the Research Article “Physics-Based Indicators for the Onset of an AMOC Collapse Under Climate Change“. \nThis AMOC tipping event causes a substantial shift of the global climate. It is therefore important to assess the risk of such an event under future climate change\, but this requires long climate model simulations which are not always available. A robust indicator is developed\, that accurately predicts the onset of an AMOC tipping event and works under different forcing configurations and for different climate model simulations. Under a high-emission scenario (SSP5-8.5)\, the likelihood of an AMOC tipping event occurring in the century is high and reduces for lower emission scenarios (SSP2-4.5). If the AMOC starts to collapse\, it takes more than 100 years to reach a substantially weaker state. During that transition\, the Northwestern European climate would change drastically and is expected to see colder winters\, less rainfall\, and more severe winter storms. \nLinks:\nGevreesd kantelpunt in de Golfstroom mogelijk al halverwege deze eeuw bereikt \nPhysics- based early warning signal shows that AMOC is on tipping course

SUMMARY:Immense hoeveelheid plastic zweeft als nanodeeltjes in de oceaan / Nanoplastic concentrations across the North Atlantic - publication
DESCRIPTION:In de bovenste laag van de Atlantische Oceaan zweven naar schatting 27 miljoen ton aan nanoplastics –  minuscule deeltjes van minder dan 1 micrometer\, blijkt uit onderzoek in Nature. \n\nDat de oceanen vervuild zijn met plastic\, is al lang geen nieuws meer. Elke dag belandt er meer dan een miljoen kilogram plastic plastic in het water\, en steeds meer onderzoeken waarschuwen voor de gevolgen voor mens en milieu. Maar de meeste aandacht ging naar zichtbare stukken plastic. Over nanoplastics\, minuscule stukjes die minder dan een vijftigste van een menselijk haar meten\, is veel minder geweten. Nu blijkt uit het Nederlandse onderzoek dat die vervuiling veel groter is dan werd gedacht. Voor dit onderzoek nam een onderzoeksschip op twaalf locaties watermonsters waar alles dat groter dan één micrometer was werd uitgefilterd. Vervolgens werd het overblijvende materiaal gedroogd en geanalyseerd. Door de resultaten van verschillende locaties te extrapoleren naar de Noord-Atlantische Oceaan\, komen de onderzoekers tot de immense hoeveelheid van 27 miljoen ton nanoplastics\, daarmee is wel een belangrijk antwoord gevonden op de paradox van het missende plastic. Die paradox slaat op het verschil tussen de hoeveelheid geproduceerd plastic en de hoeveelheid afval. Een groot deel blijkt nu dus als minuscule\, ‘onzichtbare’ deeltjes in het water te zweven. \nLinks:\nImmense hoeveelheid plastic zweeft als nanodeeltjes in de oceaan

SUMMARY:#SaveOurOcean #WorldOceansDay / Wereld Oceanen Dag 2025
DESCRIPTION:World Ocean Day is an international day that takes place annually on 8 June. \nThe concept was originally proposed in 1992 by Canada’s International Centre for Ocean Development (ICOD) and the Ocean Institute of Canada (OIC) at the Earth Summit – UN Conference on Environment and Development (UNCED) in Rio de Janeiro\, Brazil. World Oceans Day was officially recognised by the United Nations in 2008. The international day supports the implementation of worldwide Sustainable Development Goals (SDGs)\, and fosters public interest in the management of the ocean and its resources. The day is marked in a variety of ways\, including launching new campaigns and initiatives\, special events at aquariums and zoos\, outdoor explorations\, aquatic and beach cleanups\, educational and conservation action programs\, art contests\, film festivals\, and sustainable seafood events. Youth have been playing an increasingly important role since 2015. The World Oceans Day Youth Advisory Council has been helping lead conservation awareness and action efforts globally since 2016. \nLinks:\nWorld Oceans Day \nWorld Oceans Day 8 June \nWorld Oceans Day 2020 – YouTube afspeellijst \nWorld Whale Day / Wereld Walvisdag \nWorld Oceans Day / Wereld Oceanen Dag \n7 ocean mysteries scientists haven’t solved yet \n2022 UN Ocean Conference \n5 Actions You can Take to #SaveOurOcean \nSeascape: the state of our oceans \nZo ziet de industriële visserij eruit

DESCRIPTION:Het Nederlandse bedrijf Allseas wil de oceaanbodem plunderen voor het winnen van metalen: samen roepen we Allseas op te stoppen! \nAllseas is een belangrijke aanjager van diepzeemijnbouw\, een beginnende industrie met grote\, schadelijke gevolgen voor de oceanen. Op dit moment is diepzeemijnbouw in internationale wateren nog niet toegestaan\, maar bedrijven zoals Allseas zetten druk op de Internationale Zeebodemautoriteit om diepzeemijnbouw op korte termijn groen licht te geven. In de tussentijd ontwikkelden ze het eerste diepzeemijnbouwschip ter wereld en werken ze aan verdere ontwikkelingen. Honderden experts en wetenschappers waarschuwen echter voor de mogelijk onomkeerbare en grootschalige schade aan de ecosystemen en de biodiversiteit in de diepzee. Samen kunnen we een krachtig signaal sturen naar mijnbouwbedrijven dat de bescherming van onze oceanen een absolute prioriteit is. \nLinks:\nStuur een kaart naar Allseas! \nAgenda – Stop diepzeemijnbouw voor het begint / Stop diepzeemijnbouw : Noorwegen\, zeg NEE tegen diepzeemijnbouw! – petities

SUMMARY:Intergovernmental Conference on Marine Biodiversity of Areas Beyond National Jurisdiction / BBNJ Agreement
DESCRIPTION:In its resolution 77/248 on “Oceans and the law of the sea”\, the General Assembly requested the Secretary-General to convene the resumed fifth session of the Intergovernmental Conference on Marine Biodiversity of Areas Beyond National Jurisdiction. \nIn its resolution 72/249 of 24 December 2017\, the General Assembly decided to convene an Intergovernmental Conference\, under the auspices of the United Nations\, to consider the recommendations of the Preparatory Committee established by resolution 69/292 of 19 June 2015 on the elements and to elaborate the text of an international legally binding instrument under the United Nations Convention on the Law of Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction\, with a view to developing the instrument as soon as possible. In accordance with resolution 72/249\, the Conference held a three-day organizational meeting in New York\, from 16 to 18 April 2018\, to discuss organizational matters\, including the process for the preparation of the zero draft of the instrument. The first session was convened from 4 to 17 September 2018\, the second session from 25 March to 5 April 2019 and the third session from 19 to 30 August 2019. The fourth session\, which was postponed by decisions 74/543 and 75/570 owing to the COVID-19 pandemic\, was convened from 7 to 18 March 2022. A fifth session of the Conference was convened from 15 to 26 August 2022 pursuant to General Assembly decision 76/564 (available as A/76/L.46). \nOn the last day of that session\, the Conference\, in considering the way forward\, decided to suspend the fifth session and resume it at a later date to be determined. Pursuant to resolution 77/248 of the General Assembly\, the resumed fifth session of the Intergovernmental Conference met from 20 February to 3 March 2023.  At the end of that meeting\, the Conference decided to resume at a later date with a view to adopting the agreement. In this connection\, the General Assembly\, in its decision 77/556 of 18 April 2023 (currently available as document A/77/L.62)\, requested the Secretary-General to convene a further resumed fifth session of the conference on 19 and 20 June 2023\, tentatively\, or on a date to be determined in consultation with the President of the conference. Accordingly\, the further resumed fifth session was held at UN Headquarters in New York on 19 and 20 June 2023. On 19 June 2023\, the Conference adopted\, by consensus\, the Agreement under the United Nations Convention on the Law of the Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction (A/CONF.232/2023/4). The Conference was closed on 20 June 2023. \nThe Agreement under the United Nations Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas beyond National Jurisdiction or BBNJ Agreement\, commonly known as the High Seas Treaty\, is a legally binding instrument for the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction. There is some controversy over the popularized name of the agreement. It is an agreement under the United Nations Convention on the Law of the Sea (UNCLOS). The text was finalised during an intergovernmental conference at the UN on 4 March 2023 and adopted on 19 June 2023. Both states and regional economic integration organizations can become parties to the Agreement. In 2017\, the United Nations General Assembly (UNGA) voted to convene an intergovernmental conference (IGC) to consider establishing an international legally binding instrument (ILBI) on the conservation and sustainable use of marine biodiversity beyond national jurisdiction (BBNJ). This was considered necessary because UNCLOS did not provide a framework for areas beyond national jurisdiction. There was a particular concern for marine biodiversity and the impact of overfishing on global fish stocks and ecosystem stability. The treaty addresses four themes: \n(1) marine genetic resources (MGRs) and their digital sequence information\, including the fair and equitable sharing of benefits;\n(2) area-based management tools (ABMTs)\, including marine protected areas (MPAs); (3) environmental impact assessments (EIAs);\n(4) capacity building and transfer of marine technology (CB&TMT). \nThe area-based management tools and environmental impact assessments relate mainly to conservation and sustainable use of marine biodiversity\, while the marine genetic resources and capacity building and transfer of marine technology include issues of economic justice and equity. Greenpeace called it “the biggest conservation victory ever”. The main achievement is the new possibility to create marine protected areas in international waters. By doing so the agreement now makes it possible to protect 30% of the oceans by 2030 (part of the 30 by 30 target). Though the agreement does not directly address climate change\, it also serves as a step towards protecting the ecosystems that store carbon in sediments. The High Seas Treaty has 76 articles and two annexes. One of its main aims is “s stewards of the ocean in areas beyond national jurisdiction on behalf of present and future generations by protecting\, caring for and ensuring responsible use of the marine environment\, maintaining the integrity of ocean ecosystems and conserving the inherent value of biological diversity of areas beyond national jurisdiction”. \nThe Agreement recognizes traditional knowledge. It has articles regarding the “polluter-pays” principle\, and different impacts of human activities including areas beyond the national jurisdiction of the countries making those activities. The agreement was adopted by the 193 United Nations Member States. Before entering into force\, the treaty needed to be ratified by at least 60 UN member states. The former treaty\, UNCLOS\, was adopted in 1982 and entered into force in 1994. As of October 2024\, UNCLOS has 170 parties. The European Union pledged financial support for the process of ratification and implementation of the treaty. On 19 September 2025\, Morocco became the 60th country to ratify the agreement\, setting the stage for its entry into force on January 17\, 2026. \nLinks:\nAgreement on Marine Biological Diversity of Areas beyond National Jurisdiction \nVerdrag voor de oceanen \nUN delegates reach historic agreement on protecting marine biodiversity in international waters \nAgreement under the United Nations Convention on the Law of the Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction (19 June 2023) \nVN-verdrag is mijlpaal voor internationale oceaanbescherming \nStop diepzeemijnbouw voor het begint / Stop diepzeemijnbouw : Noorwegen\, zeg NEE tegen diepzeemijnbouw! – petities \nAgenda – 29th Session of the International Seabed Authority Part I (TV ISA Web TV) \n2025 UN Ocean Conference \n#30thSessionCouncil #DeepSeabed #TheArea #UNCLOS 30th Session of the International Seabed Authority Part I (TV ISA Web TV)

SUMMARY:Record High Temperatures in the Ocean in 2024 - publication
DESCRIPTION:Study ‘Record High Temperatures in the Ocean in 2024‘ shows heating in the ocean has continued in 2024 in response to increased greenhouse gas concentrations in the atmosphere\, despite the transition from an El Niño to neutral conditions. \nIn 2024\, both global sea surface temperature (SST) and upper 2000 m ocean heat content (OHC) reached unprecedented highs in the historical record. The 0–2000 m OHC in 2024 exceeded that of 2023 by 16 ± 8 ZJ (1 Zetta Joules = 1021 Joules\, with a 95% confidence interval) (IAP/CAS data)\, which is confirmed by two other data products: 18 ± 7 ZJ (CIGAR-RT reanalysis data) and 40 ± 31 ZJ (Copernicus Marine data\, updated to November 2024). The Indian Ocean\, tropical Atlantic\, Mediterranean Sea\, North Atlantic\, North Pacific\, and Southern Ocean also experienced record-high OHC values in 2024. The global SST continued its record-high values from 2023 into the first half of 2024\, and declined slightly in the second half of 2024\, resulting in an annual mean of 0.61°C ± 0.02°C (IAP/CAS data) above the 1981–2010 baseline\, slightly higher than the 2023 annual-mean value (by 0.07°C ± 0.02°C for IAP/CAS\, 0.05°C ± 0.02°C for NOAA/NCEI\, and 0.06°C ± 0.11°C for Copernicus Marine). The record-high values of 2024 SST and OHC continue to indicate unabated trends of global heating. \nLinks:\nOok diepere lagen van de oceaan warmen op

SUMMARY:Stop de herrie & red onze zeedieren! - petitie
DESCRIPTION:Ze hebben geluid nodig om te overleven — maar door de herrie die commerciële schepen onder water veroorzaken\, krijgen de dieren in onze Noordzee het steeds moeilijker. \nNu is er bij de EU een voorstel om het volume omlaag te draaien\, walvissen\, dolfijnen en andere zeedieren te helpen en het aantal dodelijke aanvaringen terug te schroeven. Van de kleinste visjes tot de grootste walvissen: het gros van onze zeedieren is afhankelijk van geluid om te overleven. Dolfijnen en walvissen gebruiken geluid om sociale banden te onderhouden\, te jagen en op lange afstand te communiceren. Veel vissen gebruiken geluid om paringspartners te vinden en roofdieren te spotten. Maar onze zeeën zijn luid geworden. Commerciële schepen overstemmen de natuurlijke geluiden in zee en brengen onze zeedieren in gevaar. Ook in onze Noordzee zijn de gevolgen van toenemend onderwatergeluid groot voor het leven onder water — en het wordt alleen maar drukker. Nu kan Europa het volume lager zetten met een simpel\, haalbaar en praktisch besluit: door een voorstel voor een ‘blauwe’ snelheidsbeperking voor commerciële schepen aan te nemen. Als die 5 tot 10% trager varen\, zou de geluidsvervuiling volgens experts al met 25% dalen! Sluit je nu aan; samen maken we dit een luide burgeroproep die ze niet kunnen negeren! \nLinks:\nStop de herrie & red onze zeedieren! \nHelp ons om oceanen veiliger en stiller te maken voor walvissen!

SUMMARY:Formation of the Atlantic Meridional Overturning Circulation lower limb is critically dependent on Atlantic-Arctic mixing - publication
DESCRIPTION:Deep-water formation in the eastern Subpolar North Atlantic Ocean (eSPNA) and Nordic Seas is crucial for maintaining the lower limb of the Atlantic Meridional Overturning Circulation (AMOC)\, of consequence for global climate. \nHowever\, it is still uncertain which processes determine the deep-water formation and how much Atlantic and Arctic waters respectively contribute to the lower limb. To address this\, the reseachers used Lagrangian trajectories to diagnose a global eddy-resolving ocean model that agrees well with recent observations highlighting the eSPNA as a primary source of the AMOC lower limb. Comprised of 72% Atlantic waters and 28% Arctic waters\, the density and depth of the AMOC lower limb is critically dependent on Atlantic-Arctic mixing\, primarily in the vicinity of Denmark Strait. In contrast\, Atlantic waters gaining density through air-sea interaction along the eastern periphery of Nordic Seas and not entering the Arctic Ocean make a negligible contribution to the lower limb. \nLinks:\nFormation of the Atlantic Meridional Overturning Circulation lower limb is critically dependent on Atlantic-Arctic mixing \nPredicting the contribution of climate change on North Atlantic underwater sound propagation – publication

SUMMARY:Dwellers in the Deep: Biological Consequences of Dark Oxygen - publication
DESCRIPTION:Scientists have discovered “dark oxygen” being produced in the deep ocean\, apparently by lumps of metal on the seafloor. \nAbout half the oxygen we breathe comes from the ocean. But\, before this discovery\, it was understood that it was made by marine plants photosynthesising – something that requires sunlight. Here\, at depths of 5km\, where no sunlight can penetrate\, the oxygen appears to be produced by naturally occurring metallic “nodules” which split seawater – H2O – into hydrogen and oxygen. Several mining companies have plans to collect these nodules\, which marine scientists fear could disrupt the newly discovered process – and damage any marine life that depends on the oxygen they make. \nLinks:\nEvidence of dark oxygen production at the abyssal seafloor – publication \nStop diepzeemijnbouw voor het begint / Stop diepzeemijnbouw : Noorwegen\, zeg NEE tegen diepzeemijnbouw! – petities \nOxygen discovery defies knowledge of the deep ocean

SUMMARY:Evidence of dark oxygen production at the abyssal seafloor - publication
DESCRIPTION:Deep-seafloor organisms consume oxygen\, which can be measured by in situ benthic chamber experiments. \nThe writers of the article “Evidence of dark oxygen production at the abyssal seafloor” report such experiments at the polymetallic nodule-covered abyssal seafloor in the Pacific Ocean in which oxygen increased over two days to more than three times the background concentration\, which from ex situ incubations we attribute to the polymetallic nodules. Given high voltage potentials (up to 0.95 V) on nodule surfaces\, the writers hypothesize that seawater electrolysis may contribute to this dark oxygen production. \nLinks:\nManganknollen : Sauerstoff aus der Tiefsee \nAgenda – Dwellers in the Deep: Biological Consequences of Dark Oxygen – publication  \nAgenda – 29th Session of the International Seabed Authority Part II (TV ISA Web TV)  \nStop diepzeemijnbouw voor het begint / Stop diepzeemijnbouw : Noorwegen\, zeg NEE tegen diepzeemijnbouw! – petities

SUMMARY:29th Session of the International Seabed Authority Part II (TV ISA Web TV)
DESCRIPTION:The 29th Session of the International Seabed Authority (ISA) Assembly and Council (Part II) will include the meetings of the ISA Council and Assembly\, the Council will meet from 15-26 July 2024\, and the Assembly will convene from 29 July to 2 August 2024. \nThe ISA is an autonomous international organization established under the 1982 UN Convention on the Law of the Sea (UNCLOS) and the 1994 Agreement relating to the Implementation of Part XI of UNCLOS. The Authority is the organization through which States parties to the Convention organize and control activities in the seabed\, ocean floor\, and subsoil beyond the limits of national jurisdiction. At annual sessions of the ISA\, representatives from its member States meet to discuss and formulate the work of the Authority and its Secretariat. Negotiations are underway to develop rules\, regulations\, and procedures (RRPs) relating to commercial exploitation of mineral resources from the deep sea. In July 2023\, the Council indicated that it “intends” to continue the elaboration of RRPs\, with a view to their adoption at the ISA’s 30th session in 2025. \nLinks:\n29th Session of the International Seabed Authority \n29th Session of the International Seabed Authority Assembly and Council (Part II) \nStop diepzeemijnbouw voor het begint / Stop diepzeemijnbouw : Noorwegen\, zeg NEE tegen diepzeemijnbouw! – petities \n29th Session of the International Seabed Authority Part I (TV ISA Web TV) \n9 nadelen van diepzeemijnbouw: waarom de oceaan geen mijnbouwgebied mag worden \nAgenda – Evidence of dark oxygen production at the abyssal seafloor – publication  \nISA Web TV

SUMMARY:Protection of the Arctic from heavy grade oils / MARPOL regulation 43A - coming into effect
DESCRIPTION:On 1 November 2022\, amendments to the MARPOL regulation Annex I (addition of a new regulation 43A) entered into force\, introducing a prohibition on the use and carriage for use as fuel of heavy fuel oil (HFO) by ships in Arctic waters on and after 1 July 2024. \nThe prohibition covers the use and carriage for use as fuel of oils having a density at 15°C higher than 900 kg/m3 or a kinematic viscosity at 50°C higher than 180 mm2/s. Ships engaged in securing the safety of ships\, or in search and rescue operations\, and ships dedicated to oil spill preparedness and response are exempted. Ships which meet certain construction standards with regard to oil fuel tank protection need to comply on and after 1 July 2029. A Party to MARPOL with a coastline bordering Arctic waters may temporarily waive the requirements for ships flying its flag while operating in waters subject to that Party’s sovereignty or jurisdiction\, up to 1 July 2029. The MEPC has adopted a resolution which urges Member States and ship operators to voluntarily use distillate or other cleaner alternative fuels or methods of propulsion that are safe for ships and could contribute to the reduction of Black Carbon emissions from ships when operating in or near the Arctic. The resolution encourages Member States to commence addressing the threat to the Arctic from Black Carbon emissions\, and report on measures and best practices to reduce Black Carbon emissions from shipping. \nLinks:\nShipping in polar waters \nHFO ban in Arctic waters effective from 2024 \nVerbod op stookolie rond de Noordpool is een historisch besluit
