SUMMARY:Stuur een kaart naar Allseas!
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);\n(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) \nHigh Seas Treaty Ratification Tracker

SUMMARY:VPRO #Tegenlicht : de strijd om de diepzee (TV internet / NPO 2)
DESCRIPTION:Tegenlicht is een informatief televisieprogramma van de VPRO maandelijks op de eerste zondag op NPO 2. \nDoor de VPRO wordt het programma bestempeld als documentaire op het vlak van politiek\, economie\, sociologie en wetenschap. Het programma stelt zich ten doel inzicht in de werking van de samenleving te verschaffen. \nWe willen allemaal in een elektrische auto rijden\, ons huis verwarmen via zonnepanelen en een was draaien op windenergie. Zo zijn we ‘goed bezig’. Hoewel? De metalen die we hiervoor nodig hebben\, worden nu gedolven uit mijnen in het Globale Zuiden. Een praktijk die niet zelden gepaard gaat met mensenrechtenschendingen en conflict. Maar: op de bodem van de diepzee zijn eveneens grote hoeveelheden kobalt\, nikkel en koper te vinden. Kan de diepzee een alternatief bieden voor mijnen op land? VPRO Tegenlicht duikt in de strijd om de diepzee. \nLinks:\nde strijd om de diepzee (bekijken) \nStop diepzeemijnbouw voor het begint / Stop diepzeemijnbouw : Noorwegen\, zeg NEE tegen diepzeemijnbouw! – petities

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:#SeaTheChange Coastal CleanUp Day 2024
DESCRIPTION:In samenwerking met vrijwilligersorganisaties en individuen over de hele wereld\, zet de International Coastal Cleanup® (ICC) mensen in om afval van de stranden en waterwegen van de wereld te verwijderen. \nDankzij miljoenen vrijwilligers over de hele wereld is de ICC een baken van hoop geworden\, dat actie leidt en inspireert ter ondersteuning van onze oceaan. Sinds het begin hebben meer dan 18 miljoen vrijwilligers meer dan 172 miljoen kilo afval verzameld. Plasticvervuiling is een enorm probleem voor onze oceaan\, maar zelfs kleine acties kunnen een groot verschil maken. Elke fles\, elk rietje\, elk stukje afval dat je opruimt\, kan leiden tot een schonere\, gezondere oceaan. Doe dit seizoen met ons mee om je lokale strand\, beek\, park of buurt op te ruimen. Wanneer we ons huis opruimen\, kunnen alle mensen die in de oceaan leven #SeaTheChange. \nLinks:\nCoastal CleanUp Day

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: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

SUMMARY:World Aquatic Animal Day / Wereld Waterdierendag 2024
DESCRIPTION:Klik op afbeelding om te lezen\nWorld Aquatic Animal Day is an annual day dedicated to aquatic animals. The event—launched for the first time on April 3\, 2020—is a project of the Aquatic Animal Law Initiative and the Animal Law Clinic at the Center for Animal Law Studies. \nEach year\, students take the lead at raising global awareness about these often forgotten nonhuman animals. Aquatic animals play a critical role in our societies and ecosystems. They are important not only as a group\, but also as valuable and exciting individuals with intrinsic worth. By “aquatic animals”\, we mean not only fish\, but also a myriad of other animals that live in water for most of their life: amphibians\, marine mammals\, crustaceans\, reptiles\, molluscs\, aquatic birds\, aquatic insects and even animals such as starfish and corals. Despite this\, aquatic animals are widely used and abused around the world and they face a multitude of different threats. There is an urgent need to give aquatic animals the proper consideration they deserve. Through law\, policy\, education\, advocacy and good stewardship of the earth\, our efforts to raise awareness of the plight of aquatic animals must rise to meet the immense challenges they now face. We must also consider our interactions with aquatic animals\, our treatment of them\, and the often-devastating impacts we are having on them and their habitats. On April 3rd each year\, please join us in celebrating these creatures and calling for action to protect aquatic animals through education\, law\, policy\, outreach and other avenues. With a different focus each year\, we will\, together\, highlight these issues and elevate their status. \nLinks:\nWorld Aquatic Animal Day \nKeeping aquatic animals off your plate is a great step in supporting sealife

SUMMARY:Predicting the contribution of climate change on North Atlantic underwater sound propagation - publication
DESCRIPTION:Since the industrial revolution\, oceans have become substantially noisier\, according to research by the sea research institute NIOZ\, University of Utrecht\, TNO and IMAU. \nThe noise increase is mainly caused by increased shipping\, resource exploration\, and infrastructure development affecting marine life at multiple levels\, including behavior and physiology. Together with increasing anthropogenic noise\, climate change is altering the thermal structure of the oceans\, which in turn might affect noise propagation. During this century\, we are witnessing an increase in seawater temperature and a decrease in ocean pH. Ocean acidification will decrease sound absorption at low frequencies (<10 kHz)\, enhancing long-range sound propagation. At the same time\, temperature changes can modify the sound speed profile\, leading to the creation or disappearance of sound ducts in which sound can propagate over large distances. The worldwide effect of climate change was explored for the winter and summer seasons using the (2018 to 2022) and (2094 to 2098\, projected) atmospheric and seawater temperature\, salinity\, pH and wind speed as input. Using numerical modelling\, we here explore the impact of climate change on underwater sound propagation. \n \nThe future climate variables were taken from a Community Earth System Model v2 (CESM2) simulations forced under the concentration-driven SSP2-4.5 and SSP5-8.5 scenarios. The sound modeling results show\, for future climate change scenarios\, a global increase of sound speed at different depths (5\, 125\, 300\, and 640 m) except for the North Atlantic Ocean and the Norwegian Sea\, where in the upper 125 m sound speed will decrease by as much as 40 m s−1. This decrease in sound speed results in a new sub-surface duct in the upper 200 m of the water column allowing ship noise to propagate over large distances (>500 km). In the case of the Northeast Atlantic Ocean\, this sub-surface duct will only be present during winter\, leading to similar total mean square pressure level (SPLtot) values in the summer for both (2018 to 2022) and (2094 to 2098). We observed a strong and similar correlation for the two climate change scenarios\, with an increase of the top 200 m SPLtot and a slowdown of Atlantic Meridional Overturning Circulation (AMOC) leading to an increase of SPLtot at the end of the century by 7 dB. \nLinks:\nMeer CO2 in de lucht zorgt voor meer lawaai onder water
