As we enter Ocean Conservancy’s 53rd year, we bring a powerful legacy of success to tough global challenges. We are the best equipped organization to protect and defend our ocean from its greatest threats. The root of that strength is the community of supporters who stand with Ocean Conservancy as we unite people, science and policy for the good of the ocean and everyone and everything that depends upon it. I send my deepest appreciation to every person who lent us their time, passion and support this year.
The year 2024 was one of incredible accomplishments in protecting our ocean from the crises of plastic pollution, biodiversity loss and climate change. As I do each year, I wanted to take a moment to reflect on our most recent victories and proudest moments of the last year even as we look forward to the coming year.

Achieving international climate action
There is no path to halting climate change without scaling up offshore wind, and Ocean Conservancy has been a key player in advancing this solution at the international level. At the global climate conference in late 2023 in Dubai (the UN Conference of Parties’ 28th gathering, or COP28), our intensive advocacy secured a change that will have international ramifications for decades to come. Thanks to Ocean Conservancy, the “report card” that nations use to track progress on their climate goals will now include clean ocean energy like offshore wind (OSW) as a key measure of progress. This ensures that nations are accountable for OSW’s responsible, rapid and just development. In 2024, we continued pushing the international community to act by releasing a first-of-its-kind analysis on the affordable financing of OSW in nations least able to afford it. At COP29 in Azerbaijan this November, the so-called “finance COP,” we called for the international community to commit to the funding necessary for developing countries to responsibly deploy offshore wind and other ocean-climate solutions.
Advancing scientific research into plastic pollution
In early 2024, researchers from Ocean Conservancy and the University of Toronto shared the results of startling new research, published in the journal Environmental Pollution, which found microplastics in 88% of protein samples tested. The samples were drawn from 16 different protein types destined for U.S. consumers, including seafood, pork, beef, chicken, tofu and three different plant-based meat alternatives. There were no statistical differences in microplastic concentrations between land- and ocean-sourced proteins, suggesting that humans are likely eating microplastics no matter what protein they choose. To date, there had been little research into whether microplastics enter the filets of the fish—the parts that are actually eaten by people—and little research into terrestrial protein sources like beef and chicken that make up a large part of the American diet. The study was covered in major news outlets like The Washington Post and PBS.
Safeguarding the Arctic
This year, we upheld legislative safeguards that prevent oil drilling in sensitive Arctic environments. Ocean Conservancy and our partners prevented the passage of legislation that included mandatory oil and gas leasing. We also launched a new campaign in partnership with Oceans North aiming to win an international agreement not to ship though, or mine from, Central Arctic Ocean waters. In an early win, Canada has already signaled support for our goals. This builds on our previous success negotiating a similar international agreement not to fish in these waters to protect this ocean that lies at the heart of the Arctic.
Scaling up for trash removal
Our work organizing the International Coastal Cleanup® (ICC), now in its 39th year, connects more than 485,000 volunteers annually to gather trash from our beaches and shores. Hands-on, individual actions for safe and healthy coastlines add up to a robust and thriving international movement. This year, thanks to a new partnership with the National Oceanic and Atmospheric Association (NOAA), Ocean Conservancy will take our effort to the next level and remove Large Marine Debris from U.S. coastal waters and support efforts by communities around the country to supercharge cleanup efforts. In addition to the unfathomable human and animal toll of recent hurricanes, the ensuing flooding marked the largest mass dumping of trash into the ocean in recent memory. Ocean Conservancy is here for the long haul to support coastal communities as they clean up and rebuild.
There are too many stories of success to tell them all in full, but this year we also:
- Recycled 81,073 pounds of end-of-life fishing gear through our Global Ghost Gear Initiative®, protecting countless marine animals from entanglement and death.
- Changed governance policy to advance ecosystem-based approaches to fisheries management.
- Reduced shipping and port pollution in California by requiring vessels to plug into shore power and reduce harmful emissions when in port. We also defeated bills that would weaken clean shipping standards and won a major commitment to develop new rules to accelerate eliminating emissions from large ocean-going vessels.
- Protected Florida’s coastlines with a state-wide ban on the intentional release of balloons, a particularly fatal type of pollution for seabirds and other marine animals.
- Celebrated the end to the #TeamSeas campaign, which smashed its goals ahead of schedule, cleaning more than 34 million pounds of trash from the ocean while inspiring a new generation of young people to join our movement.
- Launched an innovative partnership with three Florida universities to identify the sources of nitrogen pollution, which cause toxic algal blooms, in Florida waters.
I am inspired by the creativity, grit and determination our experts bring to this work. Catastrophic Gulf storms this year impacted Ocean Conservancy staff, as well as tens of millions of others across the country. Yet our incredible team kept defending and protecting our ocean, even while facing personal setbacks. That’s because we all recognize that our impact matters. And our impact is greater, thanks to supporters like you.
As conservationists who care deeply about our blue planet, we have much to celebrate from this year, as well as challenges to overcome. We are ready to turn the page and gear up for the critical years ahead.
Together, we can win a healthy ocean and a thriving planet, forever, and for everyone. I hope that you will stand with us in the year to come—our ocean needs you, now more than ever.

Between all the scientific work, we celebrated Easter on board, although the weather had other plans for us. Due to rough conditions, we weren’t able to carry out any CTD casts.
Easter itself was spent in a mix of rest and small celebrations. Some of us enjoyed a long Easter breakfast with traditional Easter bread, while others took the opportunity to sleep in. In the evening, we gathered with both crew and scientists for a small celebration. The ship’s cook even organized a quiz, and those who answered correctly were rewarded with Easter chocolate.
The next day, the weather improved, and we began early with the recovery of K1, a 3,495-meter-long mooring in the middle of the Labrador Sea.
We joined the nautical officers on the bridge before sunrise to search for it. Fortunately, K1 has a floating buoy with a light, so we were able to spot it even in the dark. The actual recovery started at first light, and it began to snow while we were working.
Amid all the CTDs and mooring operations, there was also a personal highlight: my (Sarah’s) birthday. Although I’ve spent birthdays away from home before, this one felt especially unique, being so far out at sea, with only limited internet contact.
Normally, I work the 4-8 shift, but my incredibly kind shift team gave me the morning off. That meant I could sleep in and even find time to call family and friends back home. In the afternoon, I was surprised with my favourite cake, baked by Julia.
Our work continued with the mooring array at 53°N, which consists of seven moorings. So far, we have recovered five (K7, K8, K9, DSOW1 and DSOW2), and three of them have already been redeployed (K7, K8 and DSOW1,).
Deploying K7 turned out to be particularly tricky. On our first attempt, sea ice drifted toward us faster than expected, forcing us to recover nearly half of the mooring again. While the ship itself can handle drifting ice, deploying a mooring is much more delicate: a long cable with instruments and floats is released behind the ship before the anchor is dropped, allowing the system to sink into place.
Two days later, we tried again and this time, the deployment was successful.
Afterwards, we moved closer to the sea ice, which was a highlight for many of us. Seeing the ice up close and even spotting a seal swimming nearby, made the experience unforgettable.
Due to the continuing harsh weather, the decision was made to return to K1 and make use of an upcoming weather window for deployment the following day.

Zwischen Stürmen und Wissenschaft: Ostern in der Labradorsee (04.04.26 – 13.04.26)
Zwischen all der wissenschaftlichen Arbeit haben wir Ostern an Bord gefeiert, auch wenn das Wetter andere Pläne für uns hatte. Aufgrund der rauen Bedingungen konnten wir keine CTD-Messungen durchführen (Messungen von Leitfähigkeit, Temperatur und Tiefe im Ozean).
Ostern selbst war eine Mischung aus Erholung und kleinen Feierlichkeiten. Einige von uns genossen ein ausgedehntes Osterfrühstück mit traditionellem Osterbrot, während andere die Gelegenheit nutzten, etwas länger zu schlafen. Am Abend kamen Crew und Wissenschaftler*innen zu einer kleinen Feier zusammen. Der Koch organisierte sogar ein Quiz, und wer die Fragen richtig beantwortete, wurde mit Oster-Schokolade belohnt.
Am nächsten Tag besserte sich das Wetter, und wir begannen früh mit der Bergung von K1, einer 3.495 Meter langen Verankerung mitten in der Labradorsee. (Eine Verankerung ist eine lange, am Meeresboden befestigter Draht, der mit Instrumenten ausgestattet ist, um über längere Zeit Ozeandaten zu messen.)
Noch vor Sonnenaufgang gingen wir mit den nautischen Offizieren auf die Brücke, um nach ihr Ausschau zu halten. Glücklicherweise verfügt K1 über eine schwimmende Boje mit Licht, sodass wir sie bereits im Dunkeln entdecken konnten. Die eigentliche Bergung begann bei Tagesanbruch und es begann sogar zu schneien.
Zwischen all den CTD-Einsätzen und Verankerungsarbeiten gab es auch ein persönliches Highlight: meinen (Sarahs) Geburtstag. Obwohl ich schon öfter Geburtstage fernab von zu Hause verbracht habe, war dieser besonders, so weit draußen auf dem Meer und mit nur eingeschränktem Internetkontakt.
Normalerweise arbeite ich in der 4-8 Uhr Schicht, aber mein unglaublich nettes Schichtteam hat mir den Morgendienst freigegeben. So konnte ich etwas länger schlafen und hatte sogar Zeit, mit Familie und Freunden zu Hause zu telefonieren. Am Nachmittag wurde ich dann noch mit meinem Lieblingskuchen überrascht, den Julia für mich gebacken hat.
Unsere Arbeit ging weiter mit dem Verankerungs-Array bei 53°, das aus sieben Verankerungen besteht. Bisher haben wir fünf geborgen (DSOW1, DSOW2, K7, K8 und K9), von denen drei bereits wieder ausgebracht wurden (DSOW1, K7 und K8).
Das Ausbringen von K7 erwies sich als besonders schwierig. Beim ersten Versuch trieb das Meereis schneller auf uns zu als erwartet, sodass wir fast die Hälfte der Verankerung wieder einholen mussten. Obwohl das Schiff selbst gut durch treibendes Eis navigieren kann, ist das Ausbringen einer Verankerung deutlich anspruchsvoller: Dabei wird ein langer Draht mit Messinstrumenten und Auftriebskörpern hinter dem Schiff ausgesetzt, bevor am Ende der Anker gelöst wird und das gesamte System absinkt.
Zwei Tage später versuchten wir es erneut, diesmal mit Erfolg.
Anschließend fuhren wir näher an das Meereis heran, was für viele von uns ein besonderes Highlight war. Das Eis aus nächster Nähe zu sehen und sogar eine Robbe in der Nähe schwimmen zu beobachten, machte das Erlebnis unvergesslich.
Aufgrund der weiterhin rauen Wetterbedingungen wurde schließlich entschieden, zu K1 zurückzukehren, um ein bevorstehendes Wetterfenster für die Ausbringung am nächsten Tag zu nutzen.
Between Storms and Science: Easter in the Labrador Sea (04.04.26–13.04.26)
Ocean Acidification
Humans Just Flew Around the Moon This Week. But Would Babies Born There Ever Truly Feel Gravity? Ask Jellyfish Babies.
This week, NASA’s Artemis II crew made history by flying around the Moon and returning safely to Earth, the first human journey to the Moon’s vicinity in more than 50 years. It was a stunning reminder that humanity is no longer just dreaming about living beyond Earth. We are actively rehearsing for it.
And that leads to a much stranger, deeper question: even if one day we build skyscrapers on the Moon, raise families there, and turn space into a place to live, will babies born away from Earth develop a normal sense of gravity? Or will their bodies learn the universe differently?
To explore that question, NASA once turned to an unexpected stand-in for human babies: jellyfish babies. On the STS-40 mission, scientists sent thousands of tiny jellyfish polyps into space because jellyfish, like humans, rely on gravity-sensing structures to orient themselves. The experiment asked a simple but profound question: if a living body develops in microgravity, will it still know how to handle gravity later?
The answer was both fascinating and unsettling. The jellyfish developed in space in large numbers, but once back under Earth’s gravity, the ones that had developed in microgravity showed far more pulsing abnormalities than the Earth-grown controls. In other words, their bodies formed, but their sense of balance did not seem to work quite the same way.
That is why this old jellyfish experiment still matters today. Before we imagine lunar cities, schools, nurseries, and generations born off-world, we need to ask not only whether humans can survive in space, but whether developing there changes how the body understands something as basic as up, down, and movement. Jellyfish babies cannot tell us everything about human children, but they may have given us one of the first clues that life born beyond Earth might not come home unchanged.

After a slight delay of the Maria S. Merian caused by late-arriving containers our research cruise MSM142 finally got underway. By last Tuesday (24.03.2026), the full scientific team had arrived in Nuuk, the capital of Greenland, and the ship reached port on Wednesday (25.03.2026) morning. That same day, scientists and technicians moved on board and immediately began preparations, assembling and testing our instruments. Although the mornings on Wednesday and Thursday were grey and overcast, the afternoons cleared up beautifully. This gave us valuable time to organize equipment on deck and store empty boxes back into the containers before departure.
Given the forecast of harsh conditions outside the fjord, we carried out the mandatory safety drill while still in harbour. This included practicing emergency procedures and boarding the lifeboat. After completing border control, we were finally ready to leave Nuuk. We set sail on March 27th, heading into the Labrador Sea to begin our mission. Even before starting scientific operations, we tested the setup for deploying our gliders without releasing them during the transit out of the fjord. Once we reached open waters, we were met by high waves the following morning. For some on board, this was their first experience under such rough sea conditions. Seasickness quickly became a challenge for a few, while scientific work had to be temporarily postponed due to the strong winds and sea conditions. Together with the crew, we discussed how best to adapt our measurement plans to the given weather conditions. On March 29th, we were finally able to begin our scientific program with the first CTD deployment. A CTD is an instrument used to measure conductivity, temperature, and depth, which are key parameters for understanding ocean structure.
During the following night, we continued with additional CTD stations and successfully recovered two moorings: DSOW 3 and DSOW 4, located south of Greenland. These moorings carry instruments at various depths that measure velocity, temperature, and salinity. DSOW 4 was redeployed on the same day, while DSOW 3 followed the next day. In addition, the bottles attached to the CTD’s rosette can be used to collect water samples from any desired depth. These samples can be used, for example, to determine the oxygen content, nutrient levels, and organic matter.
Both are part of the OSNAP array, a network of moorings spanning the subpolar North Atlantic. On these moorings are a few instruments, for example microcats which measure temperature, pressure and salinity.
We then conducted around 25 CTD stations spaced approximately 3 nautical miles apart across an Irminger ring identified from satellite data. This high-resolution sampling was necessary to capture the structure of an Irminger Ring, which had a radius of about 12 km wide.
The days leading up to April 2nd were marked by very rough weather conditions. Life on board became both challenging and, at times, unintentionally entertaining sliding chairs were not uncommon. During the night from April 1st to April 2nd, winds reached 11 Beaufort with gusts up to 65 knots, forcing us to pause our measurements. Fortunately, conditions improved by morning, allowing us to resume our work. As well as with the help of the crew we had to adapt to the harsh weather conditions to continue our scientific work. On the 3rd of April, we were able to deploy a few gliders and one float. An ocean glider is an autonomous underwater Vehicle, which you can steer remotely and send to different locations, while it is measuring oceanographic key parameters.
This research cruise focuses on understanding small-scale processes in the ocean and their connection to the spring bloom, an essential phase in marine ecosystem in subpolar regions. Despite the challenging start, we have already gathered valuable data and look forward to the weeks ahead in the Labrador Sea.
