As promised, this post provides an update on the ocean conditions during our return transit. Compared to the relative calm we enjoyed during the previous six weeks, the passage hit livelier conditions that led to tumult in the galley, tumbled more than a few stomachs and, not least, reminded us of the Beaufort Scale as a universally recognized guide for judging the effects of wind speed on the ocean.
‘Energetic,’ you say?
Most definitely. Expedition 400 Captain Harm Nienhuis reported that shortly after leaving the final drilling site of the expedition, the ship “encountered a strong gale for a while, a Beaufort Scale 9.” A Beaufort 9 is categorized as a “Severe Gale,” with winds ranging from 41 to 47 knots. This is the equivalent of 47 to 54 miles per hour. This causes what the Scale characterizes as “high waves” and crests that “began to topple, tumble, and roll over.” More poignantly, it caused the cancellation of the ritual of morning coffee on the deck.

How did this gale affect the voyage?
The strong wind resulted in waves of approximately six to seven meters (19.685 feet to 22.9659 feet), and the wind direction, blowing straight on the bow, significantly slowed our progress. A glance at the map 48 hours after our departure from the working site showed minimal movement as the JR crawled south toward the lower tip of Greenland.
Gales are one thing; gusts are a whole “other”
While gales are one challenge, gusts present an entirely different situation. A gust represents a sudden, often dramatic burst of wind speed. Meteorologist Erick Adame notes that, “to be classified as a wind gust, the brief increase in wind must be at least 10 miles per hour faster than the average wind speed.” During this gale, Captain Nienhuis reported that the seas delivered gusts of 50 to 55 knots, reaching Beaufort 10, which is considered storm force wind.
In his characteristically measured tone, he noted that these were not sustained winds, but rather intermittent gusts. Crew members certainly felt occasional bursts, with some retreating to their bunks to alleviate queasiness. We survived, swaggering out of our cabins like old salts; not realizing the real drama was yet to come.
The “Big Roll”
As we rounded the southern tip of Greenland, the wind from the portside and port quarter pushed us along, so we managed to keep the speed up to over 10 knots.

Gale force winds of 35 to 40 knots, equivalent to Beaufort Scale 8, presented additional challenges. These winds gradually shifted more forward to the port bow, further slowing us to a speed of about 8.5 knots. At this point, standard waves were between a sizeable six and seven meters (nearly 20 to 23 feet) in height, on average. As it turns out, nature scoffs at averages.
The final blow, a literal one, came when a portside wave that by the captain’s best guess was “around 10-to-12 meters” (32.8084- 39.3701feet) walloped the ship just in time for dinner. Nienhuis remarked,
“This one stood out.”

The smackdown tossed dishes and jars off of shelves in the galley. Even the microwave oven fell off of the counter. Remarkably, the expedition’s intrepid kitchen crew managed to resurrect the dinner and serve it up in less than half-an-hour. Fortunately, no one sustained serious injuries during this event. A crew member aptly dubbed this incident “the big roll” and even managed to capture it on film.
Admiral Beaufort would have been proud.

Plastic Pollution’s Toll on Seabirds
This blog was co-written by Dan Berkson and Hannah De Frond. Hannah works with Ocean Conservancy and the University of Toronto Trash Team to manage the International Trash Trap Network (ITTN), a global network of local groups using trash traps to increase cleanup efforts, engage communities and inform upstream solutions.
Plastic pollution devastates our ocean, and its impact on marine wildlife—especially seabirds—is severe and far-reaching. Seabirds breed on land but search for food at sea, bringing them into frequent contact with plastic pollution accumulating both along shores and in surface waters worldwide. Unfortunately, ingesting plastics can prove to be deadly for these amazing animals.

Eating plastics for seabirds can obstruct their digestive systems, preventing them from eating actual food, and leading to starvation. Sometimes it takes only one piece of plastic to block the passage of food. Plastic ingestion has been found in every family of seabird. Below are details on how some species are uniquely impacted by plastic pollution.
- Northern fulmar: Northern fulmars are surface feeders, diving into the ocean to snag prey. Unfortunately, their foraging habits bring them face to face with floating plastic fragments which they mistake for food. A 2015 study in the Arctic revealed a staggering 90% of northern fulmars studied had plastics in their stomachs. These creatures are so prone to eating plastics that both the Canadian government and OSPAR Commission (the mechanism through which the European Union and 15 other governments cooperate to protect the North East Atlantic marine environment) use this species in their monitoring programs to track long-term trends in ocean plastic pollution.

- Short-tailed shearwater: Short-tailed shearwaters are also particularly vulnerable to plastic pollution, frequently consuming both rubber—such as balloons—and hard fragments. A 2014 study in Tasmania found plastic in the stomachs of 96% of short-tailed shearwater chicks studied.
- Laysan albatross: The Laysan albatross skims the ocean surface with its beak to hunt for prey. This hunting behavior makes it likely that the albatross will accidentally consume plastic debris like consumer products (e.g., hard fragments, lighters, buttons) or fishing lines. Adult albatrosses also feed their chicks by regurgitating food, unknowingly passing plastics on to their young. A heartbreaking 1997 study on Midway Atoll, a remote Pacific island, found 97.5% of Laysan albatross chicks had plastic in their stomachs.

- Petrel: More than 50% of petrel species are listed as “threatened” or “near threatened” by the International Union for Conservation of Nature (IUCN). Petrels often inhabit areas with high concentrations of plastic pollution such as the high seas and mid-ocean gyres. Unlike other seabirds, they struggle to regurgitate plastic. This means the plastics they ingest tend to remain in their bodies for extended periods.

What can you do?
If we fail to take action, studies predict that 99% of seabird species will ingest plastic by 2050, which is devasting given how vulnerable seabirds are to even the smallest amount of plastic. Ocean Conservancy is committed to protecting our ocean, wildlife and communities from plastic pollution. But we can’t do it alone. Here is how you can join the fight:
- Reduce plastic use: To tackle our plastic pollution crisis, we need to use less plastic. We can each do our part by avoiding single-use plastics where possible in our daily lives from carrying a reusable water bottle and bag to skipping a straw. These small actions add up and collectively reduce the amount of plastic waste we create, while sending a clear signal to plastic producers that we are fed up with single-use plastics.
- Clean up plastic pollution before it enters the ocean: Cleaning up plastic waste, whether on the beach, along a river, or in your neighborhood park, helps eliminate the likelihood that it will later be consumed by seabirds or other marine life. One of the best ways to do this is by joining the International Coastal Cleanup® (ICC). Use our map to find a coordinator planning a cleanup in your region. Want something closer to home? Team up with friends and family to clean up your favorite beach or beloved park. If you see plastic on beaches, shores or elsewhere, remember to clean it up—it could save a seabird’s life.
- Push for policy change: Advocate for legislation to address plastic pollution by holding corporations accountable for the waste they create, expanding support for reuse and refill systems and much more. Visit Ocean Conservancy’s Action Center to see how you can get involved.

Learnings from the National Working Waterfronts Networks Conference
I recently represented Ocean Conservancy at the National Working Waterfronts Network Conference in San Diego. The conference brought together maritime industry leaders, policymakers and community advocates, all working toward a shared vision for the future of our waterfronts.
As an engineer, former mariner and ocean conservationist I know that decarbonizing our ports requires cross-sector partnerships. The discussions throughout the National Working Waterfronts Network Conference reinforced how essential it is to bring together experts from engineering, policy and workforce development to drive meaningful change towards port decarbonization.

Throughout the conference, I discussed the need for a comprehensive, systems-level approach that integrates infrastructure investment, regulatory alignment and workforce development. Preparing the workforce for decarbonization is just as crucial as deploying zero-emission technologies. Investments in training programs and workforce development initiatives will equip maritime professionals with the expertise needed for the next generation of sustainable shipping. Collaboration among industry, government and educational institutions should also be used to create comprehensive training programs that align with emerging port technologies and regulatory requirements.

Another highlight of the conference was seeing the eWolf. Designed by the marine company Cowley, the eWolf is the first fully electric tug in the United States. This cutting-edge vessel is 82 feet long and has a 70-ton bollard pull. It is powered by a 6-megawatt-hour battery system that eliminates emissions, equipped with onboard energy management systems to optimize power use and fitted with azimuth thrusters for enhanced maneuverability. This vessel drastically reduces harmful pollutants like nitrogen oxides, sulfur oxides and particulate matter, improving air quality for nearby communities while maintaining the performance required for commercial operations. It takes bold industry players like Crowley to lead the way toward port decarbonization—and, let’s be honest, eWolf is just a cool name.

I left the National Working Waterfronts Network Conference with a deeper appreciation for the professionals working to ensure our waterfronts remain vibrant, resilient and sustainable. The challenge ahead is clear: How do we scale these innovations while maintaining the economic viability of our ports and coastal industries?
The answer lies in open collaboration among industry leaders, policymakers and communities, accelerated adoption of zero-emission technologies, strategic investments in clean-energy infrastructure and bold decision-making prioritizing sustainability and economic growth. That’s why Ocean Conservancy is spearheading projects like the Green Ports Interactive Funding Tracker—an innovative resource that aims to empower port authorities, environmental managers and sustainability experts by providing real-time updates and comprehensive insights into available funding.
Now is the time to turn conversations into action. Ocean Conservancy is committed to working alongside partners across the maritime industry to drive a cleaner, more sustainable future. Take action now to help Ocean Conservancy address today’s biggest threats to our ocean, including the climate crisis and plastic pollution.

The Truth About Plastic Fragments
This blog was written by Hannah De Frond. Hannah works with Ocean Conservancy and the University of Toronto Trash Team to manage the International Trash Trap Network (ITTN), a global network of local groups using trash traps to increase cleanup efforts, engage communities and inform upstream solutions.
During coastal cleanup events, no matter where you are in the world, chances are you’ll encounter plastic items like bottles, bottle caps, straws and packaging. However, plastic fragments that are smaller and more difficult to see may be difficult to see within the sand or soil.
Plastic fragments are small hard pieces of plastic, typically formed as larger plastic items that break up in the environment. As plastics are exposed to sunlight, waves and winds, they become brittle, crack and break into pieces. With each item of plastic that enters the environment, there is the potential for it to break into hundreds or even thousands of fragments. Due to its small, lightweight nature, each fragment moves differently in the environment and can have a totally different fate. Some fragments get washed into the ocean and float on the surface or sink to the ocean floor, some become buried in a sandy beach, and some are blown further afield with strong winds.

Plastic fragments are found in many environments, including lakes, rivers, terrestrial sediments and coastal marine environments. Plastic fragments are removed each year in the “tiny trash” collected during Ocean Conservancy’s International Coastal Cleanup®. They are among the top 10 items reported by groups in the International Trash Trap Network, an initiative co-led by Ocean Conservancy and the University of Toronto Trash Team, using technologies to clean up our waterways.
One study in Brazil found 2,661 fragments in a 100-meter section of beach. Plastic fragments are also frequently reported in studies of plastic ingestion by wildlife such as fish, seabirds and turtles. Ingested plastic fragments can cause tissue damage and inflammation and can concentrate harmful chemical pollutants which have the potential to leach out inside the gut, negatively impacting animal health.
Just like other large plastic items, plastic fragments also undergo environmental weathering which causes them to break apart into even smaller pieces—microplastics (<5mm) and eventually into nanoplastics (<100nm). These micro- and nano-sized fragments are frequently found in the environment and, due to their size, are easily ingested by wildlife. One analysis of scientific research to date revealed that fragments are ingested by 19% of fish globally.
To reduce plastic fragment pollution, we need to tackle the problem at the source by reducing the production and use of larger plastic items, like single-use plastics, from which fragments are generated. This includes commonly used polluting items like plastic bottles, straws, food containers, cups and plates. By reducing our plastic waste, reusing as much as possible and recycling when possible, we can, collectively, have a huge impact.
Both Ocean Conservancy and the University of Toronto are deeply committed to ridding our ocean and planet of insidious and harmful plastic pollution through efforts like the International Trash Trap Network and the International Coastal Cleanup. Please join us in ensuring that our ocean and waterways are not overrun by microplastics or any form of plastic pollution.
