  • Climate change is ravaging the oceans. Some startups see a solution in marine carbon capture

    Marine carbon capture, a term for various methods that trap carbon deep in the ocean, can help mitigate climate change by reducing the amount of the greenhouse gas in the atmosphere. Startups around the U.S. are advancing helpful technologies.

  • The islands that went from whale hunting to whale watching

    The Azores archipelago transitioned from hunting whales to whale conservation and eco-tourism that support research by implementing whale watching guidelines and building up the new industry after whaling was banned.

  • New York City's Public School on an Island

    The Harbor School, a public high school located on Governors Island, prepares students to work in maritime fields and exposes them to public service careers such as the Coast Guard. They get the opportunity to do hands-on work in the community, including through a project to study the health of New York Harbor and a program that aims to re-establish the harbor's oyster population.

  • UWindsor undergrad cuts research costs with DIY erosion sensors

    A student at Canada’s University of Windsor is creating DIY transducers, which are devices that measure wave pressure, to help researchers track shoreline erosion from water vessels in a larger area than they could afford to study otherwise.

  • Could Human Pee Be the Key to Saving Seagrass?

    As ecologists look to protect failing seagrass ecosystems, they have turned to a surprising solution: crystallized human urine. In a lab study, seagrass treated with struvite — a crystalline substance formed from human wastewater — had five times more seagrass shoots than those treated with regular fertilizer. It’s difficult to get struvite commercially and it might not work in all types of environments, but if there is more of a supply, this part of human waste could help an important ecosystem.

  • Seaweed Inc.: As climate threatens lobster, Maine eyes new cash crop

    As harvesting lobsters becomes more uncertain along the Maine coast due to climate change, many fishers are turning to kelp farming as a way to diversify their income. Atlantic Sea Farms purchases 1 million pounds of kelp a year from dozens of farmers resulting in The Pine Tree State becoming one of the top aquaculture producers in the United States.

  • How Stony Brook University Scientists Gave Shinnecock Bay a New Life

    After planting clams in Shinnecock Bay in 2012, scientists at Stony Brook University were able to reverse the trends of red tide in the coastal New York waters. The bay restoration project resulted in 400,000 square meters of seagrass regrowth and the local clam population significantly grew.

  • Saving the Great Lakes, one laundry load at a time

    A pilot experiment in Canada shows that adding a filter on a washing machine can prevent microfibers from entering the wastewater system and ending up in marine ecosystems. After installing these filters on machines in a community, there was a 41 percent decrease of microfibers in the washing machine liquid waste. This will not keep all microfibers from ending up in the environment, but legislators are working on passing bills requiring manufacturers to get these filters installed on new machines.

  • Can Small Seaweed Farms Help Kelp Scale Up?

    Atlantic Sea Farms strives to create sustainable ocean livelihoods by growing seaweed, which is good for both people and the planet. It's nutritionally dense, provides an extra source of revenue for fishermen, and is environmentally low impact. Ongoing studies also indicate it might absorb carbon dioxide in the ocean and tamp down ocean acidification. In 2018, Atlantic Sea Farms was producing 30,000 wet pounds of seaweed a year but expects a harvest of 1.2 million pounds this year, making it the largest in the U.S.

  • Catching Crabs in a Suffocating Sea

    Frances Chan, a researcher at Oregon State University first came across hypoxia or dangerously low-levels of oxygen in the ocean in Oregon back in 2002. To better understand the issue and empower crab fishers whose livelihoods suffered as a result, he helped develop "small, low-cost oxygen sensors" that fit into their crab pots and read the levels of oxygen in water in real time as they fish. This year, 38 instruments were sent out on eight boats, and with time, the information could help fishers adapt.
