Shoreline access, lack of parking found to be obstacles to shared usage of coastal resources in Rhode Island
There are obstacles when it comes to sharing marine space, infrastructure, and resources in Rhode Island, a recent study found. With the usage of the state's coastal and offshore waters increasing, University of Rhode Island professor of marine affai.....»»
Our digital 3D models of huge coral reefs could help revive these precious ecosystems
As a team of marine biologists, assessing the health of thousands of square meters of coral reef can be a daunting prospect. Often, we have to monitor some of the most biodiverse ecosystems on the planet, and there's a strict time limit due to the sa.....»»
Deeper corals may help shallow reefs recover in the Florida keys
Since the 1970s, coral reefs in the Florida Keys National Marine Sanctuary (FKNMS) have experienced catastrophic declines in coral cover, with as much as a 50% reduction between 1998 and 2011 alone. Although coral reefs within the FKNMS have been hea.....»»
Phytoplankton shield ice shelves from summer heat
In spring, stretches of Antarctic sea ice melt to form pockets of open water called polynyas, which make perfect homes for phytoplankton. These marine microbes can become so abundant that they turn the water green......»»
Small "no-take zone" can help protect critically endangered hammerhead shark in Columbia
Researchers are advocating for a "no-take zone" off the coast of Colombia after one of the world's smallest and most threatened hammerhead species was found to do very little traveling outside of a Marine Protected Area in the region......»»
Scientists track plastic waste in pristine Canada marine park
Old tires, discarded cups, and cigarette butts litter the magnificent Saguenay Fjord, a marine protected area in eastern Canada that attracts belugas and other whales seeking respite......»»
How plastic pollution poses challenge for Canada marine conservation
One of the largest producers of plastic waste per capita, Canada is struggling to protect its designated marine protected areas from this pollution, experts warn......»»
Mysterious Pacific Ocean sounds identified as a type of whale—a new AI app helps track them
A team of oceanographers and marine biologists from the NOAA Pacific Islands Fisheries Science Center and Oregon State University has identified a mysterious noise heard in the Pacific Ocean for two decades as the sounds of Bryde's whales......»»
Tropical cyclone intensity exacerbated by increasing depth of ocean mixed layer, finds study
Tropical cyclones can have severe consequences for both the marine and terrestrial environments, as well as the organisms and communities who inhabit them. In the oceans, there can be alterations in sea surface temperature that disrupt biological pro.....»»
Surface water sampling reveals large numbers of juvenile krill undetected by conventional monitoring methods
In 2018–2019, researchers of Wageningen Marine Research joined the Japanese research vessel Kaiyo-maru (Fisheries Agency Japan; FAJ) on an Antarctic expedition to sample the upper surface waters with the Surface and Under Ice Trawl. Results showed.....»»
Antarctic krill can lock away similar levels of carbon as seagrass and mangroves, finds study
