The coldest, near-bottom South Pacific waters originating from Antarctica are warming three times faster than they were in the 1990s, according to new research analyzing data from deep-diving ocean robots and research cruises.

Long-term melting may lead to release of huge volumes of cold, fresh water into the North Atlantic, impacting global climate.

Rising temperatures along the bottom of the Atlantic Ocean will force American lobsters farther offshore and into more northern waters, a new study finds. Climate models project that ocean bottom temperatures in the Atlantic along the U.S. East Coast may rise by up to 4.3 degrees Celsius (7.7 degrees Fahrenehit) by the end of the century. The new study’s results show these rising temperatures will likely make conditions in the American lobster’s southernmost range—less hospitable in the future for juveniles, pushing them farther north and into habitats farther offshore.

Rising sea levels could diminish the ability of Brazil’s coral reef systems to weaken incoming ocean waves, resulting in stronger waves hitting populated areas on the Brazilian coastline, according to new research.

By Madeleine Jepsen Beach-goers around the world who slather on sunblock before an ocean swim can unwittingly contribute to coral-reef bleaching. Oxybenzone, a chemical in many types of sunblock and some hair products, can cause coral bleaching and death by damaging the coral’s genetic material, according to researchers. A team of scientists has proposed a new way to remove oxybenzone from the ocean by using tiny, absorbent beads to soak …

Small ocean waves could play a bigger role in breaking up ice shelves than tsunamis or other large waves, a new study suggests. A new study examining vibrations in Antarctica’s Ross Ice Shelf finds small waves continuously impacting the ice shelf may create enough strain to extend existing cracks in the ice and potentially create new ones. An ocean wave of 1 centimeter (0.5 inches) in height can cause vibrations that repeatedly move the ice more than 20 centimeters (8 inches).

Antarctic sea ice – frozen ocean water that rings the southernmost continent – has grown over the past few decades but declined sharply in late 2016. By March of 2017 – the end of the Southern Hemisphere’s summer – Antarctic sea ice had reached its lowest area since records began in 1978. Puzzled scientists wanted to know why.

Each year, as sea ice starts to melt in the spring following its maximum wintertime extent, scientists still struggle to estimate exactly how much ice they expect will disappear through the melt season. Now, a new NASA forecasting model based on satellite measurements is allowing researchers to make better estimates.

What’s a glider? It is an underwater robot that “flies” around the sea going from the surface to the bottom of the seafloor collecting different types of science data.

We’ve done a lot of science this week! Since the last update, we’ve successfully towed the super sucker, started multi-coring, and upped our CTD tally to a whopping 87 casts, plus all the continuous surface underway data we’ve collected while steaming between sites. The scientists have some preliminary results and ideas about where they’d like to visit again (the beginning of the Wainwright line is of particular interest).
