Stunning Antarctic Sea Creatures Discovered After Iceberg Breaks Away (scientificamerican.com)
A large sponge, a cluster of anemones, and other life is seen nearly 230 meters deep at an area of the seabed that was very recently covered by the George VI Ice Shelf in Antarctica. Sponges can grow very slowly, sometimes less than two centimeters a year, so the size of this specimen suggests this community has been active for decades, perhaps even hundreds of years.

New NASA satellite mapped the oceans like never before (zmescience.com)
The ocean floor is a vast scope on our planet that remains largely unexplored. Although oceans cover 71% of Earth, we have clearer pictures of the Moon and Mars than we do of the landscape beneath the waves. But a newly launched satellite mission coined SWOT (Surface Water and Ocean Topography) is now giving scientists a much sharper picture of these hidden underwater worlds.

Meltwater from Greenland and the Arctic is weakening ocean circulation (theconversation.com)
A vast network of ocean currents nicknamed the “great global ocean conveyor belt” is slowing down. That’s a problem because this vital system redistributes heat around the world, influencing both temperatures and rainfall.

Plankton balloon to six times size in newly discovered mode of oceanic travel (phys.org)
Many plankton journey from the cold, dark depths of our oceans to the surface, only to eventually drift down again into the darkness in a perpetual rhythm. Yet, how single-celled phytoplankton, most of which have no appendages to help them swim, make this pilgrimage has remained a mystery.
