Ice is melting at a surprisingly fast rate underneath Shirase Glacier Tongue in East Antarctica due to the continuing influx of warm seawater into the Lützow-Holm Bay.
The studied subglacial discharge plume
25 Mar 2021
For the first time, scientists have succeeded in continuous monitoring of a subglacial discharge plume, providing a deeper understanding of the glacier-fjord environment.

Computational models suggest that melting water originating in the deep interior of Greenland could flow the entire length of a subglacial valley and exit at Petermann Fjord, along the northern coast of the island. Updating ice sheet models with this open valley could provide additional insight for future climate change predictions.

Water layering is intensifying significantly in about 40% of the world's oceans, which could have an impact on the marine food chain. The finding, published in the Journal of Geophysical Research: Oceans, could be linked to global warming.

A molecular process that signals distress could also help corals adapt to climate change.
Surface current velocity (arrows) and bottom topography (shading) at the western North Pacific, emphasizing bottom rises at the depth of 5,000 meters to 6,000 meters.

Unveiling new strategies to improve future wireless underwater sensing networks for marine research and communication.
Reconstruction of the late Ediacaran (ca. 550 million years ago) sea floor with burrows of a worm-like animal.
12 Mar 2018
Researchers led by Nagoya University discover penetrative trace fossils from the late Ediacaran of western Mongolia, revealing earlier onset of the “agronomic revolution”.

Corals living in highly saline waters may be more tolerant to rising water temperatures.
New mutant coral symbiont alga able to switch symbiosis off
22 Feb 2018
Researchers have identified the first spontaneous mutant coral symbiont alga to not maintain a symbiotic relationship with its host.
Walruses huddling together on a block of ice in the Arctic Ocean in August 2012 right before the summer ice cover hit a record low in the following month.

Quantitative analysis has evidenced the acceleration system of melting ice: dark water surfaces absorb more heat than white ice surfaces, thus melting ice and making more water surfaces in the Arctic Ocean.
