Pine Island Glacier […]

Humpback whale and researchers pictured from a drone.

In a detailed review of the status of the world’s 126 […]

Greenland glaciers 2018. Credit: NIOZ, Kim Sauter A new global ice sheet reconstruction for the past 80,000 years. During ice ages, the global mean sea level falls because large amounts seawater are stored in the form of huge continental glaciers. Until now, mathematical models of the last ice age could […]

Plankton-feeding fishes often dominate the fish assemblage on oceanic coral reefs. Credit: Dr. Christina Skinner Study reveals open ocean waters once assumed to be unproductive are in fact teeming with an abundance of life on coral reefs. Since Charles Darwin’s day, the abundance of life on coral reefs has been […]

A simulated red dye tracer released from the Beaufort Gyre in the Artic Ocean (center top) shows freshwater transport through the Canadian Arctic Archipelago, along Baffin Island to the western Labrador Sea, off the coast of Newfoundland and Labrador, where it reduces surface salinity. At the lower left is Newfoundland […]

Whale Shark with dorsal fin damage.

The findings reveal that lacerations and abrasions, increasingly caused through collisions with […]

A humpback whale. The songs of fin whales can be used for seismic imaging of the oceanic crust, providing scientists a novel alternative to conventional surveying, a new study published this week in Science shows. Fin whale songs contain signals that are reflected and refracted within the crust, including the sediment and […]

In warming waters, the demand for oxygen of many fish species will increase, progressively approaching the maximum oxygen supply capacity of their respiratory organs. New tool gauges impacts of warming waters on over 200 fish species. Warming ocean waters could reduce the ability of fish, especially large ones, to extract […]
