A large number of gray whales are starving and dying in the eastern North Pacific
It is now the third year that gray whales have been found in very poor condition or dead in large numbers along the west coast of Mexico, USA and Canada. A new international study now suggests that starvation is contributing to these mortalities.
Antarctica: the ocean cools at the surface but warms up at depth
Scientists from the CNRS, CNES, IRD, Sorbonne Université, l’Université Toulouse III – Paul Sabatier and their Australian colleagues*, with the support of the IPEV, have provided a comprehensive analysis on the evolution of Southern Ocean temperatures over the last 25…
Scientists discover how the potentially oldest coral reefs in the Mediterranean developed
A new study from the Institut de Ciències del Mar (ICM-CSIC, Spain) and the National Oceanography Centre brings unprecedented insights into the environmental constraints and climatic events that controlled the formation of these reefs. The results of this research will…
