Increasing influence of warm and salty Atlantic water on the cold season Arctic sea ice melting

The Arctic Ocean in the upper 100 - 200 m is typically characterized by a cold and fresh surface mixed layer and a layer of rapidly increasing salinity with depth, as known as halocline, separating the surface mixed layer from the warm and salty Atlantic water at depth. Due to large vertical density gradient and... Continue Reading →

What caused the abrupt reduction of the South Indian Ocean heat & sea level in 2014–2016 and the ensuing quick recovery?

A decade-long increase of the basin-wide sea level and heat content in the subtropical southern Indian Ocean (SIO) during 2004–2013 ended abruptly, immediately following the onset of the strong 2014–2016 El Niño. Interestingly, this unprecedented drop of the SIO heat quickly recovered during the weak 2017–2018 La Niña. A study recently published in Science Advances... Continue Reading →
