Increasing poleward intrusion of the Circumpolar Deep Water and its impact on the changing ocean-biogeochemistry of the Southern Ocean

A study published in Nature Geoscience (Bronselaer et al., 2020) analyzed new observations from autonomous floats with ocean-biogeochemical sensors (Bio-Argo) along with historical shipboard ocean measurements to document changes in Southern Ocean physical and ocean-biogeochemical variables (i.e., temperature, salinity, pH, concentrations of nitrate, dissolved inorganic carbon and oxygen) during the last two decades. Due to... Continue Reading →

Pantropical response to global warming and the emergence of a La Nina-like mean state trend

During the past century, the tropical Pacific Ocean has warmed significantly less than the other tropical oceansĀ  in response to increasing greenhouse gases (GHGs). This La Nina-like warming trend in the observations is in stark contrast to the El Nino-like warming trend projected by the Coupled Model Intercomparison Project (CMIP) models for both the 20th...
