Research brief: Flexible definitions needed for fronts in Southern Ocean

February 25, 2020 3:12 pm Published by Comments Off on Research brief: Flexible definitions needed for fronts in Southern Ocean

This paper is a review article that stemmed from a debate within the Southern Ocean community. The paper explains how “fronts”, sharp boundaries between water masses, are defined, and what their effects might be on the biology of the Southern Ocean.

Research brief: Assessing surface heat flux products from observations over the Australian sector of the Southern Ocean

To better understand the biases and ultimately improve the quality of our climate records, CLEX researches and their collaborators undertook in situ measurements using the NOAA Physical Sciences Division flux system during the Clouds, Aerosols, Precipitation, Radiation, and Atmospheric Composition over the Southern Ocean (CAPRICORN) experiment in 2016.

Research brief: Southern Ocean vortices are changing

The energy of vortices in the Southern Ocean has increased over the past two decades due to an increase in the mean amplitude of the vortices rather than an increase in their number.

Graeme MacGilchrist (University of Princeton). Reframing the carbon cycle of the subpolar Southern Ocean. Global climate is critically sensitive to physical and biogeochemical dynamics in the subpolar Southern Ocean, since this is where the deepest, most carbon-rich layers of the world ocean outcrop and exchange carbon with the atmosphere. Here, we show that the conventional framework for the subpolar Southern Ocean carbon cycle, which attributes a dominant role to the vertical overturning circulation and shelf-sea processes, fundamentally misrepresents regional carbon...

Research brief: What caused the rapid decline in Antarctic sea ice in 2016?

January 18, 2019 10:43 am Published by Comments Off on Research brief: What caused the rapid decline in Antarctic sea ice in 2016?

Antarctic sea ice extent underwent a rapid decline in the spring of 2016 and is still well below average now. CLEX researchers have tied the decline to natural variability of both the atmosphere and ocean in two articles published in Nature Communications this month.
