Quantifying dissolution rates of Antarctic icebergs in open water by Olav Orheim, A. Barry Giles, T. H. (Jo) Jacka, Geir Moholdt

“…At any one time 130 000 icebergs are afloat in the Southern Ocean; 97% of these are too small to be registered in current satellite-based databases, yet the melting of these small icebergs provides a major input to the Southern Ocean. …”

Climate-carbon feedback of the high latitude ocean by Bronselaer, B

“…As a result, the net Southern Ocean wind stress feedback could be significant and even comparable to the temperature feedback. …”

Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2 °C global warming could be dangerous by J. Hansen, M. Sato, P. Hearty, R. Ruedy, R. Ruedy, M. Kelley, M. Kelley, V. Masson-Delmotte, G. Russell, G. Tselioudis, J. Cao, E. Rignot, E. Rignot, I. Velicogna, I. Velicogna, B. Tormey, B. Donovan, E. Kandiano, K. von Schuckmann, P. Kharecha, P. Kharecha, A. N. Legrande, M. Bauer, M. Bauer, K.-W. Lo, K.-W. Lo

“…Southern Ocean surface cooling, while lower latitudes are warming, increases precipitation on the Southern Ocean, increasing ocean stratification, slowing deepwater formation, and increasing ice sheet mass loss. …”

Regional and global impact of CO2 uptake in the Benguela Upwelling System through preformed nutrients by Claire Siddiqui, Tim Rixen, Niko Lahajnar, Anja K. Van der Plas, Deon C. Louw, Tarron Lamont, Keshnee Pillay

“…Here, the warming effect of upwelled waters increases CO2 partial pressure (pCO2) and outgassing in the entire system, but is exceeded in the south through biologically-mediated CO2 uptake through biologically unused, so-called preformed nutrients supplied from the Southern Ocean. Vice versa, inefficient nutrient utilization leads to preformed nutrient formation, increasing pCO2 and counteracting human-induced CO2 invasion in the Southern Ocean. …”

Microplastic Interactions and Possible Combined Biological Effects in Antarctic Marine Ecosystems by Roberto Bargagli, Emilia Rota

“…Antarctica and the Southern Ocean are the most remote regions on Earth, and their quite pristine environmental conditions are increasingly threatened by local scientific, tourism and fishing activities and long-range transport of persistent anthropogenic contaminants from lower latitudes. …”

High‐resolution satellite imagery meets the challenge of monitoring remote marine protected areas in the Antarctic and beyond by Michelle LaRue, Cassandra Brooks, Mia Wege, Leonardo Salas, Natasha Gardiner

“…This perspective specifies how recent advances in VHR studies have contributed to knowledge regarding occurrence, habitat suitability, and abundance of mesopredators in the Southern Ocean. We demonstrate how knowledge gained through VHR offers a cost‐effective and easily accessible method for collecting previously unobtainable data to inform a representative network of Southern Ocean MPAs, and how the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) could utilize this technology. …”

“…The robustness of this constraint depends upon the assumption that pristine Southern Ocean droplet number concentration is a suitable proxy for preindustrial concentrations. …”

The influence of warming patterns on passive ocean heat uptake by Newsom, E, Zanna, L, Khatiwala, S, Gregory, JM

“…This spread is likely linked to intermodel differences in ocean circulation, which our idealized results suggest may be dominated by differences in Southern Ocean and subtropical ventilation processes.…”

Eddy saturation of equilibrated circumpolar currents by Munday, D, Johnson, H, Marshall, D

“…This study uses a sector configuration of an ocean general circulation model to examine the sensitivity of circumpolar transport and meridional overturning to changes in Southern Ocean wind stress and global diapycnal mixing. …”
