Changing Biogeochemistry of the Southern Ocean and Its Ecosystem Implications
Sian F. Henley,Emma L. Cavan,Sarah E. Fawcett,Rodrigo Kerr,Thiago Monteiro,Robert M. Sherrell,Andrew R. Bowie,Philip W. Boyd,David K. A. Barnes,Irene R. Schloss,Tanya Marshall,Raquel Flynn,Shantelle Smith +12 more
TL;DR: The Southern Ocean plays a critical role in regulating global climate as a major sink for atmospheric carbon dioxide (CO2), and in global ocean biogeochemistry by supplying nutrients to the global thermocline, thereby influencing global primary production and carbon export as mentioned in this paper.

TL;DR: In this paper, the distribution of nanophytoplankton and their associated biogeochemical environments along 30°E across the Indian Southern Ocean (Subtropical Zone; STZ to Antarctic Zone; AZ) in July 2017 were investigated.

TL;DR: In this paper , the authors conducted kinetics experiments across the Southern Ocean south of Africa to investigate the dependence of ammonium uptake (summer, winter) and oxidation (winter) on NH4+ concentration.

Summertime productivity and carbon export potential in the Weddell Sea, with a focus on the waters adjacent to Larsen C Ice Shelf
Raquel Flynn,Thomas G. Bornman,Jessica M. Burger,Shantelle Smith,Kurt Spence,Sarah E. Fawcett +5 more
TL;DR: In this article, the authors measured net primary production (NPP), nitrogen(nitrate, ammonium, urea) uptake, and nitrification in the western WeddellSea at the Antarctic Peninsula (AP) and Larsen C Ice Shelf (LCIS), in the southwestern Weddingell Gyre (WG), and at Fimbul ice Shelf(FIS) in the east and west of the WG.
Air-Sea Ammonia Fluxes Calculated from High-Resolution Summertime Observations Across the Atlantic Southern Ocean
Katye E. Altieri,Kurt Spence,Shantelle Smith +2 more
- 03 Mar 2021
TL;DR: In this article, the authors measured the concentration of surface ocean ammonium and atmospheric ammonia gas every two hours across a latitudinal transect (34.5ºS to 61&# 186;S) of the Atlantic Southern Ocean during summer.
