• Biogeochemical controls on ammonium accumulation in the surface layer of the Southern Ocean.

  Authors:Shantelle Smith, Katye E. Altieri, Mhlangabezi Mdutyana, David R. Walker, Ruan G. Parrott, Sedick Gallie, et al.From:Biogeosciences (Vol. 19, Issue 3) Peer-Reviewed

  Feb. 7, 2022344 words Brief article The production and removal of ammonium (NH4+) are essential upper-ocean nitrogen cycle pathways, yet in the Southern Ocean where NH4+ has been observed to accumulate in surface waters, its mixed-layer cycling remains...

• The importance of alkyl nitrates and sea ice emissions to atmospheric NO.sub.x sources and cycling in the summertime Southern Ocean marine boundary layer.

  Authors:Jessica M. Burger, Julie Granger, Emily Joyce, Meredith G. Hastings, Kurt A. M. Spence, and Katye E. AltieriFrom:Atmospheric Chemistry and Physics (Vol. 22, Issue 2) Peer-Reviewed

  Jan. 21, 2022398 words Article Atmospheric nitrate originates from the oxidation of nitrogen oxides (NOx=NO+NO2) and impacts both tropospheric chemistry and climate. NO.sub.x sources, cycling and NO.sub.x to nitrate formation pathways are poorly...

• Summertime productivity and carbon export potential in the Weddell Sea, with a focus on the waters adjacent to Larsen C Ice Shelf.

  Authors:Raquel F. Flynn, Thomas G. Bornman, Jessica M. Burger, Shantelle Smith, Kurt A. M. Spence, and Sarah E. FawcettFrom:Biogeosciences (Vol. 18, Issue 22) Peer-Reviewed

  Nov. 24, 2021312 words Brief article The Weddell Sea represents a point of origin in the Southern Ocean where globally important water masses form. Biological activities in Weddell Sea surface waters thus affect large-scale ocean biogeochemistry. During...
