Eddy cancellation of the Ekman cell in subtropical gyres by Doddridge, E, Marshall, D, Hogg, A

“…Using an idealized eddy-resolving model it is shown that Eulerian-mean Ekman pumping may be opposed by an eddy-driven circulation, analogous to the way in which the atmospheric Ferrel cell and the Southern Ocean Deacon cell are opposed by eddy-driven circulations. …”

Where do winds drive the Antarctic Circumpolar Current? by Allison, L, Johnson, H, Marshall, D, Munday, D

“…The strength of the Antarctic Circumpolar Current (ACC) is believed to depend on the westerly wind stress blowing over the Southern Ocean, although the exact relationship between winds and circumpolar transport is yet to be determined. …”

Anthropogenic and internal drivers of wind changes over the Amundsen Sea, West Antarctica, during the 20th and 21st centuries by P. R. Holland, G. K. O'Connor, T. J. Bracegirdle, P. Dutrieux, K. A. Naughten, E. J. Steig, E. J. Steig, D. P. Schneider, D. P. Schneider, A. Jenkins, J. A. Smith

“…Emissions mitigation influences wind trends over the deep Southern Ocean but has less influence on winds over the Amundsen Sea shelf, where internal variability creates a large and irreducible uncertainty. …”

Song recordings suggest feeding ground sharing in Southern Hemisphere humpback whales by Elena Schall, Divna Djokic, Erin C. Ross-Marsh, Javier Oña, Judith Denkinger, Julio Ernesto Baumgarten, Linilson Rodrigues Padovese, Marcos R. Rossi-Santos, Maria Isabel Carvalho Gonçalves, Renata Sousa-Lima, Rodrigo Hucke-Gaete, Simon Elwen, Susannah Buchan, Tess Gridley, Ilse Van Opzeeland

“…Abstract The Atlantic sector of the Southern Ocean (ASSO) has one of the highest densities of Antarctic krill (Euphausia superba) compared to other polar and subpolar regions, which attracts migratory baleen whale species to aggregate in this area for feeding. …”

Ocean heat uptake: drivers, variability and impacts by Aengenheyster, M

“…The global heat content response pattern is shown to be a linear combination of the responses to flux perturbations in individual ocean basins, primarily the North Atlantic and the Southern Ocean.</p> <p>We further investigate (Chapter 3) processes and forcings that regulate the ocean heat content change in the South Pacific Gyre, finding an important cooling contribution from a weakening of the ocean circulation as a response to high-latitude Southern Ocean heat flux forcing. …”

CCN measurements at the Princess Elisabeth Antarctica research station during three austral summers by P. Herenz, P. Herenz, H. Wex, A. Mangold, Q. Laffineur, I. V. Gorodetskaya, I. V. Gorodetskaya, Z. L. Fleming, M. Panagi, F. Stratmann

“…For particles larger than <span class="inline-formula">≈110</span>&thinsp;nm the Southern Ocean together with parts of the Antarctic ice shelf regions were found to be potential source regions. …”

Estimating ocean net primary productivity from daily cycles of carbon biomass measured by profiling floats by Adam C. Stoer, Katja Fennel

“…We estimate NPP in the region south of 30°S as ~11.4 Pg C yr−1, and south of 50°S (the Southern Ocean) as ~4.6 Pg C yr−1. We obtain comparable estimates when complementary daily cycles of oxygen are used instead (11.7 and 3.5 Pg C yr−1). …”

Collecting whales: processes and biases in Nordic museum collections by Lene Liebe Delsett

“…Norway was a major whaling nation, but the largest hunt for whales in the Southern Ocean in the mid-1900s is not reflected in the Norwegian museum collections, probably because of the commercial focus of the whaling industry and logistical challenges, combined with limited research interest in zoological specimens at that time. …”

Genomic analyses of fairy and fulmar prions (Procellariidae: Pachyptila spp.) reveals parallel evolution of bill morphology, and multiple species by Lara D. Shepherd, Colin M. Miskelly, Mariana Bulgarella, Alan J. D. Tennyson

“…Prions are small petrels that are abundant around the Southern Ocean. Here we use mitochondrial DNA (COI and cytochrome b) and nuclear reduced representation sequencing (ddRADseq) to examine the relationships within and between fairy (Pachyptila turtur) and fulmar (P. crassirostris) prions from across their distributions. …”

Alfred Eaton: a Victorian naturalist at the ends of the world by C. Leah Devlin

“…His observations of flightless polar and subpolar insects, in particular, lent support to the work of Challenger naturalist Henry Moseley and botanist Joseph Hooker on species dispersal in the Southern Ocean and on adaptations that arise in response to the unique selection pressures in harsh, isolated conditions.…”

Impact of security dilemma on Antarctica’s militarization by Ferhat Kökyay

“…However, factors such as the ever-growing need for the Continent’s resources, increasing human activities in the Continent due to global warming, and the advancing use of dual-use scientific/military equipment due to technological developments pose a danger as the militarization of the Continent and the Southern Ocean. In this study, the risk of the recent activities of the parties to create a security dilemma and the potential of the security dilemma to increase the Continent’s militarization are analysed.…”

On the Wind Power Input to the Ocean General Circulation by Zhai, X, Johnson, H, Marshall, D, Wunsch, C

“…Much of the increase occurs in the storm-track regions of the Southern Ocean, Gulf Stream, and Kuroshio Extension. This result holds irrespective of whether the ocean surface velocity is accounted for in the wind stress calculation. …”

Localization of abrupt change in the North Atlantic thermohaline circulation by Johnson, H, Marshall, D

“…These results suggest that Southern Ocean wind forcing is not important for North Atlantic overturning on decadal and shorter timescales.…”

Antarctic lakes suggest millennial reorganizations of Southern Hemisphere atmospheric and oceanic circulation. by Hall, B, Denton, G, Fountain, A, Hendy, C, Henderson, G

“…The phasing of millennial-scale oscillations in Antarctica relative to those elsewhere in the world is important for discriminating among models for abrupt climate change, particularly those involving the Southern Ocean. However, records of millennial-scale variability from Antarctica dating to the last glacial maximum are rare and rely heavily on data from widely spaced ice cores, some of which show little variability through that time. …”

Sixty years of radiocarbon dioxide measurements at Wellington, New Zealand: 1954–2014 by J. C. Turnbull, J. C. Turnbull, S. E. Mikaloff Fletcher, I. Ansell, G. W. Brailsford, R. C. Moss, M. W. Norris, K. Steinkamp

“…This developing Δ¹⁴CO₂ interhemispheric gradient is consistent with recent studies that indicate a reinvigorated Southern Ocean carbon sink since the mid-2000s and suggests that the upwelling of deep waters plays an important role in this change.…”
