Eddy cancellation of the Ekman cell in subtropical gyres
Published 2016“…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?
Published 2010“…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. …”

Song recordings suggest feeding ground sharing in Southern Hemisphere humpback whales
Published 2022-08-01“…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
Published 2022“…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. …”

Estimating ocean net primary productivity from daily cycles of carbon biomass measured by profiling floats
Published 2023-04-01“…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
Published 2024-01-01“…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
Published 2022-01-01“…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. …”

Impact of security dilemma on Antarctica’s militarization
Published 2022-04-01“…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.…”

Antarctic lakes suggest millennial reorganizations of Southern Hemisphere atmospheric and oceanic circulation.
Published 2010“…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. …”
