Dynamics and variability of the Subantarctic mixed-layer as determined from a high resolution glider dataset

Author: Du Plessis, Marcel David Date: 2015 Traditional understanding of mixed-layer (ML) dynamics in the African sector of the Southern Ocean suggests that seasonal summer stratification and subsequent reduction in ML depth (MLD) is determined by the onset of a positive net heat ux. ... Read more
Exploring South Africa’s southern frontier: A 20-year vision for polar research through the South African National Antarctic Programme

Author: Ansorge, Isabelle J ; Skelton, Paul ; Bekker, Annie ; de Bruyn, P J Nico ; Butterworth, Doug S ; Cilliers, Pierre ; Cooper, John ; Cowan, Don A ; Dorrington, Rosemary ; Fawcett, Sarah ; Fietz, Susanne ; Findlay, Ken P ; Froneman, P William ; Grantham, Geoff H ; Greve, Michelle ; Hedding, David ; Hofmeyr, G J Greg ; Kosch, Michael ; le Roux, Peter ; Lucas, Mike ; MacHutcho, Keith ; Meiklejohn, Ian ; Nel, Werner ; Pistorius, Pierre ; Ryan, Peter ; Stander, Johan ; Swart, Sebastiaan ; Treasure, Anne ; Vichi, Marcello ; Jansen van Vuuren, Bettine Date: Jun 2017 Antarctica, the sub-Antarctic islands and surrounding Southern Ocean are regarded as one of the planet’s last remaining wildernesses, ‘insulated from threat by [their] remoteness and protection under the Antarctic Treaty System’1 . Antarctica ... Read more c b
Intra-seasonal variability of Southern Ocean primary production: the role of storms and mesoscale turbulence

Author: Nicholson, Sarah-Anne Date: 2016 The Southern Ocean is one of the stormiest places on earth; here strong mid-latitude storms frequently traverse large distances of this ocean. Underlying these passing storms, the Southern Ocean is characterized by having some of the highest ... Read more
Quantifying spatial and temporal scales of phytoplankton variability in the Sub-Antarctic Ocean using a high-resolution glider dataset

Author: Little, Hazel Jean Date: 2016 Phytoplankton in the Sub-Antarctic Southern Ocean have a distinct seasonal cycle, which is highly variable in both space and time. The seasonal and spatial distribution of chlorophyll can be attributed to the complex nature of the physical ... Read more
The impact of submesoscales on the stratification dynamics in the Southern Ocean

Author: du Plessis, Marcel David Date: 2018 Submesoscale dynamics O(1-10 km, hours to days) are considered to strongly affect the stratification of the upper ocean. In the Southern Ocean, studies of submesoscale dynamics are biased to regions preconditioned for strong frontal activity ... Read more
Thermohaline variability of AAIW in the Atlantic sector of the Southern Ocean investigated using an Altimetry Gravest Empirical Mode

Author: Hutchinson, Katherine Alessandra Date: 2013 The southeast Atlantic sector of the Southern Ocean connects the Atlantic with the Indian Ocean and the Antarctic Circumpolar Current, thereby acting as a major conduit within global ocean circulation. Thermohaline transports in this region ... Read more
