TL;DR: Observations of internal wave velocity fluctuations show that enhanced turbulent mixing over rough topography in the Southern Ocean is remarkably intense and widespread, and thus needs to be represented in numerical simulations of the global ocean circulation and the spreading of biogeochemical tracers.

TL;DR: In this article, the authors present inferences of diapycnal diffusivity from a compilation of over 5200 microstructure profiles, supplemented with indirect measurements of mixing obtained from (i) Thorpe-scale overturns from mooring profiles, (ii) shipboard observations of upper-ocean shear, (iii) strain as measured by profiling floats, and (iv) shear and strain from full-depth loweredacoustic Doppler currentprofilers (LADCP) and CTD profiles.

TL;DR: A survey of Antarctic waters along the East Scotia Ridge in the Southern Ocean reveals a new vent biogeographic province among previously uncharacterized deep-sea hydrothermal vent communities.

TL;DR: The objective is to create a fully global, top-to-bottom, dynamically complete, and multidisciplinary Argo Program that will integrate seamlessly with satellite and with other in situ elements of the Global Ocean Observing System.

TL;DR: In this paper, a survey of the current field over the South Scotia Ridge, obtained with a lowered Acoustic Doppler Current Profiler (LADCP), is presented, which suggests that a significant proportion of the Antarctic Bottom Water (AABW) invading the world ocean abyss escapes the Weddell Sea via the Scotia Sea.
