This paper is a review article that stemmed from a debate within the Southern Ocean community. The paper explains how “fronts”, sharp boundaries between water masses, are defined, and what their effects might be on the biology of the Southern Ocean.

Climate models project that all circulation features of the South Indian Ocean, including the Leeuwin Current and Undercurrent, North and South East Madagascar Currents, transport through the Mozambique Channel and Agulhas Current are projected to weaken significantly in the last half of the 21st century with unchecked greenhouse gas emissions.

The Montreal Protocol, an international agreement signed in 1987 to stop chlorofluorocarbons (CFCs) destroying the ozone layer, now appears to be the first international treaty to successfully slow the rate of global warming.

Turning on a magnetic field may make fluids that conduct electricity behave more like honey than like water. This discovery may help explain a mystery of Jupiter’s zonal winds, the alternating east-west jet streams, seen in photographs as colourful stripes.

Solar heating of surface waters in the tropical Indian and Pacific oceans, along with turbulent mixing that moves this heat into the colder deep-reaching Atlantic meridional overturning circulation, play a crucial role in shaping oceanic heat transport pathways

CLEX researchers investigate the physics of the Antarctic Circumpolar Current to understand why increased wind stress doesn’t lead to a more powerful current. It turns out the ocean floor plays a key role.

This study found in CMIP5 models that are able to simulate both types of events, that convective extremes do not always coincide with warm extremes. The disassociation becomes more distinct under greenhouse warming with higher occurrences of convective extremes than warm extremes.

The energy of vortices in the Southern Ocean has increased over the past two decades due to an increase in the mean amplitude of the vortices rather than an increase in their number.

A known weakness of the Ensemble Kalman filter approach is that its ability to provide state estimates that closely match densely distributed observations is very limited. This paper describes a computationally inexpensive innovative variation on the technique that greatly ameliorates this difficulty.
