Observing and Understanding the Ocean below Antarctic Sea Ice and Ice Shelves (OASIIS)


While changes in the Southern Ocean have widespread consequences for the planet, the paucity of observations in this part of the ocean hinders research. The OASIIS working group aims to develop a detailed implementation plan for an under-ice observing system. This truly global consortium led by Richard Coleman, the Institute for Marine and Antarctic Studies, University of Tasmania, has members from the UK, US, Australia, Germany, China, South Africa and Sweden.

How OASIIS contributes to POGO priority areas

POGO advocates for a global coverage in the ocean observing system, which is why addressing the imbalance of available observation systems between the northern and southern hemisphere is at the heart of the POGO Strategy. OASIIS is aiming to make use of the global network that POGO offers to develop transformative technologies that could greatly advance under-ice observations, by bring together expertise, capabiltites and capacity of leading ocean science and technology institutions.

The high latitude Southern Ocean and Antarctic margin includes several physical environments (1-5), each with distinct characteristics that mean a different mix of platforms is needed to observe each one. 1: Open ocean shallower than 2000m depth, 2: Deep ocean, 3: Continental shelf and slope, 4: Ice shelf cavities, 5: Sea ice and ice-ocean-atmosphere interaction (from “Seeing Below the Ice: A strategy for observing the ocean beneath Antarctic sea ice and ice shelves”, 2014, SOOS report, 57 pp).
