Southern Ocean

Tasman Boundary Conditions Voyage TAN0609 was a NIWA (New Zealand) lead cruise focusing on the Tasman Sea. More information can be found from the cruise report.

SAZ-SENSE is a study of the sensitivity of Sub-Antarctic Zone waters to global change. A 32-day oceanographic voyage onboard Australia's ice-breaker Aurora Australis was undertaken in mid-summer (January 17 - February 20) 2007 to examine biogeochemical processes in SAZ waters west and east of Tasmania, and also in the Polar Frontal Zone south of the SAZ. The strategy is to compare low productivity waters west of Tasmania (areas with little phytoplankton) with higher productivity waters to the east, with a focus on the role of iron as a limiting micro-nutrient.  This cruise was part of the GEOTRACES IPY programme. See the metadata form for more information.

The Sea Ice Physics and Ecosystem eXperiment (SIPEX) is one of Australia's major contributions to the International Polar Year (IPY). The expedition explored the sea ice zone around Antarctica in September - October 2007 and investigated the relationships between the physical sea ice environment and the structure of Southern Ocean ecosystems. See the cruise report and the metadata form for more information.

MD166 Bonus Good Hope Cruise. Sailed in 2008 aboard the Marion Dufresne. This cruise was part of the international IPY programme and GEOTRACES was one of the main projects associated with the cruise. Details can be found in the cruise report.

ANTXXIV-3 Zero and drake. Sailed in 2008. See the cruise report for further details.

Australian-led voyage aboard Aurora Australis, organised by the Antarctic Climate and Ecosystems Cooperative Research Centre, followed the 'SR3' transect along approximately 140°E, between Tasmania and the coast of Antarctica. This transect has been well characterised oceanographically in the past two decades. The results of this work will yield the first synoptic, circumpolar measurements of micronutrient trace elements in the Southern Ocean. Dissolved iron data along the SR3 transect represent an order of magnitude improvement in sampling resolution and show widespread iron limitation in upper ocean waters along the transect. See the voyage report for more information.
