| Section | Country | Funding | Information | Data |
|---|---|---|---|---|
| GIpr01 | France | Funded | KEOPS2 (Kerguelen Ocean and Plateau compared Study) sailed in August 2011, with the aim of investigate natural Fe fertilisation of the Southern Ocean. Results from past studies (KEOPS1 and CROZEX) have raised new questions which will be focus of KEOPS2. |
|
| GPpr01 | New Zealand | Funded | FeCyclesII sponsored by NIWA New Zealand (Chief Scientist P.Boyd) investigated the natural cycling of micronutrient iron and other trace elements in relation to carbon and nutrient biogeochemistry, more information is provided in the metadata form. |
|
| GPpr02 | Australia |
Funded | PINTS – primary Productivity induced by Nitrogen and Iron in the Tasman Sea. This research voyage studied iron bioavailability, sources and its biogeochemical cycling in the surface waters of the Tasman Sea, other trace metals that can act as co-limiting factors on primary productivity were also measured. Results from this voyage will thus improve our understanding on the parameters controlling primary productivity in the Tasman Sea and the biological response to relevant climate change scenarios. See voyage summary for more details. |

| GIpr02 | Australia | Funded | SIPEX 2: Sea Ice Physics and Ecosystem eXperiment 2, Chief Scientists: Tony Worby/Klaus Meiners (AAD, Australia). The expedition will be aboard Australia's icebreaker RV Aurora Australis in the region of East Antarctica west of 110°E (64-65°S). Sea ice is a structuring component of the Southern Ocean and plays a pivotal role in the biogeochemical cycles of Antarctic marine ecosystems. The SIPEX-2 expedition will explore the sea ice zone around Antarctica and will investigate relationships between the physical sea ice environment and the structure of Southern Ocean ecosystems. The main objectives of the project are: • To identify how biological primary and secondary productivity is affected by winter sea ice extent and properties, and by ocean circulation • To obtain large-scale information on sea ice biological (sea ice algae distribution and under-ice krill distribution) and physical parameters (sea ice thickness distribution, under-ice velocity field) • To obtain biogeochemical data on sea ice with a special focus on the trace metal biogeochemistry in sea ice. |

| GApr02 | Poland | Funded | Oceania 15/2011 - The
first GEOTRACES process study in the Baltic Sea was completed in November 2011on the R/V OCEANIA, PI:
Prof. Jacek Beldowski (IOPAS). The objective of this cruise was
to sample the major fresh water input sources of TEIs to the central Baltic, to
obtain high resolution profiles of TEIs across the redox cline at the central
Baltic anoxic deep basins, and to sample the exchange with the western Baltic
through surface export and the only deep channel permitting salt water inflow.
The expected outcome of this study is the identification of sinks and sources of
TEIs in marginal seas and an understanding of relevant processes governing the
export and import fluxes, particularly their modification by redox cycling in
the water column. It is planned to conclude the study of Baltic Sea exchange
with the Atlantic with a follow up cruise to the western Baltic Sea and into the
North Sea. See voyage summary for more details. |
