Cruise details

Section	Country	Cruise Dates (completed cruises/ approved future cruises)	Information
GI04	Japan	06-11-2009 — 10-01-2010	Cruise KH-09-5 legs 1, 2 and 3 sailed in November 2009 on the Japanese ship RV Hakuho Maru. The cruise aimed at precise and detailed measurements of trace elements and isotopes in the Indian Ocean. Atmosphere and bottom sediment samples were collected to help identify processes and fluxes that control the distribution of trace elements in water columns, and to elucidate their important linkage with global climatic change. Please consult the preliminary cruise report for further information or contact Dr Toshitaka Gamo (Chief Scientist and GEOTRACES Scientist). For further details on parameters sampled on the cruise and other relevant metadata please see the GEOTRACES pre-cruise metadata form.
GI08	Still to be decided	Still to be decided	India to Antarctica.
GIPY01	New Zealand	12-07-2006 — 01-08-2006	Tasman Boundary Conditions Voyage TAN0609 was a NIWA (New Zealand) led cruise focusing on the Tasman Sea. focusing on the Tasman Sea, departing and returning from Wellington port, New Zealand with Dr Philip Sutton as the Chief Scientist. Professor Philip Boyd was the GEOTRACES Scientist. More information can be found in the cruise report. For further details on parameters sampled on the cruise and other relevant metadata please see the GEOTRACES post-cruise metadata form.
GIPY02	Australia	17-01-2007 — 20-02-2007	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 with Dr Brian Griffiths as the Chief Scientist and Dr Andrew Bowie as the GEOTRACES Scientist. 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 formed part of the GEOTRACES IPY programme. Please consult the GEOTRACES post-cruise metadata form for more information on parameters sampled.
GIPY03	Australia	03-09-2007 — 17-10-2007	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. The Chief Scientist on board was Dr Anthony Worby and the GEOTRACES Scientist Dr Andrew Bowie. Please see the cruise report and GEOTRACES post-cruise metadata form for more information.
GIPY04	France	08-02-2008 — 24-03-2008	The 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 this cruise. The Chief Scientist on board was Professor Sabrina Speich and the GEOTRACES Scientist Dr Marie Boye. Details can be found in the cruise report and the GEOTRACES post-cruise metadata form.
GIP05	Germany	06-02-2008 — 16-04-2008	ANTXXIV-3 Zero and Drake was a German cruise which departed Cape Town in South Africa and returned to Punta Arenas, Chile from February to April 2008. The Chief Scientist on board was Dr Eberhard Fahrbach and the GEOTRACES Scientist Professor Hein J.W. de Baar. Please see the cruise report and the GEOTRACES post-cruise metadata form for further details.
GIPY006	Australia	22-03-2008 — 17-04-2008	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. The Chief Scientist was Dr Stephen Rintoul and the GEOTRACES Scientist Dr Edward Butler. Please consult the voyage report for more information. For further details on parameters sampled and other relevant metadata please see the GEOTRACES post-cruise metadata form.
GIPY08	Spain	2009-01-23 — 2009-03-03	ATOS-2 cruise is part of the International Polar Year (IPY) cruises. ATOS-2 set sail from Punta Arenas, Chile to Antractic Peninsula and back to Ushuaia, Argentina from 23 January to 03 March 2009. The cruise sampling for GEOTRACES key elements started in the Weddell sea and continued to the west coast of the Antarctic Peninsula through the Brandsfield strait. Dr Duarte Carlos was the Chief Scientist of the cruise and Dr Tovar-Sánchez Antonio was the GEOTRACES Scientist.
GS01	Australia	2018-01-11 — 2018-02-21	IN2018_V01 (GS01) cruise took place along 140°E (the SR3 line) from 11 January 2018, 21 February 2018 (starting from Hobart). Dr Andrew Bowie was the GEOTRACES Scientist. For further details sampled on this cruise please see the GEOTRACES post-cruise metadata form.
GS02	France	Still to be decided	SWINGS (South West Indian Geotraces Section) cruise proposal was submitted (PIs Dr Jeandel Catherine and Dr Planquette Helen). SWINGS is expected on the RV Marion-Dufresne for 2019-2020.
GS03	Australia	Still to be decided	Perth to Kerguelen following WOCE I05 line west of Australia.
GS04	Still to be decided	Still to be decided	This section was proposed during the Indian Ocean Geotraces workshop.
GS05	Germany	Still to be decided	Dr Katharina Pahnke will be the Chief Scientist on this South East Indian Ocean cruise.
