KEOPS 2 (Kerguelen Ocean and Plateau compared Study) sailed in October 2011, with the aim of investigating the impact of natural Fe fertilisation on biogeochemical cycles in the Southern Ocean. Results from past studies (KEOPS1 and CROZEX) have raised new questions which have been focused on in this study. Please refer to the cruise report for further information or contact Dr Stephane Blain (Chief Scientist) or Dr Catherine Jeandel (GEOTRACES Scientist)

SIPEX-2: The second Sea Ice Physics and Ecosystem eXperiment with Chief Scientists Dr Tony Worby and Dr Klaus Meiners (AAD, Australia). The GEOTRACES Scientist was Dr Andrew Bowie. The expedition took place 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, as well as 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 and under-ice velocity field)
  • To obtain biogeochemical data on sea ice with a special focus on the trace metal biogeochemistry in sea ice.

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 further information or contact the Chief Scientist Dr Christel Hassler/ GEOTRACES Scientist Dr Michael Ellwood.

SO245 (UltraPac) is currently taking place in the ultra-oliogotrophic south Pacific gyre on RV Sonne. This cruise departed from Antofagasta in Chile and will return to Wellington in New Zealand.

Due to its extreme remoteness from any continents, surface waters of the South Pacific Subtropical Gyre (SPG) are the most oligotrophic in the global ocean, with the clearest waters and lowest sea surface chlorophyll a concentrations. This area is poorly studied. Recent studies indicate that microbial nutrient and carbon cycling is especially adapted for these ultraoligotrophic waters, and SPG may be a significant region of nitrogen fixation. Paradoxically, relatively large concentrations of dissolved organic carbon and dissolved organic nitrogen exist in these waters. This cruise will undertake a cross-gyre transect to determine the controls on nitrogen, phosphorus and organic carbon cycling in the surface waters, both in the dark pelagic zone and surface sediments. The role of particle & dust input and the distribution of Nd isotopes to further characterise the SPG water masses will also be investigated.

Please contact Dr Timothy Ferdelman or Dr Katharina Pahnke for more details if required. The GEOTRACES pre-cruise metadata report can be access here.

Oceania 15/2011 was the first GEOTRACES process study in the Baltic Sea to be completed in November 2011 on the RV Oceania. The Chief Scientist on this cruise was Professor Jacek Beldowski (Polish Academy of Sciences Institute of Oceanology) and the GEOTRACES Scientist Professor Michael Staubwasser.

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 was 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. Please see the voyage summary for more details.

These 3 cruise legs are part of the NERC Shelf Sea Biogeochemistry (SSB) programme and investigate the supply of iron from shelf sediments to the ocean.

The leading Scientist on DY018 was Professor Jonathan Sharples with Professor Maeve Lohan appointed as second point of contact. This leg of the cruise departed from Falmouth, UK and returned to Southampton, UK. Please see the GEOTRACES post-cruise metadata form for further information on this cruise leg.

The Chief Scientist on the DY029 leg was Dr Alex Poulton. The RRS Discovery set sail and returned to Southampton, UK. A GEOTRACES post-cruise metadata form is available to view for more details.

The Chief Scientist on the DY033 leg was Professor Mark Moore. The RRS Discovery set sail and returned to Southampton, UK. A GEOTRACES post-cruise metadata form is available to view for more details for this leg of the cruise.

Please contact Professor Maeve Lohan if you require information about any of the above cruise legs.

All 3 legs of this cruise utilise trace metal clean sampling techniques with associated physical diffusion and advection measurements to determine the supply of dissolved, colloidal and particulate forms of iron from sediments and their subsequent fate in shelf sea waters and during export to the North Atlantic Ocean. Radium isotopes will also be used to determine the flux of iron from the shelf to the open ocean.

The 64PE401 (Fe Vici) cruise set sail on 31 August from Istanbul in Turkey and returned to Varna, Bulgaria on 17 September 2015. The aim was to gain insight into the mechanisms and rates of iron release from sediments on the northwestern shelf of the Black Sea, and the lateral transport of iron and other trace metals over the shelf to the adjacent anoxic basin. The relationship between the release of sediment iron and changes in bottom water oxygen concentrations as well as the role of bioirrigating fauna for iron release were of specific interest. The Chief Scientist on board the RV Pelagia was Professor Caroline Slomp, of whom should be contacted if further information is needed. The GEOTRACES pre-cruise metadata form can also be viewed here. No information on this form requires updating post cruise as nothing changed whilst the cruise was taking place.

 

The 64PE411 cruise will set sail on 27 May from Nynashamn, Sweden and anticipates to return to Texel in the Netherlands on 15 June.

The aim of this cruise is to gain insight into the mechanisms and rates of iron release from sediments in the Baltic Sea, as well as the lateral transport of iron (and other trace metals) over the shelf to the adjacent anoxic basin. The scientists are specifically interested in (1) the relationship of sediment iron release with changes in bottom water oxygen concentrations; (2) the role of bioirrigating fauna for iron release; and (3) the role of Fe-CH4 interactions.

The Chief Scientist on board the RV Pelagia will be Professor Caroline Slomp. For further information regarding this cruise please contact Caroline, or access the pre-cruise metadata form.
