GEOTRACES Activities in Sweden during 2010
The Swedish GEOTRACES activities during 2010 comprise four major themes i) proposal and planning activities for a GEOTRACES project in the Arctic; ii) Participation in intercalibration efforts; iii) Participation in COST action ES0801; iv) GEOTRACES related activities in other projects/cruises.
Planning work related to GEOTRACES
Building upon the outcome of the Delmenhorst Arctic planning workshop a proposal has been submitted to the Swedish research council (VR) with the aim to use the icebreaker Oden as a research vessel for a GEOTRACES cruise in the Arctic Ocean (PI Per Andersson). The proposal was graded excellent and adopted for initial planning by Swedish Polar Research Secretariat (SPRS), see enclosed list of prioritised Arctic and Antarctic projects. The proposal includes international collaboration and the time frame for the proposed cruise is by the end of the coming 5 year period.
Participation and presentation (Per Andersson) of the Swedish Arctic GEOTRACES plans at the US GEOTRACES Arctic Workshop, 29 Sept. to 1 Oct., 2010, at NSF headquarters in Washington DC.
Robert Anderson was invited by the Royal Swedish Academy of Sciences (KVA) for a lecture in Nov. 2010. During his visit a presentation of GEOTRACES and the Swedish Arctic plans was made for the KVA geoscience class. Also a meeting between Bob A., SPRS and Per Andersson was undertaken where possible collaboration US-Swedish collaboration was discussed.
COST action ES0801
Within the COST action the ocean chemistry of bioactive trace elements and paleoclimate proxies Swedish scientist are participating in the following during 2010:
• The test and training cruise organised by Dutch researcher on R/V Pelagia from Texel to Iceland 22 to 28 April, 2010. Unfortunately the trip was cancelled due to the Icelandic volcanic ash over European air space.
• Swedish participation (Johan Ingri) in planning workshop during 2011 for planning Baltic Sea cruises
GEOTRACES intercalibration work
Swedish laboratories participated in the intercalibration effort of Nd, Th and Si isotopes and some trace elements. Results have been reported to the coordinators for each element. Participation in the GEOTRACES intercalibration workshop at ODU Norfolk VA, 8 to 10 March 2010.
Funding
Some supporting funds for the GEOTRACES IPO have been secured and transferred to the IPO in Toulouse.
GEOTRACES promotion activities within Sweden
• Per Andersson rotated off the GEOTRACES SSC at the end of 2010 and David Turner, Gothenburgh University, is a new SSC member from 2011. Per and David met in March 2011 for a discussion about GEOTRACES.
• An e-mail list is kept and maintained by P Andersson for distribution of information about the GEOTRACES project among marine scientists in Sweden. This list is now transferred to David Turner.
• Presentations of the GEOTRACES project for the Swedish Geophysical Committee at KVA and the Swedish SCOR group meeting in March 2010.
Cruises, projects and publications
Amundsen Sea Polynya International Research Expedition (ASPIRE). A joint US-Swe expedition on icebreaker Oden and R/V Palmer during 2010/2011 with GEOTRACES related activities. Participation in TEI projects from Stockholm University (Kuria Ndungu) and Swedish Museum of Natural History (Per Andersson).
Presentations of results from the Amundsen Sea cruises at OSM in Portland Oregon, February 2010. Abstract of presentation:

Climate warming in Siberian Permafrost Regions; tracing the delivery of carbon and trace metals to the Arctic Ocean. This project (PI's P Andersson and D Porcelli, Oxford) was funded by the VR as a three year project (2011-2013) and includes a field study in the Lena River Basin planned to take place during 2012. The main aim is to study a large basin dominated by permafrost and the impact of changing temperatures on the delivery of TEI to the Arctic Ocean.
