Objectives

SWINGS is a multidisciplinary 4-year project dedicated to elucidate trace element sources, transformations and sinks along a section crossing key areas of the Southern Ocean. Major French contribution to the international GEOTRACES program (www.geotraces.org), SWINGS involves around 80 scientists (21 international laboratories, 7 countries). As core action of SWINGS, the SWINGS cruise started from La Reunion on January 11th 2021 and ended at La Reunion 57 days later on March 8th, 2021. This cruise explored a large part of the South Indian Ocean in order to tackle the following objectives

1. Establish the relative importance of sedimentary, atmospheric and hydrothermal sources of TEIs in the Indian sector of the Southern Ocean
2. Investigate the drivers of the internal trace element cycles: biogenic uptake, remineralization, particle fate, and export, and
3. Quantify TEI transport by the Antarctic Circumpolar Current
