Forthcoming departure of the Australian SR3-GEOTRACES section voyage in the Southern Ocean

SR3-GEOTRACES 2018 is an Australian led research expedition along the SR3 line (approximately 140ºE) from Hobart (Tasmania, Australia) to the Antarctic ice-edge. The goal of the SR3-GEOTRACES expedition is to determine the distributions of trace metals and isotopes (TEIs), their change with time, and the physical, chemical and biological processes controlling those evolving distributions. During 6 weeks, scientists will measure TEIs, nutrients, the carbon system and ocean physics along the SR3 section. Measurements of TEIs are scarce in the Southern Ocean, particularly on repeat sections and in deeper waters. TEI distributions on the SR3 line will be compared to expeditions in spring 2001 and late autumn 2008 to assess seasonal and longer-term changes.  The section will also sample for TEIs in marine particles, and stable, radioactive and radiogenic isotopes that have not been measured before in this sector of the Southern Ocean. We will also sample for TEIs in aerosol particles, and metagenomic analyses will be used to characterise the structure and function of the microbial community as a function of latitude and depth along the repeat transects.

The SR3-GEOTRACES voyage aboard the RV Investigator will depart from Hobart (Australia) on 10th January 2018 and return back to Hobart on 21st February 2018, and will include 40 scientists and technical support staff from 6 nations. The voyage will sail along the GEOTRACES International section GS01 (please see cruise track below). The expedition will also include projects on ocean physics and carbon cycling along SR3, together with the CAPRICORN project evaluating satellite cloud, aerosol, precipitation, and surface flux products over the Southern Ocean.

Upcoming departure of the U.K. FRidge cruise in the Atlantic Ocean

FRidge is a U.K. led research expedition to the Mid-Atlantic Ridge which will explore hypotheses regarding the mechanisms that shape the ocean iron distribution. In particular, it will study the role of hydrothermal inputs from distinct vent sites along the ridge.

The FRidge cruise aboard the RRS James Cook will depart from Southampton (UK) on 20th December 2017 and arrive port in Guadeloupe (France) on the 1st February 2018. The cruise will sail along the GEOTRACES International section GA13 (see cruise track below).

During 6 weeks scientists will measure trace metals, nutrients and ocean physics over and around the mid Atlantic ridge in order to:

  • Document the distributions of trace metals in the North Atlantic Ocean and how they vary on and off the Mid-Atlantic Ridge;
  • Examine the mechanisms driving the magnitude of hydrothermal trace metal plumes at different hydrothermal sites along the Mid-Atlantic Ridge.

Save the date! Joint GEOTRACES/PAGES Workshop



Trace element and isotope proxies in paleoceanography:
A synthesis workshop

3 – 5 December 2018, Aix-Marseille, France


: The joint GEOTRACES/PAGES workshop on the synthesis of geochemical proxies used in paleoceanography aims to establish the strength, limits and conditions of application of a given proxy. 
There is a vital need for a synthesis of geochemical proxies used in paleoceanography to improve interpretation of commonly used proxies. This synthesis is timely in view of the wealth of new data coming from GEOTRACES and contemporary programs. The workshop will bring together expertise from GEOTRACES, PAGES, and the broader oceanographic community of observationalists and modellers that will exploit new data to provide a more rigorous calibration of proxies and interpretation of their records.

Working groups
Biological productivity / Oceanic circulation / Particle flux and sedimentation rate / Physical and/or biogeochemical modelling.

 PAGES, GEOTRACES, SCOR, US-NSF, CNRS-INSU-LEFE, Aix-Marseille Université, Thermo Fisher Scientific and John Cantle Scientific.

More information
 will be available in early 2018. For any questions, please contact: Kazuyo Tachikawa ( or Laurence Vidal (

We look forward to seeing you at the workshop.
