Three GEOTRACES cruises will be sailing simultaneously in the Atlantic, the Pacific and the Southern Ocean

Three national GEOTRACES programmes (Japan, UK and South Africa) will undertake GEOTRACES cruises in the coming months. The first cruise to leave port will be the Japanese cruise along the GEOTRACES Pacific section GP02. This section cruise will depart from Tokyo (Japan) on 23 June and arrive port in Vancouver (Canada) on 7 August. During the cruise, biogeochemical cycles of trace elements and isotopes (TEIs) will be investigated in the High-Nutrient, Low-Chlorophyll (HNLC) areas of the subarctic North Pacific and the Gulf of Alaska (see figure below).

The UK ZIPLOC cruise will sail in the tropical Atlantic Ocean. It will depart on 27 June from Guadeloupe (French overseas region) and return port on 13 August in Tenerife (Canary Islands). This cruise has been endorsed as GEOTRACES process study and it will investigate zinc, iron and phosphorus co-limitation in the ocean.

The South African GEOTRACES cruise on board the research vessel Angulhas II will depart from Cape Town (South Africa) on 29 June. During 15-days this GEOTRACES process study will navigate in the Indian sector of the Southern Ocean (30˚E line, see figure below) to study the sources, sinks and cycling of bioactive trace elements as well as the impact of the hydrothermal ridge on trace metal distribution and speciation.

  • UK cruise chief scientist: Claire Mahaffey  (GEOTRACES scientists: Maeve Lohan and Alessandro Tagliabue)
  • South African cruise chief scientist: Marcello Vichi (GEOTRACES scientist: Alakaendra Roychoudhury)

GEOTRACES paper selected as NOAA-Office of Oceanographic and Atmospheric Research paper of the year

15 Nature cover

Congratulations to Joseph Resing and co-authors whose paper "Basin-scale transport of hydrothermal dissolved metals across the South Pacific Ocean" (2015, see reference below) was selected for a NOAA-Office of Oceanographic and Atmospheric Research paper of the year award. This paper published in Nature reports findings from the US East Pacific Zonal Transect (EPZT) GEOTRACES cruise (GP16).

The paper was featured on the cover of Nature (Volume 523 Number 7559, Thursday 9 July 2015). A GEOTRACES science highlight of the paper is available here.

Postdoc in contaminants transport modelling in coastal area, Toulon University, France

Employer: Toulon University - MIO and PROTEE laboratories (,

Job location: La Garde (France)

Duration: 18 months - Expecting starting: 1st september 2017 - Salary: ~ 2000€ / month

Deadline for application: June 30th 2017

Job description: In the framework of the Interreg Marittimo IMPACT project (2017-2020, European Union funding), coordinated by ISMAR/CNR (Italy), MIO and PROTEE laboratories from Toulon University (France) are opening an 18-months post-doc position. Gathering the competences from Italian and French research partners, the IMPACT project aims at better understanding the influence of large harbors onto Marine Protected Areas, along the Italian and French Mediterranean coasts. In particular, MIO and PROTEE laboratories will be in charge of coastal circulation (through physical observation and numerical modelling) and the assessment of inorganic contaminants (trace elements) levels in the main environmental compartments (water column, sediments) from such confined environments. In such context, the recruited post-doc will have to adapt modelling approaches in order to simulate the distribution, transport and fate of contaminants in coastal environments. Among the 4 areas selected in the IMPACT project, this offer will mainly focus on the study of the Toulon Bay (France) and surrounding Marine Protected Area (Parc National de Port Cros), as a case study particularly affected by anthropogenic pressures. On field physical and chemical data collection will be part of the proposed tasks. Most of the job will be conducted at Toulon University, along with few field campaigns and meetings in Italy and Corsica with the other involved partners. MIO and PROTEE laboratories are seeking for a candidate having either (1) a strong background in ocean numerical modelling with experience in (bio)geochemistry of trace elements and/or contaminants, or (2) a strong background in marine (geo)chemistry of trace elements and/or contaminants with experience in numerical modelling. This position being in the framework of an international research project, a PhD is requested as well as fluent English capacity. Additional experience as a post-doc is welcomed together with field campaign ability.

To apply for this position: detailed CV, motivation letter and at least 2 references to Dr. Yann OURMIERES and Dr. Cédric GARNIER (,

GEOTRACES intercalibration cruise for mercury species in seawater

A GEOTRACES intercalibration cruise for mercury species in seawater will be held from 11 to 23 June 2017. During that time, 6 daily cruises in the Northwestern Mediterranean Sea will be conducted on res
earch vessel Anthedon II. 23 scientists of 13 international Hg teams will sample a coastal – open ocean gradient using a trace clean rosette with 12 Go-Flo bottles and 4 McLane in situ pumps. Samples will be brought back to the Mediterranean Institute of Oceanography and analyzed in clean conditions within hours after sampling. We will also fill 1500 pre-combusted 100 mL glass bottles to develop a GEOTRACES Hg reference material. This intercalibration cruise is build on the previous intercalibration exercises within GEOTRACES (2008, 2009, 2011, 2013, 2014, 2015), and those before, and will be essential for the intercalibration of all Hg species for the GEOTRACES intermediate data product (IDP).

Chief scientist: Lars-Eric Heimbürger (Mediterranean Institute of Oceanography, France)

Postdoctoral Research Associate in Quantitative Ocean Biogeochemistry at the University of Liverpool, UK

Postdoctoral Research Associate in Quantitative Ocean Biogeochemistry at the University of Liverpool - £32,958 - £38,183

We are looking to appoint an ambitious and creative individual in the broad field of ocean biogeochemistry and phytoplankton physiology. Our research group is interested in understanding how bio-essential resources are cycled in the oceans and how their availability affects phytoplankton physiology and vital rates. This particular post is linked to an exciting European Research Council project led by Dr Alessandro Tagliabue concerned with expanding our understanding of what shapes the magnitude and variability in biological activity in the ocean ( The exact nature of the position is open to be developed in line with your interests, skills and future ideas, but will have strong links to the impact of micronutrients on phytoplankton activity using quantitative tools.  You will come with your own research ideas, but also operate as part of a wider team of researchers concerned with similar questions within the research group. In particular, the project has a strong set of national and international collaborators with whom you will be able to interact with. There is funding to support your travel to collaborators laboratories and to present our results at key international conferences.  The post is available until 30 September 2019.
