Recommendations for nations developing a trace metal-clean sampling system

A extremely useful resource for nations developing trace metal-clean sampling systems is now available on the GEOTRACES web site!

Based on 11 years of experience, Greg Cutter, GEOTRACES Standards and Intercalibration past co-chair, has summarised the recommendations that nations developing a trace metal-clean sample system need to consider for successful sampling.

The document available here includes essential information as a description of the existing sampling systems, provide useful advise on the purchase of the sampling bottles, guide in the clean lab design, etc. In other words a valuable source for those willing to do GEOTRACES research.

Lab Manager at Old Dominion University, Virginia, USA

We are seeking a highly motivated individual to join Greg Cutter’s research team in the Department of Ocean, Earth, and Atmospheric Science at Old Dominion University. Our laboratory conducts chemical oceanography research around the globe and is associated with the international GEOTRACES program, a global effort to understand biogeochemical cycles and distributions of trace elements in the marine environment. The Lab Manager is responsible for overall operation of the laboratory, performs determinations of trace elements, nutrients, and other trace constituents, and supervises undergraduate lab assistants and other technicians, and assists the graduate research assistants. Must have analytical experience with at least some of these constituents and have participated in oceanographic sampling expeditions. Applicants should have a M.S in chemistry, oceanography, or related environmental science with at least 1-2 years of analytical laboratory and field work experience. Applications must be submitted by 5 August 2019 and the Position can start as early as 1 September 2019. Further information and apply at:

Postdoc in Marine Trace Metal and Isotope Biogeochemistry, Royal NIOZ Texel, The Netherlands

The Department of Ocean System Research (OCS) is looking for a highly motivated post doc with a background in marine trace metal biogeochemistry and with an interest in the cycling of iron and iron isotopes as well as other bio-active metals (Principal investigator dr. Rob Middag). 

VACANCY ID: 2019 - 30
CLOSING DATE: 07th of September 2019

Researchers in the Department Ocean System Research (OCS) study open-ocean processes from a variety of disciplines, ranging from physical and chemical oceanography, marine geology, paleoceanography to deep-sea ecology. We investigate the oceans in the past and present, to assess their future role. We make use of experiments and data collection during sea-going oceanographic research, as well as laboratory experiments and analyses in our home base on Texel. The department works around the globe, from the Antarctic to the Arctic, from the Caribbean to the North Sea. One of the areas we work in is the North Atlantic Ocean.

Researchers within OCS focus on the biogeochemical cycles of trace elements and their isotopes (TEI’s) in the global ocean and are active in the International GEOTRACES programme. Many trace elements are essential for marine life and as such influence ocean ecosystems and the global carbon cycle. Advances in sampling and innovative analytical techniques make it possible to study the cycles of TEI’s at unprecedented scale and in ever more detail. Specifically for iron, it is not only apparent that this micro-nutrient plays a pivotal role in the ocean, but also that the cycle of iron is changing due to ongoing climate change. However, our current understanding of the marine iron cycle still does not allow reliable biogeochemical modelling to predict and evaluate the consequences of these changes. Particularly processes such as biological metal uptake, remineralisation and dissolved-particle interactions in both the water column and benthic boundary layer are not sufficiently understood, nor the susceptibility of these processes to change.


This project is part of the NWO Vidi grant recently awarded to Rob Middag, “Trace metals and the Arctic-Atlantic gateway in a changing world, local processes and global connections (MetalGate)”. In this project we will investigate the cycling of iron and its isotopes as well as other bio-active metals in the Greenland-Iceland-Norwegian-Sea region, the main gateway between the Arctic and Atlantic Ocean. We will combine trace metal and isotopic measurements with temperature controlled bio-assays at ecologically relevant conditions and develop sampling techniques to study the processes and interactions in the benthic boundary layer.

The project will be focused around an expedition aboard our research vessel ‘Pelagia’ to the high latitude North Atlantic and the seas surrounding Iceland where we will use the NIOZ Titan sampling and CTD system for trace metals as well as state-of-the- art temperature controlled deck incubators. Prior to the expedition, a new trace metal clean sampler for sampling of the benthic boundary layer will be developed and tested together with experienced NIOZ technicians. The expedition will be a GEOTRACES process study and various international collaborators will be involved.


We are looking for a highly motivated candidate with a PhD in chemical oceanography or a related area with proven ability to publish research in international peer reviewed journals. You have experience in marine trace metal sampling and analysis, and experience with iron isotope analysis is of advantage. Participation in an oceanographic research expedition is an essential part of the project and due to the international character of the research team, it is crucial you are proficient in spoken and written English.

Your position will be hosted by the Department of Ocean Systems (OCS) at the Royal NIOZ on the isle of Texel.

PhD opportunity, Hebrew University of Jerusalem, Israel

Research position for an MSc/PhD student is available to study Interactive mechanisms of mineral dissolution by a microbial consortia

Essential metabolic functions within ecosystems are often partitioned among various members of microbial communities that each benefit the whole population. In this study, we aim to elucidate the genetic and molecular basis of a symbiotic relationship between heterotrophic bacteria and a photosynthetic marine diazotroph, Trichodesmium. The research involves computational analysis of omics experiments (bioinformatics) and will be centered in Haifa and Jerusalem, Israel

New positions at the University of Tasmania, Australia

There are a number of new academic and professional positions available in Hobart (Australia) under the Australian Antarctic Program Partnership.

The University of Tasmania is pleased to host the operation and activities of the Australian Antarctic Program Partnership (AAPP) – a new research program funded through the Antarctic Science Collaboration Initiative of the Department of Industry, Innovation and Science. The AAPP brings together government and non-government entities to deliver and lead a significant part of the national Antarctic science program. The partnership includes the University of Tasmania (UTAS), the Australian Antarctic Division (AAD), CSIRO Oceans and Atmosphere, Geoscience Australia, the Bureau of Meteorology (BoM), the Tasmanian State Government and Australia’s Integrated Marine Observing System (IMOS).

The AAPP will carry out research to understand the role of the Antarctic region in the global climate system and the implications for marine ecosystems, by enabling collaborative research aligned with the Australian Antarctic Science Strategic Plan and Australian Antarctic Strategy and 20 Year Action Plan. 

Please see here for full listings:

Applications close either 13 or 23 June.
