Job opportunities

Postdoctoral Research Associate - Marine Chemistry at The University of Southern Mississippi


The USM Division of Marine Science seeks a highly motivated postdoctoral researcher to participate in projects related to both submarine groundwater discharge as well as open ocean dissolved trace element distributions. Candidates must have a Ph.D. in oceanography or related field, with emphasis on geochemical processes. Candidates must have demonstrable experience doing geochemical research in the field as well experience in geochemical analysis. They must possess demonstrable experience in conducting science with peer-reviewed publications. Experience doing radionuclide and/or trace element research is preferred.

The position is funded by grants to Dr. Alan Shiller; work in our lab involves a variety of projects relating to studies of submarine groundwater discharge in the northern Gulf of Mexico, GEOTRACES studies of dissolved trace elements in the Pacific Ocean, and testing of new ocean chemical sensors.

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: http://bit.ly/2xGpE45

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). 

LOCATION: ROYAL NIOZ TEXEL (THE NETHERLANDS)
VACANCY ID: 2019 - 30
CLOSING DATE: 07th of September 2019

Information can be found here : https://www.workingatnioz.com/our-jobs/postdoc-in-marine-trace-metal-and-isotope-biogeochemistry.html

THE RESEARCH

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.

THE PROJECT

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.

THE CANDIDATE

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.
