Postdoctoral position in trace metal biogeochemistry in the South Indian Ocean as part of the International GEOTRACES Programme

starting on July 1st, 2020.

Project Description

A research cruise with FS Sonne is scheduled for July-August 2020 in the South Indian Ocean (SIO) from Durban (South Africa) to Fremantle (Australia), with a focus on trace metal biogeochemistry and chemical oceanography but also including physical and biological oceanographic components. The research topic of the cruise is to determine in detail the distributions, sources and sinks of trace elements and their isotopes (TEIs) in the water column along a zonal section in one of the least studied ocean regions on earth. We aim to investigate the factors controlling the distribution of Nd isotopes and REEs. The supply pathways of these elements and isotopes to the SIO from the ocean boundaries including the atmosphere (Australian dust), continents (mainly South Africa via the Zambezi River), sediments (on continental slopes) will be investigated and their distribution will be compared to hydrographic properties in order to better constrain their suitability as water mass tracers in the present and past ocean. For selected samples and water column profiles we will also determine the distribution of dissolved Si isotopes to trace silicate utilisation in the surface waters (to be compared to N isotope data) and deep water mass mixing. The cruise will officially be part of the internationally coordinated program GEOTRACES.

Job Description / Duties

The candidate will be part of an international GEOTRACES team that will investigate trace metal biogeochemistry in the South Indian Ocean and links to ocean productivity. The candidate will be working closely with physical and biological oceanographers on the cruise programme. The candidate will undertake sampling of trace elements at sea in the South Indian Ocean during cruise SO276. The candidate will analyse samples in the GEOMAR home laboratory, and establish the distribution of trace elements in the South Indian Ocean in relation to sources and water masses, and assess their supply rates to the euphotic zone. The candidate will perform the fieldwork with subsequent sample and data analysis, data interpretation, and scientific manuscript publication. The candidate will need to communicate routinely with other members of the International GEOTRACES programme and will contribute to the project management of the GEOTRACES SIO project.

Postdoctoral position in iron sources to the ocean - AWI, Bremerhaven, Germany

Background and Tasks

The Marine Biogeosciences Section invites applications for a position partially funded by DFG (German Research Foundation) and partially by the AWI strategy fund project DustIron as Postdoctoral researcher to study the contribution of different iron sources to the ocean under present-day and glacial climate conditions, using a global biogeochemical model of iron. This project is in collaboration with the institute of Geology and Mineralogy at the University of Cologne, and the sections Marine Geochemistry, Climate Dynamics and Marine Geology at AWI.

Iron is an essential micronutrient for ocean biota and the enhanced dust deposition has been proposed to be a key factor to lower atmospheric CO2 during the last glacial maximum. There is, however, still no consensus on the mechanisms behind the iron distribution and especially on the relative role of different external iron sources to the ocean (e.g. aeolian dust, marine sediments, hydrothermal and riverine inputs).
A new tool to constrain the role of the different oceanic iron sources is the stable isotopic composition of dissolved iron. You will on the one hand use a global biogeochemical model of iron with an explicit representation of isotopic effects to disentangle the role of different processes affecting the isotopic composition of dissolved iron in the ocean; and on the other hand study the effect of modern and past changes in natural dust deposition over Southern Ocean in a project that aims at improving process understanding in a closely coupled sediment data – model approach.

Requirements

  • You should have a finished doctoral thesis (by the deadline of application) in marine chemistry or biology, environmental sciences, oceanography or a related discipline
  • Knowledge and experience in programming with Fortran and in using Unix/Linux computers is required
  • Experience with climate models or marine biogeochemical models is advantageous
  • You should be willing to work in a multidisciplinary team
  • Very good knowledge of English is expected

Further Information

For further information please contact Dr. Ying Ye (+49 471-4831-2093, Ying.Ye@awi.de) and Dr. Christoph Völker (+49 471-4831-1848, Christoph.Voelker@awi.de).

The position is limited to 2 years. The salary will be paid in accordance with the German Tarifvertrag des öffentlichen Dienstes (TVöD Bund), up to salary level 13. The place of employment will be Bremerhaven.

Please forward your application by January 31st, 2020 exclusively online: https://recruitingapp-5442.de.umantis.com/Vacancies/503/Description/2

Announcement of the GEOTRACES Intermediate Data Product 2021

 

Following from the release of two intermediate data products in 2014 and 2017, the GEOTRACES Data Management Committee is pleased to announce the planned release of the third intermediate data product in July 2021 (IDP2021).

For GEOTRACES principal investigators (PIs) with data to include in IDP2021, we remind you that you need to (1) submit your data to the GEOTRACES Data Assembly Centre (GDAC) or to your National data centre for US, Dutch, French and Chinese PIs, and (2) get your data intercalibrated by the Standards and Intercalibration (S&I) Committee.

The DOoR Portal: To help you with these tasks, we have designed a new interface, the GEOTRACES Data for Oceanic Research portal (DOoR) where you register your data sets for intercalibration and potential inclusion in IDP2021. The DOoR portal does not accept or store your data. Once you have registered datasets, you can download data templates from DOoR for their submission to the appropriate data centre. DOoR is also where you must generate and submit intercalibration reports for processing by the S&I committee. PIs can use DOoR at any time to follow the intercalibration approval process, to link publications, associate scientists (students, postdocs, etc.) and to give permission for the release in IDP2021 for each dataset registered. The DOoR portal has been designed to streamline the preparation of IDP2021, both for the PIs and those who work behind the scenes to assemble the data product. It must be the first port of call for PIs who wish to register their data sets for potential inclusion in IDP2021. You can access the DOoR using your ORCID at this link:

https://geotraces-portal.sedoo.fr/pi

We have provided detailed documentation and links on the DOoR landing page, including a how to document and video guide. We also plan to hold drop-in events at various conferences and workshops in 2020 to demonstrate the use of the DOoR portal and to register datasets with PIs if desired. The first of these will occur at the SCOR booth during the Ocean Sciences Meeting in February 2020. Additional demonstration events in different countries will be announced in due course. PIs can also contact their GEOTRACES Scientific Steering Committee representatives here for more information.

Fair Use of Data: An important change with IDP2021 is our move away from the formal registration step (the “Download Agreement”) towards adherence to a fair use agreement available here, to cover appropriate recognition of data generators in the subsequent usage of IDP2021. All data in IDP2017 will be rolled over to IDP2021 under this fair use agreement. If you do not wish your data to be rolled over from IDP2017 to IDP2021, you must inform the GEOTRACES International Project Office by email as soon as possible (ipo@geotraces.org). If you have already submitted new datasets to your data centre that were not included in IDP2017 please contact GDAC (geotraces.dac@bodc.ac.uk) to discuss processing these data through the DOoR system.

Deadlines for inclusion in IDP2021: The first deadline for the submission of datasets to GDAC (or national data centres for US, Dutch and French PIs) using DOoR templates and intercalibration reports via DOoR to guarantee inclusion in IDP2021 is the 1st of April 2020. After this date we cannot guarantee your data will be included. The final deadline for submission of datasets to GDAC (or national data centres for US, Dutch, French and Chinese PIs) using DOoR templates and intercalibration reports via DOoR, is the 15th of December 2020.

PIs are encouraged to begin the data registration and intercalibration process within DOoR as soon as possible.

Best regards,

Bill Landing and Alessandro Tagliabue,
co-chairs of the GEOTRACES Data Management Committee
