GEOTRACES Scientific Steering Committee Meeting and Workshop held in Taipei


The 2018 GEOTRACES Scientific Steering Committee (SSC) meeting was held from 23rd to 25th July 2018 at Academia Sinica in Taipei hosted by Prof. Tung-Yuan Ho. The SSC meets once each year to review the progress in the programme implementation and define the future programme agenda. A major topic for discussion this year was how to streamline the process of building the next GEOTRACES Intermediate Data Product planned for 2021. For this, the SSC decided to commit GEOTRACES resources in building an on-line portal which should allow more automatic management of data along with a quick and easy access to the information for all people involved in the construction of the product. This portal should be launched in the coming year. 

The SSC meeting was followed by a 1-day GEOTRACES Training Workshop which was attended by about 60 participants including graduate and undergraduate students as well as young scientists. During the workshop, GEOTRACES senior scientists trained participants on trace metal sampling and analysis together with Ocean Data View (ODV) methods for exploration and analysis of GEOTRACES data.

Thank you to Prof. Tung-Yuan Ho, Wan-Chen Hsieh, Daniel Liao, Vivian Cheng, Sing-How Tuo, Oliver Hsieh, Jenny Tu, Irene Rodriguez, Damo Karri and Ian Wu for the wonderful hospitality and support provided in organising the SSC meeting. We also gratefully acknowledge funding from the following Taiwanese agencies: Ministry of Science and Technology, Ocean Affairs Council, and Research Center of Environmental Changes at Academia Sinica.

New GEOTRACES Data Manager

Mohamed Adjou 

We are pleased to inform you that Dr. Mohamed Adjou has joined the GEOTRACES Data Assembly Centre (GDAC) in the role of GEOTRACES Data Manager.

Dr. Mohamed Adjou has a background in Marine and Climate Sciences (Marine Science Engineer and Climate-Environment Interaction MSc) and hold his PhD in Chemical Oceanography from University of Brest under the supervision of Prof. Paul Treguer. After his PhD he worked as a Postdoctoral Researcher at the University of Copenhagen in close collaboration with Prof. Katherine Richardson on marine ecosystems feedback to environmental forcing using data modelling and observations. The multidisciplinary interest of Mohamed in marine data modelling, data management and software development drove him to develop his skills and to work in this field.

When communicating with Mohamed please use the generic GDAC email account: geotraces.dac@bodc.ac.uk

Welcome on board Mohamed!

The U.S. cruise along the GEOTRACES GP15 section in the Pacific Ocean will depart soon

The U.S. GEOTRACES GP15 cruise will be conducted in the Pacific Ocean along 152° W between Alaska and Tahiti (see map below) from 18 September to 24 November 2018. It aims at examining the influence of strong margin fluxes, atmospheric dust deposition, and the distal ends of hydrothermal plumes from the Juan de Fuca Ridge and East Pacific Rise as well as oxygen minimum zones, equatorial upwelling, and some of the lowest-nutrient waters in the world’s oceans in the South Pacific gyre at 20°S. The cruise will be the first meridional section of the U.S. GEOTRACES programme, and indeed, this transect would allow to explore virtually all of the processes and fluxes known to introduce trace elements to the ocean.

GP15 cruise trackThis project would also provide baseline measurements of trace elements in the Clarion-Clipperton fracture zone (~7.5°N-17°N, ~155°W-115°W) where large-scale deep sea mining is planned. Environmental impact assessments are underway in partnership with the mining industry, but the effect of mining activities on trace elements in the water column is one that could be uniquely assessed by the GEOTRACES community.

This cruise will support a large variety of individual science projects to study the chemical and biological interactions of trace elements, with some research being conducted on board the ship, and additional research at participating academic laboratories (please see the GP15 collaborators web page). In total, 45 researchers will participate in this cruise.

GEOTRACES papers are amongst the most highly cited in Limnology and Oceanography: Methods

The journal Limnology and Oceanography: Methods published by the Association for the Sciences of Limnology and Oceanography (ASLO) is celebrating its 15th year of publication. To celebrate this event, they have published a collection of the most highly cited or downloaded papers – two from each year of publication (2002 to 2017): https://aslopubs.onlinelibrary.wiley.com/doi/toc/10.1002/(ISSN)1541-5856.15thAnniversary

Significantly, two of the 30 papers are GEOTRACES-related and appeared in L&O Methods’ special issue, Intercalibration in Chemical Oceanography (https://aslopubs.onlinelibrary.wiley.com/doi/toc/10.1002/(ISSN)1541-5856.GEOTRACES-VI), that was based on the 2008-2009 GEOTRACES Intercalibration Cruises:
