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:

Successful "GEOTRACES IDP 2017 data with Ocean Data View" Workshop held in Qingdao, China

A hands-on workshop to teach standard and advanced Ocean Data View (ODV) methods for the exploration and scientific analysis of environmental data was held on May 2 and 3 2018, Qingdao, China. Total 82 participants attended the workshop including graduate and undergraduate students as well as young scientists, from Ocean University of China. During the workshop, the GEOTRACES Intermediate Data Product 2017 (IDP2017) was used as example dataset. For the day 1, participants learned how to use ODV software, create map, property-property plots, sections, surface plots. In addition, participants also learned how to create ODV data file with their own data set. For the day 2, part of participants (14 students) gave presentations based upon the topics they have interest, which cover Global Physical water circulation, GEOTRACES IDP2017 data, Time-series data (Station Aloha), and their own dataset etc. Lastly, participants learned some tips of advanced level of ODV on how to work on their own dataset.

Participants were encouraged to bring their own laptop computer for use during the hands-on sessions of the workshop. All computers were prepared before the workshop by installing the latest version of the ODV software (ODV 5.0) and downloading the data set. Also, participants were encouraged to fill the survey before the workshop, which helped to understand the participant’s needs and to organize the workshop. The survey was included those questions: Have you ever used ODV before? Have you ever made any “scatter”, “section”, “surface” plots with ODV? Have you ever created own data spreadsheet for ODV and import into ODV? What topic are you interested in the most? i.e. Global Physical water circulation, GEOTRACES IDP2017 data, Time-series data (Station Aloha), Carbon, Hydrothermal vents, and Others. The 63 students were answered those questions, and the main results are available in the workshop report.
