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.

Australian process study in the Sourthern Ocean successfully completed

A team of biogeochemists are returning to Australia after a three week voyage to the subantarctic Southern Ocean in the vicinity of the SOTS (Southern Ocean Time Series) site (see figure below).  The science party from Australia (IMAS, Australian National University, Edith Cowan University), the USA (Scripps Institution of Oceanography, Bigelow Laboratory of Oceean SciencesThe University of Tennessee) and Switzerland (University of Bern) sampled for aerosols, dissolved and particulate trace metal's and isotopes and conducted iron rate processes measurements.  A major focus on the voyage was to detail the internal cycling of trace elements in the subsurface ocean via a suite of transdisciplinary perturbation experiments (omics, SXRF, isotopes, ligands, uptake) linked to other components of the voyage that targeted the biological carbon pump.  The voyage builds on prior process studies in this region in 2016, and will link with another planned for early 2019 near SOTS.

US GEOTRACES GP15 cruise Planning Meeting held in Norfolk


The next US GEOTRACES transect will be GP15 in 2018 and led by Old Dominion University’s Greg Cutter, former co-chair of the S&I Committee. His co-leaders on the expedition are Phoebe Lam, current SSC Co-Chair, and Karen Casciotti, current S&I Committee member. It will start on 18 September 2018 in Seattle, Washington, transit to the Alaskan shelf near Kodiak Island and then head south along 152° W to 20° S, with a fuel and food stop in Hilo, Hawaii. There will be a crossover station at 47° N with Japan’s 2017 GP02 cruise for intercalibration. The cruise will end in Papeete, Tahiti on 24 November 2018. There will be 34 scientists on board the US Research Vessel Revelle, examining over 55 TEIs. To coordinate and plan such an endeavor, we held a two day conference 8 and 9 March at ODU, with 56 attendees from as far west as Hawaii and as far north as Alaska – long distances from Virginia, but not as long as the cruise itself – 67 days and 11,000 km! Unique for many US cruises, we will have a professional journalist on board, reporting on the cruise with educational blogs and perhaps videos (depending on bandwidth), and popular magazine articles afterwards. There will also be a public open house in Hilo, Hawaii for local school children and anyone who would like to tour the ship and learn about GEOTRACES.

Congratulations to Catherine Jeandel!


Congratulations to Catherine Jeandel, GEOTRACES IPO senior scientist, who has been elected Geochemical Fellow by the Geochemical Society and European Association of Geochemistry!

Her nomination reads:

Catherine Jeandel, LEGOS, Toulouse (France), for her novel “boundary exchange” hypothesis, in which she identified a previously unknown process that may, in fact, serve as the principal source of many dissolved chemical species in the ocean. Once controversial, studies over the past decade have supported her transformative idea, moving the hypothesis along a steady trajectory from highly controversial to its now established position in marine geochemistry.
