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

Successful GEOTRACES summer school held in Spain

The 2nd GEOTRACES Summer School was hosted by the International Campus of Excellence of the Sea (CEI · Mar, Cadiz, Spain) on board the Spanish school vessel ‘Intermares’.

While society begins to demand greater attention to the oceans, science continues to follow the path that oceanographers have traced since more than a hundred years now. Global climate mobilizations start to put pressure on international politics at the same time that a new generation of scientists, the best trained so far, is trying to enter in the global labour market with very limited resources.

They are the best brains on the planet to study the oceans, they all speak in English regardless of where they came from and, for now, they do not bother of gender differences, however: do they know where the data they will later study and use to define models to preserve the marine environment came from? The truth is that they often do not have the possibility of being trained on this basic part of the science to which they dedicate their lives.

To solve this, the GEOTRACES International Programme which is an extensive worldwide network of marine geochemists that follow accurate protocols to sample, analyse and share their trace metal knowledge and data, has chosen Cádiz to held its training programme through the ‘International Summer School GEOTRACES-Spain’.

The International Campus of Excellence of the Sea (CEI · Mar) has taken over the coordination, with the support of the Consejo Superior de Investigaciones Científicas (CSIC) through ICMAN-CSIC and the University of Cádiz (UCA). Moreover, several collaborating institutions have also participated: the Secretaría General de Pesca and the Spanish Navy have provided the school vessel where all the training has been carried out; and the Port Authority of the Cadiz Bay has facilitated the docking and supplies, among others.

The selection of participants was tough. Only the 39 best candidates under 40 years old from more than a hundred of applicants were selected. To attract them to Cadiz, coming from countries such as the United States, India, Brazil, Germany, among 15 other nationalities, the Summer School offered a series of sampling workshops on board the ‘Intermares’ vessel and a faculty composed of word-leading international experts. A list of scientific excellence: Bob Anderson (LDEO, Columbia University – USA); Catherine Jeandel (LEGOS, France); Reiner Schlitzer, Alfred Wegener Institut (AWI), Germany; Susanne Fietz (Stellenbosch University, South Africa); Eric Achterberg (GEOMAR, Germany); Maite Maldonado (British Columbia, Canada); Mohamed Adjou (Brtish Oceanographic Data Center,UK); Géraldine Sarthou (CNRS – France); Rob Middag (NIOZ, The Netherlands); José Antonio López (Universidad de Cádiz); and Antonio Tovar (ICMAN/CSIC Spain)… a very, very intense schedule remained.

Among the most exciting experiences of the summer school were the field sampling workshops on board of the ‘Intermares’ vessel. Every morning, after the master lecture, the vessel was heading to a point away from the Bay of Cádiz looking for 100 meters deep to submerge a rosette including eight bottles from which seawater samples were extracted. Each pair of students took a bottle and brought it to the laboratory installed on the ‘Intermares’ school vessel. In there they continued learning how to follow the strict GEOTRACES protocols that allows getting uncontaminated seawater samples. Trace metals are available in very low concentrations in the ocean so any accidental addition may ruin the entire process. First, and dressed for the occasion, they entered in the “bubble”; a clean environment of particles and metals for a first extraction. Next, they went to the laminar flow hood, where the air was filtered in order that the samples were not contaminated with other particles when it is manipulated. From there, to the laboratory where marine students usually work whatever the place of the world in which his/her research institution is located.

Despite the intensity of the summer school, the strength of these young scientists made it possible to achieve the second objective of the course: establishing a working network that will last and become strong over time. All of them were representing the “crème de la crème” of the world-leading research groups in marine trace metals, not very abundant but key to the functioning of marine ecosystems.

The ‘International Summer School GEOTRACES Spain’ has been a great experience, a unique opportunity to see these students work and even more, to grow. They will be basing on their acquired knowledge to design and execute policies that truly preserve the oceans and improve the effects of global climate change. Thanks to the teamwork of all the organizations that have made it possible: GEOTRACES, Universidad de Cádiz, Scientific Committee on Ocean Research (SCOR), ICMAN-CSIC, Fundación CSIC, EIDEMAR, Ministry of Agriculture and Fisheries; and Ministry of Defense. Each and every one of them has been necessary so that the next generation of marine scientists specialized in trace metal research receives a training of excellence...

...and a very special THANKS to the organising committee; the local hosts especially Antonio Tovar, Antonio Lopez, Juan Vergara, Mercedes Morales and Eva Mena; and all the lecturers who made this summer school possible!

Asia GEOTRACES Workshop

Asia GEOTRACES Workshop: 

Sources/sinks and internal cycling of mercury and other
TEIs in the Northwest Pacific Ocean

Qingdao, Shandong, China

December 8-10, 2019

About the workshop

GEOTRACES project covers global oceans, including the Northwestern Pacific Ocean (NWPO). However, the knowledge on regional distributions and internal cycling of trace elements and their isotopes (TEIs) in seawaters in the NWPO is still limited.

For example, mercury (Hg) cycling in the oceans has drawn extensive public concerns because of the production of methylmercury (MeHg) in the marine environments. The produced MeHg can then be biomagnified via food chain, bioaccumulated to high concentrations in organisms at high trophic levels and pose great threat to human health. Some efforts have been made on investigating the distribution and cycling of Hg in the Pacific Ocean. East Asia is the largest source region for Hg. Large amounts of Hg were discharged into the ocean via riverine input and atmospheric deposition, highlighting the importance of this region in Hg studies. However, there is lack of studies on the distribution and cycling of Hg in the NWPO. Few mercury data following the GEOTRACES protocols were reported in this region and controlling processes and factors for Hg cycling in the NWPO are largely unknown.

As major GEOTRACES ocean interfaces, exchange between atmosphere and surface water, sediments and the overlying water column significantly influence the net sources and sinks for dissolved TEIs in seawater, as well as the internal cycling of TEIs in the NWPO. However, little is known about net supplies of TEIs from sediments and atmosphere as well as the key processes and key areas for the supplies in the NWPO. The marginal seas in the NWPO, such as Bering Sea, Sea of Okhotsk, East China Sea, and South China Sea, receive significant amount of lithogenic and anthropogenic substances from fluvial input and submarine groundwater discharge. These marginal seas are also important source areas that supply trace elements to the NWPO, which can highly influence TEIs cycling in open ocean. The major transport processes and fluxes for TEIs in each individual marginal sea remain to be explored. The major western boundary current of the NWPO, the Kuroshio, flows exactly through the region between the marginal seas and the NWPO, passing by the eastern ends of Philippine and Taiwan and mixed with the seawater originated from the East and South China Seas, then going northeastern direction to form the Kuroshio extension. The dynamic Kuroshio system not only links the NWPO and its marginal sea but also indicates the necessity for regional collaboration to fully understanding TEIs cycling in the oceanic region.

An Asia GEOTRACES Workshop, organized by Ocean University of China, will be held in Qingdao on December 8-10, 2019. In this workshop, we plan to invite GEOTRACES scientists in Asia as well as other regions to evaluate a full picture of the current status of the studies on the major sources/sinks and internal cycling processes of TEIs in seawater (emphasized on mercury) in the NWPO, and to generate a future regional collaboration and action plan for Asia GEOTRACES.

2019 GEOTRACES Scientific Steering Committee Meeting held in Australia

The 2019 GEOTRACES Scientific Steering Committee (SSC) meeting was held from 9th to 11th September at the Institute for Marine and Antarctic Studies (IMAS) of the University of Tasmania in Hobart, Australia, hosted by Andrew Bowie and Zanna Chase. During the meeting, the SSC members reviewed the progress in the programme implementation and defined the future programme agenda. The major topics for discussion were the review of the new on-line portal to register data to be included in future GEOTRACES Intermediate Data Products (IDP) and the timeline for the release of the forthcoming IDP2021. Both the portal and the timeline will be presented to the GEOTRACES community very soon!

The SSC meeting was preceded by a 2-day workshop on exploring GEOTRACES and other environmental data with Ocean Data View (ODV) given by Reiner Schlitzer (AWI, Bremerhaven) and attended by 40 participants. A workshop on Southern Ocean Biogeochemistry followed the SSC meeting from 12th to 13th of September. The workshop was aimed at briging together national and international scientists as well as local students and researchers in biogeochemical oceanography, modelling and paleoceanography focused on the Southern Ocean’s response to climate change. During the workshop the development of collaborative projects including GEOTRACES process studies was also discussed. The programme of the workshop is available here.

Thank you to the meeting hosts Andrew Bowie and Zanna Chase for their wonderful hospitality, to Phil Boyd for his help in organising the Southern Ocean workshop and, to Scott Meyerink for all his assitance during all these events.  We also gratefully acknowledge funding from the Institute for Marine and Antarctic Studies, the Antarctic Gateway Partnership and the Antarctic Climate and Ecosystem Cooperative Research Centre.
