                                            Check timeline for IDP2025

Submission of your datasets requires at least:

  1. Registration of the dataset(s) via the Data for Oceanic Research (DOoR) portal (https://geotraces-portal.sedoo.fr/pi).
  2. Submission of your data using the data and metadata templates downloaded from DOoR to the GEOTRACES Data Assembly Center (GDAC: https://www.bodc.ac.uk/geotraces/ / [email protected]) or your national data centre for Chinese, Dutch, French and USA* scientists*.
    • We very strongly recommend that you use the data template that is offered in the DOoR portal to report your data to GDAC or the appropriate data center.
    • *USA scientists: To increase the efficiency of processing your data for IDP2025, we also strongly recommend that you send your data directly to GDAC in addition to BCO-DMO.
  3. Submission of a complete intercalibration report to the Standards and Intercalibration (S&I) Committee via the DOoR portal (a customized S&I report template can be downloaded from DOoR).
    • An example of a complete report is available at: https://www.geotraces.org/wp-content/uploads/2023/02/Report_Example_Shiller.pdf (please note that if the report is not fully completed will not fulfill the requirement).
    • We very strongly recommend that you submit your S&I reports as soon as possible so that they can be reviewed in time by the S&I!
    • Next meeting of the S&I Committee will be held on 21st March 2024.
  1. Give permission for your data to be included in IDP via the DOoR Portal (https://geotraces-portal.sedoo.fr/pi). If permission is not given your data will not be included in the IDP.

  • Announcement of a Town Hall Meeting on Margin Processes at OSM 2024                       

         There is currently considerable interest in margin processes within the oceanographic community, particularly in the closely related areas of carbon, nitrogen and iron cycling.   To bring multiple investigators together, a group of us proposed a Town Hall Meeting for the OSM 2024 Meeting in New Orleans which was accepted by the Steering Committee.  It will be held on Monday (2/19) from 12:45 to 1:45. Specific location: 220-222, Second Floor (NOLACC). A description of the meeting is available here: https://agu.confex.com/agu/OSM24/meetingapp.cgi/Session/195029
         Much of the rationale arose from conversations within the GEOTRACES community as well as the product of the Benthic Ecosystem and Carbon Synthesis (BECS) Working Group, which has been working under the auspices of OCB for over a year.  This group, led by Jessica Luo (GFDL), Cristina Schultz (Northeastern) and Matt Long (WHOI) has addressed emerging priorities in margin research, and a summary of their activities is in the following link: https://www.us-ocb.org/becs/
          The goal of the town meeting is to start a wider conversation about margin processes amongst geochemists, biologists, physical oceanographers and modelers to talk about common problems.  We are particularly excited about convening a Town Hall at this meeting to engage international researchers. Many groups, especially in Europe and Japan, have well established margin processes and we are keen to learn from them.  It would greatly assist us in planning and addressing issues people care about if you could RSVP (to [email protected]) and fill out the following questionnaire: https://forms.gle/pxezRm9ktXL6ZcUx9
 
We plan to present an overview but the setup is informal, in order to encourage discussion.  If you have some ideas or slides you would like to contribute please send them to us for inclusion – it would be much appreciated.

We have funds for lunch for the first 30 participants!

  • U.S. GEOTRACES cruise GP17-ANT (NBP24-01) completed

         The R/V Nathaniel B. Palmer, arrived in Lyttelton, New Zealand on January 28, 2024, completing the science operations of the U.S. GEOTRACES cruise GP17-ANT. The almost two months cruise was largely successful in achieving its science goals, with 21 stations over the Amundsen Sea continental shelf, 3 stations over the continental slope and 3 off-shelf stations, including one deep-ocean station as a crossover with the preceding GP17-OCE cruise. All stations included collections of samples with a near-surface towfish, a conventional CTD-rosette, a trace-metal clean CTD-rosette, and McLane in-situ pumps. Additional sampling activities included the collection of aerosols, precipitation, sea ice an snow as well as sediment cores for pore-fluid extraction and high-volume pumped seawater samples for radium isotopes and beryllium-7. The heavy sea ice cover prevented access to a number of planned stations including the Thwaites Ice Shelf, Pine Island Bay and the eastern portion of the outer Amundsen Sea shelf. Nonetheless, samples were collected from stations adjacent to the Dotson and Getz Ice Shelves, as well as on- and off-shelf stations impacted by melting sea ice, polynya stations where phytoplankton biomass was extraordinarily high, and a station adjacent to fast ice with near-zero chlorophyll fluorescence. With support from the U.S. National Science Foundation, samples were collected from 23 separate science projects.


  • U.S. GEOTRACES expedition GP17-ANT is sailing in the Southern Ocean

         The U.S. GEOTRACES expedition GP17-ANT (NBP2401) departed Punta Arenas (Chile) on November 29 aboard the R/V Nathaniel B. Palmer, with a team of 35 scientists, led by Peter Sedwick (Old Dominion University), Phoebe Lam (University of California, Santa Cruz) and Robert Sherrell (Rutgers University). This cruise will complete the South Pacific GP17 section, which was initiated with GP17-OCE during December 2022 - January 2023 aboard the R/V Roger Revelle. Because of the potentially important trace elements and isotopes (TEIs) inputs and transformations occurring in Antarctic waters and shelves, GP17-ANT will take place in coastal and shelf waters of Antarctica’s Amundsen Sea. The cruise will arrive in Lyttelton (New Zealand) on January 30, 2024. The cruise is supported by the U.S. National Science Foundation.


           Version 2 is now available!

  • Future Directions for Southern Ocean and Antarctic Coastal Research Report

         With the U.S. GEOTRACES GP17-ANT expedition sailing on November 23, 2023, the announcement of the release of the National Academy report on Future Directions for Southern Ocean and Antarctic Coastal Research is particularly timely. The authoring committee of the report is holding an AGU Town Hall on Thursday, 14 December 2023: 18:30 - 19:30 PST at the Moscone Center, Room: 2007 – West. The committee will be providing a short summary of the report at the Town Hall before opening the session for discussion. A free copy of the report can be found here and a recorded presentation by the authoring committee can be viewed here. We hope to see you there!

        Celebrating Bob's career and his contributions to the field of marine biogeochemistry and ocean sciences.
