2016 Ocean Sciences – GEOTRACES Town Hall and Tutorial
Town Hall “Opportunities to Strengthen Your Science (and Proposals) using GEOTRACES Data”
Thursday, February 25, 2016: 6:30 PM – 7:30 PM
Location: Ernest N. Morial Convention Center, 228-230
Refreshments will be available.
2016 Ocean Sciences Meeting, New Orleans, USA
Description: GEOTRACES released its first intermediate data product (IDP2014), featuring dissolved trace elements and their isotopes, during the 2014 Ocean Science meeting. The next data product (IDP2017) will more than double the amount of data and number of variables, including particulate elements. This town hall will: 1) Inform the community about strategies to access, download and manipulate data from IDP2014 and provide preliminary information about IDP2017; 2) Seek feedback from users of IDP2014 to improve IDP2017 and make it as user-friendly as possible; and 3) Present the outcome of the first Iron-Model Intercomparison Project (FeMIP), in which comparison to GEOTRACES data allowed an unprecedented assessment of model performance.

Tutorial (T014) “What Controls the Distribution of Dissolved Iron in the Ocean?”
Primary Chair: Alessandro Tagliabue (University of Liverpool)
Tuesday, February 23, 2016: 03:30 PM – 04:00 PM
Location: Ernest N. Morial Convention Center – RO3
2016 Ocean Sciences Meeting, New Orleans, USA
Description: Due to its role as a limiting nutrient in the Southern Ocean, the role for iron in governing how ocean productivity influences wider biogeochemical cycling and atmospheric carbon dioxide levels is well accepted. Around twenty years ago the first compendium of dissolved iron observations was published, enabling initial insights into the controls on its cycling and distribution. Today the number of compiled iron observations stands in the tens of thousands and is growing further thanks to the efforts of the GEOTRACES programme. In this tutorial I will review the new insights gained into the controls on the oceanic iron distribution that illuminates important roles for a range of sources and identifies crucial components of its biological cycling. These emerging ideas place important constraints on our efforts to represent the iron cycle in the global ocean models used for integrating to basin and global scales, as well as climate prediction. In this context I will discuss how the role for iron in controlling past atmospheric carbon dioxide and future ocean productivity has matured. Finally, I will highlight the key challenges that need to be tackled over the coming years, with an emphasis on the opportunities provided by additional observational constraints.
