Biogeochemistry and Nutrients in Open-Ocean Waters: Sustainable Ocean Observations from Profiling Floats and Time Series II Posters


Session ID#: 37535

Session Description:
Global biogeochemical cycles of carbon, oxygen, nitrogen and phosphorus, and relatedecosystem processes in the open ocean are being significantly altered by both the directand indirect impacts of human activities. To accurately observe these changes in bothupper and deep ocean waters requires sustained programs of ocean observations and
time-series efforts. These efforts include both ship based observations from repeathydrography or time-series stations, and long-term observations from profiling floats. Inparticular, the number of profiles for biogeochemical parameters returned by profiling floatsin 2016 exceeded the annual mean number of deep (>900 m) profiles entered in World
Ocean Atlas for oxygen, nitrate, or pH over the past decade by a factor of 5. For accurateglobal observations of global changes it is critically important to be able to reliably compareresults from different laboratories and from different platforms with well-quantifiedconfidence. This includes the use of Certified Reference Materials. We welcomecontributions addressing these open ocean biogeochemical observations. We are, inparticular, interested in studies that address the intercomparability of ship and autonomousplatform observations including those using global data sets such as SOCAT, GLODAP,and Biogeochemical-Argo. This includes synthesis and modelling studies of thesebiogeochemical processes.
