BN53A:
Biogeochemistry and Nutrients in Open-Ocean Waters: Sustainable Ocean Observations from Profiling Floats and Time Series III


Session ID#: 37574

Session Description:
Global biogeochemical cycles of carbon, oxygen, nitrogen and phosphorus, and related
ecosystem processes in the open ocean are being significantly altered by both the direct
and indirect impacts of human activities. To accurately observe these changes in both
upper and deep ocean waters requires sustained programs of ocean observations and
time-series efforts. These efforts include both ship based observations from repeat
hydrography or time-series stations, and long-term observations from profiling floats. In
particular, the number of profiles for biogeochemical parameters returned by profiling floats
in 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 accurate
global observations of global changes it is critically important to be able to reliably compare
results from different laboratories and from different platforms with well-quantified
confidence. This includes the use of Certified Reference Materials. We welcome
contributions addressing these open ocean biogeochemical observations. We are, in
particular, interested in studies that address the intercomparability of ship and autonomous
platform observations including those using global data sets such as SOCAT, GLODAP,
and Biogeochemical-Argo. This includes synthesis and modelling studies of these
biogeochemical processes.
