Seeking nominations for new OCB Subcommittee Ocean Carbonate System Intercomparison Forum (OCSIF)

We are currently seeking nominations for members of a newly established OCSIF topical subcommittee of the OCB SSC – the Ocean Carbonate System Intercomparison Forum (OCSIF). This subcommittee has its origins in the OCB OCSIF working group focused on identifying and addressing uncertainties in the seawater carbonate system and increasing measurement inter-comparability, with goals of

What is OCB?

OCB is a dynamic network of scientists working across disciplines such as ocean chemistry, biology, and physics to understand the ocean’s role in the global carbon cycle and how marine ecosystems and biogeochemical cycles are responding to environmental change.
