A44A:
Gases as Tracers of Ocean Physical and Biogeochemical Processes II Posters


Session ID#: 7452

Session Description:
This session seeks to bring together the gas tracer community to exchange knowledge regarding new observations, applications, and/or modeling of gases as tracers for understanding oceanic physical and biogeochemical processes. We welcome abstracts on a variety of topics including deriving biogeochemical rates from gases, distributions of natural and anthropogenic gases and their isotopes in the ocean, atmospheric measurements as they relate to ocean processes, tracer release experiments, and process studies of air-sea transfer mechanisms. Presentations on observations, method development, modeling, and data synthesis and interpretation are all encouraged.
