CT14A:
Gases As Tracers of Ocean Biogeochemical and Physical Processes Posters
Session ID#: 84609
Session Description:
This session seeks to bring together the gas tracer community to exchange knowledge regarding new observations, applications, and modeling of gases as tracers for understanding oceanic biogeochemical and physical processes. We welcome contributions on topics including distributions of natural and anthropogenic gases and their isotopes in the ocean, air-sea gas exchange, deliberate tracer release experiments, biological productivity, and atmospheric measurements as they relate to ocean processes. Presentations on observations, method development, modeling, and data synthesis and interpretation are all encouraged.
