Session Proposal: Evaluating blue carbon across the tropical/subtropical seascape (AGU25)

B038
Evaluating blue carbon across the tropical/subtropical seascape

Session ID#: 249573

Session Description:
Blue carbon (BC) ecosystems include a variety of coastal settings that can store carbon on millennial timescales. In tropical seascapes, this is mainly mangroves and seagrasses, which display high connectivity across sedimentary and geomorphic settings, and play a vital role in supporting the resilience of vulnerable coastal communities to climate change. BC research spans a wide range of spatial and temporal scales, from site-specific processes to landscape and global patterns, to seasonal and interannual variability, plus long-term trends.In this session, we welcome contributions that use diverse sampling methodologies to evaluate BC and/or its response to climate change and human disturbances. These include field methods (e.g., sediment coring, biomass estimates, flux measurements), ecological modelling, and remote sensing. Quantifying the diverse (sub)tropical seascape has application towards the mitigation of climate change impacts, improved understanding between ocean/climate interactions, and tracking environmental change and disturbance through time.
