Coastal ecosystems, such as coral reefs, kelp forests, seagrass communities, estuaries and mangrove forests, have major roles in the dynamics of global carbon cycling relative to their sizes. Unfortunately, these environments are increasingly and disproportionately vulnerable to the compounding effects of global climate change and local anthropogenic stressors. Ocean warming, acidification, hypoxia, nutrient loading and sedimentation are driving ecological change at rates that challenge ecosystem resilience and management efforts. Understanding how these stressors interact and impact ecosystem function requires interdisciplinary approaches and the application of analytical tools that offer insights into ecosystem metabolism, organic and inorganic elemental cycling, carbonate chemistry, contaminant pathways, and more. This session will explore how biogeochemical approaches can be used to detect, quantify, and predict coastal ecosystem responses to both short-term disturbances (e.g., heatwaves, wildfires, floods) and long-term stressors (e.g., climate change, eutrophication, ocean acidification). We invite contributions that span field-based studies, laboratory experiments, remote sensing, modeling, and novel monitoring technologies. We are especially interested in research that addresses cumulative impacts, ecosystem tipping points, and solutions-oriented science that can inform management and policy.
