Abstract:
Ecosystem metabolism is thought to have powerful feedbacks with the climate system as well as direct impacts on individual taxa that rely on ecosystems for food, water, and shelter. Despite the importance of an ecosystem level understanding, climate change impacts on whole ecosystems remains highly uncertain. In particular, coastal fog-dominated regions are a blind spot for whole ecosystem measurements of the land-air-sea exchange of carbon, water, and energy. To address this critical knowledge gap, our inter-displicary team from the University of California's new Institute for the Study of Ecological Effects of Climate Impacts (ISEECI) has launched a next-generation monitoring program along a gradient of UC Natural Reserve System (NRS) sites. We leverage recent breakthroughs in atmospheric spectroscopy and mechanistic ecosystem models of carbonyl sulfide that provide an unprecedented opportunity to explore the sustainability of coastal systems. Here we present our next-generation monitoring and regional analysis across a North/South transect of UC-NRS sites that has the potential to provide a new window into fog-dominated ecosystems, both currently and under climate change scenarios.
