All of these files are Microsoft Excel format files that contain Surface Elevation Table (SET) data. We installed deep rod surface elevation tables (SETs) to quantify the relative contributions of surface and subsurface processes to present-day elevation change (i.e., root growth, decomposition, compaction, water flux), shallow subsidence (accretion – elevation), and shallow subsidence between shallow (root zone) and deeper (to >10 m) portions of the soil profile. We installed four SETs at each marsh site, following methods described by Cahoon et al. 2002 and Webb et al., 2013. We established two SETs in low marsh and two in high marsh at each site after visual assessment of vegetation composition and distance from tidal source. We [...]

At the state level, California has highlighted coastal ecosystems as important areas susceptible to climate change and have prioritized research to assist in adaptation planning for resource management and ecosystem services. The information emerging from our CERCC network will provide local managers and decision makers with the information they need to address endangered and threatened species management, wetland conservation, anadromous fish and migratory bird management and habitat conservation and recovery plans while making informed decisions on habitat resiliency and land acquisition planning that effectively considers the effects of climate change. Our CERCC network is a research model that can be potentially transferred to other coastal regions throughout the US. The overarching goal of our research was to use site-specific data to develop local and regionally-applicable climate change models that inform management of tidal wetlands along the Pacific Northwest coast. Our overarching questions were: (1) how do tidal marsh site characteristics vary across estuaries, and (2) does tidal marsh susceptibility to SLR vary along a latitudinal gradient and between estuaries? We addressed these questions with three specific objectives: (1) measure topographical and ecological characteristics (e.g., elevation, tidal range, vegetation composition) for tidal marsh and intertidal mudflats, (2) model SLR vulnerability of these habitats, and (3) examine spatial variability of these projected changes along the latitudinal gradient of the California coast.
