All of these files are Access Databases that contain RTK elevation survey data and the corresponding vegetation surveys that were conducted concurrently. Over 2,000 intertidal plots were sampled for plant cover, frequency of occurrence, and species richness across the six study sites. Approximately 57 vascular plant species were found in the study, including grasses, rushes, forbs and sedges. Vegetated marsh ranged in elevation from approximately local mean tide level (MTL) to the marsh-upland transition zone (upland plots, defined as areas estimated to flood 1 time per year on average, were not considered for further analysis). We assessed vegetation cover and species richness concurrently with elevation surveys...

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...

Sea star wasting disease (SSWD) is a suite of poorly described non-specific clinical signs including abnormal posture, epidermal ulceration, and limb autotomy (sloughing) causing mortalities of over 20 species of sea stars and subsequent ecological shifts throughout the northeastern Pacific. While SSWD is widely assumed to be infectious with environmental conditions facilitating disease progression, little data exist on cellular changes associated with disease that could inform mechanisms of disease pathogenesis and host susceptibility. Here, we replicated SSWD by exposing captive Pisaster ochraceus to a suite of non-infectious organic substances and show that development of gross lesions is a basal to surface process...

Core names are in the format: SitecodeYear-Core#, i.e. TJE12-01 is Tijuana, 2012, 1st core. cm are the lower depth interval of the cm from which sample was taken, i.e. a sample from 50 cm would be from 49-50 cm depth. Radiocarbon data processed at the UCI Keck CCAMS Laboratory, Earth System Science Department, 2222B Croul Hall, University of California, Irvine, Irvine, CA 92697-3100, +1 949 824 3674. 137 Cs activity data analysis by Core Scientific International, 154 Red Lily Road, Winnipeg, Manitoba, Canada R3X 0G1, (204) 479-9821, (204)694-4130.

All of these files are Microsoft Excel format files that contain water level data. We deployed 1-4 water level loggers and a single conductivity logger at all sites over the study period (Figure 6; Table 2). Primary water level loggers and conductivity loggers were deployed in major tidal channels connecting the marshes to the estuary. Secondary water level loggers were deployed in the upper reaches of second-order tidal channels to capture high tides and determine inundation patterns. Water level readings were collected every six minutes. We used data from the primary water level logger at each site to develop local hydrographs and inundation rates. Loggers were surveyed by RTK GPS at least once during the period...
