Model Archive Summary for a Suspended-Sediment Concentration Surrogate Regression Model for Station 404038124131801; Hookton Slough near Loleta, CA Model archive summary (MAS) describing the development of a suspended-sediment concentration (SSC) surrogate regression model for the Hookton Slough near Loleta, CA water quality station (USGS site ID# 404038124131801). A continuous 15-minute SSC record was computed using this regression model for the period of record (03-04-2016 to 09-10-2019). The computed SSC record can be found on NWIS Web at https://waterdata.usgs.gov/ca/nwis/uv?site_no=404038124131801. The SSC record was used to assess ambient SSC conditions, the availability of suspended sediment to support surface deposition and elevation gain in adjacent salt marshes, and to characterize salt marsh resiliency to climate change impacts in Humboldt Bay, CA.

The Project will engage stakeholders to discuss community and science needs for planning and implementing adaptation measures to sea level rise. The Project is a critical step in developing an ecosystem based-management (EBM) approach to guide the protection, management, enhancement, adaptation, restoration, and possible redistribution of Humboldt Bay-Eel River Delta habitats under future climate scenarios. This process will be informed by the best-available science, the needs of Humboldt Bay-Eel River Delta agricultural producers, and other community members.

At selected salt marsh parcels in both the North Pacific and California LCCs, data collection techniques were employed to assess detailed baseline habitat elevations; tidal ranges, microclimate, and extreme weather events; sediment supply sources; vegetation community composition; and vertebrate population indices. The design provides resource managers with information on the value of different datasets and methods including their uncertainty, as well as determines their usefulness in climate change adaptation planning...

Data were taken at every fourth (25%) elevation point (n=740 quadrats; Fig. 4). We measured height (mean and maximum, measured within 0.05 m) and visually estimated percent cover for each species within each quadrat. This allowed us to develop a relationship between plant species, elevation and tidal datum across all sites. We also characterized the most common species, which were defined as those found at>10 % of the plots. Plant species frequency was plotted relative to MHW. This comprehensive...

These saltmarshes, mudflats, and shallow bays are not only critical for wildlife, but they also provide economic and recreational benefits to local communities. Today, sea-level rise, more frequent and stronger storms, saltwater intrusion, and warming water temperatures are among the threats that are altering these important habitats. To support future planning and conservation of California’s near-shore habitats, researchers examined current weather patterns, elevations, tides, and sediments at these sites to see how they affect...

The overarching questions were: (1) how do tidal marsh site characteristics vary across estuaries, and (2) does tidal marsh susceptibility to sea-level rise (SLR) vary along a latitudinal gradient and between estuaries? These questions are addressed in this data collection 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)...

These marshesprovide important habitat for marsh-dependent species, such as Humboldt Bay Owl’s Clover(Castilleja ambigua), Western Snowy Plover (Charadrius alexandrinus nivosus), and Steelhead(Oncorhynchus mykiss).

To plan and manage for future scenarios, managers need access to data, models, and training on the best-available science. To address this need, the USGS Western Ecological Research Center has worked with federal, Tribal, state, and local partners to establish a network of study sites in 17 estuaries along the Pacific Coast, examining the climate change effects on tidal wetlands with high-quality local data, downscaled models, and projected storm effects. Study sites include ten USFWS National Wildlife Refuges and four NOAA National Estuarine Research Reserves.
