The Humboldt Bay-Eel River region may experience the highest rate of relative sea level rise increase along the West Coast. 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.

CASANC is a polygon coverage showing the offshore boundaries of the national marine sanctuaries (NMS) off central California: Monterey Bay NMS, Cordell Bank NMS, and Gulf of the Farallones NMS and the adjacent coastline. This is one of a collection of digital files of a geographic information system of spatially referenced data related to the USGS Coastal and Marine Geology Program "Monterey Bay National Marine Sanctuary Project" . The data were collected and analyzed between 1994 and 2000.

Three components of the scientific research included a literature review, a geospatial database, and ethnographic research. The literature review surveyed the professional, grey, and peer-reviewed literature on spatial conflicts in the marine environment. Summaries of the literature tracked how stakeholders resolved, mitigated, and addressed space use conflicts. A geospatial database was developed to include available GIS data and new GIS data produced by the study team. The ethnographic data collection occured by engaging individuals and small groups in one on one guided discussions. In addition, the study team convened larger group meetings to describe the study and to develop contacts for further research.

Projected current and future potential distributions of 366 terrestrial vertebrate species, including 12 amphibians, 237 birds, and 117 mammals, based on correlative bioclimatic models and projected changes in biomes. The zipped download file contains habitat suitability maps in a geotiff format, including current distribution (1961 – 1990), and future projected distributions (2070-2099) based on two global circulation models – CGCM 3.1 and Hadley CM3. Detailed description and individual download files are coming soon.

Synopsis: Classical demographic methods applied to life history data on the northern spotted owl yield an estimate of the annual geometric rate of increase for the population of λ = 0.96 ± 0.03, which is not significantly different from that for a stable population (λ = 1.00). Sensitivity analysis indicates that adult annual survivorship has by far the largest influence on λ, followed by the probability that juveniles survive dispersal, and the adult annual fecundity. Substantial temporal fluctuations in demographic parameters have little effect on the long-run growth rate of the population because of the long adult life expectancy. A model of dispersal and territory occupancy that assumes demographic equilibrium...

There are three main components to the ESI: shoreline habitats, sensitive biological resources, and human-use resources. The shoreline and intertidal areas are ranked based on sensitivity determined by: (1) Shoreline type (substrate, grain size, tidal elevation, origin); (2) Exposure to wave and tidal energy; (3) Biological productivity and sensitivity; and (4) Ease of cleanup. The biology layers focus on threatened/endangered species, areas of high concentration and areas where sensitive life stages may occur. Supporting data tables provide species/location-specific abundance, seasonality, status, life history, and source information Human use resources mapped include managed areas (parks, refuges, critical habitats,...

In November 2016, the U.S. Geological Survey acquired high-resolution P- and S-wave seismic data across the surface trace of the West Napa Fault zone at Saintsbury Winery in Napa, California. We acquired seismic reflection, refraction, and guided-wave data along a 115-m-long profile across the known surface rupture zone of the West Napa Fault zone. To acquire the reflection and refraction data, we co-located shots and geophones, spaced every meter along the profile. We used 116 SercelTM L40A P-wave (40-Hz vertical-component) geophones with a sensitivity of 22.34 volts/meter/second to record 116 P-wave shots. We also used 116 SercelTM L28-LBH S-wave (4.5-Hz horizontal-component) geophones with a sensitivity of...

Heavy metal contamination (n=17 metals) of feather and tissue samples from live and deceased Anna's hummingbirds (Calypte anna) was evaluated. Feathers taken from live birds are low in sample weight, therefore a novel method was used in feather sample preparation. Feather samples were then analyzed utilizing an inductively coupled plasma mass spectrometry (ICP-MS) assay. In addition, ICP-MS was used to measure heavy metal concentrations in feather and tissue samples from salvaged hummingbird carcasses. Iron, zinc, selenium and mercury concentrations were most commonly elevated in body feathers from live birds with mercury being the metal most likely to be found in elevated concentrations. Because of this, we conducted...
The primary objective of the research is to develop a rule-based decision support system to predict the relative vulnerability of nearshore species to climate change. The approach is designed to be applicable to fishes and invertebrates with limited data by predicting risk from readily avialable data, including species’ biogeographic distributions and natural history attributes. By evaluating multiple species and climate stressors, the approach allows an assessment of climate vulnerability across habitat types and the impact of specific climate alterations as well as their cumulative impact. A website with a rule-based application for rockfish and crabs is availalble at http://cbrat.org/.

This broad-scale landscape connectivity dataset identifies areas likely to facilitate ecological flow—particularly movement, dispersal, gene flow, and distributional range shifts for terrestrial plants and animals—over large distances and long time periods. Similar to the local permeability analyses (3km radius, Buttrick et al. 2015), this analysis is not species-specific. Rather, it focuses on structural connectivity of natural lands, with resistance to movement modeled as a function of landscape naturalness. This map does not incorporate projections of future climates, nor does it address connectivity for aquatic species. The results identify broad, intact areas where movement of terrestrial organisms is largely...

The Cascadia Tsunami Deposit Database contains data on thelocation and sedimentological properties of tsunami depositsfound along the Cascadia margin. Data have been compiled from52 studies, documenting 59 sites from northern California toVancouver Island, British Columbia that contain known orpotential tsunami deposits. Bibliographical references areprovided for all sites included in the database. Cascadiatsunami deposits are usually seen as anomalous sand layers incoastal marsh or lake sediments. The studies cited in thedatabase use numerous criteria based on sedimentarycharacteristics to distinguish tsunami deposits from sandlayers deposited by other processes, such as river floodingand storm surges. Several...

This service shows the Environmental Sensitivity Index (ESI) developed for Northern California in 2008. Both linear and polygonal shoreline features are included here. Associated GIS datasets can be downloaded here.ESI maps use shoreline rankings to rate how sensitive an area of shoreline would be to an oil spill. The ranking scale goes from 1 to 10.A rank of 1 represents shorelines with the least susceptibility to damage by oiling. Examples include steep, exposed rocky cliffs and banks. The oil cannot penetrate into the rock and will be washed off quickly by the waves and tides.A rank of 10 represents shorelines most likely to be damaged by oiling. Examples include protected, vegetated wetlands, such as mangrove...

In September 2017, the U.S. Geological Survey acquired high resolution P- and S-wave seismic data across the suspected trace of the West Napa Fault zone in St. Helena, California, approximately 70 m north of the previous seismic survey conducted in April 2017 (Chan et al., 2018). We acquired seismic reflection, refraction, and guided-wave data along a 75-m-long profile across the expected trend of the West Napa Fault zone. To acquire the reflection and refraction data, we co-located shots and geophones, spaced every 1 and 2 m along the profile. We used 77 SercelTM L40A P-wave (40-Hz vertical-component) geophones with a sensitivity of 22.34 volts/meter/second to record 60 P-wave shots, and 77 SercelTM L28-LBH S-wave...
