This data release contains mean high water (MHW) shorelines for sandy beaches along the coast of California for the years 1998/2002, 2015, and 2016. The MHW elevation in each analysis region (Northern, Central, and Southern California) maintained consistency with that of the National Assessment of Shoreline Change. The operational MHW line was extracted from Light Detection and Ranging (LiDAR) digital elevation models (DEMs) using the ArcGIS smoothed contour method. The smoothed contour line was then quality controlled to remove artifacts, as well as remove any contour tool interpretation of human-made infrastructure (such as jetties, piers, and sea walls), using satellite imagery from ArcGIS.
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.

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.

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,...
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/.

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 Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The Assessment Unit boundary is defined geologically as the limits of the geologic...

This dataset contains California shoreline change rates derived from mean high water (MHW) shorelines from 1998 (in Central and Southern California) and 2002 (in Northern California) to 2016. The MHW elevation in each analysis region (Northern, Central, and Southern California) maintained consistency with that of the National Assessment of Shoreline Change. The operational MHW line was extracted from Light Detection and Ranging (LiDAR) digital elevation models (DEMs) using the ArcGIS smoothed contour method. Within the Digital Shoreline Analysis System (DSAS), end-point rates (EPR) of shoreline change were calculated between the 1998/2002 and the 2016 shorelines at a transect spacing of 50 meters to provide a long-term...

The U.S. Geological Survey (USGS) compiled data from a variety of national and state agencies to create a comprehensive dataset of streamflow and stage for the lower Columbia River basin and the coasts of Washington, Oregon, and northern California. Seasonal maximum values were calculated for streamflow and stage for the winter (November–March) and spring (April–July) flow seasons, as well as for the full water year (October-September) when underlying data were available.
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 dataset contains shoreline change measurements for sandy beaches along the coast of California over the 2015/2016 El Nino winter season. Mean high water (MHW) shorelines were extracted from Light Detection and Ranging (LiDAR) digital elevation models from the fall of 2015 and the spring of 2016 using the ArcGIS smoothed contour method. The MHW elevation in each analysis region (Northern, Central, and Southern California) maintained consistency with that of the National Assessment of Shoreline Change. Within the Digital Shoreline Analysis System (DSAS), the net shoreline movement (NSM) between the pre-El Nino (2015) and post-El Nino (2016) shorelines was calculated at a transect spacing of 50 meters as a proxy...

Cell maps for each oil and gas assessment unit were created by the USGS to illustrate the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry, or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were...
