Annual California Sea Otter Census - 1985-2014 Spring Census Summary This dataset represents an archived record of annual California sea otter surveys from 1985-2014. Survey procedures involve counting animals during the "spring survey" -- generally beginning in late April or early May and usually ending in late May early June but may extend into early July, depending on weather conditions. Annual surveys are organized by survey year and within each year, three shapefiles are included: census summary of southern sea otter, extra limit counts of southern sea otter, and range extent of southern sea otter. The surveys, conducted cooperatively by scientists of the U.S. Geological Survey, California Department of Fish and Wildlife, U.S. Fish and Wildlife Service and Monterey Bay Aquarium...

The point cloud is referenced to previously published lidar data and contains RGB information as well as XYZ. Point cloud coordinates are in NAD83 UTM Zone 10 meters. Imagery was collected with a Nikon D800 camera in RAW format and processed using structure-from-motion photogrammetry with Agisoft PhotoScan version 1.2.8 through 1.3.2. Pointclouds were clipped to an AOI using LASTools. The AOI was created from a KMZ in Google Earth and transformed to a shapefile using ArcMap 10.5.

These data were collected during the spring 2019 range-wide census. The USGS range-wide sea otter census has been undertaken each year since 1982, using consistent methodology involving both ground-based and aerial-based counts. The spring census provides the primary basis for gauging population trends by State and Federal management agencies.

To estimate seepage using temperature, the diel amplitude and attenuation of temperature at several depths below the streambed must be monitored, as well as the frequency and duration of streamflow in a channel (Narranjo and Smith, 2016). Special subsurface temperature rods (TRODS) were developed to address these most of these needs (Narranjo and Turcotte, 2015). A TROD consists of discrete temperature iButton sensors within a .75 inch (in) diameter 1 meter (m) long sealed, water-proof PVC pipe to prevent water damage to the sensors. A TROD is installed into stream channel sediments and measures surface water and sediment temperatures...

SGFZ is a right-lateral fault system that is mainly offshore, and prior studies provide highly variable slip estimates, which indicates uncertainty about the seismic hazard it poses. Therefore, the primary goal of the seismic survey was to better understand the structure and geometry of the onshore section of the Frijoles Fault strand of the SGFZ. We deployed 118 geophones (channels) at 5-m spacing along a linear profile centered on the mapped surface trace of the Frijoles Fault and co-located active P- and S-wave sources...

The SACVW, is about 140 square miles and encompasses the San Antonio Creek Valley groundwater basin; From the late 1800s, groundwater has been the primary source of water for agricultural, military, municipal, and domestic uses. Groundwater withdrawal from pumping has exceeded the amount of water replenishing the basin, causing groundwater declines of more than 150 feet in parts of the valley between 1943 and 2017, and reducing base flow in San Antonio Creek at the western end of the SACVW.

Cylinder infiltrometers are generally constructed from metal shaped into cylinders which are driven into the ground and flooded with water. The rate at which water infiltrates into the ground is measured until the rate of infiltration is constant to capture unsaturated infiltration rates and beyond steady state to measure saturated infiltration rates and conductivity (Bouwer, 1986). Infiltrometers are typically employed to measure the rate of infiltration on inundated soils such as surface irrigation, seepage from surface water such as streams or reservoirs, or infiltration basins for groundwater...
