This code was created to run a bioenergetics-based model of movement for Galapagos tortoises. It calculates energetic surplus or deficit at a daily time scale based on inputted temperature (6 times a day) and NDVI value (a single value per days), as well as the mass of an individual. It then uses dynamic programming to determine the optimal timing of movement between two foraging habitats, given time-series of NDVI in each habitat, and temperatures in both habitats and in a transition zone between habitats. The model relies on a variety of empirically derived relationships, including allometric relationships, derived for different groups of organisms (i.e., some relationships are based on analyses across multiples...

Seafloor character was derived from interpretations of air photo derived kelp distribution data available for the Santa Cruz Island (Kushner and others 2013). The number of substrate classes was reduced because rugosity could not be derived for all areas. References Cited: Kushner DJ, Rassweiler A, McLaughlin JP, Lafferty KD (2013) A multi-decade time series of kelp forest community structure at the California channel islands: Ecology 94:2655.

This data release contains 43 chirp sub-bottom profiles that were collected in November of 2014 from the Catalina and Santa Cruz Basins offshore southern California by the U.S. Geological Survey Pacific and Coastal Marine Science Center. Data were collected aboard the University of California’s R/V Robert Gordon Sproul on USGS cruise 2014-645-FA. Chirp profiles were collected to assess earthquake and submarine landslide hazards offshore southern California.

The Rare Plant Occurrences geodatabase is an element occurrence data system with about 10,000 records of rare plant observations on the 6 northernmost California Channel Islands. It is a live database created with the purpose of bringing together in one space all discoverable historic and current information on the localities of about 180 rare and sensitive plants of the northern Channel Islands, California. The list of taxa was developed from agency databases, supplemented with a 1-day workshop with area botanists in 1993; the list has been updated as new information emerges. Data records range from the late 1880s to 2019, including information from herbarium labels, published and unpublished literature, agency...

This data release contains 35 multichannel sparker and 24 multichannel minisparker seismic reflection (MCS) profiles that were collected in November of 2014 from the Catalina and Santa Cruz Basins offshore southern California by the U.S. Geological Survey Pacific and Coastal Marine Science Center. Data were collected aboard the University of California’s R/V Robert Gordon Sproul on USGS cruise 2014-645-FA.

Ambient-shade temperature was measured every 4 h with iButton thermochrons (Maxim Integrated Products, Inc., Sunnyville, CA, USA) placed at 1m above-ground level for a previous paper (Blake et al., 2012 – DOI 10.1111/1365-2656.12020). The Normalized Difference Vegetation Index (NDVI) of the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument (Huete et al. 2002 - http://dx.doi.org/10.1016/S0034-4257(02)00096-2) was used as an index of vegetation quantity. Monthly average NDVI values within the range of each tortoise population were derived based on grid sampling within the convex hull created by upland and lowland relocations of migratory individuals during their sedentary (non-migratory) phases of movement....

To support the modeling of storm-induced flooding, the USGS Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for the Southern California Coast and Channel Islands. The Channel Islands are a chain of eight islands where years of isolation has created unique fauna, flora, and archeological resources. The archipelago extends for 160 miles (257 km) between San Miguel Island in the north and San Clemente Island in the south. Five of the islands are part of Channel Islands National Park (Anacapa, Santa Cruz, Santa Rosa, San Miguel, and Santa Barbara), and the waters surrounding these islands make up the Channel Islands National...
