Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Hatchery Trout Predation Data, Arizona

These data were compiled to evaluate the potential adverse impacts that stocked trout may have on native fish populaitons through predation. Hatchery-reared rainbow and brown trout are typically fed exclusively on commercially prepared pelleted feeds and have no experience catching or consuming life fish at the time of stocking and yet stocked fish are percieved to present a high predation...

Controlled source audio-frequency magnetotellurics (CSAMT) data from the Big Chino Wash and Paulden areas, Yavapai County, Arizona

Controlled source audio-frequency magnetotellurics (CSAMT) data were collected in the Big Chino Valley and Paulden areas, Yavapai County, Arizona, to better understand the hydrogeology of the area. CSAMT data provide vertical cross-section (profile) data about the resistivity of the subsurface, which may be related to lithologic boundaries and (or) grain-size distribution in the subsurface....

White mica wavelength position data derived from calibrated Corescan© hyperspectral data

White mica wavelength position data were a derivative dataset produced from Corescan© reflectance data. Corescan Hyperspectral Core Imager Mark III (HCI-III) system data were acquired for hand samples, and subsequent billets made from the hand samples, collected during the U.S. Geological Survey (USGS) 2014, 2015, and 2016 field seasons in the Nabesna area of the eastern Alaska Range...

Sperm motility of quagga mussels exposed to cyanobacteria in a laboratory bioassay, 2016.

These data contain information about sub-lethal effects of cyanobacteria exposure on quagga mussel. Sub-lethal effects of cyanobacteria exposure on quagga mussel (Dreissena rostriformis bugensis) sperm were evaluated. After inducing mussels to spawn using serotonin, sperm were collected and exposed to 11 cultures of cyanobacteria including Anabaena flos-aquae, Aphanizomenon flos-aquae,...

Site table and bias corrections for Coastal Data Information Program (CDIP) hind casts at the California Channel Islands

We present correction coefficients for hourly wave height and period hind casts for 32 sites throughout the Channel Islands National Park and San Nicolas Island. Each site is described in terms of its location, orientation, and transect depth. To use this table, first generate a site-specific wave height and period hind cast using the California Coastal Data Information Program (CDIP)...
