Assessment of nutrients and water-quality constituents at the Sacramento-San Joaquin River Confluence during a phytoplankton bloom in July 2017 Assessment of nutrients and water-quality constituents at the Sacramento-San Joaquin River Confluence during a phytoplankton bloom in July 2017
This report documents the spatial and temporal variability of nutrients and related water quality parameters at high spatial resolution in the North Delta in the Sacramento-San Joaquin River Delta of California, USA. The data set includes nitrate, ammonium, phosphate, dissolved organic carbon, temperature, conductivity, dissolved oxygen, turbidity, and chlorophyll. Data-collection were...
Data from historic and contemporary fish community surveys in streams of the Adirondack Region Data from historic and contemporary fish community surveys in streams of the Adirondack Region
The dataset is composed of two data tables containing information from electrofishing surveys conducted in streams of the Adirondack region. The first data table contains information on the sampled reaches and the second data table contains fish collection information. Historical data (1979-1999) were collected by the New York State Department of Environmental Conservation and...
Updated vegetation map of Big Oaks National Wildlife Refuge using 2019 acquired imagery Updated vegetation map of Big Oaks National Wildlife Refuge using 2019 acquired imagery
Big Oaks National Wildlife Refuge (NWR) is a 50,000 acre refuge overlaid on portions of the former Jefferson Proving Ground (JPG) in Jefferson, Jennings, and Ripley counties, Indiana. Beginning in 1996, the U.S. Fish and Wildlife Service (USFWS) began managing the area. Big Oaks NWR was established in June 2000 as an “overlay” Refuge through a 25-year real estate permit from the U.S...
Humpback chub (Gila cypha) capture history data (2009-2020), Grand Canyon, Arizona Humpback chub (Gila cypha) capture history data (2009-2020), Grand Canyon, Arizona
These tabular data were compiled to estimate abundance from paired physical capture and antenna detection data in closed, open, and robust design mark-recapture models. These data represent humpback chub capture histories in the Little Colorado River (LCR) and in the juvenile chub monitoring (JCM) reach of the Colorado River in the Grand Canyon, Arizona. The dataset includes multistate...
