Data and Tools

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.

Historical Spawning Sites for Lake Whitefish (Coregonus clupeaformis) and Cisco (Coregonus artedi) in Lake Erie and Connecting Channels, 1850-1960

Coordinate locations for historical spawning locations of Lake Whitefish (Coregonus clupeaformis) and Cisco (Coregonus artedi) were summarized using ArcGIS 10.5. There were 30 sites for Cisco and 78 sites for Lake Whitefish documented across the Lake Erie basin, including the Detroit River, Lake St. Clair, and the St. Clair River. Data came from published and unpublished sources cited in the...

The timing of dabbling duckling hatch, nest departure and depredation in Suisun Marsh, California from 2015-2017

These data include a row for each duck nest equipped with a small video camera. We present the location of the nest, the timing of the start of hatch, the timing of the end of hatch, and the timing of the departure of the hen and ducklings from the nest. Additionally, this table includes any predators that were observed at the nest depredating eggs prior to hatch and any predators that were...
