Data Releases
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.

Hydroacoustic data from uncrewed surface vehicle (USV) overtakes in Lakes Huron and Michigan, 2021 Hydroacoustic data from uncrewed surface vehicle (USV) overtakes in Lakes Huron and Michigan, 2021
These data were derived from hydroacoustic data collected by uncrewed surface vehicles (USVs) and powered research vessels. The powered vessels overtook the USVs in Lakes Huron and Michigan to study fish avoidance of survey vessels during traditional acoustic surveys. The water column was divided into three depth groups (epilimnion, metalimnion, hypolimnion) for analysis. Each drone...
Connectivity and Bottlenecks of Habitat Patches along the United States terrestrial coastline of the Great Lakes Connectivity and Bottlenecks of Habitat Patches along the United States terrestrial coastline of the Great Lakes
This dataset maps the connectivity and bottlenecks among habitat patches within a six-kilometer ribbon along the United States terrestrial coastline of the Great Lakes. Each pixel represents the relative value that cell contributes to connectivity between and among habitat patches. When aggregated the pixel values produce a map of all possible pathways between habitat patches providing...
Connectivity and Bottlenecks of Protected Areas along the United States terrestrial coastline of the Great Lakes Connectivity and Bottlenecks of Protected Areas along the United States terrestrial coastline of the Great Lakes
This dataset maps the connectivity and bottlenecks among protected areas within a six km ribbon along the terrestrial coastline of the U.S. Great Lakes. Each pixel represents the relative contribution that cell provides to connectivity between and among the protected areas. When aggregated the pixel values produce a map of all possible pathways between protected areas, providing the end...
