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.

Great Lakes seamless topobathymetric digital elevation models and shaded relief maps Great Lakes seamless topobathymetric digital elevation models and shaded relief maps

Modifications were made to existing great lakes topobathy data sets to interpolate areas of missing near shore elevation data. Areas with missing elevation data were not interpolated where there was low confidence in the underlying depth. This included rivers, canals, harbors, lakes, reservoirs, etc. Areas important for targeting Phragmites australis management often lie within these...

Anesthetic properties of carbon dioxide on native and invasive fishes Anesthetic properties of carbon dioxide on native and invasive fishes

This study evaluated the anesthetic properties of dissolved carbon dioxide on six fish species to determine its efficacy for use in sedating wild caught fish for surgeries. Phase I of this study aimed to inform induction time, recovery time, and short-term survival of fish using five different concentrations of carbon dioxide at one water temperature. Phase II determined the induction...

Acute Toxicity of Carbon Dioxide to Crayfish Acute Toxicity of Carbon Dioxide to Crayfish

This study evaluated the use of dissolved carbon dioxide as a control method for invasive crayfish. Five concentrations of CO2 were administered to twenty-four test tanks at a water temperature of 5°C. Initially, Red Swamp Crayfish (RSC; Procambarus clarkii) were intended to be the test species used in the study. However, problems with obtaining a healthy population of RSC occurred, so...

Projections of Elevation and Mangrove Species Cover under Sea-Level Rise across Pohnpei, Federated States of Micronesia Projections of Elevation and Mangrove Species Cover under Sea-Level Rise across Pohnpei, Federated States of Micronesia

Future sea-level rise poses a risk to mangrove forests. To better understand potential vulnerability, we developed a numerical model of soil elevation for mangrove forests. We used the model to generate projections of elevation and mangrove forest composition change under six sea-level rise scenarios from 2020 through 2150. We employed a data-driven modeling approach, utilizing new and...
