Data

This data release contains three 10-meter resolution GeoTIFFs representing 10-meter (35-foot), 30-meter (100-foot) and 90-meter (300-foot) riparian buffer zones along shorelines, rivers, streams, and other lotic (flowing) water features. The layers are binary, where the value of each cell represents the presence or absence of the buffer zone. In addition, the data release contains...

Each year from 2021-2024, teams from the US Geological Survey and Virginia Tech studied 30 streams with a targeted gradient of land use and conservation practices across the Chesapeake Bay Watershed. The four years of the study cover the following geographic areas and land use characteristics: -Shenandoah Valley and Ridge pasture -Delmarva row crop -Pennsylvania and Maryland Piedmont...

Chirp sub-botttom data were acquired during USGS field activity 2019-622-FA in August of 2019. The survey was conducted in Lake Crescent, Washington. Geophysical mapping was conducted to investigate earthquake triggered mass transport deposits as part of the Cascaadia Earthquake recurrence project. These data and information are intended for science researchers, students, policy makers...

As part of the Hurricane Sandy Supplemental Project (GS2-2B), scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) and U.S. Army Corps of Engineers (USACE) conducted a nearshore geophysical survey to characterize the stratigraphy of the shoreface and inner shelf near Fire Island, New York (NY) in June and July 2014. The purpose of...

As part of the Coastal Sediment Availability and Flux and DUring Nearshore Event eXperiment (DUNEX) projects, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center and U.S. Army Corps of Engineers, Engineer Research and Development Center (USACE-ERDC) conducted repeat, nearshore geophysical surveys to map the shoreface and characterize...

As part of the 2022 Disaster Supplemental project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey to map the shoreface and inner shelf, as well as characterize stratigraphy near the Chandeleur Islands, Louisiana (LA) in June and August 2023. The purpose of this study was to conduct a...

Groundwater is heavily used for public supply and industrial uses in the Baton Rouge area. Lowered water levels resulting from groundwater withdrawals have induced the movement of saltwater towards wells in East Baton Rouge and West Baton Rouge Parishes. Saltwater intrusion has the potential to affect water supply infrastructure, reduce water availability for certain uses, and increase...

Laboratory studies were conducted to examine the effect of water hardness and age of crayfish on the toxicity of environment-based metals mixture. Additionally, the effects of chronic exposure to a metals mixture to egg development in adult F. quadruncus were assessed. Mortality and growth of F. quadruncus were assessed. These data consist of attributes of water quality from toxicity...

We implemented an online survey questionnaire for adult Massachusetts licensed hunters in December 2022-February 2023 using the Qualtrics survey platform (Qualtrics, Provo, UT). The online survey covers a number of topics related to chronic wasting disease (CWD) such as knowledge, risk perception, management acceptability, hunting behavior, channel use, and trust in different sources. Of...

Chronic Wasting Disease (CWD) is a fatal, contagious, neuro-degenerative disease affecting multiple members of the Family Cervidae. First detected in 1967, the disease has, as of March 2021, been documented in free-ranging and/or captive cervid populations in 26 states, three Canadian provinces, the Republic of South Korea, Norway, Sweden, and Finland. The data provided here contains...

The youngest and largest island in the State of Hawaii—the Island of Hawai‘i—is formed by five volcanoes, three of which have erupted within recent geologic history: Mauna Loa, Kīlauea, and Hualālai. This data release provides a chronology for activity and impacts at Mauna Loa, Kīlauea, and Hualālai over approximately the past two and a half centuries. This data release includes a word...

These data contain the survivorship, hatching dates, and two metrics of sublethal effects of ultraviolet radiation (UV-B; 320 nm) exposure on Cisco (Coregonus artedi) embryos. These data were derived from UV-lamp phototron experiments conducted in the laboratory using fertilized Cisco eggs from wild caught fish from Lake Koronis, MN from 2021 - 2022. Cisco are an important species of...
