Penobscot River Cross Section Data pre- and post-Dam Removal Penobscot River Cross Section Data pre- and post-Dam Removal
The Great Works (20 feet high) and Veazie (30 feet high) dams on the lower section of the Penobscot River in Maine were removed during the summers of 2012 and 2013, respectively. Channel cross sections upstream and downstream of these dams from just below the Milford Dam to the head‐of‐tide at Eddington Bend just below the former Veazie Dam were surveyed before and after the dams were...
Detections of bison from helicopter and aerial thermal infrared imagery in Grand Canyon National Park, 2019-2021 Detections of bison from helicopter and aerial thermal infrared imagery in Grand Canyon National Park, 2019-2021
These data are detections of bison in Grand Canyon National Park made during helicopter surveys between 2019 and 2021, and an aerial infrared imagery survey done in February 2020.
Field reconnaissance of ground failure triggered by shaking during the 2018 M7.1 Anchorage, Alaska, earthquake Field reconnaissance of ground failure triggered by shaking during the 2018 M7.1 Anchorage, Alaska, earthquake
These data present geolocated photographs, GPS tracks, and field-mapped ground failures collected during the USGS reconnaissance of ground failures following the 2018 M7.1 Anchorage Earthquake.
The Vigil Network: long-term, broad spectrum data collected to observe landscape change in drainage basins The Vigil Network: long-term, broad spectrum data collected to observe landscape change in drainage basins
Long-term monitoring data of geomorphic, hydrological, and biological characteristics of landscapes. This information provides an effective means of relating observed change to possible causes of the change. Identification of changes in basin characteristics, especially in arid areas where the response to altered climate or land use is generally rapid and readily apparent, might provide...
Evaluation of ELISA for the Analysis of Imidacloprid in Plasma, Liver, and Fecal Matter Evaluation of ELISA for the Analysis of Imidacloprid in Plasma, Liver, and Fecal Matter
Neonicotinoids have become the most widely used insecticides in world with rapid growth in applications as seed coatings. Nontarget organisms are exposed to concentrated levels of pesticidal active ingredients through ingestion of treated seeds. To better understand pesticide fate, analytical methods are necessary to rapidly screen and accurately quantitate contaminants in environmental...
Testing transmitter types, harness types, and harness materials for attachment of radio transmitters onto avian chicks Testing transmitter types, harness types, and harness materials for attachment of radio transmitters onto avian chicks
In an effort to facilitate research into the period between fledging and first breeding of juvenile terns we examined the impact of various combinations of harness types (backpack, leg-loop, and 3D printed harnesses), harness materials (Conrad-Jarvis automotive ribbon, Stretch Magic elastic thread, and Teflon ribbon), and transmitter types (CTT LifeTag and Lotek Nanotag) on a surrogate...
Annotated fish imagery data for individual and species recognition with deep learning Annotated fish imagery data for individual and species recognition with deep learning
We provide annotated fish imagery data for use in deep learning models (e.g., convolutional neural networks) for individual and species recognition. For individual recognition models, the dataset consists of annotated .json files of individual brook trout imagery collected at the Eastern Ecological Science Center's Experimental Stream Laboratory. For species recognition models, the...
Repeat microgravity data from Tucson Basin and Avra Valley, Arizona, 2021 Repeat microgravity data from Tucson Basin and Avra Valley, Arizona, 2021
These data represent the network-adjusted results of relative- and absolute-gravity surveys. Relative-gravity surveys were carried out using two ZLS Corporation Burris relative-gravity meters. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations...
Looe Key, Florida, 2016-2017 Seafloor Elevation Stability Models, Maps, and Tables Looe Key, Florida, 2016-2017 Seafloor Elevation Stability Models, Maps, and Tables
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted research to identify areas of seafloor elevation stability and instability based on elevation changes between the years of 2016 and 2017 at Looe Key coral reef near Big Pine Key, Florida, within a 19.74 square-kilometer area. USGS SPCMSC staff used seafloor elevation-change data from...
Upper Florida Keys 1930s-2002 Seafloor Elevation Stability Models, Maps, and Tables Upper Florida Keys 1930s-2002 Seafloor Elevation Stability Models, Maps, and Tables
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted research to identify areas of seafloor elevation stability and instability based on elevation changes between the 1930s and 2002 in the Upper Florida Keys (UFK) from Triumph Reef to Pickles Reef within a 234.2 square-kilometer area. USGS SPCMSC staff used seafloor elevation-change data...
