Ground-based lidar data of the southeast face of El Capitan, Yosemite National Park, California, May 4, 2022 Ground-based lidar data of the southeast face of El Capitan, Yosemite National Park, California, May 4, 2022
We collected two ground-based (terrestrial) lidar scans of the southeast face of El Capitan cliff, located in Yosemite National Park, California. El Capitan is one of several iconic granitic cliffs in Yosemite and rises approximately 1000 meters above the floor of Yosemite Valley. The scans were collected from the same location and from a single vantage point on the edge of El Capitan...
Survival of Greater Sage-Grouse Nests and Broods Following Translocation in California, Wyoming, and North Dakota, 2002 - 2019 Survival of Greater Sage-Grouse Nests and Broods Following Translocation in California, Wyoming, and North Dakota, 2002 - 2019
These tables provide observations of sage-grouse, both translocated and not, during the nesting and brooding phases. With respect to nests we include observations of clutch size, egg hatchability, and adult survival during this period. For the brooding period we include both adult and chick survival as well as initial and final brood size. Lastly, we include peak male counts at leks for...

Assessment of Submerged Aquatic Vegetation in Lake Michigan Using Down-Looking AUV-Collected Imagery Assessment of Submerged Aquatic Vegetation in Lake Michigan Using Down-Looking AUV-Collected Imagery
This dataset comprises in situ images of benthic algae collected by an autonomous underwater vehicle (AUV) in Lake Michigan during August and September 2020. The images were annotated, or labeled, to identify specific features for use in machine learning and algorithm development, specifically to train and validate an algorithm for the automated identification and assessment of submerged...
Timing of coral (Swiftia exserta) spawning in U.S.G.S. Wetland and Aquatic Research Center, Gainesville, FL Timing of coral (Swiftia exserta) spawning in U.S.G.S. Wetland and Aquatic Research Center, Gainesville, FL
The 2010 Deepwater Horizon oil spill injured mesophotic and deep-sea environments over a vast area. In order to restore the mesophotic and deep-sea coral species impacted by the spill, information on fundamental ecosystem processes such as reproduction is needed. During expeditions in 2021 and 2022, fragments of the mesophotic octocoral Swiftia exserta were collected from the northern...

This data release contains information derived from fishing efforts and sampled fish from the nearshore Beaufort Sea, Alaska, 2021-2023, as part of a study investigating red-throated loon productivity and diet. The datasets include six tables comprising 1) catch per unit effort (CPUE) data, 2) field-measured lengths of fish (mm), 3) the energy density (kJ/g) and whole-body energy (kJ) of...
Probability of Streamflow Permanence (PROSPER) Model version 2.1 Output Layers for the Pacific Northwest region, 2004 - 2016 Probability of Streamflow Permanence (PROSPER) Model version 2.1 Output Layers for the Pacific Northwest region, 2004 - 2016
This data release contains the model inputs, outputs, and source code (written in R) for a redeveloped PRObability of Streamflow PERmanence (PROSPER) model (version 2.1) that had previously been developed for the Pacific Northwest Region (PROSPER_PNW_2), and a raster data set which shows where influential predictor values were outside the range of calibration data. The PROSPER-PNW...
