This child data release includes RGB (red-green-blue) videos acquired from an Unmanned Aircraft System (UAS) during a tracer experiment performed on the Missouri River near Columbia, Missouri, on May 5, 2021. One of the primary goals of this tracer experiment was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) from various types of remotely sensed data in a large, highly turbid natural river channel. Previous research on remote sensing of tracer dye concentrations has focused on clear-flowing streams, but the Missouri River is much more turbid. As a result, the effect of the dye on the reflectance of the water could be obscured by the effects of suspended sediment on reflectance....

A reach of the North Santiam River, Oregon, was used as a case study in an ongoing effort to develop and test image velocimetry algorithms for estimating surface flow velocities in river channels from remotely sensed data. Video was acquired from an unoccupied aircraft system, UAS, and used as input to the image velocimetry algorithms. Direct measurements of flow velocity were obtained using an acoustic Doppler current profiler, ADCP, and used to assess the accuracy of the image velocimetry algorithms. The UAS-based video was acquired from a DJI Matrice 210 quadcopter equipped with a Zenmuse X4S optical camera on July 25, 2022. The video is provided in its native form, with a frame rate of 30 Hertz and an *.mov...

Tribal communities are especially vulnerable to the effects of climate change because of their reliance on the natural environment to sustain traditional activities and their limited resources to respond to climate change impacts. At the same time, tribes have valuable traditional knowledge that can aid regional efforts to address climate change. There were two overarching goals of this project: The first was to build partnerships between South Central Climate Science Center (SC CSC) researchers and tribal communities, linking tribes with climate change tools and resources and developing a model that could be replicated in other regions. The second goal was to document tribal viewpoints on climate change impacts...
The establishment of the South Central Climate Science Center (SCCSC) heralded new forms of partnership among Tribal nations and members of the climate science and conservation communities. But communicating key concepts such as risk and vulnerability is a culturally specific practice. So these new relationships call for pluricultural conversations about climate change and variability. To contribute to the goal of mutual understanding, this project developed and implemented a series of five workshops -- four in Oklahoma and one in New Mexico -- that introduced Tribal members and employees across the region to the SC CSC as a resource for their climate adaptation practices. Not counting members of the research team,...

This data release provides an example data set to accompany the manuscript titled "A Robot Operating System (ROS) package for mapping flow fields in rivers via Particle Image Velocimetry (PIV)", submitted to the journal Software X. This ROS *.bag file contains remotely sensed data acquired during an Uncrewed Aircraft System (UAS) flight along a reach of the Sacramento River near Glenn, California, USA, on September 16, 2022. Cooperators on this project include the Intelligent Robotics Group from the National Aeronautics and Space Administration (NASA) Ames Research Center and the National Oceanographic and Atmospheric Administration (NOAA) Southwest Fisheries Science Center. The file bag6xs600.bag contains a single...

This data release contains digital video files from the USGS field activity 2014-607-FA, a survey of the Oregon Outer Continental Shelf (OCS) Floating Wind Farm Site in 2014. Video data were collected over 3 days between September 6 and September 9, 2014 using a towed camera sled system. 11.6 hours of video were collected along 18 transects; the mean length of time per transect was 38 minutes. Video operations were conducted by deploying up drift of a target and drifting over it at speeds of 1 knot or slower. The video data were collected in order to ground truth geologic and habitat interpretations of sonar data collected during the same field activity. The video-survey locations were chosen after the sonar mapping...
