Vegetation and Temperature Data, Smith River Estuary, Alaska, 2011-2013 Vegetation and Temperature Data, Smith River Estuary, Alaska, 2011-2013
This data release contains measurements of vegetation samples and temperature collected from experimental plots of Carex subspathacea along the Smith River Estuary, Alaska (2011-2013).
Multi-element geochemical analyses of samples from the Mesoproterozoic Nonesuch Formation and Copper Harbor Conglomerate at the Copperwood copper deposit, Western Syncline, Michigan, USA Multi-element geochemical analyses of samples from the Mesoproterozoic Nonesuch Formation and Copper Harbor Conglomerate at the Copperwood copper deposit, Western Syncline, Michigan, USA
This data release provides multi-element data for drill core samples from the Mesoproterozoic Nonesuch Formation and Copper Harbor Conglomerate at the Copperwood copper deposit, Michigan, USA. Copper was determined by assay, and sulfur by inductively coupled plasma-optical emission spectrometry (ICP-OES) after aqua regia digestion for most samples. Multi-element whole rock analyses were...
Gallium Deposits in the United States Gallium Deposits in the United States
This U.S. Geological Survey (USGS) data release provides the descriptions of the only U.S. sites—including mineral regions, mineral occurrences, and mine features—that have reported production and (or) resources of gallium (Ga). The sites in this data release have contained resource and (or) past production of more than 16 metric tons Ga metal, which was the approximate average annual...
Dataset for temporal influences on selenium partitioning, trophic transfer, and exposure in a major U.S. river Dataset for temporal influences on selenium partitioning, trophic transfer, and exposure in a major U.S. river
The trace element selenium is an essential element with a narrow window between concentrations needed to support life and those that cause toxicity to egg laying organisms. Selenium bioaccumulation in aquatic organisms is primarily the result of trophic transfer through food webs and is poorly predicted by dissolved concentrations in freshwater bodies. To better understand the hydrologic...
Aerial imagery and structure-from-motion data products from UAS survey of the intertidal zone at Post Point, Bellingham Bay, WA, June 2019 Aerial imagery and structure-from-motion data products from UAS survey of the intertidal zone at Post Point, Bellingham Bay, WA, June 2019
An unmanned aerial system (UAS) was used to acquire high-resolution imagery of the intertidal zone at Post Point in Bellingham Bay, Washington on June 6, 2019. This imagery was processed using structure-from-motion (SfM) photogrammetric techniques to derive high-resolution digital surface models (DSM), orthomosaic imagery, and topographic point clouds. In order to maximize the extent of...
Aerial imagery and structure-from-motion data products from UAS survey of the intertidal zone at Puget Creek and Dickman Mill Park, Ruston Way, Tacoma, WA, June 2019 Aerial imagery and structure-from-motion data products from UAS survey of the intertidal zone at Puget Creek and Dickman Mill Park, Ruston Way, Tacoma, WA, June 2019
An unmanned aerial system (UAS) was used to acquire high-resolution imagery of the intertidal zone at Puget Creek and Dickman Mill Park in Tacoma, Washington on June 3, 2019. This imagery was processed using structure-from-motion (SfM) photogrammetric techniques to derive high-resolution digital surface models (DSM), orthomosaic imagery, and topographic point clouds. In order to maximize...
