Digital elevation models of the State Route 530 landslide near Oso, Washington, July 2014 to July 2015 Digital elevation models of the State Route 530 landslide near Oso, Washington, July 2014 to July 2015

Digital elevation models of the SR530 Landslide, created using structure from motion photogrammetry. These surveys were performed at irregular intervals between July 1, 2014 and July 7, 2015. Due to the photogrammetric methods used to collect these surveys, there may be substantial artifacts near the edges of the surveys, in areas of vegetation, or over extents of bare water, and should...

Topographic and bathymetric surveys of the Nooksack River completed 2015 Topographic and bathymetric surveys of the Nooksack River completed 2015

Bathymetric and topographic data on the mainstem Nooksack River, Whatcom County, Washington were collected in the fall of 2015 as part of a study on sediment transport and channel change. Bathymetric data was collected from the river's mouth to river mile (RM) 28, near Nugent's Corner. Topographic data is available from RM 17, near the town of Lynden, to RM 37, near the confluence of the...

Sediment chemistry and sediment toxicity in wadable streams across the Midwestern United States, 2013 Sediment chemistry and sediment toxicity in wadable streams across the Midwestern United States, 2013

These data present chemistry and toxicity results from freshwater stream sediments collected from 99 wadable stream sites across eleven states in the Midwestern U.S. as one component of a larger USGS study in the summer of 2013. This data presents a selected suite of chemistry collected at these sites (PAHs, Organochlorines, PCBs, Trace Elements, and current use pesticides) used in...

Trace elements concentrations in pore water and surface water near the sediment-water interface in the Upper Columbia River, Washington (2015) Trace elements concentrations in pore water and surface water near the sediment-water interface in the Upper Columbia River, Washington (2015)

Smelter slag containing copper and other trace elements is widespread in riverbed sediment of the upper Columbia River (UCR) of the United States. To evaluate potential risk to aquatic life concentrations of copper and other trace elements were measured in shallow pore-water and in river water samples collected near the sediment-water interface. Samples were collected using an in-situ...
