The field program was a cooperative effort between the USGS Coastal and Marine Geology Team of the Geologic Division and the USGS Columbia River Research Laboratory of the Biological Resources Division. The data collection was completed aboard the R/V ESTERO during September 13-27, 2000. The interest in sediment accumulation in the reservoir was two-fold. First, it was unknown how effective this reservoir was as a sediment trap to material that otherwise would have been transported down-river to the estuary and eventually to the ocean. The recent erosion of beaches along the Washington coast has been attributed to a decreased contribution of sediment from the Columbia River to the coastal system due to the damming of the river. Second, sediment accumulation on the floors of reservoirs along the Columbia River has been suggested to be diminishing salmon spawning grounds. The extent of changes in habitat since construction of the John Day Dam, however, had not been documented. Common data sets were needed to address both of these questions, and for these reasons this geophysical and sampling program was undertaken.This shapefile is intended to provide information as to what the floor of the John Day Reservoir looks like.David C.

This system was patterned after the SeaBOSS system in Woods Hole, MA. They system used a Van Veen grab sampler, and had a video camera mounted on the frame.The VHS tapes from this cruise were displayed on a flat-screen monitor and photographs were taken of theonitor using a Nikon Coolpix-5000 digital camera. It was attempted to take the picture near the time when the sediment sample was actually acquired, but this was not always possible. The only navigation available for these data were the actual sample points, so the imagery is located near, but not exactly where the navigational fixes are.These digital photographs were imported to Corel PHOTO-PAINT version 11 where the images were cropped, converted to black and white images, and enhanced to improve image contrast.All sample locations were treated the same.Represents all the locations where a bottom sample was recovered.10 mThe navigational system has an accuracy better than 10m, but because the data acquisition system was towed, this reduces the navigational accuracy.
