Surveys of the bathymetry and backscatter intensity of the sea floor south of Long Island, New York, were carried out in November 1998 using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard ship Frederick G. Creed. The purpose of the multibeam echosounder surveys was to explore the bathymetry and backscatter intensity of the sea floor in several areas off the southern coast of Long Island along the 20-meter isobath. Survey areas offshore of Fire Island Inlet, Moriches Inlet, Shinnecock Inlet, and southwest of Montauk Point were about 1 kilometer (km) wide and 10 km long. The area was mapped by the U.S. Geological Survey with support from the Canadian Hydrographic Service and the University...
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The elevation contour data was created based on bathymetry obtained in the meander reach collected in about a one month period extending from 6/3/2010 - 6/19/2010. This subset data extends from river kilometer designator 228 upstream to 237. Similar methods used to collect and process the bathymetry are described in Fosness (2013). The contours were created from a surface raster (also referred to as digital elevation model) of the...
These data are high-resolution bathymetry (riverbed elevation) in ASCII XYZ format, generated from the June 2, 2017, hydrographic survey of the Gasconade River near structure A3787 on U.S. Highway 50 at Mount Sterling, Missouri, to help identify possible effects from extreme flooding on May 1-2, 2017. Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which consists of a multibeam echosounder (MBES) and an inertial navigation system (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the river along planned survey lines distributed throughout the reach. Data collection software integrated and stored the depth data from the MBES and...
These data are high-resolution bathymetry (river bottom elevation) in XYZ format, generated from the February 14, 2017, topographic and hydrographic survey of the Des Plaines River in an area centered approximately 0.3 miles downstream of Brandon Road Lock and Dam at Joliet, Illinois. Hydrographic data were collected using a multibeam echo-sounder (MBES) with integrated inertial navigation solution (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the river along survey lines distributed throughout the area. Data collection software integrated and stored the depth data from the multibeam sonar and the horizontal and vertical position and attitude data of the vessel from the INS...

In 2009, the Kootenai Tribe of Idaho released and implemented the Kootenai River Habitat Restoration Master Plan. This plan aimed to restore, enhance, and maintain the Kootenai River habitat and landscape to support and sustain habitat conditions for aquatic species and animal populations. In support of these restoration efforts, the U.S. Geological Survey, in cooperation with the Kootenai Tribe of Idaho, conducted high-resolution...

The substrate enhancement pilot project (SEPP) extent GIS layer represents an area where an artificial substrate will be placed. The artificial substrate, consisting of a mixed size class of gravel, is aimed at providing a more suitable substrate for sturgeon eggs and early-life rearing habitat. The location of the SEPP extent was created by analyzing the egg-mat network, bathymetric features, surficial sediment facies, and streamflow...

The surficial bed-sediment facies, herein after referred to as the sediment facies, quantitatively describes the dominant sediment substrate on the surface of the river bed. Sediment facies categories were based on the grain size distribution of Wentworth (1922) which included the following ranges or combination of ranges: gravel (2-64mm), sand (0.063-2mm) and silt/clay (less than 0.063mm). An underwater video monitoring system UVMS...
