        abstract:  This dataset contains current velocities taken by lowered ADCP during research cruise conducted on the research vessel Hugh R. Sharp from late August to early September 2017 by the University of Rochester (J. Kessler) and the U.S. Geological Survey (USGS; C. Ruppel) with funding from the U.S. Department of Energy (DE-FE0028980 and DE- FE0026195, respectively) focused on water column methane dynamics in the U.S. Mid-Atlantic Bight between just north of Washington Canyon and Cape Hatteras, mostly at water depths from ~100 m to 1500 m. A critical component of this study was the acquisition of water column data along transects arrayed roughly perpendicular to the shelf-break and from shallow to deeper depths on the uppermost continental slope. This dataset reports lowered ADCP (LADCP) measurements made simultaneous with CTD casts on these transects. The LADCP data were collected using approved LADCP protocols and equipment using an instrument owned and operated by the USGS and mounted on the CTD carousel during most CDT casts. The LADCP data were combined with other cruise datasets, including positional information from the CTD files and conventional ADCP data collected by R/V Hugh R. Sharp's hull-mounted instrumentation, to produce current speed vectors as a function of depth for most of the CTD casts. A recent version of the LADCP-community-standard Lamont-Doherty Earth Observatory Matlab-based processing package (version IX_13) was used to process the LADCP data. The files in this release include an informational header providing date, time, and location of the CTD casts for the corresponding LADCP measurements and the processed data for the depth below sea surface and calculated current velocity components. Data are in text format.
        purpose:  These data were collected to support a study of water column methane concentrations, methane carbon isotopic signatures, and oxidation rates on the U.S. Mid-Atlantic margin at distinct locations along transects down the upper continental slope in areas with known seafloor gas seepage and in background areas with no seepage.

                description:  Parameter or Variable: CURRENT SPEED - EAST/WEST COMPONENT (U) (calculated); Units: m/s; Observation Category: in situ; Sampling Instrument: LADCP; Sampling and Analyzing Method: Raw data were collected by USGS researchers C. Ruppel and G. Hatcher on the R/V Sharp, with shoreside support from M. Martini, J. Borden, and K. Rosenberger from the USGS. The measurements were made using a Teledyne RDI Workhorse 300 kHz ADCP unit #WH2624 (owned by USGS Woods Hole) in a deepwater housing mounted within the outer ring but outside the bottles on the R/V Sharp's CTD carousel as part of most CTD casts during the cruise. No LADCP was run for CTD#8, which was conducted in an estuary. No LADCP data were obtained for CTD#3. The LADCP data reported here correspond to CTD #5 through #29, with the exception of #8, #14, and #21. Before the cruise, the ADCP’s magnetic compass was calibrated by J. Borden in parking lot at the Marine Operations Facility at USGS Woods Hole. Only one battery pack was used for the entire cruise, and the pressure case was never opened. Therefore, Borden’s calibration should be sufficient. The ADCP was mounted on the carousel downward looking, and a command file written by J. Borden at USGS Woods Hole was used to record data. Data were collected at 1 s per ping and 1 ping per ensemble, with bin size set to 800 cm and max radial water velocity set at 176 cm/s. Data were recorded with speed of sound assigned as 1500 m/s and in the narrow band mode for the ADCP, but with 10% extended range. The USGS used a NTP server to set LADCP time to GPS satellite time before each CTD cast. After a cast, data were downloaded to a PC laptop. Processing of the LADCP data to derive meaningful current speed vectors and depths was completed by Angel Ruiz-Angulo using the Lamont Doherty Earth Observatory (LDEO) software package, version IX_13 (Thurnherr, 2011), incorporating bottom tracking, GPS (from related CTD time series), and supplementary data from the hull mounted RDI Workhorse 300 kHz ADCP to constrain the inversion model. CTD data can be accessed at: https://accession.nodc.noaa.gov/0209090. Original LADCP data are available from the USGS (cruppel@usgs.gov).; Data Quality Method: Calculated data were assessed for reasonableness based on expected values of current velocities. Maximum error in component velocities is set at 0.5 m/s. Maximum variability in angular velocity w is set at 0.2 m/s. During the cruise, diagnostic programs were run on the LADCP unit prior to taking any measurements on each day. The LADCP passed all of these tests every time they were attempted. The LADCP unit at times interfered with the R/V Sharp’s altimeter (200 kHz) on the CTD carousel. This is a known issue documented in Thunherr et al.’s guide to LADCP (IOCPP report 14, ICPO Pub Series 134, 2010, “The GO-SHIP Repeat Hydrography Manual: A Collection of Expert Reports and Guidelines”)…Publication is called: “A Manual for Acquiring Lowered Doppler Current Profiler Data”..

            description:  Acoustic Doppler Current Profiler The Acoustic Doppler Current Profiler (ADCP) measures currents beneath a ship while underway. Sound signals sent from the moving ship bounce back to receivers aboard the ship. This provides a profile of water movement relative to the ship-precise modern navigation, allowing the ship's motion to be subtracted from the data. These devices are also used on moorings and profilers and, along with acoustic backscattering, measure animal biomass. Particles in the path of the sound waves, mostly plankton, reflect a small part of the sound energy back toward receivers, allowing researchers to make remote estimates of the sizes and numbers of animals present in the water column. Before the 1970's, the most technologically advanced instrument used to measure water velocity was known as a Doppler speed log. This evolved into the first commercial ADCP, produced in the mid-1970's, which used averaging. Later in the 1970's, the first vessel-mounted ADCP was developed to measure water velocity more accurately and to allow measurement in range cells over a depth profile. As instruments evolved, so did new techniques in Doppler signal processing. Initially, Doppler speed logs used simple analog signal processing methods, which are still used in some commercial speed logs today. However, the first ADCPs incorporated analog-to-digital signal conversion over a narrow communication bandwidth. Around 1990, this technique was developed into broadband signal processing. Since then, broadband ADCPs have been able to generate very accurate, real-time velocity measurements.
