Description:

Abstract:

These data were collected in a collaboration between the Woods Hole Oceanographic Institution and the U.S. Geological Survey (USGS). The primary objective of this program was to collect baseline bathymetry for Muskeget Channel, Massachusetts, and identify areas of morphologic change within and around the channel. Repeat surveys in select areas were collected one month apart to monitor change. These data were collected to support an assessment of the effect on sediment transport that a tidal instream energy conversion facility would have within Muskeget Channel. Accurate data and maps of sea-floor topography are important first steps in monitoring bedform migration, fish habitat, marine resources, and environmental changes due to natural or human impacts. The data include high-resolution bathymetry, acoustic-backscatter intensity, sound velocity in water, and navigation data. These data were collected during two surveys between October 2010 and November 2011 onboard the research vessel (RV) Rafael using an SEA Ltd. SwathPlus interferometric sonar (234 kilohertz). More information about the cruise can be found on the Woods Hole Coastal and Marine Science Center field activity Web page at https://cmgds.marine.usgs.gov/fan_info.php?fan=2010-072-FA.

Purpose:

This dataset is used to display the raw data, profile image, and locations of sound velocity data collected during a USGS cruise within the vicinity of Muskeget Channel, MA. The information contained within the sound velocity profile is needed to adequately account for refraction artifacts that may be present within raw swath bathymetric data. This dataset can hyperlink to graphs of the sound velocity profile at each station location, as well as location in easting and northing (UTM, Zone 19N, WGS84, meters), time of day and date.

Data_Quality_Information:

Logical_Consistency_Report:

All sound velocity profiles were acquired with the same instrument; an Applied Microsystems SV plus v2.

Completeness_Report:

All sound velocity profiles collected during 2010-072-FA are included here as text, images, and a shapefile of the locations.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Differential Global Positioning System (DGPS) navigation data were acquired with a Communications Systems International (CSI), Inc. LGBX Pro receiver and recorded with HYPACK (www.hypack.com). The CSI received positions from a DGPS antenna located on the port, aft roof of the R/V Rafael cabin. Ship location was used for the sound velocity deployments. The SV plus v2 sound velocity profiler was hand deployed. Once the system reached bottom, positions were read from HYPACK and stored in the survey log. DGPS accuracy is 1 to 3 meters, depending on the distance from a US Coast Guard coastal repeater station. However, offsets from the location of hand-deployment and the DGPS antenna were not measured, and the ship is allowed to drift during deployment which can last several minutes depending on water depth. The horizontal accuracy of the sound velocity locations is considered to be +/- 50 meters.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Water depth of the sound velocity profile location is recorded from the fathometer. Assumed vertical accuracy of the shipboard fathometer on the R/V Rafael is about 0.25 meters. However, vessel drift during SVP deployment and recovery could add an additional meters of change in water depth at the location of deployment. Water depth recorded in the shapefile attribute field should be considered an approximation of water depth at the location of SVP deployment. Water depth in the sound velocity profiles is extracted from the recorded sound velocity profile after recovery. Depth (as pressure in dbars or meters) is recorded as the sound velocity profiler is lowered through the water column and downloaded after the instrument is recovered. Data are stored in ASCII text files. Depth values in the profile text and images should be accurate to within 1 meter.

Sound velocity profiles are acquired in order to measure the speed of sound in the water column during survey operations. This information is used to help correct any refraction artifacts that may be present within the swath bathymetric data due to unaccounted for changes in the speed of sound throughout the water column.

Process_Step:

Process_Description:

Profiles were collected at least once during each survey day, and multiple times per day when the data suggested significant stratification within the water column. Sound velocity casts were collected using an Applied Microsystems SV Plus v2 instrument (see <http://www.amloceanographic.com> for details). At each station, the SV plus 2 was hand deployed and slowly lowered to the seafloor. The SV plus v2 was monitored by a member of the science party and as the instrument made contact with the seafloor, the position (i.e. location) and depth (based on fathometer) was recorded in the lab using HYPACK navigation software. The position was then manually recorded within the cruise log and SWATHplus acquisition software. Upon recovery, the SV plus was connected to an onboard computer via serial port in order to download data using the SV plus v2 communications software, SmartTalk. Raw SVP data (text format) were edited using awk to remove the header information and remove data columns except water depth (pressure) and speed of sound

Process_Description:

The data were then exported in text format and imported to MATLAB (version R2011a). Graphs of the sound velocity profile (Pressure vs. speed of sound) at each station were created within MATLAB and exported as *.png files. A MATLAB script is included in the svp_data.zip file that creates PNG image profiles from the sound velocity text files.

The location of each sound velocity profiles recorded in the survey log in eastings and northings (UTM, Zone 19N, meters, WGS84) was saved to a comma-separated value file (*.txt) along with station number, water depth at station, julian day and time, and survey id. The comma-separated text file was then imported to ArcMap 9.3 using 'Add XY data' and saved as points (UTM WGS84 Zone 19N) in the Esri shapefile format. Finally, the data were reprojected from UTM Zone 19N, WGS84 to GCS WGS84 using ArcToolbox

Process_Step:

Process_Description:

Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Attempted to modify http to https where appropriate. Added the DOI link in the Identification section - both as the first link and as part of the Larger Work citation. Removed LIDAR bounding coordinates - an artifact of Esri and MP processing. Fixed browse graphic link. The source information was incomplete and had to be modified to meet the standard. Minor fixes to the attribute format for some attributes were needed. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
