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 <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2010-072-FA>
Purpose:
These raw navigation data are included as an archive documenting the survey area surrounding Muskeget Channel, Massachusetts and the instrumentation used to manage the ship's navigation.

Data_Quality_Information:
Attribute_Accuracy:
Logical_Consistency_Report:
These are the original raw data files recorded by the HYPACK navigation software. No additional checks or corrections have been made to these files.
Completeness_Report:
These files represent four of the five global positioning systems used on the R/V Rafael during cruise 2010-072-FA. The GPS data recorded to HYPACK include the following receivers: a Novatel DLV3 (RTK), Communications Systems International (CSI), Inc. LGBX Pro (DGPS), an Ashtech Zxtreme (RTK), and a Garmin 5312 (echosounder for boat navigation). An additional antenna and receiver for the Coda Octopus F180 was used for navigation for the Swath interferometric and attitude data, and imported directly into SwathPlus without being logged in HYPACK. The Novatel DL-V3 (RTK) was used to acquire z-values for tidal corrections to the bathy. The Ashtech Z-extreme (RTK) was used for redundancy and recorded to HYPACK, but was not recorded for any instrument.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Positions of the ship (HYPACK line nav.) were determined using a Communications Systems International (CSI), Inc. LGBX Pro differential global positioning system (DGPS) antenna mounted above the cabin on the R/V Rafael. Swath bathymetry, continuous sound velocity at the sonar head, and attitude data were determined using a CodaOctopus F180 DGPS antenna mounted on a rigid, vertical pole aproximately 3-m above the swath transducers. A Novatel DL-V3 Real-Time Kinematic (RTK) and an Ashtech Z-xtreme antenna, mounted above the swath transducers, were used to acquire water-level heights for tidal corrections. A Garmin 5312 was used to drive the boat and monitor water depths. All DGPS data are assumed to be accurate to within + or - 1 to 2 meters.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Vertical (RTK) heights were collected with a Novatel receiver and sn Ashtech Z-Extreme receiver, then recorded to HYPACK Survey software. RTK positions were used to post-process tidal corrections for bathymetry data (using the Novatel heights). RTK positional accuracy is sub-meter. EC1 depth values were collected with a Furuno FRS 1000 plotter/radar/sounder, which has an assumed vertical accuracy of 0.5 meters.

The National Marine Electronics Association (NMEA) strings present in the HYPACK file are the $GPVTG, $GPZDA, $SDDPT, $GPGGA and $GPHDT. These are defined as follows:
$GPGGA is GPS fix data in the format "$GPGGA, t, lat, lath, long, longh, q, sat, h, a, M, alt, M, t2, refcheck" where t=time in UTC in the format hhmmss.ss; lat=latitude in the format ddmm.mmmmmm; lath= N or S indicating the latitude hemisphere; long=longitude in the format dddmm.mmmmmm; longh=E or W indicating the hemisphere; q=fix quality where 0=fix not available or invalid; 1=GPS fix; 2=Differential GPS fix; 3=GPS PPS Mode fix; 4=RTK fix; 5=RTK float; sat=number of satellites; h=Horizontal Dilution of Precision (HDOP); a=Antenna altitude above mean sea level (geoid); M= units of antenna altitude in meters; alt=height of geoid above WGS84 ellipsoid; M=units of geoidal height in meters; t2=time since last DGPS update; refcheck=DGPS reference station id and the checksum.
