Description:
Abstract:
These data were collected under a cooperative agreement between the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHCMSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of seafloor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of coastal Massachusetts, primarily in water depths of 2-30 meters. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (<http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html>). The data collected in this study area are located in both Buzzards Bay and Vineyard Sound and are primarily in the shallow water areas around the eastern Elizabeth Islands and Martha's Vineyard, Massachusetts. The data include high resolution bathymetry, acoustic-backscatter intensity, sound velocity in water, seismic-reflection profiles, and navigation data. These data were collected during several cruises between 2007 and 2011 onboard the R/V Rafael using the following equipment: an SEA Ltd SwathPlus interferometric sonar (234 kHz), Klein 3000 dual frequency sidescan sonar, a boomer source and Geometrics 8-channel GeoEel streamer, a Knudsen 3200 subbottom profiling system, and 4 GPS antennae. More information about the cruises conducted as part of the project: Geologic Mapping of the Seafloor Offshore of Massachusetts can be found on the Woods Hole Coastal and Marine Science Center Field Activity webpages: <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2011-013-FA> <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-068-FA> <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2007-039-FA><http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2010-100-FA><http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2010-047-FA>

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 two of the three global positioning systems used on the R/V Rafael during cruise 2007-039-FA. The GPS data recorded to HYPACK include the following receivers: an Ashtech Zxtreme (RTK), and a Furuno 1000 (GPS/plotter and 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 Ashtech Z-extreme (RTK) was used for redundancy and recorded to HYPACK, but was not recorded as x,y navigation for any instrument. RTK vertical positions were used to post-process tidal corrections for bathymetry data.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Positions of the ship and water depths (HYPACK line nav.) were determined using a Furuno 1000 (GPS/Plotter and echosounder) antenna mounted above the cabin on the R/V Rafael. These GPS data are assumed to be accurate to within + or - 10 meters.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Real-Time Kinematic (RTK) heights were collected with an Ashtech Z-Extreme receiver, and recorded by HYPACK Survey software to HYPACK raw files. RTK vertical positions were used to post-process tidal corrections for bathymetry data. 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.

Overview_Description:
Entity_and_Attribute_Overview:
The times recorded in the navigation file are in UTC. Keyword definitions and the information listed below are comprehensive and not found in every file. The definitions are as follows:
FTP: The first record located at the top of the header used to identify the file format. VER: HYPACK version number.
INF: General survey information filled in by the data technician. This typically contains the survey participants, the vessel name, other agencies involved with the survey, and the location of the survey. The three numbers at the end refer to initial tide correction at start-of-line, initial draft correction at start-of-line and sound velocity from the navigation parameters.
FIL: Raw format file. In the HYPACK files this line suggests that the data were collected in Penobscott Bay, however, this is an inaccurate entry left over from a previous cruise.
ELL: Ellipsoid information. The name of the ellipsoid followed by the semi-major axis in meters and the flattening ration.
PRO: Project information record where TME indicates Transverse Mercator and the central meridian of -69 indicates UTM, zone 19.
DTM: Datum transformation record
GEO: Geoid model. Blank if not present.
HVU: Horizontal and Vertical Units (meters).
TND: Survey time and date in UTC.
DEV 0: Indicates that the lines with device designation 0 are lines of RTK-GPS data acquired with an Ashtech Zxtreme (rtk) receiver.
OFF 0: device offsets for device 0. Format of the value is OFF dn n1 n2 n3 n4 n5 n6 n7 where dn=device number; n1=starboard, port offsets where positive is starboard; n2=forward, aft offset where positive is forward; n3=height (antenna) or depth (transducer draft) offset - always positive; n4=yaw rotation angle where positive for clockwise rotation; n5=roll rotation angle where port side up is positive; n6=pitch rotation angle where bow up is positive; n7=device latency in seconds. No offset for device 0 during this data collection.
DEV 1: Although there is a heading for DEV 1, DEV 1 was not connected to any data source and therefore the driver was not used for this survey
OFF 1: device offsets for device 1 (no dev 1)
DEV 2: Indicates that the lines with device designation 2 are lines of Furuno FRS 1000 which is a radar/plotter and depth sounder.
OFF 2: device offsets (none used during this data collection)
DDT 2: identifies the device (2) that the computer clock is being synchronized to.
LIN: planned line data follows in the format "LIN nw" where nw=number of waypoints.
PTS: planned line waypoints; easting, northing in UTM zone 19N, meters.
LBP: planned line begin point; easting, northing in UTM zone 19N, meters.
LNN X: planned line name where X is the line name
EOL: end of planned line
EOH: end of header
The remaining elements have similar information in the first 3 columns. The first column will indicate the data type, the second column will indicate the device that recorded the information (e.g. 0 for Ashtech Z-Extreme receiver) and the third column is the time tag (seconds past midnight) that is also sometimes referred to as the latency. The remaining information on each line is specific to the data type.
POS: Position of the ship - in this case the antenna - in the format "POS dn t x y z" where dn=device number; t=time tag (seconds past midnight); x=easting; y=northing. On this cruise these values are in UTM, Zone 19N, WGS 84.

TID: Tide correction in the format "TID dn t dc" where dn=device number, t=time tag (seconds past midnight), dc = draft correction.
EC1: Echo Sounding (single frequency) in the format "EC1 dn t rd" where dn=device number; t=time tag (seconds past midnight); rd=raw depth in meters.
FIX: events marked manually by the user in the format "FIX dn t event_number" where dn=device number (typically 99 as there is no device for manual events); t=time tag (seconds past midnight); event_number=event number such as 1,2,3,4.
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 WGS 84 ellipsoid; M=units of geoidal height in meters; t2=time since last DGPS update; refcheck=DGPS reference station id and the checksum.
