Description:
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Connecticut Department of Energy and Environmental Protection (CT DEEP), is producing detailed geologic maps of the coastal sea floor. Bathymetry and sidescan-sonar imagery, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities in Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During April-May 2009 NOAA completed hydrographic survey H12013 offshore of the entrance to the Connecticut River, and during November 2009 and April 2010 bottom photographs and surficial sediment data were acquired as part of two ground-truth reconnaissance surveys of this area. Two interpretive data layers were derived from the multibeam echo-sounder and the ground-truth data used to verify them. For more information on the ground-truth surveys see: <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-059-FA> and <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2010-010-FA>
Purpose:
The purpose of these data is to provide the navigation for the SEABOSS operation portion of USGS cruise 2010-010-FA as recorded by CSI LGBX Pro Differential Global Positioning System (DGPS) with HYPACK software. This provides an archive of the original navigation as well as allowing others to reprocess the navigation for their purposes.

Process_Description:
A USB thumb drive was used to transfer the text navigation files from the computer running the HYPACK navigation software. The original HYPACK navigation files are stored in a single folder. The filenames are in the format of linenumber_starttime.julianday. Since we weren't surveying any previously loaded lines, the "linenumber" is always 000. An example filename is 000_1343.315 which reflects line 000, start time 1343 and Julian day 315. The times in the filename reflect UTC (Coordinate Universal Time) times.

Overview_Description:
Entity_and_Attribute_Overview:
The times recorded in the navigation file are in UTC. Keywords and the information they provide are as follows, but slightly different information was recorded on the two days and not all keywords or elements may appear in all files.

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: Indicates that the lines with device designation 0 are lines of CSI LGBX Pro DGPS data.
OFF 1: device offsets for device 1 - see description above (no offset for device 1 used during this data collection)
DDT 1: unknown HYPACK header element present in jd108 with value SYN
DEV 2: Indicates that the lines with device designation 2 are bathymetry values.
OFF 2: device offsets for device 2 - see description above. A draft of 0.5 meters for the transducer during this data collection.
USR: User information in the format u r l k, where u=user name, r=reseller, l=license type, k=key number. Present in jd107
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 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 location - in the format "POS dn t x y" where dn=device number; t=time tag (seconds past midnight); x=easting; y=northing. On this cruise these values are in UTM, Zone 18, WGS84.

Not present on jd107.
GYR: Gyro Data (heading) in the format "GYR dn t h" where dn=device number; t=time tag (seconds past midnight); h=shipheading angle.
MSG: Message string in the format "MSG dn t message" where dn=device number; t=time tag (seconds past midnight); message is the message sent from the device. On this cruise, four different messages were sent from the DGPS: $GPVTG, $GPZDA, $SDDPT and $GPGGA. These will be defined later.
FIX: events marked by the user in the format "FIX dn t event number" where dn=device number (typicall 99 because there is no device for manual events); t=time tag (seconds past midnight); event number=event number such as 1, 2, 3, 4. Present in jd107, but not in all files.
The NMEA strings present in the HYPACK file are the $GPVTG, $GPZDA, $SDDPT, and $GPGGA. These are defined as follows.
$GPVTG is track made good and ground speed in the format "$GPVTG, t, T, m, M, n, N, k, K refcheck" where t=true course made good over ground, degrees; T indicates the previous number refers to true course; m=magnetic course made good over ground, dgrees; M indicates the previous number refers to magnetic course; n=ground speed; N indicates the previous number refers to Knots, k=ground speed; K indicates the previous number refers to Kilometers per hour, refcheck= checksum at the end of the string with the first character an *.
$GPZDA is UTC Date/Time and local time zone offset in the format "$GPZDA, hhmmss.ss,dd,mm,yyyy, xx, yy checksum" where hhmmss.ss= time in UTC; dd=UTC day; mm=UTC month; yyyy=UTC year; xx=offset to local time zone in hours; yy=offset to local time zone in minutes;checksum ***on this cruise the navigation computer was set to UTC time so the $GPZDA string indicates zero time offset.
$SDDPT is water depth relative to the transducer in mgers in the format "$SDDPT, data_meters, offset_meters, checksum
$GPGGA is GPS fix data in the format "$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 longitude hemisphere; q=fix quality where 2 is a DGPS fix; 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.
