Description: Abstract: Accurate data and maps of sea-floor geology are important first steps toward protecting habitat, delineating marine resources, and assessing environmental changes due to natural or human effects. Initiated in 2003, the primary objective of the Geologic Mapping of the Massachusetts Sea Floor program is to develop regional geologic framework information for the management of coastal and marine resources. The project is focused on the inshore waters (5–30 meters deep) of Massachusetts. This dataset is from U.S. Geological Survey (USGS) sampling survey 2011-015-FA (September 9–16, 2011) by the USGS Woods Hole Coastal and Marine Science Center and the Massachusetts Office of Coastal Zone Management with partners from the Massachusetts Division of Marine Fisheries and the U.S. Environmental Protection Agency aboard the ocean survey vessel Bold. During the survey, surficial sediment samples and bottom still and video imagery were collected in Cape Cod Bay, Buzzards Bay, and Vineyard Sound; south of Martha's Vineyard; and south and east of Nantucket, Massachusetts. Purpose: These navigation data are provided as an archive of the navigation data files acquired during USGS survey 2011-015-FA offshore of Massachusetts in Cape Cod Bay, Buzzards Bay, and Vineyard Sound; south of Martha's Vineyard; and south and east of Nantucket. Supplemental_Information: During the survey, bottom still and video imagery was taken at most stations (see shapefiles 2011-015-FA_photos.shp and 2011-015-FA_videos.shp available from the larger work citation; see the Coastal and Marine Geology Program Video and Photograph Portal to view the bottom videos [Golden and others, 2015; link available from the cross-reference citation]). Physical sediment samples were also collected at many stations and analyzed for grain size (see shapefile 2011-015-FA_samples.shp available from the larger work citation) and benthic infauna (see report by the Massachusetts Office of Coastal Zone Management [2012] available from the cross-reference citation).

Logical_Consistency_Report: The original files were recorded by a Microsoft HyperTerminal session and were logged for each sampling watch. The GPGGA parsed navigation files were created by splitting and combining the original files for each Julian day of surveying based on Coordinated Universal Time (UTC; starting at time 000000, ending at 235959). The files include navigation data logged during the transits en route to, returning from, and between the sampling sites. In general, the navigation feed was continuous, even during breaks in the sampling survey, although some gaps in the navigation data may occur during the transit times. Records of well-formatted yet erroneous navigation fixes may occur but were not checked, removed, or corrected. Completeness_Report: These files represent all the navigation recorded by the Microsoft HyperTerminal session during USGS survey 2011-015-FA. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Navigation for survey 2011-015-FA used Differential Global Positioning System (DGPS). The recorded position of each navigation point is the position of the DGPS antenna on the survey vessel, not the SEABed Observation and Sampling System (SEABOSS) or Van Veen grab sampler. The antenna was at the top of the vessel's A-frame from which the sampler was deployed, within a few meters of the sampler. No layback or offset was applied to the recorded position. In addition to the +/- 3-meter offset, the sampler may drift away from the survey vessel when deployed to the sea floor. Based on the various sources of horizontal offsets, a conservative estimate of the horizontal accuracy of the video trackline and sediment sample locations is 3-10 meters and of the bottom still imagery is 5-20 meters (the still imagery has larger potential horizontal offsets due to camera time drift, although offsets are most likely within 3-10 meters). Lineage: Process_Step: Process_Description: DGPS navigation from a Garmin GPSMAP 76CSx receiver was logged through a Microsoft HyperTerminal (version 5.1) session on a Dell Latitude D820 laptop computer running Windows XP SP2 via serial cable. The DGPS was set to receive fixes at a two-second interval in geographic coordinates (World Geodetic System of 1984 [WGS 84]). Log files were saved for each sampling watch in ASCII text format. The filenames are in the format of [UTC date]_GPSout[UTC start time].txt. For example, filename Sept10_GPSout0127.txt represents the raw navigation logged beginning on September 10, 2011, at 01:27. Dates and times are recorded in UTC. This process step and the subsequent process step were performed by the same person, Seth Ackerman.

The raw navigation files were parsed for the GPGGA navigation string and CSV files of the parsed GPGGA navigation data by Julian day are also included in this dataset. These are the original files, so no corrections have been made to these files. The times recorded in the navigation files are in UTC. The NMEA strings and the information they provide are as follows: $GPGSV is data about the satellites in view. For example, "$GPGSV,3,3,12,25,14,257,44,26,33,166,49,29,39,305,48,46,32,214,45*7E" where: 3 = Number of sentences for full data 3 = Sentence 3 of 3 12 = Number of satellites in view 25 = Satellite Pseudo-Random Noise (PRN) number 14 = Elevation in degrees 257 = Azimuth in degrees 44 = Signal-to-Noise Ratio (SNR; higher is better) (The above four data fields may be repeated for up to four satellites per sentence. In the above example, they are repeated for four satellites.) *75 = Checksum data, always begins with * $GPGLL is geographic latitude and longitude data. For example, "$GPGLL,4122.0274,N,07101.3161,W,012706,A,D*54" where: 4122.0274,N = Latitude 41 degrees 22.0274 minutes North 07101.3161,W = Longitude 071 degrees 01.3161 minutes West 012706 = Fix taken at 01:27:06 UTC A = Data status (A = active, V = void) D = Mode indicator (A = Autonomous, D = Differential, E = Estimated, N = Data not valid) *54 = Checksum data $GPBOD is bearing origin to destination data. For example, "$GPBOD,045.,T,023.,M,DEST,START*01" where: 045.,T = Bearing 045 degrees True from "START" to "DEST" 023.,M = Bearing 023 degrees Magnetic from "START" to "DEST" DEST = Destination waypoint ID START = Origin waypoint ID *01 = Checksum data Note: The above example is from a different dataset. GPBOD strings were not transmitted during this survey and were therefore recorded as "$GPBOD,,T,,M,,*47" in the raw navigation files. $GPVTG is velocity made good and ground speed data. For example, "$GPVTG,299.3,T,314.6,M,9.1,N,16.8,K,D*10" where: 299.3,T = True track made good in degrees 314.6,M = Magnetic track made good in degrees 9.1,N = Ground speed, knots 16.8,K = Ground speed, kilometers per hour D = Mode indicator (A = Autonomous, D = Differential, E = Estimated, N = Data not valid) *48 = Checksum data $PGRME is a Garmin proprietary sentence about the estimated position error ("P" denotes proprietary, "GRM" is Garmin's manufacturer code, and “E” indicates the specific sentence type). For example, "$PGRME,2.4,M,2.8,M,3.7,M*26" where: 2.4,M = Estimated Horizontal Position Error (HPE), meters 2.8,M = Estimated Vertical Position Error (VPE), meters 3.7,M = Overall spherical equivalent position error, meters *26 = Checksum data $PGRMZ is a Garmin proprietary sentence with altitude information ("P" denotes proprietary, "GRM" is Garmin's manufacturer code, and “Z” indicates the specific sentence type). For example, "$PGRMZ,43,f,*1F" where: 43,f = Altitude, feet [Empty field] = Position fix dimensions (2 = user altitude, 3 = Global Positioning System [GPS] altitude) *1F = Checksum data Note: This sentence shows in feet, regardless of units shown on the display. For units with an altimeter, the altitude will be computed by the internal altimeter. $PGRMM is a Garmin proprietary sentence about the map datum ("P" denotes proprietary, "GRM" is Garmin's manufacturer code, and “M” indicates the specific sentence type). For example, "$PGRMM,WGS 84*06" where: WGS 84 = Currently active horizontal datum *06 = Checksum data $HCHDG is data about the magnetic heading, deviation, and variation. This string is used on Garmin eTrex Summit, Vista, and GPSMAP 76S receivers to output the value of the internal flux-gate compass. Only the magnetic heading and magnetic variation is shown in the message. For example, "$HCHDG,314.6,,,15.3,W*0C" where: 314.6 = Heading ,, = Deviation (no data) 15.3,W = Variation *0C = Checksum data $GPRTE is sent to indicate the names of the waypoints used in an active route. For example, "$GPRTE,1,1,c,*37" where: 1 = Total number of sentences for full data 1 = Sentence 1 of 1 c = Type (c = complete list of waypoints in this route, w = first listed waypoint is start of current leg) [Empty field] = Route identifier [Empty fields] = Waypoint identifiers (names) *37 = Checksum data $GPRMC is the recommended minimum GPS data. For example, "$GPRMC,012708,A,4122.0299,N,07101.3219,W,9.1,300.3,100911,15.3,W,D*2C" where: 012708 = Fix taken at 01:27:08 UTC A = Status (A = active, V = void) 4122.0299,N = Latitude 41 degrees 22.0299 minutes North 07101.3219,W = Longitude 071 degrees 01.3219 minutes West 9.1 = Speed over the ground in knots 300.3 = Track angle in degrees true 100911 = UTC date September 10, 2011 15.3,W = Magnetic variation in degrees D = Mode indicator (A = Autonomous, D = Differential, E = Estimated, N = Data not valid) *2C = Checksum data $GPRMB is the recommended minimum navigation sentence. For example, "$GPRMB,A,0.66,L,003,004,4917.24,N,12309.57,W,001.3,052.5,000.5,V*20" where: A = Data status (A = active, V = void) 0.66,L = Cross-track error in nautical miles (9.99 max), steer Left to correct (or R = right) 003 = Origin waypoint ID 004 = Destination waypoint ID 4917.24,N = Destination waypoint latitude 49 degrees 17.24 minutes North 12309.57,W = Destination waypoint longitude 123 degrees 09.57 minutes West 001.3 = Range to destination in nautical miles (999.9 max) 052.5 = True bearing to destination 000.5 = Velocity towards destination in knots V = Arrival alarm (A = arrived, V = not arrived) *20 = Checksum data Note: The above example is from a different dataset. GPRMB strings were not transmitted during this survey and were therefore recorded as "$GPRMB,A,,,,,,,,,,,,V,D*19" in the raw navigation files. $GPGGA is essential GPS fix data. For example, "$GPGGA,012708,4122.0299,N,07101.3219,W,2,10,0.8,13.1,M,-33.8,M,,*49" where: 012708 = Fix taken at 01:27:08 UTC 4122.0299,N = Latitude 41 degrees 22.0299 minutes North 07101.3219,W = Longitude 07 degrees 101.3219 minutes West 2 = Fix quality (0 = invalid, 1 = GPS fix, 2 = DGPS fix, 3 = Precise Positioning System [PPS] fix, 4 = Real Time Kinematic [RTK] fix, 5 = RTK float, 6 = estimated, 7 = manual input mode, 8 = simulation mode) 10 = Number of satellites being tracked 0.8 = Horizontal dilution of position 13.1,M = Altitude above mean sea level (geoid), meters -33.8,M = Height of geoid above WGS 84 ellipsoid, meters [Empty field] = Time in seconds since last DGPS update [Empty field] = DGPS station ID number *49 = Checksum data $GPGSA is overall satellite data.
