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 located around the western extent of the Elizabeth Islands includes high resolution bathymetry, acoustic-backscatter intensity, seismic-reflection, and navigation data. These data were collected during a nearshore cruise in September 2010 onboard the R/V Rafael using the following equipment: an SEA Ltd SwathPlus interferometric sonar (234 kHz), Klein 3000 dual frequency sidescan sonar, an Edgetech 424 chirp subbottom profiling system, and 4 GPS antennae. More information about the cruise 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 webpage: <http://quashnet.er.usgs.gov/data/2010/10003/>
Purpose:
These raw navigation data are included as an archive documenting the survey area surrounding the Elizabeth Islands, Massachusetts and the instrumentation used to manage the ship's navigation.

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. No HYPACK files were recorded on Julian day 258 (Sept. 15, 2010 ) due to weather conditions. Julian day 252 navigation is from instrument calibration.
Completeness_Report:
These files represent four of the five global positioning systems used on the R/V Rafael during cruise 2010-003-FA. The GPS data recorded to HYPACK include the following receivers: a Novatel DLV3 (RTK), Communications Systems International (CSI), Inc. LGBX Pro (DGPS), a Garmin 5312 (echosounder for boat navigation), and an Ashtech Z-extreme (DGPS). 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 was used for redundancy and recorded to HYPACK, but was not recorded as navigation for any instrument. The Novatel DL-V3 (RTK) was used only to acquire z-values for tidal corrections to the bathy. The RTK, x and y values were not used for any instrument navigation.

Horizontal_Positional_Accuracy_Report:
Positions of the ship (HYPACK line nav.), sub-bottom, and sidescan sonar 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) antenna, also mounted above the swath transducers, was used to acquire water-level heights for tidal corrections. A Garmin 5312 was used to drive the boat and monitor water depths. Additionally, an Ashtech Z-Extreme was also used to record positions to HYPACK, but these data were not logged to any instrument. All DGPS data are assumed to be accurate to within + or - 1 to 2 meters.

Raw navigation data were saved in HYPACK format. File name convention is LLL_TTTT.JJJ, where LLL is the HYPACK line number, TTTT is the 24 hour time for the beginning of the file, and JJJ is the Julian Day of data collection. Times were recorded in UTC (Coordinate Universal Time). Julian Day 253 is an exception to this naming convention. Due to generator trouble, the survey team was troubleshooting instrument function and data collection was abandoned for the day. The HYPACK lines that were collected were namedd S16.253, S15.253, and S14.253.

Process_Description:
Raw HYPACK (9.0.5.17) navigation files were transferred from the navigation acquisition computer to an external drive. The raw HYPACK navigation files are stored in separate directories indicating the acquisition Julian Day. The filenames in each folder are in the format of linenumber_starttime.julianday. For example, filename 004_0850.254 represents HYPACK line number 004, start time 0850, and Julian Day 254. Times are recorded in UTC (Coordinate Universal Time).

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.
