Description:

Abstract:

These data are a part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. The work was conducted in collaboration with the Stellwagen Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited a total of 169 locations on Stellwagen Bank during three separate surveys from September 2020 to August 2021. During these surveys a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties including temperature, salinity, density, and fluorescence.

Purpose:

These navigation data are provided in three different formats: raw data in the original collected format (*raw.csv) as an archive of the navigation data files acquired during the survey as well as in reformatted CSV and XLSX formats. The reformatted files add additional information, and most significantly provide the navigation in decimal degrees.

Data_Quality_Information:

Logical_Consistency_Report:

The navigation was exported from the ship's navigation system by the R/V Auk's crew at the end of each cruise and given to the chief scientist. This raw navigation is in $GPGGA format. GGA is a National Marine Electronics Association (NMEA) sentence for Global Positioning System (GPS) fix data that includes time, position and fix related data for a GPS receiver. These raw navigation files were then parsed and reformatted to remove extraneous GPS information and clipped to exclude the transit portion of the navigation data (between the port and the study area). This dataset includes both the raw and reformatted navigation.
The original raw navigation filenames are in the format AUKYYYYYYY_XXXX_UTC_nav_raw.csv where YYYYYY is the field activity identifier (for example 2020012), and XXXX is the day of navigation (for example 24sep2020). All of the raw navigation files have the CSV file extension. The filenames of the reformatted navigation are in the format AUKYYYYYYY_station_nav_log_XXXX_UTC where YYYYYYY is the cruise ID (for example 2020012), and XXXX is the day of navigation (for example 24SEP2020); the file extension is either XLSX or CSV.
All the field activities were conducted on the Stellwagen Bank National Marine Sanctuary's research vessel, R/V Auk. Although these data represent three separate field activities, the set-up and acquisition on all the cruises is consistent with the exception of the navigation - which was sometimes acquired at 2-second intervals and sometimes at 5-second intervals.

Completeness_Report:

The raw navigation files represent all the navigation acquired on the cruises, including transit lines. These files are the original files handed over to the scientist from the ship personnel. The reformatted navigation files do not include the transit navigation between the port and the study area. No other navigation fixes were removed, so the data could include bad navigation fixes, missing fixes, and duplicates. The bounding coordinates represent the extent of the raw navigation data. The ranges of values in the entity and attribute section are from the reformatted navigation with the transit navigation fixes removed.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30 GPS receiver) in geographic coordinates (World Geodetic System of 1984 [WGS 84]) with a horizontal accuracy of 10 m. Field activity 2020-012-FA acquired navigation at two-second intervals on September 24 and five-second intervals on September 25. Field activity 2021-016-FA acquired navigation at a two-second interval. Field activity 2021-017-FA acquired navigation at a two-second interval. The navigation antenna was located 5.3 m forward of the SEABed Observation and Sampling System (SEABOSS) deployment location. This offset was not accounted for in the navigation acquisition so navigation fixes represent the antenna location.

Process_Description:

Raw CSV files: AUKYYYYYYY_XXXX_UTC_nav_raw.csv
The files *_raw.csv are the GGA strings of the raw navigation recorded on the ship each day. The first row in each file describes the file.

For the remaining rows, the format of the columns of information is as follows:

$GPGGA, Coordinated Universal Time (UTC) in the format HHMMSS, latitude (DDMM.MMMM), latitude hemisphere, longitude (DDMM.MMMM), longitude hemisphere.
Data were collected from 2020 to 2021 with the process date representing the most recent acquisition year.

Process_Description:

Reformatted XLSX files: AUKYYYYYYY_station_nav_log_XXXX_UTC.xlsx
The GGA strings have the latitude and longitude in the degrees decimal minutes format DDMM.MMMM with the hemisphere indicated (N for North and W for West). These data were brought into an Excel spreadsheet and converted to decimal degrees using the following formula examples:
latitude: (4211.9672-4200)/60+(42) to give 42.19945 decimal degrees
longitude: ((7043.2105-7000)/60 + 70) * -1 to give -70.72018 decimal degrees with negative for western hemisphere
Additional fields of information were added to the spreadsheet and are defined in the entity and attribute section, as well as within the header information in each spreadsheet. The first row is an explanation header, the second row contains descriptive column headers, and the third row contains brief column headers that are compatible with importing the data into a GIS.
The reformatted version of the navigation excludes the transit navigation between the port and the study area.
The data were reformatted shortly after collection, with data collection occurring from 2021 to 2021. The process date represents the most recent acquisition year.

The XLSX spreadsheet was opened in Microsoft Excel (O365). The first row (the explanation header) and the second row (descriptive column headers) were deleted and the third row (brief column headers that are compatible with importing the data into a GIS) was retained. Then the spreadsheet was exported as an MS-DOS CSV file with the same prefix filename as the Excel file.
