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 log books provide a record of information recorded in the field. The log books for each field activity are provided as PDF files in two versions. One version with OCR (object character recognition) applied to the file (indicated in the filename) and the other without OCR due to the loss of visual clarity and resolution when OCR was applied. The OCR files are included to assist users with vision limitations.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The latitude and longitude of stations recorded in the log book were later adjusted to match the latitude and longitude recorded at that time in the GPS navigation file.
Logical_Consistency_Report:
These are the log books maintained during data acquisition on three U.S. Geological Survey field activities. The filename of the PDF indicates which activity the log covers. One cruise had two logbooks (2021-017-FA) represented by vol1 and vol2 as part of the filename. All the field activities took place 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. The latitude and longitude of stations recorded in the log book were later adjusted to match the latitude and longitude recorded at that time in the GPS navigation file.
Completeness_Report:
The PDF files represent all the acquisition logs maintained by the USGS during these surveys.
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. Cruise 2020-012-FA acquired navigation at two-second intervals on September 24 and five-second intervals on September 25. Cruise 2021-016-FA acquired navigation at a two-second interval. Cruise 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 antenna location. The entries in the log book are transcribed manually, so some errors could be associated with that process.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Water depth relative to the local sea surface was determined using a Simrad ES60, 120 kHz, single beam echosounder using a dual frequency 120-25 kHz transducer, which detects the seabed to a depth of 800 m. Depth values were rounded to the nearest meter to account for ship motion. The entries in the log books are transcribed manually, so some errors could be associated with that process. The depth is relative to the transducer location, no adjustment was made for tides or transducer depth.

Process_Step:
Process_Description:
The log books were maintained during the surveys by the chief scientist. These log books contain notes and information pertaining to the seabed video, CTD data, and sediment sample acquisition. Information includes date and time of acquisition, as well as water depth, latitude, and longitude. Additional information regarding observations from the video such as seabed description and fauna are noted in the log books. The survey data were collected with the SEABOSS. See the cross-references for a description of SEABOSS (Blackwood and Parolski, 2001; Valentine and others, 2000). The latitude and longitude of stations recorded in the log book were later adjusted to match the latitude and longitude recorded at that time in the GPS navigation file.
Data were collected from 2020 to 2021 with the process date representing the most recent acquisition year.

Process_Step:
Process_Description:
The PDF files were opened in Adobe Acrobat Pro DC version 2021.011.20039 to apply OCR (optical character recognition) to the files so that the documents are more 508 compliant. The following steps were taken to apply OCR: from the Tools menu select Scan and OCR; from the Scan and OCR toolbar, select Enhance - scanned document; select all pages and check Recognize Text; from the settings deselect Apply Adaptive Compression and set the slider to High Quality (without these settings, the quality of the scan is greatly reduced once OCR is complete); remaining settings as default values; and finally clicked the enhance button to process the PDF. Because much of the content is handwritten, the OCR optimization is only partially successful. Both the original PDF files as well as the OCR PDF files are available. The OCR procedure reduces the resolution slightly in the files, hence the reason for also providing the original files.
