The interpretive datasets and source information presented here are for quadrangle 5, which is one of 18 similarly sized segments of the 3,700 square kilometer (km2) SBNMS region. The seabed of the SBNMS region is a glaciated terrain that is topographically and texturally diverse. Quadrangle 5 includes the shallow, rippled, coarse-grained sandy crest and upper eastern and western flanks of southern Stellwagen Bank, its fine-grained sandy lower western flank, and the muddy seabed in Stellwagen Basin. Water depths range from <25 m on the bank crest to ~100 m in the basin. The data presented here for quadrangle 5 are the foundation for Scientific Investigations Map 3515 (Valentine and Cross, 2024), which presents maps of seabed topography, ruggedness, backscatter intensity, distribution of geologic substrates, sediment mobility, distribution of fine- and coarse-grained sand, and substrate mud content. The maps of quadrangle 5 show the distribution of substrates across the southern part of Stellwagen Bank and the adjacent basins. Bathymetric and seabed backscatter imagery, photographs, video, and grain-size analyses were used to create the geologic interpretations presented here and have been reprocessed and released in segments to supports these interpretations. For the quadrangle 5 interpretations, data from 729 stations were analyzed, including 620 sediment samples. The seabed geology map of quadrangle 5 shows the distribution of 20 substrate types ranging from boulder ridges to mobile and rippled sand, to mud. Substrate types are defined or inferred through sediment grain-size composition, surface morphology, sediment layering, the mobility or immobility of substrate surfaces, and water depth range. Scientific Investigations Map 3515 portrays the major geological elements (substrates, topographic features, processes) of environments within quadrangle 5. It is intended to be a basis for the study of sediment transport processes that affect a shallow, offshore bank, for the study of the ecological requirements of invertebrate and vertebrate species that use these substrates, and to support seabed management in the region. Purpose: This shapefile contains quadrangle 5 station locations, interpreted geologic substrate at each location, and description of sampling type (sediment sample, video, photograph). Station locations that have sediment samples include the sediment analyses data. These stations represent information used in the geologic interpretation. Supplemental_Information: Over 50 scientific cruises have been conducted in an in an effort to map Stellwagen Bank. For this interpretation of Quadrangle 5 on Stellwagen Bank, ground-truth stations on the following 23 USGS WHCMSC field activities have played a vital role: 1993-006-FA, 1993-023-FA, 1993-030-FA, 1994-004-FA, 1994-014-FA, 1995-012-FA, 1995-015-FA, 1995-036-FA, 1996-025-FA, 1996-037-FA, 1996-038-FA, 1998-017-FA, 1998-022-FA, 1998-029-FA, 1999-011-FA, 2013-044-FA, 2014-015-FA, 2014-055-FA, 2014-066-FA, 2015-017-FA, 2015-062-FA, 2016-038-FA, 2019-008-FA.

Online_Linkage: https://doi.org/10.3133/sim3515 Data_Quality_Information: Logical_Consistency_Report: All of the sediment samples were processed at the Woods Hole Coastal and Marine Science Center sediment lab. In most cases, the presence or absense of ripples was based on the video. If no video files are available, ripples was set to 9999. However, there are instances where no video is available, but the log book indicates the presence of ripples based on real time video observations (but no video files recorded). Completeness_Report: All stations used to derive the geologic substrate interpretation of quadrangle 5 are included in this dataset. Many of the project sites were sampled repetitively over this time period and not all data collected was required to compile the geologic substrate interpretation. The last cruise that provided sediment texture and video data was conducted in November, 2015 (2015-062-FA). Two stations visited at a later date (4554 and 4929) provided data for identifying substrate W which is unmappable as a separate polygon unit. There are 3 stations that indicate no video, photographs, or sediment sample were acquired. However, the comments attribute explains why these stations are included. Instances occurred where the grab sampler could not obtain a viable sample for complete sediment analysis, but the presence of cobble(s) in the sampler did give insight as to the geologic substrate. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were navigated with a differential global position system (DGPS) that varied depending on year of collection. These DGPS locations are assumed to be accurate to +/- 10 meters horizontally. During deployment, the camera system hangs below the side of the ship, and the recorded navigation data closely approximates the position of the camera system near the seabed. The ship is oriented so that wind and waves will not cause it to drift over the conducting cable attached to the SEABed Observation and Sampling System (SEABOSS). Considering navigation system accuracy, cable out, location of navigation antenna relative to camera system deployment - these locations are assumed to be accurate +/- 30 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Depth values were acquired by two methods. Depth was acquired using the ship fathometer until 1998. From 1998 and 1999, depth was acquired using the depth sensor on the SEABOSS. Starting again in 2013, depth values were acquires using the ship fathometer. Depth values were rounded to the nearest meter to account for ship motion. No adjustment was made for tides or transducer depth in the case of using the ship fathometer. Depths are assumed to be accurate to within 5 meters, generally assumed to be accurate to +/- 2 meters.

The observations from video and still cameras and the sediment data are used to explore the nature of the seafloor and, in conjunction with high-resolution geophysical data, to make interpretive maps of sedimentary environments and validate the acoustic remote sensing data. The SEABOSS is a simple system that can be deployed from both small and large surface vessels and operates in water depths up to 200 m. Although the configuration has been modified over the years, it typically incorporates two video cameras, a still camera, a depth sensor, and a modified Van Veen sediment sampler. The elements of the SEABOSS system used on Stellwagen Bank are housed within a stainless-steel framework that measures 1.2 x 1.2 meters and weighs approximately 136 kilograms overall. The frame has a stabilizer fin that orients the system as it drifts over the seabed. The height of the camera above the seabed (76 cm; 30 in) initially was determined by viewing an object hanging from the SEABOSS below the video camera; when the object touched the seabed, the camera height was appropriate for still photography. Later in the project, the camera height was determined by viewing a pattern of laser beams on the seabed. Two parallel lasers are set 20 cm apart on the SEABOSS frame and project onto the seabed for scale measurements. All of the system's elements that require power are powered from the surface vessel through a conducting cable. Video displays typically include station number, water depth (from the depth sensor), and date, time, and geographic position (provided by a shipboard navigation system). More recent cruises (the AUK cruises included in this dataset, 2015 and later) collected video images using a battery-operated, high-definition (1920 x 1080 pixels) GoPro digital video camera. During deployment, the camera system hangs directly below the side of the ship, and the recorded navigation data closely approximates the position of the camera system near the seabed. The ship is oriented so that wind and waves will not cause it to drift over the conducting cable attached to the SEABOSS. The winch operator uses a video feed from the system to maintain the camera at the proper height above the seabed and to avoid obstacles. The scientist uses the video to decide when to take a grab sample of seabed sediment. Process_Step: Process_Description: A subset of the published sediment sample analyses of Stellwagen Bank National Marine Sanctuary was separated based on station locations falling within quadrangle 5. Additionally, stations where either video or bottom photographs that fell within quadrangle 5 were also extracted from previously published datasets. These datasets were combined into a single Microsoft Office Excel 2010 spreadsheet. Additional columns of information were added to reflect whether the location marks a sediment sample location, a station that collected video, or a station that collected bottom photographs. Columns were also added to reflect the interpreted geologic substrate at the station location. Typically, the SEABOSS system would be deployed to the sea floor and the ship would drift while video and photos were recorded. When sediment samples were collected, they were acquired at the end of the drift. Sediment sample locations are given as the position of the actual sediment sample. For stations where just video and/or photographs were acquired, the location marks the end of the station drift. Original work startedin 2016, but was completed in 2022, with the final work on the spreadsheet occurring in Microsoft Office 365 Excel software.

The topographically irregular margin of the western edge of A1 suggests that the substrate is a sheet of sand that was transported eastward across the bank crest and down the western flank of the bank. Depth range of A1 is 24 to 55 m. Mean weight percents per grain-size category: mud, <1; sand, 94 (fgS, 3; cgS, 90); gravel, 6 (G1, 5; G2, 1). Substrate A1 is dominantly coarse-grained sand and is very low in mud and fine-grained sand content. The surface is covered with storm-generated sand ripples with wavelengths of 0.5 to 1.0 m, and orientation of ripple crests varies from N-S to NW-SE.

Substrate A3 is a mobile, coarse-grained sand deposit that lies on the crest and upper western flank of Stellwagen Bank. Depth range is 23 to 53 m. Mean weight percents per grain-size category: mud, <1; sand, 98 (fgS, 22; cgS, 76); gravel, 2 (G1, 1; G2 <1). Substrate A3 resembles substrate A1 in being a coarse-grained sand and having a very low mud content. It differs from A1 in having much more fine-grained sand, mostly as 3 phi sand (22 weight percent), and its surface ripples are smaller, with wavelengths of 10 to 20 cm.

Substrate H is a mobile, fine-grained sand deposit that lies on the lower western flank of Stellwagen Bank in the southern part of quadrangle 5. Depth range is 38 to 52 m. Mean weight percents per grain-size category: mud, 2; sand, 98 (fgS, 83; cgS, 15); gravel, <1 (G1, <1; G2, 0). The surface of substrate H is characterized by low, long-wavelength (approximately 40 to 50 m) ripples that are visible in bathymetric imagery as depicted by 1-m contours; shell deposits are present in ripple troughs. Substrate H has an irregular western edge, which suggests it represents a downslope-moving sand sheet. The substrate is bounded upslope to the east by the sand sheet of substrate A1 (rippled, coarse-grained sand) and downslope to the west by substrates K (rippled, coarse-grained sand) and L (immobile, fine-grained sand). Substrate H resembles substrate L in the ratio of fine- to coarse-grained sand content but contains less mud.

Substrate I is an immobile, mixed deposit of fine- and coarse-grained sand that forms a hummocky surface on the lower western flank of Stellwagen Bank. Depth range is 44 to 71 m. Mean weight percents per grain-size category: mud, 7; sand, 92 (fgS, 41; cgS, 51); gravel, 1 (G1, 1; G2, 1). It is bounded to the east in shallower water by substrate A1 (rippled, coarse-grained sand), to the south by substrates H (rippled, fine-grained sand), and L (immobile, muddy, fine-grained sand), to the west by substrate R (fine-grained sandy mud), and to the north by substrate L. Substrate I is similar in grain-size content to the upper layer of substrate J, which it surrounds. The almost equivalent weight percents of fine- and coarse-grained sand, and its relatively high content of 3 phi sand, suggest that substrate I is a thin layer of fine-grained sand (not unlike substrates H and L) overlying an older, coarse-grained sand sheet similar to adjacent substrate A1.

Substrate J is a layered substrate of mobile sand overlying immobile gravel in a depression surrounded by substrate I on the lower flank of Stellwagen Bank. Depth range is 48 to 55 m. Mean weight percents per grain-size category of the coarse-and fine-grained sand upper layer: mud, 4; sand, 93 (fgS, 52; cgS, 40); gravel, 4 (G1, 2; G2, 2).

Substrate K is a mobile sand deposit on the lower flank of Stellwagen Bank east of the eastern end of Southwestern Spur. Depth range is 42 to 50 m. Mean weight percents per grain-size category: mud, 1; sand, 98; (fgS, 24; cgS, 75); gravel, <1 (G1, <1; G2, 0). Substrate K is dominantly coarse-grained sand and is low in mud and fine-grained sand (3 phi sand is more abundant than 4 phi sand). It is bounded by immobile, fine-grained sand in deeper water (substrate L) and by rippled, fine-grained sand in shallower water (substrate H). Topographic imagery suggests that substrate H is a sand sheet that has moved downslope and encroached upon substrate K from the northeast. Substrate K is texturally equivalent to substrate A3. The fact that substrate K (coarse-grained sand) lies at deeper depths than the adjacent substrate H (fine-grained sand) indicates that it was not deposited by present-day sedimentary transport processes.

Substrate L is immobile fine-grained sand that is present in three areas on the lowermost western flank of Stellwagen Bank and on the eastern part of Western Spur. It lies in a region where mud content increases as water depth increases from bank to basin. Depth range is 50 to 77 m. Mean weight percents per grain-size category: mud, 10; sand, 89 (fgS 73; cgS, 17); gravel, 1 (G1, 1; G2, 0). The distribution of substrate L along the lower part of the bank is interrupted in the south by east-west trending substrate Q of Southwestern Spur and farther north by substrate I.

Substrate M is a layered substrate that forms the hummocky surface of the western part of Western Spur, a westward extension of Stellwagen Bank into Stellwagen Basin. Depth range is 59 to 68 m. Mean weight percents per grain-size category of the muddy, coarse-grained sand upper layer: mud, 22; sand, 73 (fgS, 13; cgS, 60); gravel, 5 (G1, 4; G2, 1). The upper layer of substrate M is dominantly coarse-grained sand with less fine-grained sand (3 phi sand is greater than 4 phi sand) and mud. The irregular surface of the substrate indicates the presence of partially-buried gravel features that are visible in bathymetric imagery as depicted by 1-m contours. In some aspects, substrate M resembles the upper layer of substrate Q, which forms the hummocky surface of Southwestern Spur to the south. The upper layer of substrate Q has a similar mud content and lies at similar water depths, but unlike substrate M, it is a muddy, fine-grained sand. Substrate M is bounded in shallower water to the east by substrate L, a muddy, fine-grained sand, and elsewhere by substrate T, a mixed substrate of mud, sand, and gravel that lies in deeper water on the flank of Western Spur.

Substrate Q is a layered substrate that forms the hummocky surface of Southwestern Spur, an elongate feature that extends northwestward into Stellwagen Basin from the lower southwestern flank of Stellwagen Bank. Depth range is 54 to 73 m. Mean weight percents per grain-size category of the muddy, fine-grained sand upper layer: mud, 24; sand, 69 (fgS, 42; cgS, 26); gravel, 7 (G1, 4; G2, 3). The deeper parts of substrate Q are bounded to the north and south by mud substrates S and R, while the shallower parts to the east are bounded by muddy, fine-grained sand substrates L and P. The upper layer of substrate Q is dominantly fine-grained sand (3 phi sand is greater than 4 phi sand) with equal amounts of mud and coarse-grained sand. It resembles the upper layer of substrate M in some aspects (see above), but it is more similar to substrate P which occurs adjacent to Southwestern Spur.

Mean weight percents per grain-size category: mud, 60; sand, 40 (fgS, 37; cgS, 3); gravel, <1 (G1, <1; G2, 0). Substrate R is equivalent to the upper layer of substrate V. Substrate R is bounded on the east by the muddy, fine-grained sands of substrates that lie in shallower water on the lower western flank of Stellwagen Bank and on the flanks of Southwestern Spur and Western Spur. It is bounded on the west by substrate S in Stellwagen Basin, a mud with a fine-grained sand content of only 5 weight percent, mostly in the 4-phi category. Substrate R is characterized by the presence of fish and crab burrows.

Substrate S is bounded along the basin margin by substrate R (fine-grained sandy mud), which lies between S and the fine-grained sands of the lower Stellwagen Bank. Elsewhere, substrate S is bounded by muddy, fine-grained sand (upper layer of substrate Q) on Southwestern Spur, and by muddy, coarse-grained sand (upper layer of substrate T) on the flanks of Fifteen Bank and Western Spur. Substrate S is characterized by the presence of fish and crab burrows.

Substrate U is an immobile, gravel pavement. Video imagery revealed it to be closely-packed pebbles and cobbles with little to no sand veneer. Station 1644 (62 m) is located on the Western Edge of the bank. Weight percents per grain-size category of sediment collected from this station: mud, 10; sand, 44 (fgS, 11; cgS, 33); gravel, 46 (G1, 10; G2, 36).

Substrate V was observed in two areas in Stellwagen Basin that lie in the area occupied by substrate R. Substrate V is a layered substrate that partially covers cobbles and boulders. The upper layer of substrate V is texturally equivalent to substrate R. For mean weight percents per grain-size category of this upper layer, see substrate R. The underlying cobbles and boulders represent almost-buried mounds of gravel that produce a hummocky surface that is visible in bathymetric imagery as depicted by 1-m contours. The gravel features are partly exposed by the scouring and burrowing activities of fish.

Substrate W is a layered substrate of rippled, coarse-grained sand that partially covers outcrops of semiconsolidated mud that occurs in the area occupied by substrate A1. It was observed at 3 locations on the bank crest in quadrangle 5. Water depth range of the stations is 31 to 35 m. Grain-size analyses of all samples identified as W were used to calculate the mean weight percents of aggregates and composite grades of the sediment partial veneer overlying semiconsolidated mud: mud, <1; sand, 88 (fgS, 10; cgS, 78); gravel, 12 (G1, 11; G2, 1). Visual analysis of video imagery revealed the lower substrate to be an irregular, burrowed and fragment-strewn surface. It is interpreted to represent an outcrop of semiconsolidated mud that has been burrowed by benthic organisms. The rippled, coarse-grained sand partial upper layer was collected without disturbing the lower clay layer and is texturally very similar to substrates A1 and A3. Stations identified as deposits of substrate W in the area occupied by substrate A1 are not mappable as a coherent unit at the present scale.

Overview_Description: Entity_and_Attribute_Overview: In the substrate attribute, weight percents described in the domain value definitions may not add to 100 due to rounding of values. Also in the geo_substr attributes, the mean weight percents for the units, sand is divided into two composite grades: fine-grained sand (fgS; 0.062 to <0.25 mm) and coarse-grained sand (cgS; 0.25 to <2mm). Gravel is also divided into two composite grades: Gravel1 (G1; 2 to <8 mm) and Gravel2(G2; 8 to <64 mm). > In the CSV file, the column headings are not truncated. The truncation is a function of converting to a shapefile with a 10-character attribute header limit. In addition to the shapefile and CSV file, there is an accompanying Excel spreadsheet (q5_stations_geology.xlsx). Additional information regarding abbreviations is in the first row of the spreadsheet. > That following information is the second row of the spreadsheet, the more robust header information.
