The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetric and sidescan-sonar data, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities along this part of Block Island Sound, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. During June 2012, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Interpretations were derived from the multibeam-echosounder, sidescan-sonar, sedimentary, and photographic data collected in Block Island Sound. For more information on the ground-truth survey see <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2012-002-FA>.
The purpose of this dataset is to release the mid-resolution and full-resolution JPEG images of bottom photographs acquired with a small SEABOSS system during USGS survey 2012-002-FA in the H12023 study area in Block Island Sound.

Information unavailable from original metadata.
All 129 images of the sea floor in the H12023 study area collected on R/V Rafael cruise 2012-002-FA with the mini SEABOSS system are included. The file-naming convention used includes a four-letter abbreviation for the study area (nbis), followed by the station number, the picture letter from that station, and the resolution if it is not full resolution (tn for thumbnail, mr for medium resolution). For instance, nbis1bmr.jpg is an image from northern Block Island Sound study area, station 1, picture b, in medium resolution.

The Mini SEABOSS (SEABed Observation and Sampling System) was designed specifically for the USGS Woods Hole Science Center's 26-foot research boat Rafael. This system is equipped with two video cameras, a digital still camera, and a Van Veen grab sampler. This system, weighing approximately 201 lbs, can be used to depths up to 40 meters. The grab itself is raised and lowered with a 3/16-inch Aramid fiber winch-line with a breaking strength of 5,600 pounds. The davit is secured when the Mini SEABOSS is in the water. The electrical cable is on a spring-wound take-up reel with electrical slip rings that is mounted aft of the sampler. This arrangement protects the 0.38-in. multi-conductor cable and keeps the Mini SEABOSS correctly oriented with the boat. This multi-conductor cable enables communication between the ship's lab and the Mini SEABOSS system. The digital camera, a Canon G12, is mounted in a machined Delrin housing with a flat port and is set for 3648 x 2736 pixel images at the "fine" setting for compression. Photographs are stored in the camera on an SD card. The system also has a 50 Watt/second flash unit (Ikelite Digital Substrobe DS51) powered by 8 AA batteries. Two battery-powered lasers are set 15 cm apart for scale measurements. The red laser dots can usually be seen in the photo depending on the bottom type and the distance to the sea floor. A third battery powered laser is positioned at an angle so that when it intersects the other lasers, the Mini SEABOSS is at the optimum height off the bottom for a still photograph. The camera is set to a manual focus and set to a default focus distance once the camera is powered up. The default focus distance is slightly less than the optimum height above the seafloor to account for optical distortion under water.
The USGS Mini SEABOSS system was deployed to capture still photos and video in the H12023 study area in Block Island Sound. This system was used to obtain 3 to 8 still photographs at each station as the R/V Rafael drifted over the seabed for 2 to 5 minutes. The third laser on the system was set to an angle such that the optimum photograph height was 60 cm. The default focus on the camera was set to 50 cm. The imaged area is most often within .3 to 1 meter from left to right. Other camera settings are as follows: aperture is set at f/8; shutter speed is 1/251 second; standard color mode. The camera time is set to GMT. A total of 129 images of the seafloor were acquired. Although the images themselves have no georeferencing information, the navigation related to each photograph is available in an Esri formatted shapefile: 2012-002_023botphotos.shp. These data can be downloaded from the following locations: http://pubs.usgs.gov/of/2013/1003/data/botphotos/2012-002_023botphotos.zip; http://pubs.usgs.gov/of/2013/1003/html/catalog.html.

The digital images were recorded on an SD memory card within the camera. The images were transferred from the camera to a hard drive at the end of each day in the field. This transfer was accomplished by removing the card from the camera and using a card reader connected to a Windows laptop.

The full-resolution JPEG images (3648 x 2736 pixels) were downsampled using Photoshop CS to create JPEG images with medium resolution (600 x 450 pixels) and thumbnails (150 x 113 pixels). The filename indicates the image resolution. For instance, the full-resolution JPEG image, nbis1a.jpg, was downsampled to produce medium-resolution JPEG image, nbis1amr.jpg, and thumbnail nbis1atn.jpg.

Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The source information was incomplete and had to be modified to meet the standard. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
