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. Bathymetry and sidescan-sonar imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities in Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During October 2008 NOAA completed hydrographic survey H11997 offshore in eastern Long Island Sound, and during May 2010 bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Two interpretive data layers were derived from the multibeam echo-sounder and the ground-truth data used to verify them. For more information on the ground-truth survey see https://cmgds.marine.usgs.gov/fan_info.php?fa=2010-015-FA.
The purpose of this dataset is to release the mid-resolution and full-resolution JPEG images of photographs and frame grabs of video of the sea floor acquired offshore in eastern Long Island Sound, with a mid-sized SEABOSS system during USGS survey 2010-015-FA conducted aboard the OSV Bold during May 24-28, 2010. These photographs can be used to provide information on surface geology, sedimentary processes, and habitats.

Information unavailable from original metadata.
All images of the sea floor collected within the study area offshore in eastern Long Island Sound, on cruise 2010-015-FA with the mid-sized SEABOSS system are included. Total station numbers range from 997-1 to 997-28. Frame grabs of video are supplied with the mid-res dataset; not all of the photos collected on the cruise were collected within the study area.
The mid-sized SEABOSS was designed and built at the USGS Woods Hole Science Center. This system is equipped with two video cameras, a still camera, and a van Veen grab sampler. This system, weighing approximately 185 lbs, can be used to depths up to 40 meters. The multi-conductor electrical cable is manually deployed. The system also has a 50 Watt/second flash unit 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 video 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 mid-sized 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 mid-sized SEABOSS system was deployed to capture still photos and bottom video offshore in eastern Long Island Sound. This system was used to obtain video and 1 to 4 images at each station as the OSV Bold drifted over the seabed for 2 to 5 minutes. The video was collected with a Kongsberg Simrad model OE1365 video camera. The third laser on the system was set to an angle such that the optimum photograph height was 50 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 1/250 second. A total of 70 acceptable still photographs of the sea floor, which were recorded on 35-mm film, were acquired at 25 stations within the study area with a Photosea 1000 stills camera. Although the images themselves have no georeferencing information, the navigation related to each photograph is available in an ESRI formatted shapefile: 2010_015_997botphotos.shp. This data can be downloaded from the following locations: https://pubs.usgs.gov/of/2010/1150/data/botphotos/2010_015_997botphotos.zip; https://pubs.usgs.gov/of/2010/1150/html/catalog.html

Frame grabs of the 8-mm bottom video were taken using SnapzProX to acquire images of the sea floor at three stations where acceptable still photographs of the sea floor had not been collected (stations 997-4, 997-7, and 997-21). Frame grabs have "fg" inserted into their file names (e.g., 997-4a_fgmr.jpg) to differentiate them from the still photographs.

The full-resolution JPEG images (2560x1920 pixels) were downsampled using Photoshop CS to create JPEG images with 600 x 450 pixels. The filenames indicate the resolution. For instance, the full-resolution JPEG image - 997-8a_fr.jpg - was downsampled to produce mid-resolution JPEG image 997-8a_mr.jpg.

Edits to the metadata were made to fix any errors that MP v 2.9.36 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.). Attempted to modify http to https where appropriate. Updated the link to the field activity. Moved the minimal source information provided to make it the first process step. 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.
