Title:
SEABOSS Images in JPEG Format from Cruises 2010-010-FA and 2010-015-FA in Long Island Sound North of Duck Pond Point, New York
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the Connecticut Department of Environmental Protection and National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities along this part of Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from the multibeam echo-sounder data collected north of Duck Pond Point, New York. During April and May 2010, bottom photographs and surficial sediment data were acquired during 2 cruises as part of USGS ground-truth reconnaissance surveys of this area. For more information on the ground-truth surveys see https://cmgds.marine.usgs.gov/fan_info.php?fa=2010-015-FA.

Why was the data set created?

The purpose of this dataset is to release the thumbnail resolution, mid-resolution, and full-resolution JPEG images of bottom photographs acquired with a small SEABOSS system during USGS survey 2010-010-FA and the mid-sized SEABOSS system during USGS survey 2010-015-FA in Long Island Sound, north of Duck Pond Point, New York.

    Source_Contribution:
    On cruise 2010-010-FA: 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 185 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 Minolta Dimage 7Hi, is mounted in a machined Delrin housing with a flat port and is set for 2560 x 1920 pixel images at the "fine" setting for compression. This allows the camera to be used for over 200 images with a 1 GB Compact Flash card without downloading. 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 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.
    On cruise 2010-015-FA: For cruise 2010-015-FA: The USGS mid-sized SEABOSS system was deployed to capture still photos and bottom video eastern Long Island Sound. This system was used to obtain video and 3 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 26 still photographs of the sea floor, which were recorded on 35-mm film, were acquired at 8 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: h11999_botphotos.shp. This data can be downloaded from the following locations: <https://pubs.usgs.gov/of/2011/1149/data/botphotos/h11999_botphotos.zip>; <https://pubs.usgs.gov/of/2011/1149/html/catalog.html>
  2. How were the data generated, processed, and modified?
    Date: 2010 (process 1 of 8)
    On cruise 2010-010-FA: The USGS Mini SEABOSS system was deployed to capture still photos and video in the vicinity of Duck Pond Point, New York. This system was used to obtain 2 to 9 still photographs at each station as the R/V Rafael drifted over the seabed for 2 to 5 minutes.
    For cruise 2010-015-FA: The USGS mid-sized SEABOSS system was deployed to capture still photos and bottom video eastern Long Island Sound. This system was used to obtain video and 3 to 4 images at each station as the OSV Bold drifted over the seabed for 2 to 5 minutes. Person who carried out this activity:

    Date: 2010 (process 2 of 8)
    For cruise 2010-010-FA: The digital images were recorded on a flash card within the camera. Because this was a fairly short cruise, with few photos, the images were not transferred from the camera until post-cruise, back in the lab. This transfer was accomplished by removing the card from the camera and using a card reader connected to a Mac OSX system.
    For cruise 2010-015-FA: Back ashore, the rolls of 35-mm film taken on the cruise within the study area were commercially developed by boulderprophoto.com and scanned to produce the digital JPEG images. Person who carried out this activity:

    The full-resolution JPEG images (2560 x 1920 pixels for the mini-SEABOSS and 3615 x 2451 for the mid-sized SEABOSS) were downsampled using Photoshop CS to create JPEG images with medium resolution (600 x 450 pixels for the mini-SEABOSS and 600 x 407 for the mid-sized SEABOSS) and thumbnails (150 x 112 pixels for the mini-SEABOSS and 150 x 101 for the mid-sized SEABOSS). The filename indicates the image resolution. For instance, the full-resolution JPEG image, 999-1a_fr.jpg, was downsampled to produce medium-resolution JPEG image, 999-1a_mr.jpg, and thumbnail 999-1a_tn.jpg. Person who carried out this activity:

    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 field activity link. Fixed the link to the browse graphic. The source information was incomplete and had to be modified to meet the standard. Added the online link to the zipped data file in the distribution section. 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. Person who carried out this activity:
