Title:
SEABOSS Images from the Cruise 2010-010-FA in Long Island Sound North of Orient Point, New York, in JPEG Format (2010-010_OPBPHOTOGRAPHS)
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 and sidescan-sonar data collected north of Orient Point, New York. During April 2010, bottom photographs and surficial sediment data were acquired as part of a USGS ground-truth reconnaissance survey. For more information on the ground-truth survey see https://cmgds.marine.usgs.gov/fan_info.php?fa=2010-010-FA.

Why was the data set created?

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 2010-010-FA in the vicinity of Orient Point, New York.

    Source_Contribution:
    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.
  2. How were the data generated, processed, and modified?
    Date: 2010 (process 1 of 8)
    The USGS Mini SEABOSS system was deployed to capture still photos and video in the vicinity of Orient Point, New York. This system was used to obtain 3 to 7 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 1/250 second; digital Effects settings are Color +1, Contrast +1, and Filter +1 (Warming). The camera time is set to GMT. A total of 106 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: 2010-010_opbotphotos.shp. This data can be downloaded from the following locations: https://pubs.usgs.gov/of/2010/1100/data/botphotos/2010-010_opbotphotos.zip; https://pubs.usgs.gov/of/2010/1100/html/catalog.html.

    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. Person who carried out this activity:

    The original JPEG images were renamed from the sequential, camera automatic filename to a filename reflecting station location. This was done for each individual file in Windows Explorer. Person who carried out this activity:

    The full-resolution JPEG images (2560 x 1920 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, op1a_fr.jpg, was downsampled to produce medium-resolution JPEG image, op1a_mr.jpg, and thumbnail op1a_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 link to the field activity. 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.
