The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Massachusetts Office of Coastal Zone Management (MA CZM), 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 the Massachusetts coastline, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from multibeam echo-sounder and sidescan-sonar data collected in the vicinity of Edgartown Harbor, Massachusetts. During August 2008 seismic-reflection profiles were acquired, and during September 2008 bottom photographs and surficial sediment data were acquired as part of two ground-truth reconnaissance surveys.
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 08012 conducted September 8-9, 2008.

Information unavailable from original metadata.
All 161 images of the sea floor collected on RAFA08012 cruise with the mini SEABOSS system are included. Gaps in the file names are not missing bottom photos. These gaps were caused when test photos taken on deck and photos taken in the upper water column during 'false trips' were deleted from the dataset.
The source information was incomplete and had to be modified to meet the standard. Assumed to be USGS.

The Mini SEABOSS 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.
The USGS Mini SEABOSS system was deployed to capture still photos and bottom imagery in the vicinity of Edgartown Harbor, offshore Massachusetts. This system was used to obtain 3 to 6 still photographs at each station as the RV 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 1/350 second; digital Effects settings are Color +1, Contrast +1, and Filter +1 (Warming). The camera time is set to GMT. A total of 161 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: rafa08012_botphotos.shp. This data can be downloaded from the following locations: http://pubs.usgs.gov/of/2009/1001/data/botphotos/rafa08012_botphotos.zip; http://pubs.usgs.gov/of/2009/1001/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. Dann Blackwood also performed this work.

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.

The full-resolution JPEG images (2560x1920 pixels) were downsampled using Photoshop CS to create JPEG images with 600 x 450 pixels. The filename indicates that the image is the mid-resolution version. For instance, the full-resolution JPEG image - e1a.jpg - was downsampled to produce e1a_mr.jpg. This work was performed by Dann Blackwood.

Edits to the metadata were made to fix any errors that MP v 2.9.30 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.). This file had a source contribution, but no other source information. This information 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.
