Description:
Abstract:
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, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities off southern New England, shows the character and terrain of the seabed, and provides information on sediment transport and benthic habitat. During April-May 2009 NOAA completed hydrographic survey H12007 in the vicinity of Cross Rip Channel in Nantucket Sound off southern Cape Cod, Massachusetts and during June 2011 bottom photographs and surficial sediment data were acquired as part of ground-truth reconnaissance surveys of this area. Interpretations were derived from the multibeam echo-sounder data and the ground-truth data used to verify them.
Purpose:
The purpose of this dataset is to release the mid-resolution and full-resolution JPEG images of bottom photographs acquired in Nantucket Sound with a SEABOSS system during USGS survey 2011-006-FA.

Completeness_Report:
All 90 images of the sea floor collected at 24 stations in Nantucket Sound on USGS RV Rafael cruise 2011-0006-FA with the mini SEABOSS system are included. Test photos taken on deck and photos taken in the upper water column during 'false trips' were deleted from the dataset; photographs taken in Rhode Island Sound and Block Island Sound as part of this cruise are also not included.

The Mini SEABOSS was designed specifically for the USGS Woods Hole Science Center's 26-foot research vessel 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. For more information on the SEABOSS system please see the cross references.

Process_Description:
The USGS Mini SEABOSS system was deployed to capture still photos and bottom imagery in the vicinity of Cross Rip Channel, in Nantucket Sound as part of USGS RV Rafael cruise 2011-006-FA.This system was used to obtain 3 to 6 still photographs at each station as the vessel drifted over the seabed for 2 to 5 minutes. Two lasers were set to provide scale; 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 0.4 to 0.7 meter from left to right. Other camera settings on the Mini SEABOSS 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 90 images of the sea floor were acquired. Although the images themselves have no georeferencing information, the time in the EXIF header of each image is related to the navigation available in an ESRI formatted shapefile: 2011_006_crbotphotos.shp.

The digital images were recorded on a flash card within the camera and transferred from the camera at the end of the day. This transfer was accomplished by removing the card from the camera and using a card reader connected to a Mac OSX system.

Process_Description:
The full-resolution JPEG images (2560x1920 pixels with the Mini SEABOSS) were downsampled using Photoshop CS to create mid-resolution JPEG images with 600 x 450 pixels. As part of this process, brightness levels of some of the mid-resolution images were adjusted to optimize image quality. The filename indicates that the image is the mid-resolution version. For instance, the full-resolution JPEG image - cr1a.jpg - was downsampled to produce cr1a_mr.jpg.
