Description:
Abstract:
The USGS, in cooperation with NOAA, is producing detailed maps of the seafloor off southern New England. The current phase of this cooperative research program is directed toward analyzing how bathymetric relief relates to the distribution of sedimentary environments and benthic communities. As part of this program, digital terrain models (DTMs) from bathymetry collected as part of NOAA's hydrographic charting activities are converted into ESRI raster grids and imagery, verified with bottom sampling and photography, and used to produce interpretations of seabed geology and hydrodynamic processes. Although each of the 7 continuous-coverage, completed surveys individually provides important benthic environmental information, many applications require a geographically broader perspective. For example, the usefulness of individual surveys is limited for the planning and construction of cross-Sound infrastructure, such as cables and pipelines, or for the testing of regional circulation models. To address this need, we integrated the 7 contiguous multibeam bathymetric DTMs into one dataset that covers much of Block Island Sound. The new dataset is adjusted to mean lower low water, is provided in UTM Zone 19 NAD83 and geographic WGS84 projections, and is gridded to 4-m resolution. This resolution is adequate for seafloor-feature and process interpretation, but small enough to be queried and manipulated with standard GIS programs and to allow for future growth. Natural features visible in the grid include boulder lag deposits of submerged moraines, sand-wave fields, and scour depressions that reflect the strength of the oscillating tidal currents. Bedform asymmetry allows interpretations of net sediment transport. Together the merged data reveal a larger, more continuous perspective of bathymetric topography than previously available, providing a fundamental framework for research and resource management activities off this portion of the Rhode Island coast.Interpretations were derived from the multibeam echo-sounder data and the ground-truth data used to verify them. For more information on the ground-truth surveys see <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2011-006-FA>
Purpose:
The purpose of this dataset is to release the mid-resolution and full-resolution JPEG images of bottom photographs acquired in Block Island Sound with a SEABOSS system during USGS survey 2011-006-FA.

Completeness_Report:
All 406 images of the sea floor collected at 86 stations in Block Island 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 Nantucket 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 Block Island Sound as part of USGS RV Rafael cruise 2011-006-FA.This system was used to obtain 3 to 7 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 406 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_bisbotphotos.shp.

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 - bis1a.jpg - was downsampled to produce bis1a_mr.jpg.
