Appendix IV: ArcView Project

Viewing the photographs and movies using ArcView

The bottom photos and movies may be viewed in an ESRI (Environmental Systems Research Institute, URL: http://www.esri.com) ArcView 3.2 (or higher) project. In the ArcView project, the station locations can be viewed along with shaded relief or backscatter intensity images of part of the New York Bight (obtained from a multibeam sea floor mapping system (Butman and others (1998) and Butman and others (2002)), backscatter intensity from sidescan sonar (Schwab and others, 2003), or with geologic units identified from the sidescan sonar. These images provide some regional geologic context for the bottom photographs and samples. The multibeam images are preliminary (see metadata for description).

To use the ArcView project, open the file nyofr01_470.apr (located in the nybgis directory) with ArcView 3.2 or higher. A dialogue box will appear requesting the path to the 'nybgis/nypages' directory. If you are running the project from the DVDROM, enter the drive letter of your DVDROM reader (set as D in the pop-up), then click OK. If the project has been copied onto a hard drive, enter the entire pathway to the 'nybgis/nyimage' directory. The ArcView Spatial Analyst extension must be installed to view the NOAA Coastal Relief Model bathymetry theme (remosaic). The MrSID Image support extension must be loaded to view the sidescan sonar theme (Apex_li.sid) that has been compressed with LizardTech (URL: http://www.lizardtech.com/) MrSID Geospatial Encoder 1.3.1 image compression utility.

The ArcView project contains five views. View 1 includes all of the station data in this report. Views 2-4 contain the station information for the sampling locations that were occupied on each cruise. In each view, themes (1) show a station location that provides a link to all photographs (themes ny_stat.shp, seaxstat.shp, alphstat.shp, ocnsstat.shp, or endvstat.shp), (2) show the locations of each still photograph (themes ny_pics.shp, seaxpics.shp, alphpics.shp, ocnspics.shp, or endvpics.shp), (3) show the locations of the grab samples (themes ny_seds.shp, seaxseds.shp, alphseds.shp, ocnsseds.shp, or endvseds.shp), (4) show positions every 10 seconds along the video transects (themes ny_vid.shp, seaxvid.shp, alphvid.shp, ocnsvid.shp, or endvvid.shp), and (5) show the start of the large and small video clips ( movs*.shp for the small format movies, and movl*.shp for large-format movies, where * is the ship abbreviation alph, endv, ocns, or seax). The Key to ArcView Coverage Icons figure (right) illustrates the various themes (colors may vary between views). The individual photo locations (ny_pics.shp, seaxpics.shp, alphpics.shp, ocnspics.shp, or endvpics.shp) are not hot-linked, but the images displayed on the station page are in sequential order from the beginning to the end of the transect. Data sources for the ArcView project file are listed in Appendix V.

To view the photographs at a particular station using a hotlink, click on the photos or movies theme to make it active ( *stat.shp for photos, movs*.shp for the small format movies, and movl*.shp for large-format movies, where * is the ship abbreviation alph, endv, ocns, or seax), click on the lightening bolt icon on the toolbar, then click on the desired yellow station marker with the lightening bolt (the bottom tip of the lightening bolt icon must be positioned over the station marker). If a dialogue box pops up with "Hotlink to web/movie failed, check path", click on the P button in the toolbar, check the path to the folder 'nyimage' and change if necessary. If no movie or image pops up there are no images for that station. Double click on an image in the resulting station page to view a larger image.

Apex_li.sid      Download: sonar.zip
Description: Backscatter intensity from sidescan sonar. Backscatter intensity, the intensity of the acoustic return to the sidescan sonar from the sea floor, is a measure of the properties of the surficial sediments and the bottom roughness. Generally, a strong return (light gray tones) is associated with rock or coarse-grained sediment, and a weak return (dark gray tones) with fine-grained sediments. However, the micro-topography, such as ripples, burrows, and benthic populations also affect the reflectivity of the sea floor. In addition, because the sidescan sonar is towed near the bottom, features on the sea floor may produce shadows (areas of no backscatter return that are shielded from the sonar source because they are located behind objects that protrude above the sea floor or in depressions) in the sonar record. See Schwab and others (2000, 2003) for interpretations of these data. Direct observations, using bottom photography or video, and surface samples, are needed to help verify interpretations of the backscatter intensity data. The sidescan sonar theme (Apex_li.sid) has been compressed with LizardTech (www.lizardtech.com) MrSID Geospatial Encoder 1.3.1 image compression utility.

Description: Backscatter intensity of the Historic Area Remediation Site (HARS) in 1996 as determined by a multibeam survey (Butman and others, 2002).  Backscatter intensity, the intensity of the acoustic return from the sea floor from the multibeam system, is a measure of the properties of the surficial sediments and of the bottom roughness.  Generally, a strong return (light gray tones) is associated with rock or coarse-grained sediment, and a weak return (dark gray tones) with fine-grained sediments.  However, the micro-topography, such as ripples, burrows, and benthic populations also affect the reflectivity of the sea floor.  Direct observations, using bottom photography or video, and surface samples, are needed to verify interpretations of the backscatter intensity data.  The backscatter data have a weak striping that runs parallel to the ship’s track.  Some of the striping is the result of poor data return at nadir that appears as evenly-spaced thin speckled lines. Some striping is also due to critical angle effects, where the intensity of return varies as a function of the angle of incidence of the incoming sound on the seafloor (Hughes-Clark and others, 1997).

Description: Backscatter intensity combined with the topography of the Historic Area Remediation Site (HARS) in 1996 as determined by a multibeam survey (Butman and others, 2002).  In the image shown here, the backscatter intensity is represented by a suite of eight colors ranging from blue, which represents low intensity, to red, which represents high intensity. These data are draped over a shaded relief image created by vertically exaggerating the topography four times and then artificially illuminating the relief by a light source positioned 45 degrees above the horizon from an azimuth of 350 degrees.  The resulting image displays light and dark intensities within each color band that result from a feature's position with respect to the light source.  For example, north-facing slopes, receiving strong illumination, show as a light intensity within a color band, whereas south-facing slopes, being in shadow, show as a dark intensity within a color band.

Unnatural-looking features or patterns oriented parallel or perpendicular to survey tracklines (tracklines run north-south) are artifacts of data collection and environmental conditions.
