The photographs can be accessed online using three methods described below in sections A, B, and C.
A. Access images for each station in a quadrangle via an interactive topographic map in PDF format. Click here to expand/collapse.
Go to the quadrangle webpage of choice.
Open the interactive PDF topographic map with links to photographs in that quadrangle. Adobe Reader is needed to open the map.
The station symbols and numbers are color coded.
Red stations indicate that photographs exist at the site.
Yellow stations indicate that no photographs were taken at the site.
Move the Select tool or Hand tool over the station number to view a tooltip that displays: station number; water depth, m; year photo or sediment collected; grain size analysis if present (mud%, sand%, gravel%); photos or no photos.
Examples:
STA 3084, 45 m, YR 1998, MUD <1%, SND 99%, GVL <1%, Photos
STA 3119, 50 m, YR 1998, MUD <1%, SND 96%, GVL 4%, No Photos
STA 3071, 54 m, YR 1998, No Sediment Analysis, Photos
To find a particular station on the map, zoom to a small area anywhere on the image; enter a station number in the Search box; and the station will be highlighted in the new field of view.
Click on a red station number with the Select tool or Hand tool to open a webpage that displays all photographs for that station in thumbnail format. Images are ordered by file name.

Image files are displayed in three formats.
Level 1: a page showing all thumbnail images (110 x 110 pixels) for a station or a quadrangle that is accessed using methods A, B, or C above. Click here to view an example of a Level 1 page.
Thumbnails can be viewed as a slideshow with a 4 second delay.
The Sort box in the upper right part of the page can be used to arrange the images as follows: Sort by Filename: sorts alphabetically by Field Activity No., then by ascending station no, then by ascending image number. Sort by Date Taken: sorts by date and time image was collected. Sort by Date Submitted and Sort by Caption are not applicable to these images.
To view all Level 1 (thumbnail) images for a particular station, enter the quadrangle no. and the station no. into the Search box in the upper right part of the page in the following format: q6_3084
To view all Level 1 (thumbnail) images for any quadrangle, go to the path displayed on the Level 1 image page and click on the name Stellwagen. Then, click on the thumbnail image representing the quadrangle of choice to view all images for the quadrangle in thumbnail format.
Level 2: a page showing a thumbnail image (520 x 353 pixels) for viewing, with metadata displayed on the page. Click here to view an example of a Level 2 page.
To open a Level 2 image, click on a thumbnail image at Level 1.
