Abstract

In fall 2001, researchers from the Wells National Estuarine Research Reserve, Virginia Institute of Marine Science, and the NOAA Office for Coastal Management conducted a project to map benthic habitats in the York and Webhannet rivers in southern Maine. The team completed two weeks of fieldwork in September 2001, collecting sediment profile images at 382 stations and sediment grab samples at 93 stations. This data set represents the information gathered from sediment profile imagery sampling.

Purpose:

The Wells Reserve is using the 2001 grab and SPI information to characterize benthic habitats within the York and Webhannet rivers, and to examine relationships between animal communities and sediment characteristics as well as the potential effects of dredging activities. Sediment profile images (SPI) of the sediment-water interface were collected using a sediment profile camera at pre-determined locations in both rivers. Physical, chemical, geological, and biological conditions observed in the photos were used to create a database for all stations, and habitat classes were defined by sediment type and/or faunal community for each location. The database was then used in a Geographic Information System (GIS) to characterize fine scale benthic habitat distributions in the rivers.

Data Quality

Accuracy:

The attribute accuracy was verified by checking the compiled SPI database against the actual photos for each station. Since two photos were taken at each station, attributes from both images were noted in the database, and one image was digitized and analyzed using image analysis software. The results of this automated analysis were also used to check the accuracy of the dataset. When large disagreement occurred between images from a single station, all attributes were recorded and the image with the largest visible area was digitized. Results of grab sampling were also used, when available, to check the accuracy of the SPI data set. Additionally, a subset of the images were evaluated by two other professional benthic ecologists with experience working with SPI. Differences between the original analysis and the QA/QC analysis were addressed in the final data set.

Horizontal Positional Accuracy:

Stations were located in the field using a differential Global Positioning System (GPS), and station coordinates, date and time of day were recorded upon arrival at each station.

Vertical Positional Accuracy:

Not relevant to the data set.

Completeness Report:

All SPI data were not included in this data layer. All stations are represented, however, some parameters, which were harder or more subjective to interpret, were not included in the data set. These data can be found in the project database at the Wells Reserve.

Conceptual Consistency:

All data are believed to be logically consistent.

Process Steps

Process Step 1

CC ID: 612166
Description:

Field Methods: SPI images were collected from 4 to 10 September at a total of 382 stations. A Hulcher model sediment profile camera was deployed with a modified frame that was lightened for use from a small vessel. Fujichrome 100 ASA professional color slide film was used. Tests were done frequently onboard in order to ensure camera function and mark stations. Laboratory Methods: All sediment images were analyzed visually by projecting the images and recording all features seen into a preformatted standardized spreadsheet file. Images were then digitized using a Nikon LS2000 scanner and analyzed using the Adobe PhotoShop and NTIS Image programs. Steps in the computer analysis of each image were standardized and followed the basic procedures in Viles and Diaz (1991). Data from each image were sequentially saved to a spread sheet file for later analysis. Details of how these data were obtained can be found in Diaz and Schaffner (1988) and Rhoads and Germano (1986). References: 1) Viles, C. and R.J. Diaz. 1991.

Process Step 2

CC ID: 612167
Description:

Data from field samples was entered into an Access database for the Wells, Maine benthic SPI survey. A query was developed to review sediment data from all grab sampling stations. See Entity and Attribute section for more information on data collected. A shapefile was created using the field data in the Access database to show spatial trends in benthic community distribution in the two rivers.
