Abstract:

This data set contains images from Wormcams deployed in directly adjacent marshes in Terrebonne Bay. Wormcam hydrographic and Sediment Profile Image (SPI) analysis are available through GRIIDC Unique Dataset Idenitifers (UDIs) R1.x139.144:0024 and R1.x139.144:0002, respectively.

Purpose:

The intent of this data was to serve as a time-series account of the biological dynamics of the subsurface benthic environment at subtidal sites directly adjacent to marshes in Terrebonne Bay, LA.

Data Parameters and Units:

Image files organized as follows: "Clean", "Oiled" directories Time span subdirectories "YYYYMMDD - YYYYMMDD" Daily subdirectories "***_###_DD_YYYY", where *=the 3 letter abbreviation of the day of the week and ###=3 letter abbreviation of the month. File formats=“WormcamX.*** (where X=wormcam number and *** is the 3 letter abbreviation of the day of the week)_DD_YYYY.HH_MM_SS.trig+0.jpg (default file suffix.jpg)" Site locations: TB1: 29.293060,-90.605000 (Clean site) TB3: 29.304440,-90.565830 (Oiled site) TB4: 29.296390,-90.549720 (Clean site)

Methods:

The cameras were set to take a burst of 8 to 12 images, about 15-seconds apart every half hour.

Error Analysis:

Some partial or blank image files were generated when the camera happened to be sending images remotely while also recording or powered down during image capture. More images were collected than later analyzed (UDI R1.x139.143:0002) because only one usable image was needed for each half hour. The extra images were used as replicates for instances when partial image capture occurred or for the compilation of interactive movies.
