47884 fl_ab99_spi-meta Data Set Published / External 37225 Benthic Project Completed 2004-06-30 The Apalachicola Bay National Estuarine Research Reserve and the NOAA Office for Coastal Management worked together to map benthic habitats within Apalachicola Bay, Florida. The bay and the lower portions of four distributaries were surveyed on 11-22 October 1999 using three benthic sampling techniques. This data set represents the information gathered from sediment profile imagery sampling. Images were collected at 436 stations throughout the bay. Original contact information: Contact Org: NOAA Office for Coastal Management Phone: 843-740-1202 Email: coastal.info@noaa.gov Sediment profile images (SPI) of the sediment-water interface were collected using a sediment profile camera at pre-determined locations in the bay. 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 bay. 10041 Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > BENTHIC Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > COASTAL Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > ESTUARY Theme ISO 19115 Topic Category biota Theme ISO 19115 Topic Category environment Spatial Global Change Master Directory (GCMD) Location Keywords CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > FLORIDA Spatial Global Change Master Directory (GCMD) Location Keywords OCEAN > ATLANTIC OCEAN > NORTH ATLANTIC OCEAN > GULF OF AMERICA Theme Environmental Monitoring Theme GIS Theme OCM Benthic Habitat Mapping Theme SPI Theme benthic data Theme geographic information system Theme sediment profile image Spatial Apalachicola Spatial East Bay Spatial Florida Spatial Gulf of Mexico Spatial St. George Sound Spatial St. Vincent Sound Office for Coastal Management Charleston SC Data Set None Planned Map (digital) While every effort has been made to ensure that these data are accurate and reliable within limits of the state of the art, NOAA will not assume any liability for damages caused by any inaccuracies in these data, or failure in their use.

Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 4; ESRI ArcCatalog 8.3.0.800 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. 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. Not relevant to the data set. 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 Apalachicola Bay benthic database, available from the NOAA Office for Coastal Management. All data are believed to be logically consistent.

Diaz and Daughters Range 1999-10-11 1999-10-22 Production and analysis of sediment profile images for habitat characterization and use in a GIS database. | Source Geospatial Form: None | Type of Source Media: 35 mm slide film 1 At 436 stations, a Hulcher sediment profile camera, fitted with a digital video camera to allow for real-time viewing of the sediment profiles, was deployed from one to four times. The profile camera was triggered from the boat while viewing images from the video camera; one to four profile images were taken on each deployment. In the softest sediments, the first image was taken within a second of bottom contact, when the camera had penetrated was 15 to 20 cm into the sediment. Subsequent film images were taken 10 to 30 seconds after the camera had reached the bottom. Film images were taken using Fujichrome 100P slide film. This combination of real-time video and surface triggering of the film camera insured that the sediment-water interface would be photographed before the prism window had passed the sediment-water interface.All sediment profile film images were analyzed visually by projecting the images and recording observed features into a standardized spreadsheet. Details of how these data were obtained can be found in Diaz and Schaffner (1988). All 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). References: 1) Diaz, R.J., and L.C. Schaffner. 1988.
