Title: Shallow-water Benthic Habitats in Jobos Bay
Abstract:
Shallow-water (<30m) benthic habitat maps of the nearshore marine environment of Jobos Bay, Puerto Rico were mapped and characterized using visual interpretation of optical and acoustic remotely sensed imagery. The objective of this effort, conducted by NOAA's Center for Coastal Monitoring and Assessment Biogeography Branch in partnership with NOAA's National Estuarine Research Reserve System (NERRS), was to provide spatially-explicit information on the habitat types, biological cover and live coral cover of Jobos Bay's coral reef ecosystem.

Why was the data set created?

This product provides a fine-scale assessment of the status, abundance, and distribution of marine habitats of Jobos Bay, Puerto Rico. The NOAA effort provides the National Estuarine Research Reserve System with increased technical capacity for ocean exploration, management, and stewardship. Direct implications to management measures include evaluation of management efficacy, a spatial framework for improved monitoring sampling design, improved assessment of human-use impacts, and marine spatial planning to support alternative marine protected area boundary alternatives.

    This section of the report describes the habitat classification scheme used to classifiy habitat features. The Jobos Bay habitat classification scheme defines benthic communities on the basis of five primary coral reef ecosystem attributes: 1) broad geographic zone, 2) geomorphological structure type, 3) dominant biological cover, 4) degree of live coral cover, and 5) percent hardbottom.

  2. How were the data generated, processed, and modified?

    Date: 2008 (process 1 of 5)
    1) Imagery Acquisition - The first step in map creation was the acquisition and processing of a comprehensive dataset of remotely sensed imagery. All imagery was geo-positioned to ensure acceptable spatial accuracy in the mapping product. In the case of Jobos Bay, two separate data types were used (color orthophotography and IKONOS satellite imagery) in order to capture the full mappable extent using optical techniques.

    Date: 2009 (process 2 of 5)
    2) Habitat Boundary Delineation - A first draft benthic habitat map was generated by delineating all features that could be identified by visual inspection of the remotely sensed imagery. During the creation of this first draft, the interpreter placed discrete points on the map that were difficult to distinguish and that warranted further field investigation. These sites were labeled as "ground validation" positions.

    Date: 2009 (process 3 of 5)
    3) Ground Validation - NOAA field scientists explored the ground validation locations with a suite of assessment techniques depending on the conditions at each site. A combination of underwater video, free diving, snorkeling and surface observations were used to survey the ecological characteristics at each location. This information was analyzed and the initial maps were edited to generate a second draft map.

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    No comprehensive assessment was conducted to evaluate the thematic accuracy of the Jobos Bay, Puerto Rico benthic habitat map. Consequently, all users should independently analyze the dataset according to their own needs and standards to determine data usability.

  2. How accurate are the geographic locations?

    The accuracy value for the optical imagery was determined by measuring photo-identifiable control points collected with GPS survey methods. There is no horizontal accuracy report for the acoustic imagery. It is believed that polygon horizontal accuracies are inherited from both types of source imagery.

  3. How accurate are the heights or depths?

    None.

  4. Where are the gaps in the data? What is missing?

    Delineation of all habitat boundaries was conducted with the image scale at 1:2,000. This ensured that the level of detail produced by the photo interpreter was uniform throughout the project. The minimum mapping unit (MMU) for identifying habitats or features was 1,000 square meters. The software utilized in this project was designed to alert the photo interpreter each time a polygon was drawn smaller than the a MMU; at which point the polygon was then aggregated with the most logical adjacent polygon.

  5. How consistent are the relationships among the observations, including topology?

    GIS topologic quality was established by executing ArcGIS extension routines that check for: overlapping polygons, multipart polygons, sliver polygons and void polygons. Additionally checks for adjacent polygons with the same habitat attributes were completed. All errors were identified and corrected. This file is believed to be logically consistent.
