Processing spatial data for predictive mapping of benthic substrate and biota: Point Addis Marine National Park. (156 KB PDF)
The following is an overview of methods and data development for mapping: (1) Data processing:
a. Developed secondary datasets from bathymetry; b. Designed and executed video interpretation plan to use as primary field collected data identifying the substrate and biological features on the seafloor; (2) Modelling: Modelled all substrate and biological categories as a function of bathymetry and derived datasets to provide a framework for predicting values in unsampled locations; (3) Mapping: Applied the models to the rest of the Park to predict the most likely substrate and biological features present where no field data was available.


Assessment of error in habitat mapping and how it affects map interpretation.
(142 KB PDF)
For habitat maps, there are two types of errors that may be assessed: spatial and attribute error.


Spatial sampling: Capturing fish distribution and habitat usage data at multiple scales (1 MB PDF).
This segment describes a method for improving sampling of fish distributions and habitat usage. This segment describes a plan for secondary sampling, based on:
1. Analysis of data from a preliminary field sampling dataset
2. The capture of sites across a range of depths and habitats
3. The concentration of sites to test for spatial dependence in fish distributions.

Evaluation of methods and designs to link biodiversity to broad scale habitat assessments (100 KB PDF).
In a condensed form (Table 1), this document summarises i) current ecological theories which are thought to drive patterns of biodiversity at different spatial scales, ii) the common statistical methods that have been applied to these theories, and iii) whether each theory has been applied in a practical sense as a biodiversity surrogate.

Information about the images: All images are from underwater digital still cameras operated from a surface vessel in the Point Addis Marine National Park. The images are Copyright Parks Victoria/Coastal CRC. All images marked "Deep Sponge" were from approximately 50-55m deep and approximately 4 to 5 km from the coast. Any image with "Sponges", "SpongeCity" & "LargeFanClose" in the title are all from 40 - 45m deep and approximately 3.5 km from the coast. The images of "Rhodoliths" were taken at around 33m deep about 2km off shore. The image "LongwaveSand" is from almost 50m depth and is about 4 km offshore.

Click on the image to see a canned demonstration of how the Arc GIS information that can be made available through the web using Arc IMS. The right hand half of the image shows a section of seabed imagery with a black line indicating where towed video was obtained. The bottom left window displays the underwater video of the seabed at the point indicated by the blue marker dot shown on the video track, the black line in the right hand window. The imagery is of Point Addis , shown in the next right hand image.
