Advancements in Seafloor Mapping and Habitat Assessment for Ecosystem Management

We are a team of geological oceanographers employing advanced geophysical and geological tools to capture images of the seafloor and its subsurface. Our work involves studying sedimentary processes and geological frameworks, such as karstified Eocene limestone and marsh hammocks. Historically, we faced challenges with navigation and data processing, which limited our mapping capabilities. Today, we use precise navigation and digital techniques to produce high-quality bathymetric and benthic habitat maps, contributing significantly to ecosystem management and fundamental ecological inquiries.

Presentation Transcript

  1. Who are we? • Geological oceanographers • Use geophysical tools to obtain images of seafloor and its subsurface. • Use geological tools to groundtruth these images.

  2. Sedimentary process studies

  3. Geologic framework studies

  4. Karstified Eocene Limestone Surface

  5. Marsh Hammocks

  6. Bedrock Control on Marsh Hammocks

  7. The past… • Widely spaced track lines producing incomplete benthic maps • Poor navigation • Analog, limited digital acquisition and processing • Map products hand constructed on computers • Labor intensive

  8. Bedforms on Suwannee River Bottom

  9. Limestone Outcrop on Suwannee River Bottom

  10. The present, future… • Precise navigation • Digital acquisition and processing • Computer generated maps • Precise bathymetry • Seafloor classification systems • Map benthic habitats

  11. We propose… • Baseline bathymetric, benthic habitat, and seafloor mapping for the lower Suwannee River and the adjacent inner continental shelf. • These tools are essential in ecosystem management; can be used to ask more fundamental questions.
