Southeast Florida Reef Tract Water Quality Assessment

Coral reefs are vibrant, productive ecosystems that face a variety of threats, including disease, temperature stress and pollution. In order to effectively manage coral reef resources, adequate data are required to assess status and track change in these systems. The state of Florida has over 100 linear miles of coral reefs north of Miami that, … Read more

Guidelines for Bathymetric Mapping and Orthoimage Generation using sUAS and SfM, An Approach for Conducting Nearshore Coastal Mapping

The absence of accurate, contemporary, or detailed bathymetric data in nearshore coastal waters impedes coastal research, conservation, disaster response, planning, and management efforts. The use of small Unmanned Aircraft Systems (sUAS) and low cost RGB (red, blue, green) cameras, coupled with advanced photogrammetry methods, structure from motion (SfM), provides a portable, efficient, rapid-response, and cost-effective … Read more

Excess Nutrients in Vatia Bay, American Samoa: Spatiotemporal Variability, Source Identification and Impact on Coral Reef Ecosystems

Water quality problems, including sedimentation and over enrichment of nutrients, have the potential to adversely impact coral reef ecosystems. Phosphorus and reactive nitrogen can enter the environment from chemical fertilizers (residential, commercial and agricultural uses), industrial sources, animal waste, and human waste. Excess nutrient loads can impact coral both directly (e.g. lowered fertilization rates) and … Read more
