Abstract:

Autonomous underwater gliders with customized sensors were deployed in October 2011 on the central West Florida Shelf to measure a Karenia brevis bloom, which was captured in satellite imagery since late September 2011. This dataset contains data used to create figures for publication: Zhao, J., Hu, C., Lenes, J.M., Weisberg, R.H., Lembke, C., English, D., Wolny, J., Zheng, L., Walsh, J.J., and Kirkpatrick, G. 2013.

Purpose:

To evaluate the biological diversity and trophic interactions among organisms ranging from primary producers to apex predators and from the deep-sea benthos to the coast. These data contribute to a food web model used to determine risks to ecosystem structure and function and regional economies following from extreme anthropogenic events (e.g., discharged and background hydrocarbon) and adaptive management strategies.
