This past week has been a blast and it was spent doing a plethora of field activities, data processing and extrapolation, and classroom instruction.

Day 2, we learned about geological succession and barrier island formation. Then we went out to Horseshoe Key and took a 2 1/2 m sediment core and visited a Calusa shell mound. Upon return, we promptly cut open the sediment core collected at Horseshoe Key as well as a sediment core taken from the Calusa shell mound by the previous weeks group and examined the different layers determine when the ocean was transgressing and regressing.
Day 3, we learned about the importance of phytoplankton and zooplankton, the differences between the ocean and bay/riverside conditions and their effects on species richness and abundance, and collected samples along a predestinated transect. We then examined the specimens collected and performed some statistical analyses to determine how variables like salinity, temperature, and tidal influence effected the species present.
Day 4, we learned about the seven species of seagrasses native to Florida, although we only observed four, the importance of seagrasses to an estuarine habitat, the fauna which inhabit them at some point during their lives, current monitoring projects. We then visited three different sites along the bay and performed quadrat sampling to determine species richness and abundance of both seagrasses and algae. Then we plotted the data to determine the average depth that seagrasses are found and were able to physically observe areas which show seagrass coverage via remote mapping and determine if there was actual seagrass there.
