Anthropogenic influence from urbanization affects the health of estuaries all over the world. Three urbanized bayous in the Pensacola Bay System (Bayou Texar, Bayou Chico, and Bayou Grande) are estuarine systems affected by their surrounding watersheds. Land use in Bayou Texar's watershed is mainly residential properties. Bayou Chico's lower watershed is mainly industrial, while the upper watershed is residential. In Bayou Grande, one shoreline is home to the Naval Air Station, Pensacola, and...
Show moreAnthropogenic influence from urbanization affects the health of estuaries all over the world. Three urbanized bayous in the Pensacola Bay System (Bayou Texar, Bayou Chico, and Bayou Grande) are estuarine systems affected by their surrounding watersheds. Land use in Bayou Texar's watershed is mainly residential properties. Bayou Chico's lower watershed is mainly industrial, while the upper watershed is residential. In Bayou Grande, one shoreline is home to the Naval Air Station, Pensacola, and the other shoreline is residential. This study examined spatial and temporal variability of water quality in these systems. Comparison of bimonthly samples with historical data provided a perspective of how water quality has changed and responded to urbanization in these systems. High nutrients and chlorophyll were observed in Bayou Chico and Bayou Texar. Seasonal variation in nutrients was smaller than expected. Mixing curves of nutrients showed non-conservative mixing reflecting spatially distributed sources and sinks. DIN to DIP ratios showed that phosphorus was the limiting nutrient in Bayous Chico and Texar, whereas in Bayou Grande there was a seasonal change in nutrient limitation from nitrogen to phosphorus. Warm temperatures, and high light availability, make these urban bayous susceptible to eutrophication.

Booker Fish Camp project is an archaeological study applying a multi-method approach to explore the terrestrial and submerged aspects of a twentieth century fish camp in Escambia County, Florida. It explores the dichotomy of a site that is both residential and commercial, and remote yet part of a community. The duality of this land/water and residential/commercial endeavor is explored through an analysis of a large surface trash midden and viewed through the lenses of maritime cultural...
Show moreBooker Fish Camp project is an archaeological study applying a multi-method approach to explore the terrestrial and submerged aspects of a twentieth century fish camp in Escambia County, Florida. It explores the dichotomy of a site that is both residential and commercial, and remote yet part of a community. The duality of this land/water and residential/commercial endeavor is explored through an analysis of a large surface trash midden and viewed through the lenses of maritime cultural landscape and waterscape archaeology. The analysis provides a fascinating look at the intertwined relationship of land and water, residence and commerce, and home and community.
