Approach:
- sampling conducted at various sites in Tampa Bay (Alafia River, Ballast Point, Gandy Bridge, Feather Sound)
- shrimp burrows and surface sediment collected, as well as sediment ejected from the burrows by the shrimp in 24h (generally n=10 per sediment type/site)
- so far, sediment analyzed for organic content, silt/clay content, Zn and Cd levels (Feather Sound samples being analyzed)
