Abstract:
"The objective of this project was to extend our previously funded ARRA and NOAA CRC funded work over a second post-restoration field season (7/12-2/13) including assessments of a) sedimentation, b) water quality (TSS), and c) rainfall. Our study examined sediments in three reservoirs in the bays: suspended sediments (water samples), settling sediments (sediment traps) and accumulated sediments (bay-floor benthic surface samples). Our approach was first to evaluate the relationship between rainfall and terrigenous sediment accumulation over the time series, then to make spatial comparisons of data among sites drained by a) undeveloped (control) watersheds, and b) restored sites and finally to make temporal comparisons among data collected prior to restoration (2008- 11) and after the restoration was complete (post restoration) (8/2011- 2/13). The ultimate aim of our ongoing study was to evaluate whether the sediment monitoring approaches we employed could resolve whether spatial or temporal differences in marine sediment accumulation/composition could be attributed to a) watershed development, and b) the Best Management Practices (BMP)/sediment control projects implemented by ARRA in Coral Bay."
