Seagrass Mapping Benthic photographs were taken along 50 m long transects, 12-15 m apart from each other and oriented perpendicularly to the pier. Photographs were taken using a surface deployed quadrat and camera array in navigable waters. Photographs were taken while snorkeling when precise navigation was not possible due currents, depth or unsafe navigation conditions were present (i.e. too shallow). Photographs were geotagged by synchronizing GPS coordinates collected during sampling and a specialized geotagging software (RoboGeo). Seagrass Cover was estimated at each site using Coral Point Counter software (CPCe). Seagrass cover countoures were created using Grapher (Golden Software)

Future • Impingement An extension to corroborate seasonality with better intervalometers and light sources.
Sedimentation Results from trace element (i.e. Cu, As, Pb) contents of sediments from traps. Samples were sent and analytical results are expected to arrive during January 2017. Evaluate the possibility of trace element transport along suspended sediments in Guayanilla Bay.
Seagrasses Complete sampling and analysis of seagrass distribution close to EcoElectricas pier at un- sampled sites. Evaluate the temporal distribution of seagrasses at sites close to the Outfall Station.
Water Quality Continuous Analysis of Water Quality at the Intake and Outfall Sites Monthly sampling of other sites. Intercalibration between sampling strategies. Intercomparison with previous studies.
Fosforescent Bay Expand monitoring to include determinations of the appearance of subsurface oxygen depletion that may affect the production of bioluminescence Evaluate alternative means of bioluminescence determination using economic photographic approaches. These may be suitable to expand stakeholders monitoring.
