Fosforescent Bay Monitoring

Water Quality

• Monthly sampling of temperature, salinity,

turbidity, phytoplankton and cyanobacterial biomass indicators (chlorophyll and phycoerythrin), and colored organic matter fluorescence.

• Continuous Monitoring of pH, turbidity,

salinity, DO, temperature.

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

• f bioluminescence

determination using economic photographic

• approaches. These may be

suitable to expand stakeholders monitoring.
