Gulf. The investigations in this study have focused on the area (Bolinao Bay) between the northeast mainland of Cape Bolinao, Santiago Island and Cabarruyan Island. The bay has three inlets / outlets. The two up in the northern part of the bay are connected strait out to open water. However, the southern entrance is connected to Tambac Bay which also has a lot of aquaculture activity. The Tambac Bay was also affected by fish kill episodes. The studied bay are relatively shallow and the average depth in most of the area are less than 6 meters deep.

1. Environmental monitoring and modelling of aquaculture in risk areas of the Philippines
Preliminary information from Bolinao, Pangasinan, Philippines
Data collected
Bathymetry (depth recordings) of the area
Tidal range and current speed, direction and dispersion
Physical parameters - Temperature, turbidity, salinity, oxygen, profile
through the water column
Water quality – chlorophyll, phosphorous, nitrite, ammonia
Sediment analysis (biological and chemical)
Weather data wind direction, speed, temperature
