The purpose of the diel study is to collect measurements for the determination of community primary productivity in Caño Boquerón and Puerto Mosquito during a diurnal cycle. These diel studies are part of a limnological analysis at Puerto Mosquito and Caño Boquerón to assess the principal factors affecting the hydrology and water-quality characteristics of the coastal waters and provide baseline information to the regulatory agencies responsible for the management and conservation of coastal waters. The investigation involves two coastal waters: Caño Boquerón represents coastal waters under disturbed conditions and Puerto Mosquito represents undisturbed conditions. Phytoplankton primary productivity and community primary productivity were assessed in the study using dissolved oxygen measurements. Community primary productivity (primary production measured for the entire aquatic system; Thomaz and others, 2001) minus phytoplankton primary productivity (primary production measured in water column) equals the primary productivity of the benthos organisms (e.g. periphyton, and macrophytes).
