Machado, R.C.A.; Feitosa, F.A.N.; Koening, M.L.; Flores Montes, M.J.; Bastos, R.B., and Jales, M.C., 2014. Phytoplankton productivity and hydrology of Porto de Galinhas reef ecosystem (Pernambuco, Brazil). Porto de Galinhas beach is located on the south coast of Pernambuco, Brazil, around 50 km from Recife, has sandstone fringing reefs, and has intense tourist activity. To contribute to the environmental water quality, the phytoplankton biomass and productivity were analyzed, as well as some hydrological parameters at three fixed collection points. Water samples were collected in 3 months of both dry and rainy seasons, from the water column surface, at three fixed points between the reef and the beach, at high and low tides and diurnal spring tides. Temperature ranged from 26°C to 31°C, salinity ranged from 33 to 37, the saturation index of dissolved oxygen ranged from 97.16% to 174.54%. Nitrite and phosphate were lower than 1 μmol L−1, nitrate was
