In-situ incubation of light-and-dark bottles for the estimation of phytoplankton productivity in Levittown Lake, Toa Baja, Puerto Rico
Description
This dataset contains tabulated-data of dissolved oxygen concentrations collected at Levittown Lake, Toa Baja, Puerto Rico. The standard light-dark method was used to determine the primary productivity in phytoplankton. The method consists in the in-situ incubation of two light-and-dark bottles for approximately four hours. Dissolved oxygen concentrations were estimated using the Winkler method. A total of twelve in-situ incubations were conducted on a monthly basis from April 2010 to June 2011. For each bottle incubated, two or three titrations were conducted and an average of the dissolved concentrations is calculated.
