Monthly abundance of dominant phytoplankton species at 2 permanent phreatic lagoons representing in Doñana.

The dataset contains Phytoplankton records of samples collected at Baixo Sabor reservoir during the first year of the Ecology Monitoring Program (PME) of Baixo Sabor Hydroelectric Scheme, promoted by EDP – Energias de Portugal, S.A. Samples were collected in the deeper zone of the reservoir, at a fixed station 1300 m upstream of the dam, in 6 campaigns carried out between March and October of 2016. The targeted taxa were phytoplankton species, included as biological quality element for ecological quality in the framework of the EU’s Water Directive.

This georeferenced dataset describes a 25-year (1986-2010) monitoring studies of phytoplankton abundance and biomass in Lake Candia.

Average values along photic zone of phytoplankton cell density collected in the Lake Bidighinzu

Chlorophyll concentrations are provided from 6 depths (0 to 60 m) from the LTER- Marechiara Station in the Gulf of Naples on 4 seasons, 2012. The four data were chosen as to represent differen phases in the seasonal cycle of plankton in the Gulf of Naples

This dataset includes Chlorophyll a concentration in μg/L. Measurements of Chl a were made on discrete water samples collected monthly in the upper 20 meters layer at sampling station Ghiffa (45°58’30’’N; 8°39’09’’E) from January 1984 to December 2018. Chl a measurements derived by spectrophotometric technique in the period from January 1984 to December 2009, while from January 2010 to December 2018 measurements derived from vertical profiling instrument (FluoroProbe).

Data on biodiversity of Lake Ohrid and Lake Prespa

Data refer to on-site measurements and water samples collected in the mesotrophic eastern and eutrophic western basin of Lake Balaton. The data sets covers various physicochemical variables including water temperature, conductivity, pH, total suspended solids, Secchi depth, light extinction coefficient and chlorophyll a concentration for phytoplankton. Samples were collected with a tubular water column sampler.
