Dataset on coastal water quality in an Atlantic sea bass farm site in Sines, Portugal

The dataset is composed of water quality parameters distributed in time (date and time) and space (station ID, latitude, longitude, and depth). Data was collected at the surface and along the water column in 4 sampling stations placed along sea bass aquaculture cages: : station 1 (37.93272, -8.855261), station 2 (37.92932, -8.851303), station 3 (37.92775, -8.847949), station 4 (37.92482, -8.843557). Sampling took place in six field campaigns on 29/06/2018, 25/10/2018, 12/03/2019, 30/04/2019, 23/05/2019 and 29/07/2019. The dataset comprises two data files: (i) discrete data from laboratory analysis (Suspended Particulate Matter (SPM), Turbidity (Tur), dissolved nutrients (NH4+, NO3- + NO2, PO43-, and SiO2) , phytoplankton pigments (Chlorophyll-a (Chl-a), Fucoxanthin (Fuco), Peridinin (Peri), Chlorophyll-b (Chl-b), Alloxanthin (Allo), Zeaxanthin (Zea), 19-Hex, 19-Butanoyloxyfucoxanthine (19-But)) and microscopy data (relative abundance of Bacillariophyceae, Dinophyceae, Haptophyceae , Prasinophyceae, Euglenophyceae, Cryptophyceae, and Cyanophyceae; and relative abundance of potentially harmful species) and discrete data acquired with the multiparametric sonde (Dissolved Oxygen (DO), pH); (ii) continuous data casted along water column profiles with the CTD probe (Temperature (T) and Salinity (S)).
