Description

Phytoplankton and water quality parameters are analyzed monthly since 1993 at two stations in the Patos Lagoon Estuary and at one station in the surf zone of the adjacent Cassino Beach. This data series provides unique long-term information enabling the evaluation of natural and anthropic impacts in the estuarine and coastal region in southern Brazil.

Purpose

The general purposes of this data bank are to provide information on long term studies developed in the Patos Lagoon estuary.

Sampling Description

Study Extent

Phytoplankton and water quality parameters have been continuously sampled since 1993 i.e., the time series comprise over twenty years of environmental and biological data.

Sampling

The following physical water parameters are obtained in situ: temperature (mercury thermometer); salinity (optical refractometer or conductivity meter Yellow Spring, mod. 33 SCT); water transparency (Secchi disk). Surface water is sampled with a bucket and stored in the dark in plastic bottles for the analysis of dissolved inorganic nutrients and chlorophyll-a in the laboratory.

Quality Control

Responsible researchers and the classical methods are the same employed since the beginning of the time series. Thus, methodology influence is minimal. Technical assistance for sampling and nutrient analysis changed during the years, and also of phytoplankton counting (six persons), always under supervision of the responsible researchers.

Method steps

  1. For phytoplankton counting, surface water samples are stored in amber glass bottles and fixed with lugol´s solution (2%). Plankton is also concentrated by horizontal tows using a 20 μm mesh size plankton net and stored in glass bottles fixed with fomaldehyde (4%) neutralized with hexamethylentetramine.

Geographic Coverages

The Patos Lagoon at the southern Brazilian coastal plain (Rio Grande do Sul state) is the largest (10,360 km2) choked lagoon in the world stretching in a NE SW direction from the city of Porto Alegre (30°30’ S) to Rio Grande (32°12’ S). In the southern estuarine region, approximately 10 % of total area, a single and narrow inlet connects this lagoon to the Atlantic Ocean. The major tributary rivers at the northern and central areas of Patos Lagoon, and the São Gonçalo Channel at the southern area, are significant freshwater sources from an extensive drainage basin. The hydrodynamics of the Patos Lagoon estuary is strongly controlled by the discharge of tributary rivers and the action of predominant meteorological factors like winds, rainfall and evaporation.
