PELD - ELPA | Continuous monitoring of the micro and mesozooplankton of the Patos Lagoon estuary and adjacent coastal area
PELD - ELPA | Programa Pesquisa Ecológica de Longa Duração no Estuário da Lagoa dos Patos e Costa Marinha Adjacente
Description
The micro and mesozooplankton of the Patos Lagoon estuary have been sampled monthly by the zooplankton laboratory of the Federal University of Rio Grande (FURG) at two locations inside the estuary (since Apr 2009) and another at the local adjoining area (since Nov 2009), near FURG´s marine aquaculture station. Mini-bongo nets fitted with 90 and 200 microns and callibrated flowmeters are being used to collect the samples. Temperature and salinity data as well as water samples to measure Chlorophyll a are also collected from each sampling site.
Geographic Description
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 (30º30’ S) to Rio Grande (32º12’ 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 Patos Lagoon estuary is strongly controlled by the discharge of tributary rivers and the action of predominant winds.
Purpose
The general purposes of this data bank are to provide information on zooplankton sampled in the Patos Lagoon estuary, and to identify long term trends on the zooplankton of the Patos Lagoon estuary.
Data quality
All samples are collected under the supervision of post-graduate students of the Zooplankton Laboratory, and the quality of data are checked before uploading in the data bank.
Methods
All zooplankton organisms present on subsamples of 1.25 to 50 % of the 200 µm mesh samples, were counted on a stereoscopic microscope and identified to the lowest taxonomic level possible. Copepod species were identified according to Björnberg (1981); Bradford-Grieve (1999) and Rose (1933). Barnacle nauplii according to Lang (1979; 1980) and the remaining species and/or groups using references on Boltovskoy (1981, 1999). All results are expressed in numbers of organisms.m-3.
