EDP Baixo Sabor: Phytoplankton - Ecological Monitoring Program [2016]

Description

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 6 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage

The data were collected in a single point in the Baixo Sabor reservoir, at a fixed station 1300 m upstream of the dam in the deeper zone of the reservoir.

Taxonomic Coverage

The taxonomic coverage of this dataset includes 6 kingdoms, 15 phylum, 17 classes, 48 orders, 77 families, 144 genus and 305 species of the list of the EU’s Water Directive framework. The actual observations encompass 5 kingdoms, 9 phylum, 10 classes, 18 orders, 23 families, 30 genus and 31 species. The identification was made, whenever possible, to species level; otherwise, the phylum, class, order, family or genus were specified.

Temporal Coverage

Project Data

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. A total of 1849 taxa records were obtained corresponding to 31 species and 11 genera. The most abundant species (>100 records) were Fragilaris crotonensis (phylum Ochropyta, class Bacillariophyceae, order Fragilariales) (198 records), Chroomonas acuta (Cryptophyta, Cryptophyceae, Pyrenomonadales) (167), Woronichinia naegeliana (Cyanobacteria, Cyanophyceae, Chroococcales) (142) and Eudorina unicocca (Chlorophyta, Chlorophyceae, Volvocales) (119), and the genera Anabaena (Cyanobacteria, Cyanophyceae, Nostocales) (122) and Cryptomonas (Cryptophyta, Cryptophyceae, Cryptomonadales) (121).

Sampling Methods

Sampling followed the procedures defined by the Portuguese National Water Authority in the protocol for sampling and analysis of phytoplankton quality element under the Water Framework Directive. In each sampling campaign, a two-step procedure was adopted. First (a) a water column profile for temperature and dissolved oxygen was perform using a multiparametric probe (b) the water transparency was measure using a Secchi disk (Secchi depth), and (c) the depth of the euphotic zone was estimated (2.5 x the Secchi Depth). Second, (a) water samples were collected, using an integrated water sampling device (hydrobios), from the surface to euphotic zone maximum depth; (b) samples were preserved in loco with Alkaline Lugol’s solution and transported in 48 hours to the laboratory. The samples were stored in a dark and cold place (1º to 4ºC) for a maximum period of 6 months. They were periodically examined and recompleted with Alkaline Lugol’s solution, whenever needed. In the lab, the analysis for identification (to the lower possible taxonomic level), quantification (cells/mL) and biovolume (mm3/m3) were carried out using sedimentation chambers and an inverted microscope (Utermöhl technique), as described in EN 15204:2006 (Water quality - Guidance standard on the enumeration of phytoplankton using inverted microscopy (Utermöhl technique)) and EN 16695:2015 (Water quality - Guidance on the estimation of phytoplankton biovolume).
