Descrição
Phytoplankton data, species composition, abundance (cells/l) (SDN:P01: PU00M00Z) and biomass (mg/m3) (SDN:P01: WWBMM00Z) collected at coastal stations located in the 1n.m. Bulgarian Black Sea area and stations on a coastal-open sea transects in the Bulgarian Black Sea region, including the EEZ.
Registros de Dados
Os dados deste recurso de evento de amostragem foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 571 registros.
Também existem 2 tabelas de dados de extensão. Um registro de extensão fornece informações adicionais sobre um registro do núcleo. O número de registros em cada tabela de dados de extensão é ilustrado abaixo.
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.

Métodos de Amostragem
Phytoplankton samples were collected by CTD probe (SBE-911) with attached Niskin bottles at discrete depths, defined according to the in situ fluorimeter readings (0m - thermocline- deep chlorophyll a maximum), and 1m above the bottom or down to 75 m depth at the deeper stations.
| Área de Estudo | Sampling area: Bulgarian Black Sea - coastal stations located in the 1n.m. Bulgarian Black Sea area and stations on coastal-open sea transects in the Bulgarian Black Sea region, including the EEZ. Sampling period: 04.10.2007 - 21.09.2016 |

Descrição dos passos do método:
- Phytoplankton samples (1000 ml water sample) were fixed on board in 4% formaldehyde solution, buffered to pH 8-8.2 with disodiumtetraborate. Only samples integrated for the surface homogenious layer ( 0m - down to the thermocline) were analysed. In the laboratory the samples are concentrated down to 50 cm3 by slow decantation after storage for at least 20 days in a cool and dark place. Taxonomic identification and cell counts are done under inverted microscope (Nikon T300E) connected to a video-interactive image analysis system (L.U.C.I.A, Version 4.8, Laboratory Imaging Ltd, Prague) at 400x magnification by the Uteröhl (1958) method in Sedgwick-Rafter counting chambers. 400 cells are counted from each sample, while rare and large species are checked in the whole counting chamber (Moncheva and Parr, 2005/2015). The individual cell biovolume (V, μm3) is derived through the approximation of the cell shape of each species to the most similar regular solid, calculated by the respective formulas (Edier , 1979; Vadrucci et al., 2007), averaged over measurement of ten cells from each species. Cell bio-volume is converted to weight (W, ng) following Hatchinson (1967). Taxonomic nomenclature is according to the on-line data-base of World Register of Marine Species (WoRMS) http://www.marinespecies.org/ and the Black Sea phytoplankton check-list. The QC/QA of the data is performed following the quality control Guidelines for phytoplankton (Moncheva, 2010).
