Romanian Black Sea Phytoplankton data from 2001 to 2005

The dataset contains phytoplankton data collected in the Black Sea between 2001 and 2005 and processed by Andrei C., Anghel A., Boicenco L., Ionescu C., and Sburlea A. The data were collected from shallow to shelf Romanian waters from various transects such as Sulina, Mila 9, Portita, and Sf. Gheorghe (northern zone, strongly influenced by the freshwater input from the Danube Delta) to Constanta, Mangalia, and Vama Veche (southern zone). The sampling was carried out from standard depths with Niskin bottles. From each depth was collected a sample of 500 ml. The standard sedimentation technique for sample preparation was used (Morozova-Vodianitkaia, 1954). The scientific team identified and counted the phytoplankton species from a subsample with an inverted microscope and calculated the total abundance and biomass of each species. This dataset was compiled from a collection of phytoplankton datasheets and contains abundance (cells per liter) and biomass (mg/m3) data for individual phytoplankton taxa.
This dataset was compiled from a historical collection of phytoplankton datasheets. These data sheets were used as a protocol for phytoplankton sampling and analysis. They provided information about the metadata (sampling transect, station number, coordinates of the sampling station, sampling depth, sample collection date, name of the researcher who processed the sample, etc.); the equations used to calculate the abundance of phytoplankton species; and data (identified species, cells counted in the subsample, total abundance, and total biomass). Samples were concentrated by sedimentation and surface water removal to increase the phytoplankton density in the sample by following the standard sedimentation technique for sample preparation (Morozova-Vodianitkaia, 1954). After the volume of the concentrated sample was measured, a subsample of 0.1 ml was taken from the concentrated sample, poured into the counting chamber, and analysed under an inverted microscope, in order to identify and count all the phytoplankton species. Phytoplankton abundance per litre was calculated by the following equation: N = V1/V2 x n x 2, where N is the number of cells per litre of water, V1 is the volume of the concentrated sample, V2 is the volume of subsample, n is the number of cells counted in a subsample and 2 is the multiplication factor (Morozova-Vodianitkaia, 1948; Bodeanu, 1987 - 1988). The phytoplankton biomass was determined based on morphometric measurement of phytoplankton units. The biomass of phytoplankton per cubic metre of water was calculated by multiplying the abundance with the average wet weight of the species, following the average weights tables elaborated by Morozova-Vodnițkaia (1948; 1954) and Pițîk (1950), modified and updated by Bodeanu N. and Ruță G. (1995).

Marine Recorder Snapshot extract of surveys entered by JNCC

This dataset consists of surveys entered by JNCC.
The UK Marine Recorder public snapshot is an aggregated UK-wide marine dataset, published on a 6monthly basis. Data are collated by JNCC from publicly accessible data provided to JNCC by UK governmental and non-governmental conservation bodies from data holdings within each organisation’s internal “Marine Recorder” marine data management database application.

IOW Natural History - Archaeological Society Marine Invertebrate Records 1853- 2011

This dataset contains records of cnidaria, decadopa and echinoderms for shores and inshore waters in the vicinity of the Isle of Wight. Some data is historical but new sightings are being added to the dataset. Therefore it is not yet complete.
Purpose of data capture: The majority of the records have come from volunteers as part of the activities of the Isle of Wight Natural History and Archaeological Society whose objectives include the promotion and advancement of the study of the flora, fauna, geology and archaeology of the county.

Methods of data capture: Historic data before 1970s has come from books and journals. Data from the last 40 years has mostly come from ad hoc field survey by local experts and enthusiasts, though there have been some targetted surveys, including surveys done for the Nature Conservancy Council.

Geographical coverage: Isle of Wight and nearby waters. The records are largely ad-hoc and coverage is incomplete. The records in this dataset were provided with four or six figure grid-references but these grid references refer to the approximate central location of sites and hence may not represent the actual location of the species occurrence.

Temporal coverage: From 1853 to 2011. Records up to 1980s are generally to year only; after this time records are more usually to MM/YY or DD/MM/YYYY.

Data quality: Records from 1980s and onwards have been checked and confirmed by a local expert; prior to this the records have been scrutinised and assisgned to taxons in line with recent taxomonic developments.
