Zooplankton data collected in the Romanian Black Sea waters between 1961 and 1969

The zooplankton dataset contains samples collected during 1961-1970, from different stations, from the Romanian Black Sea waters. Samples were collected from different depths, mainly monthly, covering in this way all seasons (spring, summer, autumn,winter). All samples were collected using the Baskakova net, with an opening of 36 cm diameter. Zooplankton samples were analyzed both from quantitative (density and biomass) and qualitative (list of species) point of view.
Horseshoe crab distribution records from East America and Asia

We assembled occurrence records (presence-only) for all four horseshoe crab species in Asia and Eastern America from our own observations, collaborators, scientific networks as well as through publishing a scratchpad site at http://horseshoecrabs.myspecies.info/. For many species, numerous distribution records exist in the literature, and we manually geo-referenced additional occurrence data from these sources.
Our knowledge on global distribution of the four extant horseshoe crab species is inadequate. The aim of this study (and the associated data set) is to improve our understanding of the current biogeographic distribution of horseshoe crabs. To do this we collated all available occurrence information for all four species on the Atlantic coasts of Central and North America, and the coasts of South-East Asia. Occurrence data from the four extant species of horseshoe crabs (Limulus polyphemus, Carcinoscorpius rotundicauda, Tachypleus gigas, and T. tridentatus) were compiled from recent literature, our scientific network, and own field work. The three Asian species C. rotundicauda, T. gigas and T. tridentatus were found to co-occur on the Indonesian islands Borneo and Java.

Macrozoobenthos collected from the longitudinal profiles in the Romanian marine waters between 1986-1990

The macrozoobentos dataset includes a number of 56 samples collected on the Longitudinal profiles (L) of the Romanian littoral between 8 m to 42m depths. Van Veen grab with a sampling area of 1/20 m2 was employed as a macrozoobenthos sampler. One replicate  was collected at every station. Sampling was done in autumn period (September, October).The samples have been analyzed qualitative (number of species) and quantitative (densities and biomasses). The macroinvertebrates have been identified at species level.
Monthly variation in the macrozoobenthic community structure in Monolimni Lagoon (Evros Delta, N. Aegean Sea)

The dataset contains data on the presence of macrobenthos from 2 stations in the Monolmni Lagoon in the Ervos Delta which were sampled monthly in 1998.
4 replicate samples were collected at each station for faunal analysis. Samples were taken using a Modified van Veen grab with a sample surface of 400cm² and depth penetration up to 20cm. A special net was used for the collection of the epibenthic decapods and small fishes. This net had a a  square opening of 40 cm on each side and it was pulled on the sediment along a 10 m distance. At each station, a sediment sample was taken with a small corer for particle size analysis and estimation of organic matter.
A number of datarecords are uncertain, and are therefore not included in Eurobis.

The results showed that the macrozoobenthic community structure and dynamics at low salinities  (0.3 - 6 psu) in Monolimni Lagoon were investigated monthly. Community structure showed an almost even seasonal periodicity. The main structuring factors of the community in the deeper outer part of the lagoon were water temperature and depth, and in the innermost part, where a Ruppia meadow occurred, were water temperature and predation pressure by crabs and gobies.
Italian official Adriatic (Mediterranean Sea) landings between 1953 and 2012

Italian annual landings (1953–2012) for the Northern and Central Adriatic Sea originated from official Italian statistics on the fishery, reported by the Italian National Institute of Statistics (ISTAT) from 1953 to 2004, and by the Institute for Economic Research in Fishery and Aquaculture (IREPA) from 2005 to 2012.
Until 2001, landings were published in the ISTAT annual bulletins (printed format) while after 2002 they were available in digital format. The method of landings data collection changed in 2005. ISTAT collected monthly landings data (census survey) at Marine Compartment level from Port Authorities using standardised paper templates, while IREPA performed sample surveys applying the Computer-assisted personal interviewing (CAPI) technique following ISTAT guidelines. In the dataset, landings are aggregated at the level of Italian administrative regions (Friuli Venezia Giulia, Veneto, Emilia Romagna, Marche, Abruzzo and Molise) and do not include discarded, illegal and unreported catches. In the original documents, species were cited with their common names, thus it was necessary to attribute them their scientific name. Common names reported in the original documents changed over time, and they were updated according to the actual official name as defined by the Italian Ministry of Agricultural, Food and Forestry Policies in 2008. Overall, information on 120 marketed categories are available in the dataset (15,077 records), but the taxonomic resolution of landings changed over time ranging from a minimum of 31 (1958) to a maximum of 81 categories (1955-1957). Marketed categories may include one or more species. Multispecies categories usually group taxonomically similar species, i.e. species of the same genus or family. The statistics are referred to landings from capture sea- and freshwater-fisheries in the Adriatic Sea landed by Italian boats.
Romanian Black Sea Zooplankton data from 1981 to 2000

The zooplankton dataset contains samples collected during 1981 2000, from different stations, from the Romanian Black Sea waters. Samples were collected from different depths, in different seasons. All samples were collected using the modified Juday net, with an opening of 36 cm diameter. Zooplankton samples were analyzed both from quantitative (density and biomass) and qualitative (list of species) points of view.
The sampling was carried out from standard depths with Juday net. A sample of 500 ml was collected from each depth or from bottom of Sea to surface by towing the netStudy ExtentThe current dataset extends from 1981 to 2000, from January to December, without a similar annual frequency. The samples were collected from the Black Sea, covering coastal, shelf, and offshore Romanian waters.Quality ControlData in the Romanian Black Sea zooplankton dataset were collected by experienced scientists. The data entry was done by a scientific team. The introduced data were checked by another scientist and the input errors were corrected, following the zooplankton datasheets.Method step description:This dataset was compiled from a historical collection of zooplankton datasheets. These data sheets were used as a protocol for zooplankton 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, name of the expedition, etc.); the equations used to calculate the abundance of zooplankton species; and data (identified species, individuals counted in the subsample, total abundance, and total biomass).The sampling was carried out from standard depths with Juday net. A sample of 500 ml was collected from each depth or from bottom of Sea to surface by towing the net. The samples were preserved with 80 ml of buffered 37 % formaldehyde solution/ 1000 ml of water sample. The mesozooplankton sample was homogenised, and quantitative and qualitative processing was performed. Organisms were counted in subsample(s) until each of the three dominant taxonomic groups reached 100 individuals. For the estimation of large animals‘ numbers, the whole sample was examined in a Petri dish or Bogorov Chamber.

Marine data from Natural Resources Wales (NRW) Technical Support (Research - Monitoring) Contracts, Wales

This dataset is comprised of marine benthic surveys created by Natural Resources Wales' (and previously the Countryside Council for Wales') technical support (research and monitoring) contracts since 1993. The surveys focus on benthic habitats (often referred to as 'biotopes') in intertidal, inshore (typically within 3nm) and subtidal areas. These surveys include the capture of many species records. Only the species records are available on the NBN Gateway. Some of the surveys were originally stored in the MNCR (Marine Nature Conservation Review) database created by JNCC but then transfered to CCW. (However, none were carried out as part of JNCC's MNCR officical survey programme). Original copies of all the surveys are now held in NRW's Marine Recorder database.
Purpose of data capture: To aid coastal zone and sea-use management and to contribute to the identification of areas of marine natural heritage importance.

Methods of data capture: The contract surveys were collected according to different methodologies. These include methods described in the MNCR Rational and methods report (Hiscock 1996) and CCW marine monitoring techniques described in CCW Contract Science Report No: 380 (Sanderson et al, 2001). Please see survey metadata for specific methodologies.

Data quality: High.
Romanian Black Sea Phytoplankton data from 1961 to 1970

The phytoplankton dataset includes samples collected from shallow to shelf Romanian waters, in the period 1961 - 1970, from March to November; there is no similar frequency each year. Dataset contains abundance data (cells per liter) and biomass (mg/m3) for individual phytoplankton taxa.
"Phytoplankton data collected in the Black Sea between 1960 and 1970 and processed by Hilarius Skolka and Nicolae Bodeanu. This dataset contains abundance data (cells per liter) and biomass (mg/m3) for individual phytoplankton taxa. Samples were taken by 1L Nansen bottle at  standard depths. The standard sedimentation technique for samples preparation (Morozova-Vodianitkaia, 1954) was used. Data were collected from coastal/shallow to shelf Romanian waters  from various transects such as: Constanta, Chituc, Tuzla, Portita, Mangalia etc.
Phytoplankton abundance was counted by specialists using data sheets which contained abundance per station. After counting all the individuals from a subsample under the microscope, the scientific team calculated the total phytoplankton abundance and biomass. For each record the maximum and minimum sampling depth is recorded."

IMMRAC is a purely voluntary registered nonprofit organization dedicated to the conservation of cetacean populations in the Eastern Mediterranean and in the northern Red Sea, through scientific research and public education. IMMRAC is a partner of ACCOBAMS. Research activities are under the academic auspices of the Institute for Maritime Studies in the University of Haifa. Open Sea research focuses on the socio-ecology of the resident bottlenose dolphin population through half-day surveys from inflatable boats and private yachts. Research activity along the 190 km-long Israeli Mediterranean coast is conducted throughout the year, weather permitting. 

IMMRAC collates shore-based and boat-based cetacean sightings, the latter from dedicated surveys as well as from platforms of opportunity, made by its own staff or reported to it by other parties. The latter are mostly backed by photographs or else, are indisputably accredited through careful interrogation by IMMRAC experts in real time and/or soon after the sighting, aided by a pictorial guide.

Some records had estimates, minimums, or ranges for group sizes - these were converted to numbers, minimum + 1, or the median number (rounded down), respectively, for the number of animals observed.
Historical landings from the Venice (Italy) fish market between 1905 and 1927

Historical landings from the Venice (Italy) fish market for the period 1905-1927 (with some temporal gaps) were retrieved and transformed into workable spreadsheets from statistical bulletins published by the Municipality of Venice, the "Società regionale veneta per la pesca e l'acquicultura" (Veneto regional society for fisheries and aquaculture) and by the historical scientific journal called "Neptunia".
At that time, Venice fish market was one of the most important in the area together with Rijeka (currently Croatia) and Trieste (currently Italy). Almost all fish caught in the Northern Adriatic Sea at time was sold to these fish markets. Landings are reported by their origin, i.e. capture-based aquaculture in the lagoon of Venice, capture freshwater-fishery (local rivers and lakes), Venice lagoon capture fishery and Northern Adriatic sea capture fishery. Species were reported with their scientific and vernacular names that were updated according to the World Register of Marine Species (WoRMS). Overall, information on 130 marketed categories is reported (1,192 records). However, the taxonomic resolution of landings changed over time, from a minimum number of 26 (1910) to a maximum of 108 categories (1919-1924). Marketed categories may include one or more species. Multispecies categories usually group taxonomically similar species, i.e. species of the same genus or family.

Northern Cyprus 2004: Loggerhead -amp; Green Turtles (aggregated per 1-degree cell)

The Marine Turtle Conservation Project is a project of the Marine Turtle Research Group and has been monitoring the nesting beaches of Northern Cyprus since 1992. The project is in collaboration with the Society for the Protection of Turtles in Northern Cyprus (SPoT) and the Department of Environmental Protection. In Northern Cyprus both green and loggerhead turtles nest. Green turtles in the Mediterranean are listed as critically endangered by the IUCN, with estimates suggesting that there are as few as 300-400 females nesting annually in this region. Loggerhead turtles nest in slightly greater numbers, with approximately 2000-3000 females nesting annually. Approximately 30 % of the green and 10% of the loggerhead turtles in the Mediterranean nest in Northern Cyprus.
