Bycatch along Romanian Black Sea coasts 2010-2011

The present database represents the situation of dolphin bycatches along the Romanian coast during 2010 and 2011. The data were collected from the entire Romanian coast, from Sulina to Vama Veche.
The purpose of this dataset was to monitor the situation of Black Sea dolphins along the Romanian coast. 

In the Black Sea the cetaceans are represented by three species, Phocoena phocoena relicta, Tursiops truncatus ponticus and Delphinus delphis ponticus. The main threat and cause for the decline of the Black Sea dolphins are the fishing nets, so-called bycatches. For protection of the dolphin populations from Romanian Black Sea area in conformity with the objectives of the „National Action Plan for Conservation of Dolphins” and „Agreement on the Conservation of Cetaceans of the Black Sea, Mediterranean Sea and contiguous Atlantic Area”, with finance from European Union true the Sectorial Operational Programme – Environment, NGO „Mare Nostrum” started a series of activities in partenership with National Institute for Marine Research and Development „Grigore Antipa” Constanța, Danube Delta Biosphere Reserve Authority, National Agency for Fishing and Aquaculture, Natural Science Museum Complex „Dolphinarium” Constanța, Border Police Inspectorate of Constanța County. 

The present database presents the situation of dolphin bycatches along the Romanian coast during 2010 and 2011. The datas were collected from the entire Romanian coast, from Sulina to Vama Veche.
Ross Coral Mapping Project - NBN South West Pilot Project Case Studies

The results of dive surveys carried out by Purbeck Marine Research Unit, Canford School during 1994 and 1995 to record the distribution of Ross Coral Pentapora foliacea at the eastern limit of its range off the Dorset Coast.
These records are from the data holdings of Dorset Environmental Records Centre which covers both terrestrial and marine taxa, the majority dating from 1976 onwards but also including historical records. The database includes records from site and species surveys by staff and local naturalists, extractions of records from literature, records from other organisations which hold records for Dorset, and records sent in by the general public. The data quality is therefore variable but all records have been through a basic validation process by local experts before entry. This dataset has been submitted to the NBN Gateway as part of the South West Pilot Project Case Studies work.

Abundance - Biomass of benthic infauna from grab samples taken as part of an ecosystem assessment of Belfast Lough in 2012

This dataset contains information on the abundance - biomass of infauna found in sediment grab samples carried out in Belfast Lough as part of a mussel (Mytilus edulis) bed stock assessment and Crepidula (Crepidula fornicata) survey in September 2012. The main aim of the survey was to assess the stock of mussel beds in Belfast Lough and to survey the Crepidula population in Belfast Lough. The infaunal surveying was carried out using a 0.1m2 day grab and a 1mm sieve. Samples were taken at 50 stations over 5 days in September in 2012- abundance - biomass were recorded and infauna were identified to species level where possible. Particle size analysis - Carbon and Nitrogen analysis was also carried out at each station. The most abundant species found and most frequently recorded was the polychaete Melinna palmata.
"This dataset contains information on the abundance - biomass of macrofauna found in sediment grab samples taken from Belfast Lough in September of 2012. These samples were taken as part of the mussel (Mytilus edulis) bed stock assessment in Belfast Lough as well as investigating the presence of the invasive Crepidula (Crepidula fornicata) in these mussel beds. Crepidula (also known as slipper limpets are an invasive species in Belfast Lough. This species was originally found along the East coast of the Americas and they were first documented in Belfast Lough in 2009. Belfast Lough now contains the only viable population in Ireland.
Mussel dredge samples (taken using a 2ft wide mussel dredge with 30kg capacity), infaunal samples, particle size analysis samples and Carbon - Nitrogen samples were all taken as part of this survey. This dataset only contains the information regarding the infaunal samples. 
The methodology for collecting the infaunal samples is as follows; •A 0.1m2 day grab was used to take a sample of the sediment - associated infaunal communities.
• When the sample reaches the deck, a 250ml sample is taken for PSA and a further 25ml is taken for C - N analysis. The rest of the sample is carefully sieved to reveal any infauna.
• Fixed Formalin (4% buffered formaldehyde) is added to the remains of the sample and these are placed in labelled buckets.
• The samples are sent to accredited taxonomic laboratories were they are identified to as high a level as possible and weighed. The grab samples were taken on 5 separate days throughout the course of August - September 2012. Three different vessels were used in sampling. The “Osprey I” carried out sampling in Belfast Lough on 2012-08-21, 2012-09-06 - 2012-09-07. The “Swiftsure” (10m pot fishing boat) was used for sampling on 2012-09-13 and finally the RV Corystes carried out sampling on 2012-09-26. No successful infaunal samples were taken on 2012-08-21 and so this date does not appear in the dataset. The same survey equipment was used on board all vessels.

Dataset of the multidisciplinary research surveys in the seamounts of Ewing and Valdivia Bank (Walvis Ridge) - SE Atlantic

The dataset is the result of the sampling conducted between 2008 and 2010 on the R/V Vizconde de Eza.
The three multidisciplinary research surveys on board the R/V Vizconde de Eza (Secretaría General de Pesca Marítima) were performed in the seamounts of Ewing and Valdivia Bank (Walvis Ridge) as a collaborative work between Spain and Namibia trough the Instituto Español de Oceanografía (IEO) and the National Marine Information and Research Centre of Swakopmund (NatMIRC). Studies on biodiversity, acoustic and geophysics, hydrography, and seabird and cetacean observations were conducted.  A total of 15 823 km² were surveyed with a multibeam echosounder and 1462 km of seismic profiles, using an ultra-high resolution parametric sounder. The depth ranged between 218 m at the outcrop in the South-eastern sector of Valdivia Bank and 3000 m in the southern part of our study. A total of 210 species of fish, 60 crustaceans and 32 cephalopods were recorded. Species diversity increased by depth and four assemblages by depth strata were found: shallower (200-300 m); slope (300 - 800 m); upper deep (800 - 1300 m); and deep (1300 - 2000 m).

North Sea Benthos Survey

North Sea macrobenthos species density and abundance, measured on a regular grid of stations corresponding with ICES standard stations. All sampling was done in spring 1986.
The data presented is the result of the 1986 North Sea Benthos Survey, an activity of the Benthos Ecology Working Group of ICES. Benthic samples were taken in a standardised way, on a regular grid covering the whole of the North Sea, and analysed by scientists from 10 laboratories. Extensive work was done to standardise taxonomy and identifications across the different laboratories. A total of just over 1000 species were reported from 235 stations.
Lange-termijn trends in het macrobenthos van de Belgische Continentale Plaat

De globale doelstelling van dit project is kennis te vergaren betreffende lange-termijn variabiliteit in de biodiversiteit van het macrobenthos en de relatie met antropogene activiteiten op de Belgische Continentale Plaat.
The Belgian Continental Shelf (BCS) (surface : 2017 km²) is only 0.5 % of the North Sea surface, but it has a very high diversity in marine habitats and associated biological communities. Also, the socio-economic importance of the BCS is very high. As in most areas around the North Sea, a lot of anthropogenic activities, such as sea fisheries, maritime transport, military shootings, dredging activities and others occur on the BCS.The combination of the ecological and the socio-economic value of the BCS causes conflicts between both interests. Therefore it is very important to develop a sustainable management plan for the natural resources of the BCS. To obtain this goal, information and knowledge is required about:geographical distribution of the marine biological communities,the structure of these communities,their relationship with the physical and the chemical environment,the natural ecological and genetic variability, andthe nature and the effect of the anthropogenic influences on these ecosystem components. Macrobenthic organisms are good candidates for monitoring the short and long-term effects of natural and anthropogenic impacts on and within the marine environment because of their direct link with the sediment and with the processes that occur immediately above the sediments.The global objective of this project is to deliver a substantial contribution to the knowledge of the long term variability in the biodiversity of the macrobenthos and the relationship with anthropogenic activities.The specific aim of this website is to deliver an atlas with distribution maps of the macrobenthos of the Belgian Coastal Shelf (BCS) for the periods 1977-1983 and 1994-2000. Besides biogeographic and taxonomy information, which is given for each taxon, descriptive details on morphology, biology, ecology, habitat preferences and illustrations are given for a limited number a taxa (see list below). Eventually, by continuing monitoring programmes, our knowledge of different effects of antropogenic activities on the macrobenthos will aid in the development of a sustainable management plan for the Belgian Coastal Shelf.

Biological samples from the french oceanographic fleet's deep-sea cruises

Description of biological samples collected during deep-sea campaigns operated by the French oceanographic fleet since 2011. These data are acquired by underwater devices during the campaigns and then stored by Ifremer's CNDO (Centre National de Donnees Oceanographiques) Sismer. These data are mainly located in the Mid-Atlantic Ridge and around mainland France.
The Biocean database was designed to gather the extremely large volume of data collected from different deep-sea ecosystem studies conducted by Ifremer's department "Environnement Profond" and aims at facilitating ecosystem studies in the deep sea. It represents an important new resource for deep-sea ecologists and will have wide applications in biogeography, and biodiversity studies.
