Observatoire Pelagis boat surveys 2003-2016

Original provider: Observatoire PELAGIS UMS 3462 University La Rochelle - CNRS Dataset credits: Observatoire PELAGIS UMS 3462, University La Rochelle - CNRS - Agence des Aires Marines Protégées - Direction de l'Eau et de la Biodiversité Abstract: Since 2003, the Observatoire PELAGIS (La Rochelle University) participated to annual halieutic surveys, led by the IFREMER, to collect data on the distribution of marine top predators in order to estimate their relative abundance and preferred habitats in the Bay of Biscay, the Channel and the North Sea.
Each year, three observers take place on board the vessel “Thalassa” to record sightings of seabirds, marine mammals, large fish and fishing boats, from dawn to dusk. Following distance sampling methods, visual censuses are made by two observers (while the third observer is resting) from the upper platform of the boat (min. 14m above the sea level). They are placed on each side of the deck, looking ahead for marine predator with an angle of 180°. For each sighting, the species and the number of individuals are recorded, as well as the behaviour, distance and angle (upon request). Purpose: One of the main advantages of this survey lays in its ecosystemic approach, which provides information on all the components of the food web (from planktonic organisms to predators) as well as data on the environmental parameters (sea surface temperature, salinity…). Interactions between prey and predators are complex in marine ecosystems, which are submitted to strong spatio-temporal variations. Thanks to ecosystem-based surveys, observed distributions and densities of marine predators can be related to the occurrence of their prey, providing to scientists and managers a better understanding of the marine ecosystems structure. Supplemental information: [2017-01-05] sighting records in 2016 were appended. Time and group size of the sightings are not available online. They may be released upon request.

Counts of seabirds, marine mammals and other megafauna during POLARSTERN cruise ANT-XXVIII/5 - biodiversity excerpt as Darwin Core Archive

Please note: Abstract created by PANGAEA data editor using Jungblut et al. (2017). Marine top predators (seabirds, marine mammals and other megafauna) were counted during POLARSTERN cruise ANT-XXVIII/5 crossing the Atlantic from Punta Arenas to Bremerhaven in spring 2012. Continuous half-hour transect counts were conducted by two observers from the bridge, situated approximately 18 meters above sea level, throughout daylight hours and while the vessel maintained its traveling speed (see Joiris -amp; Falck 2011).
Due to the width of the bridge, observations were limited to a 90° angle from the bow to one side, as it was impractical for one observer to simultaneously cover both sides. Species were initially identified with the naked eye and confirmed using binoculars (8 – 10 times magnification). Photos were used in retrospect to help identify rare or hard to classify specimens. Individuals following or circling around the ship were only counted once in a 30 min interval (i.e. during one 'transect count'). Water temperature and salinity were continuously and automatically recorded by a thermo-salinometer installed at the keel of the Polarstern (approximately 10 meters below sea level). Depth data were obtained either from the vessel's echosounder or hydrosweep. Data extraction was carried out from the DShip data system on board.
Benthic fauna of the Southwest Alentejo and Vicentine Coast Natural Park (SW Portugal) collected in August 2011

A macrozoobenthos species list is provided, based on datasets originated from infra and upper circalittoral samples (10 to 53 m depth) collected in the soft sediment bottom off Sines within the marine area of the Southwest Alentejo and Vicentine Coast Natural Park (SW Portugal). Species composition and  abundance per sampling station are provided.
The dataset provides a species list originated from infra and upper circalittoral samples (10 to 53 m depth) collected in the soft sediment bottom off Sines within the marine area of the Southwest Alentejo and Vicentine Coast Natural Park (SW Portugal), during one dedicated sampling survey in August 2011. Triplicate sediment samples were collected at each georeferenced sampling site with a Smith-McIntyre grab with a sampling area of 0.1 m2. In the laboratory the samples were analysed for species composition and abundance, and sediment grain size as well as organic matter content were determined for each sampling site. The work was carried out in the framework of the MeshAtlantic Project (Atlantic Area Trans-national Programme), aiming at classifying and mapping the benthic habitats and associated communities of the study area using the EUNIS system.
Mesopelagic Crustaceans of the North Western Portuguese Coast between 1998 and 2000

The objective of this data collection was to study the structure of the mesopelagic ecosistem off the Northwestern Portuguese coast which is composed by planktonic and nectonics organisms. Mesopelagic organisms live during the day concentrating in big numbers in deeper depths while during the night migrates towards the upper layers.  The data was collected aiming to study the composition and the Dynamics of the mesopelagic community and their trophic relations with the fish in the area. Data was collected with an Isaac-Kidd midwater trawl in May 1998 and 2000 and February 1999, together with environmental parameters as temperature, salinity, etc.
The results showed a strong temporal variability of the abundance of the diferent taxonomic groups in study. The analysis of the results lead to the conclusion that, being the sampling locations and methods used were similar for the studied period, the big variability in the abundances and taxa have been found must be related mainly to the season of the year in which the sampling was performed (winter season for 1999 and late spring for 1998 and 2000).
1778-1998 Ivor Rees North Wales Marine Fauna Ad-hoc sightings shore and ship-based surveys

A historical collection of marine species records from Academics at the University of North Wales, Bangor collated from ad-hoc sightings, shore and ship based surveys collated by Ivor Rees.
Species records from historic literature, from surveys conducted by the University of North Wales and incidental records noted by staff. A variety of methods were used most of which are not documented on the cards. The average resolution of the subtidal records is 1km but shore records are more accurate averaging approximately 250m resolution and often more accurate than this. Species identification is likely to be generally very accurate. Many of the names originally recorded have changed and the current valid name has been identified.

Observatoire Pelagis sightings from fishery surveys 2004-2009

Original provider: Observatoire PELAGIS UMS 3462 University La Rochelle - CNRS Dataset credits: Observatoire PELAGIS UMS 3462, University La Rochelle - CNRS Abstract: Regulation (EC) No 812/2004 of 26 April 2004 is intended to assess the incidental catch of cetaceans in fisheries and to reduce bycatch in some fisheries. This regulation requires plans observation on vessels over 15 meters operating in pelagic trawl or large vertical opening in ICES zones VI, VII, VIII and IX, and vessesl over 15 meters operating with set nets in ICES VIa, VI-a,b and VIIIa,b,c and IX.The Ministry of Agriculture and Fisheries (Directorate of Marine Fisheries and Aquaculture - DPMA) is responsible for the implementation of the Regulation for France. An observation program of incidental catches of cetaceans started in 2006 on the French metropolitan coast.
The sampling plan provides coverage of 5% of the fishing effort for gillnets over 15 m in area VIII. For pelagic trawlers over 15m, a 5% coverage of the fishing effort has also been planned except for VI, VII and VIII where a coverage of 10% is required from December 1 to March 31.In addition, for vessels under 15m, pilot projects have been implemented by using on board observers. For simple pelagic trawls, a coverage rate of 5% of the fishing effort has been applied. For netters, a 1% coverage of the fishing effort has been targeted. This dataset gathered sightings made during these surveys together, but DOES NOT INCLUDE ANY BYCATCH DATA. Purpose: Implemented in 1983 in European waters, the Common Fishery Policy (CFP) is the marine translation of the Common Agricultural Policy (CAP). Its goals are manifold including estimating and reducing the total incidence of non-target species bycatch. Since 1992, the Habitats Directive required bycatch monitoring by European Union (EU) Member States. In line with commitments towards individual protected species, incidental catches are addressed under Article 12(4) which establishes an obligation to address, inter alia, by-catches: ‘Member States shall establish a system to monitor the incidental capture and killing of the animal species listed in Annex IV(a). In light of the information gathered, Member States shall take further research or conservation measures as required to ensure that incidental capture and killing does not have a significant impact on the species concerned’. The presence of observer on board is a good opportunity to collect data from live animal distribution and relative abundance, and provide additionnal data (considered as data collected on platform of opportunity). Supplemental information: Time and group size of the sightings are not available online. They may be released upon request.

Subtidal macrobenthos monitoring in function of a foreshore suppletion at the Belgian coast, period 2013-2016

What ecological effects does a foreshore suppletion, and a beach suppletion, have on the marine ecosystem in the intertidal and shallow surf zone (
This dataset contain the macrobenthic data collected in the subtidal area. Macrobenthos are the biota that lives in the sediment and are retained on a sieve of 1mm. The sampling design for the monitoring is following the BACI-design (Before After Control Impact), with a control area with similar habitat characteristics outside the influence of the suppletion activity. There is sampled before the suppletion and in the following two years after suppletion. In this BACI-monitoring, the seasonal aspect is taken into account, by taking samples in spring (March) and autumn (September). In the subtidal area, three depth strata were determined to investigated the influence of the suppletion outside the suppletion area. Stratum a (between low water line and -2m TAW) is the area were the foreshore suppletion is executed. Stratum b and c are taken respectively the depth zones -3m to -4m and -5m to -6m TAW. The amount of sampling locations was determined by the client and determines 15 points for each sampling moment. That amount of samples was via a systematic random stratified strategy distributed over each stratum (5 in each strata). The samples were taken with a Van Veen grab (0.1m²). The samples were sieved alive on a 1mm sieve and then fixed with an 8% formaldehyde-seawater solution. The sieved material is stained with eosin. All biota were determined and counted to species level following a standardized taxonomic discrimination protocol. This to determine the determination level and if certain life stages (larvae, juveniles) need to be discriminated. The biomass is determined as wet weight. All macrobenthic samples were taken following the ISO16665:2005(E)) (“Water quality – Guidelines for quantitative sampling and sample processing of marine soft-bottom macrofauna”). Moreover, the analyses (identification, counts and biomass) were conform NBN EN ISO/IEC 17025 standard executed (cfr. BELAC nr. 315-TEST: date 28/04/2016, valid until 05/03/2020).
