L'Hippo-ATLAS a pour objectif de collecter des données d’observations sur les espèces d’hippocampes et de syngnathes des côtes d'Europe et de Méditerranée. Ce projet a pour objectifs de afin de préciser leur répartition ; de constituer une base photographique pour étudier et illustrer leur variabilité ; de collecter des données sur leur habitat dans le but de mieux comprendre leur mode de vie et leur vulnérabilité. Les données d’observation sont collectées par des plongeurs, pêcheurs et naturalistes amateurs. Un outil de saisie en ligne est disponible sur le site internet de Peau Bleue. Au 01/01/2011, la base contient environ 220 données. Celle-ci est complétée annuellement. Outre les données essentielles (espèce, lieu, date, observateur), sont notamment notés facultativement pour chaque observation : le sexe, la taille, la coloration, la profondeur, le substrat.
Vertical distribution of the free-living Plathelminthes (Turbellaria) from the sandy beaches of the Belgian coast in 1985 and 1986

Density and biomass of meiofauna for 6 sandy beaches (Knokke, Mariakerke, Oostende, Heist, Bredene, Zwin) along the Belgian coast sampled between April 1985 and May 1986. The data were digitized by VLIZ from the original report: Jouk, P. (1992). Studie naar de ecologie van de vrijlevende Plathelminthes (Turbellaria) van de zandstranden van de Belgische kust. PhD Thesis. Limburgs Universitair Centrum: Diepenbeek. 2 volumes pp.
Quantitative analysis of meiofauna samples with special attention to the Turbellaria. Samples were taken in six localities along the beaches of the Belgian Coast (Knokke, Mariakerke, Oostende, Heist, Bredene, Zwin) using a core (0-40 cm depth). The core was further divided into layers of 0-2, 2-4, 4-6, 6-8, 8-10, 10-12, 12-14 and 14-20 cm. Meiofauna was identified to species level, while Nematoda, Harpacticoida, Gastrotricha and other meiofauna organisms were counted only to the general taxon-level. This data can be used to investigate the participation and the importance of Turbellaria in the total meiofauna, in terms of both density and biomass. Moreover, the sampling includes a full-year cycle, whereby the temporal evolution of the meiofauna can be examined too.
Zooplankton abundance and biomass from the RADIALES time series programme (N-NW Spain)

"Zooplankton abundance and biomass data collected within the framework of the RADIALES time series monitoring programme, carried out by the CSIC-IEO. The sampling is undertaken monthly from 1991 at a series of stations located along five transects perpendicular to the North and Northwest Spanish coastline.
Sampling protocol varied slightly beween transects: oblique hauls with a 200 µm mesh-size Bongo (stations off Vigo) or Juday-Bogorov (Coruña) net; vertical hauls with 200 µm mesh-size WP2 net (off Cudillero and Gijón transects, and Santander from 2013 onwards); and oblique hauls with 250 µm mesh-size Juday-Bogorov (Santander until 2013). The nets were towed from 100 m (50 m for the Juday-Bogorov at the Santander transect) or 5 m above the bottom at shallower stations to the surface.

In all cases, the samples for abundance were preserved in 4% tetraborate-buffered formaldehyde for subsequent counting and taxonomic identification under a stereoscopic microscope. The biomass samples were filtered and dried at 60 ºC during 48 h before weighing to estimate the dry weight. The samples for biomass collected with the WP2 net (Cudillero, Gijón, and Santander since 2013) were split into three size-fractions: 200-500 µm, 500-1000 µm, and > 1000 µm. "
Polychaetes from two subtidal rocky shores of the North coast of Crete, collected for the NaGISA project 2007-2008

This dataset contains occurrence records of subtidal polychaetes (Annelida) from two midlittoral rocky shore sampling sites in northern Crete (Greece).
Samples were collected for a monitoring project of midlittoral rocky shores in Crete, in the framework of the NaGISA project (Natural Geography in Shore Areas, http://www.coml.org/projects/natural-geography-shore-areas-nagisa). 
The two sampling sites are characterised by a continuous hard bottom habitat with dense algal coverage and a moderate wave exposure and are not impacted by detectable anthropogenic activity. At each site, five random replicate units were collected from each depth of 1m, 5m, 10m, 15m and 20m by placing a plexiglas frame (25x25 cm) on the substrate and scraping the framed area completely. The samples were then collected with an underwater suction device working with pressure from a diving bottle. Samples were washed through a 0.5 mm mesh sieve and fixed in 99% ethanol. In the laboratory, all samples were identified to the most precise taxonomic level possible, using the most recent literature for the taxon.
Harpacticoida from an intertidal flat in the Chernaya River estuary (White Sea)

Data of harpacticoida from intertidal flat of the Chernaya River estuary, Gulf of Kandalaksha, White Sea in July-August, 2000.
The sampling was carried out during five sessions (16 subsamples each, by syringe corer 1.0 cm2), repeatedly on the same plot, a silty-sandy intertidal flat of the estuary. Salinity values varied between 16 and 20 ppm.
Eastern Mediterranean Syllidae from three locations in Crete and Israel

This is a combined dataset on Syllidae (Annelida, Polychaeta) originated from two projects: NaGISA (Natural Geography in Shore Areas, a long term monitoring project following a global protocol) and a study on the Benthos of Haifa Bay.
Specimens from Israel were collected on 31.5.2009 and 11.10.2009 in Haifa Bay, (Israel, Eastern Mediterranean Sea) from soft sediments of mixed grain sizes in shallow waters. Sediment samples were taken with a Van-Veen grab (KAHLSICO, model WA265/SS214) 32x35cm, volume 20 l, penetration 20 cm. The sediment was preserved in buffered formalin 10% for 3-7 days, then sieved through a 250 µm mesh sieve and subsequently stored in 70% ethanol. 
Specimens from Crete were collected in September 2007 and June 2008 from two sites in northern Crete characterized by a continuous hard bottom habitat with dense algal coverage and a moderate wave exposure. At each site, two vertical transects with sampling depths at 1 m, 5 m, 10 m, 15 m and 20 m were defined and five replicates were taken from each transect and depth.
Samples were collected by means of SCUBA diving according to the NaGISA protocol (Iken and Konar 2003). A plexiglas frame (25 x 25 cm) with a net of 0.5 mm mesh size attached to its top opening was placed onto the rock and the surface within the frame was scraped off. The sample was collected by a manually operated suction device, supplied by air from an extra scuba tank. Large particles (>2 cm) were collected manually after suction. The samples were subsequently washed through a 0.5 mm mesh sieve, fixed and preserved in 99% ethanol. Specimens were examined under an Olympus SZx12 stereomicroscope and an Olympus BX50 microscope and identified by employing the most recent literature on Syllidae (e.g. Nygren 2004, San Martín 2003, 2005, San Martín and Hutchings 2006). The syllid records from the NaGISA project are also contained in the full dataset "Polychaetes from two subtidal rocky shores of the North coast of Crete, collected for the NaGISA project 2007-2008."

Species and abundance records by fishermen, on annual basis, for the period 1999-2011. Responsible for these records is the Department of Fisheries and in particular the Regional Agency of Arta.
The records from fishermen calendars were collected from Fishing Cooperatives of Arta and officialy submitted to the Fisheries Department of Arta. Fishermen recorded the fish species they caught, their weight and their value.
Monitoring of birds in the Voordelta

Port of Rotterdam is carrying out the Project Mainport Development Rotterdam, PMR, expanding the port with 1,000 hectares through suppletion of sand in the shallow coastal Voordelta area in the North Sea. As the Voordelta has the status of protected nature reserve (Natura2000 area), the loss of habitat, caused by the expansion of the port, must be compensated for. As part of the compensating measures, the Dutch national government established a series of protected areas in the Voordelta region and is following the effects of these measures.

This dataset contains aerial counts of birds in the “Voordelta”. The set exists of a pre-protected status data (2003 – 2007) and a post-protected status (currently still under embargo).

Loggerheads in the Adriatic Sea

The aim of this project is to investigate the movements performed by loggerhead turtles in the Adriatic sea. The Adriatic sea is home to a quite large number of turtles, especially loggerheads, representing one of the best feeding areas within the Mediterranean Sea. Both juveniles and adult loggerheads frequent this area, and are thought to perform seasonal migrations, especially in response to changes in environmental parameters (especially temperature).
AdriaWatch project

The ADRIA-Watch project is a scientific observatory for large marine vertebrates of the Northern Adriatic Sea. Data are collected and pooled together into one single database, working towards a better understanding and dealing of the problems affecting the large inhabitants of the area and to promote public awareness. ADRIA-Watch collects data on sightings and strandings of Cetaceans (dolphins and whales), marine turtles and sharks along our coasts. ADRIA-Watch also contributes to a sharing of knowledge: web site, public conferences, scientific seminars, didactic material and educational projects. In the framework of this project 5 satellite-tracked loggerhead turtles will be released in 2006, from five different sites in the northern Adriatic sea, from both Eastern (Slovenian and Croatian) and Western (Italian) shores.

IFREMER/Kélonia satellite tracked late juvenile loggerhead sea turtles from Réunion Island 2008-2012

Satellite data from tracking study conducted on juvenile loggerhead sea turtles in the Indian Ocean.
Eighteen individuals were fitted with transponders and tracked from Réunion Island (21.2°S, 55.3°E) in order to investigate movements and diving patterns. Nine turtles swam north towards Oman (20.5°N, 58.8°E), where one of the world’s largest rookeries of loggerheads is located. Three individuals travelled south towards South-Africa and Madagascar, countries that also host loggerhead nesting grounds. Fourteen of the transmitters relayed diving profiles. A dichotomy between diurnal and nocturnal diving behavior was observed. A greater number of shorter dives occurred during the day. Diving behavior also differed according to movement behavior as individuals spent more time in subsurface waters (

Zariquiey Collection. Biological Reference Collections ICM CSIC.

The Zariquiey Collection is the collection of crustaceans donated by Dr. Ricardo Zariquiey Alvarez (1897-1965). Dr. Zariquiey Alvarez collaborated with the Fisheries Research Institute of Barcelona (origin of the current ICM), and donated his collection of crustaceans, and the associated library to the Institute. The Zariquiey collection is part of the CBR and is mainly composed by Decapod Crustaceans.
Dr. Zariquiey Álvarez, like his father, Dr. Ricardo Zariquiey Cenarro (1870-1943), was a prominent pediatrician and carcinologist. His collection of crustaceans grew with their own personal contributions and with contributions from their international contacts. Dr. Zariquiey Alvarez founded the Group of Carcinologic Studies, with Dr. I. Gordon (British Museum), Dr. J. Monod and Dr. J. Forest (Museum of Natural History, Paris), and Dr. L.B. Holthuis (Museum of Leiden). The best known and studied reference of his works is "Crustáceos Decápodos Ibéricos", published posthumously in 1968. His meticulousness and precision can be seen in the careful conservation of his specimens. He made important taxonomic contributions, including new types. Of the currently catalogued specimens there are types of 5 species. The collection contains specimens mainly from the Western Mediterranean (86%; especially the Catalan Mediterranean) and NE Atlantic (7%; Gulf of Cadiz, Portugal, Galicia, Cantabrian Sea, Bay of Biscay, France, Scandinavia, the British Isles, North Sea). There are also important contributions from other areas of the Mediterranean (Italy) and Atlantic (Morocco, Canary Islands, Senegal, Gulf of Guinea, Angola, United States, Mexico, Venezuela, Brazil, Argentina); and the Red Sea

Abundance of Echinothrix diadema and its substrate coverage in the Mombasa Marine National Park and Reserve (Kenya) in September-October 1997

Absolute abundance of Echinothrix diadema in the Mombasa Marine National Park and Reserve in September-October 1997, together with percentages of substrate cover (seagrasses, algae, corals, sediment) at the different sampling locations. The data were digitized by VLIZ from the original report: Van Hout, T. (1998). Patterns of distribution of Echinothrix diadema (Echinodermata: Echinoidea) in the Mombasa Marine National Park and Reserve, Kenya. MSc Thesis. Vrije Universiteit Brussel: Brussel. 71 pp.
The field studies were carried out in the inner reef lagoon of the Mombasa Marine National Park (MMNP) and the adjacent Mombasa Marine National Reserve (MMNR). Also the outer reef (only at the park’s side) was investigated for the presence of E. Diadema. During one month (29/9/97-24/10/97), surveys were made at low tide when the water reached a
depth maximum 6 m, in the deep channel. Both locations (park and
reserve) were subdivided in four different zones along the reef. A minimum of eight circle samples was laid in each zone, with a one-minute swimming distance (approximately 30 m) between them, using mask, snorkel and fins. Circle samples covering an area of 12.6 m^2 were laid. This was done by means of a 2-m line attached to a weight, which functioned respectively as radius and center of the circle. First the depth at the center of each circle sample was measured with a measuring tape and the time of each depth measurement was recorded on a plastic board, like all measurements. Within the circle samples the number of urchins of the species Echinothrix diadema were counted and the substrate cover was estimated. The topographic complexity of the reef was estimated using the rugosity measurement method (McClanahan T.R. - Shafir 1990).

Cetacean sightings along the central Catalan coast made during surveys of the Associació Cetàcea

Dades d'albiraments de diferents espècies de cetacis realitzades per l'Associació Cetàcea durant les sortides realitzades en el marc del Projecte Rorqual a la regió central de la costa catalana, Mediterrani occidental, iniciades la primavera de 2013.
Iniciat el març de 2013, el Projecte Rorqual pretén ampliar els coneixements sobre el rorqual comú (Balaenoptera physalus) al mar Mediterrani.
Durant les sortides, es prenen dades geogràfiques, ambientals, biològiques, comportamentals i poblacionals de tots els albiraments de cetacis que es realitzin. Amb elles es vol dur a terme una avaluaciùo de la població de rorquals del Mediterrani occidental, així com d'altres espècies cetàcies.
L'àrea d’estudi es localitza a la costa del davant de les comarques del Baix Llobregat, el Garraf i el Baix Penedès, en la zona situada entre les poblacions de Castelldefels i Segur de Calafell i a una distància d’entre 5 i 12 milles de la costa, arribant fins a la isòbata dels 1.000 metres de profunditat.
Aquesta elecció no és atzarosa, respon a l’existència d’albiraments documentat de rorquals comuns durant els últims anys en la zona esmentada, la qual cosa fa pensar que les aigües del mar catalanobalear podrien ser una zona de pas entre les àrees d’hivernació (probablement situades en la part sud del Mediterrani) i les àrees d’alimentació estivals, principalment la situada al mar de Ligúria.
