Concentrations of phytoplankton, chlorophyll, POC, dry weight measurements and abiotic data in the surface water of Gazi creek (Kenya) sampled in August 1989

Data on concentrations of chlorophyll, phytoplankton, POC and dry weight measurements during three 24h-cycli at Gazi Creek in August 1989. Additionally tide, temperature, salinity and pH were measured. The data were digitized by VLIZ from the original report: Aernaudts, H. (1990). Seston in mangrove ecosysteem (Gazi, Kenia) = Seston in a mangrove ecosystem (Gazi, Kenya). MSc Thesis. VUB: Brussel. 52 pp.
During the month of August 1989, three 24 cycli were conducted in the Gazi creek, Kenya. Every 4 hours, seston samples (10L of surface water) were taken at the banks of the creek. The samples were analysed for chlorophyl, POC, dry weight and phytoplankton concentrations. The samples for primary production were in-situ incubated. It was generally observed that the litoral-benthic phytoplankton species were dominant in the phytoplankton composition. The pelagic diatoms and the freshwater species Scenedesmus sp. were continuously present in an almost constant low concentration. The concentration in chlorofyl a, POC, dry weight and phytoplankton decreased with increasing water levels. At the sampling location, the ratio chlorophyl a/dry weight and the comparison between chlorophyll a - primary production and phytoplankton concentration demonstrated a limited interaction at the contact area between the creek and the mangroves.
Epifauna community at Waarde and Saeftinghe (Westerschelde) in 1991

The data were digitized by VLIZ from the original report: Makwaia, E.S. (1992). Utilization of saltmarshes by fishes and macrocrustaceans in the Westerschelde estuary. MSc Thesis. RUG: Gent. 49 pp.
Samples were collected in February, April, June and August in the saltmarsh of Waarde. In the saltmarsh of Saeftinghe samples were collected in April, June and August. A passive fishing method was used to sample the organisms migrating in and out of the creeks. The gear used was a simple fykenet that was operated from a bridge across the saltmarsh creek. When water started to enter the creek on the rising tide, the net was placed on the creek bottom, its mouth facing the current. Ropes and weights kept the net in place and the net was hauled every hour. After the moment of high water the net was placed at the other side of the bridge, now facing the ebb current. Measurements of the current and waterheight allowed quantification of the catches in relation to the volume of water which passed through the net. All animals caught were identified to species level, counted and measured under the binocular microscope. The dry weight of the detritus present in all samples was measured and used as an environmental variable. Common species caught included, Neomysis integer, Mesopodopsis slabberi, Crangon crangon, Palaemonetes varians, Corophium volutator, Gammarus salinus, Carcinus maenas, Pomatoschistus microps and Platichthys flesus postlarvae.

World Database of Nematodes

A world checklist of free-living marine Nematodes, compiled by taxonomic experts and based on peer-reviewed literature.
Nematodes constitute one of the most numerous and widespread groups of animals, inhabiting seas, fresh water, soil or living as parasites of animals and plants. Apparently simple organisms, nematodes possess astounding plasticity to adapt to a wide range of conditions and habitats. Nematodes are most widely known as parasites of plants and animals but they are even more numerous as free inhabitants of soil and water. Although nematodes look very similar in general structure, their morphology is very diverse, ranging from cylindrical to aberrant body shapes, which implies different locomotion patterns, while different mouth morphology relates to their feeding ecology.

Nemys offers documentation on free-living marine, brackish, fresh-water and terrestrial nematodes, mainly providing taxonomical information but also ecological information, including literature on type species which can be consulted by the registered users of this online tool.

Nemys is integrated into the World register of Marine Species (WoRMS) hosted at the Flanders Marine Institute (VLIZ), and managed by an international team of taxonomic editors with the help of the WoRMS – Aphia data management team.

Taxonomic Information System for the Belgian coastal area

Taxonomic Information System for the Belgian coastal area. Biogeographical information on (mainly) Belgian species. Focus area of the dataset spans from north of Wimereux (northern France) to the Scheldt estuary (southern Netherlands).
With TISBE, VLIZ tries to develop a comprehensive list of species recorded from the Belgian coast, the Southern Bight of the North Sea and the surrounding countries. The focal area for this database spans from northern France (rocky shores north of Wimereux, where the fauna changes dramatically) to southern Holland, including the Delta area and whole of the tidal part of the Scheldt estuary. Distributions from further away are recorded only if the are listed in publications dealing mainly with distribution records from the focus area. The precision with which the distribution records, both on the geographical and on the temporal scale, are recorded, is variable: the closer a record is to the focal area, the more details we try and record. 

The sources of information are mainly published literature. All distribution records contain a description of the source. Leaving such an 'audit trail' makes it possible to check the validity of every single distribution record by going back to the sources of our information. 

TISBE is build on top of VLIZ's species register, Aphia, and this web application always contains links to taxonomic details, and other taxon-specific information, as they are known in Aphia. From within TISBE, only those species are visible that are known to occur in the area.
Meiobenthos in stations 115bis in het Belgisch deel van de Noordzee (1999)

The abundance, community composition and species diversity of the nematode community at a station on the Belgian Continental Shelf is documented on a monthly basis. This study was carried out as part of a PhD thesis
The response of a nematode community to phytoplankton sedimentation was investigated at an organically enriched station on the Belgian coast, 115 bis. Both structural (abundance, community comosition and species diversity) and functional (trophic composition) aspects of the nematode community were evaluated on a monthly basis. The phytoplankton community was analysed by examining diatoms and Phaeocystis colonies in surface waters. To assess phytoplankton sedimentation, pigment content of the sediment was determined on a regular basis.

SEAPOP NINA

SEAPOP (SEAbird POPulations) is a long-term monitoring and mapping programme for Norwegian seabirds that was established in 2005. The programme represents a new initiative for these activities in Norway, Svalbard and adjacent sea areas, and will provide and maintain base-line knowledge of seabirds for an improved management of this marine environment. The data analyses aim to develop further models of seabird distribution and population dynamics using different environmental parameters, and to explore the degree of covariation across different sites and species. This knowledge is urgently needed to distinguish human influences from those caused by natural variation.

Données des campagnes de Suivi Aérien de la Mégafaune Marine de l’espace maritime métropolitain et de ses zones limitrophes.
L’objectif des survols de l’espace maritime métropolitain et de ses zones limitrophes était de produire un état des lieux de la distribution spatiale et de l'abondance d’espèces de mégafaune (mammifères et oiseaux marins, tortues et élasmobranches principalement). Le jeu de données est composé de deux jeux de données : SAMM1 pour l'hiver 2011 et SAMM2 pour l'été 2012. Ces données ont été collectées dans le cadre du Programme d’Acquisition de Connaissances sur les Oiseaux et les Mammifères Marins (PACOMM) coordonné par l’Agence des Aires Marines Protégées. Ce programme avait pour objectif principal d’améliorer les connaissances nécessaires à l’évaluation et la mise en place du réseau de sites Natura 2000 au-delà de la mer territoriale. Les données ont été collectées par des équipes de scientifiques et des observateurs coordonnées par l’Observatoire PELAGIS et formés spécifiquement au protocole d’observation aérienne mis en place dans le cadre de ce programme. Les campagnes SAMM ont permis de collecter plus de 28 000 données d’observations d’espèces dans les eaux métropolitaines le long de plus de 100.000 km de transect. Ce jeu de données est constitué uniquement des données d’occurrence (espèce, localisation, date et nom du programme) sur les oiseaux et mammifères marins, d’autres espèces (requins, raies, tortues marines, poissons osseux).
