Seasonal fluctuation of the meiobenthos community in Avicennia marina mangrove sediments at Gazi Bay (Kenya) between 1992 and 1993

Densities of the most important meiobenthos phyla in an Avicennia marina mangrove sediment in Gazi Bay (Kenya) together with the sediment environmental data. Three replicate samples were taken for every monthly sample between August 1992 and July 1993. The data were digitized by VLIZ from the original report: Okondo, J. (1995). Community structure and seasonal fluctuation of meiobenthos in the Avicenna marina mangrove sediments at Gazi Bay, Kenya. MSc Thesis. RUG: Gent. 56 pp.
Biotic samples were taken using cores of diameter 3.6 cm for meiofaunal analysis.
This was done to a depth of about 20 cm. Soon after sampling the sediment was sectioned
into four slices of 0-2 cm, 2-4 cm, 4-10 cm and 10-r cm.
Fifteen taxa were observed with most of them occurring in relatively low numbers (
Hyperbenthos community in the salt marsh of Saeftinghe in 1990 and 1991

Density and biomass of hyperbenthos species in the salt marsh community of Saeftinghe between March 1990 and October 1991. The data were digitized by VLIZ from the original report: Dankwa, H.R. (1993). Utilization of estuarine salt marshes by postlarval brown shrimp Crangon crangon. MSc Thesis. RUG: Gent. 49 pp.
Monthly samples were collected with a stow net in an intertidal creek in the marsh of Saeftinghe. Fishing lasted a complete tidal cycle and the net was hauled every hour providing in general, three flood samples and four ebb samples. Water height and the current speed were recorded every fifteen minutes. These two variables were used in the estimation of densities and biomasses. Densities and biomasses were estimated for every hour sampled based on the number of animals and the volume of water that passed through the net within that particular period. From these, estimates for each sampling period were made for the whole creek considering the volume of water that passed through the creek over the same period of time. This was done for each flood and ebb sample. Sixty eight species were caught during the study period but only thirty eight were found to occur regularly in the marsh creek.

Vegetation of the tidal channels in Gazi Bay (Kenya) sampled between July and September 1989

List of present/absent vegetation (seagrasses and benthic macroalgae) and their coverage of the sublittoral zone in Gazi Bay (Kenya) sampled between 24th July and 2nd September 1989. The data were digitized by VLIZ from the original report: De Pauw, K. (1990). De vegetatie van de getijdengeul van Gazi Bay (Kenia); The vegetation of the tidal channels of Gazi Bay (Kenya). MSc Thesis. Rijksuniversiteit Gent. Faculteit Wetenschappen: Ghent. 142 pp.
Thirteen transects were made perpendicularly on the direction of the tidal flow, from the field laboratory down to the lagoon. We also investigated a side channel, which showed a great variety of species, as well as an upstream section of the main channel. The seagrasses were quantified by estimating the degree of coverage (in %) whereas for the algae only presence or absence were noted. In each case the type of substratum has been taken into account (hard or loose). To be able to specify the current velocity, sediment samples were taken all along the transects, in order to determine their particle size. The field work took place in July and August 1989 and was carried out scuba-diving.

Metabolisme, reproductie en vervelling als eindpunten voor het bestuderen van endocriene verstoring bij Neomysis integer in het Schelde-estuarium

Deze dataset resulteert uit een studie naar ecotoxicologische evaluatie van de effecten van hormoonontregelende stoffen die voorkomen in het Schelde estuarium op de endogene mysidaceeën populatie.
De data resulteerd uit een aantal labo testen. Om de mogelijke effecten van de polluenten op mysidaceeën te evalueren worden acute en chronische testen opgezet in het laboratorium. Er worden acute toxiciteittesten opgezet met de geselecteerde stoffen volgens het protocol beschreven door Heijerick et al. (1994). Als biomerkers om de hormoonverstorende werking op mysidaceeën te evalueren worden het energiemetabolisme, het steroïdmetabolisme en specifieke gen -en eiwitexpressie gebruikt. Om effecten op middellange termijn te evalueren worden juveniele mysidaceeën blootgesteld tot ze sexueel gedifferentieerd zijn. Naast de biomerkers voor hormoonverstoring, worden eveneens de groei, vervelling en populatieparameters opgevolgd (e.g. sex-ratio, mortaliteit,). Deze parameters laten toe interferentie van de geteste stof met de groeiregulatie, het ecdysteroïdmetabolisme of de sexuële differentiatie te evalueren.  Mysidaceeën zullen eveneens worden blootgesteld in een multigeneratie-experiment over 2 generaties (tot de eerste generatie juvenielen opnieuw juvenielen voortbrengen) om de effecten van de hormoonverstoorder op lange termijn in te schatten.  Dezelfde eindpunten als in de kortere experimenten worden opgemeten, evenals een aantal reproductieve eindpunten.  Deze eindpunten laten toe een voorspelling te doen van de effecten van de hormoonverstoorder op de overleving van de populatie op de lange termijn.
Characterization of sound scattering layers in the Bay of Biscay using broadband acoustics, nets and video acoustics and biological data

Sound scattering layers (SSLs) are observed over a broad range of spatio-temporal scales and geographical areas. SSLs represent a large biomass, likely involved in the biological carbon pump and the structure of marine trophic webs. Yet, the taxonomic composition remains largely unknown for many SSLs.
To investigate the challenges of SSL sampling, we performed a survey in a small study area in the Northern Bay of Biscay (France) by combining broadband and narrowband acoustics, net sampling, imagery and video recordings. In order to identify organisms contributing to the observed SSLs, we compared measured frequency spectra to forward predicted spectra derived from biological data. This dataset comprises the echo-integrated broadband acoustic data (in Sv(f)), the nets position and depth, and the abundance and the size of the catched organisms acquired during a specific operation of SSLs sampling during (Blanluet et al.)-[https://doi.org/10.1371/journal.pone.0223618].

Loggerhead satellite tracking data from Rethymno, Crete, Greece

During the 2010 and 2011 nesting seasons in Rethymno, Crete, Greece, 21 satellite tags were deployed on post-reproductive loggerhead turtles, 20 females and 1 male. One tag failed, while the remaining 20 transmitted data during the migration period, with most tags continuing to transmit after the individual had reached a site of residency. The female turtles exhibited three distinct strategies, either migrating north into the Aegean Sea, southwest towards the Libyan or Tunisian coasts or remaining resident within the waters of Crete. Females migrated after completing nesting for the season starting in early July. The male turtle exhibited a different behavior migrating away from the nesting beach in mid-June and traveling into the Western Mediterranean basin.
