potential capability of heterotrophic bacteria for extracellular enzyme synthesis and their activity were determined in a transect from dunes to a water depth of 1 m in a sandy beach near sopot on the southern Baltic coast. Among studied enzymes, alkaline phosphatase, esterase lipase, and leucine arylaminase were synthesized in a higher degree, whereas α-fucosidase, β­glucouronidase and α-galac...

Eighteen sandy beaches were sampled along the 1659 km of the Galician coast (NW Spain) six months after the Prestige oil-spill to study the impact of the fuel and the clean-up activities on the macroinfauna community. A transect was extended at each beach, from above the drift line to below the swash line at five sampled levels; at each level six 0.05 m2 replicates were taken to a depth of 30 c...

A field experiment was performed offshore Cassino Beach, Southern Brazil. In this area mud deposits were observed, mainly originated from the Patos Lagoon. Episodically, and associated with storm waves able to transport the mud from offshore to the beach, the usual sandy beach is covered by mud. This is a unique process along the Brazilian coastline, and the field experiment aimed to record the...

Thoracophelia (Annelida, Opheliidae) are burrowing deposit feeders generally found in the mid- to upper intertidal areas of sandy beaches. Thoracophelia mucronata (Treadwell, 1914) is found along the west coast of North America, including at Dillon Beach, CA. Two additional species, Thoracophelia dillonensis (Hartman, 1938) and T. williamsi (Hartman, 1938) were also described from this beach. T...

The sandy barrier islands of Cape Hatteras National Seashore, USA, attract large seasonal influxes of tourists, and are host to numerous motels, rentals and second homes. To investigate the impacts of nearby urbanization on public trust waters, sampling was conducted in nine brackish water bodies within this coastal national park. A large tidal urban ditch delivered runoff-driven fecal-contamin...

Litter categories and grades of Welsh beaches were satisfactorily predicted by multi-layered feed forward neural networks and fuzzy systems, which are artificial intelligence techniques. Neural network structures with hidden layers consisting of 40 neurons of uni-bipolar sigmoid functions were constructed for Welsh beaches and they were trained by supervised (conjugate gradient) learning algori...

Long-term observational datasets that record and quantify variability, changes and trends in beach morphology at sandy coastlines together with the accompanying wave climate are rare. A monthly beach profile survey program commenced in April 1976 at Narrabeen located on Sydney's Northern Beaches in southeast Australia is one of just a handful of sites worldwide where on-going and uninterrupted ...

Sandy beaches are among the most extensive coastal ecosystems in Brazil and constitute important buffer zones between terrestrial marine environments. The present study aimed to analyze distribution spatiotemporal variation of meiofaunal community an urban tropical sandy beach northeastern with a particular focus on nematofauna. We set up 4 transects during 2 sampling periods evaluate different...

The Dutch energy company Eneco received the concession to construct a 116 MW windfarm on Maasvlakte-2, recent large seaward port extension of Port Rotterdam. land reclamation is protected partly by hard sea defence and soft defence, consisting sandy beach adjacent dunes. Twelve wind turbines with monopile foundation will be constructed beach, close or in waterline. erosive maintained regular fo...
