Interannual Variation of Bivalve Populations on Temperate Tidal Flats

Tidal Flats and Muddy Seafloors

The objectives of our studies in FY09 are to collect observations of currents, waves, and bathymetry on tidal flats, and to develop, test, and improve models for tidal-flat processes and for mud-induced dissipation of waves in shallow water. Specific goals relating to tidal flats are to: Investigate the relative importance to the circulation of riverine and tidal flows, and Estimate the bottom ...

Ichnological evidence of Megalosaurid Dinosaurs Crossing Middle Jurassic Tidal Flats

A new dinosaur tracksite in the Vale de Meios quarry (Serra de Aire Formation, Bathonian, Portugal)preserves more than 700 theropod tracks. They are organized in at least 80 unidirectional trackways arranged in a bimodal orientation pattern (W/NW and E/SE). Quantitative and qualitative comparisons reveal that the large tridactyl, elongated and asymmetric tracks resemble the typical Late Jurassi...

Detection of Bivalve Beds on Exposed Intertidal Flats Using Polarimetric SAR Indicators

We propose new indicators for bivalve (oyster and mussel) beds on exposed intertidal flats, derived from dual-copolarization (HH + VV) TerraSAR-X, Radarsat-2, and ALOS-2 images of the German North Sea coast. Our analyses are based upon the Kennaugh element framework, and we show that different targets on exposed intertidal flats exhibit different radar backscattering characteristics, which mani...
