Archaeological and geomorphological features, as well traces left by tsunamis, earthquakes, vertical earth-crust displacements, are used to identify sea-level coastal changes. Such features may be displaced, submerged or eroded natural processes human activities. Thus, identifying ancient sea levels changes associated with such controversial often leads misinterpretations. We exemplify the use ...

Biogenic reefs are important for habitat provision and coastal protection. Long-term datasets on the distribution and abundance of Sabellaria alveolata (L.) are available from Britain. The aim of this study was to combine historical records and contemporary data to (1) describe spatiotemporal variation in winter temperatures, (2) document short-term and long-term changes in the distribution and...

Using multi-temporal European Remote-sensing Satellites (ERS-1/-2) and Canadian Radar Satellite (RADARSAT-1) synthetic aperture radar (SAR) data over the Louisiana coastal zone, we characterize seasonal variations of radar backscattering according to vegetation type. Our main findings are as follows. First, ERS-1/-2 and RADARSAT-1 require careful radiometric calibration to perform multi-tempora...
