Land hermit crabs are common in many insular and coastal habitats in tropical and subtropical regions worldwide (Hartnoll, 1988; Greenaway, 2003). Some species, such as Coenobita clypeatus (Herbst), may be found many kilometres inland (Chace & Hobbs, 1969; DeWilde, 1973; NievesRivera & Williams, 2003). However, relatively few studies have addressed the densities of land hermit crabs, their ecol...

C hina’s position as the world’s second largest economy is largely due to its rapid economic growth in the coastal region, which composes only 13% of China’s total land area, yet contributes 60% of the gross domestic product (GDP). To create extra land for the rapidly growing economy, coastal wetlands have been enclosed by thousands of kilometers of seawalls, whose length exceeds that of China’...

The current global projections of future sea level rise are the basis for developing inundation hazard maps. However, contributions from spatially variable coastal subsidence have generally not been considered in these projections. We use synthetic aperture radar interferometric measurements and global navigation satellite system data to show subsidence rates of less than 2 mm/year along most o...

The upper coast of Texas has potential for onshore and offshore wind farm installations. Seabirds are important apex predators of estuarine and nearshore marine ecosystems and may be impacted by electricity-generating wind turbines. The area also is a crossroads for trans-Gulf and circum-Gulf of Mexico migrating land birds. Determination of avian density on land is facilitated by laser rangefin...

Land reclamation in coastal areas may have a significant effect on local ground water systems. Steady-state analytic solutions based on Dupuit and Ghyben-Herzberg assumptions are derived to evaluate this effect. Two situations are considered, both with ground water flow resulting from precipitation recharge: the coastal aquifer of an extensive landmass and an island. The results show that after...

The coastal area is a multi-issue area and its observation provides heterogeneous geographical database. Challenges are located on the integration and the rendering of these data: (1) geographic data used to characterize the sea must be combined to obtain water depth and sea/land interface (data heterogeneity problem) and (2) current visualization systems do not provide continuous rendering on ...

The interrannual variability of coastal sea surface temperature (SST) anomalies confined off Senegal is explored from a new viewpoint of the ocean-land-atmosphere interaction. The phenomenon may be classified into "coastal Niño/Niña" in the North Atlantic as discussed recently in the Northeastern Pacific and Southeastern Indian Oceans. The interannual variability of the regional mixed-layer tem...

Increased loads of land-based pollutants are a major threat to coastal-marine ecosystems. Identifying the affected marine areas and the scale of influence on ecosystems is critical to assess the impacts of degraded water quality and to inform planning for catchment management and marine conservation. Studies using remotely-sensed data have contributed to our understanding of the occurrence and ...

The long-term goal of this project is to quantify the environmental drivers of extremely rapid coastal erosion in the Arctic, and to begin developing predictive models of future rates of coastal erosion resulting from climate change. Our study is focused on the Beaufort Sea coast within the National Petroleum Reserve – Alaska (NPR-A), approximately halfway between Barrow and Prudhoe Bay. We are...
