Problem statement: For a number of geological reasons a proportion of the present coastal plains in the Malay Peninsula were inundated by seawater in the past when pyrite in some of the soils is believed to have been mineralized. Random survey of these sites showed a unique distribution and depth of pyritic layer in the soils along the coastal plains. A study was conducted in order to explain t...

Coastal salt marshes are a buffer between the uplands and adjacent coastal waters in New England (USA). With increasing N loads from developed watersheds, salt marshes could play an important role in the water quality maintenance of coastal waters. In this study we examined seasonal relationships between denitrification enzyme activity (DEA) in salt marshes of Narragansett Bay, Rhode Island, an...

Both Moderate Resolution Imaging Spectroradiometer (MODIS) and Spinning Enhanced Visible and InfraRed Imager (SEVIRI) satellite observations suggest that the narrow heterogeneous Red Sea coastal region is a frequent source of airborne dust that, because of its proximity, directly affects the Red Sea and coastal urban centers. The potential of soils to be suspended as airborne mineral dust depen...

This paper presents a dominant height and basal area response function for juvenile (ages 2-8) loblolly pine stands that have been fertilized with a combination dose of 200 lbs/ac of nitrogen and 50 lbs/ac of phosphorus. The data used to construct the response functions originated from the Region-wide 2 Study of the North Carolina State University Forest Nutrition Cooperative. The data set incl...

Hochiminh City environs have more than 45,000 ha of coastal plain soils which to be continued to the South by the great mangrove forest in Camau peninsula. How to protect and afforest mangroves successfully on these soils when using them also for aquaculture (shrimp, fish, crab, mollusc, etc.)? An answer to this question is now urgently needed. Dealing with the study on soil genesis/ geography ...

Deposition of sea salts is commonly elevated along the coast relative to inland areas, yet little is known about the effects on terrestrial ecosystem biogeochemistry. We examined the influence of NaCl concentrations on N, C, and P leaching from a coastal Oregon forest Andisol in two laboratory studies: a rapid batch extraction (approximately 1 d) and a month-long incubation using microlysimeter...

Using box-counting and spatial regression, this paper analyzes the morphological characteristics of coastal settlement patterns and their spatial determinants, with a case of the Wen-Tai region on the Chinese eastern coast. Coastal settlement patterns, which reflect the interactions between people and the surrounding environment, can indicate the anthropogenic pressure sustained in the coastal ...

Freshwater coastal prairie wetlands once covered large expanses of the Houston-Galveston landscape. A complex wetland matrix of mima mounds and low wetland basins known as prairie potholes provided important ecological services including habitat, lood control and water cleansing. Many of these areas were land leveled for agricultural and development purposes, erasing these features from the coa...
