High-resolution underway measurements of surface water pH, CO2 fugacity (fCO2), and total dissolved inorganic carbon (DIC), along with discrete bottle sample analyses from depths, were obtained in July 2005 and September 2006 in the Mississippi River Plume (MRP) and the Orinoco River Plume (MRP). The resulting data were analyzed to compare and contrast the CO2 fluxes and carbonate system behavi...

abstract ground water flow and skin is the most important phenomenon in the process streams are involved not only in the face of the whole earth, but also of the life of man on earth can. degradation of coastal erosion, lateral stability and continuity in iran and around the world each year destroys fertilized agricultural lands around the river, coastal installations, bridges, and is general h...

Conventionally flood mapping typically includes only a static water level (e.g. peak of a storm tide) in coastal flood inundation events. Additional factors become increasingly important when increased water-level thresholds are met during the combination of a storm tide and increased mean sea level. This research incorporates factors such as wave overtopping and river flow in a range of flood ...

PURPOSE To describe the fatty acid composition of human colostrum in three different regions of China. METHODS Women were recruited from river/lake, coastal and inland regions of China during late pregnancy. Their diet frequency was assessed during the 34th week of pregnancy. Colostrum samples were collected between postpartum days 3 and 5. Thirty-one different fatty acids were separated and ...

—Until recently, coastal cutthroat trout Oncorhynchus clarkii clarkii were thought to use estuaries primarily as a migration corridor to and from the ocean, rather than as a rearing environment. However, recent research in Oregon’s Salmon River estuary has defined an extensive estuarine life history for a portion of the population. This study was designed to assess the diet of coastal cutthroat...

Lichen-forming fungi can occur on river and lake margins subjected to varying water levels, and on tidal coastal rocks where they can constitute major components of the biota. There are approximately 700 species known from coastal rocks and 200 from freshwater river and lake margins. Most cannot survive constant immersion although there are exceptions. Some species are only exposed at the lowes...

Rainbow trout native to the McCloud River, California, USA (Oncorhynchus mykiss stonei) are thought to represent a relic, nonanadromous trout adapted to harsh, fragmented environments. These fish, commonly named McCloud River 'redband' trout, survive in their most primitive form in a small, spring-fed stream, Sheepheaven Creek, in the upper McCloud River drainage. Turn-of-the-century fisheries ...

We used more than thirty years of water quality monitoring data collected by the United States Geological Survey at several stations in the Altamaha River and its tributaries to examine the relationship between population density, agricultural land use, and nutrient export from the watershed. Population densities in the Altamaha River watershed increased during the study period, most notably in...

The structural features of humic acid (HA) at the sediment surface of the tideland at the Hayatsuegawa-river mouth at the Ariake Sea were investigated for the utilization of HA toward an environmental indicator of the features of the river basin and coastal region. 1H NMR analysis revealed a high-content hydrocarbon residue with a similar type of terrigenous HA. Direct and methylation-pyrolysis...
