The Daliao River System (DRS) estuary in the Liaodong Bay has a highly industrial, urbanized, and agricultural
catchment. The objective of this study was to investigate the multi-elemental geochemist...
Allostratigraphic and Sedimentologic Applications of Trace Fossils to the Study of Incised Estuarine Valleys:An Example from the Virgilian Tonganoxie Sandstone Member of Eastern Kansas
Allostratigraphic Sedimentologic Applications Trace Fossils
2009/10/21
The Tonganoxie Sandstone Member (Stranger Formation) records part of the infill of an estuarine valley system that was incised during a late Missourian (Late Carboniferous) drop in sea level and subse...
Sedimentology and Ichnology of Paleozoic Estuarine and Shoreface Reservoirs,Morrow Sandstone,Lower Pennsylvanian of Southwest Kansas,USA
Sedimentology and Ichnology Paleozoic Estuarine Shoreface Reservoirs
2009/10/21
Integration of ichnologic, sedimentologic, and stratigraphic studies of cores from Lower Pennsylvanian oil and gas reservoirs (lower Morrow Sandstone, southwest Kansas) allows researchers to distingui...
Changes in phosphorus biogeochemistry along an estuarine salinity gradient: The iron conveyer belt
Changes in phosphorus biogeochemistry estuarine salinity gradient The iron conveyer belt

We used sequential extractions to quantify different forms of particulate phosphorus (PP) in sediments along the salinity gradient of the Patuxent River estuary. About 50-90% of the PP was phosphate b...
Stable isotopic detection of ammonium and nitrate assimilation by phytoplankton in the Waquoit Bay estuarine system
Stable isotopic detection ammonium and nitrate assimilation phytoplankton Waquoit Bay estuarine system
2014/4/22
We measured concentration and δ15N of chlorophyll a (Chl a), NO3-, and NH4+ along a salinity gradient in Childs River, Massachusetts, in winter, spring, and summer. We used the δ15N of Chl a as a prox...
Experimental Evaluation of Ca-K Exchange Selectivity Reactions in Estuarine Sediments
Experimental Evaluation Ca-K Exchange Selectivity Reactions Estuarine Sediments

Abstract: Clay materials separated from estuarine sediments in Louisiana exhibit a selectivity for exchangeable calcium in laboratory experiments. The studies were conducted at 25°C and 60°C in mixed ...
Clay Distributions in Recent Estuarine Sediments
Clay Distributions Recent Estuarine Sediments
2011/11/18
Abstract: The distribution of clay minerals in Recent sediments can be explained by the relative stability of the clays. The rates of particle aggregation for three clays were determined in the labora...
