Isotopic and elemental characterization of colloidal organic matter from the Chesapeake Bay and Galveston Bay
(, 1997 Dec)
In order to investigate sources and turnover rates of dissolved organic matter from Chesapeake Bay and Galveston Bay, colloidal organic matter (COM) was isolated using cross-flow ultrafiltration and subsequently characterized ...
Trace metal composition of colloidal organic material in marine environments
(, 2000 Jun)
Marine colloidal material (1 kDa-0.2 mu m) was isolated by cross-flow ultrafiltration followed by diafiltration and freeze-drying from surface waters of the Gulf of Mexico and the Middle Atlantic Eight (MAB), as well as ...
Th-234 scavenging and its relationship to acid polysaccharide abundance in the Gulf of Mexico
(, 2002 May)
Size-fractionated particulate Th-234 and acid polysaccharides (APS) were collected from stations along a transect in the Gulf of Mexico, in order to examine the role of APS content in controlling the extent and rates of ...
Nitrogen and carbon isotopic composition of high-molecular-weight dissolved organic matter in marine environments
High-molecular-weight (HMW) dissolved organic matter (DOM) was isolated using cross-flow ultrafiltration from seawater across a salinity gradient in 2 estuarine/coastal marine environments-Chesapeake Bay/Middle Atlantic ...
Fibrillar polysaccharides in marine macromolecular organic matter as imaged by atomic force microscopy and transmission electron microscopy
(, 1998 Jul)
A consensus is now emerging that the structure of organic macromolecules will determine their function in aquatic systems. Transmission electron microscopy (TEM) is a widely used technique to study the morphology of ...
