Seasonal and spatial distribution of particulate organic matter (POM) in the Chukchi and Beaufort Seas
As part of the Western Arctic Shelf–Basin Interactions (SBI) project, the production and fate of organic carbon and nitrogen from the Chukchi and Beaufort Sea shelves were investigated during spring (5 May–15 June) and summer (15 July–25 August) cruises in 2002. Seasonal observations of suspended particulate organic carbon (POC) and nitrogen (PON) and large-particle (453mm) size class suggest t...
متن کاملBuffer capacity andCuaffinity of soil particulate organic matter (POM) size fractions
Particulate organic matter fractions (POM), defined as sand-sized organic separates in soils, are known to be labile organic components with a rapid turnover. Recently, POM fractions were identified to be metalenriched in both metal-contaminated and uncontaminated soils. However, mechanisms for such metalenrichment are poorly understood, because of the paucity of information on the chemical pro...
متن کاملOrganic , elemental and inorganic carbon in particulate matter of six urban environments in Europe
A series of 7-week sampling campaigns were conducted in urban background sites of six European cities as follows: Duisburg (autumn), Prague (winter), Amsterdam (winter), Helsinki (spring), Barcelona (spring) and Athens (summer). The campaigns were scheduled to include seasons of local public health concern due to high particulate concentrations or findings in previously conducted epidemiologica...
متن کاملEmission rates of particulate matter and elemental and organic carbon from in-use diesel engines.
Elemental carbon (EC), organic carbon (OC), and particulate matter (PM) emission rates are reported for a number of heavy heavy-duty diesel trucks (HHDDTs) and back-up generators (BUGs) operating under real-world conditions. Emission rates were determined using a unique mobile emissions laboratory (MEL) equipped with a total capture full-scale dilution tunnel connected directly to the diesel en...
متن کاملTransport and diagenesis of dissolved and particulate terrigenous organic matter in the North Pacific Ocean
Lignin measurements were made on suspended particulate organic matter (POM), total dissolved organic matter (DOM), high-molecular-weight (HMW) DOM, and low-molecular-weight (LMW) DOM in the North Pacific at Station Aloha. Carbon-normalized yields of lignin and dC measurements indicate that while terrigenous organic matter accounts only for B1% of DOM in seawater, submicron POM has a substantial...
