Wetland-driven shifts in suspended particulate organic matter composition of the Hudson River estuary, New York
Wetland-driven shifts suspended particulate organic matter composition Hudson River estuary New York
2014/4/17
Elemental carbon and nitrogen, stable isotopes, and lignin phenols were quantified for suspended particulate material exchanging between Tivoli Bays wetlands and the main stem of the freshwater-tidal ...
Characterization of particulate organic matter in the water column of the South China Sea using a shotgun proteomic approach
Characterization of particulate organic matter water column of the South China Sea shotgun proteomic approach
2014/4/17
We characterized particulate organic matter (POM) collected from both the surface (41 m and 200 m) and mesopelagic layers (500 m and 1000 m) in the western South China Sea. By using a shotgun proteomi...
Tillage Effects on Spatiotemporal Variability of Particulate Organic Matter
Tillage Effects Spatiotemporal Variability Particulate Organic Matter
2009/12/2
This study was performed to evaluate effects of no-till (NT) and standard tillage (ST) on POM in two 15-ha neighboring fields from 2003 to 2004. We also evaluated the effects of minimum tillage (MT) o...

Seasonally varying nitrogen isotope particulate organic matter
2014/4/17
Large temporal variations in the nitrogen isotopic composition (d15N) of particulate organic matter (POM)
and dissolved inorganic nitrogen (DIN) species in Lake Kinneret occurred in response to seaso...
Evidence of prokaryotic metabolism on suspended particulate organic matter in the dark waters of the subtropical North Atlantic
prokaryotic metabolism particulate organic matter
2014/4/17
The distribution of prokaryotic abundance (PA), respiratory activity (ETS), heterotrophic production (PHP),
and suspended particulate (POM) and dissolved (DOM) organic matter was determined in the me...
D/H ratios of fatty acids from marine particulate organic matter in the California Borderland Basins
fatty acid particulate organic matte California Borderland Basins
2014/4/8
We report the molecular and hydrogen–isotopic compositions of fatty acids extracted from suspended particulate
organic matter (POM) and surface sediments at three stations off the southern Cali...
On the treatment of particulate organic matter sinking in large-scale models of marine biogeochemical cycles
treatment particulate organic matter large-scale models marine biogeochemical cycles
2010/1/15
Various functions have been suggested and applied to represent the sedimentation and remineralisation of particulate organic matter (POM) in numerical ocean models. Here we investigate some representa...
Dissolved and particulate organic matter source-age characterization in the upper and lower Chesapeake Bay: A combined isotope and biochemical approach
Dissolved and particulate organic matter source-age characterization the upper and lower Chesapeake Bay A combined isotope and biochemical approach
2014/5/4
In order to characterize the sources and ages of organic matter contributing to river and estuarine outflow waters, the present study investigated Δ14C and δ13C signatures of the major operationally d...
Wave tank study of particulate organic matter degradation in permeable sediments
Wave tank permeable sediments
2014/5/4
We used a wave tank to study the influence of pore-water flow and diffusive transport on the degradation of labile particular organic matter (POM: Ulva lactuca pieces) embedded in permeable sediment. ...
Irradiation of particulate organic matter (POM) at light intensities found at the earth’s surface should induce reduction in molecular weight, as found for dissolved organic matter, and hence res...
Primary consumers and particulate organic matter: Isotopic evidence of strong selectivity in the estuarine transition zone
Primary consumers particulate organic matter
2014/5/19
The freshwater–saltwater transition zones of upper estuaries often contain high concentrations of particulate
organic matter (POM) that could potentially support their productive food webs. Our objec...
The influence of filter-feeding benthic macroinvertebrates on the transport and deposition of particulate organic matter and diatoms in two streams
