Seasonally varying nitrogen isotope biogeochemistry of particulate organic matter in Lake Kinneret, Israel
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...
Deposition of nitrogen and phosphorus on the Baltic Sea:seasonal patterns and nitrogen isotope composition
nitrogen phosphorus Baltic Sea seasonal patterns nitrogen isotope composition
2010/1/18
Atmospheric deposition of nitrogen and phosphorus on the central Baltic Sea (Baltic Proper) was estimated monthly at two coastal stations and two isolated islands in 2001 and 2002. Yearly nitrogen dep...
High-resolution profiles and nitrogen isotope tracing reveal a dominant source of nitrous oxide and multiple pathways of nitrogen gas formation in the central Arabian Sea
High-resolution profiles nitrogen isotope tracing reveal dominant source of nitrous oxide multiple pathways nitrogen gas formation in the central Arabian Sea
2014/4/22
The oxygen minimum zone (OMZ) of the Arabian Sea is a significant source of nitrous oxide (N2O), yet the metabolism responsible for N2O production is unclear. High-resolution profiles identified peaks...
Interannual variation in stable carbon and nitrogen isotope biogeochemistry of the Mattaponi River, Virginia
Interannual variation stable carbon nitrogen isotope biogeochemistry Mattaponi River Virginia
2014/5/5
Seasonal and interannual variation of the stable carbon (C) and nitrogen (N) isotope composition of suspended particulate organic matter (POM) was measured in the brackish and tidal freshwater regions...
The effect of water velocity on stable carbon and nitrogen isotope signatures of periphyton
water velocity stable carbon nitrogen isotope signatures
2014/5/22
Water movement affects carbon and nitrogen isotopic signatures of algae, possibly through effects on boundarylayer thickness. We describe a laboratory experiment carried out in artificial streams, whi...
Relationship of nitrogen isotope fractionation to phytoplankton size and iron availability during the Southern Ocean Iron RElease Experiment (SOIREE)
