Role of sulfate reduction and methane production by organic carbon degradation in eutrophic fjord sediments (Limfjorden, Denmark)
Role of sulfate reduction methane production organic carbon degradation eutrophic fjord sediments
2014/4/17
The anaerobic mineralization of buried organic matter through sulfate reduction and methanogenesis was studied in 2-m-long piston cores of organic-rich, silty-clay sediment from two sites in Limfjorde...
Composition and degradation of marine particles with different settling velocities in the northwestern Mediterranean Sea
Composition degradation marine particles different settling velocities northwestern Mediterranean Sea
2014/4/22
Settling particles were collected from the Ligurian Sea in the northwestern Mediterranean Sea in May 2003 and separated by elutriation into different settling velocity classes (>230, 115-230, 58-115, ...
Degradation of water quality in Lough Neagh, Northern Ireland, by diffuse nitrogen flux from a phosphorus-rich catchment
Degradation of water quality Lough Neagh Northern Ireland diffuse nitrogen flux phosphorus-rich catchment
2014/4/22
Annually resolved fossil records of nitrogen (N) inputs (as sedimentary δ15N, N content), aquatic production (δ13C, C content), and algal abundance and gross community composition (pigments, nonsilice...
Tracing the production and degradation of autochthonous fractions of dissolved organic matter using fluorescence analysis
Tracing the production degradation of autochthonous fractions dissolved organic matter fluorescence analysis
2014/5/13
We present the results of a mesocosm experiment investigating the production and utilization of autochthonous dissolved organic matter (DOM) by the plankton community under different inorganic nutrien...
Benthic life in the pelagic: Aggregate encounter and degradation rates by pelagic harpacticoid copepods
Benthic life in the pelagic Aggregate encounter degradation rates pelagic harpacticoid copepods
2014/5/9
We measured field abundances, feeding rates, swimming behavior, and particle colonization of two harpacticoids, the pelagic Microsetella norvegica and the semibenthic , to examine (1) if aggregates ha...
New organic matter degradation proxies: Valid in lake systems?
New organic matter degradation proxies Valid in lake systems
2014/5/19
We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameter...
Microbial degradation of peptidoglycan in seawater
Microbial degradation peptidoglycan seawater
2014/5/20
A constituent of the bacterial cell wall, peptidoglycan, has been suggested to be a significant fraction of marine dissolved organic matter, but little is known about its turnover. We measured hydroly...
