Estimation of methanogenesis by quantification of coenzyme F430 in marine sediments
methane hydrate methanogens function-specific compound analysis marine sedimen
2017/4/10
Coenzyme F430 is the hydrocorphinoid nickel complex which acts as active site in methyl-coenzyme M reductase
(MCR). The MCR-F430 complex catalyzes the last step of methanogenesis: reduction of methyl...
Simultaneous quantification of aquatic ecosystem metabolism and reaeration using a Bayesian statistical model of oxygen dynamics
aquatic ecosystem metabolism reaeration Bayesian statistical model oxygen dynamics
2014/4/17
We present a Bayesian statistical model of diel oxygen dynamics in aquatic ecosystems to simultaneously estimate gross primary production, ecosystem respiration, and oxygen exchange with the atmospher...
Quantification of point-source groundwater discharges to the ocean from the shoreline of the Big Island, Hawaii
Quantification of point-source groundwater discharges the ocean shoreline of the Big Island Hawaii
2014/4/18
Aerial thermal infrared imaging has revealed that submarine groundwater discharge (SGD) along the western coast of the Big Island of Hawaii is often focused as point-source discharges that create buoy...

Aerial thermal infrared imaging has revealed that submarine groundwater discharge (SGD) along the western
coast of the Big Island of Hawaii is often focused as point-source discharges that create buo...
Quantification of zooplankton trophic position in the North Pacific Subtropical Gyre using stable nitrogen isotopes
zooplankton trophic position North Pacific Subtropical Gyre
2014/4/17
We quantify the trophic positions of subtropical open-ocean zooplankton species using amino acid–specific
(AA) stable nitrogen isotopic compositions. We model animal trophic position by computing tro...
Molecular quantification of differential ingestion and particle trapping rates by the appendicularian Oikopleura dioica as a function of prey size and shape
Molecular quantification of differential ingestion particle trapping rates the appendicularian Oikopleura dioica function of prey size and shape
2014/4/22
To investigate whether particles are ingested or merely trapped in the house of the appendicularian Oikopleura dioica, we developed a real-time quantitative polymerase chain reaction (qPCR) assay and ...
Quantification of macrobenthic effects on diagenesis using a multicomponent inverse model in salt marsh sediments
Quantification of macrobenthic effects diagenesis using multicomponent inverse model salt marsh sediments
2014/5/19
Using a multicomponent inverse model, we quantified the rates of organic matter (OM) remineralization and the relative importance of major terminal electron acceptors [Fe(III)-(oxy)hydroxides and SO4-...
Quantification of marine snow fragmentation by swimming euphausiids
marine snow fragmentation swimming euphausiids
2014/5/19
Sinking of marine snow is a major mechanism of particulate carbon transport from surface waters to the seafloor. Any process altering the abundance or size of marine snow influences carbon flux and fo...
Methane bubbles in Lake Kinneret: Quantification and temporal and spatial heterogeneity
Methane bubbles Lake Kinneret Quantification temporal and spatial heterogeneity
2014/5/20
The amount of methane bubbles rising from the bottom of Lake Kinneret was quantified by using a dual-beam echo sounder. Both echo-counting (EC) and echo integration (EI) techniques were implemented. B...
Quantification, base composition, and fate of extracellular DNA in marine sediments
Quantification, base composition fate of extracellular DNA marine sediments
2014/5/27
The discovery of high concentrations of DNA in marine sediments unaccounted for by living biomass suggests the presence of a large fraction of extracellular DNA, which might play an important role in ...
