Deposition, benthic residence, and resuspension of fine organic particles in a mountain stream
Deposition benthic residence resuspension fine organic particles mountain stream
2014/5/13
We estimated deposition and resuspension rates of natural particulate organic matter (POM) in Bloomington Creek, Idaho, a mountain stream flowing at 225 L s-1. POM was collected from the water column,...
Large submarine groundwater discharge and benthic eutrophication in Bangdu Bay on volcanic Jeju Island, Korea
Large submarine groundwater discharge benthic eutrophication Bangdu Bay volcanic Jeju Island Korea
2014/5/13
We estimated the submarine discharge of groundwater (SGD) and associated nutrients into the semienclosed Bangdu Bay on a volcanic island, Jeju, Korea, by analyzing 222Rn, Ra isotopes (224Ra and 226Ra)...
Effects of warming on benthic communities in a boreal lake: Implications of climate change
Effects of warming benthic communities boreal lake: Implications climate change
2014/5/13
We experimentally warmed a series of shallow enclosures by 4.5°C and measured responses of the epilithon (biofilm on rocky surfaces) and invertebrates. Maximum rates of net photosynthesis increased by...
The effects of cultural eutrophication on the coupling between pelagic primary producers and benthic consumers
The effects of cultural eutrophication coupling pelagic primary producers benthic consumers
2014/5/13
We investigated the effects of cultural eutrophication on the coupling between pelagic primary producers and benthic consumers in Lake Tahoe. Spatial and temporal changes in zoobenthos energetics were...
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...
Pore-water advection and solute fluxes in permeable marine sediments (I): Calibration and performance of the novel benthic chamber system Sandy
Pore-water advection marine sediments Calibration and performance benthic chamber system Sandy
2014/5/9
This contribution introduces the benthic chamber system Sandy that was developed for studying in situ solute fluxes in permeable sandy sediments where advective pore-water transport can dominate solut...
Pore-water advection and solute fluxes in permeable marine sediments (II): Benthic respiration at three sandy sites with different permeabilities (German Bight, North Sea)
Pore-water advection solute fluxes permeable marine sediments Benthic respiration three sandy sites different permeabilities
2014/5/9
This contribution presents total oxygen uptake (TOU) rates and nutrient fluxes of organically poor permeable shelf sands of the German Bight. Measurements have been made in situ with the novel autonom...
Benthic metabolism and nitrogen cycling in a subtropical east Australian estuary (Brunswick): Temporal variability and controlling factors
Benthic metabolism nitrogen cycling subtropical east Australian estuary Temporal variability controlling factors
2014/5/8
We examined temporal variability in benthic metabolism and nitrogen (N) cycling in the subtropical Brunswick Estuary, Australia from December 2000 to December 2002. Benthic metabolism was tightly coup...
Species-specific ingestion of organic carbon by deep-sea benthic foraminifera and meiobenthos: In situ tracer experiments
Species-specific ingestion organic carbon deep-sea benthic foraminifera meiobenthos situ tracer experiments
2014/5/8
We measured organic carbon uptake rates by deep-sea benthic foraminifera and studied differences among species, living depth, and seasons to investigate how these protists contribute to carbon consump...
The Benthic Algal Flora of Demirdöven Dam Reservoir (Erzurum, Turkey)
Algae epipelic epilithic seasonal variations reservoir Turkey
2010/3/19
Seasonal variations in the species composition of the benthic algae of Demirdöven Dam Reservoir were investigated in 2000 and 2001. The benthic algal flora consisted of 174 taxa belonging to the ...
