Isotopic heterogeneity and cycling of organic nitrogen in the oligotrophic ocean
Isotopic heterogeneity cycling of organic nitrogen oligotrophic ocean
2014/4/22
We measured the nitrogen (N) isotopic composition (δ15N) of a large set (n = 38) of high-molecular-weight (HMW) dissolved organic nitrogen (DON) samples isolated from the tropical and subtropical Nort...
Remarkable heterogeneity in meso- and bathypelagic bacterioplankton assemblage composition
Remarkable heterogeneity in meso bathypelagic bacterioplankton assemblage composition
2014/5/4
We investigated meso- to bathypelagic (500-3,000 m) bacterioplankton assemblage composition at 19 locations in the North Atlantic Ocean beneath the offshore Amazon River plume, in the North Pacific Oc...
Effect of macrozoobenthos on two-dimensional small-scale heterogeneity of pore water phosphorus concentrations in lake sediments: A laboratory study
Effect of macrozoobenthos two-dimensional small-scale heterogeneity pore water phosphorus concentrations lake sediments A laboratory study
2014/5/9
We used mesocosms equipped with two-dimensional (2D) pore water samplers (24 rows X 24 columns, 9-mm spatial resolution) to resolve and quantify some of the complex spatial patterns in diagenetic reac...
Using the hidden isotopic heterogeneity in phyto- and zooplankton to unmask disparity in trophic carbon transfer
isotopic heterogeneity phyto- and zooplankton trophic carbon transfer
2014/5/22
In this study, we show that natural phototrophic populations can be probed individually for their in situ δ13C signature by linking fluorescence-activated cell sorting and isotope-ratio mass spectrome...
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...
