Significant contribution passively sinking copepods downward export flux Arctic waters
2014/4/17
Typically, all undecomposed metazoans found in formalin-poisoned cups of sediment traps are considered to be active intruders (or ‘‘swimmers’’) and are removed to prevent an overestimation of the down...
Modeling vertical excursions of the redox boundary in sediments: Application to deep basins of the Arctic Ocean
Modeling vertical excursions redox boundary in sediments deep basins of the Arctic Ocean
2014/5/4
A diagenetic reaction-transport model was used to simulate how the sediment redox boundary migrates in response to persistent or episodic changes in the deposition flux of degradable organic matter an...
Stable isotope signatures of benthic invertebrates in arctic lakes indicate limited coupling to pelagic production
Stable isotope signatures benthic invertebrates
2014/4/23
We tested the hypotheses that benthic macroinvertebrates, especially chironomid larvae in the Tribe Chironomini,
from small oligotrophic arctic lakes are only weakly linked to pelagic food sources, a...

2014/5/14
To trace the fate of terrigenous dissolved organic nitrogen (DON) in the Arctic Ocean, principal-components
analyses (PCA) was used on a data set of 13 amino acids released via hydrolyses from a tota...
