Transport and mineralization rates in North Sea sandy intertidal sediments, Sylt-Rømø Basin, Waddensea
Transport and mineralization rates North Sea sandy intertidal sediments, Sylt-Rø mø Basin Wadden Sea
2014/5/8
We investigated the rates of the main microbiological processes (primary production, aerobic and anaerobic carbon degradation) and transport phenomena in an intertidal sand plate with a combination of...
A note on the potential transport of scalars and organisms by surface waves
potential transport scalars organisms surface waves
2014/5/19
Wave-induced transport that is not directly reflected in Eulerian current measurements, an effect known as Stokes drift, may play a significant role in the transport of organisms and solutes in the ne...
Limited transport and recolonization potential in shallow tidal estuaries
Limited transport recolonization shallow tidal estuaries
2014/5/14
Evidence of limited larval exchange and high levels of self-recruitment in marine populations continues to accumulate, implying that marine systems are not as open as we once believed. In estuaries, s...
Breathing sediments: The control of diffusive transport across the sediment-water interface by periodic boundary-layer turbulence
Breathing sediments diffusive transport sediment-water interface periodic boundary-layer turbulence
2014/5/22
We performed combined in situ measurements of bottom boundary-layer turbulence and of diffusive oxygen fluxes at the sediment-water interface in a medium-sized mesotrophic lake. The turbulence was dri...
Propagule transport as a key method of dispersal in benthic foraminifera (Protista)
Propagule transport dispersal benthic foraminifera
2014/5/22
The distributional patterns of benthic foraminifera provide key information for paleoclimatic, paleoecologic, and paleoceanographic studies. Yet the dispersal mechanisms that provide a crucial link be...
Planktonic carbon cycling and transport in surface waters of the highly urbanized Hudson River estuary
Planktonic carbon cycling and transport surface waters highly urbanized Hudson River estuary
2014/5/21
We examined variations in organic carbon (OC) pools and microplanktonic carbon fluxes at three stations in the Hudson River estuary during 12 cruises between Octobers of 1996 and 1998. Phytoplankton b...
Episodic nutrient transport to Florida coral reefs
Florida coral reefs soluble reactive phosphate
2014/5/21
This study documents the changes in nutrient fluxes associated with internal tidal bores arriving on Florida Keys
coral reefs and points to biological use of subthermocline nitrate brought onsh...
Horizontal transport and dispersion in the surface layer of a medium-sized lake
Horizontal transport dispersion in the surface layer a medium-sized lake
2014/5/20
Lagrangian GPS drifter experiments, carried out in the surface layer of stratified Lake Kinneret (Israel), are presented. Differential kinematic properties and Lagrangian statistics were calculated an...
Transport of dissolved inorganic carbon from a tidal freshwater marsh to the York River estuary
dissolved inorganic carbon freshwater marsh
2014/5/20
The cycling of dissolved inorganic carbon (DIC) and the role of tidal marshes in estuarine DIC dynamics were
studied in a Virginia tidal freshwater marsh and adjacent estuary. DIC was measured over d...
Population growth and transport of the red tide dinoflagellate, Noctiluca scintillans, in the coastal waters off Sydney Australia, using cell diameter as a tracer
Population growth transport of the red tide dinoflagellate Noctiluca scintillans, in the coastal waters off Sydney Australia using cell diameter as a tracer
2014/5/20
Spatial abundance patterns of the heterotrophic dinoflagellate, Noctiluca scintillans, were investigated along the southeast coast of Australia to address the hypothesis that population growth of Noct...
A model of sediment transport over an intertidal transect, comparing the influences of biological and physical factors
A model of sediment transport over intertidal transect, comparing the influences biological and physical factors
2014/5/27
This paper compares modeled biotic and physical effects on intertidal sediment transport, using parameterizations that are based on laboratory and field experiments. A one-dimensional model of an inte...
Avoiding offshore transport of competent larvae during upwelling events: The case of the gastropod Concholepas concholepas in central Chile
Avoiding offshore transport competent larvae upwelling events gastropod Concholepas concholepas central Chile
2014/5/27
The coast of central Chile is characterized by the occurrence of coastal upwelling during the austral spring and summer seasons, which probably has important consequences for the cross-shelf transport...
The use of flushing time, residence time, and age as transport time scales
flushing time residence time age as transport time scales
2014/5/26
Applications of transport time scales are pervasive in biological, hydrologic, and geochemical studies yet these times scales are not consistently defined and applied with rigor in the literature. We ...
The roles of predation and postlarval transport in recruitment of the soft shell clam (Mya arenaria)
predation and post larval transport soft shell clam
2014/5/26
Rates of mortality and transport of newly settled benthic invertebrates can be very high and potentially have profound effects on patterns of recruitment. We used the soft shell clam Mya arenaria as a...
The influence of filter-feeding benthic macroinvertebrates on the transport and deposition of particulate organic matter and diatoms in two streams
fi lter-feeding benthic macroinvertebrates diatoms
2014/6/9
The transport and deposition of particulate organic matter (POM) in streams has received much attention in recent
years. As with many ecosystem processes, determining the relative importance of physi...
