What will be the impact to the ocean if humans are to mine the deep sea? It’s a question that’s gaining urgency as interest in marine minerals has grown.
Linking Sediment Transport and Stratigraphy on the Continental Shelf
Continental Shelf Transport and Stratigraphy
2015/8/13
The goal of the shelf sediment dynamics component of STRATAFORM is to link sediment transport processes active on the continental shelf to the formation and preservation of event beds in shelf sedimen...
The PASTA Project: Investigation of Po and Apennine Sediment Transport and Accumulation
Apennine Sediment Transport Accumulation
2015/7/29
The northwestern Adriatic Sea from the Po River mouth to the Gargano Peninsula (Figure 1) is an ideal location to study sedimentary processes that fill foreland basins and form epicontinental shelves....
Sediment Dynamics in the Adriatic Sea Investigated with Coupled Models
Coupled Models Adriatic Sea
2015/7/29
Several large research programs focused on the Adriatic Sea in winter 2002-2003, making it an exciting place for sediment dynamics modelers (Figure 1). Investigations of atmospheric forcing and oceani...
Coastal Sediment Dynamics and River Discharge as Key Factors Influencing Coastal Ecosystem Productivity in Southeastern Lake Michigan
Coastal Sediment Dynamics River Discharge Coastal Ecosystem Productivity Southeastern Lake Michigan
2015/7/22
A central question addressed by the Episodic Events in the Great Lakes Experiment (EEGLE) was the extent to which the spring phytoplankton bloom in southern Lake Michigan is influenced by a recurrent ...

Winter-Spring Storms Sediment Resuspension Transport Accumulation Patterns Southern Lake Michigan
2015/7/22
The Episodic Events-Great Lakes Experiment was designed to quantify the impacts of major late winter-early spring storms on sediment-water exchange, sediment, and associated constituent transport and ...
Quantifying Benthic Exchange of Fine Sediment via Continuous,Noninvasive Measurements of Settling Velocity and Bed Erodibility
Fine Sediment Noninvasive Measurements Settling Velocity Bed Erodibility
2015/7/22
Benthic exchange of fine sediment has major implications for the structure and function of shelf and estuarine environments. Globally, the transport of particulate organic carbon from the land to the ...
A Decade of Directly Measured Sediment N2 Fluxes:What Can Narragansett Bay Tell Us About the Global Ocean Nitrogen Budget?
Directly Measured Sediment N2 Fluxes Narragansett Bay Global Ocean Nitrogen Budget
2015/7/17
The tight coupling between nitrogen and carbon cycling has important implications for global climate. These two cycles are under growing anthropogenic pressures (e.g., warming temperatures, changes in...
Sediment Dynamics Observed in the Jhoushuei River and Adjacent Coastal Zone in Taiwan Strait
Sediment Dynamics Observed Jhoushuei River Adjacent Coastal Zone Taiwan Strait
2015/7/13
Taiwan's rugged, mountainous terrain, a result of active tectonics, and its monsoonal climate create conditions that produce the greatest sediment yield compared to all land surfaces on Earth. It is e...
Lake trophic status can be determined by the depth distribution of sediment phosphorus
Lake trophic status sediment phosphorus
2014/4/4
In this meta-analysis, we examine how sediment phosphorus (P) burial pattern may be related to trophic state.
We present sediment P profiles from 94 lakes that demonstrate fundamental differences in ...
Differences in benthic metabolism, nutrient fluxes, and denitrification in Caulerpa taxifolia communities compared to uninvaded bare sediment and seagrass (Zostera capricorni) habitats
Differences in benthic metabolism nutrient fluxes denitrification in Caulerpa taxifolia communities uninvaded bare sediment and seagrass Zostera capricorni habitats
2014/4/4
Benthic metabolism, nutrient fluxes, and denitrification were measured in Caulerpa taxifolia communities that had recently invaded (between 2003 and 2008) bare sediments following the loss of Zostera ...
Characterization of stable isotope fractionation during methane production in the sediment of a eutrophic lake, Lake Dagow, Germany
stable isotope fractionation methane production in the sediment eutrophic lake Lake Dagow Germany
2014/4/18
We measuredd13CofCO2,CH4, and acetate-methyl in profundal sediment of eutrophic Lake Dagow by incubation experiments in the presence and absence of methanogenic inhibitors chloroform, bromoethane sulf...
Production of nitrogen gas via anammox and denitrification in intact sediment cores along a continental shelf to slope transect in the North Atlantic
Production of nitrogen gas anammox denitrification intact sediment cores a continental shelf slope transect the North Atlantic
2014/4/17
We measured the production of N2 gas from anammox and denitrification simultaneously in intact sediment cores at six sites along a transect of the continental shelf (50 m) and deeper slope (2000 m) in...
