STRATAFORM: A Program to Study the Creation and Interpretation of Sedimentary Strata on Continental Margins
Program Sedimentary Strata
2015/8/13
Continental margins are complex regions of the Earth, because they are the interface between terrestrial and marine environments. Many natural processes occurring on land or in the ocean combine to in...
how is sediment transported to the seafloor
along coastlines where the sea ice rarely
melts? Are there distinctive characteristics
of the resulting deposits that label them as
accumulating in ...
Seasonal and diel patterns in sedimentary flux of krill fecal pellets recorded by an echo sounder
echo sounder Seasonal diel patterns
2014/4/2
We used a moored upward-facing 200 kHz echo sounder to address sedimentation of fecal pellets (FPs) from
dielly migrating Meganyctiphanes norvegica. The echo sounder was located on the bottom at 150 ...
Sedimentary phosphorus dynamics and the evolution of bottom-water hypoxia: A coupled benthic–pelagic model of a coastal system
Sedimentary phosphorus dynamics a coastal system
2014/4/8
The present study examines oxygen and phosphorus dynamics at a seasonally hypoxic site in the Arkona basin
of the Baltic Sea. A coupled benthic–pelagic reactive-transport model is used to describe th...
Statistical measures of distribution patterns of silicon and calcium in marine sedimentary layers
Statistical measures distribution patterns silicon calcium marine sedimentary layers
2009/11/3
We analyze electron microscope X-ray spectroscopy data of recent supratidal marine sediments. Statistical measures are used to characterize the distribution of silicon and calcium in different layers ...
Oxygen as a control on sea floor biological communities and their roles in sedimentary carbon cycling
Oxygen sea floor biological communities sedimentary carbon cycling
2014/4/22
13C tracer experiments were conducted at sites spanning the steep oxygen, organic matter, and biological community gradients across the Arabian Sea oxygen minimum zone, in order to quantify the role t...
Dinosterols or dinocysts to estimate dinoflagellate contributions to marine sedimentary organic matter?
Dinosterols dinocysts dinoflagellate marine sedimentary organic matter
2014/4/21
Dinosterol (4α,23,24-trimethyl-5α-cholest-22E-en-3β-ol) is frequently used as an alternative to dinoflagellate cyst (dinocyst) counting in paleoceanography to assess dinoflagellate inputs to marine se...
Sedimentary organic matter geochemistry of Clayoquot Sound, Vancouver Island, British Columbia
Sedimentary organic matter geochemistry Clayoquot Sound Vancouver Island British Columbia
2014/5/9
Surface sediment samples from three interconnected fjords of Clayoquot Sound, British Columbia, were density fractionated (1.6 g cm-3) to isolate discrete organic debris (OD) from mineral-associated o...
Factors controlling d13C values of sedimentary carbon in hypertrophic Baldeggersee, Switzerland, and implications for interpreting isotope excursions in lake sedimentary records
Factors controlling d13C values sedimentary carbon in hypertrophic Baldeggersee Switzerland interpreting isotope excursions lake sedimentary records
2014/5/9
We use stable carbon isotope values (δ13C) in sedimented organic matter and carbonate as proxy indicators of productivity changes in a highly eutrophic to hypertrophic lake. Stable isotope data from a...
Sedimentary geochemical record of human-induced environmental changes in the Lake Brunnsviken watershed, Sweden
Sedimentary geochemical record uman-induced environmental changes
2014/5/19
Environmental changes in Lake Brunnsviken, its watershed, and the greater Stockholm region since the middle
of the nineteenth century have left interpretable geochemical imprints in the bottom sedime...
Modeling detailed sedimentary 210Pb and fallout 239,240Pu profiles to allow episodic events: An application in Chesapeake Bay
sedimentary 210Pb fallout 239,240Pu profiles Chesapeake Bay
2014/6/9
Dependable sediment chronologies are essential to the interpretation of the sedimentary record of past environmental change. In the present article, we use high-resolution chemical and radiochemical d...
