Record-high Arctic freshwater affecting marine environment and Atlantic Ocean currents（图）
Record-high Arctic freshwater marine environment Atlantic Ocean currents
2021/3/19
Freshwater is accumulating in the Arctic Ocean. The Beaufort Sea, which is the largest Arctic Ocean freshwater reservoir, has increased its freshwater content by 40% over the past two decades. How and...
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 ...
A 180-Million-Year Record of Sea Level and Ice Volume Variations from Continental Margin and Deep-Sea Isotopic Records
180-Million-Year Record Sea Level and Ice Volume Variations Continental Margin Deep-Sea Isotopic Records
2015/7/9
The geologic record provides constraints on the rates, amplitudes, and mechanisms controlling globally averaged (eustatic) and relative (eustatic plus subsidence/uplift) changes of sea level on variou...
The following is part sixteen in a series on the National Science Foundation's Long-Term Ecological Research (LTER) Network. Visit parts one, two, three, four, five, six, seven, eight, nine, ten, elev...
Multidecadal climate oscillations detected in a transparency record from a subtropical Florida lake
Multidecadal climate oscillations transparency record subtropical Florida lake
2014/4/17
Synchronous interannual variability in water transparency observed in neighboring lakes has been linked to regional precipitation and resultant runoff of dissolved organic material, but many climate f...
Selecting Record Length and Digitization Rate for Near-Bed Turbulence Measurements
Selecting Record Length Near-Bed Turbulence Measurements Digitization Rate
2009/2/16
Measured values of turbulence parameters (such as mean, variance or covariance of velocity) will depend on the record length and digitization rate chosen for their computation. Six factors which gover...
A seventy-two-year record of diminishing deep-water oxygen in the St. Lawrence estuary: The northwest Atlantic connection
A seventy-two-year record diminishing deep-water oxygen St. Lawrence estuary The northwest Atlantic connection
2014/5/13
Oxygen concentrations in the bottom waters of the Lower St. Lawrence estuary (LSLE) decreased from 125 μmol L-1 (37.7% saturation) in the 1930s to an average of 65 μmol L-1 (20.7% saturation) for the ...
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...
Seasonal and interannual particle export in an African rift valley lake: A 5-year record from Lake Malawi, southern East Africa
Seasonal interannual particle export an African rift valley lake A 5-year record Lake Malawi southern East Africa
2014/5/19
A time-sequencing sediment trap was deployed at 300-350 m in Lake Malawi, East Africa, from 1987 to 1992 to measure particulate export to the deep, anoxic hypolimnion in the northern and central lake ...
Winter storms: Sequential sediment traps record Daphnia ephippial production, resuspension, and sediment interactions
Sequential sediment traps resuspension, sediment interactions
2014/5/16
or species that do not over-winter, an essential part of the life cycle is the production of diapausing eggs. We
use sequential sediment traps in southern Lake Michigan (1997–2000) to capture settlin...
A modern isotope record of changes in water and carbon budgets in a groundwater-fed lake: Blue Lake, South Australia
modern isotope record changes in water carbon budgets groundwater-fed lake Blue Lake South Australia
2014/5/22
Groundwater is often a major component of lake water and chemical balances. Alteration in catchment subsurface water balances through land-use change and pumping can affect lake biogeochemical cycles ...

234Th/238U disequilibrium provide accurate record particulate organic carbon the upper ocean
2014/5/20
The magnitude of the flux of biogenic particulate organic carbon (POC) exported from the surface waters of the world ocean and remineralized at depth is critical to constraining models of the global c...
