Jurassic sea life new fossil site
2017/1/25
A trove of exceptionally preserved Jurassic marine fossils discovered in Canada, rare for recording soft-bodied species that normally don’t fossilize, is expanding scientists’ view of the rich marine ...
The Energetics of Overturning Structures：Implications for the Theory of Fossil Turbulence
Fossil Turbulence Energetics Overturning Structures
2009/1/19
A large number of oceanic and freshwater microstructure observations are analyzed to determine the energetic state of the turbulence. The total available energy and a time scale for dissipating the to...
Spatial variability of stable isotopes and fossil pigments in surface sediments of Alaskan coastal lakes: Constraints on quantitative estimates of past salmon abundance
Spatial variability stable isotopes fossil pigments surface sediments Alaskan coastal lakes Constraints on quantitative estimates past salmon abundance
2006/5/4
We quantified spatial patterns of stable isotopes of N and C (δ15N, δ13C) and fossil pigment concentrations in the uppermost 10 mm of sediment (,10 yr) from 74 profundal locations and three spawning-s...
Postindustrial enhancement of aragonite undersaturation in the upper tropical and subtropical Atlantic Ocean: The role of fossil fuel CO2
Postindustrial enhancement aragonite undersaturation upper tropical subtropical Atlantic Ocean fossil fuel CO2
2004/5/14
The dissolution of aragonite particles in the ocean primarily depends on the degree of undersaturation of seawater with respect to that mineral. Most of the upper Atlantic Ocean, particularly north of...
