Mollusk graveyards time machines oceans pristine past
2017/3/14
A Florida Museum of Natural History study shows that mollusk fossils provide a reliable measure of human-driven changes in marine ecosystems and shifts in ocean biodiversity.Collecting data from ...
Electronic structure of pristine and K-doped solid picene: Non-rigid-band change and its implication for electron-intramolecular-vibration interaction
Electronic structure of pristine K-doped solid picene: Non-rigid-band change electron-intramolecular-vibration interaction
2010/11/19
We use photoemission spectroscopy to study electronic structures of pristine and K-doped
solid picene. The valence band spectrum of pristine picene consists of three main features
with no state at t...
Cloud condensation nuclei in pristine tropical rainforest air of Amazonia: size-resolved measurements and modeling of atmospheric aerosol composition and CCN activity
Cloud condensation nuclei pristine tropical rainforest air Amazonia atmospheric aerosol composition CCN activity
2009/10/13
Atmospheric aerosol particles serving as cloud condensation nuclei (CCN) are key elements of the hydrological cycle and climate. We have measured and characterized CCN at water vapor supersaturations ...
Importance of intertidal sediment processes and porewater exchange on the water column biogeochemistry in a pristine mangrove creek (Ras Dege, Tanzania)
intertidal sediment processes porewater exchange water column biogeochemistry
2010/1/14
We sampled a tidal creek (Ras Dege, Tanzania) during a 24-h cycle to document the variations in a suite of creek water column characteristics and to determine the relative influence of tidal and biolo...
Seasonal bioavailability of dissolved organic carbon and nitrogen from pristine and polluted freshwater wetlands
Seasonal bioavailability pristine
2014/5/19
We examined the chemical composition and bioavailability of dissolved organic carbon (DOC) and nitrogen
(DON) from two pristine and two polluted cedar bog wetlands across three seasons. Pristine and ...
