Examination of polished sections of manganese micronodules
from metalliferous sediments from the Bauer Deep reveals sequences
of ferromanganese deposition which are consistent for micronodules
from a single sediment sample and imply a common depositional
history for members of such assemblages. The relatively simple
'stratigraphy' of manganese micronodules, as compared to...
Easter Island and Sala y Gomez are part of the Sala y Gomez
Ridge, a broad band of high topography and scattered seamounts
extending ESE from the East Pacific Rise. It has been proposed that
the Sala y Gomez Ridge results from the movement of the Nazca Plate
over a...
Coal power is the prominent source of energy in the United States (U.S.) and around the world. The byproducts of coal power contain many of the same radioactive nuclides that are found in the local environment just in higher concentrations. With so much of this ash being stockpiled, the amount...
