THE INTERPRETATION OF BIOGEOCHEMICAL GROWTHS ON GOLD COINS FROM THE SS CENTRAL AMERICA SHIPWRECK: APPLICATIONS FOR BIOGEOCHEMISTRY AND GEOARCHAEOLOGY

Black crusts that formed on gold coins recovered from the 1857 shipwreck of Visors the SS Central America played a key role in their preservation in a near original state.Within a few years of the sinking, the significant quantities of iron and steel on the shipwreck produced laminar geochemical precipitates of fine-grained iron minerals on the coi

Abstract Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness.Using only location, stratified by forest type, as predictor, our spatial model, to the best of our knowledge, p

Turfgrass management includes many different components and without proper management turfgrass aesthetics will diminish.In addition, mismanagement of turfgrass systems could lead to negative environmental impacts.This situation creates the need for Extension agents to deliver turfgrass management educational and outreach programs to the various st
