December 2011 Geology highlights

The December 2011 Geology issue presents several studies. Researchers discovered microfossils in the Tayshir Formation, Mongolia, shedding light on ancient life forms. Additionally, a study investigated melt migration mechanisms, finding evidence for porosity waves in the sub-arc mantle of Kohistan Island Arc.

Measuring a monster

The study highlights the catastrophic effects of the December 26, 2004 tsunami on Banda Aceh and Lohknga in Indonesia. Water reached 9 meters at the shoreline and over 15 meters inland, with wave-driven sea water inundating areas up to 25 meters above sea level.

Mega-tsunami to devastate US coastline

A new model predicts a mega-tsunami could devastate the US coastline, with wave heights reaching 100 meters on the West Saharan shore and 50 kilometers high in Florida. The energy released would be equivalent to the electricity consumption of the entire United States in half a year.

Sea level rise behind coastal tree deaths

A University of Florida study found that rising sea levels are causing cabbage palms and other coastal trees to die due to saltwater exposure. The phenomenon may be more immediate than thought, with small increases in sea level affecting large areas of flat coastline on the west coast.

UF Scientist Seeks Super Sea Oats

A University of Florida researcher has found genetic differences in sea oats on the Gulf Coast, which could lead to the development of a "super" sea oat that can stabilize dunes during storms. The goal is to select and propagate sea oats with desirable traits such as quick root growth and extensive rhizome systems.

Evidence For Earliest Maritime-Based Societies In The Americas Reported In Science Magazine

Researchers have uncovered ancient fragments of sea shells and cutting tools at two sites in Peru, dating the earliest evidence of maritime-based societies in the Americas between 11,000 and 13,000 years ago. The discoveries challenge traditional views on Paleoindian societies and suggest a more diverse set of strategies for survival.
