A transient Mixing Cell Model (MCM) was developed for assessing groundwater fluxes in complex hydro-geological basins prevailing transient groundwater flow system. It is aimed for complex systems with vague sub-aquifer structure, lack of hydro-geological information.

Past Events

OCTOBER 20, 2014

Radiogenic helium-4 produced by the alpha-decay of uranium and thorium in the Earth's mantle and crust is degassed to the atmosphere and eventually escapes to outer space. Assuming an equilibrium between production and degassing, the continental crust is estimated to provide about 70% of the total Earth degassing flux.

Climate variability and change has the potential to cause significant impacts on our economic, ecological, social, and cultural resources. Hurricanes Sandy and Irene provide current examples of such random disruptions. In a changing climate, civil infrastructures (such as dams, bridges, and culverts) are increasingly compromised during extreme precipitation events.

OCTOBER 15, 2014

Water shortages, and the prospect of such shortages, have been repeatedly faced and addressed as population and economic growth placed increasing demands on available water over the past century. Such challenges have been most common in arid areas, but also have been encountered in some more humid portions of the US during times of drought.

High–resolution (4 km; hourly) regional climate modeling is utilized to resolve March–May hazardous convective weather east of the U.S. Continental Divide for a historical climate period (1980–90). A hazardous convective weather model proxy is used to depict occurrences of tornadoes, damaging thunderstorm wind gusts, and large hail at hourly intervals during the period of record.

The University of Alaska Fairbanks with other partners conducts coastal aquatic resource surveys as part of the Alaska Monitoring and Assessment Program (AKMAP). Within Alaska’s Arctic two major coastal surveys – Aleutian Islands and Northeastern Chukchi Sea – have been completed, with a 2015 survey planned for estuaries within the National Petroleum Reserve – Alaska (NPR–A).
