Simulating The Effect Of Matrix Diffusion In Fractured Porous Media With Dual Domain Mass Transfer: A Modeling Comparison

Weingarten , Matthew 1 ; Hsieh , Paul 2 1 University of ÃÛÌÇÖ±²¥ at Boulder, Boulder, CO, USA 2 U.S. Geological Survey, Menlo Park, CA, USA Solute transport through fractured porous rocks can be described by advective-dispersive transport through the fractures and diffusive transport through the unfractured matrix. The effect...

Middle Holocene Natural Variability Of Temperature And Salinity In The North Atlantic Ocean, Southwest Of Iceland

Underhill , Vivian R 1 1 University of ÃÛÌÇÖ±²¥ With rising global temperatures, a major concern is that fresh water from melting glaciers and the Greenland ice sheet will slow down global oceanic circulation patterns, in particular the North Atlantic Current (NAC). The NAC, an extension of the Gulf Stream,...
