Bathymetry Based Modeling Of Subaxial Magma Flows Under The Mid-Atlantic Ridge, 0 To 30° N, Adam R. Tjoelker, Neil Van Kanegan, C. Renee Sparks
Bathymetry Based Modeling Of Subaxial Magma Flows Under The Mid-Atlantic Ridge, 0 To 30° N, Adam R. Tjoelker, Neil Van Kanegan, C. Renee Sparks
Summer Research
The study area for this investigation includes the MidAtlantic Ridge (MAR) system from the Equator to 30° north latitude. In its entirety, the MAR system runs from around 87° N to 54° S through roughly the center of the Atlantic Ocean. The width of the Ridge ranges from 1000-1300 km (Liu et al., 2021). After conducting a similar study of the MAR system from the Equator to 30° S latitude, (Detmer et al., 2021 in review), the addition of magmatic modelling in this study enables continued investigation of the MAR’s tectonic fabric and allows us to test our hypotheses for …

Trace Elements Of Volcanic Soils And Coffee – Kona, Kathryn Mollison, Nathaniel Bos, C. Renee Sparks
Summer Research
Much of the world's coffee is grown on soils that have developed from the chemical and physical weathering of basalt, a volcanic rock with relatively high iron content. Volcanic rocks vary in composition depending on the relative amounts of major elements that produce minerals such as plagioclase, pyroxene and olivine. The breakdown of these minerals is dependent on climate and slope as well as the initial composition. Chemical weathering associated with climate, eventually leads to the development of clay minerals, oxides, and hydroxides that are key components of the soil chemistry. The soil transfers elements to the coffee plant through …
