Exploring the Relationships Between Stable Water Isotope Ratios and Large Scale Atmospheric Circulation in Paleoclimate Settings Using an Isotope-Enabled General Circulation Model

Creator:: Niezgoda, Kyle
Abstract:: Climate model simulations and paleoclimate proxies are two tools that enable an understanding of the climate history of the Earth. When utilized together, they form a powerful paradigm for understanding past changes. Proxies are the only physical link to the past conditions on Earth, and models “fill in the gaps”...

A petrogenetic model for the Caribbean large igneous province

Creator:: Krawl, Kyle A.
Abstract:: The Caribbean Plateau is an oceanic large igneous province (CLIP). A widely accepted model for LIP petrogenesis proposes that these large bodies of igneous rock are formed by decompression melting associated with upwelling mantle plume heads during the initiation of hotspot activity. According to this classical model, petrogenesis occurs over...
