(2012-10-19)Previous studies showed that sea surface salinity (SSS) in the Florida Straits as well as Florida Current transport covaried with changes in North Atlantic climate over the past two millennia. However, little is known about ...

(Texas A&M University, 2005-02-17)Approximately 6.6 million years ago in the Eastern Equatorial Pacific a large increase in biogenic mass accumulation rates (MARs) occurred. This increased level of biogenic mass accumulation persisted until about 4.4 Ma ...

(Texas A&M University, 2005-11-01)To better understand how the evolution of Cenozoic deep-water circulation related to changes in global climate and ocean basin configuration, we generated Nd isotope records from Ocean Drilling Program sites in the ...
-
(2017-01-17)In the modern ocean, important water masses originating in the North Atlantic Ocean and Southern Ocean intersect the Namibian margin of southwest Africa at various water depths: Antarctic Intermediate Water (AAIW) occurs ...
-
(2012-07-16)Global climate is controlled by two factors, the amount of heat energy received from the sun (solar insolation) and the way that heat is distributed Earth's surface. Solar insolation varies on timescales of 10s to 100s of ...
-
(2016-10-28)The Mid-Pleistocene Transition (MPT), one of the largest climate shifts in the late Quaternary, was characterized by widespread, gradual global cooling accompanied by expansion of Northern Hemisphere ice sheets and a shift ...
-
(Texas A&M University, 2006-08-16)We test the fidelity of shallow-water gastropod skeletons as multi-proxy archives of seasonal paleo-environmental change by performing isotopic and trace-metal analyses on specimens of Conus ermineus from the Gulf of Mexico. ...

The Middle Miocene Climatic Optimum (MMCO) is a time period that demonstrated significantly high temperatures, which interrupted the mid-Cenozoic cooling trend. While there is abundant data on deep ocean temperatures during ...

(2016-05-10)The Atlantic Meridional Overturning Circulation is an important feature of Earth’s climate system that regulates hemispheric heat distribution. This dissertation takes an in-depth look at how the strength of this circulation ...
