Late Holocene evolution of Currituck Sound, North Carolina, USA : environmental change driven by sea-level rise, storms and barrier island morphology
(East Carolina University, 2012)Coastal evolution is an increasingly important area of study, especially with the projected rise in sea level, increase in storm intensity, and population increases along the nation's coasts. In order to predict how the ... -
Latitudinal difference in biodiversity caused by higher tropical rate of increase
(East Carolina University, 2002-06-11)Tropical diversity has generally exceeded temperate diversity in the present and at points in the past, but whether measured differences have remained relatively constant through time has been unknown. Here we examine ... -
Macondo-1 well oil-derived polycyclic aromatic hydrocarbons
(East Carolina University, 2012-01-14)Mesozooplankton (>200 mm) collected in August and September of 2010 from the northern Gulf of Mexico show evidence of exposure to polycyclic aromatic hydrocarbons (PAHs). Multivariate statistical analysis revealed that ... -
Macondo-1 well oil-derived polycyclic aromatic hydrocarbons in mesozooplankton from the northern Gulf of Mexico
(2012)Mesozooplankton (>200 μm) collected in August and September of 2010 from the northern Gulf of Mexico show evidence of exposure to polycyclic aromatic hydrocarbons (PAHs). Multivariate statistical analysis revealed that ... -
MAJOR AND TRACE ELEMENT CHEMICAL COMPOSITION OF GAHNITE FROM GRANITIC PEGMATITES AND A METAMORPHOSED MASSIVE SULFIDE DEPOSIT : SIGNIFICANCE FOR PEGMATITE FRACTIONATION AND DISCRIMINATION BETWEEN Li-RICH AND Li-POOR PEGMATITES
(East Carolina University, 2014)Rare-element granitic pegmatites are common hosts to economic deposits of rare metals, including Li, Ta, and rare-earth elements, which are increasing in economic importance due to advancing technology. Gahnite (ZnAl₂O₄) ... -
Mineralogy, Geochemistry, and Genesis of the Valentines Iron Formation, Nico Pérez Terrane, Eastern Uruguay, and Significance for the Redox Conditions of Early Earth's Oceans
(East Carolina University, 2015)The Valentines Iron Formation of eastern Uruguay is one of three well-defined rock units that comprise the Valentines Formation, and is commonly interlayered with felsic and intermediate granulites. The iron formations ... -
Miocene Seismic Stratigraphy, Structural Framework, and Sea-Level Cyclicity: North Carolina Continental Shelf
(1982-12)Preliminary interpretations of over 1000 km of high-resolution seismic reflection data, supplemented by over 100 9-m vibracores, have delineated the shallow stratigraphic and structural framework for several Miocene ... -
Modern Sedimentation And Estuarine Shoreline Change Around Roanoke Island, North Carolina
(East Carolina University, 2015)Croatan and Roanoke sounds in North Carolina (NC) are regions constantly undergoing geomorphic changes associated with sea-level rise, storm events, and anthropogenic modification. These estuaries are part of the larger ... -
Morphology, Geologic History and Dynamics of Wimble Shoals, Rodanthe, NC
(East Carolina University, 2017-05-03)Barrier islands around the world protect estuaries and mainland areas, creating important habitat as well as environmentally and economically valuable property. Barrier islands represent 10%, of global shorelines and are ...
