CHARACTERIZATION AND DEVELOPMENT OF FRACTURE PATTERNS IN DOMED SEDIMENTARY STRATA, PULPIT ARCH, HENRY MOUNTAINS, UTAH
(East Carolina University, 2020-01-10)Fractures in sedimentary rock can be an important factor in influencing fluid migration in the subsurface. In high-porosity sandstones in the upper crust, deformation such as folding typically results in the production of ... -
Characterizing Coastal Subenvironments with Modern Foraminiferal Assemblages: Bear Island and Bogue Banks, North Carolina
(East Carolina University, 2018-08-30)North Carolina's coastline consists of an extensive barrier island system, with inlets acting as pathways for the exchange of sediment and water from estuarine and open ocean environments. Reconstructing past coastal changes ... -
Comparative impacts of two major hurricane seasons on the Neuse River and western Pamlico Sound ecosystems
(East Carolina University, 2004-06-22)Ecosystem-level impacts of two hurricane seasons were compared several years after the storms in the largest lagoonal estuary in the U.S., the Albemarle-Pamlico Estuarine System. A segmented linear regression flow model ... -
Comparison of quantification methods to measure fire-derived (black/elemental) carbon in soils and sediments using reference materials from soil, water, sediment and the atmosphere
(2007)Black carbon (BC), the product of incomplete combustion of fossil fuels and biomass (called elemental carbon (EC) in atmospheric sciences), was quantified in 12 different materials by 17 laboratories from different ... -
A comparison of watershed nitrogen loading and watershed nitrogen exports from on-site wastewater treatment systems and centralized sewer systems in the North Carolina Coastal Plain
(East Carolina University, 2013)Elevated nitrogen (N) concentrations in groundwater may cause adverse effects to adjacent surface water bodies. In North Carolina, half of the residences use on-site wastewater treatment systems (OWTS), yet they are typically ... -
Controls on Septic System Wastewater Treatment and Shallow Groundwater Quality in Coastal North Carolina
(East Carolina University, 2009)Excess nitrogen and bacteria concentrations in coastal waters of North Carolina have led to eutrophic conditions, fish kills, and the closure of shellfish waters. Regulatory efforts by the state to reduce nitrogen and ... -
Cyclic Deposition of Neogene Phosphorites in the Aurora Area, North Carolina, and their Possible Relationship to Global Sea-Level Fluctuations
(1982)The Neogene phosphorites in the Aurora Area occur within the Miocene Pungo River Formation (units A, B, C, and D) and the Pliocene Yorktown Formation (lower and upper units). These units are characterized by the following ... -
Decadal-scale evolution of a barrier island : Insights from storm overwash and shoreline change on Ocracoke Island, NC
(East Carolina University, 2014)Eastern North Carolina has over 300 km of barrier islands that comprise the Outer Banks and act as an important buffer from the Atlantic Ocean and boundary to the Albemarle-Pamlico Estuarine System. These islands also draw ...
