Geochemical assessment of mixing advanced treated wastewater and groundwater in the Harmony Grove Basin, Southern California Anthony Fisher ABSTRACT The Harmony Grove basin aquifer is located in San Diego California. This location is being sought after by the Rincon del Diablo Municipal Water District for storage of advanced treated wastewater (ATW). After storage, pumping of groundwater is proposed for potable reuse. The project consultant sampled and analyzed groundwater chemical...

Growth Dynamics in the Intertidal Barnacle Megabalanus: Development of a Subseasonal Paleoceanographic Archive Julio F. Morin ABSTRACT The arthropod Megabalanus coccopoma is indigenous to coastal Baja California, but migrated up to San Diego due to an El Nino event in the early 80s (Newman and McConnaughey 1987). Megabalanus dates back to the Miocene (Doyle et al. 2007) is a useful local indicator of exposure and submergence intervals due to their feeding habits which correlates to...

Paleodepth reconstruction through the Pennsylvanian Finis Shale of Texas: Insights from brachiopod oxygen isotopes Leah Carrigan ABSTRACT The Upper Pennsylvanian Finis Shale occurs within the Graham Formation of the Cisco Group and represents a mud-dominated environment along the eastern shelves of the sub-equatorial Midland Basin (Pierce et al., 2010). In a representative section of the Finis Shale, Forcino et al. (2010) documented a fundamental decrease in the abundance and biomass...

The West Bullion-Mesquite Lake Fault Step-Over: Assessment and Comparison With Faults of the Eastern California Shear Zone, Twenty-Nine Palms Marine Corps Base, California Kaitlin Wessel ABSTRACT Twenty-nine Palms Marine Corps Base is positioned in a step-over region between the West Bullion Fault and Mesquite Lake Fault. Both of these belong to a series of transform faults located in the Mojave Desert called the Eastern California Shear Zone (ECSZ) that trends northwest to southeast....

Enigmatic new Osagean unit sitting atop Lower Mississippian Joana Limestone at Granite Mountain Island, Middle Range, West-Central Utah Luke A. Ranieri ABSTRACT The enigmatic Middle Range (MR) unit that unconformably overlies the Joana Limestone in the Middle Range, Utah, was deposited on the eroded surface of the Joana bank of the Antler forebulge in the Lower Mississippian in warm, tropical sea water, and fits the classification of a Waulsortian or Waulsortian-like mudmound due to...
