The RASA Program represents a systematic effort to study a number of the Nation's most important aquifer systems, which in aggregate underlie much of the country and which represent an important component of the Nation's total water supply. In general, the boundaries of these studies are identified by the hydrologic extent of each system and accordingly transcend the political subdivisions to which investigations have often arbitrarily been limited in the past. The broad objective for each study is to assemble geologic, hydrologic, and geochemical information, to analyze and develop an understanding of the system, and to develop predictive capabilities that will contribute to the effective management of the system. The use of computer simulation is an important element of the RASA studies, both to develop an understanding of the natural, undisturbed hydrologic system and the changes brought about in it by human activities, and to provide a means of predicting the regional effects of future pumping or other stresses. The final interpretive results of the RASA Program are presented in a series of U.S. Geological Survey Professional Papers that describe the geology, hydrology, and geochemistry of each regional aquifer system. Each study within the RASA Program is assigned a single Professional Paper number, and where the volume of interpretive material warrants, separate topical chapters that consider the principal elements of the investigation may be published. The series of RASA interpretive reports begins with Professional Paper 1400 and thereafter will continue in numerical sequence as the interpre­ tive products of subsequent studies become available.

Paradoxically, despite a long history of inquiry into spit and barrier formation, understanding of the dynamics and sedimentary history of tombolos over the Holocene timescale is poor. At Tyre and Alexandria we demonstrate that these rare coastal features are the heritage of a long history of natural morphodynamic forcing and human impacts. In 332 BC, following a protracted seven-month siege of the city, Alexander the Great's engineers cleverly exploited a shallow sublittoral sand bank to seize the island fortress; Tyre's causeway served as a prototype for Alexandria's Heptastadium built a few months later. We report stratigraphic and geomorphological data from the two sand spits, proposing a chronostratigraphic model of tombolo evolution. © 2008 Elsevier B.V. All rights reserved.

  • A Fish Fauna from the Lowermost Bartonian of the Transylvanian Basin, Romania
    Palaeontologia Electronica palaeo-electronica.org A fish fauna from the lowermost Bartonian of the Transylvanian Basin, Romania Nicolae Trif, Vlad Codrea, and Viorel Arghiuș ABSTRACT A fish fauna newly discovered in the middle Eocene marine sediments cropping out near the village of Luna de Sus, Romania, completes the fossil record of the East- ern European region. Teeth belonging to 15 species of Chondrichthyes and two spe- cies of Actinopterygii are herein recorded from the lowermost Bartonian deposits. These Paleogene fish document a marine tropical environment of medium deep waters in the northwestern area of the Transylvanian Basin. The vertical distributions of extant equivalent taxa allow a sea depth estimation of 100 to 200 m. The warm climate is doc- umented by both the present faunal assemblage and previous palynological studies. It is important to note the presence of the scarcely known and poorly understood pycno- dont species Phacodus punctatus and of the oldest representative of Labridae from this Carpathian area. The diversity of the fauna was found to be average compared to some areas from Western Europe or North Africa, but it falls within the regional diver- sity range of the Eastern European localities.

Five stratigraphic sections in Grenada County were measured and described. Twenty-one sand and sandstone samples, and 2 mud samples were collected from all sections. Textural analyses were performed on all 23 samples to determine their lithologic properties. Petrographic descriptions and modal analyses were performed on thin sections made from the 21 sand and sandstone samples, and 400 grains were point counted in each sample.

  • Draft Environmental Assessment for Review and Comment
    United States Department ofthe Interior FISH AND WILDLIFE SERVICE Texas Chenier Plain NWR Complex June 15, 2017 Dear Reviewer: This is to provide notification of availability of a U.S. Fish and Wildlife Service (USFWS) Draft Environmental Assessment for review and comment. The Draft Environmental Assessment addresses the issuance of an Operational Permit by the USFWS for two proposed oil and natural gas drilling and production project on the Mcfaddin National Wildlife Refuge (Refuge) in Jefferson County, Texas. The project has been proposed by OLEUM Exploration, LLC ofBrodheadsville, Pennsylvania. The company possesses valid leases to explore and/or develop oil and gas reserves underlying the refuge from the rightful mineral owners. The purpose for the proposed Federal action is to insure that mineral rights holders have reasonable access to develop their non-Federal oil and gas interests and minimize impacts to refuge resources to the extent practicable under the USFWS's 50 CFR Part 29, Subpart D regulations for managing non-Federal oil and gas on USFWS administered lands and waters. Issuance ofthe Operations Permit in the end should protect the human environment in such a way as to further the Refuge's efforts to achieve its established purposes, and the general resource conservation mission ofthe USFWS. Written comments may be mailed to Texas Chenier Plain Refuge Complex at P.O. Box 278, Anahuac, TX 77514. Comments may also be electronically mailed to monique [email protected] with "OLEUM EA Comments" in the subject line. All comments sent must be post marked or electronically sent by June 29th, 2017. If you need additional information, feel free to visit our offices or contact myself, Monique Slaughter, Oil and Gas Specialist for the refuge complex (409) 267-3337 or Refuge Manager Douglas Head at (409) 971-2909.

The deep interior of the Earth, however, remains as inaccessible as ever. This is the realm of solid-Earth geophysics, which still mainly depends on observations made at or near the Earth's surface. Despite this limitation, a major revolution in knowledge of the Earth's interior has taken place over the last forty years. This has led to a new understanding of the processes which occur within the Earth that produce surface conditions outstandingly different from those of the other inner planets and the moon. How has this come about? It is mainly the results of the introduction of new experimental and computational techniques into geophysics.

Riv. It. Paleontol. Strat., 126(2): 395-446. Keywords: K-Pg boundary event; Gadiformes; Heterenchelyidae; otolith; extinction; survival. Abstract. Otolith assemblages have rarely been studied across the K-Pg boundary. The late Maastrichtian Kemp Clay of northeastern Texas and the Fox Hills Formation of North Dakota, and the early Danian Clayton Formation of Arkansas therefore offer new insights into how teleost fishes managed across the K-Pg boundary as reconstructed from their otoliths. The Kemp Clay contains 25 species, with 6 new species and 2 in open nomenclature and the Fox Hills Formation contains 4 species including 1 new species. The two otolith associations constitute the Western Interior Seaway (WIS) community.
