Late Holocene mud sedimentation and diagenesis in the Firth of Thames: Bentonites in the making
No full textLate Holocene mud sedimentation in the southern Firth of Thames has been described from analysis of a number of shallow marine sediment cores. Three distinct lithofacies are distinguished on the basis of sediment texture and mineralogy. A laterally extensive greenish grey mud, typically bioturbated and massive, with sporadic uncorrelatable interbedded shell layers is termed the Firth of Thames mud facies. Nearer shore sediments are usually coarser and are subdivided into two facies: a siliciclastic sand facies (river mouth sand facies) comprising more prominent interbeds of sand in mud and associated with sedimentation at the mouth of the Waihou River; and a mixed terrigenous-carbonate gravel facies (delta fan gravel facies) associated with deposition on small delta fans adjacent to streams draining the Coromandel Range. The areal distribution of all three facies over the late Holocene has been controlled largely by northward progradation of the coastal Hauraki Lowland associated with the rapid sediment infilling of the Firth of Thames since sea level reached its present height 6500 y B.P. From seismic evidence the Holocene muds are up to 10m thick. The cores in this study penetrated only to 5.5m sub-bottom depth and yielded an oldest radiocarbon age of 5000 y B.P. The age data indicate an average rate of offshore vertical sediment accumulation of 1.5 mm/y.
Up to 15 km of progradation of the southern shoreline of the coastal Hauraki Lowland has occurred over the late Holocene at an average rate of up to 2.5 m/y, notably from 3500 y B.P to 1200 y B.P. Progradation is evidenced by the occurrence of coarsening-upward sequences in nearer shore cores of the Firth of Thames, as well as their changing faunal composition, particularly the upward increase in abundance of the foraminifer Ammonia beccarri, a good indicator of brackish water conditions, which suggests a gradual seaward encroachment of the freshwater influence of the Waihou River over the late Holocene. Basal muds which are similar in composition to marine sediments of the Firth of Thames are overlain by peat dated at 6025 y B.P in a peat core from Kopouatai Peat Bog, and suggest that marine conditions existed in this inland region of the Hauraki Depression prior to 6025 y B.P.
Muds range from silty clays to clayey silts and consist principally of volcanic glass, smectite and halloysite, with smaller amounts of other volcanic-derived siliciclasts and allophane and illite, as well as skeletal carbonate (mainly aragonite) and organic matter. A contemporaneous decrease in the abundance of volcanic glass (55-15 wt % down-core) and an increase in smectite concentration (8-45 wt % down-core) occurs with sub-bottom depth. Specific mineralogical analyses (XRD and IR) and evidence from scanning electron microscopy suggest the smectite is montmorillonitic in composition and authigenic in nature. Moreover, the absence of smectite in the bottom sediments of rivers draining the Hauraki Lowland precludes a detrital origin.
The diagenetic transformation of volcanic glass to smectite in sediments of the Firth of Thames is described by a sequential kinetic model which involves a parabolic dissolution coupled with a first order precipitation of smectite via the formation of an intermediate hydrated glass phase. The rate constant calculated from the sequential kinetic model is 3.35 x 10⁻⁴y⁻¹. The half-life of the glass is 1475 y, implying rapid early diagenetic alteration of volcanic glass to smectite to form late Holocene bentonitic deposits. Thermodynamic stability considerations imply that the first order precipitaion of smectite may be favoured by conditions of pH and Na⁺ activity typical of interstitial fluids having sea water salinity under mildly anoxic conditions

Reservoir characterization and potential of the old red sandstone around the inner moray firth, NE Scotland
No full textOld Red Sandstone deposition in North East Scotland occurred during Devonian times within the Orcadian Basin, a northeast-southwest elongated structure. The basin formed in an extensional tectonic regime that resulted from gravitational collapse of over thickened Caledonian crust. A half graben topography resulted with the faulting largely controlled by crustal heterogeneities inherited from the Caledonian period of mountain building. The ORS around the Inner Moray Firth is a red bed sequence deposited on the southern margin of the Orcadian Basin. The succession consists predominantly of braided fluvial sandstones, silts tones and mudstones, with lesser amounts of aeolian sandstones, evaporitic sabkha sandstones (only in the Upper ORS), and lacustrine mudstones and limestones (Middle ORS only). Lithologically the sandstones are coarse to fine grained, moderately to well sorted, and predominantly sublitharenite in composition. The sandstones show the following diagenetic sequence: (1) Eodiagenesis: formation of clay/Fe oxide rims and the dissolution of lithic fragments; (2) Mesodiagenesis: the precipitation of a blocky, irregularly distributed, calcite cement; and (3) Telodiagenesis: a major dissolution event following inversion during the late Carboniferous involving partial removal of the calcite cement, feldspars (predominantly plagioclase), and lithic fragments (mainly sedimentary and metamorphic) and an associated precipitation of kaolinite. Intergranular macroporosity is most abundant with lesser amounts of intragranular and microporosity. Porosity values are quite low (an average of 6% for both the Middle and the Upper ORS) and permeabilities are also poor (an average of 17 and 51mD respectively). Porosity reduction has occured mainly through cementation rather than compaction. The low permeabilities are thought to be due to low pore interconneclivity because of the patchy nature of the calcite cement, and to the presence of pore lining/filling kaolinite. Diagenesis has acted to largely overprint the primary permeability characteristics of the different lithofacies identified within the sandbodies. Some fractured samples however, had permeabilities of up to 1400mD similar to the situation in the Buchan Field ORS fluvial sandbody reservoir, where fracturing is the major control on reservoir characteristics. Reservoir heterogeneities occur on a variety of scales within the ORS and have a marked effect. At the microscale diagenetic heterogeneitites have reduced porosity and permeability to very low levels. Cross-bedding and other sedimentological structures exert directional anisotropics on the permeability. Additionally, the Middle ORS is separated into discrete segments from 10-100m thick by laterally extensive lacustrine deposits, resulting in there being virtually no vertical connectivity between sandbodies. The Upper ORS has a much higher sandbody connectivity with only Local horizons of thin, discontinuous fluvial mudstones which are scarce due to syndepositional erosion
Population ecology of bottlenose dolphins (Tursiops truncatus) off the east coast of Scotland
No full textThe population of bottlenose dolphins off the east coast of Scotland has been studied since the late 1980s, initially focused on the inner Moray Firth, where a Special Area of Conservation (SAC) was designated under the EU Habitats Directive. The population has since expanded its distributional range and currently ranges from the Moray Firth to the Firth of Forth. The main aims of this thesis were: (1) to estimate population parameters for this population using a 25 year individual recognition dataset, and (2) to increase knowledge of the distribution and abundance of dolphins in areas outside the SAC, especially to investigate areas of high use in St Andrews Bay. Apparent survival rate for adults and sub–adult dolphins was estimated at 0.946 (SE=0.005) accounting for temporary emigration caused by the population’s range expansion. Sex-specific survival was estimated for males (0.951, SE=0.013) and females (0.956, SE=0.011) using multistate models to minimize bias caused by individuals of unknown sex. Using a newly developed approach, fecundity rate was estimated at 0.222 (95% CI=0.218-0.253) from an expected mean inter-birth interval of 4.49 yrs (95% CI=3.94-4.93). Total population size was estimated as ~200 individuals, after accounting for temporary emigration and for heterogeneity in capture probabilities. In St Andrews Bay, an area used regularly in summer by approximately half the estimated population, habitat use modelling identified the entrance to the Firth of Tay and waters around Montrose as high use areas for dolphins, whose presence was influenced by tidal current speed and direction. The results suggest that the conservation and management plan for this small and isolated population of bottlenose dolphins should be reviewed to adapt it to current knowledge, especially regarding the uncertainty around the potential impacts of offshore renewable energy developments off the east coast of Scotland
J.D. Manning: The Life of a WWII Draftee
No full textabstract: The biography of J.D. Manning tells the story of the first man drafted in the United States at the dawn of World War II. Growing up, he lived an ordinary, small-town life in Washburn, Wisconsin. However, due to a clerical error, by the time he was inducted into the military, J.D. had assumed a second identity. While listed under a different name throughout his military service, J.D. decided to turn the military into a career. He extended his service and went on to Officer Candidate School before serving in the war. Ultimately, J.D. died in the Battle of Cherbourg. His story outlines the importance of humanizing war at a time when statistics and numbers tend to impersonalize such a large, historical event. J.D.'s biography provides an understanding of how even the most ordinary, typical life of a drafted solider during WWII can produce an extraordinary story. J.D. was not special. He was but one death in a body count of over 400,000 American soldiers during the war. Yet, his story teaches us that one does not have to be special to be important. Every American soldier has made a contribution to our country, yet only a select few have ever had their stories told. This biography of J.D. will add one more story to the limited collection existing today
Depolarization and decreased surface expression of K+ channels contribute to NSAID-inhibition of intestinal restitution
No full textNon-steroidal anti-inflammatory drugs (NSAIDs) contribute to gastrointestinal ulcer formation by inhibiting epithelial cell migration and mucosal restitution; however, the drug-affected signaling pathways are poorly defined. We investigated whether NSAID inhibition of intestinal epithelial migration is associated with depletion of intracellular polyamines, depolarization of membrane potential (Em) and altered surface expression of K+ channels. Epithelial cell migration in response to the wounding of confluent IEC-6 and IEC-Cdx2 monolayers was reduced by indomethacin (100μM), phenylbutazone (100μM) and NS-398 (100μM) but not by SC-560 (1μM). NSAID-inhibition of intestinal cell migration was not associated with depletion of intracellular polyamines. Treatment of IEC-6 and IEC-Cdx2 cells with indomethacin, phenylbutazone and NS-398 induced significant depolarization of Em, whereas treatment with SC-560 had no effect on Em. The Em of IEC-Cdx2 cells was: −38.5±1.8mV under control conditions; −35.9±1.6mV after treatment with SC-560; −18.8±1.2mV after treatment with indomethacin; and −23.7±1.4mV after treatment with NS-398. Whereas SC-560 had no significant effects on the total cellular expression of Kv1.4 channel protein, indomethacin and NS-398 decreased not only the total cellular expression of Kv1.4, but also the cell surface expression of both Kv1.4 and Kv1.6 channel subunits in IEC-Cdx2. Both Kv1.4 and Kv1.6 channel proteins were immunoprecipitated by Kv1.4 antibody from IEC-Cdx2 lysates, indicating that these subunits co-assemble to form heteromeric Kv channels. These results suggest that NSAID inhibition of epithelial cell migration is independent of polyamine-depletion, and is associated with depolarization of Em and decreased surface expression of heteromeric Kv1 channels.ID: S0006295207001931; M3: Article; Accession Number: S0006295207001931; Author: L.C.

L'usage du narratif dans le Testament de Joseph
No full text(Résumé de l'ouvrage) Seventeen innovative studies are collected in this volume which has been produced under the aegis of the Centre for Biblical Studies, University of Manchester, and L'Institut des sciences bibliques, Université de Lausanne. The majority of the studies engage with narrative through providing insightful working examples. Building on the many contributions of recent narratological research, for the most part the studies in this collection avoid the technical language of narratology as they present fresh insights at many levels. Some essays focus more on the implied author, some on the implied reader or hearer, and some on the way particular messages are constructed; some of the studies consider how author, message and reader are all interconnected. There are several creative proposals for refining genre definition, from law and wisdom to gospel and apocryphal writings. Some studies highlight the way in which narratives can contain ethical, religious, and cultural messages. Sensitivity to narrative is also shown by some contributors to expose in intruing ways the redactional processes behind the final form of texts. Students of narrative in the ancient world will find much to consider in this book, and others engaged with literary studies more generally will discover that scholars of the worlds of the Bible and Late Antiquity have much to offer them
An Aerial Gamma Ray Survey of Chapelcross and its Surroundings in February 1992
No full textA short aerial gamma ray survey was conducted in the vicinity of the Chapelcross site from 4th-7th February 1992 to define existing background radiation levels, against which any future changes can be assessed. A twin engine AS 355 "Squirrel" helicopter chartered from Dollar Helicopters was used for this work. It was loaded with a 16 litre NaI gamma spectrometry system at SURRC in East Kilbride on the afternoon of 3rd February and flown to an off-site operational base at Lockerbie that evening. Over the following four days over 3500 gamma ray spectra were recorded from a main survey area of 21 x 25 km surrounding the site, and from a extension examining coastal zones up to 25 km further west. Additional NS and EW "tie lines" out to 40 km from the site were added for the purpose of future extendability.
The main survey grid, bounded by OS coordinates NY100590, NY 100800, NY 350800 and NY 350590, was surveyed in a series EW flight lines spaced apart by 500m. Survey speed and height were 120 kilometres per hour and 75 m. respectively. Gamma ray spectra were recorded every 10 seconds, interleaved with positional information collected on-line from a GPS satellite navigation system and time averaged radioaltimetry signals. 3500 spectra were recorded. The combination of line spacing and flight conditions results in a practically complete area survey with 500m spatial resolution. The same flight parameters were adopted for the western coastal extension and the tie lines. Data were recorded in continuous flight tracks through these to minimise flight times.
In addition a rapid response flight route was prepared which could be used to define arcs at 10km, 5km and 2km radii from Chapelcross in the event of a future incident. The path has been chosen to be navigable under most weather conditions, and falls within the area which has been mapped for baseline purposes. A survey aircraft arriving from East Kilbride could perform such a survey without pausing to refuel.
Survey results have been stored archivally and used to map the naturally occurring nuclides 40K, 214Bi, 208Tl together with 137Cs and total gamma ray flux. In interpreting the maps correctly the spatial averaging of the aerial measurements and the contouring process should be taken into account. This leads to a slight tendency to broaden spatial features and to reduce maximum values particularly for boundaries less than the spatial resolution (500m) of the survey. Small scale features will be underestimated. Radiation from the Chapelcross plant was readily detected at the perimeter and can be clearly seen in the gamma dose rate and 137Cs maps. In the former case direct radiation from 16N in the reactor heat exchangers and the release of 41Ar gas from the reactors is largely responsible. The 137Cs associated with the small-bore pipeline on-site was detected to the SW of the reactors. Signals from 234mPa were detected to the NE of the site, and are due to the on-site depleted uranium store in this area. These local observations are broadly consistent with expectations based on-site dosimetry measurements. Further afield the contamination of the Solway Firth, its intertidal sediments and adjacent tide washed pastures by 137Cs is readily detectable, and the distribution visible on the radiometric maps. This is attributed for the most part to past marine discharges from Sellafield. The most extensively affected areas were near Kirconnel in the Nith, at Caerlaverock, Rockcliffe and Burgh marshes. Smaller areas of local enhancement occur close to the tidal limits of most rivers, notably the Southwick burn, Kirkbean Glen, Burnfoot, the river Annan, the Kirtle Water and river Sark. Terrestrial levels of 137Cs vary from those associated with weapons testing fallout (2-4 kBq m-2) which occur in the main survey area, and the edge of the area contaminated from the Chernobyl accident where levels above 10 kBq m-2 are observed in the western extremities of this survey. Previous SURRC surveys have shown that this component is up to 3-4 times higher further to the West.
The natural radionuclides (40K, 214Bi, 208Tl) show variations which reflect the local subsoil geology and surface geomorphology. Prominent features include the eastern edge of the Criffel pluton, Triassic shales are responsible for enhanced levels to the east of the Nith Valley, adjacent negative anomalies are associated with Silurian outcrops to the NE of the Lochar water. Carboniferous limestones and permian sandstones are responsible for the majority of the main survey grid. Natural sources in this survey zone define a relatively low natural background level, against which local signals close to the reactor site and deposited activity on tide washed pastures produce distinct enhancements. Radiation levels at Chapelcross site fall off rapidly with distance from the perimeter, approaching natural levels within approximately 0.5-1 km at the time of the survey. Those from the marine, estuarine and tide washed environments are mostly attributed to past Sellafield discharges. Further ground based investigation of these features would be desirable
