    Response of a marine-terminating Greenland outlet glacier to abrupt cooling 8200 and 9300 years ago

    , Geophysical Research Letters, Vol: 38, ISSN: 0094-8276

    Long-term records of Greenland outlet-glacier change extending beyond the satellite era can inform future predictions of Greenland Ice Sheet behavior. Of particular relevance is elucidating the Greenland Ice Sheet's response to decadal-and centennial-scale climate change. Here, we reconstruct the early Holocene history of Jakobshavn Isbr, Greenland's largest outlet glacier, using <sup>10</sup>Be surface exposure ages and <sup>14</sup>C-dated lake sediments. Our chronology of ice-margin change demonstrates that Jakobshavn Isbr advanced to deposit moraines in response to abrupt cooling recorded in central Greenland ice cores ca. 8,200 and 9,300 years ago. While the rapid, dynamically aided retreat of many Greenland outlet glaciers in response to warming is well documented, these results indicate that marine-terminating outlet glaciers are also able to respond quickly to cooling. We suggest that short lag times of high ice flux margins enable a greater magnitude response of marine-terminating outlets to abrupt climate change compared to their land-terminating counterparts.

    Application of 3D seismic data to understanding the structure and stratigraphy of sedimentary basins

    , Tectonics of Sedimentary Basins: Recent Advances, Editors: Busby, Pérez, Publisher: Wiley-Blackwell, Pages: 95-110, ISBN: 9781405194655

    Although 2D seismic data are able to provide regional insights into the broad form and fill of sedimentary basins, their limited spatial resolution restricts the detailed analysis of geological features. Improvements in 3D seismic acquisition and processing techniques have resulted in large tracts of sedimentary basins being covered by high-quality surveys. The development of sophisticated software, and low-cost, high-powered workstations, allows the interpretation of these data in unprecedented detail. This chapter focuses on some of the key interpretation techniques available to the seismic interpreter, and will demonstrate how these can be used to gain an understanding of the structure and fill of sedimentary basins at a range of scales. The benefits of analysing structure and stratigraphic thickness maps are considered, as these are important for defining basin structure, and for highlighting the temporal and spatial variability of syn-depositional accommodation, tectonics and erosion. The use of ‘seismic attributes analysis’ to highlight geological features is discussed. These attributes include, amongst others, grid- and volume-based geometric attributes, and grid and volume-derived, amplitude-based attributes. Although seismic attribute analysis is a powerful tool in basin analysis, the answer to a subsurface geological problem does not lie within the workstation or the attributes that can be generated. The workstation is only a tool. The key elements involved in the successful application of seismic data to basin analysis are: (i) a knowledge of the available interpretation tools, (ii) an appreciation of the physical basis of the attributes being used, (iii) an understanding of the impact of data and interpretation quality on the derived attributes and (iv) a thoughtful geological interpretation of geophysical data. With continued improvements in spatial coverage and resolution, seismic reflection datasets have the potential to be as powerful a t

    Rates and timing of vertical-axis block rotations across the central Sierra Nevada-Walker Lane transition in the Bodie Hills, California/Nevada

    , Tectonics, Vol: 30, ISSN: 0278-7407

    We use paleomagnetic data from Tertiary volcanic rocks to address the rates and timing of vertical-axis block rotations across the central Sierra Nevada-Walker Lane transition in the Bodie Hills, California/Nevada. Samples from the Upper Miocene (∼9 Ma) Eureka Valley Tuff suggest clockwise vertical-axis block rotations between NE-striking left-lateral faults in the Bridgeport and Mono Basins. Results in the Bodie Hills suggest clockwise rotations (R ± δR, 95% confidence limits) of 74 ± 8° since Early to Middle Miocene (∼12-20 Ma), 42 ± 11° since Late Miocene (∼8-9 Ma), and 14 ± 10° since Pliocene (∼3 Ma) time with no detectable northward translation. The data are compatible with a relatively steady rotation rate of 5 ± 2° Ma<sup>-1</sup> (2σ) since the Middle Miocene over the three examined timescales. The average rotation rates have probably not varied by more than a factor of two over time spans equal to half of the total time interval. Our paleomagnetic data suggest that block rotations in the region of the Mina Deflection began prior to Late Miocene time (∼9 Ma), and perhaps since the Middle Miocene if rotation rates were relatively constant. Block rotation in the Bodie Hills is similar in age and long-term average rate to rotations in the Transverse Ranges of southern California associated with early transtensional dextral shear deformation. We speculate that the age of rotations in the Bodie Hills indicates dextral shear and strain accommodation within the central Walker Lane Belt resulting from coupling of the Pacific and North America plates.

    Fluvial reservoir analogues in the Malay Basin: analysis of shallow 3D seismic data of Pleistocene rivers on the Sunda Shelf.

    , Seismic Imaging of Depositional and Geomorphic Systems: 30th Annual GCSSEPM Foundation Annual Bob F. Perkins Research Conference Proceedings, Publisher: GCSSEPM Proceedings, Pages: 328-329

    This study focuses on the analysis of Pliocene fluvial depositional systems based on the shallow part (seabed to about 500 m) of a large (>10,000 km2), mega-merge 3D seismic dataset from the Malay Basin, Southeast Asia. The results of a detailed 3D seismic facies analysis, locally calibrated with high-resolution site survey data, will be presented. The Pliocene interval is up to approximately 500 m thick and comprises a range of seismic facies, which reflect changes in fluvial channel style and gross stratigraphic architecture. The succession has been divided into five stratigraphic units, bounded by basin-wide stratal surfaces. The expression of these fluvial systems will be illustrated in seismic sections, stratal and proportional slices, and through various 3D volume extraction displays. This will include the youngest channel complex, which forms part of a major incised valley (approximately 18 km wide and up to 90 m deep), which formed an axial drainage system along the length of the Malay Basin during the latest Pleistocene, when the whole Sunda Shelf was exposed. In other intervals, the coastal plain is characterised by a range of unconfined high- and low-sinuosity fluvial channel systems. Planform geometries and other dimensions have been documented using GIS methods in order to develop a quantitative database of the Sunda Shelf fluvial systems.These data and other observation from the Pliocene fluvial systems are being used to determine reservoir body dimensions, geometries and estimates of connectivity that will aid the interpretation of similar, fluvial reservoirs in the deeper prospective Miocene interval.

    Application of partial factors of safety in numerical analysis of bearing capacity

    , Pages: 775-781

    One of the issues that arise when using numerical analysis in accordance with Eurocode 7 is how to account for partial factors of safety on material strength. Namely, Eurocode 7 implies that strengths to be used in an analysis should be based on a design value, but reduced by partial factors. This can be done in two ways, but Eurocode 7 gives no guidance as to which one is more appropriate. This paper examines the application of partial factors of safety in a bearing capacity problem. Finite element analyses are performed using both a simple Tresca and a more advanced Modified Cam Clay models to represent soil behaviour, and both approaches for the application of partial factors of safety.

    Controls on synrift turbidite deposition on the hanging wall of the South Viking Graben, North Sea rift system, offshore Norway

    , AAPG Bulletin, Vol: 95, Pages: 1557-1587

    Three-dimensional seismic, wireline-log, core, and biostratigraphic data from the South Viking Graben, North Sea rift system, are integrated to investigate the controls on the temporal and spatial development of an Upper Jurassic synrift turbidite system deposited on the hanging-wall dipslope of a salt-influenced half graben. Turbidite deposition was coeval with the initiation and upslope (paleo-landward) migration of activity across a gravity-driven normal fault array. Three main synrift stratal units are identified, and these are mapped using seismic and well data. The lowermost unit (upper Oxfordian) comprises thick amalgamated turbidites, which are restricted to the hanging wall of the earliest, most basinward, growth fault. The middle unit (Kimmeridgian) is more areally extensive than the underlying system, draping the now inactive basinward growth fault and extending upslope into the hanging wall of a newly activated landward growth fault. The uppermost unit (lower to middle Volgian) is more sheetlike and was deposited when activity across all growth faults had mostly ceased and slope topography had been almost fully healed. This study demonstrates that hanging-wall dipslopes within rifts can be characterized by volumetrically significant, sand-rich, gravity flow-dominated depositional systems, and that the reservoir architecture of such deposits can be strongly controlled by syndepositional growth faulting. In addition, this study provides insights into the response of turbidites to tectonically driven changes in bathymetry, which may be applicable in a range of basin settings.
