Drilling into Chicxulub's formation The Chicxulub impact crater, known for its link to the demise of dinosaurs, also provides an opportunity study rocks from a large structure. Large craters have “peak rings” that define complex crater morphology. Morgan et al. looked at drilling expedition through peak rings (see Perspective by Barton). drill cores features consistent with model postulates single over-heightened central collapsed multiple-peak-ring validity this has implications far-ranging...
Abstract For a long time global paleodust numerical simulations have greatly underestimated dust sources other than modern deserts. Recent modeling experiments incorporating glaciogenic of positively improved the agreement between model and data. This highlights importance accurately representing all areas potentially subjected to deflation during an investigated interval. Geochemical results, obtained from European loess sequences collected along 50°N transect, combined with emission reveal...
The erosional morphology preserved at the sea bed in eastern English Channel dominantly records denudation of continental shelf by fluvial processes over multiple glacial-interglacial sea-level cycles rather than catastrophic flooding through Straits Dover during mid-Quaternary. Here, integration multibeam bathymetry and shallow sub-bottom 2D seismic reflection profiles calibrated with vibrocore records, first stratigraphic model erosion deposition on is presented. Published Optical...
The Celtic Sea contains the world's largest continental shelf sediment ridges. These megaridges were initially interpreted as tidal features formed during post-glacial marine transgression, but glacigenic sediments have been recovered from their flanks. We examine stratigraphy of using new decimetric-resolution geophysical data correlated to cores test hypothetical vs glacial modes formation. comprise three main units, 1) a superficial fining-upward drape that extends across above an...
High‐resolution shallow sub‐bottom seismic survey data obtained for the Dudgeon windfarm site located 50 km offshore of north Norfolk coast in southern North Sea have revealed that chalk bedrock this area is overlain by sediments deposited during Elsterian and Weichselian glacial periods. A buried N–S‐trending subglacial drainage channel (tunnel valley) filled with Swarte Bank Formation ( MIS 12) indicates maximum extent ice‐sheet margin occurred further to south. Detailed cross‐sections...
ABSTRACT Offshore stratigraphic records from the North Sea contain information to reconstruct palaeo‐ice‐sheet extent and understand sedimentary processes landscape response Pleistocene glacial–interglacial cycles. We document three major Middle Late packages over a 401‐km 2 area (Norfolk Vanguard/Boreas Wind Farm), offshore East Anglia, UK, through integration of 2D seismic, borehole cone penetration test data. The lowermost unit is predominantly fluviatile [Yarmouth Roads Formation, Marine...
Abstract. Submerged landscapes on continental shelves archive drainage networks formed during periods of sea-level lowstand. The evolution these postglacial also reveals how past climate changes affected the landscape. Ice-marginal and paraglacial low-relief topography are susceptible to reorganisation water supply, forced by ice-marginal rearrangement, precipitation temperature variations, marine inundation. A rare geological climate-driven landscape transition from (ca. 23 ka) a fully...
ABSTRACT Mesolithic settlement sites preserved on the north‐east coast of England and in south‐east Scotland drive questions about relationship between early human Holocene palaeogeography ‘Doggerland’. Palaeogeographical reconstructions before 8000 years ago have been restricted by a lack sea‐level index points particularly sparse nearshore geophysical geological datasets required for such reconstructions. This paper presents new high‐resolution survey data from Northumberland's ‘white...
Abstract Low‐relief coastal landscapes are at major risk of rising sea levels, as vertical changes in relative level have far‐reaching lateral effects. Integration a dense 2D grid seismic reflection data with sedimentological and geotechnical obtained two offshore wind farm zones allows detailed documentation postglacial landforms environmental change over 1,021 km 2 area the western sector southern North Sea. Following retreat Last Glacial Maximum ice sheets from Sea, resulting terrestrial...
Abstract. Expedition 364 was a joint IODP and ICDP mission-specific platform (MSP) expedition to explore the Chicxulub impact crater buried below surface of Yucatán continental shelf seafloor. In April May 2016, this drilled single borehole at Site M0077 into crater's peak ring. Excellent quality cores were recovered from ∼505 ∼1335 m seafloor (m b.s.f.), high-resolution open hole logs acquired between total drill depth. Downhole are used image wall, measure physical properties rocks that...
