Abstract Variations in chalcophile and redox‐sensitive trace elements are examined at high‐resolution intervals from a ~50 kyr long sediment core (MD02‐2496) the Vancouver Island margin. Enrichments of Ag, Cd, Re, U, Mo above lithogenous levels, signifying sedimentary suboxia anoxia, occurred during early Holocene Bølling/Allerød, warm interstadial events Marine Isotope Stage (MIS) 3. Down‐core element profiles co‐vary with productivity proxy records (opal, CaCO 3 , marine organic carbon),...

Distinctive nonlaminated intervals we term speckled beds (SBs) are common in finely laminated diatomites of the Monterey Formation at Celite Quarry, Lompoc, California. SBs have sharp and bedding-parallel upper lower contacts, tabular geometry, less than or equal to 10 cm thick. characterized by a arrangement sand- granule-size diatomaceous detrital aggregates that uniformly distributed fine-grained matrix macerated biosilica mud. The unique physical properties sediments provided cohesive...
Multiproxy analysis of a 38 m long sediment core recovered from the Vancouver Island margin (48.97°N, 127.04°W, water depth 1243 m) has yielded millennial-scale history upwelling and export production over last ∼50 ka. Higher concentrations marine organic carbon, opal, trace Mo suggest that was higher, sedimentary pore waters more anoxic, during warm Holocene, Bølling–Allerød, interstadial events between 31 44 ka BP. Relatively lower higher inputs terrigenous matter occurred glacial (14.7–31...
Abstract A high‐resolution, 55 kyr long record of chalcophile and redox‐sensitive trace element accumulation (Ag, Cd, Re, Mo) from MD02‐2515, western Guaymas Basin, is investigated in conjunction with patterns stratigraphy productivity. High opal concentrations (~59 wt. %), representing increased diatom production, coincide laminated sediments dilute the organic carbon (C org ) metals. similarity between normalized C , Ag, Cd suggests delivery to by export while Re Mo suggest a different...
Both mountain pine beetle (MPB) Dendroctonus ponderosae Hopkins and fire leave scars with similar appearance on lodgepole Pinus contorta Dougl. ex Loud. var. latifolia Engelm. that have never been compared microscopically, despite the pressing need to determine respective effects of MPB injury tree physiology. We analysed changes in wood formation naturally caused pine, tested hypotheses (i) elicit distinct anomalies (ii) differ magnitude and/or duration between fire. Mountain reduced radial...
Finely laminated diatomaceous sediments from the Miocene Monterey Formation, Lompoc, Santa Barbara County, California, record mutualistic coupling of life processes and environmental evolution at subannual subseasonal resolution. In this study we present a new classification lamina couplet styles based on bimodality, thickness, compositional domination, spacing, cyclicity. We also describe five distinct types with emphasis paleoenvironmental settings, paleoecological associations,...
There are many options for incision closure in forefoot surgery. The aim of this study was to compare topical skin adhesive (2-octyl-cyanoacrylate) simple interrupted nylon sutures.A prospective randomized controlled trial comparing (TSA) and sutures (NSs) elective open Primary outcome Hollander Wound Evaluation Scale (HWES) assessed 2 weeks following Secondary objectives included time taken wound closure, assessment, patient satisfaction with cosmesis, pain, infection rate.Between January...
