Estimating Geostrophic Shear from Seismic Images of Oceanic Structure*
No full textIt is shown that geostrophic vertical shear estimates can be recovered from seismic (i.e., acoustic) images of thermohaline structure. In the Southern Ocean, the Antarctic Circumpolar Current forms a loop within the Falkland Trough before it flows northward into the Argentine Basin. Seismic profiles that cross this loop show the detailed structure of different water masses with a horizontal resolution of O(10 m). Coherent seismic reflections are tilted in response to current flow around the Falkland Trough. Average slopes were measured on length scales that are large enough to ensure that the geostrophic approximation is valid (i.e., with a Rossby number <0.1). By combining shear estimates with satellite altimetric measurements and acoustic Doppler current profiles, geostrophic velocities can be calculated throughout the data volume. This technique for estimating geostrophic vertical shear from legacy seismic images yields useful information about the spatial and temporal variation of mesoscale circulation
Calibrated seismic imaging of eddy-dominated warm-water transport across the Bellingshausen Sea, Southern Ocean
No full textSeismic reflection images of thermohaline circulation from the Bellingshausen Sea, adjacent to the West Antarctica Peninsula, were acquired during February 2015. This survey shows that bright reflectivity occurs throughout the upper 300 m. By calibrating these seismic images with coeval hydrographic measurements, intrusion of warm water features onto the continental shelf at Marguerite and Belgica Troughs is identified and characterized. These features have distinctive lens‐shaped patterns of reflectivity with lengths of 0.75–11.00 km and thicknesses of 100–150 m, suggesting that they are small mesoscale to submesoscale eddies. Abundant eddies are observed along a transect that crosses Belgica Trough. Near Alexander Island Drift, a large, of order urn:x-wiley:21699275:media:jgrc22803:jgrc22803-math-0001 km3, bowl‐like feature, that may represent an anticyclonic Taylor column, is imaged on a pair of orthogonal images. A modified iterative procedure is used to convert seismic imagery into maps of temperature that enable the number and size of eddies being transported onto the shelf to be quantified. Finally, analysis of prestack shot records suggests that these eddies are advecting southward at speeds of urn:x-wiley:21699275:media:jgrc22803:jgrc22803-math-0002 m s−1, consistent with limited legacy hydrographic measurements. Concentration of observed eddies south of the Southern Antarctic Circumpolar Current Front implies they represent both a dominant, and a long‐lived, mechanism of warm‐water transport, especially across Belgica Trough. Our observations suggest that previous estimates of eddy frequency may have been underestimated by up to 1 order of magnitude, which has significant implications for calculations of ice mass loss on the shelf of the West Antarctic Peninsula
Seismic imaging of a large horizontal vortex at abyssal depths beneath the Sub-Antarctic Front
No full textThe global ocean and climate systems are strongly influenced by physical oceanographic processess within the Southern Ocean1. In particular, the exchange of water between subtropical North Atlantic Deep Water and the Antarctic Circumpolar Current controls the rate at which the latter upwells and mixes2. Despite its significance, the details of this exchange are poorly understood. Acoustic imaging of the water column can reveal the detailed thermohaline structure3. Here we present a subsurface acoustic image, acquired in October 1998, that crosses the Sub-Antarctic Front in the South Atlantic Ocean, where the two water masses converge and shear past each other. We find that down to a depth of 2.5?km, the vertical boundary between the North Atlantic Deep Water and the Antarctic Circumpolar Current is sharp and mass exchange is negligible. Below this depth, where cross-track velocities converge, we detect a prominent swirling structure that is 500 m high and 10?km wide. We analyse prestack acoustic records, which suggest that this structure rotates at an average speed of 0.3±0.1?m?s?1 about a horizontal axis. We suggest that the structure could either be a thermohaline intrusion created by frontal instability processes, or—more speculatively—a localized and intermittent overturning even
La Cassazione si pronuncia sull'esatta portata della fattispecie di "denuncia di un sinistro non accaduto" di cui all'art. 642 c.p.
No full textNella prima parte della nota, l’Autore analizza la fattispecie di «denuncia di un sinistro non accaduto» di cui all’art. 642, comma 2, c.p., introdotta nel 2002 nell’ambito della riforma delle assicurazioni R.C. Auto, per, poi, affrontare la questione su cui si è pronunciata la Corte di cassazione, relativa al significato da attribuire al concetto di “sinistro”. Infine, l’Autore offre le proprie riflessioni sui rapporti intercorrenti tra la fattispecie esaminata e le altre ipotesi delittuose previste dall’art. 642 c.p. e sulla compatibilità di tali reati con il principio di offensività.In the first part of the note, the Author analyzes the crime of “denunciation of a false accident” that was introduced into the art. 642 c.p. in 2002, and, then, the question about the meaning of “sinistro” (accident) on which the Supreme Court stated. Finally, the Author offers his own reflections on the connection between the examinated crime and other felonies provided under art. 642 c.p., and, also, on compatibility of those crimes with the principle of seriousness of the offense

Suspended graphene beams with tunable gap for squeeze-film pressure sensing
No full textWe present suspended graphene pressure sensors fabricated using an innovative surface micro-machining process. The great advantage of this process is that the molybdenum (Mo) catalyst layer for multi-layer graphene chemical vapor deposition (CVD) is also used as a sacrificial layer to suspend the graphene. This method allows for accurate control of the gap size under the beam by simply varying the catalyst thickness. Furthermore, the need for transfer of the graphene layer is eliminated. Using this method, wafer-scale graphene squeeze-film pressure sensors are fabricated and characterized.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic Components, Technology and MaterialsQN/Steeneken LabQN/van der Zant LabDynamics of Micro and Nano System
2021 butterfly inventories within Boulder County open spaces, Boulder, Colorado
No full textApril 4, 2022.Includes bibliographical references.The butterfly inventories continued for the 18th year in a few of the Boulder County Open Space properties. However, because of the Calwood Fire during October 17, 2020, two of the survey areas were inaccessible; Plumely Canyon and the work road through the streamlet near the Lichen Trail. Geer Watershed had been burned, but the meadows above the Resident Ranger's Cabin and associated streamlets were made accessible with our 2021 permit. Cabbage Whites (Pieris rapae), Orange Sulphurs (Colias eurytheme) and Common Wood-nymphs (Cercyonis pegala) were more numerous when compared to 2015-2020 populations before the burn. In 2021 within other Open Spaces, Anne U. White and Caribou, the resident species produced noticeably large populations: Julia Orangetips (Anthocharis julia), Pine Whites (Neophasia menapia), Northern Checkerspots (Chlosyne palla), Common Wood-nymphs, Small Wood-nymphs (C. oetus), Common Checkered-skippers (Burnsius communis). On the other hand, the well adapted non- native Cabbage Whites were again the most common during the long season; Variegated Fritillaries (Euptoieta claudia) and Dainty Sulphurs (Nathalis iole) were numerous flying in from colonies in the eastern plains and low foothills where their host plants were plentiful. 95 species were seen in 2021: 129 species between 2004 and 2021 in the county Open Spaces. 203 species are on the record for Boulder County (Butterflies and Moths of America 2021) website. The average number of species per year observed within the Open Spaces by this team is 88
