Endurance Basin is an elongate broadly WNW-ESE trending basin located on the northern margin of the Scotia Sea, adjacent to the southern margin of the South Georgia micro-continent. Bathymetric and TOPAS sub-bottom profile data acquired in 2010 by the British research ship RRS James Clark Ross map this basin and its sedimentology for the first time. Endurance Basin contains a number of sub-basins and a substantial glaciogenic fan. The northern margin of Endurance Basin is formed by a series of steep slopes and intervening troughs. These are interpreted as a left-stepping en echelon array of oblique, strike-slip faults whilst the sub-basins are separated by compressional dip-slip faults. It appears that South Georgia is moving NW with respect to the basin. We interpret five seismic facies from TOPAS data, which are associated with distinct sedimentologies. The most striking units in the basin fill are: substantial contourite drifts located in the NW of the basin and on its southern margin; and two distinct mass transport deposits that pond in the centre of the basin. Combined with the known regional oceanographic setting, the contourites provide evidence of broadly eastward flowing bottom currents, entering the basin from at least two locations. Although landslide scars are present on the steep northern basin margin, the imaged mass transport deposits are interpreted to have been sourced from the glaciogenic fan, located in the SE of the basin, and from a contourite unit located on the basin’s southern margin. Sediments from these events are transported at least 40 km. The contourite drift sequence is at least 100 m thick in the west of the basin and may contain a palaeoenvironmental archive of Antarctic Cirumpolar Current (ACC) flow and the climate of South Georgia extending to the Pliocene. Such an archive would allow reconstruction of ACC flow through the Pleistocene glaciations and provide a means of linking ocean circulation and climate records in the sub-Antarctic Polar Front region.
Marine calcifiers are amongst the most vulnerable organisms to ocean acidification due to reduction in the availability of carbonate ions for skeletal/shell deposition. However, there are limited long-term studies on the possible impacts of increased pCO2 on these taxa. A 7 month CO2 perturbation experiment was performed on one of the most calcium carbonate dependent species, the Antarctic brachiopod Liothyrella uva, which inhabits the Southern Ocean where carbonate ion saturation levels are amongst the lowest on Earth. The effects of the predicted environmental conditions in 2050 and 2100 on the growth rate and ability to repair shell in L. uva were tested with four treatments; a low temperature control (0 °C, pH 7.98), a pH control (2 °C, pH 8.05), mid-century scenario (2 °C, pH 7.75) and end-century scenario (2 °C, pH 7.54). Environmental change impacts on shell repair are rarely studied, but here repair was not affected by either acidified conditions or temperature. Growth rate was also not impacted by low pH. Elevated temperature did, however, increase growth rates. The ability of L. uva to continue, and even increase shell production in warmer and acidified seawater suggests that this species can acclimate to these combined stressors and generate suitable conditions for shell growth at the site of calcification.
Proton flux measurements from the Proton Telescope instrument aboard the CRRES satellite are revisited, and used to drive a radial diffusion model of the inner proton belt at 1.1 ≤ L ≤ 1.65. Our model utilises a physics‐based evaluation of the cosmic ray albedo neutron decay (CRAND) source, and coulomb collisional loss is driven by a drift averaged density model combining results from the International Reference Ionosphere, NRLMSIS‐00 atmosphere and Radio Plasma Imager plasmasphere models, parameterised by solar activity and season. We drive our model using time‐averaged data at L = 1.65 to calculate steady state profiles of equatorial phase space density, and optimise our choice of radial diffusion coefficients based on four defining parameters to minimise the difference between model and data. This is first performed for a quiet period when the belt can be assumed to represent steady state. Additionally, we investigate fitting steady state solutions to time averages taken during active periods where the data exhibits limited deviation from steady state, demonstrated by CRRES measurements following the 24th March 1991 storm. We also discuss a way to make the optimisation process more reliable by excluding periods of variability in plasmaspheric density from any time average. Lastly, we compare our resultant diffusion coefficients to those derived via a similar process in previous work, and diffusion coefficients derived for electrons from ground and in situ observations. We find that higher diffusion coefficients are derived compared with previous work, and suggest more work is required to derive proton diffusion coefficients for different geomagnetic activity levels.

July 11, 2018 /Sports News – National Football player tweets at TSA, claiming mother’s ashes spilled during screening [email protected]/Twitter(LOS ANGELES) — New York Giants defensive lineman A.J. Francis has called out the TSA on Twitter for how it handled his luggage at Los Angeles International Airport – specifically, he says, a container with the ashes of his mother inside.But the TSA, while expressing condolences, is pushing back on his account.His tweet, full of foul language, says the next time the TSA feels “the need to go through my mother’s ashes for no reason make sure you close it back so her remains aren’t spilled on all my clothes.”Carrie Leanne Francis, who died on June 26, was only 46 years old.During the screening of Francis’s checked bag, the TSA said, video review showed an alarm was called for an unidentified object, described as an “opened, unmarked ceramic container, wrapped in aluminum foil inside a small bag.”Upon further inspection of the checked bag, the TSA said in a statement, the container was loosely packaged, unmarked and the contents were unknown to the TSA officer.After an officer completed screening of the checked bag – clearing it to continue to its destination – the container was carefully repacked and put into place, the agency said.A photo in Francis’s tweet shows clothing in his luggage covered in what he said were his mother’s ashes and a notice of inspection bag from TSA.“TSA understands how painful losing a loved one is, and we express our sincere condolences to Mr. Francis,” TSA told ABC in a statement. “TSA officers are trained to treat all travelers’ belongings with care and respect.”For passengers traveling with cremated remains through a checkpoint, TSA recommends securing them in a container made of a lighter weight material, such as wood or plastic.Copyright © 2018, ABC Radio.

March 4, 2019 /Sports News – Local Kyle Whittingham Signs Contract Extension with Utes FacebookTwitterLinkedInEmailSALT LAKE CITY—Football coach Kyle Whittingham, who led Utah to a Pac-12 South Division title and a berth in the 2018 Pac-12 Championship game, has signed a contract extension through December of 2023, Director of Athletics Mark Harlan announced today. He has enjoyed great success against Power Five conferences, producing winning records against the ACC (7-1), Big Ten (4-1), Big 12 (5-3) and SEC (1-0). The Utes have also fared well in eight years in the Pac-12, winning or sharing two Pac-12 South Division titles and registering wins against every school. The Utes appeared in every weekly College Football Playoff ranking in the first three years of the system (2014-16) and have finished in the CFP top-25 four times. In 2008, the 13-0 Utes finished No. 2 in the AP poll—one of five appearances in the final AP rankings under Whittingham. “Coach Whittingham is one of the top coaches in college football and extending his contract was a high priority in my first year here,” said Harlan. “Kyle’s teams compete for championships on the field and in the classroom, and his loyalty to the University of Utah has made this a great partnership.” Utah opens its 15th spring camp under Whittingham today. Spring practices and scrimmages are open to the public. Whittingham, the longest-tenured head coach in the Pac-12 and the third-longest tenured coach at the same school in the NCAA FBS, is preparing for his 15th season at the helm at Utah, where he boasts a 120-61 record. His 84.6% success rate in bowl games (11-2) ranks second in NCAA history and his 11 wins is tied for second among active coaches. “On behalf of our entire coaching staff, we are grateful to both Mark Harlan and President Ruth Watkins for this vote of confidence in our football program,” said Whittingham. “The University’s support is critical to our long-term success and this sends a positive message to our recruits, which are the lifeblood of any program.” Written by Whittingham came to Utah in 1994 as the defensive line coach and was promoted to defensive coordinator the next year. On December 8, 2004, he became the school’s 20th head coach. His first victory came three weeks later when he co-coached (with Urban Meyer) the 2005 Fiesta Bowl win over Pittsburgh. Tags: Kyle Whittingham/Utah Utes Football Whittingham’s teams have also achieved unprecedented success academically. Utah boasted the best NCAA Graduation Success rate of the Pac-12 football programs in the latest report and the 2018 Utes set a new school mark for fall semester GPA with a 2.925 cumulative average.
