Late Glacial history of the Ross Sea sector of the West Antarctic Ice Sheet: evidence from englacial layering at Talos Dome, East Antarctica

first_imgThe timing of West Antarctic Ice Sheet (WAIS) expansion and retreat during the last glacial cycle is crucial to evaluating the processes controlling ice sheet fluctuations. There is currently debate as to whether grounded ice across what is now the Ross Ice Shelf decayed during the early Holocene or at a time coincident with meltwater pulse 1a. Here we show, from analysis of englacial radio-echo layering across Talos Dome in Oates Land, East Antarctica, that the pattern of snowfall has been relatively consistent for the past 8,000–10,000 years. This was preceded by a transition from glacial maximum-type accumulation at between 10,000 and 20,000 years. We interpret glacial maximum accumulation rates to correspond with the expansion of the grounded WAIS across the Ross shelf, so preventing storm tracks from accessing Victoria Land as they do today (as identified previously at Taylor Dome). The return to modern-type accumulation after 8,000 years is consistent with geological evidence for WAIS retreat. No large-scale alteration in accumulation is observed around 14,000 years ago, during the time of meltwater pulse 1a.last_img read more

A multi-wavelength classification method for polar stratospheric cloud types using infrared limb spectra

first_imgThe Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) instrument on board the ESA Envisat satellite operated from July 2002 until April 2012. The infrared limb emission measurements represent a unique dataset of daytime and night-time observations of polar stratospheric clouds (PSCs) up to both poles. Cloud detection sensitivity is comparable to space-borne lidars, and it is possible to classify different cloud types from the spectral measurements in different atmospheric windows regions. Here we present a new infrared PSC classification scheme based on the combination of a well-established two-colour ratio method and multiple 2-D brightness temperature difference probability density functions. The method is a simple probabilistic classifier based on Bayes’ theorem with a strong independence assumption. The method has been tested in conjunction with a database of radiative transfer model calculations of realistic PSC particle size distributions, geometries, and composition. The Bayesian classifier distinguishes between solid particles of ice and nitric acid trihydrate (NAT), as well as liquid droplets of super-cooled ternary solution (STS). The classification results are compared to coincident measurements from the space-borne lidar Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument over the temporal overlap of both satellite missions (June 2006–March 2012). Both datasets show a good agreement for the specific PSC classes, although the viewing geometries and the vertical and horizontal resolution are quite different. Discrepancies are observed between the CALIOP and the MIPAS ice class. The Bayesian classifier for MIPAS identifies substantially more ice clouds in the Southern Hemisphere polar vortex than CALIOP. This disagreement is attributed in part to the difference in the sensitivity on mixed-type clouds. Ice seems to dominate the spectral behaviour in the limb infrared spectra and may cause an overestimation in ice occurrence compared to the real fraction of ice within the PSC area in the polar vortex. The entire MIPAS measurement period was processed with the new classification approach. Examples like the detection of the Antarctic NAT belt during early winter, and its possible link to mountain wave events over the Antarctic Peninsula, which are observed by the Atmospheric Infrared Sounder (AIRS) instrument, highlight the importance of a climatology of 9 Southern Hemisphere and 10 Northern Hemisphere winters in total. The new dataset is valuable both for detailed process studies, and for comparisons with and improvements of the PSC parameterizations used in chemistry transport and climate models.last_img read more

Is Hunters the most gender balanced estate agency in the UK?

first_imgHunters has released figures showing it is one of the most gender-balanced estate agency in the UK, ahead of International Women’s Day on Sunday.This includes how just over 60% its 680 staff members are female including both directors, heads of department and other key decision-making roles.Hunters also says 28 of its franchise directors across its network are female, which the company says has played a key role in its success.Hunters, which was established in 1992 by Kevin Hollinrake, is also the only PLC in the sector to have a female CEO, Glynis Frew, (pictured, above, centre).The only other woman to make it to the top of the corporate ladder in the property PLC world in recent times has been Alison Platt.Female representation“It is great to see industry female representation continue to grow and we’re proud that Hunters, along with many others in property, have been encouraging it for some time now,” says Frew.“More and more women entering the industry can only be a good thing but we must not forget that the value of the contribution to our fantastic industry is not gender-dependent.“Whilst the importance of female representation cannot be overlooked, it is also important to stress that recruitment is about getting the right person for the job and there should be no sense of discrimination at any level.”Hunters does not publish a Gender Pay Gap as it has fewer than 1,000 staff  but many of its larger competitors do.Countrywide estate agency business, for example, reports a gender pay gap of 29.5%, much higher than the national average of 11.9% and higher than Connells (23%), Sequence and Your Move (24%) and Foxtons (25.5%). But all these beat Savills, where the pay gap is 43%.Read more about the gender pay gap.Find out more about International Womens’ Day.Glynis Frew Hunters connells Countrywide Foxtons March 4, 2020Nigel LewisOne commentJulian Blackmore, BNE BNE 4th March 2020 at 9:13 amIf you’re good at your job what difference does it make if your male or female?; particularly in the property industry.

Rout sends Oxford up to cloud nine

first_imgOxford 9 – 1 LeicesterAS THE dark clouds of October descended over Iffley Road, it seemed only the glaring pink jerseys of the two umpires could brighten up a gloomy afternoon. Anyone who witnessed the opening exchanges could be forgiven for agreeing. Both sides managed to string a few passes together only for a poor touch, a foot or good honest defence to see the move break down. Early signs indicated that chances could be few and far between. But the Blues could be excused for not being at their most enthusiastic. Having to trudge through the depths of the BUSA pyramid can be tedious, especially as games are often an unwelcome distraction from Southern Premier League fixtures that are played at weekends. After a 3-2 loss to Richmond on Saturday, Oxford will face Staines in their next non-BUSA fixture.The scrappy opening was brought to an abrupt halt by a freak injury. On ten minutes David Cresswell tried to turn in Leicester’s  ‘D’, raising his stick to strike the ball but succeeding only in finding contact with a Leicester player’s head, leading to an ambulance call disrupting the flow of the game.After the stoppage, the gulf in class between the two sides was suddenly there for all to see. The Leicester goal was now under siege, the Blues surging forward, making darting runs and finally asking a few questions of the Leicester stopper.Oxford were being kept at bay, but it was only a matter of time until they broke the deadlock. In the nineteenth minute, a cross in front of the Leicester defence wasn’t dealt with properly, leaving Ivey to beat the keeper from eight metres out.The home side didn’t rest on their laurels and pressed for more, short corner after short corner coming the way of the Blues, only for their efforts to be parried away. But a second was always on the cards, and it came from another short corner. Cresswell’s shot was stopped by the keeper, but only as far as Molinari, who converted the simple tap in. A third also came from a short corner drilled in by Sibley,  but a well worked set piece by Leicester pulled one back just before the interval, following a rare foray into Oxford’s half.That goal could have been the catalyst for a Leicester comeback, but it was the Blues who came out of the blocks fastest and reasserted their dominance after the break. Martin Pickup rifled one past the keeper and Mark Kindo tapped another in after successive short corners.Short corners continued to cause havoc for the Leicester defence, Kindo profiting from one and claiming his second goal of the match. Brad Tucker added a seventh, before a late brace by Cresswell completed the rout.There can be no doubting the way Oxford approached the game, but the Blues won’t have felt stretched or challenged. For now, the real tests for the hockey players come at the weekend.last_img read more

Ocean City Chamber of Commerce – Salute to Working Women Set for April 25

first_imgThe Ocean City Regional Chamber of Commerce announces that Lynne Cates, owner of Sun Seekers Boutique, will receive the 2018 Salute to Working Women Award and will be honored at the Chamber of Commerce Luncheon on April 25th at Ocean City Yacht Club. The award recognizes women in business for their outstanding professional and personal achievements.Cates and Sun Seekers Boutique are celebrating 25 years in business in Downtown Ocean City. A summer job at Sylvia’s Boutique with Sylvia and Abe Milman, turned into a lifetime career. Cates eventually took over the buying and began running the store for the Milman’s. In 1993, upon the Milman’s retirement, Lynne and her husband purchased the business and property. The store was renamed Sun Seekers.Over the years, the changing retail environment was a challenge. Cates overcame the challenges by focusing on her buying, making frequent trips to New York, finding many unique value oriented lines, and prioritizing customer service. These efforts helped Sun Seekers develop an ever increasing loyal cliental. All this, while raising a family with her husband, Dave, owner of Piccini’s Restaurant.Additionally, the chamber will be honoring New Jersey Superintendent of the Year Kathleen Taylor, New Jersey Teacher of the Year Amy T. Andersen, and State Board of Education Representative Nora Faverzani.The luncheon will honor all working women at home or in the workforce on Wednesday, April 25th at noon at Ocean City Yacht Club. The luncheon is open to the public and is $25 per person. For more information, to make a reservation, or to place a congratulatory ad in the program book, please contact the Chamber office at 609-399-1412 or email us at [email protected]last_img read more

Consumers not seeking out organic

first_imgOnly 9% of consumers actively seek out organic product claims, with organic being ranked 27th of 34 commonly ‘looked-for’ product claims by UK shoppers.The most motivating product claims, found in the survey by MMR Research Worldwide, were ‘healthy’ and ‘low fat’, with 43% of consumers stating they actively seek out those claims when shopping for food. This is followed by ‘low in sugar’ (36%), ‘low in salt’ (34%) and ‘low in calorie’ (31%) claims. Interestingly, 25% of consumers look for ‘locally produced’ products (the 11th most appealing product claim) and 19% – more than double the positive response to organic – cited ‘Fairtrade’ as something they looked out for.  MD Mat Lintern said: “They find claims such as ‘healthy’, ‘natural’ and ‘free of artificial colours, flavours and preservatives’ – benefits clearly associated with organic food – up to five times as appealing. The implication for organic food brands is to introduce more of the benefits of organic into their messaging, instead of relying on organic alone.”last_img read more

‘Porgy and Bess,’ made new

first_img“My hope for an audience is that they come to the production and they not only talk about the great music that they all know and love, but that they are deeply moved by the story and by the characters, so that it’s an experience that is deep, and powerful and moving in all ways.” Much has been said about the American Repertory Theater’s (A.R.T.) new version of the 1935 opera “Porgy and Bess.” But as the show continues to evolve, its director prefers to keep the ever-changing details quiet, opting to let the production of “The Gershwins’ Porgy and Bess” speak for itself.“It’s been great to have so much dialogue about the production,” said A.R.T. Artistic Director Diane Paulus, who has stirred debate in the theater world with her new take on the classic work, which features music by legendary composer George Gershwin and lyrics by his brother Ira and author Dubose Heyward. “We hope people come to see it, and get involved and engage with it. That’s the goal.”Paulus collaborated with Pulitzer Prize-winning writer Suzan-Lori Parks and two-time Obie Award winner Diedre Murray to develop a new vision for the show with the approval of the Gershwin estate. The show stars four-time Tony Award winner Audra McDonald and Norm Lewis.It’s not surprising that Paulus is reimagining the legendary American folk opera set during the early 1900s in a black enclave in South Carolina with a disabled beggar and his drug-addicted love as its central characters. The director is known for infusing fresh life and energy into familiar works and engaging new generations of theatergoers with her innovative takes on live performance. In this case, the concept of reworking the show has drawn criticism from veteran composer Stephen Sondheim.But for Paulus, at the heart of the new production remains the emotional pull of the original.“We are interested in developing a deeply moving, powerful, and evocative version of this great classic,” said Paulus, who is continuing to rework the show during its run at Harvard’s A.R.T. before it moves to Broadway. “The difference is we are on a musical stage, not an operatic one, so there’s a different scale we are working in. And I am hoping that it’s not about reducing it. It’s about heightening the intensity of the experience.”Paulus also turned to another group for inspiration in the early stages of refashioning the opera into more of a musical. Last spring she co-taught a Harvard College class with Marjorie Garber, William R. Kenan Jr. Professor of English and of Visual and Environmental Studies, called “Porgy and Bess: Performance and Context.”“It was an immersion in the historical context of the piece and how it has changed over the 20th century,” said Paulus, who brought in guests such as the show’s set designer and choreographer, as well as a lawyer for the Gershwin estate, to talk to the class. The students examined the history of the piece in depth, studying everything from Heyward’s original novel to the 1959 film staring Sidney Poitier.Eager to hear what 18-year-olds thought of the piece in 2011, Paulus said the course culminated in an examination of the planning for the A.R.T. production.“The students were really in the room discussing what we were thinking of doing for the production. They were contributing to thoughts that at the time were being developed” for the show.While bringing arts into the life of the academic community is paramount for Paulus, so too is bringing her work to the community at large.“It was so important to me that a show like this … is shared with the most diverse and broadest spectrum of Boston audiences,” she said, adding, “We have made a huge effort to create access and dialogue around the production.”In that vein, hundreds of local high school students will attend performances, and many will participate in a series of educational activities and discussions with teaching artists as part of the A.R.T.’s Education Experience initiative. In addition, through its Community Connections program, the A.R.T. will offer discount tickets and workshops, classes, mentoring opportunities, and private performances to several nonprofit organizations in the Boston area.last_img read more
