Subglacial bed properties from normal-incidence seismic reflection data

first_imgRecent applications of the normal-incidence seismic reflection technique to studying subglacial conditions are summarized. Some of the important aspects of the technique are discussed, including critical acquisition parameters and particular strengths and weaknesses. The main reason for deploying this technique, rather than other seismic methods, is that data acquisition is simpler and requires fewer resources. Current limitations of the technique include the inability to determine subglacial seismic velocities, uncertainty in the attenuation coefficient for ice, and assumptions of source repeatability. The reflection coefficient at the ice-bed interface is calculated from the energy reduction between primary and multiple reflections. From this, the acoustic impedance of the bed is derived and used to interpret the bed material. Beneath fast-flowing ice, dilatant, deforming sediment has been distinguished from a lodged sediment bed, using porosity as a proxy for sediment dilation. Subglacial water and permafrost have also been interpreted. Data from a number of locations can be used to develop a model of the basal conditions of a complete glacier. Results from sites on ice streams in West Antarctica show how the ice encounters a greater or lesser restraint to flow, from different basal conditions. Application to a glacier in the Arctic, suggests its most recent surge terminated when water escaped through discontinuous permafrost beneath the ice. Further glaciological questions that could be addressed using the technique are proposed.last_img read more

USA: New MA Apprenticeships on the Horizon

This includes the skill areas of maintenance, inventory, safety, security, issuing and receiving of these items.The Criminal Investigator Apprenticeship (CIA) is CENSECFOR’s newest project with the United Services Military Apprenticeship Program (USMAP).“This is a coordinated effort by CENSECFOR with the Naval Criminal Investigative Service (NCIS); the MA/NSF Community Sponsor; Type Commanders; and fleet subject matter experts,” said Bautista.The apprenticeship is designed for MA personnel having the military police investigator NEC 2002, as well as appropriate personnel in the USMC and USCG. “We are in the process of soliciting industry sponsors, which could take between 4-6 months,” said Bautista. “That means we are looking at the CIA becoming available sometime in 2013.”The forerunners to these two new apprenticeships have been highly successful since their debut. For example, the Security Specialist and the Police Officer I (Government Service) apprenticeships have some 1600 active enrollments each to date. “Sailors who earn these nationally recognized certifications will have had the opportunity to perform duties and gain experiences they may not otherwise have had,” said Bautista.The USMAP works closely with the DOL to provide nationally recognized apprenticeship programs that result in journeyman-level certificates of completion for members of the U.S. Navy, Marine Corps and Coast Guard.The Center for Security Forces provides specialized training to more than 22,000 students each year and has 14 training locations throughout the U.S. and around the world.[mappress]Naval Today Staff, August 20, 2012; Image: US Navy August 20, 2012 View post tag: ON View post tag: Naval View post tag: the Share this articlelast_img read more

HSwMS Carlskrona Conducts Medical Evacuation Exercise

When operating far away from hospitals and other necessary resources, the ships in the operation need to rely on the medical competence at sea.The Swedish warship HSwMS Carlskrona has a “Role 2LM” medical capacity. This means that the ship has the capability to perform stabilising surgery, damage control and perform intensive care for 2-3 patients, for up to 72 hours. There are 4 senior doctors and 7 nurses serving within the ship’s medical department.Earlier this month, HMS Carlskrona conducted an exercise practising a medical evacuation whilst at sea. One member of the ship’s company played the part of a sailor who had fallen badly, causing a broken pelvic bone with extensive bleeding inside the abdomen.After two days, once the patient is sufficiently stable, the decision is taken to move the patient to a hospital ashore for further care and rehabilitation. The medical department prepares the patient, and many of Carlskrona’s crew lend a helping hand to move the patient to the helicopter deck where the ship’s helicopter is waiting.“This time it was just an exercise. It is important to practice the organisation so that it works when, and if, it becomes a reality”, says Åke Karlbom, senior medical officer onboard HMS Carlskrona.[mappress]Naval Today Staff, April 23, 2013; Image: EU Navfor View post tag: News by topic View post tag: Exercise View post tag: HSwMS View post tag: Evacuation Back to overview,Home naval-today HSwMS Carlskrona Conducts Medical Evacuation Exercise View post tag: Navy View post tag: conducts Share this articlelast_img read more

Postgraduate access schemes to reach under-represented backgrounds

first_imgThis summer, more than 60 paid research internships will be available through the University’s graduate access programmes. They are offering projects in a wide range of subjects from physics, biochemistry and mathematics to geography and English literature. Feedback from the pilot year of UNIQ+ was “highly positive”, and this year the programmes have expanded. Following the success of the first UNIQ+ graduate access summer school, applications for UNIQ+ 2020 and the Wellcome Biomedical Vacation Scholarships are now open. Participants are paid around £2,500 and offered free accommodation provided by Oxford colleges for the seven-week science programme or four-week humanities programme. Nadia Pollini, Director of Graduate Admissions and Recruitment, said: “We have been delighted with the success of UNIQ+ in its first year and we are very excited to have the enthusiastic support of the University, its colleges and academic departments and institutes in expanding the programme this year. We strongly encourage anyone who might benefit from such an opportunity to look into what these programmes offer to students from under-represented backgrounds.” 60 places will be available for 2020 UNIQ+. This includes six projects in biomedical sciences funded through the Wellcome Biomedical Vacation Scholarship. This year, these two programmes will offer twice as many UK students from under-represented groups the opportunity to experience postgraduate research through fully paid research internships, it has been announced. The courses are open to those who would otherwise be prevented from pursuing postgraduate study because of socio-economic, or financial circumstances. David Gavaghan, Professor of Computational Biology and Director of the MPLS Graduate School, said: “The University’s success derives from its community of outstanding researchers and the world-leading research environment that supports them. We are really excited to be able to invite students from under-represented backgrounds to join this community for the summer and to experience this world-leading environment through UNIQ+. There is no typical Oxford experience or typical Oxford student. We want everyone who could benefit from our doctoral research programmes to consider us.” Oxford University has expanded its postgraduate access scheme to reach students from underrepresented backgrounds. UNIQ+ 2019 participant and University of Bristol student, Ellie Jarvis, said: “UNIQ+ was a unique insight into postgraduate life and a really valuable way to spend the summer; it pushes you out of your comfort zone and into a worldrenowned university that is often seen as inaccessible. In 2019, 33 students from across the UK attending UNIQ+. The University’s graduate access programmes offer opportunities for graduate students to undertake a research internship under the supervision of Oxford academics and with mentoring from current students. “Opportunities like this are still scarce but I am hopeful that this is changing. I believe that the University of Oxford’s UNIQ+ programme is pioneering a new era of research internship opportunities across universities so that all students can fulfil their passions.” Participants will attend a range of skills sessions, lectures and social events, as well as receiving information on the application process for graduate study and funding. In a statement, Oxford University said: “The University is committed to giving talented applicants of all backgrounds the chance to benefit from an Oxford education, regardless of their personal circumstances. Through initiatives like UNIQ+ the University of Oxford aims to increase the number of promising graduates from under-represented groups.”last_img read more

NA struggles as membership falls

first_imgPROBLEMS caused by the NA’s declining membership were highlighted at the conference. Chairman Noel Grout told delegates the NA currently has 804 members, down 51 on the same time last year. The NA is weighing up the future of its bakery training operation due to falling demand, he said. It is currently training 91 bakers with 36 employers, down from 124 trainees last year. Mr Grout said: “The board is committed to training, but if it goes into a loss the board will pull the plug.” Training made a £19,000 profit in 2005, but Mr Grout said various running costs had not been deducted. Mr Grout also told delegates that two staff had been made redundant due to falling membership numbers. And the board will have to consider the future of its headquarters in Ware, Hertfordshire over the next year. Over the year to December 31, 2005, the NA made a £48,362 pre-tax profit, on income of £562,205.last_img read more

Reporting in

first_imgNick HarrisManaging director,BFP WholesaleThe New Year is the time to reflect on the last 12 months and look forward to the coming year. Who would have predicted that, despite all of the economic uncertainties, key bakery commodities such as fats, oils and sugar would remain as highly priced as they have done? Stocks of raw materials are at normal levels, if not slightly higher, and economic activity is slow, so surely prices should fall. Yet this was certainly not the case in 2011 and it is difficult to see any significant easing. Many commentators warned in 2007/8 that high food prices were here to stay and it certainly seems to be that way for the first part of 2012 and possibly beyond.In addition to increased raw material prices, high street and retail bakeries are suffering from a significant reduction in footfall passing their units. For some, this appears to be a challenge too far, while others are constantly looking at their offering and how this is being presented to their customers, attracting a higher proportion of those passing their doors into their shop.In times of slow economic growth, people often revert to “comfort food” and what better than a tasty freshly baked cupcake, doughnut, muffin, chocolate cake or bread offered with a freshly made hot beverage of choice? And where better to enjoy these products than the local store that makes them fresh every day, be that your bakery, coffee shop or cupcake outlet?This year sees two exciting events the Olympics and the Diamond Jubilee. Both will offer opportunities to local businesses that react to the demand they create. The independent sector is ideally placed to benefit from this demand and I wish everyone in the baking industry a successful and prosperous New Year.last_img read more

How to stop selling financial services and start selling dreams

first_img 30SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr Do you aspire to own a vacation home… or to own a second mortgage? Was your dream in life to drive a red sports car… or to have a low-interest car loan? Too many credit unions focus marketing dollars on discussing the features and product details of their credit union member services, rather than focusing on the benefits these features will provide. Yet, members aren’t looking for a skip-a-payment option, they are looking for the ability to take a summer vacation. Members will act on emotion, not logic. Your credit union can paint an emotional picture for members that speaks of the hopes, dreams and financial freedom. If done correctly, this will lead them directly to your products and services that will help them live their dreams. Consider these ideas in your next marketing campaign:Old way: “We offer wedding accounts.”New way: Picture of a father looking into the eyes of his daughter with the caption: “Give your little girl the wedding she has always dreamed of.”Old way: “Check out our great interest rates on car loans”New way: Present images of a shiny sports car and a brand new minivan turning different ways on a road: “No matter which way your life turns, we can get you there in style.”Old way: “Need a loan for your next vacation?”New way: Images of sightseeing in Rome, hiking a glacier in Alaska, laying on a beach in Mexico, and exploring Hong Kong: “Dreaming of a getaway?

Long Island Sound Sicker and Healthier Than We Think, Study Reveals

first_imgSign up for our COVID-19 newsletter to stay up-to-date on the latest coronavirus news throughout New York This summer an important environmental study of Long Island Sound came out that could—and should—play a vital role in its preservation and provide a model for protecting other estuaries around the world. The findings surprised even the scientists working on the research, myself included. They underscore the remarkable opportunities and challenges affecting the Sound.I’ve studied estuaries throughout the nation and around the world, and Long Island Sound’s uniqueness not only makes it special but protects it in ways that should be more widely understood. In every other estuary—those places where freshwater meets saltwater—the head of the estuary is where the flow of freshwater is concentrated. With the Sound, the largest flow of freshwater is not at the head, New York City, but on the side near the eastern end, where the Connecticut River—the longest river in New England—discharges its waters between Old Saybrook and Old Lyme.What makes the Sound even more remarkable is that on its western end is one of the world’s most important megacities, and on its eastern end is “The Race,” where the tide races into Long Island Sound from Block Island Sound. Also notable are the contrasts between the shores of Long Island and Connecticut. Long Island is essentially a glacially deposited sandbar, while Connecticut is composed of rocky headlands divided by a series of rivers.Those differences, plus the shared dependence on the Sound, made it crucial to have organizations and individuals from both sides of the Sound engaged in the research—through funders, agencies collecting data and citizen scientists.The Long Island Sound Report Card was funded by the Long Island Sound Funders Collaborative and created by the University of Maryland Center for Environmental Science, where I oversaw the scientific synthesis. It is the result of collaboration—not only among funders but among scientific organizations on both shores of the Sound and among academic researchers and citizen scientists. That process and the report’s findings offer great hope for the Sound, which is unlike any other estuary in the world and yet can provide a reporting model for others.The Long Island Sound Funders Collaborative consists of a dozen foundations based on Long Island, in Connecticut and New York City, and beyond, convened initially by the National Fish and Wildlife Foundation. The LI-based foundations are the Long Island Community Foundation, New York Community Bank Foundation and the Rauch Foundation.Data was collected by agencies of both states as well as by the Interstate Environmental Commission and the federal government. The citizen scientists collected data on two geographic areas of particular focus: Inner Hempstead Harbor and Norwalk Harbor.We worked to build a consensus, so the report would reflect broad agreement on key findings and, therefore, convey an especially powerful and objective conclusion. What the report found was that “there is a variation from west to east of unhealthy (F) to healthy water quality (A). The Western Narrows is affected by the highly populated, suburban-urban communities surrounding New York City and scored the worst. Moving east from western Connecticut and western Long Island, the water quality improves. In the eastern Sound, the pollution is diluted by exchange with the Atlantic Ocean.”What surprised us is how quickly the water quality improves as you move from west to east. Before you even lose sight of the Manhattan skyline, the pollution has started to dissipate. That’s because of the input of freshwater along the Connecticut coast and the power of The Race. Together they flush the Sound intensively, leaving its eastern end in amazingly good shape.There’s still a lot of work ahead to improve and protect the Sound, but these findings provide reason for hope and optimism. The Sound still faces many significant challenges, but they have changed in recent decades.The Clean Water Act of 1972 and the Clean Air Act, passed in 1970 and subsequently amended, have reduced the pollution coming out of pipes: car exhausts, smokestacks, and sewers. Now we need to make progress on more diffuse sources, especially runoff from streets and other hard surfaces, residential landscapes and agriculture.Long Island soil is very sandy, and water flows readily through it, carrying toxics from septic systems and agriculture. Septic systems clean up household waste but do not remove nutrients, like excessive nitrogen, which cause pollution.New York City needs to focus more on the runoff associated with both storm water and rainwater. The hardening of urban surfaces makes it very easy for runoff to reach the Sound.Connecticut faces challenges reflecting its coastal mix of cities and towns. Its shore also has a huge industrial legacy from past manufacturing that is disturbed when storms disrupt underwater sediment.The Long Island Sound Report Card offers a collaborative model and a set of findings that enable the tracking of combined efforts at conservation. In doing so, it adds significant value to other crucial environmental work being conducted around the Sound. It also provides a basis for collective improvement of one of the best-known estuaries in the world and could become a model for enhancing estuaries affected by the growth of 21st-century megacities.William Dennison is Vice President for Science Applications and Professor at the University of Maryland Center for Environmental Science.last_img read more

GAO says tighter security needed at two BSL-4 labs

first_img Though the CDC’s Select Agent regulations don’t specify the perimeter controls needed for BSL-4 labs, the school said it has added numerous additional security controls since the GAO’s assessment and that it is aggressively addressing the remaining issues. HHS asked the GAO to address if the 15 security controls it used were research-based. The GAO responded that it has used the security survey in the past and that though the list doesn’t represent the only measures that provide perimeter security, it does reflect “common-sense security measures.” In a response that accompanies the GAO report, the US Department of Health and Human Services (HHS) wrote that security measures at the labs have been based on risk assessments for each facility and are structured more as performance objectives than as compliance rules. Oct 18 Georgia State University statement on GAO findings Oct 16 GAO report on BSL 4 lab perimeter safety The GAO released its findings on Oct 16 in a 20-page report posted on its Web site. The agency prepared the report at the request of House of Representatives committees that have been probing safety problems at the nation’s biodefense labs. Three labs had nearly all of the security controls in place, but one had only four and another had three the controls. Investigators noted that the three labs with the tightest security were subject to additional federal security measures required by other agencies that own or control the labs. “Even though the GAO report addresses perimeter security, GSU has had multiple layers of interior security actively implemented since the inception of the laboratory,” the school said in its statement. Rep. John Dingell, D-Mich., said in an Oct 16 press release from the House Committee on Energy and Commerce that the GAO report confirms that legislators have reason to be concerned about the security of the labs that handle some of the world’s most lethal pathogens. GAO investigators conducted site visits at the labs using a survey that focused on 15 perimeter controls that they said represent a baseline for security at BSL-4 labs. Examples of the controls included barriers to prevent vehicles from approaching the lab, closed-circuit television monitoring, and armed guards at entrances. See also: Meanwhile, Kenneth Trevett, president of the lab in San Antonio, said the facility has already launched an initiative to study perimeter security, according to the AP report. “We’re waiting for additional input, but we’re not waiting too long. The GAO would like us to do some fairly significant things,” he said. “They would like us to do it sooner rather than later.” “I urge the CDC to quickly identify all security shortcomings at these facilities and determine how to best rectify the problems,” said Dingell, who chairs the House committee. “Six more of these high-containment labs are currently under construction. Once again, I urge the President to suspend the design and construction of these labs until we solve the security problems at the labs we already have.” The GAO did not name the labs because of security concerns. However, the Associated Press (AP) in an Oct 16 report said the two labs that scored low on the GAO’s security assessment are at the Southwest Foundation for Biomedical Research, a private facility in San Antonio, Tex., and at Georgia State University (GSU) in Atlanta. HHS said the CDC, along with the US Department of Agriculture, will consult with security experts and the research community to determine what perimeter enhancements are needed at the BSL-4 labs. “The CDC is committed to enhancing security at our nation’s BSL-4 laboratories based on risk and sound science, while balancing security enhancements against any impact on the important research being conducted by these laboratories,” HHS wrote in its response. In the report, the GAO recommended that the US Centers for Disease Control and Prevention (CDC) implement specific perimeter security controls for all of the country’s BSL-4 labs. Currently, the CDC’s Select Agent regulations don’t specify the perimeter controls that should be in place at the labs, which has resulted in varying security levels among the BSL-4 labs, the report said. Oct 22, 2008 (CIDRAP News) – Two of the nation’s five biosafety level 4 (BSL-4) labs lack outer-ring security controls to protect against a terrorist attack or theft of some of the world’s most dangerous pathogens, such as the Ebola and smallpox viruses, according to a new report from the Governmental Accountability Office (GAO). Oct 4, 2007, CIDRAP News story “House committee airs safety concerns about biodefense labs” Researchers at the BSL-4 lab at Georgia State University are investigating B virus, a benign herpesvirus in macaque monkeys that can cause an occupationally acquired human disease that can be fatal without prompt diagnosis and treatment, according to an Oct 18 statement from the school.last_img read more
