Exploring former subglacial Hodgson Lake, Antarctica. Paper II: palaeolimnology

first_imgDirect exploration of subglacial lakes buried deep under the Antarctic Ice Sheet has yet to be achieved. However, at retreating margins of the ice sheet, there are a number of locations where former subglacial lakes are emerging from under the ice but remain perennially ice covered. One of these lakes, Hodgson Lake (72°00.549′S, 068°27.708′W) has emerged from under more than 297–465 m of glacial ice during the last few thousand years. This paper presents data from a multidisciplinary investigation of the palaeolimnology of this lake through a study of a 3.8 m sediment core extracted at a depth of 93.4 m below the ice surface. The core was dated using a combination of radiocarbon, optically stimulated luminescence, and relative palaeomagnetic intensity dating incorporated into a chronological model. Stratigraphic analyses included magnetic susceptibility, clast provenance, organic content, carbonate composition, siliceous microfossils, isotope and biogeochemical markers. Based on the chronological model we provisionally assign a well-defined magnetic polarity reversal event at ca 165 cm in the lake sediments to the Mono Lake excursion (ca 30–34 ka), whilst OSL measurements suggest that material incorporated into the basal sediments might date to 93 ± 9 ka. Four stratigraphic zones (A–D) were identified in the sedimentological data. The chronological model suggests that zones A–C were deposited between Marine Isotope Stages 5–2 and zone A during Stage 1, the Holocene. The palaeolimnological record tracks changes in the subglacial depositional environment linked principally to changing glacier dynamics and mass transport and indirectly to climate change. The sediment composition in zones A–C consists of fine-grained sediments together with sands, gravels and small clasts. There is no evidence of overriding glaciers being in contact with the bed reworking the stratigraphy or removing this sediment. This suggests that the lake existed in a subglacial cavity beneath overriding LGM ice. In zone D there is a transition to finer grained sediments characteristic of lower energy delivery coupled with a minor increase in the organic content attributed either to increases in allochthonous organic material being delivered from the deglaciating catchment, a minor increase in within-lake production or to an analytical artefact associated with an increase in the clay fraction. Evidence of biological activity is sparse. Total organic carbon varies from 0.2 to 0.6%, and cannot be unequivocally linked to in situ biological activity as comparisons of δ13C and C/N values with local reference data suggest that much of it is derived from the incorporation of carbon in catchment soils and gravels and possibly old CO2 in meteoric ice. We use the data from this study to provide guidelines for the study of deep continental subglacial lakes including establishing sediment geochronologies, determining the extent to which subglacial sediments might provide a record of glaciological and environmental change and a brief review of methods to use in the search for life.last_img read more

76ers top Jazz 103-94; move to 10-0 at home

first_img Tags: NBA/Philadelphia 76ers/Utah Jazz Associated Press FacebookTwitterLinkedInEmailPHILADELPHIA (AP) — James Ennis III hit a 3 and dropped for three pushups, and Tobias Harris scored 26 points to lead the Philadelphia 76ers to a 103-94 win over the Utah Jazz on Monday night.Al Horford scored 17 points to help the Sixers win for the eighth time in nine games and improve to 10-0 at home. A night after the Raptors led the Jazz by 40 points at halftime, the Sixers led by a more modest 18 points at the break — a cushion needed late to secure the win against Utah.Ennis, Philly’s super sub, had the crowd going wild in the first half when he was fouled on a 3 and did three quick pushups to stretch the lead to 26 points. Ennis missed the free throw but it hardly mattered at home. The Sixers flexed their offensive muscle and have started to play more like a team expected to contend for an Eastern Conference title than one that slogged through a 2-5 stretch in mid-November.Horford did his part, scoring five baskets in the first quarter for 12 points, to go with one ridiculous block. Bojan Bogdanovic took a turnover the other way and went straight down the middle for a layup attempt, when a hustling Horford caught up from the right and twisted his body for the rejection.They blocked, they exercised, they alley-ooped.Matisse Thybulle turned a steal into an alley-oop dunk for Ben Simmons and Harris came right back for a 3 that made it 52-27.Rudy Gobert led the Jazz with 27 points.The glaring blemish for the 76ers was another off-night for All-Star center Joel Embiid. Four games after Embiid went scoreless (0 for 11) against Toronto, he scored 16 points on just 5-of-13 shooting. Embiid played 29 minutes and continued to defy the load management expectations that had been set in recent seasons for the oft-injured big man. He looked gassed at the end of the fourth, right when the Jazz made a push to close within 10 with 4 minutes left. Joel Engles made it 99-92 on a 3-pointer with 57 seconds left to make it a bit uneasy for the Sixers before it dragged to its inevitable conclusion.TIP-INSJazz: G Mike Conley left in the second half with a tight left hamstring.76ers: G Joel Richardson sat out due to right hamstring tightness, and G Trey Burke missed the game with an upper respiratory infection.UP NEXTJazz: The Jazz return home to host the Lakers on Wednesday night.76ers: Play Thursday at Washington.

The Abu Dhabi National Oil Company (ADNOC) signed, today, two comprehensive framework agreements, with Abu Dhabi Ports and Aldar Properties PSJC (Aldar), to explore opportunities for collaboration in relation to ADNOC’s In-Country Value (ICV) Program.The agreements potentially extend the reach of ADNOC’s ICV Program to the logistics and construction sectors and reinforce ADNOC’s commitment to supporting the growth and diversification of the UAE’s economy.Under the terms of the agreements, ADNOC and both companies will explore potential opportunities for collaboration in creating additional skilled employment opportunities for UAE nationals in the private sector and sourcing goods and services within the UAE. In addition, the agreements would see ADNOC and both companies explore the potential for ADNOC to provide training on the implementation and measurement of compliance with the key objectives of its ICV Program.The agreements were signed by Rashed Saud Al Shamsi, Director, Business & Commercial Support Directorate at ADNOC; Captain Mohamed Juma Al Shamisi, Group CEO of Abu Dhabi Ports; and Talal Al Dhiyebi, CEO of Aldar.Al Shamsi said: “We are pleased to be partnering with these two companies, which share our vision to create, unlock and maximize value for the benefit of the UAE. ADNOC is, and will continue to be, an integral part of the UAE’s economy, and our In-Country Value Program is a central enabler of our commitment to drive progress and development in the nation as we deliver our 2030 strategy.“The program has been a huge success since we launched it almost two years ago and these framework agreements provide a solid foundation to strengthen and extend its reach. It is our firm hope that we can swiftly develop these two agreements into new partnerships that will create long-term and sustainable value for the nation, in line with the leadership’s wise directives.”Captain Al Shamisi said: “As a key enabler of trade and business across the country and the region, Abu Dhabi Ports is fully dedicated to promoting the socio-economic development and growth of the UAE. Today’s framework agreement with ADNOC through its successful ICV Program is a significant milestone in our mutual commitment to providing fuller and richer Emirati employment across all Abu Dhabi Ports’ assets – from Zayed and Khalifa Ports to KIZAD’s industrial zones.The success of the transport and logistics industry of tomorrow is dependent on the investment in the excellence of Abu Dhabi’s infrastructure and the expertise of our Emirati professionals, and with today’s agreements, we continue to make significant steps in that direction.”Al Dhiyebi said: “Embedded across Aldar’s corporate strategy is a commitment to sustainability, ensuring that its values extend through every link in the supply chain. We are committed to the UAE’s economic growth and diversification, and sustained investment within Abu Dhabi. This framework agreement with ADNOC provides us with access to an ICV Program that is already accepted by the market, and we look forward to its implementation at Aldar. We also look forward to working closely with all of our partners across our entire supply chain to drive more local content, support Emiratization and talent development, and collaborate on environmental initiatives to control climate change.”ADNOC’s ICV Program was launched in January 2018 to encourage private-sector partnerships and opportunities resulting from the company’s 2030 smart growth strategy, catalyze socio-economic development, improve knowledge-transfer and generate jobs for UAE nationals.More than 3,000 suppliers are certified in ADNOC’s ICV Program, which serves as the primary enabler of ADNOC’s – and suppliers’ – contributions to the UAE’s socio-economic growth and development. In the ICV Program’s first two years, ADNOC enabled the private sector to hire more than 1,500 Emiratis and drive more than AED 44 billion back into the UAE economy.

USNS Grapple heads for African deployment

first_img View post tag: US Navy Authorities USNS Grapple heads for African deployment Share this article USNS Grapple, U.S. Navy’s Military Sealift Command ship, departed Joint Expeditionary Base Little Creek-Fort Story in Virginia Beach on February 29 to begin its deployment to Africa in the 6th Fleet’s area of operations.With a crew of approximately 45 U.S. Navy divers and Civil Service mariners, Grapple is primarily going to provide dive salvage services in support of emergent situations such as requests to salvage and recover ships and aircraft, clear harbors and tow vessels.Chief Navy Diver Daniel Laube, master diver for Mobile Diving and Salvage Unit 2 (MDSU 2), said: “Our primary mission will be to work with our Africa partners. We will be training with them on how to further their diving programs. It is not going to be an easy deployment, but I am confident everything will get done.”The MDSU Navy divers deployed aboard Grapple perform a variety of missions to include underwater construction and demolition projects, search and rescue missions, and provide support for military and civilian law enforcement agencies.Grapple is specially designed to support diving and salvage operations at sea.Captain Curtis Smith, Grapple’s master, said: “Should there be an aircraft or a vessel which sinks, we arrive on scene to rescue the pilots and crew. We also are capable of recovering pieces of debris from the both the oceans’ surface and sub-surface of the sea.”“We are planning on spending time in Morocco, Algeria, the Ivory Coast and many additional African ports working to enhance and improve the practices of our African partners”, Captain Smith added.It will take approximately two weeks for Grapple to travel to Africa. Grapple is expected to complete its current deployment in late summer.center_img View post tag: USNS Grapple Back to overview,Home naval-today USNS Grapple heads for African deployment March 2, 2016last_img read more

Donations boom for Oxbridge

first_imgDue to government cuts to tertiary education, UK universities are increasingly being left to source their own funding – with Oxford and Cambridge leading the way, according to the findings of a recent report by the international credit rating agency Moody’s. The report, which looks at data from the last six academic years, also suggests that universities are increasingly  following the funding model of American universities. Although the £13.8 billion in charitable donations received by top US universities still dwarfs the record £774 million that UK institutions received, the rate of growth of private donations was far higher in the UK. It was further suggested in the report that the growth in both the number and size of donations comes out of necessity.However, the highest ranked universities received far more funding than their academic rivals, with Oxford and Cambridge collectively receiving almost half of all charitable donations made over the last six years.The statisticians found that “in both the US and the UK, philanthropic support is concentrated among the market leading, elite and highly rated universities, showing that brand recognition and a strong market presence are keys to successful fundraising in higher education.”last_img read more

2009 flu could have echoed 1918

first_imgThe 2009 H1N1 pandemic had the potential to be as deadly as the 1918 Spanish flu outbreak, which killed more than 50 million people, Canada’s chief public health officer said Monday, crediting modern medical science and public health practices for the far-lower mortality.David Butler-Jones said were it not for the development of new antiviral drugs, medical equipment like ventilators, and other advances, global deaths would have far outstripped the estimated 12,000 to 18,000 from H1N1. Butler-Jones said the H1N1 outbreak was a lot like the Y2K computer bug, where the fear that massive computer failures would result from two-digit computer clocks resetting to 1900 instead of 2000 prompted a major effort to update equipment ahead of Jan. 1, 2000. Afterward, when there was little disruption, some critics complained that the effort had never been needed in the first place.“People forgot that computers that weren’t treated did fail,” Butler-Jones said. “If the approach to public health [during H1N1] had been like it was in 1918, it would have been 1918 all over again … It was not a trivial event.”Butler-Jones discussed a variety of public health issues, from flu pandemics to the spread of obesity to U.S. health care reform, during a visit to the Center for Government and International Studies’ Knafel Building. Butler-Jones delivered a talk called “Living Forward, Understanding Backward: Transforming Public Health in the 21st Century.” The event was sponsored by the Weatherhead Center for International Affairs and the Center for Population and Development Studies.Butler-Jones said the world is lucky the H1N1 pandemic started in North America, where early action muted the spread of the worst strains. He also said that, although the pandemic is thought to have started in Mexico, within two days it was found coast to coast in Canada, meaning it probably had been there already. Butler-Jones said he is concerned about a more novel strain emerging, like the H5 or H7 avian flu viruses. He said that nature is the world’s “best bioterrorist,” with flu viruses potentially more easily spread and more lethal than any human anthrax attack.“The lessons from the pandemic will put us in a better position,” Butler-Jones said.The obesity epidemic is another major health concern, he said, with its companion rise in diabetes already affecting parts of the world, such as the Pacific Islands, where 30 percent of the population is diabetic. Butler-Jones questioned the effectiveness of approaches such as raising taxes on unhealthy foods, and said that, instead, the government should subsidize healthy foods, which should be placed prominently close to cash registers, with junk food in the back.“It’s not about getting rid of bad choices, but making good choices cheaper and easier,” Butler-Jones said. “There’s actually a fair bit of evidence that if people have a choice and it’s an equal choice, they will do the right thing.”Other modern challenges include how to communicate effectively with the public at a time when the channels to do so are fractured into many different streams, split among social media, the Internet, and traditional outlets.Public health has also become much more political, he said, a situation that has both advantages and disadvantages. While added prominence brings more attention to public health messages and greater funding, it also brings more expectations and scrutiny.With respect to obesity, Butler-Jones said, that means more attention from other government ministries to youth sports and recreation, as well as to how schoolchildren spend their after-school hours.As for health care reform in the United States, Butler-Jones said the size of the vested interests involved and the polarization of the opposing sides in the dispute will make it a difficult fight. The biggest challenge will be to create coalitions, which are only built on mutual respect, even among those who disagree.last_img read more
