Atmospheric decadal variability from high-resolution Dome C ice core records of aerosol constituents beyond the Last Interglacial

first_imgAlong the EPICA Dome C ice core, we measured concentrations of different water-soluble aerosol constituents and deduced total depositional flux records. Here we present high-resolution sodium, calcium, ammonium and nitrate data covering the last 173,000 years. The first three of these species are passive tracers and reveal source and long-range transport changes whereas nitrate is deposited reversibly. However, it can be used to check isotope-derived accumulation rate estimates, a prerequisite to calculate total depositional fluxes. During the last two transitions from glacial to interglacial periods, changes in the total depositional flux differ strongly for different aerosol species. The largest changes are observed in the terrestrial aerosol proxy non-sea salt calcium, only moderate changes occur in the marine sea salt indicator sodium, while ammonium, a proxy for marine bioproductivity, remains rather constant. In agreement with previous studies, we find that only considerable glacial–interglacial changes at both, the terrestrial and the marine sea salt aerosol source can explain the observed pronounced changes. The unprecedented high-resolution of our data allows for the first time the examination of decadal variability back to the penultimate glacial period. On the one hand, we find occasional fast shifts occurring within a few years; here we present such an event in the calcium record from the penultimate glacial period. On the other hand, we examine variation coefficients and pairwise correlation coefficients, both determined in 200-year windows. They generally reveal only moderate changes. During glacial periods, slightly lower variation coefficients are found, concurrent with slightly higher correlation coefficients, which points to a more uniform and stronger coupled atmospheric long-range transport of the different aerosol species to the East Antarctic Plateau and less influence of cyclonic activities during cold periods. The opposite is observed for interglacial periods with probably even reinforced importance of cyclonic influences during the Last Interglacial period, the Marine Isotope Stage 5.5. This period reveals no evidence for abrupt climatic changes in any of the species, however, the marine sea salt aerosol indicator sodium shows a distinct minimum followed by a pronounced increase. This pattern is explained by significantly reduced sea ice production in the Indian Southern Ocean sector, which is believed to be the dominant source of sodium deposited in Dome C during warm periods.last_img read more

Press release: Welsh Secretary chairs panel on government powers post Brexit

first_imgSecretary of State for Wales Alun Cairns will today (Thursday 19th April) chair a panel of experts from business, manufacturing, farming, and the voluntary sector to examine how former EU powers should be used to help Wales thrive in a post-Brexit world.The meeting is one of an ongoing series to ensure that the views of Welsh business and industry on Brexit are heard at the heart of UK Government. The 90-minute session will examine issues including how powers returning from the EU should be exercised in future; how such frameworks could best operate in practice and how powers could be exercised at a devolved level.Secretary of State for Wales Alun Cairns said: The economy is continuing to grow – this week’s employment figures illustrate that fact – and we are continuing to attract investment because of our strong infrastructure and skilled workforce. But to keep on doing that we need to provide certainty and clarity about how post-Brexit powers are best deployed. I want to hear straight from the people who drive the Welsh economy and today’s panel will provide valuable insight into how we can position Wales to prosper after the UK leaves the European Union. Delegates invited to the meeting come from organisations including the Chamber of Commerce; the Institute of Directors; the Federation of Small Businesses; NFU Cymru; CBI Wales; the Country Landowners Association; Admiral Group and Airbus.ENDSlast_img read more

News story: Northern transport investment to help create thousands of jobs

first_img Roads media enquiries The middle (east of England plus East Midlands plus West Midlands) 864 The north(north-east plus north-west plus Yorkshire and Humber) 831 Media enquiries 020 7944 3021 Spend per head by region 2018/19 to 2020/21 – total 3 years Transport spending in the north over the next 3 years will be higher than in London and the south, new figures today reveal (25 June 2018).The Department for Transport’s analysis of future spending shows, between 2018 and 2021, it will be investing £831 per head on road and rail upgrades in the north-east, north-west and Yorkshire and the Humber – more than £30 more per head than London and the south at £799.The figures emerged as Aviation Minister Baroness Sugg visited Liverpool Airport ahead of attending the Northern Transport Summit in Manchester, where she will say Heathrow expansion could lead to tens of thousands of jobs as businesses take advantage of the UK’s improved connections with the rest of the world.Aviation Minister Baroness Sugg said: The government last week confirmed that it is prepared to intervene to reserve slots at Heathrow for flights to airports in nations and regions around the UK if expansion goes ahead. It would ensure flights to domestic airports are safeguarded, ensuring important links will remain in place. This is in addition to Chris Grayling’s confirmation that 15% of the new capacity at Heathrow would be reserved for domestic flights.On rail, more than £1 billion is being spent on improving the north’s rail network with further investment through the Northern and TransPennine Express franchises to deliver room for 40,000 more passengers to travel on over 2,000 more services a week, with all trains replaced or refurbished by 2020. The government also plans to invest a further £3 billion upgrading the Transpennine rail route, better connecting Manchester, Leeds and York. Rail passengers will also benefit from smart ticketing, reducing the stress of buying tickets at a station.In addition, as part of the government’s commitment to Northern Powerhouse Rail (NPR), Transport for the North has been given £60 million to develop proposals for the scheme, alongside investing £300 million to ensure HS2 can accommodate future NPR services.On roads, last month, the last stretch of motorway-standard road between Newcastle and London via the A1(M) and M1 was officially opened, providing quicker connections from the north-east, creating new opportunities for businesses. The final section of the M62 upgrade between Leeds and Manchester is expected to start construction in 2019/20, leading to quicker, safer and more reliable journeys.Highways England will also start constructing a further 22 projects in the north over the next 3 years, including 3 upgrades on the M6 near Manchester, the A585 Windy Harbour to Skippool, dualling the A1 between Morpeth and Ellingham and improving junctions on the M621.Other improvementsOther improvements to benefit the north include:center_img Out of hours media enquiries 020 7944 4292 Switchboard 0300 330 3000 The south (London plus south-east plus south-west) 799 innovative trials in York and Newcastle will see how wireless technology can help reduce congestion in cities with vehicles communicating with traffic lights in the long term, HS2 will enable quicker journeys around the north, as well as open up space on the existing rail line for commuter services Sheffield’s ground-breaking new tram-train project – Supertram – is now in service on the existing tram network and from later this year it will use the rail network to give passengers quick and easy travel between Sheffield and Rotherham, cutting congestion and improving connectivity we are supporting the Tyne and Wear Metro, which connects Newcastle, Gateshead and Sunderland with Newcastle Airport, with £317 million for its reinvigoration and renewal programme, £229 million towards its running costs and, in the Budget, the Chancellor announced a £337 million direct grant to deliver a new fleet of trains for the Tyne and Wear Metro the A6 Manchester Airport Relief Road will also mean it will be easier for passengers to get to and from flights. This is one of 6 major local road schemes due to complete in the next three years. Stockport Town Centre Major Scheme, East Riding Road Maintenance and North Yorkshire Road Maintenance Scheme are under construction. Congleton Link Road and Sunderland Strategic Transport Corridor could also be completed if business cases are approved. A further 5 schemes are also expected to start by 2021 – Preston Western Distributor Road, Poynton Relief Road, A630 Parkway, Middlewich Eastern Bypass and Jock’s Lodge Junction We are investing more than £13 billion to improve connections across the north between 2015 and 2020, getting people to their work, family and friends, quicker and easier than before. This investment demonstrates the government’s commitment to the Northern Powerhouse, which will help unlock economic growth and much-needed housing across the region. And a new Heathrow runway will bring further benefits to the north, better connecting the region’s airports with the UK’s hub airport and opening up new trade opportunities which could deliver a further boost to the northern economy.last_img read more

Hungry warriors

first_imgBy Brad HaireUniversity of GeorgiaThey are covert operatives with code names like big-eye, lace wing, lady beetle and pirate. They’re not military, but they are hungry. And they secretly fly, crawl and hop through farmers’ fields, eating insects and worms that eat their crops.Beneficial insects don’t get the credit they deserve for providing cheap, environmentally safe control of crop-damaging insects, said John Ruberson, an entomologist with the University of Georgia College of Agricultural and Environmental Sciences.”You will rarely see (beneficial insects) doing their thing,” said Ruberson, who mainly conducts research on cotton insects. “After they’re through, they tend to disappear quietly back into the field.”Who’s hungry?That cotton field you drive by during the summer may seem quiet and peaceful. But it’s not. It’s a battle field between the hungry and the hungrier.Worms, like the cotton bollworm, tobacco budworm and beet armyworm, are major enemies of cotton farmers. These worms are eating machines, and they love to feast on the cotton plant. And the damage they do can seriously reduce yields.However, just as the worms love to eat the cotton leaves, the “good bugs” love to eat the worms. In some cases, if left unfettered, these beneficials can help farmers knock out the worms without the use of insecticides, Ruberson said.”You may get a lot of pest eggs, but the caterpillars that hatch from them may not reach a treatable level because things are eating them,” he said. “We’ve seen untreated cotton do perfectly well throughout the season without much yield damage.”Better controlIn the past decade, genetically engineered cotton has been used to control worms in cotton through a virus only toxic to the worms. Last year, about 55 percent of Georgia’s cotton was genetically engineered. This has reduced the amount of insecticides needed for cotton pest control in this type of cotton and allowed more beneficial species to survive.Traditionally, though, U.S. farmers must spray insecticides to control worms in their fields when they do get out of hand. It can vary from year to year, but Georgia farmers spend around $30 million each year to control pests in their fields.Good with the badBut insecticides aren’t very selective. They kill the harmful insects, but they also wipe out the covert, beneficial bugs, he said. That’s a shame.Cotton worms usually invade fields for the first time each year around June. Some cotton farmers tend to reach for the insecticides around this time to protect against the invasion.But farmers should hold back, Ruberson said, on that first, blanket insecticide spray.Cotton plants can usually recover from worm damage that early in the season, he said. But it’s hard for the beneficial insect populations to recover from it.As many as 90 percent of most beneficial insects die in winter. They need the spring and early summer to increase their numbers. If they have that chance, a farmer could see the benefits later in the year.Ruberson said new, more selective insecticide tools are coming into the marketplace. These tools, along with better management practices and understanding of how insects act, will help sustain Georgia’s cotton industry while making it more friendly to the environment.”Really, the overall goal of this type of research is to make our (Georgia) cotton an economically viable crop to grow,” he said.Beneficial insects can help do this by doing what they do naturally, he said, without the farmer doing anything.last_img read more

Chilean Marine Corps to Receive Colt M4 Rifles from U.S.

first_img The final shortlist from the CIM’s selection process also included the HK416 made by German manufacturer Heckler & Koch, and the Belgian SCAR-L produced by FN Herstal. By Dialogo April 03, 2013 The M4 version made by U.S. manufacturer DPMS Panther Arms was also evaluated, but it was rejected due to flaws that occurred when used by the Army’s Special Forces Brigade. The first order is intended to equip the combat units of the Amphibious Expeditionary Brigade (BAE); a 1,400-member seaborne rapid deployment structure created in 2012, and the deliveries are expected to be completed in 2014. The rest of the BAE members and the other CIM units will continue to use the 5.56-mm HK33A2 rifles, acquired in the early 90s. While the CIM favored the rifles’ durability under extensive and prolonged use in inhospitable environments, as well as the chance to incorporate a variety of weapon accessories, the Army gave prominence to the prospect of assembling rifles in Chile, with the ability to integrate a percentage of locally manufactured parts and components. center_img The decision to acquire the M4 rifles was made after a lengthy assessment and negotiation process, initially conducted jointly with the Chilean Army, which was also looking for a new assault weapon for its infantry units. The Chilean Marine Corps (CIM) made its first request to obtain 2,000 of the 5.56-mm M4 assault rifles from U.S. manufacturer Colt on March 29 in Santiago, Chile, under a contract for an undisclosed amount that includes an option for a second request of similar volume to be finalized shortly.
