Proxies and measurement techniques for mineral dust in Antarctic ice cores

first_imgTo improve quantitative interpretation of ice core aeolian dust records, a systematic methodological comparison was made. This involved methods for water-insoluble particle counting (Coulter counter and laser-sensing particle detector), soluble ion analysis (ion chromatography and continuous flow analysis), elemental analysis (inductively coupled plasma mass spectroscopy at pH 1 and after full acid digestion), and water insoluble elemental analysis (proton induced X-ray emission). Antarctic ice core samples covering the last deglaciation from the EPICA Dome C (EDC) and the EPICA Dronning Maud Land (EDML) cores were used. All methods correlate very well among each other, but the ratios of glacial age to Holocene concentrations, which are typically a factor similar to 100, differ between the methods by up to a factor of 2 with insoluble particles showing the largest variability. The recovery of ICP-MS measurements depends on the digestion method and is different for different elements and during different climatic periods. EDC and EDML samples have similar dust composition, which suggests a common dust source or a common mixture of sources for the two sites. The analyzed samples further reveal a change of dust composition during the last deglaciation.last_img read more

Who is Bernard Looney? Profiling the new CEO of BP with a ‘modern’ leadership outlook

first_imgAhead of the Irishman’s first day as the new boss of BP, Greenpeace activists held a solar panel protest outside the oil and gas firm’s London HQ “I encourage you all to be candid – I consider honest and open discussion crucial. It’s what I care about and what I hope I can promote here.”Looney also spoke of being passionate about mental health and inclusivity as he aimed to present a modern leadership style in line with the 21st century outlook BP has attempted to convey.According to the company, the top-performing regional team of the upstream business he ran was one-third women, with a third coming from outside the UK and US, while he has talked openly about mental health issues on BP’s internal social media platform.Lightsource BP CEO Nick Boyle has spoken about how Looney “instils a confidence and a positive, can-do mentality that is infectious”“BP is a big company, but he’s always been well known as a charismatic, lead-from-the-front, roll-your-sleeves-up type of guy,” he added. “The big plus with Bernard is that he gets it.”This final point is something both those inside and outside BP will hope is true of Bernard Looney. Since 2002, Looney has risen up the leadership ranks in a variety of roles. After a stint as BP Alaska’s senior vice-president, in 2006 he was appointed head of the group chief executive’s office, where he worked directly for CEOs John Browne and Tony Hayward.While managing director of BP North Sea, he was redeployed to the Gulf of Mexico to help stop the millions of barrels of crude oil that were spilling into the sea following the 2010 Deepwater Horizon rig explosion.The disaster is considered to be the largest marine oil spill in the petroleum industry’s history, killing 11 people, injuring 17 others and resulting in a record $18.7bn US government fine for BP – which had spent more than $65bn on the entire clean-up by 2018.It was also the most challenging time of Looney’s careers, he has since revealed, but BP has credited him with leading the creation of “central drilling and projects functions” following the accident.Another key position was chief operating officer of production, before his biggest appointment as chief executive of the upstream business in 2016.Bernard is a fellow of both the Royal Academy of Engineering and the Energy Institute, while he is a mentor in the FTSE 100 Cross Company Mentoring Executive Programme. BP CEO Bernard Looney (Credit: BP) After almost three decades working at BP, Bernard Looney has taken on the top job as CEO of the Big Oil company.The 49-year-old Irishman, who previously ran the UK firm’s upstream business, succeeds Bob Dudley in the role he started today (5 February).It wasn’t the easiest of starts as he faced protests from environmental activists outside its London headquarters and will be charged with navigating the world’s fifth largest oil company by revenue through a global transition towards cleaner energy sources.NS Energy takes a closer look at the man in the hotseat – who has even set up his own Instagram account as he attempts to modernise BP. Who is Bernard Looney? From a family farm in Ireland to BP execBorn in County Kerry and raised on a dairy farm as one of five children, Looney was the first person in his family to go to university.He studied electrical engineering at University College Dublin, later earning a master’s degree in management from Stanford University’s Graduate School of Business.In 1991, he joined BP as a drilling engineer and worked in operational roles in the North Sea, Vietnam and Gulf of Mexico – where he worked on the discovery of Thunder Horse, a major offshore oil field about 150 miles (240km) south-east of New Orleans.center_img Bernard Looney’s upstream successes and group CEO appointmentAs the upstream CEO, Looney was responsible for all BP’s oil and gas exploration, development and production activities worldwide.The company says its process and personal safety performance improved by 35% and 20% respectively during his tenure, while production grew by 20% as he drove the launch of 23 major projects “ahead of schedule and under budget”.He is also credited with leading access into new countries, including Senegal and Mauritius, while creating new business models such as Aker BP in Norway and leading the oil and gas industry on new methane detection methods.Looney was behind BP’s biggest deal in 20 years when the company bought miner BHP’s US shale assets for $10.5bn in 2018, while he drove last year’s proposed sale of the high-emitting Alaskan business where he once held a senior position.It was this work – and perceptions from the top he has been a leader in the making for years – that led to him being appointed as a replacement for New York-born Dudley, who had been in the role since October 2010.Bob Dudley stepped down as BP CEO after almost 10 years in February 2020 (Credit: BP)Dudley said his successor “knows BP and our industry as anyone, but is creative and not bound by traditional ways of working”.“I have no doubt that he will thoughtfully lead BP through the transition to a low carbon future,” he added.Looney, who now oversees 73,000 staff across 78 countries, said he was “humbled by the responsibility” and excited about the company’s future.He added: “Our company has amazing people, tremendous assets, and a set of core values that guide our actions, but, most of all, we have a desire to be better.“I look forward to tapping into that desire and building on the strong foundation that Bob has built as we meet society’s demand for cleaner, better energy.” Challenges facing Bernard Looney at BP – and how he will tackle climate changeDespite trying to paint itself as a modern energy company, BP has come under fire for being too slow to tackle climate change.Recent investments have included buying UK electric vehicle charging point operator Chargemaster for $160m and spending $200m on a 43% stake in Lightsource, which has since been rebranded as Lightsource BP and is Europe’s largest solar power project developer.BP has 18,000 forecourts across the world (Credit: Flickr/Mike Mozart)But the company only committed about $500m to investment in low-carbon technologies for 2019, representing a drop in the bucket for a business that raked in a $303.7bn turnover and $9.4bn profit the previous year.This also reflects about 4% of the total capital expenditure of $15bn to $17bn.It has led to legal challenges by environmental campaigners that BP is “greenwashing” its customers by making claims it is focused on climate change and low-carbon energy in an advertising campaign.The Royal Shakespeare Company recently dropped BP as a sponsor, while Greenpeace protesters climbed a North Sea oil rig to force a 12-day stand-off in June last year.Greenpeace was again at the centre of the latest protest, with about 100 activists placing 500 solar panels outside BP’s central London headquarters in the early hours of Wednesday morning to mark Looney’s first day as chief executive.All this means that climate change appears to be the big issue occupying the new boss’ in-tray.Greenpeace climbers on a BP oil rig in Cromarty Firth, Scotland (Greenpeace)Analysts have speculated how he will approach the emissions generated by customers – mainly people filling up their cars with petrol and diesel at BP’s 18,000 global forecourts – rather than just its own and the supply chain.The company is responsible for 491 million tonnes of carbon emissions each year, with customers accounting for 437 million tonnes of that total.In Looney’s favour is a track record of sorts in this field. He is said to have been the driving force in improving sustainability within BP’s upstream business, reducing CO2 emissions by almost three million tonnes in the past two years.He has also spoken about BP’s “skill and will to drive the real system change that the world needs and wants to see”, and is keen for the company to demonstrate how it will play its part in meeting the goals of the 2015 Paris Agreement to limit the global temperature rise to “ideally” 1.5C above pre-industrial levels.Industry observers say it will be interesting to follow the near-term goals he sets, as well as long-term objectives like a potential 2050 carbon-neutral plan in line with the UN’s target, but he will also have to please shareholders – who Dudley has previously claimed don’t want to fund renewables via a dividend cut. Bernard Looney: The Instagrammer CEO is a modern leaderPerhaps one of the most notable moves from Looney already was his decision to set up a personal Instagram account a week before his promotion.By Wednesday afternoon, he had amassed almost 3,000 followers and posted five images, including the first photograph in which he displayed a casual look with jeans and a jumper.In the post, he wrote: “I know a lot of people have views on oil and gas companies and our role in the energy transition.“I would like to use this platform to talk openly about that and explain the role BP can play, as I believe we share the same concerns and hopes.“I want to use Instagram not just as a platform to talk but also to listen and understand your thoughts, concerns and interests.last_img read more

Press release: Illegal fishing clampdown throughout East Midlands

first_imgPeople are urged to report illegal fishing to the Environment Agency’s incident hotline on 0800 80 70 60, or Crimestoppers anonymously on 0800 555 111. Environment Agency enforcement officers in Nottinghamshire will be patrolling waters throughout the East Midlands this bank holiday weekend (26 to 28 May 2018) as part of a clampdown on illegal fishing.The officers will be making sure anyone fishing is obeying the law. They’ll be checking that people are not fishing in waters closed to anglers, are using the right tackle and equipment, and have a valid fishing licence.Fish legally this bank holidayBank holiday weekends are a great opportunity for families to get out and do some fishing on waterways and the Environment Agency is keen to ensure everyone is enjoying themselves and doing the right thing.In April this year, enforcement officers checked 1,074 anglers, with the majority being fully licensed and compliant. In that period, officers reported 31 people for offences. During the last May bank holiday weekend, 530 anglers were checked and 30 people were reported for offences.Callum Underhill, fisheries enforcement officer at the Environment Agency, said: We will once again be out and about around the county this bank holiday to make sure everyone is fishing legally. Anyone caught breaking the law can expect to face prosecution. We regularly carry out enforcement operations in order to protect fish stocks and improve fisheries. We take all kinds of illegal fishing extremely seriously, whether it’s fishing without a licence, using illegal equipment or fishing in the close season. Illegal fishing is not just unfair on other anglers who fish within the law, it also endangers the future of the sport by damaging the sustainability of fish stocks, so it is important for people to report to us any information about suspected illegal fishing so we can investigate.center_img Officers to target hotspotsThe Environment Agency’s work is intelligence-led and officers work closely with partners to target known hotspots and act on reports of illegal fishing.Anglers are reminded that it is currently the close season for coarse fishing, so fishing for coarse fish on rivers and streams is not permitted. This is to protect breeding fish, helping to safeguard stocks for the future. Anglers are encouraged to check which waterways are open to fishing by reading their area’s byelaws.Investing in fishMoney from fishing licence sales is invested in England’s fisheries, and is used to fund a wide range of projects to improve facilities for anglers, including protecting stocks, restoring fish stocks through re-stocking, eradicating invasive species, and making fish habitat improvements. Fishing licence money is also used to fund the Angling Trust to provide information about fishing and to encourage participation in the sport.Anyone who wants to go fishing needs to buy a fishing licence. A full annual licence costs from just £30 and is available online.last_img read more

Howard Hall hosts annual Totter for Water

first_imgNew students on campus might wonder why there will be a teeter totter in the middle of South Quad on Thursday and Friday. Each fall, the women of Howard Hall spend 24 hours riding the totter to help raise money for projects dedicated to clean water access in communities across the globe as part of the dorm’s annual Totter for Water event.At 6 p.m. Thursday, Howard’s residents will begin taking shifts operating the totter and continue their work throughout the night. Students will have the opportunity to ride the totter if they desire and are encouraged to help Howard in their fundraising goals. This year, sophomores Eileen Leach and Sarah Walters are planning the event.Leach and Walters said the dorm is hoping to raise $25,000 at this year’s event — about $7,000 more than last year. To accomplish such a task, they began the planning process before they arrived to campus.“Sarah and I have been working on the project for several weeks now, we contacted the organization, made t-shirt designs and poster designs,” Leach said.Students working on the event attempt to involve all members of the Notre Dame community. The money Howard fundraises comes from student donations on the day of the event, from both online donations and from selling succulents on South Quad. Anyone interested in donating can give to the cause on the Student Shop ND website. There will also be other forms of entertainment on Thursday night, Leach said.“This year we are having a bouncy house on Thursday as well,” she said.Leach explained that all of the money Howard raises from the event this year will benefit a community in Ecuador.“In the past the money has gone to build wells or develop water systems for schools,” she said. “We have worked with Engineers without Borders in the past and that’s also who we’re working with this year — the Notre Dame chapter. They are going to be traveling to San Pedro de Suma, Ecuador, to build a water chlorination system, specifically for a school in the region.”Sophomore Catherine Connell said she participated last year after noticing the presence of a seesaw on the quad.“I saw a teeter totter on South Quad, so some friends and I went to see what was going on,” she said. “We ended up riding the totter and buying succulents. It was a fun opportunity to break from studying and also help a good cause.”Alix Basden, a Howard sophomore who said she will be riding the totter at midnight, said the event helps the dorm grow in community.“Howard is the single most intentional community I have ever been a part of,” she said. “It is a strong sisterhood. [With Totter], we create an international community and partnership.”For instance, last year Basden shared her totter shift with someone she didn’t know particularly well at the time. Now, that situation has changed.“It’s pure fun to be out on that seesaw,” Basden said. “Last year, I did the 1 a.m. shift. I went to the Totter with a girl I wasn’t that close with at the time, and we rode the Totter for 30 minutes together. Now she’s my roommate.”Tags: Community, ecuador, Howard Hall, totter for waterlast_img read more

Corn planting

first_imgBy Brad HaireUniversity of GeorgiaFor Georgia farmers who are planting corn now to start the 2006 growing season, the good news is that corn prices are higher now. Unfortunately, it will cost more to grow it. But University of Georgia specialists say growers can do some things to make the most of their efforts.Corn prices in Georgia averaged $2.15 per bushel last year, the lowest in five years. The price now for the 2006 crop is around $2.70, said Nathan Smith, a UGA Cooperative Extension economist. A bushel of corn weighs about 56 pounds.Smith tells farmers to think about contracting some of their 2006 crop now. “Prices now are attractive,” he said, “based on what we may see later in the season.”Getting the best price will be critical because fuel and fertilizer costs are up this year, too, he said. Georgia farmers spent about $400 per acre to grow irrigated corn last year. It’ll cost about $458 this year.Among corn-producing states, Georgia is a minor player. The state’s farmers harvested about 230,000 acres of corn last year and averaged 130 bushels per acre.A little spaceUGA Extension agronomist Dewey Lee said farmers may want to think “spacing” to get more out of their corn.They typically plant corn that will grow under irrigation at 28,000 to 30,000 seeds per acre in rows 3 feet apart. On land without irrigation, they plant 18,000 to 20,000 seeds per acre.Research has shown, Lee said, that farmers can improve yields by simply planting the same number of seeds in rows 20 inches apart.This allows for a fuller plant canopy, blocks out weeds and cools down the soil. It can all add up to as much as 15 percent higher yields in Georgia, he said. The practice has been used in the Midwest, where most of the U.S. corn crop is grown.Most Georgia corn farmers plant peanuts and cotton, too. Most of their planters are set for all crops, Lee said, and not for 20-inch rows. But it’s something farmers could consider.Fertility research helps farmers decide how much fertilizer they need to use to get the yields they want. Lee tells farmers to use 1.2 pounds of nitrogen per acre for every bushel of corn they want to grow. For example, if a farmer wants to make 200 bushels per acre, he needs to apply 240 pounds of nitrogen.Corn needs a lot of water, either from irrigation or rainfall. It needs about one-third of an inch a day during its silking stage, which happens in Georgia in late May and early June. About 65 percent of corn in Georgia is irrigated.Fighting diseaseDiseases cost Georgia corn farmers about $10 million a year. But it’s rare for a corn disease to destroy an entire field in Georgia, said Bob Kemerait, a UGA Extension plant pathologist.Historically, the state’s farmers haven’t used fungicides to control diseases. It just wasn’t economical. A disease called southern corn rust, however, can cause severe yield losses in Georgia corn.Some new fungicides, though, can make a difference. Farmers who want to go for high yields should consider using them, the experts say, to get the most from their corn.Before using fungicides, however, they should think about the weather, the time of year and how much disease pressure is in a field. Sometimes farmers get a return on using them in Georgia. Sometimes they don’t. Research in the UGA College of Agricultural and Environmental Sciences during the past three years can help farmers make that decision.To find out more about corn, agriculture or other information from the CAES, contact your local UGA Extension office at 1-800-ASK-UGA1.last_img read more
