Rates and mechanisms of turbulent dissipation and mixing in the Southern Ocean: Results from the Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES)

first_imgThe spatial distribution of turbulent dissipation rates and internal wave field characteristics is analysed across two contrasting regimes of the Antarctic Circumpolar Current (ACC), using microstructure and finestructure data collected as part of the Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES). Mid-depth turbulent dissipation rates are found to increase from O (1×10-10 W kg-1) in the Southeast Pacific to O (1×10-9 W kg-1) in the Scotia Sea, typically reaching 3×10-9 W kg-1 within a kilometre of the seabed. Enhanced levels of turbulent mixing are associated with strong near-bottom flows, rough topography, and regions where the internal wave field is found to have enhanced energy, a less-inertial frequency content and a dominance of upward-propagating energy. These results strongly suggest that bottom-generated internal waves play a major role in determining the spatial distribution of turbulent dissipation in the ACC. The energy flux associated with the bottom internal wave generation process is calculated using wave radiation theory, and found to vary between 0.8 mWm-2 in the Southeast Pacific and 14 m W m-2 in the Scotia Sea. Typically, 10-30% of this energy is found to dissipate within 1 km of the seabed. Comparison between turbulent dissipation rates inferred from finestructure parameterizations and microstructure-derived estimates suggests a significant departure from wave-wave interaction physics in the near-field of wave generation sites.last_img read more

Come out on top

first_imgIf you read last week’s article, those glorious hats should now be adorning your rain-drenched hair. Do not think, however, that just because it is cold, and you have a big bright hat on, you can hide away from having a suitable top. Tops are one of the hardest things to get right. The colours, the shapes, the sizes – there is so much that can go wrong – and so little that ever goes completely right. Boys: It is important not to assume that every t-shirt that looks like your size is your size. Having found the appropriate chest size, look at the length. With your arms in the air, the t-shirt should just reach the top of your waistband (assuming you aren’t wearing your trousers half way down your bum, or around your rib cage). The colour really can be anything you like, but originality is key, so try your best. As it is chilly, a nice jumper always looks good. Preferably vnecked, and non-stripey. Stripes are everywhere, as Gap goes on sale. Shirts look good, but I am not a fan of the ‘I look smart casual, because I have a smart shirt but haven’t tucked it in’. I think there is definite evidence to show that tucked in shirts, pulled out (so it doesn’t look like a skin tight body warmer) look very good. With rolled up sleeves, they definitely suit those of you with boatie hats, or fedoras (I like to think I can advise the minority too). Girls: Watch out for the size. Your breasts, and for that matter your bra, are very important here. If you are going to wear a tight top, don’t wear a ruffled bra, and make sure your bra fits – no one wants to see back spillage. If you have big breasts DO NOT be overly summery, i.e., avoid too much ornamentation and busy patterns. Halter necks can look good, but if you have big breasts, do some damage limitation. If you are less well-endowed in the chest area, then you can get away with anything – I think loose tie halter necks look especially good. Colour, shape, design – paying more definitely means getting more. Even if two t-shirts look the same, always get the more expensive one – it will have subtle tailoring that makes the top look like it fits. Beware of the mass produced t-shirts – vintage style is only vintage if it isn’t worn by anybody else. I also offer a caveat about strapless bras. They have a tendency to pre-occupy the wearer, causing them to ‘hoist’ at every opportunity. Also, they tend to pull your breasts down, making them look saggy. Two essential accessories: double-sided sellotape – keep those boob tubes over your breasts. And duct tape: keep those breasts in check (I have not tested the duct tape advice – it seems intrusive and painful. I just stick to bras). And if you are going to wear spaghetti tops, white bras with black tops are not attractive. Be subtle – yes, the boys do look at your breasts, regardless of what you wear, or how you wear it.ARCHIVE: 2nd week TT 2004last_img read more

Woman claims to be at Oxford, scams parents for £250,000

first_imgA heroin addict has been convicted of conning her own parents out of £250,000 by telling them she was studying for a DPhil at Oxford.Nicola Boardman, now 34, has been lying to her parents Frank and Marilyn for four years about fictitious research and living expenses supposedly incurred while studying for a degree in Social Sciences at Oxford.Rather than putting it towards academic study, she spent the money on heroin, lavish holidays, and a £10,000 wedding ceremony in London to which her parents were not invited. She pled guilty to fraud on April 20 at the Truro Crown Court in Cornwall, and was sentenced to three years and four months in prison.In his statement to the court, her father Frank said, “I personally have been deprived of my retirement that I have worked hard for, for the last 40 years.”Indeed, the parents sold their home after their daughter promised that her expensive pretense of research would yield a three million pound payout when it was finished, an unusually high sum for academic work.Boardman went so far as to tell her parents that she’d had a stillborn child, when in fact she’d chosen to abort it, and held a fake ash-scattering for the baby. She eventually revealed to her parents that she had relapsed into her teenage heroin addiction, but continued to conceal part of her other uses for their money.This deception apparently began shortly after Boardman graduated from Camborne College, part of Plymouth University, with a first class degree in Social Sciences.After graduation she told her parents that she wanted to continue into graduate study, and convinced her father to drive her to both Oxford and Cambridge for interviews, though in fact she had applied to neither university.Boardman then told her parents that she had been accepted to both, but chose Oxford. This deceit lasted for over four years, during which Nicola Boardman forged email correspondence with academics and evidence of her research in what the judge described as a “prolonged” and “sophisticated” operation.Rose Atkinson, a Physicist at Keble told Cherwell , “I’m actually at Oxford and my parents won’t give me 250k!”Dan Mangles, an engineer at Keble, told Cherwell he believed “that the parents were easily deceived, and that the daughter put up an incredibly effective (and probably emotionally draining) deception.Given that the daughter apparently had a really broken relationship with them, I think it was incredibly careless of them to trust her with the money when they didn’t have any real trust emotionally.”Others were more impressed by Boardman’s thoroughness – Ben Steward, a historian at Lincoln told Cherwell, “It must surely have been quite a comprehensive effort even to give [her] some chance of succeeding in their deceit, as it’s no trivial matter to lie about!”last_img read more

LETTER TO THE EDITOR: CHARGES DMD DIRECTOR KELLY COURES IS RUDE

first_imgTO THE EDITOR OF CCO:I want to address a quote from DMD Director Kelley Coures that appeared in the Courier & Press that I find problematic. When referring to the ongoing revitalization of downtown he has been quoted as saying that he thinks that “one of the things the next City Council will have to do is find money to incentive construction of housing Downtown.”I take exception to his comment in several ways. First, it is not the job of a department head to tell the elected officials what they “have” to do. It is the job of our elected leaders to tell the department heads what they are to do in the public interest. Mr. Coures has a reputation for being rude to the public, and the Mayor appears to have no objection to how “the little people” are treated.The content of the quote is an even bigger sticking point for me. We have spent tens of millions of dollars to benefit the downtown area and will be paying that debt off for decades to come. We have all been told by the Mayor and Mr. Coures that those improvements will bring people back downtown to live. If that is true, and there is a market for middle-income housing in downtown, private development will handle that demand. We don’t incentivize subdivisions near the county line. We don’t need to because people want to live there. When people want to live downtown, builders will at least enjoy the fact that zoning will not be a problem and land prices are comparatively low, as well. Those and other natural incentives are nothing that City Council will have to “find.” I would also remind the gentlemen that if the hotel had not been so radically downgraded, there would be new apartments being built right now.As the election draws near, I hope the voters will step back and take a long, hard look at how the interests of the entire city have been served by Lloyd Winnecke and his employees. I don’t believe that Evansville can withstand another four years of Winnecke, much less Kelley Coures.Laura K. BlackburnFacebookTwitterCopy LinkEmailSharelast_img read more

Alastair Graham Walter Cameron

first_imgAlastair Graham Walter Cameron was born in Winnipeg on June 21, 1925, and died in Tucson on October 3, 2005. As a boy his interests ran to science fiction and away from sports. His father was head of the biochemistry department at the Manitoba Medical College; at the age of four Cameron addressed all men as “Doctor,” which he later said was an early example of forming a hypothesis based on limited data.His mother raised him by herself. Working his way through a private high school he became a bookie, taking bets from fellow students, and did quite well. In about 1941 he made a bet with a classmate that man would land on the Moon by the year 1970. Years later the classmate asked Cameron how he had known when the Apollo Program would take place. He replied that he had extrapolated the speed of transportation to the time when that speed would exceed that needed to escape from the Earth.He majored in math and physics at the University of Manitoba, and for his physics Ph.D. at the University of Saskatchewan, where he devised a new method to determine nuclear cross sections. He went on to apply nuclear physics to the origin of the chemical elements, or nucleosynthesis, in stars. In 1955 he married Elizabeth “Betsy” MacMillan. Betsy called Cameron “Alastair,” but in the scientific community he was known only as “Al.”After the Ph.D., Cameron spent two years at the Ames Research Center of the U.S. Atomic Energy Commission. While there he read that the astronomer Paul Merrill had observed a feature in the spectrum of a red giant star that corresponds to the chemical element technetium (Tc). Technetium has no stable isotopes; it was discovered in 1937 only after bombarding molybdenum with energetic particles; hence its name, derived from the Greek for “artificial.” Given the fact that technetium decays rapidly into other elements, Cameron reasoned that it must have been created in the star where Merrill found it. Cameron found this discovery “very exciting” because it provides a clue to the origin of the heavy elements in the Universe. Having never studied astrophysics before, Cameron immersed himself in the literature. In 1954 he relocated to the Chalk River Laboratory of the Canadian Atomic Energy Project, where he calculated cross sections for the many nuclear reactions that occur in the interiors of stars when the temperature is high enough for collisions between charged nuclei to overcome the electrical repulsion between them.The temperature at the center of the Sun is 14 million degrees, high enough to allow the conversion of hydrogen into helium, but not high enough for the reactions that ultimately lead to the creation of elements as heavy as Tc, that require hundreds of millions of degrees.While Cameron was working on nucleosynthesis, other theorists calculated that the Sun would run out of hydrogen in 5 billion years, at which time the temperature in its core would begin to rise, and the Sun would become a red giant star of the type that Merrill observed to contain Tc. Surprisingly, when stars run out of one nuclear fuel, their cores get hotter, not cooler, and then new fuels that react only at higher temperatures kick in. In red giant stars the helium produced earlier is reacting to form even heavier elements.Cameron predicted what elements are produced and in what quantities. He found that indeed technetium is produced along the way, explaining Merrill’s observation. In order to be found in the atmospheres of the Sun and other stars, and in solid bodies such as planets and meteorites, new elements have to first be ejected from the parent star into space where they contaminate interstellar matter destined to form new generations of stars and planets. Thus the full understanding of nucleosynthesis involves the formation of stars and planets, as well as the ejection of heavy elements into space by red-giant winds and supernova explosions. Undaunted by the challenge, Cameron plunged into a full range of theoretical astrophysics.Cameron published his papers on nucleosynthesis in 1957. Experts attribute the birth of the field of nuclear astrophysics to those papers, together with one by a group at Caltech led by William Fowler published the same year. Fowler, an experimentalist, won the Nobel Prize in 1983 for his work in the field, and in his Nobel Lecture credited the independent work of Cameron.In 1961 Cameron moved from Chalk River to the newly formed Goddard Institute for Space Studies in New York City. There he supervised graduate students at Columbia, New York University, and Yale. He taught regularly at Yale, where his students compiled his notes into a monograph that is highly regarded, but unfortunately, was never published. In 1973, upon the founding of the Harvard-Smithsonian Center for Astrophysics (CfA) at 60 Garden Street, Cameron was appointed to a professorship in the Department of Astronomy at Harvard. He also accepted a position as associate director of CfA for Planetary Science, a field to which his interests were increasingly turning because of the continuing discoveries of anomalous abundances of isotopes in meteorites. His model of the Solar Nebula, a disk of gas and dust formed at the time of the origin of the Sun 4.5 billion years ago, provides quantitative temperatures that theorists use in their studies of planet formation.During this period, Cameron is reported to have given a seminar at Caltech covering the entire history of the Sun and planets, from the collapse of an interstellar cloud to the coagulation of dust to form the solid cores of the planets. When asked what he did on the seventh day, Cameron replied, “I rested.”An important result of Cameron’s work was his conclusion that the main product of the buildup of the observed high abundance of the elements near iron in the periodic table is not iron per se, as had been assumed, but radioactive nickel 56. His idea was verified many years later by a NASA spacecraft.In 1982 Cameron became the chair of the Space Science Board of the National Academy of Sciences, which advises NASA on its science program, and at Harvard he served six years as chair of the Department of Astronomy. During this period he also organized annual conferences to bring together astrophysicists and planetary scientists to enhance collaborations between their different specialties.He then decided to attack a long-standing theoretical problem in planetary physics: the origin of the Moon. The Apollo Program had found that unlike the Earth, the Moon has no iron core, but is composed solely of the same material as the mantle of the Earth. At the time theorists could not explain this fact. Cameron proposed that the Moon formed from a disk of debris orbiting the Earth, much as the Solar Nebula orbited the Sun. But where could the debris have come from? Cameron proposed that it was material ejected from Earth’s mantle when a Mars-sized body collided with the Earth early in the history of the solar system. That would explain the Moon’s composition, but how would the debris reach the distance of the Moon? Cameron attacked this problem head on, acquiring faster computers for his office in order to model the collision event. He finally succeeded in showing that such a collision would result in a disk of the correct mass, as well as the angular momenta of the Earth and Moon that are observed today. Cameron’s theory is now the accepted one for the origin of the Moon.Cameron received honors from many scientific societies, among them the Petrie Prize of the Canadian Astronomical Society, the NASA Distinguished Service Medal, the Smith Medal of the National Academy of Sciences, the Hess Medal of the American Geophysical Union, the Leonard Medal of the Meteoritical Society, the Bethe Prize of the American Physical Society, and the Henry Norris Russell Lectureship of the American Astronomical Society—the highest honor an astronomer can receive.Upon his retirement from Harvard in 1999, Cameron accepted an appointment at the Lunar and Planetary Laboratory of the University of Arizona in Tucson. There he and Betsy lived in the Academy Village, a non-profit organization devoted to life-long learning. Sadly, Betsy, his loving wife of forty-six years, died in 2001; they had no children. Those of us who were lucky enough to know Al Cameron well remember him as an exceptionally talented and dedicated scientist, a wise counselor, and a witty person. Few are those who cross one’s path with all of these qualities; Al Cameron was one of them.Respectfully submitted,Alexander DalgarnoJames MoranDimitar SasselovPatrick ThaddeusFriedrich ThielemannGerald WasserburgJohn WoodGeorge Field, Chairlast_img read more
