Simultaneous measurements of the O2(¹Δ) and O2(¹Σ) Airglows and ozone in the daytime mesosphere

first_imgWe report simultaneous measurements of the O2(¹Δ) and O2(¹Σ) airglow volume emission rate profiles in the daytime mesosphere. We use these measurements to derive ozone concentrations separately from each airglow. The measurements were made as part of the Mesosphere‐Thermosphere Emissions for Ozone Remote Sensing (METEORS) sounding rocket project launched from White Sands Missile Range, New Mexico. These data offer the opportunity to assess the consistency of ozone profiles derived from measurements of the oxygen airglows and thus provide a fundamental test of our understanding of dayglow physics and solar energy deposition. In both airglow‐derived profiles the ozone decreases with altitude throughout the middle mesosphere and a pronounced secondary maximum exists near 90 km. The derived ozone profiles are in agreement to within measurement uncertainty. This agreement confirms that the major processes responsible for the generation of mesospheric oxygen dayglow are well understood via measurement.last_img read more

Acute oil exposure reduces physiological process rates in Arctic phyto- and zooplankton

first_imgArctic shipping and oil exploration are expected to increase, as sea ice extent is reduced. This enhances the risk for accidental oil spills throughout the Arctic, which emphasises the need to quantify potential consequences to the marine ecosystem and to evaluate risk and choose appropriate remediation methods. This study investigated the sensitivity of Arctic marine plankton to the water accommodated fraction (WAF) of heavy fuel oil. Arctic marine phytoplankton and copepods (Calanus finmarchicus) were exposed to three WAF concentrations corresponding to total hydrocarbon contents of 0.07 mg l−1, 0.28 mg l−1 and 0.55 mg l−1. Additionally, the potential phototoxic effects of exposing the WAF to sunlight, including the UV spectrum, were tested. The study determined sub-lethal effects of WAF exposure on rates of key ecosystem processes: primary production of phytoplankton and grazing (faecal pellet production) of copepods. Both phytoplankton and copepods responded negatively to WAF exposure. Biomass specific primary production was reduced by 6, 52 and 73% and faecal pellet production by 18, 51 and 86% with increasing WAF concentrations compared to controls. The phototoxic effect reduced primary production in the two highest WAF concentration treatments by 71 and 91%, respectively. This experiment contributes to the limited knowledge of acute sub-lethal effects of potential oil spills to the Arctic pelagic food web.last_img read more

Another Remus 100 UUV for US Navy

first_img View post tag: Defense April 24, 2013 U.S. Navy undersea warfare experts are buying another REMUS 100 unmanned underwater vehicle (UUV) from Hydroid Inc. in Pocasset, Mass., a wholly owned subsidiary of Kongsberg Maritime AS in Kongsberg, Norway.The Naval Undersea Warfare Center (NUWC) in Newport, R.I., needs the Hydroid REMUS 100 for continued development and testing, supplementing NUWC’s existing inventory of REMUS systems acquired previously to support a variety of program efforts, NUWC officials say.The NUWC is The Navy’s primary research and engineering center for underwater and submarine warfare.REMUS is short for Remote Environmental Measuring Unit S. The REMUS 100 slightly longer than five feet, is 7.5 inches in diameter, and weighs 85 pounds. It can operate to depths of 328 feet on missions lasting eight to 10 hours.Powering the REMUS 100 UUV is a direct-drive DC brushless motor and an open three-bladed propeller. It can swim as fast as 4.5 knots and navigates by Doppler-assisted dead reckoning, Inertial navigation system, and GPS.Operators control the REMUS 100 UUV with laptop computer-based software for programming, training, post-mission analysis, documentation, maintenance, and troubleshooting. The software enables one operator to control as many as four REMUS 100 UUVs at the same time.The REMUS 100 is suited to marine research, defense, hydrographic and offshore energy applications. It is small enough to be carried by two people, and can perform intricate sonar and oceanographic surveys over large areas, Hydroid officials say.Typical REMUS 100 applications include mine countermeasures, harbor security, debris field mapping, search and salvage operations, hydrographic surveys, environmental monitoring, fishery operations, and scientific sampling and mapping, Hydroid officials say.NUWC is buying the REMUS 100 UUV sole source because Hydroid is the only known source that can meet Navy requirements of a UUV that is man-portable, has an energy density of at least 1.2 kilowatt hours, Navy officials say.Researchers plan to use the REMUS 100 in exercises that require a UUV that can move as fast as four knots for as long as 10 hours. NUWC officials plan to release a formal request for quote (RFQ) to Hydroid around 1 May.[mappress]Naval Today Staff, April 24, 2013; Image: Kongsberg View post tag: UUV View post tag: Defence View post tag: REMUS View post tag: ANOTHER Another Remus 100 UUV for US Navy View post tag: 100center_img View post tag: Naval View post tag: Navy View post tag: News by topic View post tag: US Back to overview,Home naval-today Another Remus 100 UUV for US Navy Training & Education Share this articlelast_img read more

Three chords and some Kierkegaard

first_imgThis article is part of a series on the impact of humanities studies in and out of the classroom.Storytelling has been a part of Brynn Elliott’s identity since she was a child, when she made up interpretive dances around her house and directed plays with her family’s nativity set. Coming to Harvard was an extension of that narrative.“I wanted to research songs,” said Elliott ’18, who started guitar at 16 and performs with a self-titled band. “I have written very personal songs, but the songs I’m most proud of are rooted in a deeper tradition than my own life.”The scholar-rocker got serious about music a year before arriving in Cambridge. In 2013, her name on Harvard’s wait list, Elliott left her Atlanta home to take an internship with music producer Clif Magness (Avril Lavigne, Kelly Clarkson) in Portland, Ore., recording a series of songs that included the Tolstoy-inspired “Dear Anna.”“At that time, the music was very singer-songwriter, countryish,” she said. “Now it’s pop-rock.”When Harvard accepted Elliott, who lives in Currier House, she brought along her guitar and a commitment to keep the band (most of whom are based in Los Angeles) going. They tour in summer, through winter break, and on some fall and spring weekends, totaling 70 concerts a year. This past summer, she released an EP titled “Jungle.”Philosophy courses have provided much of the inspiration for Elliott’s lyrics. In “Faith and Authenticity: Existentialism and the Human Condition,” she shifts between Kierkegaard and Sartre.“I get the artistic freedom of expression in my songwriting,” said Elliott. “It challenges me to think in a new way.”In the spring, Alison Simmons, the Samuel H. Wolcott Professor of Philosophy, taught Elliott in “Beyond Dualism,” on 17th-century female philosophers, and found a student “constantly thinking through how the ideas and especially the ideas of people from history might help her make sense of her own experience, which, in turn, helps her communicate through her music.”“Her education is part of her art making,” Simmons said. “We’ve talked a good deal about her career. Some would like her to leave school to pursue her music full-time. But that would be like saying to Jimmy Page, ‘Unplug your electric guitar and we’ll go on the road without your power source.’ Thinking through complex — and even some bizarre — ideas in class is Brynn’s power source. Maybe when she wins an award Descartes will get a shout-out.” A monstrous passion Related In ‘Beowulf’ and other dead-language texts, junior finds enduring inspiration Carving out a music career while keeping up with her philosophy studies might seem like an identity split, but Elliott feels deeply rooted in both.“Pop music has lost its humanism,” she said. “There’s this whole sterility. If there’s not a human connection in that, it’s just going to be a fad. I’ll write songs that have a techno flair, but that are rooted in a tradition because it’s connected with people.”She’s the only student in a band of full-time musicians, which allows her to “be connected with people on stage, making sounds that primarily are not electronic.” Those collaborations, as well as the connections she’s made in the classroom, have been critical for Elliott, who came to Harvard having been homeschooled all of her life.“I didn’t have people I was learning with,” she said. “It sounds cliché, but not having exposure to other perspectives — what that means is that you don’t necessarily get a diverse set of opinions. Here my mind has just expanded so much, and I’ve translated that into my music.”She recalled going as a freshman to Simmons’ office hours, wanted to discuss a disappointing grade on one of her first papers.“I sat down and she was like: ‘How are you?’” Elliott said. “I started talking about the paper, and she said, ‘No, no, no. How are you doing?’ She was really trying to engage me. We’re all human and that’s kind of the most important thing to keep in mind when we’re writing papers, or writing music, or doing a club. That’s a big thing she’s taught me.”last_img read more
