A simple model of the convective internal boundary layer and its application to surface heat flux estimates within polynyas

first_imgA simple model of the convective (thermal) internal boundary layer has been developed for climatological studies of air-sea-ice interaction, where in situ observations are scarce and first-order estimates of surface heat fluxes are required. It is a mixed-layer slab model, based on a steady-state solution of the conservation of potential temperature equation, assuming a balance between advection and turbulent heat-flux convergence. Both the potential temperature and the surface heat flux are allowed to vary with fetch, so the subsequent boundary-layer modification alters the fluxconvergence and thus the boundary-layer growth rate. For simplicity, microphysical and radiative processes are neglected. The model is validated using several case studies. For a clear-sky cold-air outbreak over a coastal polynya the observed boundary-layer heights, mixed-layer potential temperatures and surface heat fluxes are all well reproduced. In other cases, where clouds are present, the model still captures most of the observed boundary-layer modification, although there are increasing discrepancies with fetch, due to the neglected microphysical and radiative processes. The application of the model to climatological studies of air-sea interaction within coastal polynyas is discussed.last_img read more

Comparative morphology of Southern Ocean Euphausia species: ecological significance of sexual dimorphic features

first_imgSpecies of the genus Euphausia dominate the euphausiid biomass of the Southern Ocean, the three largest being Euphausia superba, E. triacantha and E. crystallorophias. We measured a number of morphological features to identify differences between, and within, these species to obtain ecological insights. Interspecifically, the greatest difference was carapace size, with that of E. superba being by far the largest and most variable. This likely reflects its prolific spawning capacity compared with other euphausiid species. E. triacantha exhibited an extended sixth abdominal segment that could facilitate greater levels of thrust in the tail flip escape response. The pleopods, which provide propulsion in forward swimming, were more than 50% larger in E. superba, indicating a greater capacity for directional movement at high velocities. E. crystallorophias had eyes that were almost double the size of those in E. superba and E. triacantha, which may help retain visual resolution within its under-ice habitat. Intraspecifically, we found the above morphological features differed little between sexes and developmental stages in E. crystallorophias and E. triacantha, but differed significantly in E. superba. Compared to females and juveniles, male E. superba had significantly larger eyes and pleopods, whilst the carapace in males became shorter as a proportion of body length during growth. These features indicate a greater capacity for searching and swimming in males, which, we hypothesise, increases their ability to locate and fertilise females. This morphological specialisation in male E. superba is indicative of comparatively greater inter-male competition resulting from its tendency to form large, dense swarms.last_img read more

SGH2 Energy to build green hydrogen production plant in Lancaster

first_imgThe facility will feature SGH2’s pioneering technology, which uses recycled mixed paper waste to produce up to 11,000 kilograms (24,251 pounds) of green hydrogen per day SGH2 Energy to build green hydrogen production project. (Credit: Pixabay/Frauke Feind) Global energy company SGH2 Energy has announced its plans to build what it claims to be the world’s biggest green hydrogen production project in Lancaster.Under a recently signed a memorandum of understanding (MoU), the City of Lancaster will host and co-own the project.To be constructed on a 5-acre site, at the intersection of Ave M and 6th Street East, the facility will feature SGH2’s pioneering technology, which uses recycled mixed paper waste to produce up to 11,000 kilograms (24,251 pounds) of green hydrogen per day and 3.8 million kilograms annually.SGH2 said that this is nearly three times more than any other green hydrogen facility, built or under construction in the world.The commissioning of the project is scheduled in the final quarter of 2022Lancaster Mayor R. Rex Parris said: “This is game-changing technology. It not only solves our air quality and climate challenges by producing pollution-free hydrogen.“It also solves our plastics and waste problems by turning them into green hydrogen, and does it cleaner and at costs far lower than any other green hydrogen producer.”Construction work on the project is expected to begin in the first quarter of 2021 while the commission is scheduled in the final quarter of 2022.The project is planned to be completely operational in the opening quarter of 2023.The project is expected to create more than 600 jobs during the construction phase and upon completion it will create 35 permanent jobs.To develop and implement the project, a consortium of global companies and institutions that include Fluor, Berkeley Lab, UC Berkeley, Thermosolv, Integrity Engineers, Millenium, HyetHydrogen, and Hexagon have joined with SGH2 and the City of Lancaster.Recently, Dutch power company Eneco has joined oil and gas firm Neptune Energy’s project to develop what it claims to be the world’s first offshore green hydrogen project.last_img read more

City Council approves new Blavatnik building

first_imgThe Oxford City Council voted to pass the proposed plan for the Blavatnik School of Government building on Walton Street. This will be Oxford University’s biggest development project in a century. The project has received criticism from residents and groups affected by the construction in the past. Calum Miller, the Chief Operating Officer of the Blavatnik School of Government, issued a statement saying, “We are delighted that the Councillors have voted to approve our planning application. Throughout the consultation process, we made strenuous efforts to engage with the community and provide clear and detailed information to explain the rationale behind the building design and respond to concerns and questions raised.” The Jericho Community Association, an active local organization representing the historic suburban district of Oxford, have expressed their opposition. David Freud, owner of the Freud Cafe, which will neighbour the Blavatnik building, condemned the council decision as “a shocking travesty of the planning process” and said at the West Area Planning Committee meeting, “It was clear that a decision had already been made before the meeting had begun”. Freud’s objection stems from the blockage of light into the stained glass windows of the former St Paul’s church, now his cafe, by the proposed building. Another major concern is that the construction would disrupt half of the graves of patients who died at the former Radcliffe Infirmary, Oxford’s first hospital. Freud wrote on the wall of a Facebook campaign group named “Trouble in Wonder”, “My family has had the pleasure of caring for the former Church of St Paul for the past twenty-five years. If the Blavatnik School of Government is constructed, in the form currently proposed, on the burial ground of the former Radcliffe Infirmary, the Church and the protected nature of Jericho is in danger of irreparable damage.” The Blavatnik School of Government has responded to these concerns with a new information page regarding the building on its website. The school official told Cherwell “The Blavatnik School of Government’s planning application sets out in detail the faculty we have received from the Diocese of Oxford to exhume any remains found on the site. The remains will be exhumed with the utmost care and respect, in strict accordance with archaeological and Diocesan protocol, and laid to rest in consecrated ground.” Besides local protests, another controversy surrounding the building is its 22 meter height in violation of the city’s Carfax Height policy, which prohibits buildings taller than 18.2 meters within 1,200 meters of the Carfax Tower. Alison Stibbe, Head of Communications of the school, explained to Cherwell in an email, “The purpose of the Carfax Height policy is to prevent harm to Oxford’s skyline. A majority of Councillors agreed that our building would not harm the skyline and therefore the policy was not breached. Where it is visible, we believe it will be a positive and beautiful addition.” She added, “The Councillors were clear to stress that their decision on the Blavatnik School’s planning application does not set a precedent for future applications.” Jonathan Beddall, a current MPP student of Blavatnik said, “I am hugely excited by the new Blavatnik School of Government building as it combines cutting-edge architecture with world-class teaching space. The city council’s approval will enable the School to meet students’ needs whilst the School continues to grow.” He continues, “The new Blavatnik building is carfeully designed to respect the local area and is, in my view, a beautiful and sensitive addition to the City.” When asked about his feeling about the City Council decision and whether he will carry on the fight, Gideon Freud, campaign member and St John’s College student, replied that he had no further comments.last_img read more

Watch A Live Webcast Of Kanye West’s Easter ‘Sunday Service’ At Coachella [Stream]

first_imgToday, Easter Sunday, Kanye West will deliver the first-ever public edition of his ongoing Sunday Service events at Coachella. The 9:00 a.m. PT session in the Coachella campgrounds follows West’s surprise appearance during Kid Cudi’s Saturday set, which saw West and Cudi perform a few tracks from their collaborative 2018 project, KIDS SEE GHOSTS.The relationship between Kanye and Coachella has been particularly strained this year. While initially on the shortlist to headline the desert festival in Indio, CA, West was removed from the lineup when the festival reportedly refused to build him a special dome stage in the center of the festival grounds. Coachella chose to move forward without him, announcing a lineup topped by Childish Gambino, Tame Impala, Ariana Grande, and more.In the time since Coachella’s original 2019 Kanye plans were scrapped, West has kept busy with an interesting new project of his own, Sunday Service. Every Sunday for the last several months, the rapper/producer has hosted ultra-exclusive gatherings at which he delivers gospel-inspired performances with help from a full live band and gospel choir—all clad in angelic white (and sometimes black).Since the events have remained exclusive affairs, the public has only been able to experience Kanye’s Sunday Service via Instagram videos posted by attendees—a list that includes celebrities like rappers DMX and Kid Cudi, late-night host David Letterman, pop star Katy Perry, and many more.It appears the time apart has been good for Ye and Coachella. Now, even though there’s still no dome, all of Coachella (and everyone tuning in from home) will get the chance to join the congregation.

The next big things

first_imgBOSS MedicalWorking with Johns Hopkins researchers and physicians, M.B.A. students Romish Badani and Derek Poppinga have developed a minimally invasive device to extract bone grafts. If approved by the FDA, their product could transform spinal fusion procedures by reducing pain, cost, and medical error.MyTeksiMalaysian taxis, or “teksis,” are a traveler’s nightmare: wait times are long, customer service is poor, and passengers are frequently mugged or even killed. Harvard Business School (HBS) students Anthony Tan, Hooi Ling Tan, and Adeline Chan want to bring mobile technology to the growing industry that would match drivers and riders, enable mobile tracking, and allow customers to rate their service.Ubiquitous EnergyImagine if energy were as ubiquitous as paper. HBS’s Bart Howe, Harvard Graduate School of Design student Jutta Friedrichs, and researchers and students at the Massachusetts Institute of Technology have created SolSheets, disposable solar panels made of paper. The company hopes to transform energy markets in off-the-grid countries, and is in talks with Nokia to pilot its technology in Kenya.Sana CareMuch of the developing world now has access to mobile phones, but not to high-cost medical technology that could save lives. M.B.A. student Sidhant Jena and MIT researchers have developed low-cost wireless sensors and software that transform a smartphone into a portable electrocardiograph machine, a cheap diagnostic tool to catch cardiovascular disease.AppSuccessInspired by their experiences working in schools and education nonprofits, HBS and Harvard Kennedy School students Miki Litmanovitz, David Baron, David Shepard, and Andrew Offit (along with Harvard undergraduate Daniel Choi) developed a web-based platform to pair low-income high school seniors with college-student mentors, who will guide them through the college application and financial aid process.last_img read more

First Solar bounces back from slump expanding production and workforce in Ohio

first_img FacebookTwitterLinkedInEmailPrint分享The Blade:Three years ago, the mood around the First Solar Inc. complex in Perrysburg Township, Ohio was glum.The Tempe, Ariz.-based solar panel manufacturer announced the permanent layoff of about 450 employees as it phased out its older panels to make room for its new, larger Series 6 thin-film panels.The Series 6 went into production in mid-2018, and on Thursday the company commenced producing more of the Series 6 at a new plant that just opened in Lake Township.Their combined annual production capacity of 1.9 gigawatts — 600 megawatts at Perrysburg Township and 1.3 gigawatts at Lake Township, makes First Solar the largest solar manufacturer not just in the United States, but in the entire Western Hemisphere, the company said.The area workforce, which had dipped to around 800 after being just over 1,200, now stands at 1,400 employees.“Based on our customers’ needs, we have the ability to ship anywhere in the world. This added capacity positions us to expand our support within the U.S. solar sector with American-made manufacturing,” Jay Lake, a First Solar spokesman said via email.First Solar officials have always said that the Series 6, which is larger, more efficient, and up to 40 percent cheaper to manufacture than the older Series 4 panels, would be a game-changer for the company.Thin film technology, which is based on cadmium telluride, has a carbon footprint that’s up to six times lower than crystalline silicon solar panels made using conventional, energy-intensive production methods.The company is so convinced that the product will be a huge seller that it struck a deal with NSG Pilkington North America, a maker of sheet glass and the owner-operator of the Rossford glass plant, to invest $265 million to construct a 511,000-square-foot float glass plant in Wood County’s Troy Township.More: Three years after layoffs, First Solar producing like never before First Solar bounces back from slump expanding production and workforce in Ohiolast_img read more
