Trophic relations of the cephalopod Martialia hyadesi (Teuthoidea: Ommastrephidae) at the Antarctic Polar Front, Scotia Sea

first_imgSamples of the squid Martialia hyadesi were collected aboard two Japanese squid-jigging vessels carrying out commercial fishing trials at the Antarctic Polar Frontal Zone, north Scotia Sea, in February 1989. The dissected stomachs of 61 specimens were classified according to fullness and the contents were examined visually. Identifiable food items included fish sagittal otoliths, crustacean eyes, the lappets on euphausiid first antennule segments and cephalopod sucker rings. The most frequent items in the squid’s diet were the myctophid fishes Krefftichthys anderssoni and Electrona carlsbergi, the euphausiid Euphausia superba and a hyperiid amphipod, probably Themisto gaudichaudi. A small proportion of the sample had been feeding cannibalistically. Total lengths of the fish prey were estimated from sagittal otolith size using published relationships. All fish were relatively small; 7 to 35% of squid mantle-length. However, it is possible that some heads of larger fish are discarded by the squid and so are not represented by otoliths in the stomach contents. Over the size range of squid in the sample there was no relationship between size of fish prey and size of squid. Similarly, when the squid sample was divided into groups according to prey categories: crustaceans, crustaceans+fish, fish, cephalopod, there was no evidence that dietary preference was related to squid size. The prevalence of copepod-feeding myctophids in the diet of this squid, which is itself a major prey item of some higher predators in the Scotia Sea, suggests that a previously unrecognised food chain: copepod-myctophid-M. hyadesi-higher predator, may be an important component of the Antarctic oceanic ecosystem.last_img read more

Phased response of the subpolar Southern Ocean to changes in circumpolar winds

first_imgThe response of the subpolar Southern Ocean (sSO) to wind forcing is assessed using satellite radar altimetry. sSO sea level exhibits a phased, zonally coherent, bi‐modal adjustment to circumpolar wind changes, involving comparable seasonal and interannual variations. The adjustment is effected via a quasi‐instantaneous exchange of mass between the Antarctic continental shelf and the sSO to the north, and a 2‐month‐delayed transfer of mass between the wider Southern Ocean and the subtropics. Both adjustment modes are consistent with an Ekman‐mediated response to variations in surface stress. Only the fast mode projects significantly onto the surface geostrophic flow of the sSO, thus the regional circulation varies in phase with the leading edge of sSO sea level variability. The surface forcing of changes in the sSO system is partly associated with variations of surface winds linked to the Southern Annular Mode, and is modulated by sea ice cover near Antarctica.last_img read more

Alaskans protest Navy’s Northern Edge 2017

HPS���graduate program adds new hybrid track

first_imgNotre Dame’s History and Philosophy of Science (HPS) graduate program has added a new track in theology and science. The addition marks the first time HPS has offered a new track since its inception in 1990. HPS Director Don Howard said no other graduate program in the world produces Ph.D.s specializing in theology and science within the context of a history and philosophy of science program. “We want the products of this program to be the leading thinkers internationally about issues of science and religion,” Howard said. For Howard, the track speaks to Notre Dame’s Catholic intellectual mission. “Some people like to think of Notre Dame as America’s leading Catholic research university,” Howard said. “Well, you put those two terms together — Catholic and research — that’s just another way of naming theology and science as a topic that we should be doing more to address here.” Howard said the HPS program was “frustrated” when trying to appoint faculty members in the area of theology and science ten years ago. “The idea to occurred to us that, well, if we’re having trouble making a really high-impact, stellar senior faculty appointment because the talent is so thin, maybe we are approaching this from the wrong direction,” Howard said. The program instead focused on producing a new generation of experts working on theology and science. According to Howard, the job market for graduates of this track has improved. Howard said the Harvard Divinity School advertised an endowed chair specifically in theology and science. “We started to notice more and more schools that would mention theology and science or science and religion in a job ad,” Howard said. “Our own faculty having matured and developed some additional strengths and our having realized that there are really job opportunities out there, we just decided that now is the time to do it.” Howard said graduates of the track could also pursue positions at foundations like The Templeton Foundation, which funds research on theology and science issues around the world. As a result, Howard said graduates would help shape understanding and debate on theology and science, especially when the public frequently misperceives religion as divorced from science. “You often get this misleading impression that there’s a just science on one side and just religion on the other side, and that there’s no complexity in the debate,” Howard said. One misleading impression involves the Catholic Church’s position on evolution. For decades, Howard said, the church has embraced evolution as the correct scientific understanding of human origins. “The Catholic position has been that there has to be a place in that story for understanding the emergence of insouled human beings,” Howard said. “But again that’s not an impediment to the full embrace of evolution as the right scientific understanding of human origins.” Howard said HPS modeled the track after the existing tracks in philosophy and history. “This too is going to be an unusually intensive program,” Howard said. “It’s going to take tough and smart people to do well in this program, but we’re confident that we are going to attract those kinds of people into the program.” Gregory Sterling, dean of the Graduate School, was “enthusiastic” about the new track, which should produce two or three graduates every year. “More than an expansion of the total numbers, it will deepen the pool and help strengthen what is already a very fine program,” Sterling said. The addition of the track comes at a time when the school has undergone other changes. Sterling said The Kroc Institute has added several tracks, including peace and theology, in the last couple of years. According to Sterling, the school is determining the optimum size of every graduate program and whether they meet the needs of society. “We are taking stock of our programs and asking how should we change our programs to address the needs of the larger world,” Sterling said. While HPS will not offer courses in the track until the 2011 Fall Semester, Howard has already seen student interest. “I was surprised at how quickly I started getting inbound e-mails asking detailed questions about the program, asking for career advice about what you would do with this degree,” Howard said. “That’s just further confirmation of our sense that the world was ready for something like this.”last_img read more

Professors discuss ‘Sexuality 101’

first_imgIn response to a controversial upcoming lecture addressing sexual orientation and the Church, five Saint Mary’s professors presented their thoughts on this issue as part of “Sexuality 101” in Spes Unica Hall Thursday evening. Psychology professors Catherine Pittman, Rebecca Stoddart, Bettina Spencer, Religious Studies professor Stacy Davis and Global Studies professor Laura Elder defined sex, gender roles and sexual orientation and discussed the topic within an interdisciplinary context that included biological, environmental and cultural explanations for human sexuality. Pittman said the event, sponsored by the Psychology Department, provided a necessary source of information from the opposite side of a highly contested public debate that will come into focus during the Nov. 13 Theology on Fire lecture, titled “The Church and Same-Sex Attraction” and featuring Dr. Philip Sutton, a psychologist and marriage and family therapist. “When we learned about the lecture hosted by Campus Ministry, the Psychology Department was concerned about why he was chosen to represent the Catholic viewpoint,” Pittman said. Sutton’s approach to same-sex attraction therapy does not coincide with widely held views on the issue, Pittman said. “In the Psychology Department, we’re aware of what the standards of treatment are, and his [Sutton’s] practices are contrary to every organization that offers therapy,” she said.   The multifaceted nature of sexual orientation makes it difficult to study and draw conclusions, Elder said. Spencer said such controversial events as Sutton’s upcoming lecture often isolate lesbian, gay, bisexual, transgender and questioning (LGBTQ) students, so she encouraged the Saint Mary’s community to consider the importance of campus climate to LGBTQ students and how it impacts their college experiences.   Student Diversity Board President Maggie Galvin said the event prepared student attendees for Sutton’s visit to campus next week. “I thought this event was great and so informative.  Even if half of the girls who came tonight go to [Sutton’s] event they’ll bring educated and knowledgeable questions,” she said.

Sorin College fundraises for cancer research

first_imgThe sixth annual Kick-It for Kevin kickball fundraiser will be held on Saturday from 10:30 a.m. to 3 p.m. The tournament, which raises money to support pediatric and adolescent cancer research, will be held on Stepan Fields and Bond Quad.Junior Erich Jegier, game organizer for the event, said the annual tournament began in honor of Kevin Healey, a former Sorin College resident and member of the class of 2011.“His senior year of high school he was diagnosed with cancer, so he came … into Notre Dame with his cancer diagnosis, spent the majority of time while he was a student here in the hospital, even traveled to Boston to have a part of his lung removed,” Jegier said. “Then he passed away in 2009, and unfortunately lost his battle with cancer. So we hold this event every year in honor of Kevin to raise awareness … for pediatric and adolescent cancer. We hope to have fun and raise money for the cause at the same time.”According to Jegier, Kick-It for Kevin is the result of Sorin College’s partnership with a larger national organization, Kick-It, which holds kickball tournaments in various communities across the United States to raise money for childhood cancer research.Students can create a team for or donate to Saturday’s event by going to the Notre Dame Kick-It for Kevin page on kick-it.org“We’re asking people to get together teams of 10 to 12 to play, and as part of the game we’re asking people to raise a minimum of $20,” Jegier said. “You get to come play, eat lunch, there are games and prizes as well, but it is really fundraising for researchers to pursue their research in cancer.”According to Jegier, check-in for the preliminary matches will begin at 10:30 a.m. on Stepan fields. After each team plays two rounds on the fields the event will move to Bond Quad, where the semifinals and finals will be held.“We’ll have the stage set up, we’ll have speakers, we’re hoping to get … Fr. Monk Malloy, somebody from St. Joseph’s Children’s Hospital and Mary Kate Healey, Kevin’s sister, … to say a few words,” Jegier said.“We’re hoping to raise $10,000, which is a couple thousand more than we raised last year, so we’re always trying to grow and grow. I think we’re well on our way to that.”Jegier noted that Kick-It for Kevin’s recent Chipotle night raised just short of $1,500.“That was huge, a lot more than we expected,” Jegier said. “Now, this week leading up to the event, we’re pushing for people to ask parents, alumni, clubs to help support and donate.”Tags: Kevin Healey, Kick-It for Kevin, Sorin Collegelast_img read more

Notre Dame expands presence in Ireland with Galway program

first_imgNotre Dame International is giving students a chance to be their own “Galway Girl,” or “Galway Guy” if you prefer, with a new study abroad program in Galway City, Ireland. The first cohort of Fighting Irish, nine students in total, will be on the west coast of the Emerald Isle this coming fall.“You’re blazing this comet,” Lisa Caulfield, the director of the Notre Dame Global Center at Kylemore Abbey, said to the inaugural group of students. “You guys are on this first comet into Galway.”The Galway program immerses students directly into Irish society and culture. As in Dublin, students will take classes in the heart of a scenic Irish city and live on-campus at an Irish institution, in this case the National University of Ireland — Galway (NUIG).“The college itself is in the city of Galway and you’re basically on the Atlantic,” Caulfield said. “When we go up to Kylemore [Abbey], if you climb the mountain behind us, you’ll be looking over the Atlantic.”NUIG also offers classes for students in the College of Science, who have historically had fewer options for study abroad due to the limited programs that offer science courses. Students are taking advantage, with members of this group majoring in neuroscience, biology and pre-health, among other things. But besides classes, Caulfield says Ireland itself will teach the students a lot.“You’ll learn through the soles of your feet,” Caulfield said. “You’ll be immersed with the Irish culture and the landscape, and the two are really intertwined.”Studying in Galway will present a unique opportunity to explore the vibrant green landscape and culture of western Ireland. Cultural excursions include a “famine walk” that follows the paths of those devastated by the Great Famine, visiting a sheep farm, hiking the Aran islands and “pony trekking” on the famous Connemara ponies.“It’s these beautiful white ponies that dot the countryside,” Caulfield said. “They’re a social and economic contribution to that area that have been there for millennia. That’s true immersion, because you’ll be riding a pony that’s been reared in Connemara.”While the Galway study abroad program is new, the picturesque Kylemore Abbey Global Center, about 77 km outside of Galway City, has been a part of Notre Dame students‘ experiences in Ireland for the past few years. However, this will be the first time the castle will be close to a semester-long program.“The University of Notre Dame decided to partner with these amazing women of the Benedictine order that run the beautiful Kylemore Abbey, and we have renovated 10,000 square feet of this castle space,” Caulfield said. “The University is a part of this beautiful castle, and we’re really lucky that we have this anchor out west now.”NDI’s Dublin Global Gateway — the famous blue-doored O’Connell House — already attracts around 50 students a semester to Ireland, but Galway has its own charm, and a castle, Caulfield said.“It’s such a dramatic landscape. It’s very different from Dublin.” Caulfield says. “I feel like Galway is actually very different from any other city, and it’s been named the European Capital of Culture for 2020, so the whole of Europe has recognized Galway for being this very cultural city.”After doing the Ireland Inside Track, where she got to see a little bit of western Ireland and Kylemore Abbey, sophomore Jenna Koenig decided to go back for a whole semester via the new Galway program.“In Galway, it’s really easy to feel comfortable there. It feels more intimate.” Koenig said. “I wanted to study abroad somewhere I could get to know and somewhere I could be comfortable.”Koenig and others will be initiating the new program next fall, leading the way for other Fighting Irish to enjoy and engage in the distinct western Irish culture.“You’re actually making history for Notre Dame,” Caulfield said to the group. “In 20 years of offering a study abroad program in Dublin, you will be the first group out west.”Tags: Galway, Ireland, Kylemore Abbey, NDI, study abroadlast_img read more

Taiwan government moves to speed offshore wind projects

first_imgTaiwan government moves to speed offshore wind projects FacebookTwitterLinkedInEmailPrint分享Taiwan News:The government is sparing no effort in advancing offshore wind farm development through such measures as streamlining approval processes, strengthening oversight of support infrastructure construction, and providing assistance with planning and building procedures, according to Premier Lai Ching-te Transition to renewables is central to achieving a nuclear-free homeland by 2025, Lai said. Wind will play a key role in the nation’s energy mix, with the Ministry of Economic Affairs selecting nine local and foreign companies to build 14 wind farms with a total capacity of 5.5 gigawatts off Taiwan’s western coast within the next seven years, he added.MOEA Bureau of Energy statistics reveal that in 2017, 46.8 percent of Taiwan’s energy was generated from coal, 34.7 percent from natural gas, 8.3 percent from nuclear power and 4.5 percent from renewable sources. By 2025, the government aims to change these numbers to 50 percent for natural gas, 30 percent for coal and 20 percent for renewables, with solar and wind expected to contribute the majority of the latter.According to the MOEA, two demonstration wind farms in the waters off Miaoli and Changhua counties in northern and central Taiwan, respectively, are forecast to come online in 2019. Financed partially through state subsidies, the sites, which have a combined capacity of 230 megawatts, underscore the government’s commitment to fostering renewables and related expertise, the ministry said.The 14 additional offshore wind farms are projected to generate 19.8 billion kilowatt-hours of electricity per year, create 20,000 job opportunities, spur investment totaling NT$962.5 billion (US$31.56 billion) and reduce Taiwan’s carbon emissions by 10.47 million metric tons annually, the MOEA added.More: Cabinet accelerates offshore wind farm development in Taiwanlast_img read more
