first_imgTwo sediment cores from the deep-sea Murray Canyons area, south of Kangaroo Island, Australia were investigated for quantity and composition of terrigenous material. Spanning the last 175 ka, terrigenous matter from these cores provides evidence for changes in sea level and palaeoclimate of the adjacent Australian continent. Located offshore Australia’s major river system, the Murray-Darling, the sediment cores record varying inputs of suspended river clays. High input prevails during glacial periods, when sea level is low and the river discharges directly at the edge of the continental shelf Today, and during previous periods of high sea level, the Mouth of the River Murray is more than 200 km away from the core sites, sedimentation of terrigenous matter is reduced and consists primarily of aeolian dust. However, even during periods of high sea level in the early Holocene (11-6 ka), river clays reached the core site, indicating a stronger discharge from the Murray and more humid conditions in the catchment area. The present mode of low-input aeolian sedimentation over the core sites was only established 4 ka ago. Differences in composition of the river clays between the penultimate glacial (isotope stage 6) and the last glacial maximum (isotope stage 2; LGM), as well as different clay mineral assemblages between the two cores during the LGM suggest that palaeodrainage on the exposed shelf varied between sea level lowstands. Minute changes in shelf morphology could have prevented the “Palaeo-River Vincent”, a river which drained the glacially dry Gulf St. Vincent, from joining the course of the Murray during the LGM. Clay mineral evidence suggests that this palaeo-river did join the Murray during the penultimate glacial and significantly altered the clay mineral signature from the Murray-Darling catchment area.last_img read more

first_imgWith Dead & Company tour in full swing, band members Bob Weir and John Mayer sat down with the Asbury Park Press ahead of the band’s New Jersey debut. The two guitarists talk extensively about building a large musical catalog with diverse influences, and how each are astute in hearing these influences and learning from one another.“When John plays blues, you can hear what subgenre he’s going for,” said Weir. “He’s real well-versed in particularly that idiom, but what that told me is that he’s basically a student and fan of American musical heritage.”He continued, saying “I could hear (Mayer’s) appreciation of the various fields, and that’s where our music comes from… We grew up — the guys in The Grateful Dead — grew up in an era in the Bay Area out here, where you had everything that America had to offer on the radio. And we were the kinds of kids who were just playing the buttons on the radio.”“If there was something playing that wasn’t catching our interest, we hit another button. We’d go from rock ’n’ roll to jazz to R&B or blues stations, classical music – whatever it took to grab our attention… And we were all different guys, but we all had that same approach, most particularly Jerry and I.” It seems Mayer has a similar mindset, something that Bob Weir finds endearing. Mayer chimed in about his own influences and mindset for building a diverse repertoire. “When you’re into music the way that Bob and I are, and you know, we’re separated by a lot of geography, a lot of time, but there’s a certain way to be in the music where it’s almost like collecting baseball cards… It’s like you collect the Texas blues card. You collect the Chicago electric blues card. You collect the country-western card.”“And it’s sort of like this love of all these different little cards you can collect and keep in a little stack and walk around with them in your back pocket.  It really for me was just about like sort of just getting another card or trading a card, you know?  And when musicians look at music that way, where it’s just sort of like this Rolodex of influences, it’s actually really great to have that conversation musically, and it’s just a matter of rearranging the cards a little bit.”That’s really part of the Grateful Dead magic, being able to go from folk to blues to funk in the drop of a hat. With these two guitarists up in front and the supreme talents of musicians like Bill Kreutzmann, Mickey Hart, Oteil Burbridge and Jeff Chimenti, there’s plenty of magic left to come!last_img read more

first_imgThe USC Stevens Institute for Innovation recently released a report that addresses appropriations for university research, a key point in Obama’s State of the Union speech last week.[Correction: A previous version of this article said the report released by the USC Stevens Institute for Innovation addressed problems in university research. The report focuses on the role of university research in policymaking. The Daily Trojan regrets the error.]The “Universities in Innovation Networks: The Role and Future Promise of University Research in U.S. Science and Economic Policymaking” is the fourth report in the Doing What Works and Science Progress projects at the Center for American Progress.Innovation · The Annenberg Innovation Lab, which opened in fall 2011, is an example of innovative research occurring at USC, according to the Stevens Institute. – Chris Roman | Daily TrojanLed by Vice Provost for Innovation and Executive Director of the USC Stevens Institute for Innovation Krisztina Holly, the report highlights the resources available at universities to stimulate growth and greater competitiveness for the country.“Higher education plays a hugely important role in driving the economy,” Holly said. “Each year, universities get federal funding for research, and all of this can translate into products, companies and jobs.”In the report, Holly addresses the ways in which federal policies and capacity for university research are tied together and outlines five recommendations to improve federal research and development policy so that universities can achieve their potential to spearhead innovation in key industries.Melissa Lechner, a graduate student studying medicine in a PhD and MD program, said her work in cancer research can be attributed to the support she received from the university.“The goal is to improve outcomes for patients,” Lechner said. “USC allowed me to take discoveries in basic science and translate it to patients in a rapid manner that wouldn’t have been possible on my own.”Some of the challenges with the broader field of innovation involve measuring the impact, as it changes rapidly, and the perceived risk. But,as students try to prepare for the progressive workforce in this current economic and political climate, many are stepping up.The USC Stevens Institute is just one of the many unique features at USC that are involved with promoting this innovation culture.“These programs that are university-wide are aimed to nurture the culture of helping to transfer ideas to make an impact,” Holly said.The USC Stevens Institute is also host of the USC Student Innovators Showcase during Trojan Family Weekend.Ranging from projects on real-time cinema analysis of the presidential campaign to research on public interactive exhibits, the Annenberg Innovation Lab was created in 2009 to support students and faculty in their interdisciplinary efforts.As the technology manager who works closely with student team projects, Dale MacDonald said, “The entity itself is an innovation and is going to lead to profound, transformative change along the way.”Noting its charter to follow processes of innovation inspired by culture other than just technology, MacDonald encourages students to take advantage of opportunities like CRUNCH, the lab’s yearly design competition for USC students and alumni with a $30,000 prize.Similarly, the Graduate Student Government hosts a yearly Poster Symposium that will soon include a website component to showcase innovative research done by USC graduate students across all departments and judged by USC faculty.GSG Academic Affairs Director Jaclyn Selby, a graduate student studying global media and tech policy, said, “The point is so that people can see the best research at USC beyond what they know at their own department.”If all it takes is an idea, students and faculty are right where they need to be to take advantage of some of the most forward thinking research and learning opportunities.  Holly said there are many opportunities in Los Angeles.“Keep your eyes open,” Holly said. “Students should be excited by the potential to work on the next new thing.”last_img read more
