Seeking clues about sea level from fossil beaches

BREDASDORP, South Africa -- A scruffy crew of scientists barreled down a dirt road, their two-car caravan kicking up dust. After searching all day for ancient beaches miles inland from the modern shoreline, they were about to give up.

Suddenly, the lead car screeched to a halt. Paul Hearty, a geologist from North Carolina, leapt out and seized a white object on the side of the road: a fossilized seashell. He beamed. In minutes, the team had collected dozens more.

Using satellite gear, they determined they were seven miles inland and 64 feet above South Africa's modern coastline.

For the leader of the team, Maureen Raymo of Columbia University, the find was an important clue as she tries to determine just how high the oceans might rise in a warmer world.

The question has taken on new urgency in the aftermath of superstorm Sandy, which caused coastal flooding that scientists say was almost certainly worsened by the modest rise of sea level over the past century. That kind of storm tide, the experts say, could become routine along American coastlines by late in this century if the ocean rises as fast as they expect.

In previous research, scientists have determined that when the Earth warms by only a couple of degrees Fahrenheit, enough polar ice melts, over time, to raise the global sea level by about 25 to 30 feet. But in the coming century, the Earth is expected to warm more than that, perhaps 4 or 5 degrees, because of human emissions of greenhouse

Experts say the emissions that may make a huge increase of sea level inevitable are expected to occur in just the next few decades. They fear that because the world's coasts are so densely settled, the rising oceans will lead to a humanitarian crisis lasting many hundreds of years.

Scientists say it has been difficult to get people to understand or focus on the importance, for future generations, of today's decisions about greenhouse gases. Their evidence that the gases represent a problem is based not just on computerized forecasts of the future, as is commonly believed, but on what they describe as a growing body of evidence about what occurred in the past.

To add to that body of knowledge, Raymo is studying geologic history going back several million years. The Earth has warmed up many times, for purely natural reasons, and those episodes often featured huge shifts of climate, partial collapse of the polar ice sheets and substantial increases in sea level.

"I wish I could take people that question the significance of sea level rise out in the field with me," Raymo said. "Because you just walk them up 30 or 40 feet in elevation above today's sea level and show them a fossil beach, with shells the size of a fist eroding out, and they can look at it with their own eyes and say, 'Wow, you didn't just make that up.' "

Perth beaches get $70m revamp

Premiere Colin Barnett announces the redevelopment at Scarborough Beach. Picture: Kerris Berrington Source: PerthNow

THREE Perth beaches will be revamped with a $70 million state government investment that will see roads realigned to keep heavy traffic away and picnic areas established.

An initial contribution of $30 million has been provided to transform Scarborough beach and its surrounding areas.

Up to $40 million has also been set aside for the realignment of Curtin Avenue, south of the Marine Parade roundabout in Cottesloe, which will assist Leighton and Port beaches.

Premier Colin Barnett said the Scarborough works would include the beachfront, as well as the entire precinct through a collaboration between the Metropolitan Redevelopment Authority, the City of Stirling and the private sector.

"Scarborough is a favourite tourist destination, but the area has recently suffered from a lack of new investment and a poor reputation, so this decision will help fulfil its enormous potential as one of the nation's best beaches," he said.

Works will include new pedestrian promenades along the beachfront, cycling paths, landscaping, a children's playground, public art, fitness equipment, barbecues, seating and shade along the beach, and improvements to access and car parking.

Mr Barnett said realigning Curtin Avenue, so it ran along the railway line and drew heavy traffic away from Leighton and Port beaches, would also open up more land.

"While there have been many improvements in the last decade at Leighton Beach, the Leighton Marshalling Yards remain a barren wasteland and potential danger for beachgoers," he said.

"The realignment of Curtin Avenue south of the Marine Parade roundabout will completely open up the area and bring back families and beachgoers to a revitalised beachfront.

Transfer Students in Science Majors: Would you like to talk about your transfer experience at the university?

This is a research project about transfer students from a community college; I am asking students about their transfer experience to the university.

To participate, the requirements are: 1) You are a prior community college student who completed either an AGEC or an Associate of Science at a community college. 2) You are enrolled in a Science major at the UA. 3) You must have completed at least ONE semester (with graded units) at the UA. 4) You must be over 18 years old.

Participation consists of an interview of about ten questions about your college transfer experience, and completing a short survey. The interview is designed to take about 30 minutes, and can be done on campus at a time and location convenient for you during January and February 2013.

You will be compensated for your participation at the time of the interview.

If you are at all interested in participating, please reply to Ruthann at rtcoyote@email.arizona.edu or call me at (520) 256-0441 immediately. Replying does not fully commit you; it simply indicates your interest. I anticipate that possibly more students will want to participate than I will be able to accommodate, so interviews will be scheduled on a first-come, first-serve basis.

An Institutional Review Board responsible for human subjects research at The University of Arizona reviewed this research project and found it to be acceptable, according to applicable state and federal regulations and University policies designed to protect the rights and welfare of participants in research.

Trailblazing CLU biology professor leaving classroom after 50 years

Barbara Collins, who is leaving the classroom after 50 years of teaching microbiology and botany at California Lutheran University, has blazed some trails in hertime.

Over the years, leading field trips from local parks to New Zealand, Collins has earned a reputation for charging ahead on the trail, sometimes leaving her students breathlessly trying to catchup.

Collins also has been a trailblazer in her career, working full time as a professor while bringing up fivechildren.

"She's a force of nature," said David Marcey, a biology professor at CLU. "She's maintained an active role in teaching and in field studies, often outpacing her 19-year-old students up the mountain. ... She's reallyirreplaceable."

Collins, 83, has contracted an incurable, progressive lung infection that makes it difficult for her to breathe and left her weighing less than 90 pounds. She will retire this year, a decision she resisted but has reluctantlyaccepted.

"I could teach sitting down, but working in the lab, I wouldn't have the breath to go around and get the work done," she said. "At first, it was really hard, but after the last hospital visit, I realized I really couldn't do it. ... I don't know what the future is, but we just go ahead and do whatwecan."

Collins still shows up at her office most days, working on a project to identify trees and shrubs on campus. She's also planning on writing a book about living life in your80s.

That's typical of Collins.

(View the Trailblazing CLU biology professor slide show.)

When she was pregnant back in the 1960s, her department chairman said Collins would have to stop teaching. Collins would have none of it, telling the chairman that if her students had never seen a pregnant woman, it was about time they did. She went on to receive the President's Award for Teaching Excellence in2007.

NU Regents approve center for brain, biology, behavior

The University of Nebraska Board of Regents approved the Center for Brain, Biology and Behavior as an interdisciplinary research center at the University of Nebraska-Lincoln on Friday.

The center is a key component of an emerging collaboration between athletics and research at UNL. Known as CB3, it will be located later this year in half of a 50,000-square-foot research area in the East Stadium addition to Memorial Stadium.

CB3 will house a radiology unit and a state-of-the-art functional magnetic resonance imaging magnet, which will enable faculty and students from a wide spectrum of disciplines to conduct research related to behavior and performance, including the study of concussions.

"CB3 builds on our strengths in concussion research and its strong multidisciplinary emphasis will position UNL as a leader in research on the brain, biology and behavior," said Prem S. Paul, UNL vice chancellor for research and economic development, in a written statement. "This center is at the heart of a unique partnership between our prestigious academic and athletic programs."

The center will occupy space in the south half of the East Stadium addition, while the north half will be dedicated to the Nebraska Athletic Performance Lab. The research facility also will provide shared space, including 48 laboratories and a common area large enough to accommodate 40 to 50 people.
