UA engineers help find site to drill for Antarctica’s ancient ice

TUSCALOOSA, Ala. — A unique radar developed by engineering researchers at The University of Alabama helped find the location to recover some of the oldest ice buried in Antarctica as part of an international effort to better understand the Earth’s climate history.

Using information collected by the radar, scientists leading the project confirmed the site where they intend to drill a core of ice in East Antarctica, located at Little Dome C, an area of about six square miles nearly 620 miles inland. It is possible the drilling will recover ice nearly 1.5 million years old, which may reveal why the climate cycle for the Earth’s ice ages lengthened roughly 1 million years ago.

“With active participation of UA students, our team developed very complex, high-sensitivity remote sensing radars in less than a year and successfully mapped deep layers no other group has been able to accomplish,” said Dr. Siva Prasad Gogineni, Cudworth Professor of Engineering, director of the UA Remote Sensing Center, and an internationally recognized expert in the field of remote sensing.

Dr. Stephen Yan, assistant professor of electrical and computer engineering, led the project for UA.

The work is part of Beyond EPICA, a more than $12 million project supported by the European Union involving 12 institutions in 10 European countries and with UA selected to perform precise radar imaging. It follows a previous effort, dubbed EPICA, which recovered an 800,000-year-old ice core.

Scientists, led by Dr. Carlo Barbante from Ca’ Foscari University of Venice and the Institute of Polar Sciences of the National Research Council of Italy, hope ice layered 1.5 million years ago can reveal Antarctica’s climate and the greenhouse gasses present during the Middle Pleistocene Transition, which happened between 900,000 and 1.2 million years ago.

During this time, the periods between glacial climates transitioned, lengthening from about 41,000 years to 100,000 years between ice ages. This change is the mystery Beyond EPICA seeks to resolve.

Little Dome C, nearly 25 miles from the nearest research station in an area administered by the French and Italian polar agencies, was selected as the potential site to recover the ancient ice after an initial two-year Radar Echo Sounding survey that covered more than nearly 2,500 miles of airborne and ground-based measurements as part of the previous EU project.

In November, UA’s radar was deployed to the site to scan nearly 2 miles below the ice to precisely select the exact drilling site. The work was conducted by Dr. Drew Taylor, UA assistant professor of electrical and computer engineering, with international collaborators Dr. Daniel Steinhage from the Alfred Wegener Institute in Germany and Dr. David Lilien from the University of Copenhagen in Denmark.

The ultra-wideband radar and antenna capable of penetrating deep into ice was able to image, with high definition, the ice layering in the deepest part of the ice sheet. The radar was designed and fabricated by UA researchers, including seven graduate and eight undergraduate students in the UA College of Engineering, and led by Dr. Charles O’Neill from the UA Remote Sensing Center.

Radar development was supported by the University of Copenhagen, the Alfred Wegener Institute, the National Science Foundation and UA.

The radar was previously used in Greenland as part of another international effort to unveil ancient climate history and to provide perspectives on improving climate models.

“We’re proving we have the expertise in remote sensing with our radar systems and design to provide unique solutions to answer the questions the scientists have about the ice and our climate,” Taylor said.

Taylor and the team at Little Dome C drove a tightly spaced grid over two areas about 2.5 square miles in size. The radar collected a tremendous amount of data initially analyzed on-site using software developed by students and faculty from UA.

“It became apparent to everyone these data were much improved from anything seen before in this area,” Taylor said. “It is a testament to the effort put forth by the leadership, faculty, staff and students of the Remote Sensing Center over the past weeks and months.”

The data was further analyzed and modelled in European laboratories, allowing scientist to confirm with a meter-scale resolution the exact future drilling site. The radar imaging showed there should not be any ice melting at the base, despite the tremendous pressure of the mass of ice above it. The characteristics of the deeper layers, with ice at least 1.5 million years old, should be preserved with a good temporal resolution, the scientist believe.

“It is the first time that a site for deep drilling has been selected with such a high precision and effort,” said Dr. Olaf Eisen with the Alfred Wegener Institute and one of the leaders of the Beyond EPICA project. “The new radar measurement showed more clearly than before, that the ice there is well stratified and most probably very old.”

If the project proceeds according to plan, it will take six years to drill, collect and analyze the ice from what will be a deep hole.

He was arrested Saturday on charges including drug possession, assault and evidence tampering.

Police tell news outlets that Glasgow struggled with an officer who tried to arrest him after finding crack inside his pocket.

Glasgow has worked for years to register prisoners to vote inside Alabama jails and prisons.

He was charged with capital murder in 2018 after a fatal shooting but was out on bond.

He’s the half-brother of nationally known activist Al Sharpton.

Hurts: Time back in Alabama going ‘really well’ — ‘Love’ for Bama will ‘never go away’

MOBILE — The Senior Bowl Week Media Day was held on Tuesday at the Arthur R. Outlaw Convention Center, and former University of Alabama Crimson Tide quarterback Jalen Hurts had droves of reporters on hand hoping to capture yet another classic Hurts press conference. The humble Hurts did not disappoint.

To kick off his remarks, Hurts commented once again on being back in the Yellowhammer State. He, of course, played at Oklahoma this past season as a graduate transfer from Tuscaloosa. Hurts finished as the runner-up in the 2019 Heisman Trophy voting.

“I think being here and being back in this state is [going] really well. I’m having this opportunity to play in this game and showcase my abilities and show what I’m made of. I’m thankful for it, I’m appreciative of it. And I’m ready to attack it,” Hurts said.

Asked on a follow-up question to compare the Alabama and Oklahoma fanbases, he responded, “I have a lot of respect for both universities. Both have rich tradition, history. I appreciate all the support.”

The quarterback would later say both programs have “great coaches.”

Of the universities, Hurts added, “The appreciation I have for them both, the love I have for them both, it’ll never go away. The way that they’ve accepted me, both schools, not many people can say that they’ve experienced that or they have that … so I’m thankful for it.”

Hurts said that during Senior Bowl Week and in the game on Saturday, he simply wants to “be the best version of” himself. He listed executing, learning and being a “student of the game” as priorities.

The former Tide star was also asked if he has had the opportunity to visit with the outgoing Bama players at the Senior Bowl, his former teammates Jared Mayden, Terrell Lewis, Raekwon Davis and Anfernee Jennings.

“Yes, sir,” Hurts answered. “It’s been well [sic]. Great seeing them. Good to be out there on the practice field with them again. I think they have the same approach I have in terms of maximizing this opportunity.”

Hurts later quipped that he plays with “a boulder” on his shoulder rather than merely “a chip.”

Asked about the reception he expected back in the state of Alabama and what it has been like so far, Hurts commented, “It’s been pretty hectic so far — in a good way. Just being back here, a lot of love. I’m appreciative of it all.”

“I get on the elevator, one of the workers at the hotel we’re staying at — she let me have it in terms of just screaming,” he continued with a smile. “‘Jalen Hurts is really on my elevator,’ just stuff like that. That’s special to me, and I know it won’t be like that forever. I’m just soaking it all in.”

Byrne: Impeachment is nothing to smile about

For three years now, the American people have been forced to endure the efforts by Democrats and the liberal mainstream media to impeach President Trump and remove him from office in the face of his clear electoral victory in 2016. They have tried everything, from a needless special prosecutor investigation, which resulted in nothing, to an Adam Schiff-coached whistleblower who admitted he had no firsthand information and relied on news articles by that same liberal media.

The farce produced just two articles of impeachment, neither of which alleges “treason, bribery or other high crimes and misdemeanors” as required by the Constitution. An unprecedented and totally partisan process in the House produced nothing that Democrats could even allege is impeachable.

533

Then Nancy Pelosi, after insisting for weeks that impeachment couldn’t wait and had to be done by Christmas, held onto the articles, refusing to send them to the Senate as is required. This prolonged the spotlight on her, as the ever-worshipful liberal media gushed over her political brilliance, ignoring the inconvenient fact that her strategy of forcing the Senate to adopt her preferred process for the trial completely failed.

The Constitution is clear. While the House has “the sole Power of Impeachments,” the Senate has “the sole Power to try Impeachments.” And the Constitution clearly states that each house of Congress sets its own rules. Pelosi had no right or power to dictate trial rules to the Senate. Her behavior was unconstitutional and brought embarrassment and dishonor on the House. So, I filed a resolution censoring the speaker for her inappropriate behavior.

Finally, last week as Democrats began to abandon Pelosi’s position, she relented, and the House appointed seven “managers” to present the House’s articles and “case” to the Senate. Led by Schiff, who literally made-up words for the transcript of President Trump’s call to the President of Ukraine in his first day of impeachment “hearings,” and by the bumbling and incompetent Jerry Nadler, the House managers will finally have to behave according to the rules of a truly fair process, presided over by the Chief Justice of the Supreme Court, the competent John Roberts, who will tolerate none of the misbehavior the Democrats repeatedly engaged in as this mess moved through the House.

Pelosi couldn’t stand to lose her spotlight, and, in one last shameful act, had a “signing ceremony” where she and other Democrats smiled and laughed as she pronounced President Trump “impeached forever” and handed out pens. Even some of her adoring fans in the liberal media said she went too far.

What now? The Senate will meet every day except for Sundays beginning at 1:00 p.m. Every senator must attend. They cannot talk or bring electronic devices. They will initially hear the House managers’ “case” for the articles of impeachment, and then the president’s lawyers will finally be allowed to present his case. Be prepared for the House managers to be longwinded and ineffective. Be prepared for the president’s team to be briefer and speak clearly to the essential points of weakness in the articles. Then senators will be allowed to ask questions through Chief Justice Roberts.

What happens next is unclear. Will the Senate dismiss the articles? Will they acquit the president? Will they unnecessarily delay things further by calling witnesses? We don’t know.

But, we do know that not a single Republican voted for these articles in the House and even a few Democrats voted against them. One Democrat changed parties over the vote. We also know there are not nearly enough senators to meet the two-thirds threshold to remove President Trump from office. And we know this will have all been a complete waste of time.

This fall, in the general election, the American people will finally have their say, as the framers of our Constitution intended. I predict Pelosi, Schiff and Nadler won’t be smiling.

Watch: Jessica Taylor touts ‘humble roots’, takes aim at ‘The Squad’ in first TV ad

Jessica Taylor, an attorney in Prattville seeking the Republican nomination for Alabama’s second congressional district, released her first television advertisement on Tuesday.

The ad, which is titled “My Squad,” is mostly composed of footage and soundbites from Taylor’s viral announcement video that garnered national attention.

The video begins by touting Taylor’s “humble roots,” and the candidate goes on to say she wants “to protect life, the Second Amendment, our borders and President Trump from socialists in the swamp”

203

Taylor’s competitors in the March 3 Republican Primary will be former Alabama Attorney General Troy King, former State Representative Barry Moore (R-Enterprise) and Dothan businessman Jeff Coleman.

According to Taylor’s campaign, the spot “will air on broadcast and cable over the next two weeks in the Montgomery media market beginning this Wednesday.”

Predictably in an ad titled “My Squad,” the spot makes references to “The Squad” while displaying images of Reps. Alexandria Ocasio-Cortez (D-NY) and Ilhan Omar (D-MN).

The Squad” is a group of four U.S. Representatives that are new to Congress, female and represent the furthest left wing of the Democratic Party. Cortez and Omar are two members of “The Squad” that have generated particular ire among Republican primary voters.

As a response to “The Squad,” Taylor led the effort to create the “Conservative squad,” which is composed of four female conservative Republicans currently seeking election to the House.

In a statement sent to reporters that accompanied the ad, Taylor said one of her goals in Congress would be to “fight back against radical socialists like AOC and Ilhan Omar.”

The spot also continues to use the language and iconography of basketball, which Taylor grew up playing.

“Alabama, put me in the game!” proclaims Taylor to conclude.

Bama’s Jared Mayden glad to be reunited with ‘natural leader’ Jalen Hurts for Senior Bowl

MOBILE — Reunited and it feels so good. That was the sentiment expressed by one of Jalen Hurts’ former University of Alabama Crimson Tide teammates during the Senior Bowl Week Media Day on Tuesday.

Hurts, of course, played for the Oklahoma Sooners this past season as a graduate transfer from Alabama. He finished as the runner-up in the 2019 Heisman Trophy voting.

He will play for the South Team during Saturday’s Senior Bowl at Ladd-Peebles Stadium, as will the Tide’s Jared Mayden, Terrell Lewis, Raekwon Davis and Anfernee Jennings.

As captured by Yellowhammer News, Mayden spoke with reporters during Media Day about how it feels being on the same field — and the same team — as Hurts once again.

173

“It means a lot,” Mayden stressed. “Especially since he’s on my team [as opposed to playing against him on the North Team]. I’m glad he’s on my team because Jalen’s a leader, a natural leader. He doesn’t have to try too hard. It just seems like it comes natural to him. I know he’ll probably have some things to say that’ll get everybody ready to play. He did it at Bama; I expect no less from him [now]. So I’m excited to get the opportunity to play with him again.”
