Deep glacial troughs and stabilizing ridges unveiled beneath the margins of the Antarctic ice sheet

first_imgThe Antarctic ice sheet has been losing mass over past decades through the accelerated flow of its glaciers, conditioned by ocean temperature and bed topography. Glaciers retreating along retrograde slopes (that is, the bed elevation drops in the inland direction) are potentially unstable, while subglacial ridges slow down the glacial retreat. Despite major advances in the mapping of subglacial bed topography, significant sectors of Antarctica remain poorly resolved and critical spatial details are missing. Here we present a novel, high-resolution and physically based description of Antarctic bed topography using mass conservation. Our results reveal previously unknown basal features with major implications for glacier response to climate change. For example, glaciers flowing across the Transantarctic Mountains are protected by broad, stabilizing ridges. Conversely, in the marine basin of Wilkes Land, East Antarctica, we find retrograde slopes along Ninnis and Denman glaciers, with stabilizing slopes beneath Moscow University, Totten and Lambert glacier system, despite corrections in bed elevation of up to 1 km for the latter. This transformative description of bed topography redefines the high- and lower-risk sectors for rapid sea level rise from Antarctica; it will also significantly impact model projections of sea level rise from Antarctica in the coming centuries.last_img read more

Fugitive from Howard County on ATF’s ‘most wanted’ list arrested in Montana

first_imgELMA — A Howard County man classified as a “dangerous fugitive” by federal officials and wanted in Iowa on a weapons charge was arrested last week in Montana.The ATF says Elma, Iowa, was the last known address they had for 62-year-old Michael Duane Strain.U.S. Marshals arrested Strain at a remote ranch on Native American land in Montana. The Bureau of Alcohol, Tobacco and Firearms had listed Strain on their list of 15 “most wanted” fugitives. According to a news release, Strain has a criminal history that includes possession of explosive devices, trespassing and fleeing a peace officer.Officials say Strain is part of the “sovereign citizen” movement. The FBI describes the movement as “domestic terrorists” who say they “don’t have to answer to any government authority, including courts, taxing entities, motor vehicle departments, or law enforcement.”last_img read more

first_imgCLEAR LAKE — The Clear Lake girls held Garner-Hayfield-Ventura scoreless in the first quarter as the Lions went on to a 48-25 win in non-conference play last night in Clear Lake, as you heard on AM-1490/96.7-FM KRIB. Sara Faber and Kaitlyn VanderPloeg each had 13 to lead the Lions, who are now 17-2 on the season. The Clear Lake boys had all five starters score in double figures on their way to a 78-52 win over the Cardinals, as you also heard on KRIB. Jaylen DeVries had 16, Andrew Formanek 15, Jack Barragy 14, Carson Toebe 13 and Kody Kearns 12 for Clear Lake, as the Lions are now 16-2 overall. Clear Lake hosts Humboldt in North Central Conference play tonight starting at 6:15 on KRIB BOONE — New football districts were released on Thursday, but with the twist that these districts will only last one year, and that Class 4A will be reduced to 40 teams in a new regular season arrangement for the upcoming season. Seven groups will be organized for geography and with the intention of providing greater competitive balance to scheduling. The groups were organized by measuring a program’s last four years of football results through the IHSAA’s Ratings Percentage Index formula and their last four years of playoff success. No other classifications had this system applied to their redistricting process in this cycle. A recommendation to reduce the regular season to eight games and have 32 playoff qualifiers for Classes 3A down to 8-player made by the Iowa Football Coaches Association was denied by the board this week. With the reduction down to 40 teams in Class 4A, it means Mason City will drop to Class 3A after being the smallest school in 4A for the last two years:== 3A District 2 — Mason City, Ballard, Boone, Humboldt, Gilbert, Webster City== 2A District 3 — Clear Lake, Forest City, Hampton-Dumont-CAL, Iowa Falls-Alden, Roland-Story, West Marshall== 2A District 2 — Algona, Cherokee, Estherville, Garner-Hayfield-Ventura, Okoboji, Spirit Lake== 1A District 2 — Belmond-Klemme, Clarion-Goldfield-Dows, Eagle Grove, Pocahontas, South Central Calhoun, Southeast Valley== 1A District 4 — Central Springs, Waterloo Columbus, Denver, Jesup, Osage, Sumner-Fredericksburg== A District 2 — West Hancock, Alta-Aurelia, Bishop Garrigan, Manson Northwest Webster, North Union, St. Edmond== A District 3 — Newman, Lake Mills, Nashua-Plainfield, North Butler, St. Ansgar, West Fork== 8-Man District 2 — AGWSR, Clarksville, Janesville, Northwood-Kensett, North Iowa, Riceville, Rockford, Tripoli, Turkey Valley IOWA CITY — Monika Czinano scored 23 points and Kathleen Doyle, with a school assist record, and Amanda Ollinger had double-doubles  as No. 20 Iowa avenged an early Big Ten Conference loss with a 76-60 win over Nebraska.

Flags Guide Marine Home For Final Time

first_imgBy Gretchen C. Van Benthuysen |COLTS NECK – Holly Morgan was leaving the home of a friend she had been visiting on Raleigh Pass when she noticed people arriving with trays of food at the house next door.“I didn’t have a good feeling about that,” she thought at the time.As she later discovered, that house belonged to the Baldassare family, who had just lost their 20-year-old son and brother, Marine Cpl. Daniel Baldassare, a crew member on the KC-130 Marine aircraft that crashed in a rural Mississippi field on July 10, killing all 16 service members on board.Baldassare had attended Colts Neck High School with Morgan’s daughter, Samantha Turano, 22. Morgan would wave to him as he drove through the development of single-family homes and garden apartments in his small pick-up truck. It was dark green, she thinks.She knew his stepmother Kelley, but not his father Vincent nor his sister Felicia. She knew he joined the U.S. Marines during his high school senior year, a goal he’d had since middle school.“I wanted to embrace the family — their son was about the same age as my daughter,” she explained. “But I wanted to give them their space.”The next day Morgan noticed someone had planted small American flags around the Raleigh Pass cul-de-sac. That sparked an idea. Why not extend the flags out onto both sides of Colts Neck Boulevard which runs the length of the development, nearly a full mile?She Googled New Jersey flags makers and flag sellers, Veterans of Foreign Wars and American Legion posts, and U.S. Marine Corps Recruiting offices, hoping they could donate flags. She posted her plan on residential development’s website and the Facebook page.Crystal Kaplan of Exeter Pass, a volunteer who plans family social events for the community, spread the word. She had lost an uncle in a military helicopter accident and also wanted to be a good neighbor and citizen.Boxes of flags began arriving. Offers of flags began arriving. Morgan drove all over New Jersey to pick them up. Other residents of The Grande development took up the cause and dropped off flags at her apartment on Hancock Pass. She lost count of the number of flags she received.“Maybe 4,000?” she said when pressed. A friend stored the overflow at her home.Morgan also gathered about 30 volunteers and late Monday afternoon they began planting the flags at The Grande and at Colts Neck High School, where a memorial service was held Tuesday morning on the football field for Baldassare, a former member of the school’s team. Even when a thunderstorm moved in around 9:30 that night and chased away most of the volunteers, Morgan and her other daughter Terri, 10, who will be a fifth grader at the Conover Road Elementary School this fall, and a few others kept working.Maryse Markowitz of Exeter Pass was returning home Monday night from her job at the Freehold Raceway Mall, which closes at 9:30 p.m. When she turned into the development and saw all the flags, she said she choked up.“It was just so moving and it was so quiet,” she said. “I didn’t know the boy, but I have a 20-year-old daughter.“All these people wanted was to honor him,” she said. “I have a strong and powerful faith and these people proved there is goodness in this world.”Glenn Taglieri, also of Exeter Pass, echoed her sentiment.“Just when you give up on people, something like this happens that restores your faith,” he said, adding his daughter was a classmate of Baldassare. “He always wanted to be a Marine and he accomplished that goal in his short life. My wife said other people live long lives and never achieve their goals.”Morgan, who didn’t really want the attention her desire to do something for the Baldassare family has brought her, said there was a kind of selfish reason behind her effort.“I want my daughter Terri to be the kind of kid who goes the extra mile and to not expect anything in return for it,” she explained. “I want her to forget all this materialistic nonsense and dare to be like Danny. To live and be kind and be different … dare to do it.”This article was first published in the July 27 – Aug. 3, 2017 print edition of The Two River Times. This article was corrected online to reflect the correct spelling of Morgan.last_img read more
