Continental-slope and shelf-edge morphology off Marguerite Bay, western Antarctic Peninsula, is investigated using swath-bathymetric data and parametric sub-bottom profiler records, together with sediment cores. Marguerite Bay has a well-defined cross-shelf trough, and a relatively steep continental slope. The slope beyond the trough mouth is convex in longitudinal profile, whereas to the north and south it is concave and reaches a maximum of 12degrees. There are no deep canyons cutting into the prograding outer shelf and slope. Instead, a series of gullies runs down the upper slope, reaching depths of >200 m south of the trough mouth but <120 m deep beyond the trough. The mid and lower slope appears to be relatively smooth and downslope sediment transfer is probably by small-scale slides, slumps and debris flows. The continental rise contains dendritic channels related to turbidity currents, and sediment drifts produced by southwest-flowing bottom currents from the fine-grained component of the turbidity currents. Elongate sedimentary bedforms indicate that a fast-flowing ice stream occupied the trough under full-glacial conditions, and transferred deforming subglacial till rapidly to the shelf edge. By contrast, on either side of the trough mouth, ice is inferred to have been slower-moving and probably cold-based, delivering little sediment to the upper slope. The steepness of the continental slope results in rapid downslope sediment transfer by debris flows, slumps and turbidity currents and accounts for the lack of a well-developed trough-mouth fan, which is typical of many lower-gradient glacier-influenced margins.
Categories: Letters to the Editor, Opinion“Sweeteners” help sell contract dealsHere’s a reaction to your editorial on sick day payouts, based on my experience in faculty negotiations.While these may seem extravagant viewed in isolation, such items often make sense from a broader perspective. Tweaking of such “sweeteners” such as deferred benefits can help bring about a deal in the case of an otherwise disappointing package. A little enriching here can make up for a much larger reduction in the big-ticket items, pay and major benefits. Likewise, the positives of sick day features such as incentive for fuller attendance, minimizing student disruption and reduced substitute cost can help management negotiators sell the full imperfect settlement to their masters.Paul BryantSchenectady Give e-car racing coverage it deservesI know Formula E is still a new form of car racing, but all electric cars are in our future and Formula E is here now.There were two races in Brooklyn, the final city race on July 13 and the championship race on July 14. A little coverage would help the sport grow. Nice you included results for Formula 1 and Indy car from foreign countries, but you missed another international racing sport right here in New York.As they say “there’s an app for that.” Check it out.

Yet, governments continue to mandate the burdens and costs of recycling, particularly wasting water to clean plastics, fearing once the habit is broken, consumers will not recycle should the practice become planet-friendly in the future.Could The Gazette please investigate what happens to our recycled papers and plastics in Schenectady County? I would like to know if all the energy used to clean and collect recyclables is being wasted.Jerry MooreScotiaTrump cheated his way out of militaryI’m responding to William Young’s July 13 letter (“Trump not alone in no military service”). Mr. Young correctly pointed out how many former presidents of the United States had not served in the military. Apparently, the list was designed to point out that President Trump was actually no different than any of those former presidents or Gov. Cuomo for that matter.Trump is a draft-dodger who used his wealth to get a doctor to falsify his medical records. No other president did that. That seems like a breathtaking difference to me, and I think it’s a huge difference to most people. I’m surprised that it doesn’t matter to Mr. Young.He wants us to stop whining about a draft-dodging president based on comparison to other presidents who simply didn’t serve. They aren’t any more the “same” than lightning and a lightning bug.You shouldn’t have to be struck by lightning to perceive the difference.Glenn GraySchenectadyMore from The Daily Gazette:EDITORIAL: Find a way to get family members into nursing homesGov.

With 23 minutes remaining in the first half, Syracuse goalkeeper Jordan Harris lined up to defend a Taylor Otto penalty kick. A goal would put No. 3 North Carolina up two goals, an advantage UNC hasn’t surrendered this season. Harris read Otto’s shot the entire way. She dove quickly to her left, pushed the ball away from the net and jumped up with an enthusiastic scream. She was immediately mobbed by defenders Taylor Bennett and Shannon Aviza. The crowd at SU Soccer Stadium erupted, and emotions were high. But that atmosphere would last for mere minutes. Less than two minutes later, UNC’s Brianna Pinto sent a corner kick sailing over all of the Orange defenders to a wide-open Julia Ashley. The senior headed the ball in the back of the net, granting the Tar Heels a two-goal lead. The Orange (3-11, 0-6 Atlantic Coast), winless in conference play, kept it close for 65 minutes against a Tar Heels team undefeated in conference. But SU fell apart during the final 25, allowing four goals during that span, en route to a 7-1 loss to UNC (10-2-1, 6-0-0) on Sunday afternoon. Seven different players scored goals for the Tar Heels, who outshot the Orange 29-5. The loss extended SU’s losing streak to nine. AdvertisementThis is placeholder textBlessing Emole | Digital Design Editor“I thought we had some good spells where we did keep (the ball),” SU forward Meghan Root said. “We just need to do it more consistently.” Bridgette Andrzejewski opened the scoring for North Carolina less than five minutes in. On a free kick, she positioned herself in front of SU’s Kate Hostage and headed a Pinto free kick into the right corner of the net. “It’s just about being physical-on set pieces,” head coach Phil Wheddon said. “We didn’t get a body on them, and … against a team of this caliber, you’re not going to get any breaks.” Root, a freshman forward, scored the Orange’s only goal late in the first half. She got behind Andrzejewski and took advantage of a misplay by Ashley, sending the ball into the back of the net, cutting the deficit to 2-1. The Tar Heels responded less than seven minutes later, with Alex Kimball squeezing the ball through Harris and defenders Clarke Brown and Aviza. That became the blow SU could not recover from the rest of the game. As the clocked ticked down to 10 seconds remaining in the first half, defender Clarke Brown cleared the ball out of bounds against the net. Preparing to defend a final UNC rush, Syracuse assistant coach Ben Boehner started shouting, “Everyone back, 20 seconds, go back!” The Orange forgot to account for Ashley, however, who snuck in behind defenders Molly Nethercott and Jenna Tivnan and headed a last-second shot off the left post. Harris looked with confusion towards her two teammates after the defensive breakdown with her palms raised upward. Wheddon and his staff stayed out on the field for more than three minutes during halftime, discussing the closing seconds of the half. “We lost to Louisville 1-0 with 9 seconds left on the clock, and they (UNC) had less than 20 seconds on the clock,” he said. “And again, we fell asleep for that moment, and it hit the post.” The halftime adjustments to set-piece defending worked for SU in the first part of the second half. But in the last 25 minutes, North Carolina scored four-straight goals, including its last three in six minutes and finishing with its highest goal total of the season. After the game, while the rest of the Orange were going through their post-game stretching routine, Wheddon pulled aside Harris, a redshirt senior, and talked to her privately. The keeper had 11 saves on the day, including the penalty kick stop that injected a glimmer of hope into the Orange. “I thought Jordan had a big performance,” Wheddon said. “She’s upset that she conceded the goals, she’s taken ownership for some of the goals that were possibly preventable.” Many of the goals scored by UNC weren’t avoidable, though. “UNC is a good team, they have…tons of national team players,” Root said, “so they’re going to be able to knock around the ball.” Published on October 7, 2018 at 6:12 pm Contact Andrew: [email protected] | @CraneAndrew Facebook Twitter Google+ Comments
