Polar marine ecosystems: major threats and future change

first_imgThis review of polar marine ecosystems covers both the Arctic and Antarctic, identifying the major threats and, where possible, predicting their possible state(s) in 2025. Although the two polar regions are similar in their extreme photoperiod, low temperatures, and in being heavily influenced by snow and ice, in almost all other respects they are very different. The Arctic Ocean is a basin surrounded by continental landmasses, close to, and influenced by, large populations and industrial activities. In contrast, the Southern Ocean is contiguous with all the other great oceans and surrounds a single land mass; Antarctica is remote from major centres of population and sources of pollution. Marine environments in both polar regions have been highly disturbed by fishing activity, but, in terms of pollution, some areas remain among the most pristine in the world. There are, however, both local and global pressures. Over the 2025 time horizon, the greatest concern for the Arctic is probably the ecological implications of climate change, particularly insofar as sea ice extent and duration are likely to be affected. Such changes are not expected to be as pronounced in the Southern Ocean over this time period, and concerns are related more to direct threats from harvesting of marine living resources, and the ability to manage these fisheries sustainably. In both polar regions, the capacity of marine ecosystems to withstand the cumulative impact of a number of pressures, including climate change, pollution and overexploitation, acting synergistically is of greatest concern.last_img read more

Outdoor Updates: A 14-year-old oil leak in the Gulf of Mexico has been contained

first_imgGovernment officials have installed a new underwater system for capturing oil 11 miles off of the coast of Louisiana where a leak has caused crude oil to spill into the ocean for the last 14 years. Taylor Energy Co. owns the site and is responsible for ending the leak, caused when one of its oil platforms fell during a hurricane in 2004. An estimated 10,500 to 29,400 gallons of oil is leaking from the site daily. The Coast Guard has been monitoring efforts to clean up the site and recently reported that the new system is meeting federal containment standards, noting that the once large sheen of oil on the surface of the ocean is now “barely visible.” A 14-year-old oil leak in the Gulf of Mexico has been containedlast_img

GSA boys’ basketball team falls to Orono in Class C quarterfinal

PHOTO BY HUGH BOWDENBANGOR — The George Stevens Academy Eagles dug themselves into a hole in the early going of Wednesday’s Eastern Maine Class C basketball quarterfinal against the Orono Red Riots. That hole proved to be so deep the second-seeded Eagles never could quite climb out as they were upset 68-57 by the seventh-seeded Red Riots, ending their season with a 15-4 record.GSA led just once in the game — when senior guard Kelsey Allen put his own rebound back up and in to score the first two points of the game at the Cross Insurance Center.Orono quickly went on a 11-2 run, five of those points coming from sophomore forward Jake Koffman as the Red Riots forged a lead they never relinquished.The Eagles, who struggled with their shooting throughout the first period, put together their only sustained run of the game in the second period, after the Red Riots had opened up a 23-8 lead.This is placeholder textThis is placeholder textSenior center Finn Davis-Batt got things started for GSA with a foul line jumper and junior center Nick Szwez hit two foul shots. Guard Taylor Schildroth followed with back-to-back baskets, sophomore guard Jarrod Chase and Davis-Batt then each knocked down a pair of free throws and Davis-Batt connected on another foul line jumper, leaving the Eagles trailing by a single point, 23-22.But that was a close as they would get.The Red Riots pushed the lead back up to six points on a pull-up jumper by Nick Desisto and a three-pointer by Tom Lucy before Schildroth hit a pair of free throws with no time on the clock to leave the Eagles trailing 28-24 at halftime.In the third period, GSA closed the gap to three points on a drive to the basket by Allen, but the quarter ended with the Red Riots in front 46-37.And in basketball, when a team is trailing with time running down, there’s little choice but to foul the opponent to stop the clock and hope that the ensuing free throws are off the mark.That wasn’t the case for Orono, and the Eagles could only watch as the Red Riots connected on 20 of 26 foul shots over the last eight minutes to seal the victory and advance to the semifinal round.Orono got balanced scoring with eight players contributing. Desisto and Jackson Coutts led the way with 15 points each, Damian Heeger followed with 11 and Kamron Hines chipped in with 10 as the Red Riots improved their record to 13-7.For the Eagles, Allen led the way with 21 points and Szwez and Schildroth finished with 10 points each.Click here for more photos of this game.

Women’s lacrosse starts conference play

first_imgFresh off a weekend trip to New York, USC women’s lacrosse now returns home to the sunny locale of Los Angeles to kick off their conference season this Tuesday.After battling long travel times, frigid weather and tough opponents, the Women of Troy split their weekend matchups in the Empire State, following up their 7-4 Saturday loss to No. 16 Stony Brook with an 11-7 Sunday victory over Marist College. Sunday’s win marked the first of the season for the team after dropping their opening game in heartbreaking overtime fashion to then-No. 5 Northwestern on Feb. 7 at the Coliseum. The Women of Troy enter conference play with a 1-2 overall record after losing the opening two games.“We learned from our loss Saturday and looked at Sunday as a new day with a new opportunity,” head coach Lindsey Munday said. “Now we need to learn from that Sunday game as well and continue to improve in preparation for Tuesday’s game.”USC faces a quick turnaround as they prepare for their third game in four days on Tuesday, as Fresno State comes to town to battle with the Women of Troy at McAlister Field. The Bulldogs enter the game with an 0-1 record after being kenneled by No. 19 Stanford in their season-opening 22-7 conference loss in Palo Alto last Wednesday, Feb. 18. The Tuesday matchup with USC marks the second game of four in a row on the road for the Bulldogs to start their 2015 campaign.Fresno State will be led by a duo of attackers in sophomore Caroline Dineen-Carlson and freshman Nicole Ortlieb.      Dineen-Carlson put home three goals in the Bulldogs’ game with Stanford, while Ortlieb added two of her own in her first collegiate game. Sophomore midfielder Kyleigh Westgarth will also be a handful for USC as an expert at draw-controls. Westgarth set a Fresno State single-season record last season as a freshman with 37 draw-controls and continued her success in their matchup with Cardinal, tallying five in a strong effort.“We have to be ready for Fresno (State),” Munday said. “They are a conference opponent, and especially coming off two far away games this weekend, much of our preparation will be mental, in addition to the obvious physical recovery that comes with playing games so close to one another.”Among others, the Women of Troy will be paced offensively by their own duo of attackers in junior Caroline de Lyra, who leads the team with 11 points on seven goals and four assists, and sophomore Michaela Michael, who has tallied 9 points on six goals and three assists. Michael also leads the team with 12 draw controls, followed closely by junior midfielder Amanda Johansen, who has 11.Defensively, the Women of Troy will be anchored by junior captain Courtney Tarleton and senior Elizabeth Eddy, who each have caused three turnovers so far this season. Defending the net for USC will be freshman goalkeeper Gussie Johns, who has made 10 saves and surrendered 26 goals in 54 shots faced.Tuesday’s matchup should be a good one, as the Women of Troy look to even their season record and start off conference play with a bang. Fans who come out to watch should expect a physical game, as the Bulldogs will be playing with chips on their shoulders after losing by    double-digit goals in each of the first two matchups these programs have met.“Conference games always add an element of intensity, so we need to be mentally and physically locked in,” Munday said. “However, we are excited for the conference season to begin and I think we are going to embrace that intensity fully.”The game kicks off Tuesday at 3 p.m. at McAlister Field.last_img read more
