Legacy and Emerging Persistent Organic Pollutants in Antarctic Benthic Invertebrates near Rothera Point, Western Antarctic Peninsula

first_imgThe levels of pollutants in polar regions is gaining progressively more attention from the science community. This is especially so for pollutants that persist in the environment and can reach polar latitudes via a wide range of routes, such as persistent organic pollutants (POPs). In this study samples of Antarctic marine benthic organisms were analysed for legacy and emerging POPs to comprehensively assess the current POPs concentrations in Antarctic benthos and infer the potential sources of the pollutants. Specimens of 5 different benthic invertebrate species were collected in 2 distinct locations near the Rothera Research station (67°35’8″S and 68°7’59″W). Any impact of the nearby Rothera Station as a local source of pollution appeared to be negligible. The most abundant chemicals detected were HCB and BDE-209, reaching the highest concentrations in limpets and urchins, followed by sea stars, ascidians and sea cucumbers. The relative congener patterns of PCBs and PBDEs were almost the same in all species. Some chemicals (e.g. Heptachlor, Oxychlordane and Mirex) were detected in the Antarctic invertebrates for the first time. Statistical methods revealed that the distribution of the POPs is not only driven by the feeding traits of the species, but also by the physico-chemical properties of the individual compounds. Benthic invertebrates are excellent indicators of the contaminant patterns of inshore Antarctic ecosystems.last_img read more

Circumpolar projections of Antarctic krill growth potential

first_imgAntarctic krill is a key species of important Southern Ocean food webs, yet how changes in ocean temperature and primary production may impact their habitat quality remains poorly understood. We provide a circumpolar assessment of the robustness of krill growth habitat to climate change by coupling an empirical krill growth model with projections from a weighted subset of IPCC Earth system models. We find that 85% of the study area experienced only a moderate change in relative gross growth potential (± 20%) by 2100. However, a temporal shift in seasonal timings of habitat quality may cause disjunctions between krill’s biological timings and the future environment. Regions likely to experience habitat quality decline or retreat are concentrated near the northern limits of krill distribution and in the Amundsen–Bellingshausen seas region during autumn, meaning habitat will likely shift to higher latitudes in these areas.last_img read more

Quiet night Arctic ionospheric D region characteristics

first_imgVLF radio propagation recordings are used to determine the characteristics of the nighttime polar lower D region of the ionosphere. Recordings of both VLF phase and amplitude in the Arctic on days within ∼1‐2 weeks of the equinoxes enable their day‐to‐night changes to be determined. These changes are then combined with previously measured daytime polar D region characteristics to find the nighttime characteristics. The previously determined daytime characteristics were measured in the Arctic summer; the NRLMSISE atmosphere model is used to help determine the height change from daytime summer to daytime equinox (∼5 km lower). The principal path used was from the 16.4 kHz Norwegian transmitter JXN (67°N, 14°E) 1334 km northwards across the Arctic Ocean to Ny‐Ålesund (79°N, 12°E), Svalbard. Also used were the 2014‐km path from NRK (37.5 kHz, Grindavik, 64°N, Iceland) to Ny‐Ålesund, the 1655‐km path from JXN to Reykjavik (64°N, Iceland) and the 5302‐km path from JXN across the Arctic Ocean to Fairbanks (65°N) in Alaska. The night values of (the Wait parameters) H’ and β were found to average from ∼79 km at equinox down to 77 km near winter solstice (lower than the 85 km at low and mid‐latitudes by ∼7 km) and 0.6 km‐1 respectively. This lower height and its variability are shown to be consistent with the principal source of ionization being energetic electron precipitation.last_img read more

Arizona rides early lead to 6-1 victory over BYU

first_img Written by FacebookTwitterLinkedInEmailTUCSON, Arizona (April 17, 2018)—Arizona jumped out to an early lead and rode the arm of Juan Aguilera en route to a 6-1 defeat of BYU baseball on Tuesday night.Aguilera (5-0) twirled a one-hitter through six innings before surrendering his second hit of the evening as the Wildcats improved their record to 23-12.A ground-rule double prevented Arizona from getting a second run as it took a 1-0 lead into the second inning.Cougar starter Jordan Wood gathered momentum in the second frame with a pair of strikeouts and catcher David Clawson pegged the inning-ending out on a delayed steal to second. That momentum was short-lived as Arizona built a 6-0 lead through three-plus innings.The Cougar offense sputtered. Aguilera beaned Mitch McIntyre to start the third, but the Cougar freshman tried to steal second to no avail. A double play erased Brennon Anderson’s leadoff single in the fourth.Reliever Rhett Parkinson got out of a jam with Wildcats on second and third, fanning his third Arizona batter in as many innings to end the sixth frame.When McIntyre got a one-out single and Jarrett Perns drew a base on balls in the eighth from the Wildcats’ first reliever, it set the table for Anderson’s second single of the night. That single to left field plated McIntyre.The Cougars, now 18-16, take a break for final exams before hosting Utah on Tuesday.​ April 18, 2018 /Sports News – Local Arizona rides early lead to 6-1 victory over BYU Tags: Baseball/BYU Cougars Robert Lovelllast_img read more

Boston Red Sox visit the White House; some team members opt out in protest

first_img FacebookTwitterLinkedInEmaildkfielding/iStock(WASHINGTON) — The Boston Red Sox visited the White House Thursday afternoon to celebrate their October World Series win with President Donald Trump – an event a number of minority team members skipped in opposition to administration policies.Several key members of the team have opted out of the White House visit, including Red Sox manager and three-time World Series champion Alex Cora. Cora told Puerto Rican newspaper El Nueva Dia he “doesn’t feel comfortable celebrating in the White House,” because of the Trump administration’s disaster relief response to Hurricane Maria.Trump touched on disaster relief during a rally with supporters in Florida Wednesday night. While announcing $448 million in new disaster relief for areas of the Florida panhandle still recovering from Hurricane Michael, the president claimed that Puerto Rico received $91 billion to recover from Hurricane Maria.According to fact checks from the Associated Press and the Washington Post, only $11 billion has been distributed to Puerto Rico so far. The president’s number included the total $41 billion Congress announced and $50 billion in expected future aid.On Monday, Zineb Curran, the vice president of corporate communications for the Red Sox, told ABC News that the team supports and respects Cora’s decision.”We are grateful to our ownership for creating a culture where we discuss these issues openly and encourage individual decision making,” he said.Trump has recently disinvited other championship-winning teams from visiting the White House when their players were critical of him, including the Golden State Warriors and the Philadelphia Eagles in 2018.“Each Red Sox player is a shining example of excellence living out an American sporting tradition that goes back many generations,” Trump said at the event after recounting the Red Sox’s road to a World Series victory. “From the open fields of our rich farmlands to the playgrounds and the vacant lots of our great cities, kids everywhere learned to catch fly balls, swing for the fences and race for the plate. Baseball is truly America’s pastime.”Copyright © 2019, ABC Radio. All rights reserved.

NCAA alters ‘Rich Paul rule’ following criticism

first_img Beau Lund FacebookTwitterLinkedInEmailfilipfoto/iStock(NEW YORK) — Days after introducing controversial certifications requirements for agents to represent college basketball players considering whether to enter the NBA Draft, the NCAA has changed those qualifications, no longer requiring those agents to have a bachelor’s degree.Agents seeking to represent those athletes will now have to be in good standing with the National Basketball Players Association.“We are committed to providing student-athletes who are deciding whether to stay in school or explore NBA draft options with access to a wide array of resources to make their decision,” said the NCAA in a statement.The statement said the original requirements were meant to fulfill that goal, but that because “several current agents who have appropriately represented former student-athletes in their professional quest and whom the National Basketball Players Association has granted waivers of its bachelor’s degree requirement.”The original rules were criticized by many, largely because a number of current NBA agents did not attend college. Rich Paul, who represents NBA stars like LeBron James, Chris Paul, Ben Simmons and Anthony Davis, does not have a college degree. James and Paul were vocal in their criticism of the degree requirement for agents.Other requirements for agents to represent college athletes considering their draft options include certification by the NBPA for three years, payment of required fees, and an in-person NCAA qualification exam.Copyright © 2019, ABC Radio.
