Abundance and distributional patterns of benthic peracarid crustaceans from the Atlantic sector of the Southern Ocean and Weddell Sea

first_imgClimate change is influencing some environmental variables in the Southern Ocean (SO) and this will have an effect on the marine biodiversity. Peracarid crustaceans are one of the dominant and most species-rich groups of the SO benthos. To date, our knowledge on the influence of environmental variables in shaping abundance and species composition in the SO’s peracarid assemblages is limited, and with regard to ice coverage it is unknown. The aim of our study was to assess the influence of sea ice coverage, chlorophyll-a, and phytoplankton concentrations on abundance, distribution and assemblage structure of peracarids. In addition, the influence of other physical parameters on peracarid abundance was assessed, including depth, temperature, salinity, sediment type, current velocity, oxygen, iron, nitrate, silicate and phosphate. Peracarids were sampled with an epibenthic sledge (EBS) in different areas of the Atlantic sector of the SO and in the Weddell Sea. Sampling areas were characterized by different regimes of ice coverage (the ice free South Orkney Islands, the seasonally ice-covered Filchner Trough and the Eastern Antarctic Peninsula including the Prince Gustav Channel which was formerly covered by a perennial ice shelf). In total 64766 individuals of peracarids were collected and identified to order level including five orders: Amphipoda, Cumacea, Isopoda, Mysidacea, and Tanaidacea. Amphipoda was the most abundant taxon, representing 32% of the overall abundances, followed by Cumacea (31%), Isopoda (29%), Mysidacea (4%), and Tanaidacea (4%). The Filchner Trough had the highest abundance of peracarids, while the South Orkney Islands showed the lowest abundance compared to other areas. Ice coverage was the main environmental driver shaping the abundance pattern and assemblage structure of peracarids and the latter were positively correlated with ice coverage and chlorophyll-a concentration. We propose that the positive correlation between sea ice and peracarid abundances is likely due to phytoplankton blooms triggered by seasonal sea ice melting, which might increase the food availability for benthos. Variations in ice coverage extent and seasonality due to climate change would strongly influence the abundance and assemblage structure of benthic peracarids.last_img read more

Not all icequakes are created equal: basal icequakes suggest diverse bed deformation mechanisms at Rutford Ice Stream, West Antarctica

first_imgMicroseismicity, induced by the sliding of a glacier over its bed, can be used to characterize frictional properties of the ice‐bed interface, which are a key parameter controlling ice stream flow. We use naturally occurring seismicity to monitor spatiotemporally varying bed properties at Rutford Ice Stream, West Antarctica. We locate 230000 micro‐earthquakes with local magnitudes from –2.0 to –0.3 using 90 days of recordings from a 35‐station seismic network located ∼40 km upstream of the grounding line. Events exclusively occur near the ice‐bed interface and indicate predominantly flow‐parallel stick‐slip. They mostly lie within a region of interpreted stiff till and along the likely stiffer part of mega‐scale glacial landforms. Within these regions, micro‐earthquakes occur in spatially (<100 m radius) and temporally (mostly 1‐5 days activity) restricted event‐clusters (up to 4000 events), which exhibit an increase, followed by a decrease, in event magnitude with time. This may indicate event triggering once activity is initiated. Although ocean tides modulate the surface ice flow velocity, we observe little periodic variation in overall event frequency over time and conclude that water content, bed topography and stiffness are the major factors controlling microseismicity. Based on variable rupture mechanisms and spatiotemporal characteristics, we suggest the event‐clusters relate to three end‐member types of bed deformation: (1) continuous creation and seismogenic destruction of small‐scale bed‐roughness, (2) ploughed clasts and (3) flow‐oblique deformation during landform‐formation or along bedrock outcrops. This indicates that multiple processes, simultaneously active during glacial sliding, can accommodate stick‐slip behaviour and that the bed continuously reorganizes.last_img read more

Towards implementing artificial intelligence post-processing in weather and climate: Proposed actions from the Oxford 2019 workshop

first_imgThe most mature aspect of applying artificial intelligence (AI)/machine learning (ML) to problems in the atmospheric sciences is likely post-processing of model output. This article provides some history and current state of the science of post-processing with AI for weather and climate models. Deriving from the discussion at the 2019 Oxford workshop on Machine Learning for Weather and Climate, this paper also presents thoughts on medium-term goals to advance such use of AI, which include assuring that algorithms are trustworthy and interpretable, adherence to FAIR data practices to promote usability, and development of techniques that leverage our physical knowledge of the atmosphere. The coauthors propose several actionable items and have initiated one of those: a repository for datasets from various real weather and climate problems that can be addressed using AI. Five such datasets are presented and permanently archived, together with Jupyter notebooks to process them and assess the results in comparison with a baseline technique. The coauthors invite the readers to test their own algorithms in comparison with the baseline and to archive their results.last_img read more

‘I don’t believe in luck’: NASCAR champion Joey Logano gets real on racing

first_imgMay 26, 2019 /Sports News – National ‘I don’t believe in luck’: NASCAR champion Joey Logano gets real on racing Written by FacebookTwitterLinkedInEmailCourtesy Joey Logano(CONCORD, N.C.) — The first time reigning NASCAR champion Joey Logano got behind the wheel was when he was 6 years old. He tore up his Connecticut neighborhood in a go-kart, a Christmas present given to him by his parents.That go-kart changed his life.Logano, who drives the No. 22 Ford Mustang for Team Penske, stunned racing fans last November when he clinched the NASCAR Monster Energy cup series championship as the underdog, beating out rivals Kyle Busch, Kevin Harvick and Martin Truex Jr. at Homestead-Miami Speedway in Florida. Logano was the youngest driver to win in 15 years and his victory was the first cup series title for Ford Motor Co. in 14 years.Being a champion hasn’t changed the lithe, unassuming and affable Logano.“The goal last year was to win the championship,” he told ABC News at the Ford Performance Technical Center in Concord, North Carolina, before the All-Star Race. “The goal this year is to win the championship. The pressure you put on yourself really doesn’t change.”Logano, 29, latched on to NASCAR early, watching the races at a young age and convincing his parents to invest in his burgeoning hobby. Racing — not college — was his dream.“I sign my name Joey Logano RCD. Race Car Driver,” he said. “I feel like I have a degree in racing. No one really ever said, ‘Hey, you should have a backup plan.’ My plan was to be a professional race car driver. I was 15 years old when I got signed up [to drive] a race car for someone else. My eggs were all in one basket. I had to make it work.”Logano has won one race so far this season, securing a spot in the playoffs beginning in September. He said his sole focus is defending his NASCAR title. But Logano recognizes that every driver has a shelf life.“I don’t want to go out there and run 15th every week,” he said. “I am not going to have fun doing that. I love winning. I hate losing even more. I know at some point I am going to lose a little bit of that edge … and may have to work in different ways to keep that edge. We have seen drivers racing into their mid-40s and be very competitive. I still have a long ways to go in my career.”When asked if he would consider trying his luck in Formula One, the pinnacle of European motorsports, Logano was circumspect.“I would like to try it. I am not sure I would actually want to do that for a living,” he said. “I don’t want to say never. For me, I grew up loving NASCAR racing. My passion lies in stock cars. We’re not worried about ripping a wing off. We’re going to rub fenders and it’s going to be a lot of fun and we’re going to laugh about it or maybe throw punches afterward.”He would, however, jump at the opportunity to test his limits and stamina in the prestigious 24 Hours of Le Mans, one of the oldest automobile races in the world.“I would love to try that,” he said with a smile. “Hopefully someday that can happen.”These days Logano’s free time is limited, even in the off season. When he’s not with his wife Brittany and 16-month-old son Hudson or attending sponsor-related events, he can be found tinkering with his own cars: a Ford F-150 Raptor truck, 1924 Model T and Ford GT supercar.“I bought a Ford GT a couple of years ago,” he said. “That was a pretty big splurge but totally worth it. I’ve put some miles on it. VIN number is 22 [his racing number]. So it’s a real special car.”To NASCAR fans, the drivers are the celebrities. But in reality the sport is a team effort and hundreds of people can work on one driver’s car. If Logano performs poorly in a race, he shares the blame.“I make plenty of mistakes, believe me,” he said. “My car’s not always perfect either. We have 400 employees at Team Penske building race cars. There are so many people that go into this. I am just a piece of the puzzle.”Some drivers believe in good luck rituals before a race. Dale Earnhardt would reportedly enter and leave a building through the same door. Sterling Marlin ate a bologna sandwich. Others refuse to shave on race day. Not Logano.“I’m not superstitious at all,” he said. “I don’t believe in luck.”Men still heavily dominate NASCAR and this year’s roster is no exception. Superstar Danica Patrick, who retired from racing in 2018, helped inspire young girls to pursue motorsports. But more needs to be done to increase the number of female drivers, Logano argued.“I think it would be very healthy for the sport,” he said. “There are a few females coming up right now that have a good amount of talent.”As for that NASCAR trophy, Logano is finally looking forward to bringing it home.“The championship trophy is on tour. To be honest I don’t know who has it right now,” he said with a laugh. “We decided to give everyone on the race team the trophy for a week to take home. I know it’s going to get scratched up, things are going to happen, but it will have some cool stories, neat pictures and I wouldn’t have it without them.”Copyright © 2019, ABC Radio.

He reached the postseason 17 times (13 at Utah), including 12 NCAA Tournament appearances (11 at Utah). He won 10 conference titles in 13 years at Utah, and took the Runnin’ Utes to the Sweet 16 in 1991 and 1996, and the Elite Eight in 1997.“During his time here at Utah Coach Majerus was simply one of the best coaches if not the best coach in the country,” said Athletics Director Emeritus Dr. Chris Hill, who hired Majerus in 1989. “We are thrilled that he is receiving this tremendous honor. When you look back at the ‘Majerus Era’ it is so amazing what he and his teams accomplished.”Majerus’ most memorable season came in 1998, when he led Utah to 30 wins and an appearance in the national championship game. He earned five WAC Coach of the Year awards and was named the National Coach of the Year by Basketball Times in 1991.Majerus, who coached the Utes from 1989-2004, ranks third all-time in school history with 323 wins while roaming the sidelines at Utah. His .773 (323-95) overall winning percentage ranks first among coaches at Utah with at least 100 wins, and his .779 (152-43) conference winning percentage ranks first overall as well.

ZPG buys share in Dubai-based Propertyfinder portal

first_imgZPG has made a surprise investment in Dubai-based property portal owner Propertyfinder Group (PFG) for an undisclosed sum, giving it a door into the global property market in the Middle East and North Africa (MENA) region.PFG is a parent company of seven property websites across the region including the UAE, Qatar, Lebanon, Egypt, Morocco, Bahrain and Saudi Arabia.PFG was started up in 2005 by US businessman Michael Lahyani (pictured, left) and through both acquisition and growth was recently valued at $200 million following a $20m investment by a Bermuda-based but Russian company called Vostock.The deal, which was announced last year, was described by Lahyani at the time as enabling the company to become the biggest online real estate “destination” in the MENA region.But although Lahyani describes himself as the founder, PFG’s UAE website was originally 51%-owned by Australia’s REA Group before being sold off when the company pulled out of what had been early attempts at a global property portal empire. Lahyani started a magazine in Dubai called Al Bab World which was later bought by REA and then turned into the Propertyfinder.ae website.At the time during the mid-to-late noughties the REA network included sites in Italy, France, Belgium, Hong Kong – and in the UK. Nick Leeming’s Propertyfinder.co.uk was once a serious rival to Rightmove.Older agents will recognise PFG’s site logos and website design from when Propertyfinder was active in the UK, before ultimately being sold to ZPG in August 2009.PropertyfinderPFG says it is the market leader in five of the seven markets it is active within, and has 200 staff and total monthly visits of two million, a major improvement compared to eight years ago when it had just 44,000.As part of the original deal ZPG kept the www.propertyfinder.com address but this, as part of the investment revealed today, has been transferred to PFG most likely so it can harmonise its URLs across all seven countries. These are currently a hotch-potch of different address combinations.“Their business is growing fast and we have no doubt that we can add strategic value as a shareholder,” says Alex Chesterman, CEO of ZPG (pictured, right).Michael Lahyani says, “I have known Alex for years and we have always enjoyed strategic conversations on the real estate classified space.“Having ZPG as a shareholder is not only a vote of confidence in our business but also an opportunity to secure the propertyfinder.com domain name, a strategic asset for our group.” Michael Lahyani PFG Alex Chesterman propertyfinder ZPG June 6, 2017Nigel LewisWhat’s your opinion?
