A new autonomous underwater vehicle (AUV) has been unveiled at the University of Tasmania’s Australian Maritime College (AMC) in Launceston.The AUV is capable of diving up to 5,000 meters, operating underneath the ice and gathering data on the Antarctic research missions.During an official ceremony, the $5 million polar vehicle was granted the name nupiri muka, which means ‘Eye of the Sea’ in palawa kani, the language of Tasmanian Aborigines.nupiri muka is funded by the Australian Government through the Antarctic Gateway Partnership — a $24 million special research initiative of the Australian Research Council (ARC) that aims to provide new insights into the role of Antarctica and the Southern Ocean in the global climate system. AMC contributed $3 million to the cost of the vehicle.The vehicle will be maintained and operated by a team of specialist research and technical staff at AMC’s Autonomous Maritime Systems Laboratory, a new engineering research facility.The AUV is a vital research tool that will be deployed in the Antarctic by Australian and international researchers, including from the ARC Antarctic Gateway partners the University of Tasmania, CSIRO and the Australian Antarctic Division (AAD).“This is an ambitious project that has built a world-leading, polar underwater vehicle equipped with new combinations of technologies to answer high priority science questions,” Antarctic Gateway Partnership director, professor Richard Coleman said.“The development process has built strong technical collaboration between AMC and the AUV manufacturer, International Submarine Engineering (ISE) of Canada. Proven concepts of underwater vehicle design and instrumentation were used, together with innovation in the integration of the operating systems and instrumentation.”Australian Maritime College principal professor Neil Bose said: “nupiri muka is the newest and one of the most capable AUVs in the world for use under sea ice and ice shelves. It will allow us to further build our global reputation for engineering in extreme environments, and help foster strong ties with the international research community.” “Alongside our other vehicles and thanks to our strong engineering and research team, we are well placed to undertake a range of academic, national interest and industry-partnered projects.”AMC AUV facility coordinator Peter King said the features of the polar underwater robot made it ideal for deployment in challenging, under-ice conditions.“At nearly seven meters long and weighing one-and-a-half tonnes, nupiri muka’s endurance enables it to travel more than 140 km or 24 hours without needing to be recharged. It’s also highly customizable, such that the engineering team can install a range of instruments in addition to those already on board,” King said.“nupiri muka completed its first set of trials in Tasmania this past July. The vehicle performed according to plan, completing several successful dives in the North Tamar. Subsequent longer and deeper trials are planned for coastal Tasmania over the next few months, with the goal of an Antarctic deployment in 2018-19.”Photo: University of Tasmania
WEST DES MOINES — Iowans who get a hankering for a midnight snack will soon have to head for a convenience store and not the nearest HyVee.Starting next Monday, the West Des Moines-based grocery chain will stop keeping its stores open around the clock. Hy-Vee spokeswoman Tina Potthoff says few customers do their shopping between midnight and 6 a.m., so all current 24-hour stores will be scaling back their hours.“We’re encouraging customers to check with their local Hy-Vee stores to get the exact times for their specific locations,” Potthoff says. “We have always had stores that were not 24 hours so this is just moving the rest of our stores to that scheduling model.”Some stores will close from 11 p.m. to 6 a.m., for others, it may be midnight to 5 a.m. Despite the downsizing of store hours, Potthoff says there will be no downsizing of staff. “We’ve been receiving some questions about whether or not people will be losing their jobs during this transition,” Potthoff says. “That is not the case. Everyone who works overnight hours, even though we’ll still need staffing overnight, those individuals that would typically be working or serving customers overnight will be moved to a busier shift during the day.”The chain has about 83,000 employees and is Iowa’s largest grocer. Potthoff says plenty of other types of businesses are dumping ’round-the-clock hours. “The trend is — really, we’re seeing many retailers not go 24-7,” Potthoff says. “There are others that are out there that are moving to more of the early morning to midday to nighttime feel for their customers and aren’t necessarily keeping their doors open for all hours of the day.”Hy-Vee has 265 stores. About half of them are in Iowa. The rest are in seven other Midwestern states.
