WHOI: Alvin Submersible Makes 5000th Dive in Gulf of California

first_imgWoods Hole Oceanographic Institution (WHOI)-operated human-occupied research submersible, Alvin, has made it’s 5000th dive at the end of November 2018.Alvin made its 5,000th dive during an expedition to the Guaymas Basin in the Gulf of California.The Navy-owned sub has been through a series of upgrades and advances that have completely re-made the vehicle and vastly expanded its capabilities.“Alvin revolutionized our understanding of the extremes that life can tolerate and caused us to re-think the origin of life on our planet,” said Adam Soule, chief scientist for the National Deep Submergence Facility (NDSF), which operates the sub. “The sub also continues to expand our knowledge of where and how life might exist on other planets.” Alvin, which is supported by funding from the National Science Foundation, executes about 100 dives per year, and over its life has accounted for more than half of all of the scientific dives carried out by human-occupied submersibles worldwide, WHOI noted.Currently, Alvin reaches a depth of 4,500 meters, and soon the sub will complete the final phase of its current upgrade, which will enable it to dive to 6,500 meters, putting 98 percent of the seafloor within its reach.“Alvin helped inspire the development of new generations of deep-submergence technology and vehicles,” said Andy Bowen, director of the National Deep Submergence Facility at WHOI. “And it continues to inspire generations of future scientists, engineers, and explorers.”last_img read more

Higginbotham and Smith return, Salakaia-Loto switches to six

first_imgThe pair will return on the bench, with Queensland also making two changes to their starting XV.Harry Hockings will start at lock, with Lukhan Salakaia-Loto shifting to flanker, while Angus Scott-Young will start at No.8 with Caleb Timu on the bench.Izack Rodda will also play, determined to help the Reds try and arrest the Crusaders record 17-game winning streak despite the death of his father last week.With each Super Rugby team having to rest its Wallabies at times in the lead-up to the World Cup, there had been some thought Rodda would take time off this week.But as he was last week, Rodda was determined to play and the Reds have respected his wishes. Queensland’s backline remains unchanged after causing headaches for the Highlanders in Dunedin.Coach Brad Thorn said it was good to have Higginbotham and Smith return.”They bring good experience and provide us with a strong bench,” he said.”Harry (Hockings) has been working hard at training and deserves his spot in the starting side this week.”Attack coach Jim McKay said thought had been given to starting Higginbotham and Smith, given their experience, but the starters had deserved to retain their places after the effort against the Highlanders.”There were discussions surrounding that but the other guys have done very well and on the back of last week where we played quite well — obviously we didn’t get the result we wanted to — we needed to recognise and reward that effort,” McKay said.”We’re confident in (the starters) but equally, we’re confident in the guys coming off the bench and doing a job for us as well.”last_img read more
