First up was the deployment of the Washington Offshore Surface Mooring.\u00a0 Its buoy, too, is a behemoth, weighing more than 8,000 pounds and 20 feet high. It is designed to remain in place collecting data in 542 meters of water. This deployment went smoothly off the port side of the ship.\u00a0 After this deployment, the deck seemed noticeably clearer for the two largest buoys were now in the water.<\/p>\n

With extra working room available on the deck, the team went about strategically locating the components that comprise the next deployment — \u00a0the Washington Offshore Profiler Mooring. This profiler mooring is smaller and of a different design than the Washington Offshore Surface Mooring. The profiler mooring has seven components, which are connected by stretch hoses that enable the mooring to survive rough winter seas.\u00a0 The profiler mooring also contains a Wire-Following Profiler that houses instruments. \u00a0The Wire-Following Profiler rolls up and down a taut wire rope 4 times a day, continuously sampling ocean characteristics from 25 meters below sea surface to 30 m above the bottom. (See illustration of its components).<\/p>\n

Here are the first components of the Washington Offshore Profiler Mooring to go into the water. The blue painted buoy is a submersible surface buoy. The orange ball is a sub-surface flotation device that keeps the riser taut. The two are connected by stretch hose, which allows the buoy to bob while the orange ball stays relatively fixed.<\/p><\/div>\n

This 7000-pound anchor was the last piece of the profiler mooring assembly to go into the water. Once it landed on the ocean bottom, it will hold the profiler mooring in place for the next six months until this mooring is recovered and a new one deployed.<\/p><\/div>\n

The team rounded out the day with another CTD cast and moving equipment into place on the deck to be ready for tomorrow\u2019s final mooring deployment.\u00a0 After that occurs, the deck will be empty until the first recovery scheduled for tomorrow (Saturday) afternoon.<\/p>\n

Today, Friday September 23, was another day of deployment on the Endurance\u2019s Washington Line.\u00a0 The Endurance Team reported on deck at 645 to begin preparing the deck for the movement of the mooring pieces into place for their ultimate deployment. By 8 am, the deck was ready.\u00a0 Deck cleats had been secured, tag lines to…<\/p>\n","protected":false},"author":145,"featured_media":533442,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[104],"tags":[102,101,171],"_links":{"self":[{"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/posts\/533439"}],"collection":[{"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/users\/145"}],"replies":[{"embeddable":true,"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/comments?post=533439"}],"version-history":[{"count":3,"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/posts\/533439\/revisions"}],"predecessor-version":[{"id":533449,"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/posts\/533439\/revisions\/533449"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/media\/533442"}],"wp:attachment":[{"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/media?parent=533439"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/categories?post=533439"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www2.whoi.edu\/site\/ooi-expedition\/wp-json\/wp\/v2\/tags?post=533439"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
