Turning Back towards Shore

Friday, November 21st, 2014

After roughly a day and a half at sea, Challenger reported back with one of the worst messages possible (second to no contact at all that is): an abort triggered by the leak detect.

Similar to the previous deployment in July out of Santos, RU29's leak detect mechanism was triggered at depth resulting in the glider returning back to the surface to report on the matter.  David Aragon then spent a significant amount of time running tests on the glider resulting in the decision to turn the glider back towards shore.

29 will now spend the weekend weaving her way back to the North West, where early next week a team will depart from the University of Sao Paulo, recover the glider, and report back to us on the gliders condition so we can than make further plans from there.  But we will have more on that next week as the events transpire.

On another note, the images from the deployment of RU29 and USP03 are now online! Below are a select few but the full set can be viewed on our flickr page

Ready Player One

Wednesday, November 19th, 2014

After months of sitting in pieces being worked on in labs ranging from the University of Sao Paulo to Teledyne Webb Research and Rutgers University, RU29 is back in the game.  David Aragon and Chip Haldeman spent roughly a week down in the USP facilities after gathering up all of her parts, where they then assembled Challenger and prepared her for her next mission- a feat that wouldn't have been possible without the help of our friends at both the university in Brazil and at TWR.

Early Monday morning (Nov 17, 2014), the boat departed Ubatuba around 5:30am (2:30am EST) and within a few hours the glider was deployed amongst the rolling swell of the sea, off of the Southern Brazil Bight.

Now following the line dubbed the Ilhabela Line (Native for Beautiful Island after the island near to the deployment team's departure point), Challenger will fly across the shelf before we eventually hit deep water and aim our sights on Cape Town.

There is also some great news from our friends at Teledyne Webb Research on the other Challenger Mission Glider, Silbo.  After drifting at the surface for roughly 72 days and being rescued by fisherman off the coast of Barbados in August of 2013, Silbo has undergone a lengthy refurbishment process during which amongst a number of other upgrades, he has received a new pump and thruster system.  Soon he will be deployed for an off shelf test out of Woods Hole, Massachusetts where the new rig will be tested thoroughly before we set forth on the next North Atlantic Mission: spanning from North America across the northern region of the ocean basin towards our partners in Ireland and the United Kingdom and eventually Svalbard, Norway.

Finally, we are moving to a new location!  In order to consolidate the information on the Challenger Glider Mission and ensure the most information possible is accessible to our readers, we have opened our new blog at http://challenger.marine.rutgers.edu/blog/
