P-MAN XVI Update # 15 - Data analysis, murky water, and the Alien Finder

26 March 2014

Today was a water day for everyone except Dan O'Brien. He wanted a day back at the ready room to get caught up on photos, reports and all forms of stored digital files. And he ran some errands. And he secured another van for us for a few days. And maybe he caught a nap as well.

We got to Neco Marine around 0940, grabbed our SCUBA gear, loaded the boat and then we picked up Eric and Shannon from the Scripps/UDel group at the Coral Reef Research Foundation dock. That's about 100 yards from where our boat was parked.

Reviewing SSS data the previous night showed us we should look at some "interesting" targets.

I'll get to the point quickly. We saw a lot of dark brown coral outcroppings along a sandy/silty bottom. Very little manmade stuff found its way into the areas that we explored. So no clues to the next find.

Most of our dives were at about 70 feet. Except one that was down about 105 and the bottom was further down at 122. However, from the latitude/longitude we were given, it too was supposed to be about 75 feet. Hmmmmm? We'll have to revisit the correct spot later.
We did 3-4 dives each with Shannon and Eric taking turns utilizing the Alien Finder. Okay, it has a real name: Shark Marine Navigator built by a company called Blueview. It uses a high resolution imaging sonar that is integrated into a diver portable system. It allows us to search in low to no visibility settings underwater that would be impossible otherwise - sort of like pilots flying on instruments. It just looks like an Alien Finder. But whatever it is called, it really helps with searches.

We called it a day about 4 p.m.. Back to Neco, cleaned up our gear and met the folks from Cleared Ground Demining. Steve and Cassandra run a NGO that cleans up former battlefields of munitions (UXO). They've become great friends of The BentProp Project and it's always great to get caught up with them.

We did another night-time review session. We looked at the day's SSS results and have picked half a dozen targets in an area where we believe a Hellcat went in. On our next water day we'll prosecute these targets. We also reviewed some data that are being developed in hopes of creating a search plan for the last of the B-24s to be found. Our partnership with Scripps/UDel is rich in numerous ways.

Speaking of partnership, I'd like to talk about this a bit more. I went back into our updates from a few years ago. We reported about meeting the Scripps/UDel folks for the first time in P-MAN XIV Update #06 - Corsair!

[22 March 2012] - We stopped in at the Coral Reef Research Foundation (which is next-door to Neco) and found the REMUS teams. They are here, at least for the rest of the day, doing oceanographic work with their autonomous ROVs. These guys have some really cool toys. They also like what we do and sent their AUV over some of our side-scan sonar (SSS) hits. I think our Stockbridge ROV team is going to be really happy as all these areas are a target rich environment. They are GOING to image more than the swimming-pool drains that have comprised most of their testing so far. Most of the REMUS folks are leaving tonight, but a few are staying behind for a few more days to finish up and pack out. The Stockbridge ROV team will have a chance to visit with them on Saturday before they pack up their toys and go home.

Then a funny thing happened. We stayed in touch, showed Scripps/UDel more of what we do and they showed us what they do. Working with BentProp actually furthers their mission goals. The U.S. Office of Naval Research (ONR) is a major sponsor of the Scripps and UDel teams. ONR has made investments in developing new underwater and unmanned technologies for the Navy, and the Bent Prop mission serves as a real-world proving ground for testing and demonstrating these emerging capabilities. Dr. Terri Paluszkiewicz from ONR, who visited last year for part of the expedition, has been supporting Scripps/UDel for several years now. The partnership between ONR, Scripps/UDel and BentProp furthers the overall Naval mission by exposing the public to exciting science and engineering and provides inspiration to school kids like the group out of Stockbridge, Michigan.

STEM, Science, Technology, Engineering and Mathematics, is a big buzzword in education today. Looking down the road, it's one thing to just make use of an iPhone or any sort of technology for fun and profit. But it's quite another to have a firm understanding of how it works, how to design it, build it and how to think out of the box and make the next great discovery. BentProp helps Stockbridge further the education of their students by giving them the chance to design, build and deploy their underwater vehicles and then explore in the real world. This extends the partnership from ONR, directly through Scipps/UDel and BentProp to the Stockbridge High School students. And these young men and women are our future, whether in the military or whatever path they go through in life.

27 March

I was going to have a separate update for today, but we did not go out on a boat, or go out into the jungle. After five days of diving, we needed a down day. So everyone took an admin day. That doesn't mean we did not accomplish stuff. Dan, Joe, Sean and Casey took a helicopter ride looking at some metal found on the top of one of the islands. I worked on a modification to my BC. Pat gave a presentation to a medical clinic in town.

Derek went for a run. Everyone who's on Facebook checked in there (and consequently bandwidth got eaten up). We'll most likely have another SSS scrub with Scripps/UDel tonight.
