from the coast guard at a briefing set for 3:00 eastern time. meanwhile, we are learning that canada is stepping up its rescue efforts sending in a ship, the hmcs glace bay, equipped with a hyperbaric recompression, and we will be joined in just moments. sandra: molly line outside the u.s. headquarters in boston. first get to mike tobin, live at the staging area for the search in st. john s, canada. mike, exactly what we know, officials are reporting the remote operated robot discovered this debris field near the titanic and they are saying it could be linked to the missing titan but cannot confirm that to be the case. what else are we learning? well, we have learned that certainly very discouraging news for the people who are holding out hope for a miracle in this case. i spoke with larry david who is larry daily, i should say, logistics specialist for titanic expeditions, he was down to the wreckage in 2003, and 1 of the things he points out is when you go down to the
and then metallic sounds. this was under the underwater telephone. somebody on thresher thought it might be useful to notify the surface ship that they were having trouble. so i am very intrigued, and there must be some record what the last communication was between the mother ship and titan. sandra: coming off yesterday when there was a glimmer of hope when the sounds were reported and that was thought to maybe, and by some chance be the crew on board trying to alert where they were. now reports of this debris field. if in the case, brad, they are not able to determine that that debris is from titan, do you believe they are going to continue this search based on the timeline of the oxygen running out, that the coast guard initially worked off of? that s probably one of the most painful questions for somebody, thankfully not for me, to make that determination. when do you decide to reclassify

your pre dive checkouts with the electronics, making sure your life support system is all loaded on board for the 96 hours that you want to have as a back up. it is many things. depending on what your mission is. scientific mission is all equipment working, the instruments and the senses. have you briefed your guests, if you will? because you usually have one pilot, sometimes you have a co pilot with things technical. but everyone else is pretty new to this, so you have to make sure they understand what to do in case of emergency. what buttons or what things to say on the underwater telephone. it is a carefully choreographed - underwater telephone. it is a i carefully choreographed ritual. what you think may have happened in this situation? well, since they have lost all communication, i think i read that somewhere in one of the reports, that would suggest that they had a problem while
