IamA underwater archaeologist. Want to learn about underwater exploration, shipwrecks, pirates, and sunken cities? AMA!
Hey Reddit, I'm underwater archaeologist Peter Campbell and with me is the staff of the free online course Shipwrecks and Submerged Worlds (https://www.futurelearn.com/courses/shipwrecks). We're here to answer any questions you have about underwater exploration: shipwrecks, sunken cities, underwater caves, and the best technique for fighting a giant octopus, let's hear what you've got!
EDIT: Thanks folks! This was so much fun. Its after midnight here in the UK so that is a wrap for today. Here's a picture of me exhausted: http://i.imgur.com/BvitNsz.jpg
If you have questions in the future, I'm always on Reddit and Twitter (@peterbcampbell). There are lots of good questions left, so I'll try to answer them tomorrow.
Check out the online course if you found this interesting. Its totally free and you can do it at your own pace. Skim things you aren't interested in and you are under no obligation to complete it (though please try!). There is some great info on shipwrecks, sunken worlds, pirates, naval warfare, and everything else you can imagine relating to underwater research.
EDIT: Back for day two! I'm trying to hit the questions I didn't have time for yesterday, but if you've got new questions then get them in now!
FINAL EDIT: Thanks folks, thats a wrap! You know where to find me on Reddit or the net if you have more questions. Also, check out this Discovery article on all the things left to find in the world! The greatest discoveries are just around the corner! http://news.discovery.com/history/archaeology/more-archaeological-finds-coming-through-tech-141004.htm
There appears to be enough interest that I'll set up a future AMA with a live feed from the research vessel, so you can see what life on board is like and what the robots are finding underwater!
