Exploring the warship Mars, the pride of Sweden's 16th-century navy (2014)

  What sort of wood was it made out of that those random shattered planks were heavy enough to sink? Also, I'm curious how they got such a bright, colorful wide-angle photo under 250 feet of water. Special camera? Ginormous lights? I think there's places where the water is really just that clear, but if this was one of those, surely it wouldn't have taken so long to find...

    There is a lot of wood that doesn't float, I guess the options were to put dense wood and less ballast or wood that floats and more ballast. I think it's oak and is just saturated with water though. Here is the "global wood density database" (an excel file): http://datadryad.org/repo/handle/10255/dryad.235 http://datadryad.org/repo/handle/10255/dryad.235 (http://datadryad.org/bitstream/handle/10255/dryad.235/GlobalWoodDensityDatabase.xls?sequence=1 http://datadryad.org/bitstream/handle/10255/dryad.235/Global...) http://blog.mischel.com/2012/10/21/woods-that-sink/ http://blog.mischel.com/2012/10/21/woods-that-sink/ The photograph is likely heavily photoshopped, the caption says it's a "composite photograph".

    The title of the photo says "composite photograph", perhaps several close up photos were stitched together?
