Imaging technique removes the effect of water in underwater scenes | MIT News
The ocean is teeming with life. But unless you get up close, much of the marine world can easily remain unseen. That’s because water itself can act as an effective cloak: Light that shines through the ocean can bend,…

Using sound to ‘see’ unexploded munitions on the seafloor
More than 400 underwater sites in the United States are potentially contaminated with unexploded ordnance (UXO) — weapons that did not explode upon deployment, which continue to pose a safety concern.
Connor Hodges, a doctoral student at the…
