ABOARD THE R/V THOMAS G. THOMPSON—In the early morning hours of Saturday, May 10, we were on the seafloor in the deepest part of the Kermadec Trench when all of the video screens in the Nereus control room went dark. That wasn’t unusual, but it did signal a premature end to our 7-hour dive to [...]

But when you zoom in and look even at the coarse detail that the ship’s multi-beam sonar can reveal, [...]

ABOARD THE R/V THOMAS G. THOMPSON—Our operations have been halted for a second day now while we wait for a storm on the other side of New Zealand to spin itself out. With no samples to process, many of us took a day off to catch up on reading or, for some of the undergraduates [...]

Humans have been to every corner of the planet and built either an Internet café or a Starbucks in almost every city. You can find plastic in the middle of the ocean and Mt. Everest base camp is a vast rubbish heap. Satellites monitor virtually every square meter of Earth every day and Google has [...]
