Journey of coral discovery!

Come along on a 1,000-mile adventure as researchers explore the depths of the Bering Sea and North Pacific Ocean along Alaska's Aleutian Island chain. Their quest: to record images of never-before seen deep-sea corals and create a comprehensive map of coral life along the ocean floor.

This site was created as a record of that summer expedition.

What's a research cruise like?
From July 24 to August 8, 2004, NOAA coral researchers invited Alaska Science Outreach reporter Sonya Senkowsky to join them on the R/V Roger Revelle, where she spent two weeks following the science team's progress.

Where were we?  
See notes on our location, weather conditions and sights as we moved through the Aleutian Chain, land of fog, albatrosses -- and volcanos. When there wasn't time for a full journal entry, Where Are We Now is the place we put ourselves on the map and jotted a few notes to let people at home know what was going on:

Shortly after dinner, Jason II dove into glassy seas; we are still surrounded by fog. The TV monitors show an even eerier landscape more than a mile below, where it looks as if someone stuck hundreds of oversized pencils, point down, into the mud.
