Operation Deep Scope: Seeing with "New Eyes"

August 7-17, 2004

News Flash: camera icon The Eye-in-the-Sea camera captures a squid for the first time.

The deep sea is a dark frontier. Many of our attempts at shedding light on the mysteries at the ocean's depths have been clouded, at best. What we can't see can elude us. How many marine animals have swum out of our nets? Evaded our bright and noisy submersibles? Or simply escaped our notice? In order to discover these creatures, and learn more about how they have adapted to life in the ocean darkness, we must explore in new ways. Earth’s final frontier demands that we see with "new eyes."

Operation Deep Scope was dedicated to seeing with “new eyes." This cruise, aboard the R/V Seward Johnson II, featured the use of new and one-of-a-kind equipment. The innovative and advanced camera systems, for example, made it easier to see animals under extremely dim light, without disturbing them. We also deployed newly designed light-tight traps in hopes of bringing some deep-sea animals -- perhaps ones we've never before seen -- to the surface, alive and with their remarkable eyes intact.

The site of this exploration, the northern Gulf of Mexico, is one of the most geologically complex regions on the planet. Consisting of basins, canyons, escarpments, and seeps, this region is far-better suited to exploration by submersible than by traditional sampling with nets and trawls. It is also an area of intense biological interest, thanks to the recent discovery of rich communities of tubeworms, associated predators, and other organisms, whose food web is based on chemicals from methane seeps (rather than sunlight).

The Operation Deep Scope science team explored each of these sites with our “new eyes.” We measured and characterized the light, both from the sun and bioluminescence, which was found in these ecosystems. Light has been described as the most powerful selective force in evolutionary history. Understanding how animals have adapted to the light in their environments -- to see and be seen (or not be seen) -- will provide new insight into the nature of life in these unusual communities.
