Greetings from aboard the Greenpeace ship, M/V "Esperanza"!
We're anchored beneath a beautiful waterfall in one of British Columbia's magnificent "fjords" to prepare for this summer's intensive expedition to the Bering Sea.
Greenpeace's largest ship, the Esperanza, will be visiting the Bering Sea in Alaska for most of the summer.The expedition will be using manned submersibles and an ROV to survey Zhemchug and Pribilof Canyons, specifically to map and document deepwater corals living at depths of more than 1,000 feet. These corals, some hundreds of years old, are vital components of a healthy marine ecosystem. Unfortunately, these corals are at great risk, ending up in trawling nets as "bycatch." Many tons of corals have been destroyed by this indiscriminant fishing gear. It is our hope that the data collected on this expedition will help advance our scientific understanding of these deepwater coral communities and be helpful to policy makers as well, leading to more effective conservation measures. A Scientific Advisory Panel is advising the project, including representatives from Scripps, the Smithsonian, the St. George Island Ecosystem Office, MCBI, Oceana, Texas A&M, and Nova Southeastern. I've been asked to serve as a submersible pilot and scientific advisor.
We're using two DeepWorker submarines, 1-person mini-subs, untethered, that are capable of a depth of up to 2,000 feet. The sub is equipped with high-definition video, a manipulator arm for collecting samples, sonar for navigation and is always in contact with the surface using through water (acoustic) communications. DeepWorker uses CO2 scrubbers, similar to what's used in spacecraft, providing up to 80 hours of life support. A typical dive lasts 4-6 hours.
The expedition is scheduled to begin in Dutch Harbor, Alaska (in the Aleutian Island chain) in mid-July. We are spending this week aboard ship near Vancouver training additional pilots, planning the expedition, and preparing the ship and crew for work in the Bering Sea.
Thanks to a satellite uplink, I am able to access the Internet when there are no mountains blocking the ship's view of the satellite. The ship is very comfortable, excellent food, and my personal favorite amenity, an espresso machine.
Yesterday we practiced launch and recovery operations. Today we're working through emergency drills at shallow depth. Our ship is being guarded by a fleet of four Canada geese who dutifully orbit the vessel every 5 minutes. Lots of harbor seals are also checking us out. Spotted a double rainbow on Saturday -- this is considered very good luck, especially aboard a rainbow-adorned Greenpeace ship.
During our long road trip to the university where my daughter would soon begin her first year, I was recounting that same period of my life and the fact that my parents had really wanted me to be a doctor....an M.D., that is. I hated to disappoint them, but I tried to explain that I wanted to pursue my true passion, marine biology.They were troubled that I'd never be able to make a "real" career out of this passing fancy, but 30 years later, I suppose I have. My daughter chimed in, "But you are a doctor. You're an ocean doctor!" Funny, but I had never thought of it that way. Yet I have spent much of my career studying and diagnosing what ails the oceans and advocating policies to heal them. So I looked at her and said, "I like that. I think I might use that some day." So, here it is -- please accept my warmest welcome to OceanDoctor’s blog, dedicated to the wonder of the oceans, being true to your dreams, and, of course, my daughter.
