Beneath a British Columbian Waterfall?

Greenpeace Vessel M/V Esperanza

Greenpeace Vessel M/V Esperanza

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.” [Read more...]

You’re an Ocean Doctor!

Ocean Doctors Like to Make Housecalls!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.

Next-Generation Aquaculture: The Future of Fishing on Planet Earth

After being nearly ignored for decades, marine conservation issues are increasingly at the forefront of the environmental agenda today, thanks in large part to the report of the U.S. Commission on Ocean Policy and subsequent U.S. Ocean Action Plan as well as the results of the independent Pew Oceans Commission, and current actions of the Joint Ocean Commission Initiative. The similarity of the findings of these efforts has been striking, recognizing that urgent steps are required to restore marine ecosystems. Among the most serious problems cited is overfishing and the recognition that U.S. fisheries are increasingly unsustainable and many populations will take decades to recover.

Of course, this trend is not limited to the U.S. and global overfishing is viewed as one of the principal causes of the loss of integrity of marine ecosystems and is considered a major factor in the decline of coral reef communities. [Read more...]
