Over 15 years of ocean science and conservation online
In a world where greenwashing, overfishing, bycatch and pirate fishing run rampant, it can be difficult for eco-conscious consumers to know what to buy. Many eco-certification agencies exist, but they often offer conflicting advice. Who should you listen to?

I adored Song for the Blue Ocean. The first time I read it was a formative moment in my development as a young marine biologist and conservationist. When I picked up Eye of the Albatross and, later, Voyage of the Turtle, I expected that same magic, but could not find it. Safina’s subsequent books were not bad. Both were evocative, beautifully written, and stirring tributes to the natural world. But their stories felt too familiar, like listening to a contemporary symphony built around a Bach fugue or watching a remake of a classic movie. So I approached The View from Lazy Point with the same expectations, as yet another supplement to Song for the Blue Ocean. I was mistaken.
The term sustainability is a muddy one, covered in marketing efforts and political baggage. So when someone says they study sustainability or are part of the field of sustainability science, what does that mean? The discipline actually refers to a fairly well-defined subject borne out of the call for interdisciplinary research, especially between ecology and the social sciences. At its heart, the field is based in the need to provide food, fuel, and fiber to current and future residents of planet earth. In other words, it’s the science behind the Brundtland Commission’s oft-cited goals of sustainable development and hopes to understand and create long-term integrity of the biosphere and human well-being.
This 2011 Beneath the Waves Film Festival entry comes from students of Dr. Jeremy Long, the creator of “What Invert You Like“. If you have a question for the filmmakers, please leave it as a comment below and I’ll make sure they get it. This entry won “best student film”.
Earlier this month, a video of fishermen shooting a rifle at sharks appeared on YouTube and caused quite a stir. The video has since been removed, but not before shark conservation activists made copies (warning: the videos are extremely graphic and have inappropriate language). Apparently some computers can access the site with the videos and others can’t, if you can’t access the site and want a copy of the videos just let me know. All images in this post are screenshots from the video.

Last summer, I reviewed National Geographic’s “Expedition Great White” and interviewed the lead scientist. Several researchers and conservationists were concerned about the methods that Dr. Michael Domeier uses to study great white sharks, particularly after one shark was “foul hooked” through the gills. These methods (removing captured great white sharks from the water to study them using a forklift-like structure) make for excellent television, but may be harmful to the sharks. As I reported last year:

In this week’s edition of Shark Science Monday, Matt Baronio of Southern Cross University discusses using Remotely Operated Vehicles (ROVs) to study shark behavior. If you have a question for Matt, please leave a comment on this post and I’ll make sure he gets it.
This year’s Beneath the Waves Film Festival was a huge success, and we’ve already started planning for next year. In the meantime, I’ll post some of the 2011 entries. “Spectacular when spotted” follows a spotted eagle ray research project in Bermuda. It has some great footage of these amazing animals, and shows some field scientists … Read More “Beneath the Waves Film Festival: Spectacular When Spotted” »
Last week, the Indian Ocean Tuna Commission held their annual meeting in Sri Lanka. As one of the few international fisheries policy organizations in the region, the IOTC is also responsible for management of billfish and sharks. Several new shark conservation policies were proposed this year. These included species-specific protections for hammerhead and oceanic whitetip sharks, closing loopholes in existing policies that ban finning sharks and discarding the bodies at sea, and requiring fishermen to collect and report more types of data on their shark bycatch. All of these proposals were rejected.

In the lecture we just posted, Keith Rittmaster mentioned that Sperm Whales are highly asymmetric. Below is just one examples of this dramatic asymmetry, the size difference between the left and right nostrils in the cranium.
