Sustainable Seafood

- Adam Clare 1 Comment

Greenpeace recently ranked grocery chains in how environmentally friendly their seafood is (full report as a PDF) and it seems that grocery stores are responding. Giant Food is already changing their way.

Giant Food announced support for the principles of the Conservation Alliance for Seafood Solutions, a coalition of nonprofit groups that works with retailers to change the way they buy seafood.

Giant said it is committing to work toward buying environmentally responsible products, making information on seafood products readily available and supporting policy changes that have positive environmental impact. The company’s seafood buyers are now also ranking their purchases on how plentiful the species is, how it is caught and what effect fishing has on the species’ natural habitat.

Whale Songs to Warn Mariners of Their Presence

- Adam Clare

A system of buoys that will warn boats of the presence of whales has been put in place along a part of the east coast of the USA. The network of buoys listen for sounds that whales make and then the network will relay messages to boaters in the area to stay clear of the undersea creatures.

They have developed a cutting-edge underwater listening system to protect the creatures from their number one killer: ships. The Massachusetts Bay network can track right whales by their signature call – and in as little as 20 minutes warn mariners to slow if they’re too close.

The devices are also giving scientists unprecedented insight into how the creatures change behavior to respond to the cacophony of man-made noises in the bay.

“We need to listen to these whales” to save them, said Christopher W. Clark, director of Cornell University’s Bioacoustics Research Program, which developed the technology with Woods Hole Oceanographic Institution.

Clarks said an increasing number of pipelines, cruise ships, tankers, and construction projects are drowning out the whales’ soft calls, making it difficult for them to connect. Clark has evidence that the whales simply don’t “whoop” when the bay gets too noisy.

“In the world of right whales, we know it’s a noisy place to live,” Clark said in an e-mail. “Underwater [is] not much different than living on the tarmac at Logan.”

Wave Powered Boat to Travel on Waves

Kenichi Horie, who has traveled on a solar powered boat, will now travel across the pacific on a wave-powered boat. Strange, but true!

The boat made of recycled aluminum relies on the energy of waves to move two fins at its bow and propel it forward. Horie said it is a sturdy vessel, designed to right itself if it capsizes. But it is equipped with an engine and an 11-metre sail mast for emergencies.

The journey – which would take a diesel-powered boat about 10 days to complete – is expected to take Horie about 2.5 months. He will take along rice, canned food, microwaveable meals and beer.

Solar panels atop the catamaran will power the microwave and Horie will also have a satellite phone and access to e-mail.

Japan Stops Whaling

This is without a doubt, really reat news. Japan has halted whailing for the year, after pressure from the Australian government. A hat tip to Kevin Rudd and his fellow Aussies for convincing Japan to change their ways.

The country’s chief government spokesman, Nobutaka Machimura, revealed the backdown at a news conference today.

Japan had planned to harpoon 50 humpbacks
He said: “Japan will not hunt humpback whales.”

The country had planned to harpoon around 50 humpbacks on its current expedition, the first time since the 1960s that Tokyo would have hunted the species, which are popular with Australian whale-watchers.

Mr Machimura added: “It’s true that Australia expressed quite a strong opinion to Japan on this.

“As a result, I hope that this will lead to better relations with Australia.”

Greenpeace Tracking Whale Tails

- Adam Clare

Greenpeace is tracking the movement of whales to monitor their safety and help science. You can track the whales online using Google maps. From the Greenpeace whale tracking announcement:

Today we launched the Great Whale Trail, following the migration of humpback whales from the warm tropical waters of the South Pacific, where they breed, to the icy Southern Ocean around Antarctica, where they feed. And we’re doing it via satellite tracking and Google Maps. Nifty.
