Following Expedition Blogs - Mining Gems

If there's an expedition blue blog out there we're probably following it.

The facinating world of our oceans is at your desktop each and every day. You never know what will catch your interest.

This caught our interest.

From the blog Oceans Watch Expedition, this post is called Aid Meets Tradition:

Chris comments: here in Moussau the community is still very traditional. I was interested to see how the fishermen use coral stones to weight their hooks to get down to 30 m where the bigger fish are.

They tie a piece of coconut palm leaf around the stone then put the hook through the leaf. When the stone hits the bottom a sharp tug pulls the hook out of the leaf leaving an un-weighted hook on the bottom. The bait they use is a piece of condom!

The condoms are supplied to the communities free by a family planning NGO. All the fishermen we met used condoms as bait and are very grateful to the NGO for endless free lures!

Scott Cassell - Undersea Voyager

The Undersea Voyager Project is one of our favorite submersible/conservation efforts right now. Recently the team was in Lake Tahoe making news and discoveries:

SOUTH LAKE TAHOE, Calif. — A team of submariners that spent the month of May exploring Lake Tahoe and examined, among other things, evidence of an earthquake fault that may have ruptured thousands of years ago, is hoping the operation is just the beginning of their underwater explorations.

Scott Cassell, the sub's captain and founder of the non-profit Undersea Voyager Project, says his team has plans for a five-year mission to gather information and develop ideas to help restore endangered bodies of water around the world.

The goal, Cassell says, is to collect data and attract sufficient attention to prompt people and governments to halt pollution and overfishing and take other actions to protect threatened bodies of water.

A two-person submarine spent the past month cruising Lake Tahoe, examining earthquake faults, ancient submerged trees and beds of invading clams that threaten the lake.

"I think it's a very useful tool," said John Kleppe, a University of Nevada-Reno scientist who for years has researched submerged trees, some more than 3,000 years old, in Fallen Leaf Lake just west of Lake Tahoe. The trees, which grew when the lake level was lowered by lengthy drought, provide a "very good record of climate change," Kleppe said
