Navigators From The Marshall Islands Used Wave Charts To Guide Their Way

For the untrained eye, the sea only looks like a featureless expanse of water. But for master navigators of Oceania, the sea is full of signs and clues that could help them reach their destination — from driftwood, birds, and even the direction of the waves.

Navigators from the Marshall Islands use wave charts to travel through the small islands and atolls in the region. These charts, which capture the distinctive patterns of ocean swells, are a result of constant observation of the sea from land. But as these are not maps, they are not brought to sea. Instead, the sailors memorize these stick charts.

Wave charts have three types: the rebbelib, which show whole island chains; meddo, which represent ocean swell patterns in small areas; and mattang, which teach basic interactions between land and sea.

The wave charts have been a crucial element in making the Pacific Ocean trade routes possible. These routes stretched "at some points all the way from New Zealand to South America." Now that's bonkers!

I unloaded 40,000 bricks by hand once. No tangible fingerprints for a fortnight or so, but interestingly I did still leave a print from the sebaceous glands which were still there and while follow the patterns of the (missing) prints.

Man, going into the US you have to give everything but a urine test. this guy shouldn't have had to give his fingerprints in the first place.

All people coming in should not be guilty til proven innocent. I feel like this is such a violation of rights.

On a blog (like it is here), this is interesting. When it's reported all over the major news channels (like it has been the past week or so), one starts to wonder how such a near-inconsequential story gets picked up.

This happened to Mother last year when we were flying in to Newark. She had just finished treatment for breast cancer and her fingerprints didn't match up to homeland security records. She was detained for several hours, but was eventually allowed to proceed after one of the officers on duty said his wife had had the same thing happen to her

When I used to climb 5 days a week, I lost my fingerprints altogether. I always thought it would've been a good time to commit some crime. (Of course, I guess I could just wear gloves for the same effect.)

I hope they don't do this to citizens of the US. I work with a law enforcement agency and I do not take this drug, but I do not have fingerprints. They can get 2 or 3 partials with the laser fingerprint machines, but they don't get even that much with ink. It is a natural condition.
