Much like scientists can read the rings of trees to determine climate changes that tree has endured, researchers can "read" coral. For example, by analyzing the coral's strontium-calcium ratio, scientists can measure how much rain fell as much as 6500 years ago. In a recent study, in fact, researchers with the British Antarctic Survey concluded that the periodic and normal increase in monsoons in the Indian Ocean paradoxically result in stronger droughts in Indonesia and Australia.

While this trivia may not have much import for the typical suburban mom, the implications of this research are fairly staggering. Simply, corals provide ...

You've seen the bloated contents of my dive bag so today we'll take a look at something more svelte. Marc Lyng's warm water setup is direct and to the point but not as flashy as Willy's. I envy you warm water divers but at least hauling my bag around is a good workout.

If you want details on the gear in the photo, head over to Marc's Flickr page and hover over the ...

While some people worry that fish populations are being exploited at a dangerous pace, others are rejoicing at the small successes that are occurring. In Australia, for example, the red throat emperor has made a spectacular comeback in recent years. Once heavily overfished, the fish seem to have rebounded. Why? ...

Recently, we told you about blue bottle jellyfish -- a.k.a., Portuguese Man-of-Wars -- washing up on Florida's beaches. This weekend, more than 160 beach-goers in southern Australia were stung after the jellies washed ashore on seven different beaches.

According to Gold Coast Duty Officer Kevin Dunn, "They are an amazing little ...

How do you donate air? There's more than one way to do it. That random dive buddy you ended up with at the boat dock might do something unexpected in an out of air situation. SCUBA Theory is back again. Today, it's all about sharing air.
How do you share? Divers naturally share air ...

Researchers in Madagascar recently concluded that closing marine areas to fishing for even short periods of time can significantly restore depleted fish stocks. The researchers found that after an area off the coast of the island was closed to fishermen for seven months, the number of octopuses caught later rose ...
