The year 2010 will likely be remembered as a tragic time for the ocean. Yet, despite the oil disaster in the Gulf of Mexico, I have hope for our ocean’s future. Last week President Obama signed an...
It’s hard not to identify with penguins as they waddle about upright on land, clad in their tuxedo-like plumage. In their crowded breeding colonies, they squabble with and show off to their neighbors...
Lying in water only a foot deep, I watched the shark meander lazily through the mangrove, already exuding the confidence inherent of the supreme creature within its domain. It was hot here in Bimini...
Even on an early winter morning, it was sunny and warm in southern Florida. This was great because, regardless of the weather, Dr. Jon Norenburg and I were going to walk chest-deep into the water to...
Bacteria are everywhere in the ocean. They live in the water, on virtually every living and non-living surface, and even inside other organisms . There are 1 million bacterial cells in every...
When we think "Africa," we think of the "Big Five"—lions, elephants, leopards, buffalo and rhinos—that crisscross the African Savannah. Few would imagine that there could be more natural beauty on...
Since the dawn of seafaring, humankind has had to deal with the pesky creatures that settle on ships—seaweeds, barnacles, and others that take advantage of the empty real estate provided by a clean...
I became interested in weather phenomena when I took physics in high school. At the time, I just wanted to understand how various things in nature worked. Unfortunately, most information about...
In 1872, the United States did something remarkable. We set aside one of our greatest natural treasures, Yellowstone National Park , for future generations to enjoy and appreciate. The logic was...

Diving can be a wild ride that evokes more than a little trepidation, especially in the Pacific Ocean's famously big, cold waves. Waves that are otherwise fun for my weekend surfing can turn a...
With 1,400 named species of ribbon worms inhabiting every ecosystem on earth, seeking one out should be an easy proposition. But I quickly learned that it can be quite daunting when you’re looking...

The blanket octopus can rip a poisonous tentacle from a Portuguese man-o-war and wield it like a sword to ward off enemies as it soars through the ocean trailing its webbed cloak behind it...
Reef biologists over a certain age are haunted by memories of what glorious places Caribbean reefs once were. In our youth we studied them for all sorts of reasons but scarcely thought about reef...
