Top predators along the California coast are having a rough year. Recently starving sea lions have showed up on California beaches and are clamoring for fish at the mouth of Oregon's Columbia River...
My father once told me that the world is divided into two kinds of people: those who believe that the world is divided into two kinds of people and those who don’t. Wherever you come down on this...
Traveling aboard the Charles W. Morgan , a 173-year-old whaling ship on its 38th Voyage, I’m struck by its paradox: this vessel which spent years chasing and killing whales is now helping us to study...
Marine parasites may be small in size, but they can be present in very high numbers and put together can weigh even more than all the top predators in an estuary or bay ecosystem! They play an...
Very few plant species can survive close to the ocean, where pounding surf fills the air with tiny salt crystals. Too much salt is not good for us, and it is not good for most plants. When you think...
The pre-industrial American landscape was once rightly described as a place where “the deer and the antelope roam.” On land, we take it for granted that the plant-eating deer and antelope far...
I am once again leaving my familiar world behind and descending into the abyss below. The first dive of an entirely new expedition is the most magical. I am a member of a scientific research dive...
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...
A great surf photograph appears loose and improvised, like the waves and surfers it depicts. The reality is less spontaneous. The photos that you see in surf magazines rarely happen by accident, and...
Whales swimming in the ocean are never really alone. Even if one swims by itself with no other whales for miles around, it still has company—the tiny microbes that live on its skin. For a long time,...
For those of you who have had the opportunity to visit a coral reef , you know that it’s an experience you are unlikely to forget. Coral reefs are among the world’s most magnificent ecosystems. Their...
Sometimes called the rainforests of the sea, coral reefs are incredibly diverse and complicated systems. Because of this complexity, it can be a challenge to manage and protect reefs—and sometimes...
Many animals depend on their eyes to navigate, find food, locate mates, and for other important activities. But marine mammals often rely on sound—sometimes far more than sight—for such critical...
As far back as I can remember, I have always been fascinated by sharks. My father introduced me to the ocean through books, documentaries and diving, and whenever we would see sharks on a dive in the...
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...
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...
Sunday, November 21 marks World Fisheries Day , an annual occasion observed in many fishing communities around the world. It’s a great opportunity—even for those of us who do not fish for a living—to...
I took this shot at Pfeiffer Beach, my favorite beach in my home state of California. If you aren't familiar with it, it is a very secluded beach in Big Sur where we have some of the most spectacular...
