The Ocean Blog

Most people have never heard of the Hawaiian petrel , an endangered, crow-sized seabird that spends the majority of its life searching for food over the North Pacific Ocean. Nevertheless, this bird...
Salmon are one of the most widely loved varieties of seafood in the world. A ubiquitous alternative to meat and poultry, salmon wear a halo of healthfulness, as they are rich in protein and omega-3...
Sea stars are important members of marine ecosystems, especially in the tropics. We may think of tropical coral reefs as being home mainly to fish and corals, but in fact these habitats are home to a...
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...
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...
If you are a bird watcher you have probably heard of the Christmas Bird Count. The first one occurred on Christmas Day in 1900 at a variety of locations throughout North America, and it has since...
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...
It blew in for two solid days: a flotilla of plastic forks, soda bottles, rubber gloves, and other refuse. I tried to pick everything up off the beach, but when I turned around, you couldn’t tell...
When snorkeling in the Kahekili Herbivore Fisheries Management Area (KHFMA) in West Maui, I keep an eye out for certain kinds of fish. Not the brightest or the biggest, but those herbivores such as...
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...
Welcome to Citizens of the Sea , a new blog series where ocean life comes to life. Our book by the same name came out in September, but no sooner had it gone off to the printer than new ocean stories...
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...
Any floating object in the ocean tends to attract life; fishermen know this and deploy floating buoys to concentrate fish for harvesting. Plastic marine debris is no different and, at microscopic...
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...
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...
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...
I’m a high school student interested in pursuing marine science. I have loved the ocean since I was 3 feet tall and only getting my feet wet at the beach. I’m a senior in high school, and over 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...
