Life Clings to and Thrives on this Rock

PHOTOS BY JACK SULLIVAN You would think Mount Desert Rock, a 3-acre chunk of granite some 25 nautical miles off Mount Desert Island, would be barren, but the island is teeming with life, bursting with stories. You just have to know where to look. Coming from an inland eye, Mount… SEE MORE

The Strange World of Jellyfish

Around dusk one summer evening more than 60 years ago, I was looking over the stern of an anchored lobster boat into flat calm water off Old Orchard Beach. I could just make out the sandy bottom, where I was hoping to spot crabs. There was barely a swell, I remember. I was waiting on the boat for my father to return in his seaplane, which he used to spot herring for the sardine seiners. He often left me on boats for hours at a time while he flew off peering into Casco Bay island coves, and I was left to the boyhood devices of my imagination to pass the time. I don’t know what we were doing as far south as York County that evening. But just below the surface, translucent white moons about a foot in diameter began to appear. First one, then two, then I saw there was a whole smack of them floating at different depths. SEE MORE

How Far Can a Fish Run?

It’s not rocket science. “Take a freshwater fish, put it in salt water, and you’ve killed it. Take a marine fish, put it in fresh water, and you’ve killed it.” So says Justin Stevens, a sea-run fish specialist at Maine Sea Grant while describing the wonder of sea-run—or diadromous—fish. Like most organisms, fish require a strict regulation of salt within the body to function, so if a fish’s habitat is either too salty or not salty enough, it dies. Diadromous fish, however, challenge this conventional wisdom in that they thrive in both salt and fresh water. SEE MORE

What We Saw Touring the Gulf of Maine Shore

In 2002, Natalie Springuel and Richard MacDonald, among others, embarked on a paddling expedition along the shores of the Gulf of Maine. What they learned reveals how dynamic and threatened is this “semi-enclosed sea.” The Gulf of Maine Expedition was a sea kayaking journey organized to raise awareness and caring about the ecological and cultural legacy of this vast international watershed and to promote low-impact coastal recreational practices, safety, and stewardship principles.

The Unique Environment of Island Forests

photos by Jack Sullivan Imagine being at sea for weeks, months, or years, seeing only blue, gray, and the foaming white of cresting waves. Imagine smelling only salt, minerals, fish, and then, one day, catching the faintest scent of something different, like honey mixed with cinnamon and turpentine. On the… SEE MORE

The Misunderstood Shark

“Bastid took m’ hook!” Carts, a wiry guy with a cockeyed green cap and gaps in his smile, looked down at me from his precarious perch on the gunnel of the boat. I was about nine years old, and taken aback by his anger about the hook. We were on… SEE MORE

All eyes on the Chesapeake

The Chesapeake Bay’s past is the stuff of legend: Pocahontas and Capt. John Smith (well, actually John Rolfe), the rockets’ red glare and the anthem it inspired, the Monitor and the Merrimack, oyster pirates and the “Oyster Navy.” The future, though, is shaping up to be the stuff of hard… SEE MORE

The Strange Nature of Horseshoe Crabs

Ages ago in the sea-green clear water of Chandler’s Cove on Chebeague Island, strange dark shapes were scuttling around the bottom. My seven-year-old face peeked out over the edge of the wharf, watching them. I remember my hands gripping the splintery planks. Horseshoe crabs, the big people called them. Gliding… SEE MORE
