About the Author

Visiting a Maine beach in March 2010, Harold Johnson was shocked by the ocean-borne debris left by recent storms. He grabbed a garbage bag and a camera, and hasn’t looked back.

Since then he has spent most of his free time studying marine pollution, coastal ecosystems, and the mysteries and science of ocean and shore.

Copyeditor and writer by trade, historian and archaeologist at heart, Johnson’s philosophy is simple: Dig below the surface, travel the currents, make the connections, learn. Then share what you learn. He lives in Saco with his wife and young daughter. Follow on Twitter @FlotsamDiaries.

Looking back on a year of posts, two themes weave their way throughout “Undercurrents.” First, the only species capable of flat-out destroying the beautiful & vital places on earth is man. But second, the only species that can actually appreciate and value the beautiful places of the world is man.

As a writer, and a dad, my moods tug me toward the one theme and then the other. I’ve studied enough of our shortsightedness to see how easily we bury our heads. We claim that grocery bags are immensely valuable, yet balk at paying 5 cents for them to fund anti-pollution efforts. We pull fish out of the sea at an unsustainable rate and know it, yet balk when conservation efforts try to stave off disaster.

Yet we are also the only species that can marvel at a misty sunrise on a deserted shore, clean dewy sand under our toes. We’ve learned how interconnected and interlocking the world actually is — how our rivers churn the seas, bloom phytoplankton in spring, which becomes food for the fish we eat and oxygen for the air we breathe. How the ocean is a huge conveyor belt of nutrients and heat that covers the globe and connects us all. Here in Maine we're fighting to protect our waters and wetlands, and return fish to our rivers. In our hearts, we "get" it. We’re the only creatures on the planet who do. And we are, at our best, in awe of our world.

It would be very easy for “Undercurrents” to beat a constant drum of waste, pollution, excess, gloom, industry lies. There’s enough in the world to choose from. We can’t find a downed plane for all the derelict fishing gear and other huge debris in the distant ocean. Madness.

12-degree dawn aside, spring really is here. The hopping sugar house at Harris Farm’s Maple Sunday was proof of that.

But spring is happening offshore too. In the coming weeks, something magical -- and completely ordinary -- will start happening. Spring phytoplankton blooms will begin all along the shallow coastal waters of the North Atlantic.

These two stock NASA images show blooms in the Atlantic, the first off Newfoundland, the second off of western Iceland.

After a short break to catch up on a laundry list of other responsibilities, a return here to the blogosphere.

I’ve been reflecting on four years of flotsam fighting. I picked up my first bag of beach debris in early March 2010. My then-toddler daughter and I had visited Ocean Park just after some big storms. The beach was littered up and down with shells, wrack, and a shocking amount of plastic.

I resolved that day to do "something," though I didn’t know what.

Today, four years later, I still don’t know what. I do know now how naive I was. I had hoped I could do my part to keep the world’s beautiful places from getting fouled. But that’s already happened.

The Press Herald broke news last week that seven square miles of the Penobscot River were being closed immediately to lobster fishing thanks to mercury poisoning.

Arms were raised, people were shocked, accusations of coverups flew. The usual.

What else is “the usual”? Fishery closures in Maine because of pollution. If you've visited beaches in Maine, you've almost certainly seen one of these:

Today’s Press Herald has a fascinating story of the wreck of the RMS Bohemian off Cape Elizabeth 150 years ago. It’s a poignant reminder of the turbulent history of Maine’s rocky coast. And it’s also a window into the mystery and lure of shipwrecks.

According to the article, $1 million (in 1864 value) worth of goods went down with the ship -- pottery, cloth, buttons, pewter, gold-embroidered silk. As well as sacks of mail. Much washed up or was salvaged (and perhaps scavenged). But of course much never surfaced. There are surely still pieces of that tragedy rolling around the seabed in Casco Bay and the wider Gulf of Maine today.

The Gulf of Maine has over 700 known shipwrecks. Some ancient, large, & famous like the Annie Maguire at Portland Headlight.
