Periwinkles, shrimp and crabs....Oh My!

It was a day not so long ago, Monday, in fact. It was yet another beautiful day in Boston. Our class met at 8:30 at Starbucks, a space we have since learned is public. After a short discussion of our findings from the day before and a synopsis of the days prior, we started to discuss the days impending activities. Following Professor Berman's lead, we all boarded a ferry from The Long Wharf to George's Island. We then boarded a smaller water taxi that brought us to a smaller less inhabited and visited island Peddocks Island. In order to get there we had to cross the Hull gut. I never realized how close and accessible suburban parts of Boston were on a boat. Pretty cool.

When we arrived on Peddocks Island the ranger gave us a short history of the island and explained its present day uses. Explaining that people did indeed live on the island, but did not own the property made me think this was kind of a strange place. But i guess it makes sense because it is a park run by the DCR and they are doing their best to maintain it. After a short description of the island, we trekked out to the beach.

Finding ourselves on a sandy beach we immediately noticed huge differences in the environment. In contrast to the previous day's vertical riding tide, we could clearly witness the lowering of the tide as it descended out to the ocean leaving behind wrack lines documenting the different levels of tide. When we arrived at this site the high was reasonably high, but the tide was going out. These wrack lines were clearly defined by neat lines of shells and other debris. Mixed in with the coarse sand, we found razor clam shells, slipper shells, quahog shells, and periwinkle shells. While these shells suggest life in the area, we were unsuccessful in finding any living specimen in this sandy area. We later learned that this environment is less hospitable than say a cobblestone area. This part of the beach formed a crescent shape. As we wondered down the beach it bowed out creating somewhat of a point. At this point we noticed a change in the size of rocks that made up the beach. From that point on the rocks seriously increased in size. And that was not the only thing that increased. The amount of accessible living sea life also increased. Possible to find various types of seaweed and small sea creatures this area proved to be more interesting. Within the cobbles that made up this section of the beach we found small tidal pools acting as individual ecosystems. This area was much more vibrant with life because of the cobblestone's ability to hold the water for longer giving small arthropods, periwinkles and crabs a place to hang out or hide.

As the beach curved back in to a crescent inlet the beach returned back to its sandy self and was once again void of accessible sea life. After a short lunch and swim break we explored the area behind the beach. I believe this was mud flat. It was exactly how it sounds. A whole lot of mud in a flat space with not a lot going on. Perhaps this area would be more interesting if it wasn't all dried up. (Dried up salt marsh- mud flat shown above) This environment was a stark contrast to the floating docks we had observed the day before.
Detail -------------------------->

On the way back we each were required to find and hold a crab, periwinkle, and arthropod. We found these living individuals in the cobble area attached to rocks (periwinkles) under rocks (crabs) or swimming in mini tidal pools (arthropods). Good to know where everything presides so I know how to avoid them next time I go to the beach. Though harmless, I am totally scared of creepy crawlers like crabs, snails, and other small sea things.

We finished out the rest of our day with a nice water taxi back to George's Island where a bunch of people got french fries at Jasper White's Summer Shack where food is love! Our ferry ride back to the Long Wharf was quiet and relaxing. I think everybody was tired from a day of exploring, observing and learning.

From Snails to Whales

Welcome to Snails to Whales, Bruce Berman's blog focused on both the little and the big things that make Boston Harbor such an interesting and extraordinary place to live, work and play.

With 50 miles of protected water, four sheltered bays, seven river systems, 34 islands and a nine-foot average tide, Boston Harbor is one of the most diverse urban ecosystems in America.

This blog focuses on the flora and fauna of Boston Harbor and Massachusetts Bay - on the beach, the shore, and the harbor islands, and in the cleaner waters of Boston Harbor and Mass Bay - including this ecosystems most important species - people.

During the summer, it is also a place for my Boston University Students and my colleagues at Save the Harbor / Save the Bay to share their work and experiences.

Where I am coming from...

Love that clean(er) water
Learning about the Boston Harbor Cleanup from the waterway’s eyes, ears, and mouthpiece

Bruce Berman, aboard a ferry from Boston’s Long Wharf to Georges Island, poses a question to his students: “How clean is clean enough?”

He’s talking about the water below.

It’s a brilliant July day, with the smell of salt spray in the air. The sky is clear, and so is the ocean. But there was a time when Boston Harbor wasn’t so clean, when the stench of sewage assaulted the nostrils of anyone who went near it.

Berman is the communications director for Save the Harbor/Save the Bay, a public-interest environmental advocacy organization whose mission is to help restore and protect the harbor and Massachusetts Bay. He also teaches a Metropolitan College summer course called Politics, Public Relations, and Public Policy: The Boston Harbor Cleanup.

“The Boston Harbor Cleanup is an amazing success story, and I just love to share it with students,” says Berman, noting that the harbor’s “bad old days” weren’t that long ago. Those were the days when untreated human waste, syringes, condoms, and tampon applicators routinely washed ashore. The antiquated sewage treatment plants on Deer Island and Nut Island were so poorly designed and maintained that they flooded during even mild rainstorms, sending millions of gallons of untreated waste directly into the harbor.

Since then, bacteria counts in the water have decreased by more than two-thirds. Now the harbor teems with plants and animals, and people can legally dig for clams on Carson Beach in South Boston, which was unheard of in the 1980s.

“It was one of the filthiest harbors in America, and now it’s one of the cleanest,” says Berman. “What I’m trying to impress upon students is how this incredible comeback occurred, and how business, advocacy groups, environmentalists, and government can affect the outcome of large projects such as the Boston Harbor Cleanup through negotiation.”

Paradise regained

Berman points to the left as the boat cruises by the cleanup’s centerpiece: the gargantuan white egglike tanks of the Deer Island waste treatment plant, which in 1995 replaced the antiquated facility. The plant treats an average of 350 million gallons of sewage a day.

“And what comes out of the Deer Island treatment plant?” he asks. Berman, his booming baritone competing with the roar of planes taking off from Logan Airport, has a habit of putting students on the spot to see if they’re paying attention.

“The outfall pipe,” say several simultaneously. “Treated water,” chime in a few more.

“That’s right,” he says with a smile. “The plant separates the solid and liquid waste, and it pumps the treated water through the 9.5-mile outfall pipe, which empties into Massachusetts Bay. The resulting sludge is converted to high-grade fertilizer.”

Now Berman returns to his original question: “How clean is clean enough?” There’s no quick and clear answer to this one. “It’s a question that at the end of the day the federal courts had to decide.”

In 1985, a landmark federal court case required that the harbor’s beaches be made swimmable and fishable by 2000. Save the Harbor/Save the Bay was formed the next year to raise public awareness of the $4.5 billion Boston Harbor Cleanup. Sewer ratepayers in the 43 cities and towns financing the project cried foul over the prospect of astronomically rising bills, but because of the determination of environmental advocacy groups such as Berman’s, the cleanup was largely completed on schedule.

Berman says it isn’t finished, however. There are still frequent beach closures because the counts of Enterococcus bacteria exceed the federal and state standard for swimming. The culprit: filthy storm water and sewage, much of it from leaky pipes and illegal hookups emptying into storm sewers, and then into the harbor.

“So is the harbor clean enough,” the Springfield native asks his students, “when you can’t swim in it one out of five days in the summer?”

Work to be done

This summer the state approved one of the last parts of the cleanup: the construction, by 2011, of a 2.1-mile tunnel near the Dorchester and South Boston shorelines that will hold sewage and storm water during bad weather. It then will be pumped to Deer Island for treatment.

Berman is ecstatic over this development, the result of “tireless negotiation and consensus-building,” he says. “After 2011, we’re looking at beach closings once every five years, when there is a major storm, instead of once every five days.”

But he is not about to let his guard down. To say that he is a man obsessed with the harbor cleanup would be an understatement. Berman is also Save the Harbor/Save the Bay’s “Baywatcher,” and he lives on his 40-foot trawler Verandah. Polluters beware: if you’re discharging oil or sewage into Boston Harbor, the Baywatcher just might be watching.

He is quick to point out that his zealotry is not just on behalf of the harbor’s flora and fauna. “The harbor is for everyone,” he says. “If you’re from a working class or poor family in Boston, and you can’t afford a Cape Cod getaway in the summer, a clean harbor is important. The same is true if you’re a tourist vacationing in Boston or you happen to live in a pricey waterfront condo.”

Accordingly, Berman, who was a political consultant and contributing editor to the Phoenix newspaper before joining Save the Harbor/Save the Bay nearly 10 years ago, also teaches his students about the harbor’s role in the city’s economy. He points out that in the early 1990s, just a few ferries cruised the harbor’s waters. Today, more than 100,000 people visit its islands each summer, discovering their ecological and historic treasures.

“The best way to protect the harbor cleanup,” Berman tells his students, “is to make sure that the public has access to the resources and can see a return on its investment.”

Trevor Kosmolsick (MET’05) has lived in Boston for seven years, but until taking Berman’s course, he had never been to the waterfront. “I’ve also wanted to go camping in the area, but I never knew that you could camp on a few of the islands,” he says. “Bruce Berman is not only a great professor, but the ultimate tour guide.”

He also backs up his words with actions. Sometimes he takes off his shirt and dives in the water to demonstrate to passing boaters that it’s safe to swim. To show people on ferries that fishing is safe, he’s been known to grab one of the bluefish or striped bass he’s caught and (very carefully) plant a wet kiss on it.

“What I want everyone to understand is that investment in the environment really does pay off,” says Berman. “We’re willing to pay for a clean Boston Harbor, so we should enjoy it.”
