Lovells Island

Date: August 2, 2009
Time:10:19am
Temp: App. 80 degrees

Hi,
Our second day on the ocean was to an Island called Lovells Island. We departed Boston Harbor at about 9:40am and we made our first stop at Georges Island. From Georges Island we took a water taxi to Lovells Island. At Lovells Island, we met two guards who explained the nature of the island and how the shape looks like. One of the guards explained that the island looks like a "ram". From there we continued our trip to a beach called Cobble beach still on Lovells Island. There were a hole lot of rocks on that beach and Bruce explained to the class that there are different kinds of beaches. Cobble beach was basically a rocky beach and Bruce used the term "Brazil nut phenomenon" to explain how the rocks were laying on each other. We saw that bigger rocks were on top and smaller rocks beneath. We discovered that there were really huge rocks but we can into conclusion that those huge rocks were man made and Bruce explained that those rocks are used to prevent storms from destroying the island.At the beach, we gathered different kinds of shells and we discovered that some of the shells had holes drilled in them. We gathered a lot of periwinkles and also we found some live ones. Most of the live ones looked alseep but Bruce told us to sing to them so that they stay awake.Some periwinkles really responded to the sweet melody of some of us and we got the chance to see the live periwinkle moving from its shell.
One of the students found a strange periwinkle at the shore and me and two other students can into a conclusion that that periwinkle was an invasive creature. We discovered that it was Chink snail with the scientific name"Lacuna Vincta".
Now we were left with that question of what made the holes in the periwinkle. We discovered that star fish eats snail and mussels so i think that these predators such as crabs, and star fish can be attributed to the holes drilled in these periwinkle.
From the cobble beach, we moved to a salty and marshy area and we were told that some plants on that area are considered invassive. We pulled out a plant called Pepper weed and we were told that that plant is invassive. We then moved to the tidepool catch green crabs. We found alot of green crabs under rocks near the shore of the ocean. We then moved back to an area where we were supposed to be looking for black berries but one of the students found a snail shell, so our mission of looking for black berries changed into looking for snails. We found both dead and live snails and most live snails were on trees while that dead ones were laying on the floor. We then moved back to the tidepool to find some lobsters. Interestingly, the group I was working with kept moving a liitle deeper into the ocean and we caught a big lobster.
At the end of our discovery, we gathered all the snails and we discovered that the snails had different patterns and different colors. We were asked to answer why the snails have different patterns. My observation was that the dead snails had brownish patterns and the live ones had yellow colors. The differences in the patterns can be attributed to the habitat of these snails. Different snails from different habitats have different colors and different patterns. These patterns on the different snails somehow helps them to hide from their predators. One of the snails that i observed is believed to be "Cinammon roll". We then headed back to Boston at around 3:45pm.
Cheers,

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.”
