Whale Watching!

On Friday 08/01/14, the class went whale watching as our last field trip. Before the boat took off everyone was very excited for the trip ahead, but then... the boat started moving. Unfortunately, then not everyone was not so happy. Sea sickness decided to make its way into some on our classmates, and our TA. But, it was all worth it, when we got to the whale watching site we were very informed by our guide that we were about to see Humpback Whales. We saw two Humpbacks, North Star and Hippocampus, they are identified by the marks on their tails.

They weren't very active because they were diving down for food. They dive and stay without breathing for about 4-5minutes at a time to collect their food like plankton and krill. They were very focused on gathering food because when mating season comes around, they travel south to the golf, where there isn't much food to eat. Over all, although they whale weren't very active, they were still an amazing site to see.

Assignment Part 2 - The Mysterious Shells

When we discovered the colorful shells on a flat large rock, at first it was not quite so obvious what they were. After some more exploring we learned that they were in fact either Brown Lipped Grove Snails (Cepaea nemoralis) and/or White Lipped Land Snails (Cepaea hortensis), which are close relatives of the Brown Lipped Grove Snails.

After much consideration, which included ignoring the fact that it was in fact and research I found out that the shells, which were broken when found on the rock, got there from one of their largest predators, the Song Thrush. The Song Thrush will use a flat rock, also known as a Thrush Anvil, to smash the snails onto the rocks in order to break the shell and eat the snails.

I used a source from University of Michigan for my research. http://animaldiversity.ummz.umich.edu/accounts/Cepaea_nemoralis/

Underneath the docks at the Barking Crab

During class on 7/13/14, we were instructed to break into groups and look at a section of a dock behind the Barking Crab, I was a part of Team Barnacles with Stephanie and Cathrine.

We, as Team Barnacles, chose to explore an area of the dock that was in the shade. We saw a vast amount of plant life and animal life, and for our assignment we decided to focus on 16 plants/animals that we thought we could identify. The first very noticeable plant that I would like to discuss is the deep green leaf that attaches itself to the side of the dock.

It seemed to resemble lettuce, and after much research we decided that it is Ulva Lactuca. We also noticed this red/orange plant that grew on the dock, and under the dock. After scraping some of it off and into a cup we noticed that it seemed to have a porous and spongy quality.

After much talk of what it could be, we agreed on the Velvety Red Sponge. Also in the picture above is what seems to be a "fluffy tree", as Stephanie called them. After looking through the guide book, we decided that it is a Frilled Anemone. We also noticed a longer plant, that seemed to be pinkish in color.

We came to the conclusion that it is a Wine-glass Hydroid, since it was pinkish brown in color, and was fluffy and long. Next, we noticed two types of seaweed, which are in the picture below.

The seaweed that is located above my hand is thought to be Fucaceae. We also believe that the seaweed located below my hand is Knotted Wrack Seaweed. Then we noticed the mussels that have attached themselves to the dock.

They are Blue Mussels, and when we looked at one of the mussels more closely, we noticed a somewhat orange colored plant that looked similar to a honey-comb, which we decided was a Golden Star Tunicate.

We then noticed a little creature that was sitting on one of the mussels we took out of the water to look at. We placed the animal in a cup of water and examined the organism and decided it resembled a shrimp of some sort.

Then we added some plant life in the water, which the animal seemed to respond to as it began swimming around more. We also noticed that more shrimp like creatures were attached to the plant life that we added in the cup.

We decided that these little shrimp are Hyallela Azteca. Then there was another organism in the cup that was on a piece of plant life. It almost looked like a stick, and seemed to be able to bend due to 5 joint like sections on its body.

It looked like a Smooth Skeleton Shrimp, it is located in the picture above on the left-hand side of the cup. We also saw a lot of barnacles that we identified as Thatched Barnacles. After we were done exploring the side of the dock, we got to explore the animals that were caught in a lobster cage.

We decided that the crab seen in the picture above is a Jonah Crab. We also saw another type of crab that we decided was a Common Spider Crab. Also, the jellyfish that the Common Spider Crab is eating, that we saw floating around in the water as well is a Moon Jellyfish.

There were also lobsters that we thought could be Northern Lobsters.

Lastly, we saw a starfish that happened to get caught in the lobster cage. We decided it was an Asteroid Sea Star.

First Day at Boston Harbor

We arrived at the Boston Harbor at roughly 2:00pm on 7/12/14, and my first impression is that the harbor is teeming with life. We started off observing the ducks on the water and feeding the Striped Bass fish bread crumbs.

I also noticed that there were also small jellyfish in the water as well. We then moved on further to see a broad view of the harbor, which was when we noticed more bird life that seems to live near the Boston Harbor.

It was entertaining to watch this bird dive underwater to fish for food. From researching birds that dive underwater, and then searching what birds live in Massachusetts, I have deduced that this bird is either a Double-crested Cormorant or a Great Cormorant. We also noticed tide pools, and plant life that exists in the Boston Harbor. There were also Jellyfish that accidentally get pushed into the tide pools from winds and tides.

Then roughly thirty minutes later, we began the boat trip with HBC around and outside the Boston Harbor. I noticed many of the islands that we talked about in class today. Such as Deer Island, which has the egg shaped buildings that holds human waste.

On the way to George's Island we say a boat stranded on Nix's Mate, an area that was once and island and is now mostly submerged, unless the tide is low.

We then took a stop at George's beach, where we admired the people enjoying the beach and fort.

As the boat ride continued, I noticed the wind power turbines that are around the Harbor.

On the way to Hewitt's Cove, Prof. Berman decided to man the boat.

When we arrived in Hewitt's Cove, the thing I noticed most was the new condos that seems to take away from the natural environment, and the remnants of a navy shipyard.

Then, on the way back to Boston Harbor we noticed the same boat on Nix's Mate, but since the water receded more, it was more apparent at this point how truly stuck the boat was.

Overall, my first impression of the Boston Harbor was that it have improved greatly from the hardships of pollution. The Harbor and the outer islands are highly populated with humans, fish, birds, and plant life. It is clearly a beautiful example of functioning marine biology that I cannot wait to explore further.

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.”
