Celebrating Mary A. Whalen's 83rd Birthday

Yesterday was the 83rd birthday of the small coastal oil tanker Mary A. Whalen (photo above). She is owned by PortSide New York, a not for profit organization that has as its purpose to demonstrate "new ways to bring urban waterways to life."
PortSide threw a birthday party for Mary, with educational events, art and activities for kids. 
Emma Garrison (photo above, holding a horseshoe crab), a graduate student in the School of Environmental and Earth Sciences at Queens College of the City University of New York, gave a lecture on marine life in the estuary that includes Mary's dock. Standing to Ms. Garrison's right (left in the photo) in a red shirt is Carolina Salguera, PortSide's founder and executive director.

Before Ms. Garrison began her talk, a large container was lowered over the ship's side down to the water's bottom. It was hauled up after some time, covered in muck and strands of seaweed. Crew members sorted through the mess, and came up with some interesting creatures.
Among them were several tunicates (photo above), "colony animals" (each spot on the surface is a separate animal) that filter their food from the water. Also found were some other tunicates called sea squirts, which were shaped like little bottles with mouths and, when squeezed, would squirt water, to the delight of the children watching.
Another creature found was this little Asian shore crab. Ms. Garrison said these arrived here in the ballast water of ships that came from Asian ports. The haul also included some marine worms, mussels, and an oyster.
After Ms. Garrison's lecture and demonstration, a woman who introduced herself as Cat, a librarian, did some songs accompanying herself on ukulele, and getting the assembled kids to join in. She then read some children's books, again inviting audience participation.
There were several other vessels docked ahead of Mary's berth. One of them was Cornell, a tug formerly owned by the Lehigh Valley Railroad and now preserved and used for excursions and training.
Your correspondent once took a ride on her and witnessed a rescue.

Although ship's cat Chiclet was named the official host of the party, she wisely remained in the cool of the warehouse adjoining the dock on a very warm afternoon.

Okay, so I have this thing about dolphins.

I've had a soft spot for dolphins since I was seven years old and saw them sporting around the French liner Liberté as my mother and I crossed from England, where my father was then stationed, to visit my grandmother in Pennsylvania. My affection was solidified two years later when, back stateside and in the fourth grade, I read Children of the Sea, by Wilfrid S. Bronson, which told the story of a bottlenose dolphin to whom Bronson gave the generic name Tursiops (the species name is T. truncatus) from his birth in the shallow waters off Florida's Ten Thousand Islands, along the Gulf coast below Naples, through his travels with his mother and the rest of the pod around the Straits of Florida and northward into the Atlantic, with lots of accounts of his encounters with various and sometimes bizarre sea creatures. One of these encounters, with sharks, leaves him injured, and he finds refuge in Nassau harbor, the Bahamas. There he befriends a poor boy named (as I recall) Sam*, who dives for coins tossed into the water by passengers on cruise ships.

As I grew I learned more about dolphins: about Pelorus Jack, who guided boats through tricky waters in New Zealand; of their being said to have saved drowning humans; of the size and complexity of their brains; and of their having what seemed to be a language made of whistles and clicks. Recent research even indicates that they know each other by name.

From Bronson's book I learned that people in the Bahamas called bottlenose dolphins "herring hogs" because of their appetite for fish. As a child, I was horrified when I read an account by Dr. John Oliver La Gorce, then President of the National Geographic Society, of a fishing trip from Nassau in which he and his companions spotted "a kind of large porpoise[**] called a 'herring hog'" which, "because this species destroys many food fish," they harpooned him, hauled him to the boat and "dispatched him."  I was later to learn, through an old issue of National Geographic, that there had been a fishery for bottlenose dolphins on Hatteras Island, North Carolina, in which they were entangled in nets, hauled ashore, and butchered for sacs of oil in their foreheads; the oil was considered ideal for lubricating fine timepieces. (These sacs, I later learned, were essential to the dolphins' ability to echolocate, i.e. to use "sonar," as a means of spotting prey and underwater obstacles.) I was relieved to read that this fishery ended in 1929.

As I grew older and began to focus more on girls than on dolphins, I was happy to know that they had become protected by law, at least from deliberate slaughter. As a young adult, I was troubled to know that hundreds of thousands of dolphins were dying as collateral damage in commercial tuna fishing. I gave up tuna for a while, until the companies began putting "dolphin safe" labels on the cans. (Yes, I trusted.)

So, I went for some years not concerned about the well-being of dolphins, until I learned of the annual mass slaughter of dolphins in a cove near the fishing port of Taiji, Japan. This clip tells the story:


As the video reports, the scale of the killings has been declining in recent years. While this is heartening, a Scottish woman, Shona Lewendon, is leading a campaign to have it brought to a definitive close. Her leverage is Japan's bid for Tokyo as venue for the 2009 summer Olympics. and the International Olympic Committee's requirement that host nations adhere to environmental standards.

 *My memory may be playing tricks with me here. Bronson was a prolific author and illustrator of children's books. Along with Children of the Sea, my elementary school library had three other of his: The Earth for Sam (geology and paleontology); The Sea for Sam (marine biology and oceanography); and The Stars for Sam (astronomy), all of which I checked out frequently. I seem to  recall in the forewords to these books that Bronson identified Sam as a nephew. I still recall that he also called the boy in Children of the Sea Sam.

**The words "dolphin" and "porpoise" are sometimes used interchangeably. Strictly speaking, they are two different types of small cetaceans, the class of strictly aquatic mammals that also includes whales.

New Year's Greetings from Cape Cod

I'd been to Cape Cod once before. In 1988, I was asked to speak at the fall meeting of the Insurance Accounting and Statistical Association in Hyannis in November. It was held in a Holiday Inn that was undergoing off-season renovations, and new carpet was being put down in the hall outside my room, so I was inhaling carpet glue fumes as I put the finishing touches on my speech. My company's CFO and I decided to venture out for dinner one evening, and got caught in the season's first snowstorm. So, when friends invited my wife, daughter, and me to join them for New Year's at their house in Orleans (see photo above), I was skeptical. The drive up was through fog and rain, which inensified my doubts. However, New Year's Day dawned bright and clear, and after breakfast we drove to Nauset Beach, on the Atlantic Ocean side of the Cape Cod Peninsula.

We weren't the only people out enjoying the beach.

Some were enjoying it with gusto.

There were seals with their heads out of water, but too distant to get a good photo.

Here is a very gnarly piece of driftwood.

These are dunes above the beach.

The dunes are a nesting place for threatened seabirds.

Behind the dunes is the Orleans Town Inlet.

On the shore of the Inlet, I found this water dwelling snail and its track. These snails prey on oysters, drilling through their shells to eat them.

A gull paddles across the surface of the Inlet.

High-flying cirrus clouds betoken another change in the weather.

I'm delaying posting my usual New Year's shout-outs until we return home. Happy New Year!

Shark! Where?

HuffPo
Just when you thought it was safe to go back into the water, HuffPo comes out with a piece about a shark that has the ability, like Gollum with his "precious", to make itself invisible. Happy Shark Week.
