Question of the Day:

What kind of crab makes its home in an abandoned snail shell?

Answer to yesterday’s question: Lines- a word used on a ship meaning ropes; Bosun- a very old word derived from “Boat Swain”- meaning the lead fisherman; Steam- the distance to be traveled on a ship from one destination to the next; Swell- wave action –when the action is greater, the difference between the tip of the wave and the trough represents the swell.

Science and Technology Log 

In the past few days, pods of humpback whales have been sighted near our ship.  I grab my binoculars and watch their show.  They are very acrobatic whales, breaching (jumping above the water), slapping their flippers and lobtailing—meaning they dive below the surface leaving only their large tail fluke showing as they wave it in the air.  If you are lucky enough to get close to a humpback whale, you might be able to see the distinctive markings on the underside of their flukes.  These markings are used to identify individual whales. It is hard to imagine the immense size of this mammal as they reach from 36 to 52 feet in length and weigh up to 40 tons

Humpbacks can be found worldwide and in the winter they migrate south to the Caribbean. Their summer feeding grounds are the Gulf of Maine to Iceland.  Humpbacks were commercially fished almost to the brink of extinction in the 1800’s as whaling ships plied their trade all along the Atlantic coastline, making many fisherman and coastal communities very wealthy. Once they were listed on the endangered species list in 1966 it protected them from commercial harvest.  Their numbers have recovered and it is estimated that 8000-10,000 live and feed in the waters of the North Atlantic.  Seeing these whales is a truly special experience

Personal Log– a poem for humpbacks

On dark waters
You rise
And reach for the sky
Your fluke
Like a signature
Tells all who are near
This is my playground
Too I have returned from the
Brink of extinction.
Atlantic waters
Give me life
Help them remember
I could have been
A ghostly memory
Of times past.
Now, I inspire awe and hope
For the future.
