Lobstermen sought for rope survey

BOSTON — The Consortium for Wildlife Bycatch Reduction is investigating whether changes in rope manufacturing over the past several decades have had an impact on the severity of entanglements. As part of this investigation, they would like to learn more about how fishermen choose rope and how changes in rope manufacturing have impacted the way they fish.

The research team at the New England Aquarium has been assessing right whale entanglement interactions for nearly 30 years. This work has shown that right whales frequently encounter rope with 82 percent of the population showing distinct scars from an interaction with rope. The results from an online questionnaire will help determine if there are certain rope characteristics that lead to an entanglement becoming severe, or result in a whale breaking free on its own.

The survey data will be used to help identify practical methods to reduce entanglement risk to whales. Responses will be tabulated and compiled into a report to be shared with industry, state and federal governments, and the general public.

Lobstermen who wish to participate may access the survey online at surveymonkey.com/s/Z6ZQL7R.

America’s first solo, non-stop circumnavigator

BATH — On April 11, 1986, Dodge Morgan, who had chosen to become a resident of Maine, sailed his 60-foot boat American Promise into the harbor of St. George’s, Bermuda, 150 days from the date he had set out from the same port. The event marked the first time that an American had sailed solo around the world nonstop.

Morgan accomplished the feat in 150 days, almost slashing in half the previous record of 292 days, and even besting his optimistic goal of a 220-day voyage.

On Aug. 21, Maine Maritime Museum will commemorate the 25th anniversary of that event and pay tribute to the individual whose dream it was to accomplish it.

Morgan passed away Sept. 14 last year, following complications from cancer.

The tribute will be held at the Portland Company complex on Fore Street in Portland and will begin at 4 p.m. with a screening of “Around Alone,” the documentary film that followed Morgan during his epic journey and was a featured program on the PBS program “Adventure.”

Following the screening, members of the circumnavigation team and some whom Morgan inspired will share reflections of both the man and his voyage.

Morgan’s boat American Promise will be dockside for tours. Tickets are available online at mainemaritimemuseum.org.

Rope work and mackerel plows

SEARSPORT — On Aug. 20 and 21 the Searsport Historical Society will exhibit part of Gordon Stanley’s collection of sailors’ rope work and mackerel plows, knives used in the gutting of the fish.

The rope work was made by sailors during their time onboard ship. Some of the work is very intricate, and includes both utilitarian products and objects made for wives and sweethearts back home.

The knives have carved handles of wood, bone, ivory and other materials. The collection is believed to be the largest of its kind in the world.

The hours of the exhibit are Saturday, Aug. 20 from 10 a.m. to 4 p.m., and Sunday, Aug. 21 from 1 to 4 p.m.

Chasing the North Atlantic Bloom

WEST BOOTHBAY HARBOR — Bigelow Laboratory’s ninth Café Scientifique gathering of the summer will be led by Bigelow research scientist Nicole Poulton, who will highlight her recent investigations of the Northern Hemisphere’s massive spring blooms of phytoplankton — the microscopic, single-celled plants that form the yearly foundation of the food web in the North Atlantic Ocean. Poulton’s talk, titled Sea Truth: Chasing the North Atlantic Bloom, will take place Tuesday, Aug. 23 at 6 p.m. in the Boothbay Harbor Opera House, 86 Townsend Ave. in Boothbay Harbor.

According to the website wordorigins.org, “Scuttlebutt is an early 19th century nautical term for an open cask of water kept on deck for use by the crew. The term comes from scuttle — to cut a hole in — and butt — a large cask. Sailors would gather about the cask and trade stories and gossip, much like modern office workers do at the water cooler or coffee pot. By the turn of the 20th century, American sailors began using the term scuttlebutt to refer to these sea stories and gossip. Eventually the term became associated with any gossip or rumor.”

Send scuttlebutt to Herald Gazette reporter Shlomit Auciello at sauciello@villagesoup.com or call 207-236-8511.
