Cannons and Anchor from HMS Rose Believed Found in Savannah River

While preparing to dredge the shipping channel in the Savannah River, the U.S. Army Corps of Engineers may have found artifacts from HMS Rose, a 20-gun Royal Navy frigate, dating from the American  Revolutionary War. Archaeologists with the Corps of Engineers discovered an anchor, a section of timber, and three cannons believed to date from the 1700s.

The Rose was scuttled in the river in September 1779, blocking the channel, to prevent the French fleet from aiding American soldiers attempting to capture the city of Savannah. The British held the city until July 11, 1782, when they withdrew on their own accord. After the end of the war, the wreck of the Rose was removed to reopen the channel to navigation.

Albatross, Amazing Flyers, Not So Great at Landing

Yesterday we posted about Wisdom, an albatross who is at least 70 years old, who recently hatched another chick, making it the oldest breeding bird in recorded history. In a comment on the post, Irwin Bryan pointed out a video that has gone viral of an albatross making a less than perfect landing at the Otago’s Royal Albatross Centre nature reserve in New Zealand, which seems like a perfect post for a Monday.

Wisdom, World’s Oldest Breeding Bird at 70, Hatches a New Chick

Photo: John Klavitter/U. S. Fish and Wildlife Service

A Laysan albatross named Wisdom, first identified and banded on Midway Atoll in 1956, has hatched a chick at the age of at least 70. Wisdom, who returns each fall to Midway Atoll National Wildlife Refuge, outlived most of her mates, and raised over 40 chicks. The typical albatross life span is generally estimated to be 40-50 years.

The  United States Geological Survey (USGS) has tracked Wisdom since she was first tagged, and has estimated that Wisdom has flown over 3,000,000 miles (4,800,000 km) since 1956 (approximately 120 times the circumference of the Earth). To accommodate her longevity, the USGS has replaced her tag a total of six times. She and her chick survived the 2011 Tōhoku earthquake and tsunami that killed an estimated 2,000 adult Laysan and black-footed albatrosses, and a much larger number of chicks, at the refuge.

Polish Adventurer, Aleksander Doba, Who Kayaked Across the Atlantic Three Times, Dies at 74

Aleksander Doba died late last month at the summit of Mount Kilimanjaro at the age of 74. He will be best remembered as an irrepressible, record-setting kayaker who paddled across the Atlantic three times while in his 60s and 70s.

Born in 1946, in Swarzęd, Poland, near the city of Poznań, Doba got into kayaking relatively late, at 34.

And it wasn’t until he was 65, in 2010, that he would embark on the first in a series of three journeys across the Atlantic Ocean, earning Doba, a retired engineer, the nickname the “pensioner adventurer”.

On International Women’s Day +1, Honoring Admiral “Amazing Grace” Hopper

One day after the observance of International Women’s Day, there is still time to remember and honor Admiral Grace Hopper. Grace Hopper was a pioneering computer scientist and a United States Navy Rear Admiral. Hopper received a master’s degree and a Ph.D. in mathematics from Yale. She was nicknamed “Amazing Grace” and is often referred to as the “mother of computing.”

In October of 2020, the U.S. Naval Academy officially opened Hopper Hall, the academy’s new center for cybersecurity studies, named in her honor.  The cybersecurity facility is the first building named after a woman at the three main service academies.

Kitefin Shark, World’s Largest Bioluminescent Vertebrate, Photographed Off New Zealand

Researchers have photographed a large bioluminescent shark in deep water off New Zealand. The kitefin shark was a known species of ocean predator but was only recently discovered to be able to glow in the darkness of its deep-ocean environment. The kitefin shark, which can grow to 180cm, is now the largest-known luminous vertebrate in the world, on land or sea.

The researchers also identified two smaller species of shark — the blackbelly lanternshark, and the southern lanternshark that are also bioluminescent.

Good Ship Fata Morgana Hovering Above the Horizon

David Morris was taking a walk along the coast near Falmouth, Cornwall, in the UK, when he saw what looked to be a large tanker hovering in the air above the horizon. He documented what he witnessed with several photographs.  Apparently, Mr. Morris saw a “superior mirage” also known as a Fata Morgana

The BBC quotes meteorologist David Braine said the “superior mirage” occurred because of “special atmospheric conditions that bend light”.

9th Vendee Globe Ends: Ari Huusela Crosses the Finish Line

The 9th sailing of the Vendee Globe Race is over. After 116 days at sea, Ari Huusela sailing Stark has crossed the finish line at Les Sables d’Olonne. While he was the last sailor to complete the race at 25th place, in terms of bragging rights, he is also the first Finnish sailor to finish the race. 

In a larger sense, anyone who succeeds in completing the single-handed non-stop round-the-world race is indeed a winner. As Lydia Mullan writes in Sail Magazine, “In a race this difficult, making it to the finish is a victory in its own right. Though the last skipper to cross the line, Huusela will finish in 25th place of 33 and ahead of giants like Alex Thomson, Sam Davies, and Fabrice Amedeo who were unable to complete the course.

The Shipbreaking Paradox — Persistent Need, Toxic Problem

Marco Polo on the beach at Alang

Every year, on average, close to 1,000 ships are sold for scrap, or in more current language, to be recycled.  Over the past year during the pandemic, there has been a particular surge in the number of older cruise being sent to shipbreaking yards. Many of these cruise ships have been sent to Turkish shipbreakers.  

The BBC reported recently of two UK cruise ships sent instead to Alang, India for scrapping. The problem is that ships sent to scrap yards are considered to be hazardous waste and it is illegal to send them to developing countries from the UK. UK and EU regulations require that ships being recycled be sent to approved shipbreaking facilities that meet environmental and worker safety rules. As of this November, the approved list contains 43 yards, including 34 yards in Europe, 8 yards in Turkey, and 1 yard in the USA.  

There are currently no approved ship recycling yards on the EU list in Asia, where over 90% of the world’s ships are scrapped. Continue reading

Sailing the Schooner Denis Sullivan — A Proud Heritage and Uncertain Future

A short and lovely video from two years ago about sailing from Milwaukee on the three-masted, wooden schooner Denis Sullivan. Like so many other vessels, the schooner’s 2020 sailing season was canceled due to the pandemic and sadly, her future is uncertain.

Spanish Navy’s Juan Sebastián de Elcano Retraces First Circumnavigation

Last Friday, the Spanish Navy training ship Juan Sebastian De Elcano arrived in Guam on its journey to retrace the first circumnavigation of the globe 500 years ago. As reported by Stars and Stripes, the four-masted ship — named for the explorer who finished the voyage after the death of Ferdinand Magellan — was greeted at Naval Base Guam on Friday by Gov. Lou Leon Guerrero, Lt. Gov. Joshua Tenorio, and Rear Adm. John Menoni, commander of Joint Region Marianas, Indo-Pacific Command.  

The ship, built in 1927, is said to be the third-largest tall ship in the world. It was greeted by a flotilla of canoes from seafaring organizations upon its arrival off Oka Point in Tamuning, on its way toward Apra Harbor, on Friday, the Pacific Daily News reported that day.

Maine Start-up Using Kelp to Fish For Carbon

Image: Bjørn Christian Tørrissen

A start-up company in Maine is testing the feasibility of combatting climate change by growing kelp to capture carbon dioxide. Once the kelp is mature, it will sink to the bottom becoming part of the sediment and trapping the carbon for millions of years. The company, Running Tide Technologies is prototyping the concept this winter.

One often hears the recommendation to plant more trees to help reduce climate change. Saltwater plants like mangroves and seagrasses are estimated to take up 20 times more CO2 per acre from the atmosphere than land-based forests. Kelp could potentially capture far more.

First Black Liberty Ship Captain, Hugh Mulzac, Says No To Jim Crow

Hugh Mulzak served as the first Black Liberty ship captain in World War II. When offered the command, he refused to sail with a segregated crew.

Born in 1886 on Union Island in Saint Vincent Grenadines, he went to sea at 21 and served on British, Norwegian, and American sail and steam-powered ships. After studying at the Swansea Nautical College in South Wales, he earned a mate’s license in 1910. He served as a deck officer on four ships during World War I.

In 1918, he became a naturalized US citizen and in 1920 sat for his Master’s license, earning a perfect score on the test. Despite his experience and qualifications, he was generally only able to find work aboard American ships as a messman or cook. Mulzak has been described as “the most over-qualified ship’s cook in maritime history.”

Iceberg Larger Than New York City Calves from Brunt Ice Shelf

A large iceberg about 490 square miles and about 492 feet thick broke off the Brunt Ice Shelf in the Weddell Sea section of Antarctica yesterday. For comparison purposes, the City of New York is 303 square miles, while Manhattan Island is 23 square miles, so the new iceberg is a bit less than twice the size of New York City but more than 20 times the size of Manhattan.

While the new berg is indeed big, it is dwarfed by an iceberg that broke off the Larsen Ice Shelf in 2017, which at its largest was measured at some 2,240 square miles. Until it broke up last month, the massive berg was threatening wildlife on South Georgia Island.

Gulf Stream and Atlantic Ocean Circulation Weakest in Last Millennium

A new study has determined that the vast Atlantic Ocean current circulation system, including the Gulf Stream, is at its weakest in a thousand years. The slowing of the current, the Atlantic meridional overturning circulation (AMOC), could increase sea levels on the American East coast and may result in extreme weather in Western Europe.

The AMOC is driven by two vital components of ocean water: temperature and salt. In the North Atlantic, warm, salty water flows northward off the U.S. coastline on the Gulf Stream and North Atlantic Current, carrying heat from the tropics. But as it reaches the middle latitudes, it cools, and around Greenland, the cooling and the saltiness create enough density that the water begins to sink deep beneath the surface.

The water then swings back southward and travels all the way to the Southern Hemisphere, submerged, where it makes its way to the Antarctic as part of a global system of ocean currents. The entire system is known as the ocean’s thermohaline circulation (“thermo” meaning heat and “haline,” salt), and it plays many critical roles in the climate. It is also referred to as the global ocean conveyor belt, because it redistributes heat worldwide.

Black History Month: Gladys West — Pioneer of GPS Technology

From maps to apps to chartplotters, we all rely on GPS these days, sometimes whether we realize it or not.  Ethan Siegel recently wrote in Forbes: Unbeknownst to most people, however, the science underlying this technology was primarily developed by two people: Albert Einstein, whose theories of special and general relativity both play an important role, and Gladys West, a still-living and largely unheralded Black woman whose scientific contributions enabled us to understand geodesy and the shape of the Earth well enough to make GPS technology possible.

Now, we all know who Albert Einstien was. Gladys West, perhaps not so much. In honor of Black History Month, here is an updated repost about the Black female mathematician whose work for the Navy made a major contribution to the development of the Global Positioning System.
