Maine Start-up Using Kelp to Fish For Carbon

Posted on by March 1, 2021

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

Posted on by February 28, 2021

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

Posted on by February 27, 2021

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

Posted on by February 26, 2021

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

Posted on by February 25, 2021

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.

Mystery Oil Spill Tars Israel’s Mediterranean Shoreline

Posted on by February 24, 2021

The New York Times reports that a large oil spill from an unknown source has devastated sea life in the Mediterranean and spewed tons of tar across more than 100 miles of coastline from Israel to southern Lebanon in what Israeli officials are calling one of the worst ecological disasters in decades.

Shaul Goldstein, the director of Israel’s nature and parks authority, said the spill would set back three decades of efforts to protect and renew biodiversity along the coastline.

Thomas Slade, Naval Architect & Mast Shipwright

Posted on by February 23, 2021

Thomas Slade, a pioneering naval architect and shipwright, died in 1771, 250 years ago today. While he is most famous for the design and construction of Admiral Horatio Nelson’s Victory, his larger contribution to the Royal Navy and even in Nelson’s victory at Trafalgar itself, can not be overstated.

N.A.M. Rodger wrote of Slade: The ships which [he] designed…were admirably suited to Britain’s strategic requirements…By common consent, Slade was the greatest British naval architect of the century…it was generally agreed (even by themselves) that his successors, though competent designers, never matched his genius.

The Hanging of Captain Nathaniel Gordon of the Slave Ship Erie — February 21, 1862

Posted on by February 12, 2021

On February 21, 1862, Nathaniel Gordon, captain of the slave ship, Erie, was executed by hanging in New York City. Under the Piracy Law of 1820, slave trading was considered to be an act of piracy punishable by death. He was the only slave-trader ever to be tried, convicted, and executed in American history. Captain Gordon, originally from Portland, Maine was 36.  In a detestable trade, Captain Gordan was among the worst. When he was apprehended by the USS Mohican 50 miles off the Congo in 1860, the Erie, a ship of 500 tons, had 897 Africans crammed aboard. Of these, 563 were children. Captain Gordan preferred children because they were smaller and were less able to attempt to take over the ship.

Vaccinations at the USS Juneau Center, Remembering Federal Shipbuilding & Drydock

Posted on by February 20, 2021

Waiting in line for vaccinations at the site of Federal Shipbuilding. Manhattan skyline in the background.

My wife and I recently received the second of two shots of Covid-19 vaccine at a drive-through vaccination state set up at the USS Juneau Center, on the site of the old Federal Shipbuilding & Drydock Company in Kearny, NJ.

We followed a long line of cars snaking around the scattered warehouses until we reached the garage area where the line split into four lanes with multiple vaccination stations inside the garage doors, that opened to allow cars to enter and leave and then closed again to keep out the cold. We were vaccinated through our open car windows. The process was safe, efficient, and almost painless. 

The process was, for me at least, a bit surreal. The long line of cars inching their way around warehouses and past the skeletal remains of a huge fabrication building felt like a cross between waiting for a ride at Disney World and being on the set of a post-apocalyptic zombie movie. I wonder how many of those waiting to be vaccinated knew the history behind the USS Juneau Center or the largely barren industrial space that surrounds it.

“An Apocalypse of Turtles” — Naval Air Station Corpus Christi Rescues Cold-Stunned Turtles

Posted on by February 19, 2021

As bitterly cold weather left millions without power in Texas, the extreme cold has also been a disaster for wildlife, including sea turtles. Thousands of green sea turtles in the water of Laguna Madre off Corpus Christi have become stunned by the cold. The cold-blooded reptiles become immobile and unable to power their fins to warmer, deeper waters, putting them at risk of dying of predation or exposure, according to the National Park Service.

“It was like an apocalypse of turtles littered on the beach,” Will Bellamy, who came across the turtles, told The Washington Post in a phone interview Thursday.

Navy Continues to Battle Covid-19, New Outbreak on USS Theodore Roosevelt

Posted on by February 18, 2021

Recently, three sailors aboard the aircraft carrier USS Theodore Roosevelt have tested positive for the coronavirus, marking the second outbreak at sea on the ship within a year. 

In the spring of last year, the aircraft carrier USS Theodore Roosevelt became the first US Navy ship to suffer a major Covid-19 outbreak. It started small. In early March, after a potential exposure to the virus in a port-call in Da Nang, one sailor tested positive for Covid-19. A few days later, four more tested positive. Soon dozens of sailors had tested positive and the ship was diverted to Guam. By April, almost one-quarter of the 4,865 sailors aboard the ship had tested positive for the virus, and one sailor had died from the disease.

The US Navy has gained considerable experience in managing shipboard Covid 19 infections but the battle against the pandemic continues.

Maersk To Operate First Carbon-Neutral Containership By 2023

Posted on by February 17, 2021

Today, A.P. Moller-Maersk, the largest container ship operator in the world, announced that it would launch the world’s first carbon-neutral cargo liner vessel in 2023 – seven years ahead of its initial 2030 target. They also noted that all future Maersk-owned new buildings will have dual-fuel technology installed, enabling either carbon-neutral operations or operation on standard very low sulfur fuel oil (VLSFO). 

In 2018, the International Maritime Organization (IMO) established targets for the shipping industry “to reduce CO2 emissions…, as an average across international shipping, by at least 40% by 2030, pursuing efforts towards 70% by 2050, compared to 2008.”

At the time, Maersk chose more ambitious goals for its own operations, announcing its intention to reduce its CO2 emissions by 60% by 2020 and to be wholly carbon neutral by 2050.

Admiral Nelson’s Letter Urged Mistress To Give Their Daughter New Smallpox Vaccine

Posted on by February 16, 2021

A recently unearthed letter from Admiral Horatio Nelson to his mistress, Lady Emma Hamilton, written in 1801, reveals Nelson recommending that their six-month-old baby daughter be given the smallpox vaccine developed by Edward Jenner just three years before.

It is difficult to overstate what a scourge smallpox was in previous centuries. The case-fatality rate varied from 20% to 60% and left most survivors with disfiguring scars. The case-fatality rate in infants was even higher, approaching 80% in London … during the late 1800s.

Happy Presidents’ Day – Lincoln’s Improved Camel Patent

Posted on by February 16, 2021

Nantucket Camel Ride

In the United States, today is “Presidents’ Day,”  a national holiday on the third Monday of February, falling between Lincoln’s (February 12th) and Washington’s (February 22) birthdays.  Here is an updated repost of the tale of a patent granted to Abraham Lincoln for a device to lift boats and ships over sandbars.

In the early 1800s, the entrance to the harbor of the great whaling port of Nantucket had shoaled in. Fully loaded whaling ships could not cross the bar and return to the docks beyond Brandt Point. For years the ships anchored offshore and were lightered, the barrels of whale oil loaded into smaller boats that could make it across the bar.

Celebrating Frederick Douglass on Valentine’s Day — “I Will Take to the Water”

Posted on by February 14, 2021

Happy Valentine’s Day! In honor of both the day and Black History Month, an updated repost about Frederick Douglass. But what does Valentine’s Day have to do with Frederick Douglass?  As a slave, Douglass never knew the date of his birth, so he chose to celebrate it every year on February 14th.

Frederick Douglass was born around 1818. From an early age, he developed a close attachment to ships and the sea. His path to freedom led directly through the docks and shipyards of Baltimore, Maryland.

“Colossal” Deepwater Fish Found Off Japan, Named After Sumo Wrestlers

Posted on by February 13, 2021

A recently discovered large predatory fish found in deep water off the coast of Japan is a reminder that we know more about the surface of the Moon or Mars than we do about the deep oceans.

In 2016, marine biologists brought up a strange, large fish from 8,000 feet below the surface in Suruga Bay, on the Pacific coast of Honshū in Shizuoka Prefecture, Japan. The fish was over a meter long and weighed 25 kg. Subsequently, three more fish of the same type were also caught. While large bony fish are not uncommon in shallow water, they are relatively rare in the deep ocean.

On Chinese New Year — A Virtual Prayer to Mazu, Goddess of the Sea

Posted on by February 12, 2021

Today is Chinese New Year when we bid goodbye to the Year of the Rat and say hello to the Year of the Ox. While not directly related to the New Year, it also seems a good time to say a prayer, at least figuratively or perhaps virtually, to the Goddess Mazu, the Taoist and Chinese Buddhist goddess of the sea and protector of sailors, fishermen, and travelers. Mazu is said to be worshipped in over 20 countries by more than 200 million people. Traditionally, one prays to Mazu for peace and safety, both worthwhile goals in this New Year.

Black History Month: Paul Cuffee — African-American Captain, Ship Owner & Shipbuilder

Posted on by February 23, 2023

During Black History Month, it is worthwhile to remember early African-American shipmasters. Who was the first? That is hard to say. Paul Cuffee is a good candidate.  An updated repost.

Paul Cuffee was born on Cuttyhunk Island, MA on January 17, 1759, the seventh of ten children of Kofi or Cuffee Slocum and Ruth Moses. His father, a freed black man, was a member of the Ashanti people of Ghana. His mother was a Native American of the Wampanoag Nation of Martha’s Vineyard. Cuffee Slocum was a skilled carpenter, farmer, and fisherman, who taught himself to read and write. In 1766, Cuffee Slocum was able to purchase a 116-acre farm in Westport, Massachusetts.

Paul Cuffee went to sea at 16 on whalers and merchant ships, where he learned navigation. During the American Revolution, his ship was captured by the British and Cuffee was imprisoned for three months in 1776 in New York. He returned home to Massachusetts and in 1779 built an open boat which he used to run the British blockade, bringing trade goods to Nantucket and ports on the Massachusetts coast.

Sailors on Japanese Submarine Soryu Use Cell Phones to Call For Help After Collision With Bulk Carrier

Posted on by February 10, 2021

Sailors on the Japanese submarine Soryu had to use their cell phones to call for help after the sub surfaced beneath a Chinese bulk carrier and damaged its radio mast, disabling its communications. Three of the submarine’s crew sustained minor injuries in the crash, which occurred on Monday, government officials said. 

From photos provided by Japan’s Maritime Self-Defense Force, the vessel also suffered damage to its diving planes. The bulk carrier, identified as the Hong Kong-registered 93,000 dwt MV Ocean Artemis, was not damaged. Crew on the bulker are reporting not to have felt the impact of the collision.
