Update: Betelgeuse Getting Brighter — More Likely Dust Cloud than Supernova

Posted on by March 8, 2020

Betelgeuse, with and without dust cloud

We recently posted about the red giant navigational star Betelgeuse in the constellation Orion, which was observed to be growing significantly dimmer. Not a little dimmer but about 40% dimmer. Some astronomers speculated that the dimming suggested that the star may be close to exploding into a supernova as its core collapses. They say that this could happen anytime within the next 100,000 years, or so, a relatively narrow window in astronomical time, if less so from a merely human perspective.  

Not long after our post, blog reader Kevin commented that the star had begun to brighten again. (Thanks Kevin for the heads-up.) So what is going on? 

As reported by Forbes, a new study suggests that the star is not about to explode, it is just a bit dusty.

Update: Cruise Ship Grand Princess — 21 of 45 Test Positive for Coronavirus

Posted on by March 7, 2020

In a press conference yesterday, Vice President Pence announced that of the 45 people tested on the cruise ship Grand Princess, 21 has been found to be infected with the coronavirus Covid-19. Of the 21, 19 were ship’s crew and two were passengers. The San Francisco bound ship had been held offshore in the Pacific pending the results of the testing.

He said that the ship would be moved to a “non-commercial port” this weekend. “All passengers and crew will be tested for the coronavirus,” Pence said. “Those that need to be quarantined will be quarantined. Those that require additional medical attention will receive it.”

Eurythenes plasticus — Newly Discovered Deep Sea Amphipod Named After Plastic In Its Guts

Posted on by March 6, 2020

British researchers have discovered a new species of amphipod. The team from England’s Newcastle University, led by Dr Alan Jamieson, found the shrimp-like crustacean in the Pacific Ocean’s Mariana Trench between Japan and the Philippines and below the Great Pacific Garbage Patch. The Mariana Trench is the deepest point on Earth’s surface, reaching more than 36,000 feet (11.000 meters) deep.

Despite the great depth at which the animal was discovered, the researchers were alarmed to find that the animal’s stomach contained pieces of polyethylene-terephthalate. Polyethylene-terephthalate, commonly abbreviated PET, is a common plastic resin used in fibers for clothing, in packaging for food and bottles for liquids. They decided to name the animal Eurythenes plasticus to highlight that plastic pollution is now so prevalent that even a new species of amphipod living nearly 7km below sea level had ingested plastic.

Déjà Vu — Cruise Ship Grand Princess Held Offshore For Coronavirus Testing

Posted on by March 5, 2020

Yogi Berra is alleged to have said, “It’s like déjà vu all over again.” News of another cruise ship in limbo over the coronavirus feels that way. 

On February 5th, we posted about the Diamond Princess, a cruise ship that was being held for coronavirus testing and quarantine at Yokohama, Japan, confining roughly 3,700 passengers and crew. Now, almost exactly one month later, the cruise ship, Grand Princess, is being held off San Francisco pending testing of passengers and crew, who have shown the symptoms of the coronavirus. Passengers who were on the previous voyage and remained aboard will also be tested.

The Monitor’s Dahlgren Guns, Frank Butts’ Boots and the Wailing Black Cat

Posted on by March 4, 2020

On New Year’s Eve, 1862, USS Monitor was under tow off Cape Hatteras, North Carolina in a winter storm. The ship was taking on water and in grave danger of sinking. Francis “Frank” Butts, of Providence, R.I., the Monitor‘s helmsman, was bailing water from the ship’s turret which housed two 11″ smoothbore Dahlgren guns.

USS Monitor was an iron-hulled steam-powered warship whose battle with the Confederate ironclad CSS Virginia, ex-Merrimack, had made wooden battleships obsolete in a single afternoon. While the Monitor survived its battle with CSS Virginia, it was losing its battle with the Atlantic winter storm.

Climate Change Causing Faster Winds and Accelerating Currents

Posted on by March 3, 2020

Climate change is affecting the oceans in a wide variety of ways. Oceans are warming and acidifying as temperatures rise and CO2 increases. Sea levels are rising as polar ice caps melt. Recently a study suggests that ocean currents have been accelerating, driven by rising wind speeds.

Scientific American reports that a study published…in Science Advances finds that global ocean circulation has been accelerating since the 1990s. The study examined decades of observations from instruments that monitor the seas’ kinetic energy—a measurement of how fast the water is moving.

Congratulations to Australian Bill Hatfield, 81, the Oldest, Non-Stop, Unassisted Circumnavigator

Posted on by March 2, 2020

Congratulations to Australian Bill Hatfield, who at 81, recently completed a solo, non-stop, unassisted circumnavigation of the globe. His almost nine-month voyage on his 38-foot yacht L’Eau Commotion, was all the more remarkable because he sailed westward against the prevailing winds and currents. He had previously made three unsuccessful attempts but was turned back each time by weather or damage to his boat. 

The previous holder of bragging rights to the title of oldest solo circumnavigate is Jeanne Socrates, who at 77 completed a solo, unassisted circumnavigation.

HMS Erebus Artifacts Provide Glimpse into Franklin Expedition Sailors Lives

Posted on by March 1, 2020

Artifacts recovered during 93 dives by Parks Canada on the wreck of HMS Erebus over three weeks this fall provide a fascinating glimpse into the lives of the officers and sailors on the doomed Franklin Expedition of 1845. More than 350 artifacts have been recovered, including epaulets from a lieutenant’s uniform, ceramic dishes, wine bottles, a hairbrush with strands of human hair, and a pencil case. Sealing wax with the imprint of a fingerprint believed to belong to Edmund Hoar, the captain’s steward was also found.

“We have had the most successful season since the discovery of the wreck,” Marc-André Bernier, manager of Parks Canada’s underwater archeology team, told reporters in a press conference. “The preservation of the objects is quite phenomenal.”

The US Navy’s 7th Fleet Self-Quarantine — No Port Calls for 14 days

Posted on by February 29, 2020


While some ill-advised politicians are referring to the threat from Covid-19, the rapidly spreading coronavirus, as a “hoax,” the US Navy is taking it very seriously. Ships in the 7th Fleet has been ordered to spend at least 14 days at sea between port visits as nations in the region battle outbreaks of the new coronavirus, a Navy official told Stars and Stripes on Friday. The ships are effectively being put into self-quarantine.

“Unprecedented” Number of Blue Whales Observed Off Southern Ocean South Georgia Island

Posted on by February 28, 2020

Mother Nature Network is reporting that a team of scientists led by the British Antarctic Survey (BAS) counted 55 Antarctic blue whales during their 2020 expedition to the sub-Antarctic island of South Georgia — a number they called “unprecedented.” In a previous BAS survey in 2018, only one Antarctic blue whale had been sighted.

In addition to Antarctic blue whales, the team recorded 790 humpback whales during the 21-day survey and estimated that there are now more than 20,000 of them feeding off the island seasonally.

TBT– Frederick Douglass — “I Will Take to the Water”

Posted on by February 27, 2020

Frederick Douglas

An updated repost in honor of Frederick Douglass and Black History Month. 

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.

As a young man, Douglass was sent to work in the shipyards at Fells Point as a caulker and shipwright’s helper when he was around 12 years old. In the shipyard, he learned the first letters of the alphabet — “L” and “S” for larboard and starboard and “F” and “A” for fore and aft, from marks made by the shipwrights on ship’s frames to identify where they were to be placed on a ship under construction.

Archaeologists Discover 200 Ancient Roman Amphorae in Underwater Cave

Posted on by February 26, 2020

Over the years, we have posted about the “world’s oldest beer” and the “world’s oldest champagne” found in shipwrecks dating from the 1700s. Recently, divers have located roughly 200 ancient Roman amphorae, believed to originally have stored wine, in an underwater cave off the coast of Majorca.

The ceramic containers were found in the Fuente de Ses Aiguades cave, which lies in the Bay of Alcudia on the northeastern coast of Majorca, in the Spanish Balearic Islands. Unlike the ancient beer and champagne bottles whose contents were still more or less intact, the amphorae are no longer sealed so whatever they contained, whether wine or oil, has long washed away.

Grays Harbor Historical Seaport’s Hawaiian Chieftain Up For Sale

Posted on by February 25, 2020

For several years now, the Grays Harbor Historical Seaport‘s tall ships, the replica brig Lady Washington and the square topsail ketch Hawaiian Chieftain, have sailed the Pacific Coast offering educational and sail training programs. One highlight of these programs were the “battle-sails” where the two ships maneuvered to fire blanks at each other in mock combat. We recently posted a video of a “battle-sail.”

The “battle-sails,” at least those involving the Hawaiian Chieftain, appear to be coming to an end. Grays Harbor Historical Seaport (GHHS) has announced its intention to sell the Hawaiian Chieftain to focus on the operation of Lady Washington. The decision was precipitated by the discovery of significant problems with the steel in her hull and bowsprit last year by Coast Guard inspectors.

Amazing Video of Humpback Whale Bubble-Net Feeding

Posted on by February 24, 2020

Here is a breathtaking video of humpback whales bubble-net feeding in Alaska shot by the University of Hawaii, Mānoa Marine Mammal Research Program (MMRP). The whales use bubbles to create virtual nets to herd their prey. The video was captured using aerial drones and also by cameras attached by suction cups to the whales to give a whale’s eye view perspective. Simply amazing.

Song For A Sunday — Bob Wright’s Downing’s Oyster Bar

Posted on by February 23, 2020

A follow up to yesterday’s post about Thomas Downing, the free black owner of an upscale oyster house in New York’s financial district prior to the Civil War. While serving New York City’s white financial and political elite upstairs, Downing also ran an Underground Railroad station in his restaurant’s basement, helping runaways escape from slavery. Here is a song by Bob Wright and Harbortown about Downing’s duel enterprises —  Downing’s Oyster Bar.
