The Akron at Camp Kearny — the day the airship took her ground crew with her.

On May 11, 1932 the Navy's giant airship USS Akron tried to land at Camp Kearny on the mesa above San Diego. Lightened by the sun and spent fuel, she rose with sailors from the training station still holding the lines. Two fell to their deaths; a third hung on for an hour before he was hauled aboard.

The San Carlos and San Antonio — the scurvy voyage that founded San Diego.

In 1769 two Spanish supply ships reached San Diego Bay, the San Antonio on April 11 and the San Carlos on April 29 after 110 days. Scurvy had wrecked both crews; the San Carlos lost nearly all of her sailors. The survivors' sailcloth hospital on the beach became the start of a city.

The Navy's dolphins — the Point Loma program that sent sea mammals to war.

The Filipino stewards — the sailors who built a community in National City.

From 1901 the Navy recruited Filipinos, and for decades it allowed them to serve only as stewards. The rule ended in 1971. Many who served settled near the 32nd Street base, and San Diego County became home to one of the largest Filipino American communities in the country.

Walter Munk and the surf forecast that went ashore on D-Day.

Scripps oceanographers Walter Munk and Harald Sverdrup built the first practical method for forecasting surf, first for the North Africa landings in 1942. The weather officers they trained in La Jolla called Normandy's surf 'high but manageable.' Munk was born on this day in 1917.

HMCS Yukon — the Canadian warship that sank a day early off Mission Beach.

The retired destroyer escort was bought by the San Diego Oceans Foundation to become an artificial reef. She was meant to go down in front of a spectator fleet on July 15, 2000. A swell flooded her the day before, and she now lies on her side in about 100 feet of water in Wreck Alley.

The Pork Chop Express — San Diego's tuna clippers go to war.

Mystic and Avalon — the rescue submarines that waited at North Island.

San Diego's Japanese fishermen — the men who built the tuna fleet, and lost it.

Japanese immigrants brought pole fishing and long-range boats to San Diego; by 1918 they made up about half the city's fishing crews. After Pearl Harbor community leaders were arrested and boats like the clipper Prospect were seized, and on April 7, 1942 about 1,150 San Diegans of Japanese descent were put on a train to Santa Anita.

The Lelia Byrd — the day Fort Guijarros fired on an American ship.

In March 1803 the Boston brig Lelia Byrd was caught smuggling sea otter pelts in San Diego Bay. Her crew locked up the Spanish guards and ran for the harbor mouth under the guns of Ballast Point. The fort fired; the brig fired back. Nobody died, and she got away.

SS Normandie — the greatest liner ever built, burned at her own pier.

The fastest ship in the Atlantic was being converted to a troopship when a welder's torch ignited a bale of kapok life preservers on February 9, 1942. She capsized in New York Harbor from the weight of firefighting water. The Navy had spent four months converting her.

Joshua Slocum and Spray — the first solo circumnavigation.

Between 1895 and 1898, Joshua Slocum sailed a 36-foot sloop alone around the world. He was 51 years old. He rebuilt the boat himself from a rotting hull. He is the reason single-handed offshore sailing exists as a sport.

USS San Diego LPD-22 — the namesake comes home.

Old Ironsides earns her name — Constitution against Guerriere.

In thirty-five minutes of August 1812, the American frigate dismasted a Royal Navy veteran and watched British shot bounce off her live-oak hull. A sailor shouted that her sides were made of iron. They weren't. They were better.

Rum row off Point Loma — Prohibition's thirsty navy.

Canadian schooners anchored beyond the three-mile limit with holds full of whisky while fast launches ran the gauntlet into Mission Bay at night. The Coast Guard's San Diego flotilla fought a shooting war most cities never heard about.

About The Pulse

One entry every day, posted at sunrise — drawn weighted but unpredictable from the full history of seafaring. Some days you will read about Carthaginian quinqueremes or the Hanseatic League. Some days about kraken sightings and ghost ships. Some days about the propulsion plant of a Virginia-class submarine. The point is the breadth, and the through-line: every line of stone, wood, iron, steel, and silicon that humans have ever shaped to move on water. San Diego is where the modern chapters of that story are being written, and where this archive is being kept.
