Bomb Cyclone

The Aleutian Chain was rocked by an incredible storm over New Years. The wonderfully named Bomb Cyclone, set a record in Alaska for a low pressure system.

High and low-pressure systems form when air mass and temperature differences between the surface of the Earth, and the upper atmosphere, create vertical currents. In a low pressure system, the air currents flow upward, sucking air away from the earth’s surface like a giant Shop*Vac.

Eareckson Air Force Base on Shemya Island recorded the record low pressure at 924.8 millibars.

A sea buoy off of Amchitka Island, registered a wave at 58.1 feet. Winds at Shemya hit gusts of 83 mph. This was an impressive storm that pummeled the outer islands of the Aleutian Chain. From Atka to Adak, the islands were seeing 40-50 foot waves and hurricane force winds.

St Lawrence Island and the Yukon Delta saw high winds and blizzard conditions when the storm hit Alaska’s mainland.

Unlike a hurricane, which extract heat from the ocean, as they grow in power, a maritime cyclone creates energy by drawing together warm and cold air masses. It’s the energy created when the warm air rises and the cold air sinks, that gives rise to the cyclone.

USS Abner Read


USS Abner Read

The U.S. destroyer, Abner Read, struck a Japanese mine off the coast of Kiska Island on the 18 August 1943 during the Battle of Kiska. The explosion tore off the ship’s stern. There were over 300 men on board the Abner Read that day, many were in their bunks in the stern when the mine blew at approximately 1:50am. 71 sailors died, but 20 were hauled out of the frigid Bering Sea waters.

The crew was able to keep the destroyer afloat. The ship was shored up as best they could, the main compartment was kept water tight, and a homemade rudder was attached. Two U.S. Navy ships then towed the Abner Read to port.

Within months, the Abner Read had its stern repaired, and the destroyer rejoined the war.

In July of this year, a research team funded by NOAA, discovered the Abner Read’s stern off the coast of Kiska Island. It’s general location has been known, and the team of scientists from the Scripps Institution of Oceanography at the University of California San Diego and the University of Delaware used multi beam sonar to locate the wreckage. They then sent a remote operated submersible down to the stern, which was in 290 feet of water.

The stern section measures 75 feet long and 18 feet high, and is now covered in marine life.

Daryl Weathers was a 19 year old seaman on the Abner Read. He is the last known survivor from the destroyer on that August day in 1943. Weathers is 94 now, and lives in Seal Beach, California. When told that the stern section had been found, Weathers expressed surprise saying, “That’s the end of the world up there.”

For its wartime service, the Abner Read received four battle stars from the Pacific Theater. In November of 1944, during the Battle of Leyte Gulf, the Japanese launched a kamikaze attack. A Japanese dive bomber (VAL) made it through the anti aircraft fire, although it had been hit. The bomber was able to drop one of its bombs down the destroyer’s smokestack, blowing up the engine room. The VAL then crashed across the main deck, setting it in flames. The Abner Read sank within hours.
