2020 Long Beach Scuba Show Cancelled

We considered moving the 2020 show to later in the year, but ultimately decided that postponing the show still held too much uncertainty. The wellbeing of everyone under our roof is our primary concern, and there's no way to responsibly hold an event of this size and with people from around the world for the foreseeable future.

If you have already purchased tickets for the 2020 Scuba Show, you have two options. Please email us to let us know your preference:

Northern California: A Dive Off the American Wild West Coast

Warm rinse water sloshed in the jug as my car hugged a sharp turn on California’s Pacific Coast Highway. I looked left at the mighty Pacific Ocean, the cliffs tumbling to the sea dotted by rugged pinnacles, stretching farther up the coast than the jam band solo currently playing out of the car speakers. Deep blue, favorable conditions all week, minimal swell, no-wind forecast—only unpredictable visibility could affect the diving today.

Southern California's Market Squid Run

Most years, Southern California on the US west coast is the site of a special marine life aggregation, treating locals to one of the most unique dives in the world. Hundreds of thousands of market squid (Doryteuthis opalescens) swim into recreational dive depths to mate and lay an expansive canvas of egg baskets (collections of eggs) across the sandy substrate.

U.S. Navy found a tug that was lost for nearly a century

When it left San Francisco on March 25, 1921, Conestoga was en route to Tutuila, American Samoa via Pearl Harbor, Hawaii. When Conestoga failed to reach Hawaii by its anticipated arrival date the Navy mounted a massive air and sea search around the Hawaiian Islands, the tug's destination. Unable to locate the ship or wreckage, the Navy declared Conestoga and its crew lost on June 30, 1921, the last U.S. Navy ship to be lost in peacetime without a trace.

WW2 U.S. aircraft carrier found off California almost intact

NOAA, working with private industry partners and the U.S. Navy, has confirmed the location and condition of the USS Independence (CVL-22), the lead ship of its class of light aircraft carriers that were critical during the American naval offensive in the Pacific during World War II.

Resting in 2,600 feet of water off California's Farallon Islands, the carrier is "amazingly intact," said NOAA scientists, with its hull and flight deck clearly visible, with what appears to be a plane in the carrier's hangar bay.

The new species of white coral is most likely closely related to gorgonian corals.

New coral discovered off California

It was the first thorough exploration of the cold, oxygen-rich waters north of Bodega Head, a small promontory that lies along the California's Sonoma coast just 70 miles north of San Francisco. Submarine canyons, such as Bodega Canyon, extend from the continental shelf to the deep sea – making their exploration a difficult but worthwhile endeavour. The canyons are important because they act as a refuge for important species of fish and provide a habitat for sensitive species of deep-water corals and sponges.

Ships and blue whales in conflict off California

A new study in the journal Plos One has revealed blue whales assemble for long periods in the busy shipping lanes off California, raising concerns about collisions between vessels and the endangered cetaceans.

“It’s an unhappy coincidence,” said study leader Ladd Irvine, a marine mammal ecologist at Oregon State University. “The blue whales need to find the densest food supply. There’s a limited number of those dense places, and it seems as though two of the main regular spots are crossed by the shipping lanes.”
