California

Due to their unique position relative to the eastern Pacific current, or the California Current, the Channel Islands off California’s coast receive an ideal amount of nutrients and water circulation for optimum growth of California giant kelp. This colonial algae forms forests over the rocky reefs and walls surrounding the islands, and act as one of the world’s most productive marine ecosystems.

Cool sunlight slowly crept down from the horizon to the kelp beds off La Jolla in southern California. I took another sip of coffee. Sea lions barked on occasion as small groups of pelicans flew up the coast to start their day.

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.

San Diego’s Wreck Alley is an area with intentionally sunken ships. One of the wrecks divers can find here is the HMCS Yukon, which was a Mackenzie-class destroyer that served in the Royal Canadian Navy (RCN) and later the Canadian Forces. She was named after the Yukon River that runs from British Columbia through the Yukon and into Alaska.

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.
