Bioluminescence has always been a fascinating natural phenomenon that never fails to captivate those lucky enough to witness it. The Southern California coast is no stranger to these mesmerizing displays, and recently, a team from UC San Diego’s Scripps Institution of Oceanography had the privilege of observing dolphins swimming through the glowing blue bioluminescent waters.
The footage captured by UCSD photographer Erik Jepsen showcases the enchanting sight of dolphins gracefully gliding through the shimmering waves. This magical occurrence is a result of blooms of the algae Lingulodinium polyedra, also known as “red tides” due to the reddish-brown color they exhibit during the day. However, when agitated by movements in the water, these phytoplankton emit a brilliant blue glow at night, creating a surreal and captivating spectacle.
Photographers and nature enthusiasts alike flock to the shores in hopes of catching a glimpse of this ethereal display. In fact, one photographer stumbled upon glowing sand along Sail Bay in San Diego’s Mission Bay area during a recent red tide event. The vibrant streams of electric blue light lead to awe and wonder, as each wave seems to sparkle and illuminate the darkness of the night.
The duration of these red tide events is unpredictable, with some lasting only several days while others persist for over a month. The ever-changing nature of bioluminescence adds to its mystique and allure, drawing both scientists and curious onlookers to the shores in search of this rare and captivating sight.
The enchanting dance of bioluminescent waters and the graceful presence of dolphins serve as a reminder of the beauty and wonder that nature has to offer. As we continue to explore and uncover the mysteries of the ocean, each encounter with such magical displays leaves us in awe of the world we live in. So, next time you find yourself along the coast of San Diego, keep an eye out for the enchanting glow of bioluminescence – you never know what captivating sights may await you.
