Cortez Banks: An Underwater Oasis Unparalleled

Nestled approximately 100 miles southwest of San Diego, California, lies Cortez Banks, a profound and mesmerizing underwater ecosystem teeming with unparalleled biodiversity that serves as a beacon of wonder and intrigue for explorers, conservationists, and marine enthusiasts alike.

This marine sanctuary, encompassing approximately 5,000 acres, is renowned for its towering granite pinnacles, formed eons ago by subducted plates beneath the Pacific Ocean. These majestic formations rise from depths of up to 150 meters, creating a captivating underwater landscape that hosts a kaleidoscope of marine life.

Unveiling the Treasures of Cortez Banks

The sanctuary is home to an astonishing array of marine species, including:

• **Over 1,000 species of fish, including giant sea basses, cowcod, and cabezon
• **At least 25 species of marine mammals, such as blue whales, gray whales, and Pacific white-sided dolphins
• **Numerous species of seabirds, including Brandt's cormorants, red-necked phalaropes, and Heermann's gulls
• **A diverse array of invertebrates, including giant sea stars, jellyfish, and polychaetes

The sheer abundance and diversity of marine life at Cortez Banks is attributed to the area's unique combination of nutrient-rich waters, complex topography, and proximity to the nutrient-rich California Current. These factors create an optimal environment for primary productivity, fueling the growth of algae and phytoplankton, which in turn supports the entire marine ecosystem.
