Giant kelp frequently breaks free from the seafloor and gathers in paddies that drift on the surface, attracting marine life. Cortes Bank is an underwater mountain range that has created a unique habitat of kelp forest and surf grass on the bottom of the ocean, enabling a variety of marine life to thrive in the water above. Places like this are rarely seen yet are vital to the health of our planet. Follow @BrianSkerry for more ocean pictures and stories. #kelp #California #sealion #marineprotectedareas」4月25日 12時00分
