The Kelp Forest :: Part III

California, Natural World, Stories, Underwater Life

Central and Northern California kelp forests are bathed by cold, nutrient-laden currents. The waters here are generally not clear but are rich with animal life. Invertebrate displays on the rocks below the kelp forest are some of the most profuse and interesting in the world and it is common to see large schools of rockfish and pelagic jellies hovering among the kelp. Kelp forests here breed some of the world’s hardiest divers, those who manage year-round dry suits, beach entries and surface swims, winter swells and the distinct possibility of meeting great white sharks in murky water just to dive in Macrocystis.

The Kelp Forest :: Part II

California, Natural World, Stories, Underwater Life

It is my spirited opinion, one that I enjoy defending over a beer after a long day on the water, that diving amidst giant kelp is the most magnificent diving in the world. I am fortunate enough to have had some amazing experiences underwater — watching swarms of hammerheads soar overhead, riding the broad back of an accommodating manta, being eyeballed by an inquisitive whale. However, the diving I consider most dear is that found in the splendid kelp forests along the coast and offshore islands of California. Vast beds of giant kelp (Macrocystis pyrifera) line the shore, rising from rocky reefs nearly 100ft deep to reach the surface before spreading out to form a thick floating canopy. Underneath this canopy, the sensation of swimming amid the columns of kelp plants is akin to flying through a terrestrial forest. Corridors between kelp stalks lead to wide openings in the forest in which schools of fish hover. Shafts of light filtered by the canopy above fall across kelp to the reef below. When the current shifts and bends the kelp stalks in a new direction the topology of the forest changes, creating new avenues and rooms to explore.

The Kelp Forest :: Part I

California, Natural World, Stories, Underwater Life

My first experience with seaweed was as a kid combing the shores of Newport Beach where I grew up. After storms my brother and I would find clumps of the brown stuff pushed up the beach. We would pick through them to pop the small bubbles attached to the leaves. If the seaweed was fresh and still had its rootball attached, we would break it apart to reveal a mix of tiny animals: brittle stars, baby octopus, urchins, crabs, little shells and worms. The glimpses of marine life that seaweed brought to our shore triggered a childhood curiosity in the ocean and its inhabitants. Yet it was not until I began diving in kelp that I gained a fuller appreciation of the ocean world.
