What you are seeing now when you dive the southern Channel Islands, and by that I mean San Clemente, Santa Catalina, San Nicholas and Santa Barbara is not our typical regime. The southern island marine ecosystems have been devastated by the combined wrath of long-term sea water heating and what is now regarded as the greatest El Nino on record. Scientists at Scripps have confirmed a continued rise on ocean temps over the last decade. We had a mini El Nino in 92-93 prior to the mother of all El Ninos 97-98. Previous to this was the 1983 El Nino which was the “Mother of All” prior to the 97-98 ENSO (“El Nino Southern Oscillation”). We at the California Conservancy Divers have ringed Catalina Island with thermographs since 1992 and have the last two events on record as far as Catalina goes. The combined assault of warm water on our kelp forests has devastated our nearshore resources. As I have been diving SoCal for over 30 years I have a historic perspective that includes plenty of diving prior to 1983. Prior to then the lee side of Catalina was home to a fringing kelp forest similar to the one on the lee of San Clemente. Since 1983, that kelp has been in decline and completely disappeared in 1983 and 1997-98. After the 1983 ENSO the kelp never recovered its former range or vitality. Santa Barbara Island was surrounded by an extensive forest. For years it was virtually impossible to travel by boat between Webster Point and Arch Reef which lies 1/2 mile offshore, the kelp canopy was just too thick. Like Catalina, SBI never rebounded from the 1983 event and since then, the purple urchin hordes have turned most of the island into a urchin barren devoid of kelp. (I wonder if the harvest of all the Red Urchins (S. franciscanis), had anything to do with the Purple Urchin (S. purpuratus) horde we now find in many of our southern forests? The 1997-98 ENSO warmed water so long and so deep that virtually all of our giant kelp disappeared. Giant Kelp dies when water temps rise above 68 degrees F. When the kelp died everything that lived in those forests suffered. Where is a Giant Kelp fish to go when there is no kelp? Ditto for the Kelp Crabs and dozens of other vertebrates and invertebrates that live in or use the forests for food or shelter. When the kelp was gone all of our site-attached reef fishes had no cover. They are not migratory such as the Yellowtail or Bonita and had nowhere to run. Virtually all of our large male Sheephead are gone, shot by recreational divers. The remaining population is being strip-mined by the fastest growing fishery in California, the live fish fishery catering to Oriental retailers and restaurants. Ditto for our Moray Eels which do not even breed in these waters according to most scientists. There are a host of other horror stories but that is the bad news. The good news is that our kelp will recover to a great extent. It already started this year and was put on hold when summer waters warmed. Within 1-2 years the kelp beds will recover to some extent but the critters that live there will be long in recovering their former populations. Give us 5 or 6 years. Meanwhile, if you want to dive in SoCal there are some interesting side benefits. For once, you can see the reef in all its glory without the kelp in the way. I have found a lot of caves that were not visible before. That makes for some interesting viewing and a perspective that was not available when visibility was limited by kelp. Lobster season starts this next Friday night and all indications are for another fine year. Last year was a banner year for the divers and commercial lobster trappers. This year looks like a repeat and we sportdivers get a 4 day head start before the commercials are allowed to bait their traps. If you really want to dive SoCal in all its glory the best bet is to dive the northern Channel islands, especially Santa Rosa and San Miguel. Miguel has recovered much faster than the other islands and appears lush when compared to the other southern islands. We will see about the long term but I would hate to see our southern Channel Islands reduced to the level of despair that you will see if you dive the Pt. Loma Kelp beds in San Diego or the Coronado Islands in Mexico. If the warm water continues and we do nothing to stop the unregulated strip-mining of our forests by commercial interests it is quite likely that SoCal will start looking like Pt. Loma and the Coronados. Then, if we want to dive in the kelp like it used to be we will have to travel to San Miguel or Monterey to have it like it was. I hope the warming does not increase and you will be able to enjoy all the fine diving in the south I have been writing about all these years some day soon.
