These surveys were conducted between and As Point Conception forms a transition zone between two opposing currents and habitats, climate change poses a greater threat. As the climate warms, it is likely that the transition zones between the currents will move north causing habitat change at Point Conception. Another threat is the extensive shellfish collecting that occurs in this area.
Point Conception forms a transition zone between climate and habitat of the north and south. North of Point Conception is characterized by west facing beaches, storms and high winds, rocky shores and higher diversity of macrophytes.
Whereas south of Point Conception there are sandy shore beaches, relatively calm waters and south facing beaches. In , the lighthouse was moved to a lower elevation of feet 41 m above sea level because severe fog was less likely to obscure the light, In May , a fourth-order Fresnel lens was installed.
In , the station was electrified and the oil lamps were removed. The light station was automated in , ending years of manned operations. The weather at Point Conception is often windy, especially in the winter when winds are predominantly from the southeast through the Santa Barbara Channel.
These gale-force winds were experienced by Cabrillo in and well documented by Richard Henry Dana in on Pilgrim , a sailing brig of The point is also known for unusual waves even in calm weather.
On November 4, , the Channel Islands National Marine Sanctuary research vessel Ballena of 56 feet 17 m overall length, capsized in a rogue wave north of Point Conception. The vessel was working for the U.
Geological Survey and engaged in a routine side-scan sonar survey of the seafloor along the foot 10 m depth contour approximately 0. Guy Cochrane, and assistant Mike Boyle. The weather was fair, with clear skies and swells of 5 to 7 feet 1. My pay has not been forthcoming in over four months. In , the cistern received a new floor and plaster coating, after an earthquake rendered it incapable of holding water. In , a first class, steam fog signal was installed on a large flat area, over feet down the bluff from the lighthouse, to replace an earlier fog bell.
The necessary water for the twelve-inch steam whistle was obtained from a nearby spring and by collecting rainwater and storing it in a cistern. In May , a fourth-order Fresnel lens was transported to the point where it was used in the new tower, while the first-order, Henry-Lepaute lens was disassembled in the old tower.
The fourth-order lens was then displayed from a temporary platform atop the old lighthouse, until the first-order lens was installed in the new tower and exhibited for the first time on June 20, With its tower removed, the original lighthouse, which had to have stabilizing iron tie rods run through it, received a two-room, wooden addition and continued to serve as a dwelling for several more years.

The spacious duplex, with six rooms and a bath for each of the occupying keepers, was completed in at the top of the step staircase that led down to the bluff top.
Charlie Hellwig, a grizzled, one-eyed, civilian lighthouse keeper, was in charge of Point Conception Lighthouse in when it was finally converted to electricity. In the 10 years I have been here we been using kerosene. The light station was automated in Jeanette Miller lived in the duplex when her husband was stationed at Point Conception in the early s and has fond memories of life at the remote outpost. Originally, a pound weight, which remains suspended in the lighthouse, was cranked up every four hours to provide the energy to rotate the lens.
That system of gears and pulleys was replaced by a motor, when electricity reached the station. Sadly, due to the expense of repairs necessary to keep the Fresnel lens revolving, a modern beacon is now used at the lighthouse. The lighthouse has always been an isolated place, evoking strong emotions in its caretakers. Loneliness comes down like a shade, and the light goes on.
The following is his description of the unique feeling Point Conception produced in him. The eerie sound of the fog horn and crashing waves against the cliff and the often foggy days gave the place a ghostly feeling.
Of course no lighthouse worth its salt would be without a ghost story or two, and Point Conception had its stories too. I chose to heed the stories, given the overall feeling that the area gave out. On one occasion we had to replace the chimes on the light. These are brass wheels that the base of the light rotates on.
Over time they wear and need to be replaced. It entails jacking up the base of the light, removing the old wheels and installing new ones. It is also where the coastline forms a near right angle, tending south-north to the north of the point and then west-east on towards Santa Barbara. This is the start of one of the longest sections of west-east coastlines along the entire eastern Pacific.
The Spanish explorers of the sixteenth century first documented the difficult sailing conditions here caused by a turbulent confluence of winds and currents. It is for this reason that the light at Point Conception was one of the first built in California. First, it was moved off the top of the bluff, down to a small mesa, closer to the ocean.
