Join us aboard the Explorer Dive boat for a truly unique diving adventure. .  Located on Santa Cruz Island, it is 1227 feet long (nearly a quarter mile!) and 100 feet wide and the entrance ceiling sits at a staggering 160 feet and is easily large enough to take a 40-foot boat inside. It got its name from the colorful rock types, lichens, and algae that cover the interior walls.  The cave is home to a ton of different marine species.  Since the majority of the cave is protected from the sun, you will get to see marine life species that are generally only viewed during night dives.  The surface is accessible for the majority of the cave although it does get quite narrow and closes off in the back. With that said, this is an advanced trip.  Advanced certification and a healthy logbook are a must.  If you plan on venturing deep into the cave make sure you have the appropriate lights – primary, backup and tank – as it does get quite dark.  This is a “weather permitting” trip. 90% of the time the water is crystal clear and still, but as you all know bad weather and conditions are always a possibility with California diving and there are tons of great dive spots on Santa Cruz.  We will be doing 2 dives at the painted cave and 1 dive in a “secret spot” specifically chosen by Captain Tony for this trip.

An epic day of diving at Catalina on Sunday, August 10th. The conditions continue to be outstanding with 70 degree water and clear visibility to at least 40 feet; it's almost tropical! The leopard sharks, horn sharks, bat rays, rockfish, and many other species were gracing us with their presence at Emerald Bay and Isthmus Reef. The Garibaldi were especially feisty when we happened to get too close to a nest. A little current kicked up when we dropped down on Isthmus, but it created a fun and easy drift dive condition.

It was a beautiful, flat calm ride in the morning out to Catalina Island on the Pacific Star.  We headed to Emerald Bay for 2 dives with the 3rd dive at Isthmus Reef. Conditions were fantastic with water a warm 72 degrees with a thermocline to 66 degrees at around 35 feet.  Fantastic 30' viz with bright sunshine lighting up the kelp forest.  Lots of sightings of leopard sharks, bat rays, horn sharks, an angel shark and the usual kelp critters.  Current picked up at Isthmus Reef where a diver spotted a juvenile Giant Black Sea Bass! Join us next time with Eco Dive Center

- Silent Bubbles sounds like the name of a Ninja Dolphin, but it’s actually an important concept to understand for all divers, especially those concerned with decompression illness. Before the 1960s, it was thought that divers who followed navy dive tables were not at risk of developing DCI.

in 1969, a series of ultrasound studies were conducted on divers who had performed “safe dives”. These doppler studies revealed that even though the divers did not exhibit symptoms of DCI, they most certainly did have detectable bubbles in their bodies. These were dubbed “silent bubbles.” Divers with silent bubbles usually suffer extra fatigue but otherwise seem okay. The danger of silent bubbles lies in divers not realizing they need to de-gas before making multiple dives, which raises the risk of suffering more acute DCI symptoms.

It’s because of silent bubbles that we take the time to do a safety stop for 3 minutes at 15 feet. Safety stops are not strictly necessary for decompression on recreational dives, but are very effective for releasing silent bubbles. Long story short, always make your safety stop if you have the air, but in an emergency situation, skipping a safety stop won’t kill you. Just get to the surface.
