At Expedition 3, the team of FCD's Bernil and Doc and guest, Lou discovered the blockage of all accesses to Mayor's Chamber by what is now determined as mounds of coarsely granular limestone. A cave-in deep in the area of Mayor's Chamber was suspected. Dive #2 of Expedition 5 was done solely to look for … Continue reading REDESIGN OF HINATUAN’S ENCHANTED RIVER UNDERWATER CAVE SYSTEM – A NATURAL CAVE IN?
NATURE’S REDESIGN OF ENCHANTED RIVER UNDERWATER CAVE SYSTEM
MAD Cavers had the grand design of intensive exploration of Hinatuan's Enchanted River Underwater Cave System (HERUC) at Expedition 3 on June 11-14, 2011. However, the team met an unpleasant surprise - all entrances to Mayor's Chamber were blocked by mounds of either sand or limestone. A couple of theories were entertained as to the … Continue reading NATURE’S REDESIGN OF ENCHANTED RIVER UNDERWATER CAVE SYSTEM
CAVE DIVING PROPULSION TECHNIQUES
http://www.youtube.com/watch?v=-ld4chqQl_8 The two underwater propulsion techniques used in cave diving are the modified frog kick and the modified flutter kick. Technically, these are achieved by bending the knees at 90 degrees with the body in horizontal trim. These techniques are solely intended to avoid the fin wash from hitting the silty bottom of most caves. … Continue reading CAVE DIVING PROPULSION TECHNIQUES
OUT OF CASILI
http://www.youtube.com/watch?v=wqkAevcEuU0 When we first picked up Casili on the net, all we had to work with are a couple of youtube videos. I remember very well the one that really intrigued me. Going to the spring, you drive on the riverbed part of the way. That we did.

Multi-tank capacity of Hollis SMS 100 (R)
Multi-tank capacity of Hollis SMS 100 (R) Owing to certain characteristics of underwater caves, proficiency in sidemount diving is emerging as a necessary skill. Of particular importance is multi-tank carrying especially in long complicated dives. The last FCD expedition (VI) of Casili Underwater Cave required 4 bottom tanks.
HOW ARE SEA CAVES FORMED?
Mactan remains a popular dive destination despite massive coral reef destruction. Human activities impact, i.e. dynamite and cyanide fishing, coral harvesting, gleaning, boat hull and push stick (tukon), pollution from Mactan Channel, scuba and hookah spearfishing, and Koreans have reduced the Mactan reefs to a tiny fraction of what they were decades ago. This has … Continue reading HOW ARE SEA CAVES FORMED?
PAWOD – A JEWEL IN OUR MIDST
