Public Awareness for Springs & Caves

During the June 2017 Surigao Exploration, FCD Jake Miranda donated to Barangay Officials several tarpaulins with Do’s and Dont’s for the local community to follow in order to maintain the prisitine condition and the peaceful ambience of their water resource.

The simple reminders were the following:

1. No defecating or urinating.

2. No lifeguard on duty, swim at your own risk. Please supervise children.

3. No jumping or diving from platform, trees or banks.

4. Leave no trash behind, no toxic chemicals.

5. No loud music or noise, no drinking alcohol.

6. No fishing, no campfire.

The recommended measures are in line with a DENR administrative order on the preservation of caves.

NO DEFECATING OR URINATING. Such signs if used in other communities are seen to help lower E. Coli levels and prevent schistosomiasis infection in water-filled caves.

FCD assists local communities in raising awareness among their constituents of the importance of clean and pristine water bodies in inland ecosystems.

The FCD is working on getting more tarpaulins printed for distribution to the local government units that have springs and caves within their borders.

A Successful Cave Clean-Up

After 3 days of hard work which was from July 25-27, 2017, the Clean-Up Team was able to remove 21pcs. of concrete blocks from deep inside the Pawod Underwater Cave System (PUCS).

Additionally, 200 meters of line were replaced and the main chamber was given a new guide line that follows a more systematic path to allow cavers a better view of Doc’s Chamber as the area is called. A new diagram of the lining will be published soon for everyone’s reference.

FCD gives credit to the following team members:

1. FCD Member and UTD’s Regional Manager, Juan Naval for spearheading the project and for sponsoring the cave lines and line markers.

2. UTD caver Jackie Genuino for the underwater support and video documentation of the maintenance work.

3. FCD Secretary and proprietor of Jaime’s Dive Center, Jaime Lapac for all the logistical support required during the 3-day project.

The garbage collection was not fully completed at the sump due to time constraints but the FCD will be making another schedule for the removal of the debris scattered all over the bottom.

All cavers are also encouraged to collect garbage whenever they visit the site. With your assistance, the Pawod Cave can be kept clean and natural looking.

The Filipino Cave Divers dedicate all efforts for the protection and preservation of Pawod Cave to it’s first explorer, the late Dr. Alfonso “Boy” Amores.

Pawod Cave Clean-Up Project

The FCD in cooperation with Jaime’s Dive Center and Unified Team Diving (UTD) Regional Manager, Juan Naval (with UTD caver Jackie Genuino) started today the maintenance project inside the Pawod Underwater Cave System (PUCS) of Mactan Island, Lapu-Lapu City, Cebu.

1. Removal of the concrete blocks placed by a group of divers some years ago. The blocks that weigh 10-15kg each and numbering approximately 20pcs. were placed around the main chamber, at the start of the tunnel and all the way to the deepest point of the area. These were used as line guides by the said group but FCD deems the blocks unnecessary and obtrusive and thus has ascertained that the careful removal of the blocks will return the PUCS to a more natural setting. In addition, it may give visiting cavers a better perception of the place as a cave system that still harbors exploration opportunities.

GOPR7846_1500969051147_high-1200x900

One up, a few more to go.

2. Relining of the chamber and tunnel. Due to age, certain points of the main lines have become frayed and are needing to be replaced for safety purposes. And since the unsightly concrete blocks will all be removed, the lines will be reattached to other points of the cave.

3. Removal of plastics and other garbage inside the cave and in the sump. Due to rain runoffs and from basically lack of care by the community for the area, there is numerous garbage swept into the bottom of the sump, flushed into the cave and lodged inside the cracks in the cave walls and ceiling.

The FCD wishes to remind visiting cave divers to be sensitive to the frailty of the cave and exercise due caution when exploring the site to avoid further damage to its walls and ceilings due to body and air bubbles contact.

It is the hope of the FCD that Pawod Cave may be given its proper protection soon by the Local Government Unit (LGU) of Lapu-Lapu City. The creation of the ordinance for the site’s declaration as a protected area is still ongoing at the LGU level.

Acknowledgement goes to the efforts of Juan Naval and Jackie Genuino for reaffirming the importance of the clean-up and for coming down all the way from Manila to spearhead the project.

REPORT: Search and Recovery in an Underwater Cave in Siargao Island

SIARGAO ISLAND- In the late afternoon of April 29, 2017, the body of a 40 year old male was found deep inside an underwater cave of a spring in Brgy Esperanza, Del Carmen municipality of Siargao island.

The deceased, Mr. Jose Borja, a local farmer, was believed to have suffered a seizure while doing laundry in the Can-agong-agong Spring in Dringcamdors Village. (9° 51.889’N, 126° 1.082’E)

Cave divers Jake Miranda and John Rey Pingkian of Surigao City recovered the body from a crevice inside the cave.

Barangay chairman Fred Galolo said that Borja was reported missing on April 19th and was last seen in the spring attending to his laundry. They immediately conducted a search and suspected that Borja drowned in the spring. Hookah divers using compressor-fed air tried to dive the spring but failed to penetrate beyond the entrance.

Del Carmen Mayor JR Coro requested the assistance of Miranda, a member of the Filipino Cave Divers and a dive supervisor of Emergency Response Diving International, an international dive agency specialized in public safety diving and body recoveries.

The dive team arrived on site at 2 PM, and immediately set up all the gears. The underwater operation commenced at 3:43 PM. There was zero visibility throughout the search and the diver had to grope for the cave walls to avoid getting disoriented.

The dive was made even more challenging because it was a foray into an unexplored cave which was also heavily-silted. The second diver acted as surface tender and standby diver. At 4:08 PM, the body was finally located at a depth of 4 meters during the ascent phase of the dive.

At 4:13 PM, the diver surfaced with the body of Borja which was in an advanced state of decomposition. It was then placed in a body bag away from public view. The whole underwater search took 30 minutes and went as deep as 15 meters. After procedural turnovers using the chain of custody, the area was secured and the cordon was removed. The activity was terminated at 6 pm.

The municipal, barangay government units and local police station provided excellent support at topside which lessened the risk and made the recovery successful without incident. Protocols like cordoning the area, pre and post-briefings, and safety procedures concerning contaminated water were practised throughout the activity.

The volunteer recovery team was well supported by other parties. Shore It Up Foundation of Metro Pacific Group lent Ocean Reef full-face masks and an M105 and GSM DC underwater communications setup, while Ravenworks also lent a Viking HAZMAT drysuit, an OTS full-face mask and a net body bag.

Siargao island, a well-known tourist destination famous for its surfing, is a limestone-rich flatland with numerous springs and waterways in the middle of lush forests and mangroves. Locally known as bito or busay, most of these springs serve as laundry areas. The springs with the purest waters are the main sources of drinking water for the remote villages.

Preserving a Dying Spring

FB_IMG_1488976199398.jpg

The Filipino Cave Divers is proud to be part of a landmark move to preserve a dying spring.

As of March 5, 2017, the blue lagoon area of Enchanted River is closed for swimming. The decision came after a series of scientific studies and multi-partite consultations with the Hinatuan LGU, local tourism stakeholders, Department of Tourism, Department of Environment and Natural Resources and its Environmental Management Bureau, a team from Department of Biology, University of San Carlos, Cebu City, Filipino Cave Divers, and Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ).

In the past, swimmers would intentionally and unintentionally break off rocks from the delicate limestone walls. The rocks descend down to the underwater cave and block the mouth of the spring. As the mouth got smaller, this decreased the optimal flow of freshwater, allowing seawater to come in and destroy the river. As more tourists visited and swam in the blue lagoon, the situation became irreparable to the point that no freshwater was coming out of the spring.

Since the closure of the blue lagoon to swimming, the spring has been restored to its original condition-bluer than blue freshwater has been coming out and forcing salty water back to sea. The unimpeded flow of the freshwater benefits the ecosystem of the river which extends out to Hinatuan bay, the traditional fishing grounds of Hinatuanons.

A new swimming area downstream has been opened just outside the blue lagoon area. This will ensure visitors will still be able to experience the spring’s clean and blue freshwater.

Hinatuan Enchanted River is the most famous tourism site in Mindanao and is gaining more fame around the country and in the world. Help us protect it for the present and future generations to come. It is the only one of its kind in the Philippines.

Biophysical Survey of the Enchanted River: A Scientific Report

Foreword by Ms. Ethel Wagas:

This article is an output from FCD’s project entitled “Rapid Resource Assessment of Four Philippine Underwater Cave Systems”, funded by The Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH (GIZ) under the PAME Project, in partnership with the Department of Biology of the University of San Carlos and the local government unit of Hinatuan, Surigao del Sur.

This was the very first scientific investigation on the flora, fauna and water properties of the Hinatuan Enchanted River Underwater System. The exploration was made possible through the collaboration divers, field scientists and representatives from the local government – with the aim of better understanding the ecosystem of both the underwater cave system and its connecting river. This is also the first scientific article produced by the Filipino Cave Divers published in Annals of Tropical Ecology.

Freshwater cave system in Cebu yields an undescribed species of fish

The recent exploration (Dec.7-8, 2015) to Casili Underwater Cave System in Brgy. Arpili- Balamban, gave the team the opportunity to video document a previously unobserved denizen of the deeper portion of the site.  Captured on video is a  yet-to-be described fish that was spotted at a depth of 32 meters and around 600 meters away from the cave entrance. Length of the specimen is approximately 5 inches long. The team was unable to secure a live sample for study.

Alex Santos, Jaime Lapac and Bernil Gastardo composed the  team. For the successful 2-days of exploration, much appreciation and gratitude goes to the hearty support and kind cooperation of the local council and barangay tanods led by Barangay Captain, Hon. Rhodessa Paulin.
