Notes:

Today I did an internship with a Discover Scuba Diving (DSD) class taught by Kendal, a recent addition to the teaching staff at Island Divers Hawaii from Australia. The class started off with the students watching a video at the Hickam shop while I assisted Kendal with getting the student’s gear ready. After the video was finished we headed over to the pool to teach the students mask clearing, equalization, and regulator recovery skills.

Most of the students picked up on the skills quickly, however we had to work with one for quite a while on the regulator recovery skill. Every time she would take the regulator out of her mouth and start to recover it she would panic and stand up in the pool. After working with her for about an hour in the pool we were finally ready to head over to the Hawaii Kai shop to meet the boat for the next part of the class.

Once on the boat we headed out to Koko Craters for the first dive of the day. This morning the visibility was about 15 feet so we were a bit apprehensive about how the dive would go. Thankfully the visibility at Koko Craters has improved today after the high tide came in from about 15′ to about 40-50′.

At the surface as we were about to descend the student that was having so much difficulty with the regulator recovery skills started to panic and did not want to go down. As Kendal guided the other students down the descent line I had her turn over onto her back with her BCD fully inflated and talked to her to get her to relax while I towed her back to the boat. Matt, the owner of Island Divers Hawaii was Captaining the Sea Fox today so he said he would work with her on the surface at the swim step of the boat so that I could catch back up to our students.

Once we were all at the bottom we began a tour of the area showing them the sea life that we typically find here which included a large school of Sergeant Major fish, moray eels, and nudibranchs. We also saw a cloud of thousands of Sea Hares floating past in the current. one of the Sergeant Majors took particular attention to one of the students who was too close to his eggs and started pecking him over and over again on the top of his head. It looked like a wood pecker searching for a meal. I started laughing so hard I almost lost my regulator as he fought off the pesky fish.

Another student lost part of his weights and it we had to catch him before he floated up to the surface and replace his weights. A few minutes later he had a similar problem when he got too high and once again he floated to the surface while I fought with him to keep him down. It finally took both me and Kendal to push him back down until his wetsuit compressed enough that he could stay down with the rest of the group. He was a little bit underweighted so we gave him a couple extra pounds of weight and he was able to continue the dive.

Notes:

Did a Solo Kayak Dive today since the dive barge was not going out so that I could get some more measurements and compass headings so that I could complete my Mapping Project for the Divemaster course.

The south swell is really making diving off the south coast difficult this week. I got rolled 3 times on my way out to the dive site. Luckily once I was past the surf zone and out there it was much calmer. Unfortunately the visibility sucked which made it harder to work on my map.

Divemaster Mapping Project

As part of my PADI Divemaster training I am required to create a map of a dive site to teach me underwater mapping and reinforce the underwater navigation skills that I learned in the Underwater Navigator Specialty course that I took last month.

For this task I was allowed to choose Koko Craters, a popular dive site off the South East coast of Oahu. Because I dive this site very often, and had already started a rudimentary map of the location in the Underwater Navigator Specialty dives it would save me some time.

Normally the mapping project is done by a group of Divemaster Candidates (DMC’s) who collaborate on a finished map. Since I am doing this mapping project alone I would have to do everything myself, which would mean multiple dives at the location to get measurements, compass headings, etc.

Unfortunately we have been getting hit with a south swell for the past couple weeks that has made diving on the south shores almost impossible. Most of the dive boats have cancelled their dives and everyone is shore diving up at Sharks Cove for the past two weeks. In order to work on my map today I was forced to do a solo kayak dive in very rough waters.

I ended up getting rolled 4 times today while trying to get out to the site. Once I was offshore out at the site the seas were much calmer and I was able to get some diving done. Unfortunately the visibility was very poor for this location, normally we have around 100′ visibility at Koko Craters, but because of the south swell today it was only 10 to 15 feet, which made working on my map very difficult. There was also a strong current which also added to my challenge, luckily I had strapped one of my DPV’s to my kayak in anticipation of the strong currents and surge. Using the DPV I was able to overcome the current and get some work done on my map.

Here is the map I made of the Koko Craters Dive Site. Hopefully it will be good enough to pass and I can get signed off for this project. I don’t see how I can make it much better.

Notes:

This was the second dive for the Underwater Navigator Specialty course.

On this dive I had to use a compass and locate objects on predetermined headings that were given to me counting kick cycles between the objects, while mapping the area and objects that I found. At the last object I had to use reciprocal headings from each object to find our way back to the boat
