Jason and I decided to go diving at Kelvin Grove as we'd not been out there for a long time. The day started out extremely rainy and crappy. However, when we got out to Kelvin, the sun came out and it was a different day.
We dove the right side of Kelvin, and for the second dive, stayed in the center and did some skills.
After the dive, we met one of Jason's co-workers, and he invited us up to his house, which was just up the road. We took him up on his offer, but when we got there, we found that he was taking a nap with his grandson. His wife invited us in anyway, and gave us some tea and cookies. We had a good chat on the political situation of the residents of Lion's Bay and divers. We had never heard the side of the story from a Lion's Bay resident. She described buses coming up loaded with divers, and taking over the entire area. I found it very interesting hearing that side of the story. I knew all my dive friends would not be in the problem category, but had no idea that larger groups had caused such problems for good divers. It looked like those days were over, and that things had calmed down. Which was very good, because it was a very nice dive site.
I had some video from our practice here.

Whytecliff Park 09/09/2011
Jim and I went out again for another skill dive at Whytecliff.
It was the first time I got to try out my new dive vehicle, a Ford Ranger. It worked out great!
We practiced our ascent, and we surfaced a bit farther down the Cut near the day marker. It took a bit of time to swim back in, but it wasn't bad. I always had problems picking the Cut exit point!
Again, doing skills at night added extra challenge.

Whytecliff Park 26/08/2011
Jim and I went out to Whytecliff for a quick night dive and to get some practice for our planned upcoming Tech 1 class.
It was a beautiful evening. It was the first time me and Jim were out for practice. Silly me, I didn't exchange all contact details with Jim, and there was a mixup in the location he would meet me. I didn't give him quite the correct address. Whoops!
We got going quite a bit later, but decided to go ahead anyway. It was a bit hot, but the tide was good and we had a nice dive at the Cut.
It was very very dark in the water. We did some skill practice, and it was much more challenging in the dark with less visual references.
All in all, it was a great deal of fun.

Nanaimo Wrecks and Tyee Beach 23/07/2011
Jason Kolba, Jim Dixon and I decided to meet up to do the Nanaimo wrecks. If I recall properly, Dan McKay my Fundamentals instructor was also along, with a bunch of other GUE divers. It was a nice surprise! Guy Shockey was along too. A few of them had scooters along, and during the dives it was pretty neat to see them flying about.
The day was very nice, sunny but a bit rough. We did the Saskatchewan first, then the Cape Breton. Both dives were great, as always.
After going out on the Sea Dragon for those dives, we decided to do one more dive that day from shore. Jim had to back out on the dive, but Jason and I decided to try Tyee Beach. I had done Tyee before, and it had quite a few interesting rocks.
This time around, we went to the left instead of to the right of the entry. Visibility wasn't the greatest, but we followed some pretty interesting walls and rock formations out then back. On the way back, we did a valve drill. My valve drill didn't go the greatest!
Overall, a great day of diving...

Vancouver Island 25-26/06/2011
I had such a great time in Comox that I jumped at the chance to get out to the Island with Todd and crew again. We brought the scooters along too. I rented a Fiat 500 that got lovingly nick-named the "Firt" because Kat read the label wrong. I was afraid I'd not fit everything into the car when I picked it up. But it worked very well. I could have probably fit one more into the car too!
We met at Willis Point for our first dive. I teamed up with Laudhi, who was having his last cold-water dive before moving to warm-water. He also had the reputation as a person who did not seem to breath. They were right. I was on double 130's and he was on a single steel 100. At the end of 50 minutes, and an average depth of 60 feet, he had not even used up half his cylinder. Willis was always a good dive, and this time didn't disappoint.
After Willis, we went to McKenzie Bite. I'd never dove this before, and we took out the scooters. One funny thing was the small sunken boat. Someone had tied a fake skeleton to the mast. When we went past the boat, I didn't even see the skeleton at all!
We stayed at the Robin Hood Inn in Victoria for the night. The next day, we got as many scooters as we could to do a dive at the Ogden Point Break Water. I dove with Alan Wong and Vince janelle. Visibiity wasn't good, maybe 10 feet. The breakwater must have been a great dive if the vis was better. All in all it was still pretty neat. It was a very hot day, and hauling scooters and doubles down to the beach almost caused me to overheat.
A lot of fun!

Comox and Nanaimo 04/06/2011
Vince Janelle told me about a trip to Comox with Todd Powell and a bunch more of the UTD dive crowd. Eric, Gary, Kat, and Arlene were good to meet finally. We stayed overnight in Comox, and went on the Ata-tude dive boat with Captain Bill.
It was a perfect day, and the first dive was on Vivian Island. I remember Vince and I covered a great deal of distance during the dive.
After lunch on the mainland at Lund at an amazing sandwich joint, we did the SS Capilano. It was an amazing dive. The descent down to the wreck was magical. The white plumose anemones ringed the wreck like a ghostly white halo.
Here is a compilation video clip. Todd and crew were doing a tech dive on the Vivian Island wall. It was neat to look down and see them below!
On the next day, we did Madrona Point on the way home. We found quite a nice octopus and set of wolf eels in the rocks. I tried to see if the wolf eels were interested in boiled eggs. They were not!

Topline 29/05/2011
After getting back from Florida, I wanted to make sure that I wasn't completely spoiled by the warm water, and went out on the Topline with Mihai.
We did the Collingwood Day Marker, and Wolcombe Island. The day was sunny and awesome. I had some good time talking to Kevin and Jan about the Florida trip, since they spent a lot of time in that area themselves.
Here is a short clip of Mihai. The lighting made it look quite other-worldly.

Marathon Florida 13/05/2011
I'd been looking forward to this for a long time. Heather and I had planned a trip to Florida for a dragon boat festival and some diving. We ran into some weather on the trip down, so we ended up being late and very tired, so we put off diving until the next day. Serendipitously, on exploring around the hotel, we saw a dive boat moored off the back dock. We ended up diving with Captain Hook's dive charter the next day, and just had to walk out the back door!
We did two dives on one of the Florida reefs. Helping out on the boat was Denise, a great lady. Also on the boat were some recruits from the local coast guard doing some dive training. On the boat ride out, we came across a rickety water-filled boat made of all manner of flotsam and jetsam. Apparently there were attempts by Cubans to come across to Florida on boats like this. I forget the name the Coast Guard people called it. They ended up calling in the boat to the Coast Guard, but we didn't see any people fortunately.
The two reef dives were awesome. I got to try out my warm-water gear, and we saw some great fish. We saw parrot fish, some tube fish, a small shark, and lots and lots of coral. The water was so clear and warm, it was grand. Without all my cold-water gear it seemed very liberating. I still didn't get converted to solely warm-water diving like some people said might happen. Both have their charms to me.
I had my GoPro video camera along, and made a short video of some of the things we saw. There is also a small portion of the snorkeling we did too!

Nanaimo Wrecks 16/04/2011
Jason Kolba and I signed up to go on the new/old SeaDragon that was now running out of Nanaimo. Dan from the Mamro was captaining it, along with Christine who helped do some of their accounting, and was also a dive master. Christine said that she already felt she knew Jason and I since we had been out on the Topline and Seadragon more times than anyone in the last year. We both thought that was pretty funny.
The Seadragon was much as we had remembered it. Nothing had changed. There was still the upper sundeck that was great in the sun but crap in the wind/rain. The back swim grid was roomy and Jason and I were put there with our doubles. These two benches were the only real area for doubles anyway as there were cylinder circles welded onto the benches. The midship deck was still covered but a bit cramped. 8 divers could get in there in a pinch but it wouldn't be fun. Jason and I were lucky to have the swim grid to ourselves. The reward for diving doubles I guess! I had my stage along too just for fun.
We had a pretty full boat. An instructor was doing the final dives for a class, and some others from out of town were fun-diving for the whole weekend.
Christine and Dan made the trip very pleasant. Coffee, soup, nanaimo bars and lots of friendly chat and help. Dan had a few stories about Steve Redding who from IDC who used to help on the Mamro dive charter for him.
The day started off cold but sunny. It turned miserable for a time during our surface interval but then turned sunny again for the trip home.
We did the Cape Breton first. Our dive plan was for 50 minutes and an average depth of 80 feet. We were going to circumnavigate the wreck, but current stopped us from getting as far as we wanted. Visibility was not that great either, maybe 15 feet. Too bad since it was Jason's first time on them. It was still a good dive though. We went through some of the swim-throughs and saw some big cabezon along with rainbow shrimps. On the ascent I did a mask removal for practice and froze my forehead. The water was cold!
On the surface the weather had turned. It was choppy, rainy and windy. Not nice! We had some lunch and relaxed a bit. My new Xen dive computer's battery failed, which wasn't good. However several other people had reported the same problem. Guess mine had it too. Good thing I had my backup bottom timer.
We moved the boat to the Saskatchewan and geared up for the next dive. The chop made it difficult to tie up the boat. Christine and Dan tried 4 or 5 times before success. We went down amidships, and followed a similar 50 minute dive profile, but with a shallower average depth. We checked out the deck guns first, and I took out the new dive buddy, JD (Just Duck) for a photo shoot. I had to stick him inside the gun barrel because he floated so much. It was also pretty impressive how crushed he was at 90 feet! Poor guy.
Stuff we saw were large cabezons, a brown box crab, a huge yellow eye rockfish, and tonnes of anemones. Everything seemed covered in them. There we're no nudibranchs that I saw, except for a shag mouse nudibranch on the ascent/descent line.
A good set of two dives, and it was good to see a good charter operation move into Nanaimo now that Diver's Choice had met such hard times and closed.

Tuwanek 26/03/2011
Jason Kolba and I wanted to circumnavigate the North Island of Tuwanek now that he had gotten his double cylinder setup. One long carefully planned dive was very appealing, rather than doing two separate ones with a surface interval. Our planned dive time would be 90 minutes, with an average depth of 40 feet using 32%. We hit that exactly.
The dive was good, but the visibility wasn't as great as Tuwanek usually is. That was one of the big reasons to go! It was too bad, but it wasn't a show stopper.
At the beginning of the dive, we got a bit turned around moving around the East side of the North island, but got that sorted out. We found the wolf eel, but he looked to be alone. Jason commented later that he looked sad. Maybe because his mate died? Not sure. I got some obligatory video of the wolf eel. I swear that it is one of the most videoed and photographed critters around. How he puts up with all the divers poking their nose into his lair with their lights and cameras I don't know.
At the end of the dive, we did some valve drills and S-drills. They went pretty well. We videoed each other so that we could see how we did.
A fun trip!

Northerner of Clyde UASBC 19/03/2011
Jason and I went out with the UASBC to help survey a wreck near Egmont called the Northerner of Clyde. The UASBC had dove it before in April 2010, and we were lucky to have one of those people along; Tim Novak.
We had to catch the early ferry to the Sunshine Coast, so it was a very early start. Everyone met up in good order and we made the ferry in plenty of time. Time enough to get a coffee in Horsehoe Bay fortunately, since I needed it!
On the trip over we prepped dive slates with Mylar and the dive instructions. Keith did a great job breaking out each team's responsibilities. We had three teams: one doing the deck, one doing the port and one doing the starboard. Main team activities were to get more accurate measurements of the wreck, get a compass bearing and document the overall layout.
When we arrived in Egmont, we met Bryce of B Line Charters. He had a water taxi / dive boat that would take us out. I learned later that Bryce had also sold the Topline boat to Kevin and Jan of Sea Dragon Charters. The dive community certainly was small!
The B Line boat was not badly set up, and fit us comfortably. There were no real benches, but there was a step down area where you could put on doubles. The main stumbling block was no ladder! Bryce said it was in Vancouver. Later I'd actually meet the guy making Bryces's ladder, on a trip over to Tuwanek.
It didn't take long to get to the dive site. We didn't know precisely where the wreck was, so Jason and I volunteered to find it. We also decided to do the port side survey.
I brought my new birthday present along on this dive, the GoPro Hero video camera that Heather got me. I left it on for the entire dive, and got some pretty interesting video. Hopefully I can post some soon.
Descending to the bottom at about 60 feet we started looking. Visibility was very good, and we quickly located the wreck. Although as I recall, I was looking in the opposite direction, and it was Jason who found it. I shot a surface marker, and we took a tour of things before getting into the tasks.
The first thing I noticed was the prop. It was still attached and in good shape. It looked great. The wreck itself was a lot smaller than either of us had figured at about 21 meters or about 70 feet. A lot of it had collapsed in, but the wheel house was still intact. The port side was pretty deteriorated, with a lot of holes. The vessel listed to port as well, to about 30 degrees, but overall upright.
We found a lot of debris and artifacts scattered on the bottom by the port side. Some things of note were coffee cups, plates, pulleys, tires, deck hatches and a metal box.
We completed our tasks pretty well but could not identify any engines or other machinery. It was too difficult to see inside the hull.
While surfacing I got some interesting video of of everyone on the way up. The bubble show was very cool.
Getting back on the boat in doubles with no ladder was tricky. We took our rigs off and climbed aboard, but hoisting the cylinders back on. Yuck. Ladders were good!
After some lunch we had to decide what to do next. In the end the Power Lines won out. They were not far from the wreck, so we headed back that way.
I had done the power lines before, and I was looking forward to it. It was an awesome dive. Tonnes of cloud sponges, as well as chimney sponges. We found one very interesting fish that was some sort of sculpin. There were some really nice frosted nudibranchs too. I will let the video that I should have together soon speak for me. The sun started to come out too which really helped brighten things up.
All in all, a very successful and enjoyable trip.

Whytecliff Scooter Dive 06/03/2011
Scooter dive at Whytecliff with Vince Janelle and John Campbell. Vince had his X-scooter out, and John had his short body Gavin. I brought out my stage bottle as well for practice.
At the beginning of the dive, John had a small leak in his dry-suit, but we fixed that. He just needed to adjust his neck-seal.
We went up the Cut, but cut the dive a bit short. Vince was having trouble equalizing. After we got back in, John and I went back out quickly and tried a few barrel rolls. He did a lot better than I did. I ended up on the bottom upside down a few times, hah.
I also took out my birthday present, and here are some pictures and video here:

St. George's Pool 24/02/2011
Jason Kolba got his double 130's, and he asked if I'd go do some pool-practice with him. It was always good to work on skills, so I was pretty happy to go.
Everything went pretty well. IDC was there with a dry-suit class, so we did have to avoid some students. Jason rocketed to the bottom on the first descent because he wasn't used to the buoyancy change of the doubles. But he did well. We ran through valve drills, S-drills and some helicopter turns and other propulsion. I tried my best to demonstrate things as well as possible, but messed up on one valve drill. But that's when you want to mess up, in a controlled situation. It was a good learning experience, that's for sure!

UASBC NAS Intro Course 19/02/2011
On Saturday February 19th, Jacques Marc and John Middleton put on a Nautical Archaeology Society Intro course for the UASBC.
The NAS site, and the course write-ups are here:
http://www.nauticalarchaeologysociety.org/training/index.php
The UASBC site, and the course write-up is here:
http://www.uasbc.com/introtonascourse.cfm
There were some pictures taken by John that I put up here. The first two are of the land-work we did, then there is myself doing some tasks in the pool, then a group shot.
https://picasaweb.google.com/AntonNorth/ScubaFeb2011NASCourseVictoria#
The full course participant list was myself, Jason Kolba, Keith Bossons, Greg Bossons, Greg Nuttall, John Campbell, Joe Smith, Rob, Randy Parke, and Jiri Kotler. We met at the Crystal Pool and Fitness Centre in Victoria, and it was a beautiful sunny day. Many of us came over the night before to have more of a civilized morning arrival, but a few like Keith and his son came over that morning. Jason and I crashed at Jaques' house, which was very nice of him. He even made us pancakes!
There was some organizing to be done in the morning, as the room was not quite ready for us. Fortunately everything went relatively smoothly, although Jacques had to drive to his office to get a projection screen.
We started with introductions all around, and explanations as to why each of us were there. It was quite a mixed group. Most of us were there to expand our diving in some way. Some mentioned wanting to dive more wrecks, some mentioned learning new skills. One mentioned how it may help directly with his occupation (RCMP police diver; very interesting!). For me, I was there have fun at a new aspect of diving and to learn new skills.
Jacques handed things over to John, who started everything off with an introduction to the NAS program and the types of archaeology. After that, Jacques ran us through underwater survey techniques and the skills we would be practising in the pool. We had some donuts and coffee and headed outside to do some dry-land survey practice in the playground. I found the trilateration exercise very interesting. Taking two measurements from different points really made sense in helping increase accuracy when measuring things. Jacques also went over some of the things we might forget in the pool session. Tips on how to get better measurements, checking the markings on your tape, going over how you will measure things before you get in the water, and things like that. He joked that he still fully expected everyone to make all the usual mistakes, but that was part of the learning process (and the fun!).
We got changed and set up our gear at the deep end of the pool. Jacques had help from Holger who set up the underwater portion of the course before hand.
Each of us were split off into buddy teams, and sent on the various objectives. The tasks included three exercises. One was doing a perpendicular measurement of several items to a baseline. There was a scuba cylinder, a mitre box and a tape measure. On the other baseline we had to do bilateration (the trilateration we learned, but a bit less accurate). On that one there was an elbow shaped PVC pipe and a home base plate. It was tricky to get enough measurements to reproduce the objects accurately later. We ended up going back to both of the exercises to re-do and make some new measurements before we got out of the pool.
The final exercise was to sketch several objects under a grid. I had to sketch a dive knife, a light, and a garden hand-rake. It was very hard. You had to keep the grid at the same distance or things would be off. Buoyancy and being able to keep your position was very handy. Part of the trick was to keep the grid-lines lined up with each other, since there were two sets, one under the other. So if the lines were one, you were in the right spot. Jason and I did an extra exercise by doing a side profile of the side of the pool.
After all that, we did one last lecture on maritime law and plotted our measurements. We did it on tracing paper to a 300 scale and used simple drafting tools. I figured I'd be buying grade-school math equipment again! Once it was plotted, everyone put their plots on the window. With the tracing paper, the light shinning through let you see how everyone's matched up. The tape measure moved all over the place. People kept picking it up and putting it down, because it didn't look like part of the exercise! Jaques had some good comments to help people do better measurements, and said that we all did a pretty good job.
It was a great course in the end. I learned a lot and it was very interesting! Jason and I would be putting the course material to work on the next dive, which was coming up fast.

There were some pictures taken by John that I put up here. The first two are of the land-work we did, then there is myself doing some tasks in the pool, then a group shot.

The full course participant list was myself, Jason Kolba, Keith Bossons, Greg Bossons, Greg Nuttall, John Campbell, Joe Smith, Rob, Randy Parke, and Jiri Kotler. We met at the Crystal Pool and Fitness Centre in Victoria, and it was a beautiful sunny day. Many of us came over the night before to have more of a civilized morning arrival, but a few like Keith and his son came over that morning. Jason and I crashed at Jaques' house, which was very nice of him. He even made us pancakes!
