Welcome to dive.roko.ca!

I’ve stared putting up dive photos and information on my robotics blog, roko.ca, but somehow it just didn’t see to fit in with quadrupeds and sumo robots. As such, I’ve decided to start up this diving specific blog, where I’ll share photos from my dive experiences, mainly for terrestrial-bound friends and family, to show the wonders of the Emerald Sea, and other dive trips I go on!

I’ll slowly start uploading old photos, and will update whenever I go diving, so stay tuned and subscribe to my RSS Feed!

Hangin' out on a safety stop. (Not in BC)

Decorator Crab

After a crazy week of Vancouver snow and freezing rain, I skipped on over to Whytecliff park for a couple of dives. Luckily it had warmed up to above zero, and the snow had been washed away by all the rain. Unfortunately, the rain appeared to have washed the snow straight into the ocean, causing some pretty bad viz (10-20 feet.. Bad for winter, good for summer!) and cold temperatures on the dive.

At Whytecliff itself, there were some swells making entry and surface swimming a lot more fun. The tide was high, so we didn’t have to scramble over too many big rocks to get in. Instead of surface swimming around towards the day marker, we elected to descend early and go through the bay underwater to avoid some of the swell.

Sunstar Arm

If you've ever wondered what the tube-feet on one of a Sunstar's many arms look like, this is it.

Underwater I didn’t feel it was my best photography day, as I didn’t find too many critters posing nicely (though I found quite a few who flat out refused to co-operate). I spent a large portion of the dives fiddling with my buoyancy and trying to stay still in the frigid waters. (The coldest my computer read was 43 F, but it has an averaging algorithm that I think misses some of the more brutal thermoclines).

At some points on the northern part of the bay, you could see where the fresh water runoff was mixing with the salt water. Always a trippy effect that makes it hard to see, as everything turns blurry.

Even though the sun wasn’t out, it was fairly bright at around 20ft, so I attempted to take some shots without the flash in the shallows. It was a bit awkward, as making the shutter speed any less than 1/60s introduced too much motion blur, while pumping the ISO up to 400 introduced too much noise in the camera. Fiddling with the RAW files made things look  more interesting. Unfortunately, the poor vis made it hard to take any decent shots. It did make me wish I had a wide angle lens for this camera, however…..

A Black-eyed Hermit Crab

After scraping the ice and snow off of my Jeep this morning, I made my way down to Porteau Cove with one of my dive buddies. It was a nice day hovering around zero, with a light dusting of ice and snow on the ground. Perfect for drysuit diving in cold water!

I’m pretty sure my computer measured the water at the surface at about 39 degrees F, but thankfully at depth it warmed up to about 44 degrees F. We managed two good dives, about an hour long each. My new Santi hood managed to keep me much warmer than my old hood did, so I didn’t get too chilled. For the second dive I did have to throw on an extra 4 lbs of weight so that I could inflate my drysuit some more…

I managed to get some nice pictures on this dive that I’m happy with. Without further addoo, here are the photos:

Squat Lobster

This guy and several of his cohorts were hiding in a crack in the rocks. I think it's a Squat Lobster (aka "pinch bug")

A very small Anemone. There were plenty of these tiny guys on the wall.

In the fall, Paul introduced me to Furry Creek. Since then, I’ve been back a couple of times, and really enjoy it as a dive site. The wall has a nice amount of life (including a wolf eel!), plus in the shallows are some old bottles to dig through. This time around I found Pepsi-Cola bottle from the early 1950′s.

It was my first trip out with the camera in a while. The first dive I dove with the case empty, but satisfied when there were no leaks I took the camera with me on the second dive. I managed to get a few good photos, however right when I found a giant frosted Nudibranch that I really wanted a photo of, the strobe stopped syncing. I’ll need to adjust the fiber optic sync setup I’ve jury-rigged before my next dive.

Without further adoo, the photos are below.

New Case!

I lucked out recently and found a used Ikelite case for my camera, for a very good price. I snapped it up, and now have a new camera case. I still need to get a new strobe arm that’s compatible with the tray, and do a test dive without the camera to ensure the case seals up tight, but it looks like I’ll be posting underwater photos again soon!

The case feels much more professional than the Canon case, and hopefully will prove to be sturdier. The photo below shows a nice comparison in the size and construction between the two cases, with the Ikelite case on the left, and the WP-DC28 case on the right.

Ikelite (L) and Cannon (R) Cases

 

Just a quick note, the enclosure for my camera broke. To make matters worse, I’ve had a few good dives since then where I really wished I’d had my camera!

Anyways, I won’t be posting any photos for the next little bit until I can fix or replace my case…

Birds on the lifeboat crane.

… Another day closer to sinking it.

We went for an evening dive after work yesterday. Unfortunately, I didn’t get any good photos, but a seal did come visit us underwater for a while!

Scuplin

A Really Cool Sculpin

Andrea, a friend and dive instructor was leaving for New Zealand for a lengthy period of time, and organized a great going away barbeque and dive day at Whytecliff. When we got there, Paul and I rushed to get into the water. The first dive I took my wide angle lens with me, and we dove the islet in the hopes that the seal we’d spotted on the surface would come visit us. He didn’t. That jerk. Unfortunately the Vis wasn’t so great, so I didn’t manage to get a lot of good photos with the wide angle on the first dive. However, we did see a really cool scuplin. On the way back through the bay, I spotted an octopus hiding beneath a concrete block, though he was way too tucked in to manage a good photo. After the dive, on our swim back to shore we saw a mink hop into the water and take a quick swim. Way too cool!

Hermit

Hermit Crab! (And a tiny Nudibranch)

On our second dive, we swam around to the plumose gardens. It was amazing how much life there was in the area. Not only were there tonnes of plumose anenomes as the name implied, but there appeared to be a large population of hermit crabs which I managed to snap a few  great photos of. Part way through the dive, we hear a VERY loud boat overhead, I assumed it was the ferry. Carrying on, plenty of other fish were to be seen. It was an amazing dive, and I pulled some great photos from the camera.

I pulled close to my NDLs on this dive as I was on Air. I thought I’d save $10 and not get my usual EAN32 fill, as I had intended to do some shallower diving with these tanks on a dive day that ended up being cancelled. As a result I had a less than optimal gas for the dive, and had to ascend earlier than I would have liked to avoid going into deco. With plenty of gas left in the tank, but a nitrogen loading preventing me from staying at an interesting depth, I spent 10 or so minutes practicing holding mid-water stops at 20, 15 and 10 feet, using only my computer and the silt in the water as a visual reference.

Octopus (Cake)

An Epic Octopus Cake!


Once we surfaced we noticed that a hovercraft had come into the bay and parked on shore for a good will visit (and for some free BBQ food!). As it ends up that loud ship we’d heard wasn’t a ferry, but the hovercraft coming in. I’ve posted photos in another post.

For Andrea’s barbeque, someone had made an incredible octopus cake, clutching a detailed scuba diver. The attention detail in the cake was so amazing, the eye even looked like an octopus eye! It was a shame to eat it in the end.

A great day with great people. And Andrea, if you’re reading this from NZ, I hope you’re enjoying your trip!

More photos are below. I’ve added notes regarding some specific images below if you view them full-sized.

CCGH Siyay

Siyay

This is what we found when we surfaced...

The Coast Guard Hovercraft Siyay came to visit Whytecliff while we were diving. They said it was for a sort of public outreach, but I secretly believe they just came for some burgers at Andrea’s going away barbeque. We heard it coming in when we were underwater, but just dismissed it as a really loud boat. Upon surfacing, we noticed it parked there!

Touring around inside the hovercraft was really cool. It’s a somewhat dedicated dive vessel, with the first room containing drysuits ready to go, the second room had dive gear set up for demonstration, and the room after that containing tanks of breathing gas for surface supplied diving.

In case you recognize the name, the Siyay was the vessel which transported the porpoise Siyay to the Vancouver Aquarium’s Marine Mammal Rescue center to try to save it’s life. The porpoise was named after this hovercraft.

More photos of the hovercraft below!
