Redondo - Two Divesites in One!

I sometimes forget how lucky we are to have such diverse dive sites so accessible in the Seattle area. Redondo is one of those places with great facilities... across-the-street parking, easy entry access, short surface swims, Salty's restaurant when you're finished... but also two completely different dives conveniently organized along underwater lines. This makes for a great two-dive outing without having to move the car!

Today, my friends Dennis & Aimee joined me for a dive along the "Deep Line".

Ninety five feet max depth for 34 minutes, water temp 49 degrees. Under one of the boat wreckages, it was obvious that there was a Giant Pacific Octopus but we didn't stop to look as there were already some divers checking it out.

What impressed me most of all was the sheer number of shrimp! They were EVERYwhere. I did a REEF survey after the fact and wanted to select whatever comes after 'Abundant'! On our way back up the slope, Dennis found a Bay Pipefish, about 16" long. It was the first time I had seen one other than at the Seattle Aquarium. So it's always cool to see new things!

What else did we see?

Plumose anemones, both dungeness & red rock crabs, the bay pipefish, a fish-eating anemone, kelp crabs, sunflower and spiny pink seastars, copper rockfish and painted greenlings.

Second dive was max depth of 57 feet and just under an hour long. Dennis and I went without Aimee, who was having drysuit issues. It's no fun being wet in a drysuit. :-(

We found the line to the VW Bug - my first visit! In the past, I think I've hit the skinny line and followed it but it stops. A little deeper is a thicker line that connects all the items of interest - the VW Bug, piles of what appear to be streetlight covers, boat wreckages, etc.

What did we see this time?

This time we saw two Giant Pacific Octopusses - one under the passenger side of the VW and another under a boat. We also saw a cute lineup of five penpoint gunnels under the driver's side. I had never seen a buffalo sculpin at this site but we did find one individual and Dennis got some great dramatic photos of it. Definitely would go again.

Great new addition to Edmonds Underwater Park


Yesterday Meghan & I did a Naturalist dive as part of her AOW certification at Edmonds Underwater Park (now technically known as "Bruce Higgins Underwater Trails"). The weather was blustery, lots of surface-driven waves but calm underwater - we ended up having a fantastic dive: 42 feet max depth for 60 minutes, water temp of 50 degrees.

There is a new addition to the park as of a week or so ago - a 100'L x 20'W x 19'D barge that lies just a few feet to the west of the Triumph. It was sunk without much fanfare other than Edmonds locals saw the "big crane barge" helping but it down. Lots of mussels on the sides but squeaky clean on top and inside. It's marked by two 55 gallon blue drums. We decended on the white ball with the dive flag on it which was inline between those drums. This put us right on the Triumph. Boy had it deteriorated since the last time I saw it a few years ago. But it's a magnet for Lingcod and Rockfish which makes it still appealing.

The new barge has large openings on top which reveal rooms the whole depth of the structure. I think this would be a good opportunity for a wreck class but we didn't come prepared for penetration so we just looked over the lip of the rooms. If you want to penetrate - and it's oh so appealing - make sure you have proper training and equipment. Soon there will be silt inside which will make for a low viz, overhead environment which isn't appropriate for beginners or for anyone without a line to the exit. The barge itself is propped off the bottom by a couple of feet. Something about permitting that didn't allow them to put the barge directly on the bottom. Certainly not safe for going under the structure but fun to peek underneath - we saw the giant lips of a Lingcod wondering what the heck we were shining our light at!

Since it was a naturalist dive, we saw Kelp Greenling, Lingcod, Painted Greenling, Longfin Gunnel, Penpoint Gunnel, Black Rockfish, Copper Rockfish, Quillback Rockfish, Cabezon, Kelp Surfperch, Pile Perch, Shiner Surfperch, Striped Seaperch, Tube-Snout, Coonstripe Shrimp, Dungeness Crab, Northern Kelp Crab, Red Rock Crab, Lacy Bryozoan, Fish-eating Anemone, Plumose Anemone, Sunflower Star, White-lined Dirona, Northern Feather Duster Worm, Hooded Nudibranch, Clown Dorid and a Shaggy Mouse Nudibranch. 27 species in total!

Very nice dive. Made for a much more interesting REEF survey than Seacrest Cove 2. Must remember that the long surface swim is well worth it - and there is plenty of great structure on Jetty Way on the way in so you don't have to spend all your time on the new barge or Triumph. Hope you can make it there soon!

Thanks Meghan for being a great dive buddy!

Convenience & Value


Recently I was talking with another PADI Pro about the Advanced Open Water program, its intent, conduct and marketing. We agreed that students who hold this rating aren't necessarily experienced divers but that the course was that opportunity for a student to gain more experience under an Instructor's direct supervision.

We talked about pricing. The 'going rate' in Seattle seems to be about $150, some Instructors charging more, some far less. But the programs are not nearly identical in value. The lowest price offerings often include specialties that are easy to teach rather than popular and in some cases, the Instructor is trying to push so many people through the course that they don't even get in the water with students, leaving their Staff to do that.

Many Instructors choose not to conduct a night dive because it's logistically challenging and anxiety can be high. But isn't that the role of an Instructor that wants to teach? Other Instructors use the boat adventure dive as one of the electives. Boat ettiquette and procedures are important but not knowing these isn't necessarily a safety issue. Night diving is often the only option during the winter workweek in Seattle. Students should be encouraged to experience it rather than forgo 5/7ths (71%) of their winter diving opportunities.

When researching an Instructor to take your Advanced Open Water course from, be sure to interview them about whether they'll be getting in the water with you, how many other students will be joining you, what adventure dives they'll conduct and why you'd benefit from those chosen.

My Favorite Things

Here was my Xmas list for others. Books, music and videos.

Not for me, 'cause I already have everything. But things for that 'tough-to-buy-for' diving relative of your's. Enjoy!

Seattle Restaurants serving Sharkfin Soup

Many people don't realize that hundreds of thousands of sharks are finned alive every year, their defenseless LIVING bodies thrown overboard where they'll die an agonizing death. All so that some affluent asians (the dish costs up to $100/bowl) can show off their success. In general, humanity has wized up on elephant and rhino ivory trade when it was learned that poachers would simply kill the animals for the tusks. The 'civilized' world was repulsed by that. There is no difference between the anti-ivory trade movement and this, which is why it gives me hope that if people are educated, they'll do the right thing. Poachers are economically encouraged to continue unless the market evaporates. You can help by choosing not to patronize restaurants that serve sharkfin soup.

Some of these restaurants accurately protest that the 'fin' is made from flour and crab but it still condones the practice and it's unacceptable in our 'modern' society. The 'culture' of slavery was once in fashion too so don't buy that it's just part of chinese culture. Cultures evolve! This tradition originated 2000 years ago when capturing a shark was a nearly impossible feat. Now sophisticated technology has decimated some shark populations by 90%+ in the last 3 decades. Sharks play an important role in the ocean ecosystem by keeping everything in check. They're not the indiscriminant human killers portrayed in the movies.

It's not enough just to not eat the Soup... please don't frequent these restaurants and endorse their support for the shark finning industry. If you feel strongly about this, as I do, consider calling up the restaurant and mention that you wanted to bring a large party there but chose not to because of their objectionable menu.

Please lead by example and choose not to support these restaurants until they publicly reform their policies.

Another thing you can do is print out cards at the Animal Welfare Institute to leave behind if you accidently find yourself at an asian restaurant and find sharkfin soup on the menu.

If you must eat this dish, consider this - there is evidence that eating shark fin leads to sterility.

Smoking and Diving


Last year I was on a dive boat where – for the first time in my experience – the majority of divers smoked cigarettes between dives. We’re taught in basic OW class that smoking & diving is bad so I decided to research exactly why it’s so detrimental to a diver’s health in particular. I don’t want to ‘lecture’ about the merits/politics of smoking. I want to communicate the physiological effects which are evidence-supported – not theories – in an effort to educate. Addicted smokers will find a way to rationalize away all of these findings, but these effects are well documented and supported by diving medical experts:

  • Carbon Monoxide (CO) binds to hemoglobin 250x tighter than oxygen. This prevents hemoglobin from carrying O2 from the lungs to the cells and CO2 from the cells to the lungs. The smoking diver is more hypoxic and any stressful situation – entering or exiting the water? – puts the diver at increased risk for a hypoxic-related event, such as a heart attack.

  • Nicotine causes a short-term increase in blood pressure, heart rate, and flow of blood from the heart. It also causes arteries to narrow. The reduced O2 blood combined with the effects of nicotine will create an imbalance in the demand for oxygen and the body’s ability to supply.

  • Obstructions in the lungs, caused by chronic pulmonary disease attributed to smoking, markedly increase probability of pulmonary barotraumas and arterial gas embolisms.

  • Many smokers have nasal and sinus drainage problems – this increases their chances of middle ear and sinus blocks and squeezes.

  • Cigarette smoke in the nose paralyzes the movement of cilia – the microscopic ‘hairs’ that are supposed to trap foreign particles – for approximately 1 hour after one cigarette. In chronic smokers, the cilia is completely destroyed. Thus smokers' noses are not able to clear dirt, bacteria or other debris as effectively, which promotes infection.

  • Chronic smoking damages the lungs so that the surface area where gas exchange takes place is reduced. Unfortunately, the non-active person uses only 25% of their lungs and they can smoke until over 75% of their lungs are destroyed before they will notice shortness of breath in daily activities.

Thanks to Dr. David Sawatzky (“The Diving Doctor”), Dr. Paul S. Auerbach, Dr. Ernest S. Campbell (“Scuba Doc”), Diver’s Alert Network and Dive Training magazine for their articles on the web. They were consistent, insightful and in easy-to-understand language.
