From "Shaggy Mouse" Nudibranchs and Giant Sea Spiders to Juvenile Wolf Eels - it's a great spot to shoot photos and to enjoy making a dive plan for a moderately current intensive dive site (read: OW classes aren't held here). The eel grass looks like wheat, blowing in the wind - to be enjoyed during your safety stop, and there's the occasional score that a bottle hunter can enjoy finding at this dive site. ]]> http://www.calvintang.com/blog/2009/09/bottle-hunting-alki-junkyard/feed 4 http://www.calvintang.com/blog/2009/08/beneath-emerald-waters http://www.calvintang.com/blog/2009/08/beneath-emerald-waters#comments Fri, 28 Aug 2009 21:58:58 +0000 Calvin http://www.calvintang.com/blog/2009/08/beneath-emerald-waters http://www.calvintang.com/blog/2009/08/beneath-emerald-waters/feed 0 http://www.calvintang.com/blog/2008/10/diving-the-warren-car-lake-crescent http://www.calvintang.com/blog/2008/10/diving-the-warren-car-lake-crescent#comments Wed, 01 Oct 2008 18:57:48 +0000 Calvin http://www.calvintang.com/?p=127 This past weekend a group of Northwest Dive Club buddies and I headed out to the Olympic Peninsula to dive in Lake Crescent. This alpine lake is nestled in the Olympic National Park, a temperate rainforest and one of Washington State's great natural treasures. Among the group of technical divers in attendance, we had four gentlemen who played various roles in the solving of a 72 year-old mystery, involving the disappearance of a young couple back in the late 1920s. A team of divers was able to discover the location of the submerged car that carried this young couple to their tragic deaths, so many decades ago.]]> http://www.calvintang.com/blog/2008/10/diving-the-warren-car-lake-crescent/feed 3 http://www.calvintang.com/blog/2008/09/solo-rebreather-dive-macro-photography http://www.calvintang.com/blog/2008/09/solo-rebreather-dive-macro-photography#comments Thu, 18 Sep 2008 07:18:23 +0000 Calvin http://www.calvintang.com/?p=122 Today I did my first solo CCR dive, and brought along the new Nikon D300/Subal ND30 rig. It was also my first time using the 105mm macro lens (and accompanying port). I didn't get fantastic shots, but it was one of the most challenging, complex dives I've ever done, simply because there was so much to think about (both camera and CCR) and no buddy to depend on or ask for help.]]> http://www.calvintang.com/blog/2008/09/solo-rebreather-dive-macro-photography/feed 1 http://www.calvintang.com/blog/2008/09/tribute-to-edmonds-oil-dock http://www.calvintang.com/blog/2008/09/tribute-to-edmonds-oil-dock#comments Tue, 09 Sep 2008 06:36:55 +0000 Calvin http://www.calvintang.com/?p=114 One of my favorite dive sites in the Pacific Northwest is about to be destroyed, so I went diving there recently with a couple good buddies and shot the last photos I'll ever take at this gem of a dive site. A long story short, Governor Christine Gregoire's Puget Sound Initiative aims to remove pilings in our waters containing the chemical "creosote". But, there are several red flags pertaining to the selection of this site, among hundreds to choose from, since this particular set of creosote pilings happens to be home to an abundant amount of local marine life.]]> http://www.calvintang.com/blog/2008/09/tribute-to-edmonds-oil-dock/feed 2 http://www.calvintang.com/blog/2008/06/advanced-trimix-for-closed-circuit-rebreathers http://www.calvintang.com/blog/2008/06/advanced-trimix-for-closed-circuit-rebreathers#comments Tue, 17 Jun 2008 00:41:13 +0000 Calvin http://www.calvintang.com/blog/2008/06/advanced-trimix-for-closed-circuit-rebreathers Well, this afternoon my good dive buddy Nailer and I (and our new buddy Larry) threw up our caps (hoods?) as we graduated from Advanced Closed Circuit Rebreather (CCR) Trimix class (I believe this is called Mod 3 in Europe). This means that I can use hypoxic amounts of oxygen (less than 16%) mixed with helium and nitrogen, in various amounts, as diluent when mixing with pure oxygen in a closed breathing loop. I am now certified to dive to 330 feet, which opens up a lot of diving options. It seems like forever ago, but just 7 months prior I started my first CCR class, Air Diluent CCR cert. It did take me months to find the groove on the Meg, but sometime along the way it just clicked. I'm glad I stuck with it because honestly, those first dozen dives or so had me thinking, what have I done?. Now I feel pretty natural in the water again, not as carefree as on OC before I made the switch, but definitely confident, which is huge.]]> http://www.calvintang.com/blog/2008/06/advanced-trimix-for-closed-circuit-rebreathers/feed 3 http://www.calvintang.com/blog/2007/11/copis-megalodon-ccr-training http://www.calvintang.com/blog/2007/11/copis-megalodon-ccr-training#comments Fri, 23 Nov 2007 23:18:14 +0000 Nailer99 http://www.calvintang.com/blog/2007/11/copis-megalodon-ccr-training My dive buddy Josh, aka Nailer99, offers up his account of our recent COPIS Megalodon CCR training from Silent Scuba instructor Mel Clark. All day, every day for a week solid - this was some of the toughest dive training I've ever done - but the end result is that we can now stay down for hours on end, and this opens up our NDLs tremendously so that we can stay deeper for longer. With virtually no bubbles, fish and other marine life came right up to us. I can't wait to shoot some stills and video with the mCCR. I'm looking forward to doing many dives with my new COPIS. It wasn't cheap (in terms of time or money) but the training corresponds to the higher level of proficiency and diligence needed to dive a Closed Circuit Rebreather like the manual Megalodon from Innerspace Systems.]]> http://www.calvintang.com/blog/2007/11/copis-megalodon-ccr-training/feed 10 http://www.calvintang.com/blog/2007/10/lightmotion-bluefin-sony-hdr-hc7 http://www.calvintang.com/blog/2007/10/lightmotion-bluefin-sony-hdr-hc7#comments Thu, 04 Oct 2007 14:00:57 +0000 Calvin http://www.calvintang.com/blog/2007/10/lightmotion-bluefin-sony-hdr-hc7 After taking a few videos of sixgill sharks lately, I realized just how lacking my Casio EX-Z1050’s video capabilities are. So, I decided last week that it was time to take the plunge and so I’m delving into the world of underwater high-definition video. I won’t tell you much about it yet, since I haven’t even gotten this rig wet yet - but I’ll leave you all with some photos that should make your mouth water.]]> http://www.calvintang.com/blog/2007/10/lightmotion-bluefin-sony-hdr-hc7/feed 6 http://www.calvintang.com/blog/2007/08/sixgill-shark-sighting-video http://www.calvintang.com/blog/2007/08/sixgill-shark-sighting-video#comments Sat, 04 Aug 2007 13:00:45 +0000 Calvin http://www.calvintang.com/blog/2007/08/sixgill-shark-sighting-video Tuesday evening a couple of dive buddies and I came across an 8 foot SixGill shark in Cove 2. We followed the shark for about five minutes (which seemed like an eternity). The two SixGill sharks I've encountered thus far both didn't exhibit aggressive behavior (actually, the first one seemed sluggish). The shark swam gracefully while I captured the video of her. It looked as though she had been tagged at one point, but that the tag had since been dislodged. Also on this dive, I found a mask belonging to a diver who passed away the night before in a dive accident that is still under investigation.]]> http://www.calvintang.com/blog/2007/08/sixgill-shark-sighting-video/feed 1 http://www.calvintang.com/blog/2007/07/dui-cf200-crushed-neoprene-drysuit-review http://www.calvintang.com/blog/2007/07/dui-cf200-crushed-neoprene-drysuit-review#comments Fri, 20 Jul 2007 15:00:01 +0000 Calvin http://www.calvintang.com/blog/2007/07/dui-cf200-crushed-neoprene-drysuit-review The exposure suit is perhaps the biggest difference maker when it comes to enjoying your dive. Even with the best equipment, dive buddies, location and experience - if you have an inadequate exposure suit for the conditions you’re diving in, you won’t have fun. In the worst case, you may not even be able to safely dive without the proper thermal protection. After diving a starter suit for a year, I finally threw down the duckets and bought myself a custom suit from DUI. With more available options than a Wall Street broker, the CF200x is simply the ultimate drysuit.]]> http://www.calvintang.com/blog/2007/07/dui-cf200-crushed-neoprene-drysuit-review/feed 10
