An early nighttime muck dive in Penn Cove last night revealed a couple of things (apart from the shrimp, crab, octopus and jetsam) that I haven't noticed yet during a few "fishless" daytime dives. Anyone care to enlighten me with ids and stories? In a drab soft bottom of clam middens(?) th...

super high resolution bathymetry available thanks to the NOAA Hydrographic Survey: https://maps.ngdc.noaa.gov/viewers/bathymetry/ Cool, now I can guesstimate where it was that I clung to a rock/ramp for ten minutes, about 30 minutes into a "late slack" (aka too early start) :crabmode: Scr...

If they are rare, is it wise to collect them for science? What happens to the collected individuals? Can they be alternatively studied in situ? How does one estimate a safe number of collections that will not adversely affect the distribution of a rare population? Can they be easily sexed or aged? A...

I'm on Whidbey often/seasonally and would be interested in some team tec. I rec-tec from shore around here in a few places, just to 45 metres or so normally. B.C. Canada yeah that would be great as soon as we're permitted entry. A 90+ minute dive on some of the wrecks up there would be pretty cool, ...

Price range? I have a set of Faber HP100 doubles with bands, valves, bases, nitrox stickers and manifold (bought together as a set from DGX in 2019). Hydros are 09/18 and visuals were renewed on 08/20. Some normal cosmetic marking where the bands sit. I don't dive them as doubles anymore, just a fan...

Are there any more soft enough tides for Deception Pass this year? I didn't notice any yet. Skyline has your drift potential and is full of species. We got in a bit early this time and I took a (voluntary) ride to 35 metres. It is like a Deception Pass Lite. Consequential and deserving of good timin...

How about a little thought experiment where we put ourselves in the other's shoes. Our country's incompetence, denial and defiance has ruined their whole year as a business Blame whoever you think is responsible for letting USA become the greatest covid nation, thus forcing border closures, and lett...

Why is it hard for them to just continue primary emergency care coverage for rare DCS incidents (e.g. chamber), and leave the whole "we think your age might be a general health risk outside of diving-specific/DCS primary care" up to medicare, etc? As a "young" diver, I would be w...

What a beautiful blend of nature and civilization, on your mystical weekday morning! I took a dip there on Tuesday, entering 20 minutes before the NOAA 18ft slack prediction.. and it was already slack by then, due to the weaker flood(?) But no dramas. I won't re-post the light-edged ribbon worm pic(...

Just to nerd out about canisters a bit further, In this paper , they put Simon Mitchell on an exercise bike, generating a standardized 2.0 L/min of CO2, with a breathing rate of 44 L/min (22 breaths per minute--quite high for sustained breathing). His 2.64kg (avg.) of sofnolime lasted 202 minutes (a...

Amazing, truly a small lens back in time, and into the parallel planet in which humans remained in ecological balance!
And I bet the enclosed waters were often clearer--even this clear--as well

If you are pushing a 5.5 pd scrubber 6 hours in our colder waters, you are a greater risk taker than me. Our Megs are rated at 3.5 hours, I push to 4, maybe 4.5 if all scooter dives. My understanding is that before CE, cave divers were going with a rough "one hour per pound" rule of thumb...

For example if I suspected a packed canister of being potentially stale, I might be more conservative on the duration and conditions of use, such as the type of dive, and/or dump it more often. Presumably a margin of variation is acceptable for shallower shore dives with low workload and low likelih...

It'd be a shame for good material to go to waste if the hydrate is still functionally intact. More of a shame though if misused with poor outcome, yes. Sounds like a highly advanced consideration for someone who is confident in their abilities to judge risks, efficacy and appropriate use circumstanc...

Were you (original poster) dealing directly with GP yourself? Or was this a booking through a third party (shop or organizer)? I could imagine a resort telling a shop that their group booking slot & deposit has been bumped ahead...please understand, etc etc In those cases however, the shop/organ...

Ok thanks I am interested given they have a stated shelf life of 5 years. That is if nobody else needs them soon, like by the end of week/month. I don't want to be a hoarder since I still have a full unopened keg

I've experienced them, on either side of the actual slack--which I would define as the time, however brief, when they are not strongly in effect in the typical diving area. Then again I have only gone when the predicted max currents on either side of the switch are less than ~3.5kt.

I've been focusing on hitting Deception Pass, Skyline and Keystone off slack to work on skills Wait. You've been diving them off slack ?? I'm hoping to do a long weekend shore dive trip to hit Salt Creek, Seiku and some other random sites out on the peninsula. A camp/dive trip to Salt Creek or Lake...

Can I tag along and will there be CCRs involved

Is this the same Sofnolime 797 CO2 Absorbent 8-12 Mesh Granules, Non-Indicating (44 lb | 20 kg) that are found online for $150/single keg? I am working to the bottom of one and have another unopened but this sounds like a good deal Sofnolime 797. Thanks I was asking that to confirm mesh size, non-i...

Wow, thanks! Quite the novelty for company among the lovely pebbles!

What's this thing? Seen swimming near the surface at North Beach (from videocapture)

Did I just seen an 8 metre safety stop?
