Things of beauty!

Very last minute. It's such a beautiful day I would love to get out for a dive. Currents in PT are sucky although we could probably do a bottle hunting dive in town near the ferry terminal. Or Pt Whitney near Brinnon. Or the Gardiner boat launch. I just want to blow bubbles! Maybe meet somewhere at ...

Dove Pt Hudson yesterday... never seen so much destruction under the water. Lots of debris, leaves, wood, kelp, trash. The eel grass beds were missing or mostly destroyed. Many metridium anemones and monster barnacles gone. Just a mess. :-(

It will depend on a ton of other variables (for aquatic life) because lead competes with ions like calcium and magnesium on gill surfaces - the resulting ionic imbalance is what causes toxicity (at a very high level). Since many of the lead salts appear insoluble, or at least not-very-soluble, I'd ...

The surface passivation of metallic lead in water is a mixture of lead salts including Cl-, OH- and SO4-. https://www.tandfonline.com/doi/abs/10.1179/000705982798274480?journalCode=ycst19 The high surface area along with the grinding of the pellets in the bag together afterwards is leading that pas...

Cheaper alternative: Bismuth.

Or use coated lead.

There's gotta be a chemist in this group with some more info on what the milky stuff is. That residue is almost certainly lead oxide. Lead naturally forms a thin oxide layer, a dull grey coating which often stays intact on solid weights. The trouble with shot weights is that the shot grinds against...

I see that milky residue all the time. It's why I wash my weights last, so the reg isn't contaminated.

Depleted uranium would work even better.

I'm not defending them, but they did post a response to ScubaGadget's FaceBook post on the matter: " Seasoft Scuba Hey, you can believe what you read or you can see what we have done over 35 years. We have been fined for spilling the equivalence of about 1 lb. of lead. Give us a little time to ...

Just grousin'. Harumph.

Interesting. I used Zodiacs for years and never had a problem, but that was the super-expensive mil-pro series.

What brands do you think are near the top?

Well cool! I hadn't heard of them. No idea if of the quality but the inflatable prices are pretty good, on par with Zodiac or a bit cheaper.

Now oxygen dead zones are happening here.

Coastal Pacific Oxygen Levels Now Plummet Once A Year

Was dithering on whether to dive today, it being rainy and mucky out. Glad I went!

Found a German (?) stoneware mineral water jug. 1880's? The first one I've seen come out of the bay here. Wow!

Whoa, blob tops! I love 'em. Nice collection.

Hood Canal (Triton Cove and Point Whitney), lentil soup to 20' deep, opening up below with 25-30ft of vis.

From Monday's dive (#799!)

Two Washington Territory medicine bottles in perfect condition. "N.D. Hill & Sons Druggists Port Townsend, W.T."

Washington became a state in 1889, so these have been sitting on the ocean bottom since before then. Waiting for me!

Is harvesting an illegally dumped invasive species from a protected park illegal?

Let's find out!

Hang in there Rich!

Well this is fun! Found in Townsend Bay this past weekend...

Franklin Hart Remedy Co, New York. Circa 1880, "FLORAPLEXION cures Dyspepsia Liver Complaint and Consumption". Wow! A panacea.
