[anecdotally, I have experienced this scuba diving in a drysuit in WA and BC, especially in freshwater, so it is wonderful to see some background]

We've turned on the magic algae lamp just for you today. A little romance is a must!
Throw away your lava lamps! This one is all the rage now

Just posted my February wrap-up of dives. It's a short one since I only managed two dives that month, but I did get some interesting photos.
What I like about diving are these unexpected moments.
Our local lake. Been there hundreds of times. You think to yourself, nothing special.
And then you experience this special light mood, this abundance of color. The shore is flooded. Just below the surface, you get unexpected insights into the beauty of nature. The good things are often so close.
This moment, captured in the fall of 2024.

Looks deadly boring?
Yes, on the surface! But take a look at what can be hidden underneath...

IRL this is really large, 2.5 m square, I love big paintings, someday I'd like to do that. Cool color and textures and variety, seems like a positive celebration of life under the sea, diversity, adventure.
I was listening to a podcast about kelp forest and purple sea urchins yesterday. The woman was comparing underwater climate change to forest fires that we can't see, I thought that was interesting.

Cave diving in France
One of our favorite region for diving is the Lot region in #France. The picture shows @tinca_tinca in the beautiful cave Cunhac, for some divers also known as 'Ressel 2'. It is quite small cave, a few hundred meters long and 45m deep. But nonetheless it is always worth a dive. Especially if the visibility is good.
From a diver's perspective
This is the entrance area of the #CuevaDelAgua an underwater #cave. The view upwards shows you an impressive ceiling. It somehow reminds you of stalactites. But this cave wasn't dry long enough for that. You think about how the water has created this work of art over thousands of years...
What will you discover around the next corner?
