Volcanic bubbles

  Indonesia: Pulau Weh [Sumatra] - March 2010

Bubble Buddies, here's a little video just for you... I'm taking you to the underwater hot springs of Pulau Weh. Volcanic hot springs, which release a profusion of bubbles, a few meters below the surface !

A Jacuzzi... underwater!

You may have seen such sources on earth, with the characteristic smell of sulfur (it smells like rotten eggs). There are many in the volcanic regions.

Indonesia, located on the famous "belt of fire" of the earth's crust, is in fact a long string of volcanic islands. I remember seeing springs similar to the lake Danau Linownear Manado, in the north of Sulawesi, as well as near Lovina Beach, in the north of Bali.

But underwater, it's much more fun!

From the boat, we can just see big broths on the surface, big packets of bubbles coming up. Moreover, even before seeing them, we already perceive the smell, this funny smell that reminds of chemistry classes and stinky balls ...

Some of the Indonesian guides prefer not to put on their suits for this short dive. They say that the suits are still soaked with it. I'm not very keen on checking the concentration of stinging bugs in the water on my skin, so I kept my 5 mm. But I didn't notice anything special when I rinsed it off, phew!

Water temperature: 33°C

Under water, it is a delight to wallow in the heat of these bubbles that never cease to spring from the bottom, in the middle of crevasses larger or smaller, fringed with a whitish deposit.

The game is to raise as high as possible the thermometer of the dive computer that is on the wrist, placing his hands in front of a large release of hot water and bubbles.

Last record, during our outing on Wednesday: 33°C.

  1. Nice bubbling bath... it makes you want to. 33°? I'm a little disappointed, though. It's lukewarm. 😛 You avoided the nice little egg smell, so much the better. In Iceland, where the springs are hot, even the shower water can have that pleasant little volcanic scent. 😕
    Looking forward to hear and see other bubbles elsewhere.

  2. Not bad as a jaccuzi... Like Marie, I think 33 degrees is not much... 🙄 Outside of these springs, the water is how much?

  3. Ben me I think 33 degrees is not bad ... Especially when I just take a shower almost cold in an IBIS lost alsace ... by less 3 outside ....
    I always read you with so much pleasure !! Thank you thank you! It feels good!
    Good luck! In waiting to read you again !!

  4. Very pleasant story to read, as always.
    I smiled when I read the expression "stink bombs" whose use has become widespread these days in the press given the distressing and nauseating level of the remarks of some politicians during the regional election campaign! 😥
    I am going to go and make my little bubbles in the water of dishes, without smell of sulfur, but pleasantly scented with lemon!

  5. @Married: I think the true temperature was well above 33 ° C. It takes time to get the computers up, and then the hot water mixes with the ambient water, it falsifies the calculations ...
    🙂

    @Malene: Water is at 28 ° C most of the time. Sometimes 29 ° C, sometimes less, in the 24-25 ° C according to some thermoclines.
    😀

    @ Helen: Argh! -3 ° C ... Good if I can send you a little heat!
    🙄

    @ Marie-Julie: Ben me neither. Unprecedented experience!
    🙂

    @Lydie: Oh, there, yes ... it's true that we are in the midst of an election. We should send some of them to sniff those stinky emanations ...
    😆

    @IsaEtMarco: Wouhaaa !!! Thanks for the link, it had to be downright spectacular as a dive. You are giving me ideas for future trips ...
    😈

  6. Smell on the surface ... I knew this by putting myself in the water in one of the blue holes "in land" of the Bahamas, Andros, in preamble to a caving dive. The only difference: even under the water a rotten egg smell goes through the regulator, but fortunately it does not last when you pass the first 2 or 3 meters from the surface.

    But ditto coming out of diving!

    I had told this curious experience:

    And when it comes to bubble diving (!), I tested in Guadeloupe near Basse-Terre, above hot springs. Not really large visible bubbles, but currents of hot water that I enjoyed despite water at 26 ° natural.
    🙂

  7. Dive well, far from our country. Note, spring is coming up today and we will end up putting our hats and gloves down. For the second round of regional, one offers a triangular. Not beautiful life? 8)

  8. No news since March 12 😥 ... did you get lost in your hot tub?? 😛 Well, in the meantime, I'm back to consoling myself with my virtual fishes from the happy Facebook aquarium ❗ 😉

  9. @A World Elsewhere: Yes, I, too, found that even the air of the regulator eventually felt. Thank you for the link, fascinating and singular experience that you lived there ...
    🙄

    @Nono: What would be nice is that spring is well installed when I come back next week ... I am this story of triangular from afar. I will be investigating planes at the time of the results and analyzes ...
    😉

    @Laurence: That's it, I delivered a new ticket ...

    But I am so busy with the dives that I have trouble keeping the blog up to date!
