I doubt that Halley's, of all comets, would exert enough gravitational pull for oceanic animals to notice. The 1985-6 appearance was disappointing -- I know this because I was a kid eager to see it.

The trouble with books and apps is that neither is particularly waterproof. Especially at depth. So you can't use them in the "field" the way you can, say, a bird guide.

Thank you for the definition. I had heard of bathyscaphes, but I was confused about how they differed from bathyspheres and submersibles. It seems in some ways like the differences between a dirigible, a zeppelin, and a blimp; that is, all similar in concept, but using different buoyancy...

I'm upset and disappointed that my post last week didn't post. Now I'm way out of context. Well, I'm reposting it anyway. This is linguistically interesting. Río and Ría look similar, but they are different words. Río, meaning river, is a fairly well-known Spanish word, as in the Río Grande...

Well, knowing the Greek alphabet, but not the Greek language, I can transliterate but not translate the video title: To kokkino koralli katadush sta 80 metra. I'm guessing that koralli means coral and 80 metra means 80 meters. So if I knew what katadush meant, I would have the gist of it.

Is it because of decompression issues?

Granting "rights" to non-sentient things muddles the meaning of the word rights. However, the sentient beings living in the oceans are another matter; they should have the rights to their homes and to live in peace.

I watch a lot of YouTube videos about snorkeling and freediving, and I have noticed that in several of them, the snorkeler will dive down to a group of scuba divers. Trying to understand how that works, my best guess is that those scuba divers are not going for depth, but for duration -- that...

Reason for suicide: depressed because home ownership was out of reach.

To look at some of the YouTube videos, this seems to be a too-common habit among freedivers, too.

Interesting the theme of naming masks after islands: Ceylon, Bermuda, Ibiza, Madeira, Canaries, and Antilles. Could Majorica have been meant to allude to Mallorca, another of Balearics along with Ibiza? I wonder if there was one named after the Azores? Interestingtly, long before Columbus'...

I used to fit Lorenzoid's description -- a set time on Fabebook every day. But as Facebook changed its fotmat, the problem MiloR mentioned changed that. Now, "sponsored" posts, I understand -- just like our own ScubaBoard forum has ads. But when the "suggested for you" posts proliferated, I...

For many people, this can be a deal breaker. Aren't we told what to do enough at our workplaces? The whole point of hobbies/recreation is to have a break from that. There are so many hobbies that people leave for this very reason. Our sense of the work-to-fun ratio changes over time. But the...

No worries. My Romance-language intercomprehension skills (based on Spanish and Portuguese) came in handy in your threads about Italian manufacturers. I found it interesrting in your list of "Spanish" manufacturers that almost all were either Balearic or Catalan. Catalan, of course, is a rather...

No, actually I pop my ears by doing the Valsalva when driving up a long grade.

That land crab looks similar to one that I saw in French Polynesia -- identified by the iNaturalist community as Cardisoma carnifex.

Pomaranczowe reinded me of a pomeranian. I suppose that some of them do have kind of orange fur.

If you get a cold with a cough, you should assume that you and your entire household will die on a respirator.

But the OP said sweet water.

What's the carbon footprint of splashing with the fins? Does it harm the reef? If we let you splash with your fins, then everyone will want to splash with their fins and it'll just be chaos. :fishslap:
