The dive trip was awesome, for the most part. Though the diving started a little slowly for me, the Revillagigedos definitely lived up to my expectations, and more. I say "for the most part" because in the midst of the great diving, I had some gear related mishaps and some moments of reflection on the way humans treat our oceans. More on both of those topics later as both are very much related to the theme of this blog.

The boat (Nautilus Explorer) was wonderful. It's a large (116 feet), steel liveaboard, and with it's large keel, stabilizing fins, flume tank roll stabilizer and just sheer mass, it rides very well. Fortunately, we didn't put the ride to the test too much as we had nice flat seas for the bulk of the trip. The crew was great, professional and safety conscious. The vessel is Canadian flagged and operates under the aegis of Canadian Transport with the same basic requirements for procedure and safety as a cruise ship. As I mentioned in a previous post, I was onboard as an extra crew member so was able to see some of the behind the scenes safety meetings and processes.
The guests were a nice mix of people from different countries and backgrounds. I had a great time getting to know them, and I think my English accent is getting better. However, my Irish accent "is crap" as guest Derek was kind enough to point out a couple of times. I played an international game of scrabble with a Brit, an Italian and a Netherlander. I did win, but felt pretty stupid in that I barely beat two people for whom English is not only a second language, but one of several second languages.
Las Islas Revillagigedos are a loosely affiliated group of 4 islands about 260 miles southwest of Cabo San Lucas... OK, well, 3 islands and a rock - a wonderful rock. In fact, I think it is now my favorite rock in the entire world. They are claimed by Mexico, which protects them as part of marine reserve system. They are uninhabited, with the exception of a small naval and research facility on Socorro Island. Socorro is the largest of the 4. Depending on what side of the island you view it from, it looks like a volcanic desert or the green coast of Scotland. Clarion Island is much further away and we chose not to visit it on this trip. Some of the endemic species get their name from this island, such as the beautiful Clarion Angelfish and the Clarion Damselfish.
San Benedicto Island is almost completely covered with ash (from a 1952 eruption) with lava flows extending out into the sea. There is so much ash that visibility can suffer when there is a large surge, though fortunately that was not a problem on our trip. Even so, we did have to flush the ash out of the water purification system.

Finally, Roca Partida is a rock sticking up out of the ocean about 60 miles to the west of Socorro. It is the remnants of the plug of an ancient volcano that rests on the shoulders of the rest of the volcano, the top of which sit at about 230 feet and which then plunge down to about 10000 feet.
