In Jan/Feb I spent two weeks back in Bariloche with Esteban and Beatriz and their lab. As usual it was quite a nice trip, made nicer by the fact the volcano had stopped, the air was clear, the lakes were free of ash, and the airport was open! Below is a view of the glacial arm of Lake Mascardi, where the suspended glacial powder shades the water column, lowers the seston C:P ratio, and makes life better for Daphnia! (according to the beautiful research of Cecilia Laspoumaderes)
Spent the past week here in Manizales, Colombia, with Jorge Bueno, the very impressive director of the Colombia Instituto de Astrobiologia. Gave a couple of talks at Univ of Caldas (nice place!), got interviewed about astrobiology on local TV (live! in Spanish!), and visited the volcano twice with various students and scientists. The clouds behind me is the volcano emitting ash and the hot spring has temperature of 70° C and pH of 1.3. There are very good research possibilities up there.

I had overlooked it but the article that was written about our NASA- & NSF-funded work on “life on floating pumice” is out in Astrobiology Magazine. Have a look. LINK
We’ve arrived to Cuatro Cienegas after a comfortably uneventful trip from Monterey. At the moment it’s me (Jim), Jess, Zarraz, and Alex. We spent the first two days scrambling around and setting things up. The UNAM crowd arrived yesterday. Of course, our main work is at Churince and Jim’s Pond has enough water in it to get started. We did our first sampling and will begin the fertilization this weekend. The usual complications with permits is underway and at the moment we are “closed out” of working at my favorite place, Rio Mesquites. This is a bit of a problem for Jess, who is trying to finish her PhD studies. However, we have permission to work “upstream”, in Mojarral East and its outflow stream. We had a spectacular scouting trip there today. See picture below.

I finally found some time to pull together the video I shot during our trek in Torres del Paine National Park (Chile). Have a look. It’s HD! LINK
Our time in Bariloche was (sadly) over and we packed up all our things and said goodbye for now to the wonderful Laboratorio Limnologia. Since our flight back was out of Puerto Montt, Chile (a ticket bought before the Bariloche airport had re-opened), we decided to cross into Chile in style, via the Cruce Andino (“Andean Crossing”). So, Esteban dropped us at the pier at Puerto Pañuelo near Llao Llao, where we boarded a catamaran. It was a gorgeous day and after a couple of hours we reached the western end of Lake Nahuel Huapi in the rainforests of Puerto Blest (3600 mm of rain a year!). We disembarked and headed by a short bus trip to Lago Frias, a cool-looking lake all turbid with glacial flour. Mt Tronador loomed overhead. After a short trip on the lake we landed on the far side and passed through Argentinian customs to file our departure card. Then, into another bus for about a 60-min ride, crossing the Argentina/Chile border to the tiny town of Peulla on Lago Todos de Santos. Here we had to clear Chilean immigration. Most of the passengers continued on the rest of the way but we booked two nights to stay in this little town. We enjoyed walking around, sleeping late, and working our way through the hotel restaurant’s limited menu. A highlight was seeing a Chilean pygmy owl sitting on a wire with a hummingbird! The weather both these days was sunny and hot – highly unusual! On the last day we rejoined the crossing, boarding the boat to cross L. Todos de Santos. This is a spectacular lake with many large mountains all around and waterfalls and deep forests. Unfortunately the weather was shaky with low clouds and we did not get to experience the astonishing view of the Osorno volcano for which this part of the trip is famous. After several hours of cruising we arrived at the landing at Petrohue (where we had been previously, during our November trip to Chile) where a bus completed the crossing, taking us in a intensifying, Chile-style, rain to our favorite little town of Puerto Varas. We immediately headed off to La Olla for a final seafood feast then to bed to rest before the long flight home. Pics HERE. Everytrail map showing the route, plus more pics, is below.
Adios Patagonia! Que triste!
Adios a Argentina! (Desde Lago Todos de Santos)
We enjoyed a beautiful sunrise in P Natales and picked up our rental van to head south to Punta Arenas. We took a side road and enjoyed some great scenery that included lots of geese and an intriguing sculpture in the middle of nowhere that evoked either a giant squid or a baleen whale or something else. We stopped at the Magellanic penguin colony at Seno Otway and enjoyed the hijinks of the penguins as they sheltered on the beach. The colony was in the life cycle stage where the young were making their first trips to sea. So we only saw about 50 penguins of the 10,000 that are reportedly at this colony – the rest were busy chasing fish. But it was fun (and, of course, windy!).
After a night in gray and semi-depressing P Arenas, we met our guide for the next day who would take us, at our request, to Tierra del Fuego on another penguin quest. Being Monday, the regular (long) ferry to Tierra del Fuego was not operating so we had to drive east about 2 to to take a shorter ferry across. After the very windy but short (20 min) crossing, we spent a couple of hours of driving across the pampas (which featured guanaco and rheas and, of course, a large number of sheep. We stopped for a while to watch a “huaso” (NOT a “gaucho”, those are in ARGENTINA) work with his dogs to move a big herd of sheep into a new pasture.)
Eventually we arrived at our destination: Bahia Inutil and its very unusual colony of King Penguins. These gorgeous penguins normally inhabit oceanic islands, being found by the 100’s of thousands on South Georgia Island, the Malvinas (aka “Falklands”), etc. But, for unknown reasons, some set up shop at this wind-swept beach about 15 years ago. A small “preserve” was set up (the area is fenced and a guard stays there more or less full-time), creating a new destination for eco-tourism out of P. Arenas. Unfortunately, our guide didn’t know that the preserve was closed on Mondays! After some negotiating, the owner was summoned and she was very friendly and eager to meet us (our connections to biology, Science magazine, and National Geographic didn’t hurt, especially the latter). So, we got a “private tour” and enjoyed the 17 or so penguins who were hanging out (the entire colony is about 75 or so; the rest were out fishing). The group included a few chicks, being “tended” (sat on) by males and females alike and peeking out from underneath for an occasional snack. After an hour or so we started the long trip back, highlighted by the tiny (~5 feet?) black and white Commerson’s dolphins that played in the bow wave of the ferry. One more night of seafood and pisco sours and our time in Chile had ended. But a final thrill awaited: a view from above of Torres del Paine as we flew out and then, minutes later, a view of spectacular Mt Fitzroy (in Argentina), perhaps enticing us back for another trek?
