Assembling our lawn-mower

A few days have gone since we arrived in Chile. After some delay, our last bits of equipment finally arrived at CIEP (Centro de Investigación en Ecosistemas de la Patagonia), the institute of our collaborators in Coyhaique. Although this was a major step forward, our final destination, Caleta Tortel, was still 500 km away. In the…

Austral winter lawn-mowing

Seven months have passed since the last field expedition in January, so it is time for us to head back and continue our GLOF adventure. I exchanged my Chilean summer expedition luggage for some warm winter clothing since weather forecasts predict temperatures barely climbing above freezing point. For this expedition, the plan is to map the…

Working 5 to 9

“Tumble out of bed, and stumble to the… platform!” The last couple of days we have been in a working haze. Last week, the new barrel and ground plate finally arrived in Anchorage, so we drove immediately to Anchorage and picked it up. Since we had to leave Cooper landing after the weekend, we basically had a long…

Short coring extravaganza

While we are waiting for the equipment to arrive in Anchorage, we retrieved the left behind anchors and ropes. Also, we collected 19 short cores. Most of them will be used for mapping and analyzing the characteristics of the 1964 megaturbidite in the deep basin. Also some will be used for geotechnical slope stability and…

A not so perfect storm

Last Thursday, we were pulling up a 3m-core when suddenly winds came up, causing dangerously high waves in only half an hour. We secured our equipment and took off with the boat. Friday, the storm reached his peak, creating waves of almost 3 meters! Therefore we could not go on the lake to check our…

The Game of Cores

A few days ago we finished our first coring location. In total we took eight cores of three meters, i.e. 0-2 m, 3-6 m, 7-10 m, 11-14 m and the overlaps 1-4 m, 5-8 m, 9-12 m, 13-16 m. We also collected two short cores. So we retrieved in total 16 meters of sediments. It…

Deep Coring for Dummies

In case we want to core from 0-3 m, which is from the lake bottom down to 3 meters in the sediments below, we will follow the next scenario. First we put down the ground plate with the 3 tubes and funnel attached on top. This installation on the lake bottom (200 m deep) will…
