Relax and Recap

Today we got some much needed time to rest and recuperate back at the hostel after camping at the Hotel Husafell campgrounds. Our stream crew sampled four lakes during this three day/ two night outing, including one experiencing bottom drainage, one fed by glacial runoff from Langjokull, a shallow system near Reydarvatn, and a long and thin tectonic lake. Our major achievement was getting not one, but two successful sediment cores! We fought strong winds and swarms of flies to core the lake and extract the sediment for over an hour each time. This will help us to better understand the past condition of these lakes and to see how they have changed over time in temperature and composition. Ridge and stream work was capped off each day with time around the instant grill singing songs about geology and limnology, roasting marshmallows, and telling plenty of scary ghost stories.

We also looked at Ok, a large shield volcano that once had a glacier on top, but has since melted. Don’t worry though, it hasn’t erupted since the Pleistoscene era and is inactive now. In that area, we hiked down a ridge to find our glacial input lake off a steep cliff. It was bright turquoise and stretched along the base of a tuya, or flat-topped volcano. It was also very, very cold! After that, the whole group drove up to and walked on the second largest glacier in Iceland, known as Langjokull, which is Icelandic for “long glacier.” We brought the Dickinson flag along for the photo shoot of course, to fly high in the snow. We definitely felt like we had conquered Iceland. Now it’s time to sit back, relax, and enjoy our day off.  Ya know, the Viking Festival started today… I know what I’m doing this afternoon.

Blown away!

Day 3: Today we took a windy hike to Lake Grænavatn!

After our first productive day in the field, we’ve all been getting into the swing of things and becoming accustomed to our daily routine: wake up, eat a healthy breakfast of Skyr and fish paste from a tube (or not!), load up the vans with equipment, and hit the road. We returned to the lava fields and made our way to the base of a considerably steep ridge in hopes that we could reach Graenavatn on the other side. Despite the relentless wind, one couldn’t have hoped for a more beautiful day in Iceland. It really is breathtaking to see the clear, blue sky over the expanse of green moss and the remnants of lava flows that erupted thousands of years ago.

After a one-mile uphill hike, we arrived at the lake and had a quick lunch consisting of sandwiches, crackers and cheese spread, and chocolate-covered digestive biscuits (a group favorite). Unfortunately, the wind made it impossible to take the boat out and take water chemistry measurements, but thankfully we were still able to collect some water samples and dredge for zooplankton. After we examined the zooplankton under the microscope, we were excited to find a hydra, a type of predatory zooplankton with long tentacles. We named him Daniel!

Hot spring

After our time at the lake, we hiked back to the vans and drove to see some geothermal springs, where boiling sulphuric water bubbles to the earth’s surface. Their magnificence definitely made up for the smell! Think: rotten eggs.

Overall, it was another exciting day full of science and sightseeing. Can’t wait to see where we go next!


Hello from Iceland!

Day 2: Greetings from one of the most beautiful places on Earth!

Today was our first day in the filed, and we started it off with an Icelandic staple: Skyr and granola. After going over some logistics, we journeyed into the vast and astonishingly beautiful lava fields of the Reykjanes Peninsula, in the hopes of scouting out some lakes to sample over the coming weeks. After a bumpy ride and a couple of stops to examine past volcanic activity and extraordinary geological structures, we arrived at Lake Djupavatn, a medium-sized lake surrounded on both sides by steep volcanic rock. A team of four set out to take samples in our raft, while the others explored the lake outlet and surrounding geology. As much as I’d love to go on, the day has been long and we’ll be up early to continue exploring.

We’ll all be updating the blog, so stay tuned!
