Day 5 - IVER Mission Planning

After the experiments of the day before, including a full grid run at the surface, we decided to make the mission grid a little smaller. This was done to keep the IVER farther away from the shore and minimize the risk to the IVER. We set the IVER to undulate between the surface and 10 meters (30 feet) or 12.192 meters (40 feet) in order to gather dissolved oxygen data as deep as possible. This was the most ambitious mission that our IVER has been sent on yet in terms of depth! And it performed admirably each time! The OceanServer software predicted that the mission would last 50 minutes, but it turned out to last about 65 minutes each time it was completed.

Today's testing was very successful, but didn't come without a little excitement. In the middle of a mission the head of the field station came speeding down in his car to our test site and shouted to Kasper in Norwegian. While none of us understood what was being communicated, Kasper definitely did, as he took off running towards the field station. As we came to find out later, Kasper's lab experiment unfortunately got a little hot, as the projector being used to provide light to the water samples overheated and began smoking. This was an unfortunate setback but KAsper, as usual, carried on with his cheerful and kind attitude. Below is a picture of the experiment...before the accident.

During the next mission we were able to escape for quick hike up the closest mountain. All of us had been eager to hike, and we finally got the change. Fifteen minutes later we found ourselves at the top with a spectacular view of the bay and the Trondheim fjord. Below are some of the pictures taken.

When we returned we found Jane looking comfy on our local rock. A good book, beautiful view, and comfortable rock....who could ask for more!

After Jane...thats right Jane.... sent the IVER out on its last mission we finally decided to walk the walk after talking the talk....and go for a swim. We knew it would be cold, but as we said "How many times to you get the chance to swim in Norwegian fjord!?" It ended up being Jesse, Kevin, and Frank in the initial group. We made it look so good that Chris couldn't help but follow our lead minutes later. The water was definitely a bit chilly, but once you got used to it (AKA body went numb), all of the chill went away and the fun began. We had swim races, did flips and dives off the dock, and provided our best impersonations of the IVER itself.

Overall we had a great last day of testing. We took some great data that demonstrated fluctuating O2 levels based on the reading. Also the sun came out, the rain stopped, and we were blessed with a truly gorgeous Norwegian day.
