The trip to Grímsstaðir was successful, even though Konrad in the cold 10 m/s north wind of 4 °C could only shortly put his healing hands on the station. At first, it was not clear what caused the malfunction, but leaving the station working behind us, we travel towards Reykjavík. A data analysis in the night then reveals the problem – overheating, what a surprise! The sun and nearly 20 °C managed to raise the OPC inside temperature to 57 °C, forcing the system into a safety shutdown. So on the next trip, we need to bring some shade. Meanwhile, a temperature-controlled temporary laser shutdown needs to do the trick.
Back in Reykjavík, we try to turn the moose into an elephant by adding a trunk for deep waters, before we head home for a short vacation. Stay tuned for vol. III in August…
