Opportunistic real-world evaluation of instrumentation performance and stability

A deep ocean instrumented lander was placed on the ocean floor in Drake Passage however after a four-year deployment it was not able to be recovered. Seven years later this lander was found on a beach 14,000 km to the east. Two of the sensors mounted on the lander were found to be functional and wer...

Description
Summary:A deep ocean instrumented lander was placed on the ocean floor in Drake Passage however after a four-year deployment it was not able to be recovered. Seven years later this lander was found on a beach 14,000 km to the east. Two of the sensors mounted on the lander were found to be functional and were able to be recalibrated. These recalibrations enabled quantification of the sensor stability for this period. These results are compared to the manufacturer's claimed performance figures, which were found to be realistic.
