fully covering the measurement area, the instrument did not experience an instrument
failure but rather inability to measure due to environmental conditions.
Kaneohe Bay, HI Field Test Results: After the first month of deployment, the instrument
stopped recording data. Further analysis at the In-Situ factory showed moisture ingress that
is believed to have caused the instrument failure.
Profiling Evaluation: The high and low offsets observed with profiling evaluation are
believed to be caused by instability of the instrument temperature sensor, dissolved oxygen
sensor or a combination of both. After full stabilization, the dissolved oxygen values better
aligned with the reference instrument.
For awareness, the TROLL 9500 is a legacy product for us. The innovative scientists at In-
Situ have launched a replacement for the TROLL 9500 which is engineered for better
reliability and accuracy in harsh environmental conditions.
We are grateful to the Alliance for Coastal Technologies for inviting us to participate in this
study. The field and lab data collected and reported have provided us with an opportunity
to improve upon our product offering, training and testing procedures. We look forward
with great anticipation to participating in future studies with your organizations.
Respectfully,
