First, we corrected past data for known biases in measurements
We know the water passed through warm engine rooms, that's fine. It is those bloody buoys that measure the temperature directly that have to be adjusted for "cooling bias".
"The 2015 analysis showed that the modern buoys now used to measure ocean temperatures tend to report slightly cooler temperatures than older ship-based systems, even when measuring the same part of the ocean at the same time. As buoy measurements have replaced ship measurements, this had hidden some of the real-world warming.
After correcting for this
“cold bias,” researchers with the National Oceanic and Atmospheric Administration concluded in the journal Science that the oceans have actually warmed 0.12 degrees"
"however, ships began to automatically measure water piped through the engine room, which typically is warm. Nowadays, buoys cover much of the ocean and that data is beginning to supplant ship data. But the buoys
report slightly cooler temperatures because they measure water directly from the ocean instead of after a trip through a warm engine room."
