Data from: Behavioural responses of Atlantic cod to sea temperature changes
Understanding responses of marine species to temperature variability is essential to predict impacts of future climate change in the oceans. Most ectotherms are expected to adjust their behavior to avoid extreme temperatures and minimize acute changes in body temperature. However, measuring such beh...

Understanding responses of marine species to temperature variability is essential to predict impacts of future climate change in the oceans.
