Short summary

In this research we analyzed the marine heat waves (MHWs) that occurred in the IBI domain during the year 2022. Also, we shed light on the first steps of learning how MHWs behave under the ocean surface through the 2022 Bay of Biscay events. Our results show at least two extreme MHW events for the Bay of Biscay and the Celtic Sea for the year 2022. Moreover, we found that there is a seasonal modulation in mean MHW depth for the Bay of Biscay.
