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.

Short summary
The Iberia–Biscay–Ireland region in the North Atlantic has diverse ocean currents impacting upper and deeper layers. These currents are vital for heat transport, species dispersion, and sediment and pollutant movement. Monitoring them is crucial for informed decision-making in ocean-related activities, including the blue economy sector. This study introduces an indicator to track these currents, covering main ones like the Azores, Canary, Portugal, and poleward slope currents.

Short summary
The Mediterranean Outflow Water (MOW) is a dense water mass originated in the Gibraltar Straight. The CMEMS IBI ocean reanalysis is used to provide a detailed view of the circulation and mixing processes of MOW near the Iberian and African Continental slopes. This work emphasizes the relevance of the complex bathymetric features defining the circulation and variability processes of MOW in this region.

This paper highlight the adjustment of the wave physics in order to improve the surface stress and thus the ocean/wave coupling dedicated to Iberian Biscay and Ireland domain. The validation with altimeters wave data during the year 2014 has shown a slight improvement of the significant wave height. Statistical analysis of the results of the new and old versions of the wave model MFWAM is examined for the three main ocean regions of the IBI domain.

Short summary
This work highlights the relevance of coupling wave model with ocean model in order to improve key surface ocean parameters and in general to better describe the ocean circulation at small and large scale.
The results focus on the Iberian Biscay and Ireland ocean region with fine grid resolution of 2.5 km for the ocean model. The main conclusion is the improvement of wave physics induces a better ocean mixing at the upper layer and a positive impact for sea surface height in storm events.

Short summary
The article comprises the analysis of the ocean heat content in the northeastern Atlantic Iberian–Biscay–Ireland (IBI) region. The variability of ocean heat content is studied, and results are linked with the variability of the main water masses found in the region. Results show how the coupled interannual variability of water masses accounts for an important part of the total ocean heat content variability in the region.
