The mixed-layer depth in the Ocean Model Intercomparison Project (OMIP):...
The ocean mixed layer is the interface between the ocean interior and the atmosphere or sea ice and plays a key role in climate variability. It is thus critical that numerical...- publication PDF

Impact of volcanic eruptions on CMIP6 decadal predictions: A multi-model analysis
In recent decades, three major volcanic eruptions of different intensity have occurred (Mount Agung in 1963, El Chich oacute;n in 1982 and Mount Pinatubo in 1991), with reported...- publication PDF
