S3 Fig -

a) “Lollipop” plot showing marine heat waves (represented by maximum intensities) for Wellington (see S2 Fig). Dashed line indicates the MHW intensity chosen for this experiment (2.7°C). b) Local climatology for Wellington for the period between 1^st Jan. 2017 and 1^st Jan. 2019. Solid grey line indicates the long-term mean. Temperatures above the 90% climatological average (solid green line) that persisted for over 5 days (= MHW) are highlighted in red. Dashed grey lines indicate the ambient temperature selected (~16°C) for this experiment that usually occurs at the time of collection in March (NZ late summer/early autumn). Both plots were created using satellite derived daily sea surface temperatures from 1^st Jan. 1982 to 31^st Dec. 2020 and the R package “heatwaveR”.
