how to define global coastline shapefile (boundary line) for a pcolor plot of data having range from 0 to 360 instead of -180 to 180

Hello all,

I was juts doing some seasurface temperature plots which has the range longitude from 0 to 360, the sample plot and data set(a single year data file is shared since the entire data set is too large to share) is attached below.

I would like highlight the coastline for this plot, which i wasnt able to do.
