Year-round spatiotemporal distribution of harbour porpoises within and around the Maryland wind energy area
Fig 4
The mean number of minutes in each hour that harbour porpoises were detected at sites 1 and 2, where the hour of the day was a significant factor in the generalized auto-regressive moving average (GARMA) models of hourly porpoise presence.
The shaded polygons represent the standard error.
