Resilience indicators before the bloom maximum on day of year 180 for the variables chlorophyll a, phycocyanin, and dissolved oxygen saturation based on detrended time series

Resilience indicator	Chlorophyll	Phycocyanin	Dissolved oxygen saturation
SD positive absolute slope	No	Yes (P < 0.001)	Yes (P < 0.001)
SD positive relative slope	Yes (NS)	Yes (P < 0.001)	Yes (P < 0.001)
SD of first alarm	None	165	167
SD no. of alarms	0	2	3
AC day of first alarm	None	163	None
AC no. of alarms	0	1	0

Rising variance of the indicators was tested by whether the slope of the rolling window SD was positive before the bloom. Both the absolute values and the relative values (manipulated − reference) of the SDs were tested. The day of year of the first alarm and the number of alarms before the bloom maximum (DOY = 180) are also presented for the rolling window SDs and ACs. NS, not significant.
