Table S1.
Sensitivity of alarms to window length for phycocyanin
| Window length (days) | SD first alarm (DOY) | SD alarms prior DOY 180 (no.) | AC first alarm (DOY) | AC alarms before DOY 180 (no.) |
| 13 | 171 | 3 | 191 | 0 |
| 18 | 166 | 4 | 163 | 2 |
| 23 | 165 | 4 | 163 | 2 |
| 28 | 165 | 5 | 163 | 3 |
| 33 | 167 | 4 | 164 | 4 |
| 38 | 170 | 4 | 172 | 2 |
| 43 | 174 | 2 | 175 | 3 |
SD and AC were calculated for 5-d interval windows bracketing the 28-d window used in the study. Results are the day of year (DOY) of the first alarm and the number of alarms prior the nutrient halt on day of year (DOY) 180.
