- Statement
- We used 7,114 profiles from 56 floats (Figure 1), spanning 2012-2021. Bloom phenology was calculated using bulk chl ([chl]), bulk Cphyto ([Cphyto]) and mean NO3 (Figure 2). The rate of change was defined as: r=(1/P)(dP/dt) based on Llort et al. (2015), where P is [chl], [Cphyto] or mean NO3. Each of these parameters was used to define the onset, climax and apex of the bloom. The onset corresponds to the minimum of the bulk variable before it increases, when the rate of change (r)=0. The climax is when the maximum value of r occurs, and the apex is when the maximum value of the bulk variable co-occurs with r=0 (Behrenfeld and Boss 2018; Uchida et al. 2019). For the bloom period for each year, a minimum of 11 months was considered, from June to April (inclusive). Floats/years with <11 months were not used in the analysis. To avoid including years with big data gaps, bloom periods with >1 missing profile were not included.
