Chlorophyll a measured monthly or bi-weekly in the Zeeschelde at 16 stations, independently of the tidal phase and spring/neap cycle. meer
Bucket samples at the water surface were taken once or twice a month at each station to estimate the chlorophyll a concentration. To determine the chlorophyll a concentration (in the presence of pheophytin pigments), we followed the spectrophotometric method described in Rice et al. (2017) using 50 ml water samples, a 1-cm pathway cuvette, and a Shimadzu UV-1700 spectrophotometer. We corrected for pheophytin pigment by replacing the '11.85(OD664)' term in Rice et al. (2017) with the product of the 26.7 absorbance correctio n factor and the corresponding subtraction of the optical densities OD664 and OD665 before and after acidification, respectively.

Chlorofyl a Methode
Chlorofyl a: Spectrophotometry (Rice et al. (2017)) To estimate the chlorophyll a concentration, we used the spectrophotometric method described in Rice et al. (2017) that corrects for turbidity, chlorophyll b, chlorophyll c, and pheophytin pigments. We used 50 ml water samples, a 1-cm pathway cuvette, and a Shimadzu UV-1700 spectrophotometer. We corrected for pheophytin pigment by replacing the '11.85(OD664)' term in Rice et al.
