Description
Chlorophyll a measured monthly or bi-weekly in the Zeeschelde at 16 stations, independently of the tidal phase and spring/neap cycle. more

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.

Chlorophyll 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. (2017) with the product of the 26.7 absorbance correction factor and the corresponding subtraction of the optical dens
