A Commercial Extract of Brown Macroalga (Ascophyllum nodosum) Affects Yield and the Nutritional Quality of Spinach In Vitro (2013, methodology): “The total chlorophyll content was calculated according to Ritchie (2008).”
Responses of marine benthic microalgae to elevated CO2 (2011, positive): “The absorbance of each sample at 632, 649, 665, 696 and 750 nm was measured using a Cecil CE2011 spectrophotometer, and the concentration of the total chlorophyll a (chl a ) in the sample ( l g cm - 2 ) was calculated using the quadrichroic equation of Ritchie (2008).”
Warmer more acidic conditions cause decreased productivity and calcification in subtropical coral reef sediment‐dwelling calcifiers (2011, methodology): “…centrifuged at 1500 3 g for 10 min; the supernatant was placed into a quartz cuvette in a spectrophotometer (Varian); and absorbance was measured at 630, 647, and 664 nm. Chlorophyll concentrations were determined using the equations of Ritchie (2008), and the results were expressed in mg mm22.”
Mechanisms of Thermal Tolerance in Reef-Building Corals across a Fine-Grained Environmental Mosaic: Lessons from Ofu, American Samoa (2018, methodology): “…subsequent days of incubation at 29◦C. Heated branches are then compared to branches from the same colonies from control tanks, visually scored on a 1–5 scale (Seneca and Palumbi, 2015; Rose et al., 2016), and placed in 3ml of 95% ethanol for chlorophyll spectrophotometric analyses (Ritchie, 2008).”
Extraction of chlorophyll a from biological soil crusts: A comparison of solvents for spectrophotometric determination (2011, background): “Past studies have noted that hot ethanol preparations have high chla extraction efficiencies for organisms that are difficult to extract (Ritchie, 2008), which is supported by this study and the finding that ethanol was one of the more efficient solvents tested here.”
