ON THE CHLOROPHYLL-A RETENTION PROPERTIES OF GLASS-FIBER GF/F FILTERS Academic Article uri icon

abstract

  • Extensive comparisons of the retention properties of glassfiber GF/F and 0.2m membrane filters show that these two filter types retain equivalent amounts of Chl a. The experiments conducted were in the open ocean waters of the Pacific Ocean, from 46N to 28S, including waters from the equatorial divergence, the low latitude subtropical gyres, and higher latitudes. These results contradict a recent report that suggests that in some cases GF/F filters underestimate chlorophyll concentration by 4fold when compared with 0.2m membrane filters. The data set also allowed examination of latitudinal gradients in integrated chlorophyll. Previously observed latitudinal gradients in the North Pacific were present but were much weaker than those found in the South Pacific.
