Does blending of chlorophyll data bias temporal trend?

ABSTRACT Arising from D. G. Boyce, M. R. Lewis & B. Worm _Nature_ 466, 591–596 (2010)10.1038/nature09268; Boyce _et al._ reply Phytoplankton account for about half of global and nearly

all of marine primary productivity; consequently, any widespread drop in phytoplankton biomass would almost certainly have severe ecological consequences. Boyce _et al._1 have reported

strong (∼1% per year) and sustained declines in marine phytoplankton biomass at local, regional and global scales. However, I suggest that some or much of their reported declines are

attributable to bias between the two data types used by Boyce _et al._1. Although real changes may have occurred, their proper quantification requires removal of the bias component. Access
