On Plankton, Warming and Whiplash

My thoughts on this issue are mostly consistent with those expressed by Falkowski and Antoine below. Boyce et al. should be complimented for their effort to address a pressing issue and for their use of a historical data set, but the main finding of their paper is not robust. Mackas and Dunne and I noted the significant bias between the Secchi disk method and in situ fluorometry which, when combined with a shift from one sampling technique to the other during the 1900s, induced a spurious centennial scale trend in the data. This emphasizes the importance of consistent measurement techniques (or a well understood calibration between similar techniques) when investigating long-term trends. A precious few observational programs have made sampling consistency a priority during the last several decades; these programs were noted by McQuatters-Gollop et al. in their comment. So ...
