concentration measures in several years (different symbols) at 59°N, 19°W in the
Norwegian Sea compared with field time-series data (points)
(^) (After Hurtt & Armstrong 1999).
(^) The second shows the output of a modestly elaborate pelagic ecosystem model
intended to represent the seasonal cycling of phytoplankton stocks. That is really just
a function which issues one value of the quantity of phytoplankton for each set of
system variables provided to it, including previous stock abundance. We will examine
several such models in some detail. Hurtt and Armstrong were satisfied with this
result, which does pass through the central tendency of the actual data from the
model. Sometimes the best we can do in biological oceanography is to find rough
approximations.
