Riley's (1946) observation and theory of phytoplankton
concentration. The list
riley contains three entries.
riley$fig21points is a data frame representing the data shown in Riley's Figure
21. Resulting from digitization of his graph, this is a list containing
day (day in
P (phytoplankton concentraiton, in grams of Carbon per square meter.
riley$fig21curve is a data frame with columns named
containing a digitized trace of the curve with which Riley illustrates his numerical
solution of the differential equations for phytoplankton growth.
DEparameters is a list containing data about twice per month, in elements
day for the day of the year,
Ph for phytoplankton growth rate,
phytoplankton respiration rate, and
G for the rate at which zooplankton graze on
phytoplankton. The rates are in inverse days.
This is used in Chapter 4 of .
riley$fig21points is based on manual manual digitization of
Riley's Figure 21.
riley$fig21curve are based on manual
digitization of Riley's theoretical curve in the same figure, fitted to a
splinefun, which yields a function that can be
used to predict at any time.
