Riley's (1946) observation and theory of phytoplankton
concentration. The list riley
contains three entries.
riley$fig21points
is a data frame representing the data shown in Riley's Figure
21. Resulting from digitization of his graph, this is a list containing day
(day in
year) and P
(phytoplankton concentraiton, in grams of Carbon per square meter.
riley$fig21curve
is a data frame with columns named day
and P
,
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, R
for
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 [1].

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
spline with splinefun
, which yields a function that can be
used to predict at any time. riley$DEparameters
was transcribed from
Riley's appendix.
