riley: Riley's (1946) observation and theory of phytoplankton concentration

Description

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 concentration, 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].
