Riley's (1946) observation/theory of phytoplankton concentration

Source: R/riley.R

riley is a list holding information relating to Riley's (1946) observation and theory of phytoplankton concentration, used in Chapter 4 of Kelley (2018).

Details

The elements of riley are as follows.

  • 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.

  • 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 (from Riley's (1946) appendix) 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.
