Water Salinity and River Discharge
salinity data frame has 28 rows and 4 columns.
Biweekly averages of the water salinity and river discharge in Pamlico Sound, North Carolina were recorded between the years 1972 and 1977. The data in this set consists only of those measurements in March, April and May.
This data frame contains the following columns:
The average salinity of the water over two weeks.
The average salinity of the water lagged two weeks. Since only spring is used, the value of
lagis not always equal to the previous value of
A factor indicating in which of the 6 biweekly periods between March and May, the observations were taken. The levels of the factor are from 0 to 5 with 0 being the first two weeks in March.
The amount of river discharge during the two weeks for which
salis the average salinity.
