wilson: Wilson's (1963) table of seafloor spreading

Description

wilson holds Wilson's (1963) table of seafloor spreading, extracted from his Table 1, taking only the first 3 columns, and only those rows for which Wilson reported an estimate of spreading rate. This dataset was used in Chapter 4 of Kelley (2018).

Usage

data(wilson, package="ocedata")

Examples

data(wilson, package="ocedata")
plot(wilson$Age, wilson$Distance, xlab="Age [My]", ylab="Distance [km]",
    xlim=c(125,0), ylim=c(0,4000))
abline(0,4000/125)
m <- lm(Distance~Age-1, data=wilson)
# Wilson reports in cm/year; 1cm/y = 1km/1My * 1e5 / 1e6
spreadingRate <- as.numeric(coef(m)) / 10
print(spreadingRate)
abline(m, col=2)
