Temperature/Salinity measurements along a moving Eddy
Simulated measurements of temperature and salinity in the center of 'Eddy Juggernaut', a huge anti-cyclone (clockwise rotating) Loop Current Ring in the Gulf of Mexico. The start date is October 18, 1999.
data(tempsalinity)
The data is stored as multivariate zooreg object with variables longitude, latitude, temperature (Celsius), and salinity (psu - practical salinity units, originally from http://www.toptotop.org/climate).
The temperature salinity profile of body of water can be characteristic. This data shows a change in the profile in time as the eddy accumulates new water.
Data from simulation by Andrew Poje.
data(tempsalinity)
if(require(zoo)) {
plot(tempsalinity[,3:4])
## overide plot.zoo method

abline(lm(salinity ~ temperature, tempsalinity, subset = 1:67))
abline(lm(salinity ~ temperature, tempsalinity, subset = -(1:67)))
