tempsalinity: Temperature/Salinity measurements along a moving Eddy

In jverzani/UsingR: Data Sets, Etc. for the Text "Using R for Introductory Statistics", Second Edition

Description

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.

Usage

data(tempsalinity)

Format

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).

Details

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.

Source

Data from simulation by Andrew Poje.

Examples

data(tempsalinity)
if(require(zoo)) {
  plot(tempsalinity[,3:4])
  ## overide plot.zoo method
  plot.default(tempsalinity[,3:4])
  abline(lm(salinity ~ temperature, tempsalinity, subset = 1:67))
  abline(lm(salinity ~ temperature, tempsalinity, subset = -(1:67)))
  }
