tempsalinity {UsingR} | R Documentation

## Temperature/Salinity measurements along a moving Eddy

### 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 http://www.toptotop.org/climate/psu.php).

### 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)))
      }
