Temperature/Salinity measurements along a moving Eddy

Share:

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

1

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.

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