_D_e_s_c_r_i_p_t_i_o_n:

     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.

_U_s_a_g_e:

     data(tempsalinity)

_F_o_r_m_a_t:

     The data is stored as multivariate zooreg object with variables
     longitude, latitude, temperature (Celsius), and salinity (psu -
     practical salinity units <URL:
     http://www.toptotop.org/climate/psu.php>).

_D_e_t_a_i_l_s:

     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.

_S_o_u_r_c_e:

     Data from simulation by Andrew Poje.

_E_x_a_m_p_l_e_s:

     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)))
       }
