[SST] (Sea surface tempera-
ture): This data layer shows
the temperature of the sea
surface in shades. Lower tem-
peratures are in dark blue,
higher in red.
On the screen, you can turn
on or off the automatic SST
scale by tapping [A].
Set the minimum or maximum
value for which to show SST.
See page 3-5 for how to set
the value. This is available
when [Auto] is off.
[Currents]: The current fore-
cast displays the tidal current speed
and direction by blue arrow. The
darker the blue, the faster the cur-
rent speed (0 to 2 kn).
[Altimetry]: The altimetry forecast
displays the sea height anomalies
by color. The large anomalies are
displayed in red, smaller ones in
light green.
[Plankton]: The plankton forecast
displays the plankton growth in
tones of green. The darker the
green, the greater the density of the
plankton.
