Explore a Detailed Model of the Earth's Oceans
Discover how salinity of seawater deviates at different depths from its standard average value of 35.2 g/kg.
Compute an array of values of salinity anomaly along the 180° E meridian for depths ranging from 0 to 6000 meters, and assuming a constant temperature of 15 °C.

{lat, -85, 65, 5}, {d, 0, 6000, 50}];
The highest deviations are found for larger latitudes.
