Sigma-t is the oceanographer's short-hand for the density of seawater. It is defined as (density - 1.0) × 103. If the density of seawater is 1.02925g/cm³, the sigma-t value is A) 25.29. B) 2.9925. C) 0.2925. D) 29.25. E) 0.02529.

To calculate sigma-t, we first need to subtract 1 from the density of seawater:
density - 1 = 1.02925 - 1 = 0.02925

Then we multiply by 103 to get the answer in sigma-t units:
0.02925 x 103 = 29.25

Therefore, the correct answer is D) 29.25.
