Answer: A different group of scientists using different methods.
Heat energy released : 167.2 kJ
<h3>Further explanation</h3>
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
m = 2000 g
c = 4.18 J/ g ° C
∆t = 20 ° C

Its probably becuase of the amount of minerals found in the ocean floor.Salt just so happens to be a major one.not only that,but the amount of salt that the human body emits while while outside,normally by bodies of water,it could also be that.
