1 Length of tow calculated by dividing average speed of tow by time towed.

2 Estimated surface area sampled calculated by multiplying Length of Tow by 1852 (meters per nmi) and multiplying the sum by 7.317 (width of trawl in meters). 

3 Water temperature was recorded from ship-based temperature-sensing equipment and converted from Fahrenheit. Accuracy of this equipment has not been evaluated.
