Thanks for also listing the depth in metric. This imperial measurement system really ties me in multiples of ~.514 m/sec.
Fixed that for you.
*its (I know, I know!)
See? Right there. That's clunky. It's technically the direct object, but it's placement at the beginning of the sentence automatically makes me want to say "who do you intend to contact" right off the bat. English has come a long way from German; we don't need noun declension for "who," especially since we decline so few other words.
I think it's time we retired the word "whom" for lack of use. "Who" in this sense is more intuitive. Besides, we need fewer "special case" words.
As of next Tuesday, C will be flushed in favor of COBOL. Please update your programs.
