Human Factors
I was working Local Control 2 which controls Runway XXL and Ground Control coordinated via the land line behind short final cross Runway XXL at intersection Delta and it was approved. I was watching Diamond Star on short final at the same time [another aircraft] crossed the hold bars Diamond Star advised that he was going around. The go around was conducted before the aircraft reached the landing threshold.
I was working the Assistant Local Position monitoring LC1. Ground Control had coordinated a runway crossing at Taxiway Delta with Local 2 and Local 1. I had just received an IFR release from TRACON and was off monitor for a few seconds and then returned to listening to Local 1. Local 2 shouted out something about going around traffic was crossing. When I looked at the situation Diamond Star was starting a Climbing GO Around on Runway XXL and [another aircraft] was stopped about half way between the runway edge and the Hold Short lines. Recommendation; I do not believe we need to make any changes in procedure. The inexperienced Ground Controller should have said what he originally intended too.
Tower Controller described a go around event when coordination between a Local Controller and Ground Controller was confused and Ground Controller cleared an aircraft to cross a runway with traffic on short final.
