PHILADELPHIA -- While the big story of the day is the slush that's being laid down in the gaps under the boards and between the ice panels, another item made its way onto the Winter Classic rink surface.
Two thin cables were laid on opposite ends of the ice, each with a small temperature gauge at the end of it. Called Eye on the Ice, the gauges relay vital, real-time information to NHL Senior Facilities Operations Manager Dan Craig.
"(Eye on the Ice) is a monitoring system we have that will tell us the temperature on the panels themselves," Craig told NHL.com. "Once we build an inch of ice we'll put another cable in which will give us the temperature an inch off the panel, and then I'll walk around with an a hand-held infrared gun for temperature. It gives us all three parameters of what it is in the ice surface."
Eye on the Ice is important for Craig, who can monitor the rink surface 24 hours a day, either from on-site or a remote location. With that information, Craig or his crew can adjust the temperature on the panels and create the perfect situation for making ice.
