Note The icing of external recorders during the polar winter
Abstract: Recorders and transmitters are commonly attached to suitable polar species of vertebrates. When using these devices, power and memory are two of the most limiting fac-tors in successful experiments. To conserve power and memory the units are often pro-grammed to record or transmit at desig...

To conserve power and memory the units are often pro-grammed to record or transmit at designated times. A commonly used sensor is operational only when the animal is in sea water.

Using satellite transmitters that were programmed to transmit only after they were dry for a prescribed time, we noted an uncom-mon number of failures in transmission. On later controlled experiments using captive emperor penguins, Aptenodytes forsterii, we found that mock transmitters formed a glaze of ice over their surface while the birds were diving freely into an ice hole cut in two meter thick sea ice. We concluded that the icing caused the sensor to fail in detecting when the birds had re-entered the water.
