When Polarstern cruises through sea-ice, we complement our shipbased counts of marine birds and mammals with surveys from the helicopter. The reason is that when in ice, the ship often searches an erratic track through leads in the ice, whereas for good surveys it is crucial to sample the water en ice-landscape in an unbiased straight transect line. So, weather permitting, we make a flight once a day, taking us about a hundred kilometres to the north or south and back. Such a flight takes about two hours and to be honest, that is more than enough. Ears are pounding from the loud noises and ones eyes nearly drop out from searching penguins and seals in an ice landschape flashing along with a speed of 100 km per hour. Back on the ship we waggle out of the heli like a confused penguin in urgent need for a mug of coffee to recover.
