Floating eggs | 9 June 2016 |
 | Danny Hitchcock is a Ph.D. student from the University of Oslo. He will collect 60 barnacle goose eggs to study stable isotopes and pollution levels. He hopes to correlate migration pattern and timing of laying with pollution loads. Today he collected the first 12 eggs. He is estimating the incubation period by floatation technique. Later he can callibrate this. |
| Floatation technique: while the incubation progresses, the air chamber in the egg becomes bigger and the egg will float more upright in a water bowl. | |
| Kathrin Lang was today his guard and field assistant and she made this picture. |
