Notes

Taking pictures is one of the important activities of visitors of the Arctic and this presents challenges for both humans and equipment. However, in most situations and with just a few tricks and inexpensive extra gear it is possible to use standard cameras and take home the memories of a lifetime. To avoid battery problems, it's advisable to keep a spare battery warm by storing it close to your body, then swap if your camera's battery goes low. Some wildlife requires focal lengths of 600mm or more and in general a zoom lens will come in handy. Some of Chris Marquardt's Arctic Photography

Notes

Most of the year polar areas are covered with a coat of snow which makes it challenging for humans to explore. Some of us are expert skiers, but the equipment is often bulky. Snowshoes are a very practical alternative even for those who are not initiated to this kind of gear as generally people quickly learn the basic techniques. Snowshoes are not a modern invention and the contemporary models build on a long tradition originating from different part of the Arctic.

Notes

A frequent question from the interested laymen is: “how many whales are there?”. The answer is not trivial and it is of utmost importance, not only for purely academic reasons, but also for the management and conservation of the different species. For example, it is essential to know the abundance of a species at different point in time to be able to determine if there is a decline or an increase that would indicate a potential large variation in ecosystem characteristics. From the mark-recapture technique to line-transect sampling we try to summarize and describe the most important techniques for determine the numbers of cetaceans.
