Much attention is devoted to Fridtjof Nansen’s talents as an academic and researcher. Nansen contributed knowledge to oceanographic disciplines which, even to this day, are still inspired by his work and vision.
Nansen crossed Greenland on skis in 1888, crossed the Polar Sea with Farm between 1893 and 1896, and set out to the North Pole on skis, though he never reached it. Nevertheless, his travels and his taste for adventure are what Nansen is best known for. But Nansen was also a gifted researcher, almost a multi-faceted genius, and possessed both breadth and depth of repertoire.
The young scientist
Nansen wrote his doctoral thesis in neurobiology during a stay at the Bergen museum. His conclusions were treated with scepticism, but in retrospect they show that Nansen’s research was ahead of its time. In fact, Nansen’s biographer Roland Huntford maintains that Nansen’s research in this field was worthy of a Nobel Prize in medicine.
The disputation for his doctoral degree took place at Norway’s only university at the time, the Royal Frederik’s University in Kristiania, now the University of Oslo, on 28 April 1888. In modern times it has become evident that Nansen’s doctoral thesis was ground-breaking. In an editorial in the reputable journal Brain, Nansen’s doctoral thesis is presented as a paradigm shift in neuroscience which “altered the course of neuroscience” (Alastair Compston 2010 Brain 133:2173-2175).

Fridtjof Nansen never followed up his studies of the nervous system, though he later came to be a source of inspiration for Norwegian neuroscience researchers. What he did follow up from his doctoral thesis, however, was his study of food species. He studied the nervous systems of the slime eel as well as that of the lobster, crayfish and shell.
Nansen devoted much of his time to understanding the ocean and ocean life, and was a professor of zoology between 1897 and 1908 and of oceanography between 1908 and 1930 at the Royal Frederik’s University.
In other words, for Nansen the future of science revolved mainly around the Polar Sea. When Nansen set out on his expedition with Fram in 1893, it was as much about investigating the ocean currents as it was about conquering the North Pole, and he saw no contradiction in motivation between them.
Crushed myths and new insight
In collaboration with Bj?rn Helland-Hansen, Nansen proved that the seabed could reach sub-zero temperatures. He used this knowledge of sea temperatures to say something about the marine biology, including the variation in fish stocks. Knowledge of variations in fish stocks has been important in work on managing fish resources. Nansen’s contribution in this field has had significance for the fish management regime that exists today in the High North.
Nansen’s measurements of ocean depths provided new insight into the ocean areas in the High North. The general perception was that the Polar Sea was shallow, but Nansen pointed to ocean depths of many thousands of metres. He also measured areas of underwater elevations on the seabed. And, not least, Nansen was interested in the climatic significance of the sea. Through systematic observations, Nansen also studied heat
