Ingolf was used for two oceanographic expeditions during the summer months of 1895 and 1896, collectively known as the Ingolf Expedition.
The cruises were financed by the Danish Government and had the objective of studying the bathymetry around Iceland, northwards toward Jan Mayen and off West Greenland, heavily inspired by the Challenger expedition and similar American and German expeditions.
Commander both years was the experienced captain C.F. Wandel and scientific crew consisted of three zoologists (Hector Jungersen, William Lundbeck, and H.J. Hansen, replaced in 1896 by Carl Wesenberg-Lund), one botanist (Carl H. Ostenfeld) and one hydrographer (Martin Knudsen).
Despite severe weather and ice conditions thousands of hydrographical measurements were taken and biological samples collected at a total of 144 stations, down to depths of 3500 meter.
The results are published in the impressive report The Danish Ingolf-Expedition' (1899–1942, 5550 pages and 333 plates).
The most significant results were the demonstration of two different bottom faunas separated by the Wyville Thomson Ridge south of the Faroe Islands and the systematic difference in temperature of the water at the sea floor between the north and south side of the ridge; and the very large number of small crustaceans collected by means of H.C. Hansen's method of filtering the bottom mud with fine silk gauze rather than a metal sieve.
A very large number of species of micro-crustaceans were thus described for the first time based on the material collected by the Ingolf expedition.
