Four researchers from Ice and Climate among the most cited in geoscience

ScienceWatch from Thomson Reuters is the most comprehensive list of scientific articles in the world and their annual report provides a statistical analysis of where and when the articles have been cited. On the list of the most cited researchers in the world are four researchers from the Centre for Ice and Climate at the Niels Bohr Institute at the University of Copenhagen: Professor Dorthe Dahl-Jensen, Associate Professor Jørgen Peder Steffensen, Associate Professor Matthias Bigler and Professor Emeritus Sigfus J. Johnsen.

Professor Dorthe Dahl-Jensen and Associate Professor Jørgen Peder Steffensen are on the list of the most cited researchers in the world.

The number of citations by scientific articles has a very high impact factor.
“The fact that one’s article is cited in other scientific articles means that the research has a broad interest and a very great scientific influence. One’s research thus helps to shape science,” explains Jørgen Peder Steffensen.

It is especially articles about the ice core drillings at GRIP and NorthGRIP on the Greenland ice sheet and the EPICA drilling in Antarctica that are much cited. The four researchers each have around 90 articles that have been cited in other scientific articles throughout the years. Each of the four researchers, Dorthe Dahl-Jensen, Jørgen Peder Steffensen, Matthias Bigler and Sigfus Johnsen (now deceased) has around 11,000 citations.

The number of citations is also important for university ranking worldwide (Shanghai University Ranking). There are now 9 researchers from the University of Copenhagen on the list of most cited researchers, four of which come from the Ice and Climate group at the Niels Bohr Institute.
