The more reliable data is available on past climate periods, the more accurate climate change models can be. Scientists at Jacobs University Bremen and the Alfred Wegener Institute (AWI) aim to use new machine learning methods to uncover climate information hidden in sediment cores.
Sediment cores are climate archives. Much like tree growth rings, they tell of changing environmental conditions, such as temperature fluctuations, precipitation, or water acidification. "However, they often reveal information about climate only indirectly. In addition, the data often does not add up because it was collected using different methods," described Peter Zaspel when explaining the problem. The professor of computer science is responsible for the research project at Jacobs University. He cooperates with physicist Professor Thomas Laepple from the AWI. Also involved in the project are the biogeochemistry professor, Jelle Bijma from AWI and Jacobs University, and Professor Vikram Unnithan, geoscientist at Jacobs University.
In order to be able to reconstruct past climate conditions, a machine learning method developed by Professor Zaspel is being used in the project. It is a multi-fidelity method that has already been successfully tested in another field. "It generates the best possible information from data that is only comparable to a limited extent," said Professor Zaspel. This new reconstruction technique aims to provide better insights into past climate trends.

About Helmholtz School for Marine Data Science:
The “Helmholtz School for Marine Data Science” (MarDATA) is a graduate school, financed by the Helmholtz Association. It aims to define and educate a new type of “marine data scientists” by introducing and embedding researchers from computer sciences and mathematics into ocean sciences, covering a broad range from supercomputing and modelling, (bio)informatics, robotics, to statistics and big data methodologies. Researchers from the German leading institutes for marine research, the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Alfred-Wegener-Institute (AWI) Helmholtz Centre for Polar and Marine Research, will jointly educate and supervise doctoral (PhD) candidates together with information & data science specialists from their partner universities in Kiel (Kiel University) and Bremen (University of Bremen and Jacobs University). The broad education in joint block courses, international summer schools and colloquia goes beyond a single discipline towards genuine scientific insight into and a more systematic treatment of marine data.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
