Arctic Environmental Data Analytics

The goal of this PhD  is to detect the past ecosystem‐climate relationships in Arctic lake settings by big data analytics of a polar proxy dataset. We focus on two topics: Data management and data science ‐ development of a data analytics system for palaeolimnological proxy data designed for multivariate statistics. Geoscience ‐ Past and present environmental dynamics in Arctic landscapes and their impact on polar lake ecosystems. A unique, standardized, data set of proxy data from lake sediment cores in the Eastern Arctic will be compiled using the new PALIM Database. To correlate ecosystem changes with climate changes, multivariate statistics will be performed on quality controlled biotic and abiotic proxy data. The objective of this project is to develop a state‐of‐the‐art data analytics system that allows to detect the main relationships of ecosystem dynamics and climate changes and their spatiotemporal pattern in dependence to lake attributes, i.e. thermokarst or glacial origin, landscape‐type, lake‐ecosystem‐type, lake age, and catchment‐vegetation.
