LandScales

Background

LandScales (Connecting processes and structures driving the landscape carbon dynamics over scales) integrated the aquatic and terrestrial perspectives of landscape carbon dynamics within a multidisciplinary collaborative research environment, by characterising structures, processes, and fluxes across scales. To meet this research two kettle holes were selected from the Uckermark region in Brandenburg, Northeastern Germany  (Rittgarten: N 53°23'22” E 013°42'09”; and Kraatz: N 53°25'05” E13°39'48”) and were instrumented for long-term research. Both kettle holes are surrounded by an intensely managed agricultural landscape.

Structure of LandScales. The project was set up in a matrix structure and was subdivided in three core (WP1-3) and one overarching research topics (WP4). They comprised mechanisms (WP1), fluxes (WP2) and structures/erosion (WP3) of the landscape C dynamics and had both a terrestrial and aquatic focus. Each WP was part of the Research Platform (green circle) and the Methods & Infrastructural Platform (blue triangle). The three core WP were interlinked by the assessment of uncertainty in transferring process and fluxes across scales (inner red triangle; WP 4)

Goal

Due to its multidisciplinary LandScales had several goals to meet: Some studies aimed to assess the relative importance of differences in carbon (C) quantity and quality for microbial and biogeochemical processes or quantified the GPP in temperate nutrient-rich kettle holes with different typical vegetation types, for instance. Other tested if hydroperiod and land management were imprinted on the isotopic values (δ13C, δ15N) or used isoscapes to understand the complex land-use and management patterns of the agricultural landscapes.
