Abstract:

This data set consists of environmental and geochemical information obtained from samples of 27 sediment cores collected from the vegetated shoreline of three lakes in Finland (Kallavesi, Vesijärvi and Oulujärvi). The sampling campaign occurred in August 2023. For each sediment core, we calculated the sedimentary organic carbon stock (kg/m2). We also measured environmental parameters (water depth, slope, vegetation density and fetch length) that could drive the accumulation of organic carbon in the sediments.

8	Fetch length, mean	Fetch l	m	Jilbert, Tom	Calculated	For each sampling site (A - I), the distance to the nearest shoreline (either lake shoreline or islands) was calculated considering 48 angles (from 0 to 345°, by 15° increments). The average of these 48 distances is considered as the "average fetch length".
9	Soil organic carbon, stock	SOC stock	kg/m²	Jilbert, Tom	Calculated	Considering the organic-rich surface layer (individual samples with OM >0.5%) of the uppermost 1m. Source: doi:10.1594/PANGAEA.986726
