Abstract

High-resolution seismic and ground-penetrating-radar (GPR) data have been acquired over Lake Nikolay in the western Lena Delta in order to study the uppermost basin fill and the bordering frozen margins. GPR measurements were completed on the frozen lake and its permafrost margins, while high-resolution seismic data were acquired from the lake during open-water conditions in summer using a Chirp profiler. The combined use of the 2 profiling systems allows stratigraphic profiling in both frozen and unfrozen parts of the lake. Short sediment cores were used to aid geophysical data interpretation
