Cruising an archive: On the palaeoclimatic value of the Lena Delta

摘要

Today, there are only a handful of millennial-long and annually resolved tree-ring chronologies in existence. Explicit gaps in the global distribution of these regional chronologies together with an overall declining sample size back in time compel a community-wide challenge to discover new tree ring-based climate proxy records. Here, we present evidence for a yet unexplored palaeoenvironmental archive, define allied research tasks and emphasize probable hurdles within and beyond academia, in pursuit of answering this challenge.
