Abstract:
We construct a 35 Myr-long d13Cbenthic megasplice, a record that consists of different high-resolution benthic isotope records 'spliced' together. In contrast to existing compilations that mix time-equivalent data across sites, the megasplice consists of data from a single site at any point in time, allowing analyses that require a high-resolution record at astronomical resolution.
