Bo Vinther (Niels Bohr Institute) will be joining us as co-author of the Science paper. Bo
provided a correction factor for the isotope values from DYE-3 to account for changes in in
the elevation of the ice that flows to the drill site, which we used in the synthesis. He
also provided the annual data keyed to his most recently revised age models for Agassiz,
Renland, and for NGRIP. Our paper will be the first to publish NGRIP data at a resolution
higher than 20-year averages. Including Bo will provide representation from the N
Hemisphere ice-core community, and satisfies NGRIP protocol for data publication.
SCIENCE policy requires "Any changes in authorship must be approved in writing by all
the original authors". I will now inform Science of the modification and expect that you
will hear from the editorial staff.
Let me know if you have any questions or concerns.
