A 600-year annual 10Be record from the NGRIP ice core, Greenland.
Geophys. Res. Lett., 36, L11801, doi:10.1029/2009GL038004.
Despite the extensive use of 10Be as the most significant
information source on past solar activity, there has been only
one record (Dye-3, Greenland) providing annual resolution over
several centuries. Here we report a new annual resolution 10Be
record spanning the period 1389–1994 AD, measured in an ice core
from the NGRIP site in Greenland. NGRIP and Dye-3 10Be exhibits
similar long-term variability, although occasional short term
differences between the two sites indicate that at least two
high resolution 10Be records are needed to assess local variations
and to confidently reconstruct past solar activity. A comparison
with sunspot and neutron records confirms that ice core 10Be
reflects solar Schwabe cycle variations, and continued 10Be
variability suggests cyclic solar activity throughout the
Maunder and Spörer grand solar activity minima. Recent 10Be
values are low; however, they do not indicate unusually high
recent solar activity compared to the last 600 years.
