Stable isotopes in a stalagmite from NW Sweden document environmental
changes over the past 4000 years.
Boreas, Vol. 39, pp. 77-86, January 2010.

This study of a 4000-year-old stalagmite from Korallgrottan
in northwestern Sweden highlights the potentials and challenges
when using stable isotopes in stalagmites as climate proxies,
as well as the fact that the relationship between climate and
proxy may change through time. Both the oxygen and the carbon
isotopes display an overall trend of enrichment together with
decreasing growth rates over the time period covered by the
stalagmite, which is considered a generally cooling period
according to current palaeoclimate understanding. The stable
isotope records show enriched isotopic values during the,
for Scandinavia, comparatively cold period AD 1300-1700
and depleted values during the warmer period AD 800-1000.
The indication of a negative relationship between measured
d18O and surface temperature concurs with earlier reported
stalagmite records from regions with a seasonal snow cover
and is further supported by the fact that the stalagmite
d18O record shows general similarities with both regional
and hemispheric temperature reconstructions available for
the past 500 and 2000 years, respectively. Compared with
a stable isotope record of lacustrine carbonates from
northern Sweden, however, shifting correlations over time
between the two records indicate that a local hydrological
change may have taken place at Korallgrottan, or at the lake,
compared with around 1000 years ago. The earlier part of the
stalagmite d18O might thus be influenced, to some extent,
by another process than the later part, which means that
a negative relationship between d18O and surface temperature
might not hold for the entire 4000-year-old record.
STUDY NOTES: Stable oxygen and carbon isotope data from Korallgrottan, northwestern Sweden. Korallgrottan is located in the Caledonian mountain range about 100 km off the North Atlantic coast in the county of Jämtland. Stalagmite K11 is 47mm long, with a basal diameter of about 50 mm.
