Coralline alga reveals first marine record of subarctic
North Pacific climate change.
Geophys. Res. Lett., 34, L07702, doi:10.1029/2006GL028811.
While recent changes in subarctic North Pacific climate had dramatic
effects on ecosystems and fishery yields, past climate dynamics and
teleconnection patterns are poorly understood due to the absence of
century-long high-resolution marine records. We present the first
117-year long annually resolved marine climate history from the
western Bering Sea/Aleutian Island region using information contained
in the calcitic skeleton of the long-lived crustose coralline red alga
Clathromorphum nereostratum, a previously unused climate archive.
The skeletal d18O-time series indicates significant warming and/or
freshening of surface waters after the middle of the 20th century.
Furthermore, the time series is spatiotemporally correlated with
Pacific Decadal Oscillation (PDO) and tropical El Niño-Southern
Oscillation (ENSO) indices. Even though the western Bering Sea/
Aleutian Island region is believed to be outside the area of
significant marine response to ENSO, we propose that an ENSO signal
is transmitted via the Alaskan Stream from the Eastern North Pacific,
a region of known ENSO teleconnections.
STUDY NOTES: 117 year oxygen isotope record of the coralline alga
Clathromorphum nereostratum, collected off Attu Island
in the western Aleutian Islands. C. nereostratum is a
long-lived, shallow-marine crustose coralline algae.
Attu Island: 52°47'N, 173°10'E
