Strom, A.S., R.C. Francis, N.J. Mantua, E.L. Miles, and D.L. Peterson. 2004. North Pacific climate recorded in growth rings of geoduck clams: A new tool for paleoenvironmental reconstruction. Geophysical Research Letters 31:L06206.
The Pacific Decadal Oscillation (PDO), the leading mode of
sea surface temperature (SST) anomalies in the extratropical
North Pacific Ocean, has widespread impacts on precipitation
in the Americas and marine fisheries in the North Pacific.
However, marine proxy records with a temporal resolution that
resolves interannual to interdecadal SST variability in the
extratropical North Pacific are extremely rare. Here we
demonstrate that the winter Sr/Ca and U/Ca records of an
annually-banded reef coral from the Ogasawara Islands in the
western subtropical North Pacific are significantly correlated
with the instrumental winter PDO index over the last century.
The reconstruction of the PDO is further improved by combining
the coral data with an existing eastern mid-latitude North
Pacific growth ring record of geoduck clams. The spatial
correlations of this combined index with global climate fields
suggest that SST proxy records from these locations provide
potential for PDO reconstructions further back in time.
STUDY NOTES: We generated an index of reconstructed Pacific Decadal
Oscillation (PDO) variability by combining the
November-December-January-February (NDJF) Sr/Ca and U/Ca
time series of the Ogasawara coral record (Felis et al., 2009)
with a growth index based on geoduck clams (Panopea abrupta)
from the Strait of Juan de Fuca (Strom et al., 2004),
a coastal site in the eastern midlatitude North Pacific
(~48.12°N, 122.95°W, Washington State, northwest U.S.).
The NDJF coral Sr/Ca and U/Ca time series were calculated
from the bimonthly resolved coral record as the average of the
corresponding November-December (ND) and January-February (JF)
values. The NDJF value of a given year (e.g., 1901) includes
the ND value of the preceding year (1900). The ring-width
index is based on annual growth rings of 6 to 23 geoduck shells,
and has been reported to document local SST and PDO variability
(Strom et al., 2004). All three time series were detrended
and normalized to unit variance over their period of overlap
(1873-1994). Then, a coral index was calculated as the average
of the detrended and normalized NDJF Sr/Ca and U/Ca time series.
Consequently, the coral-geoduck index was derived as the average
of this coral index and the detrended and normalized geoduck
growth index (Felis et al., 2010).
Core OGA-02-1 was drilled vertically through a living Porites
coral at Miyanohama on the north coast of Chichijima in the
Ogasawara Islands (Japan). The core is without gap over its
total length of 1.74 m.
