Keigwin, L.D. and R.S. Pickart. 1999.
Slope Water Current over the Laurentian Fan on Interannual
to Millennial Time Scales.
Science, Vol. 286, no. 5439, pp. 520-523, 15 October 1999.
DOI: 10.1126/science.286.5439.520
The strength and position of surface and deep currents
in the slope water south of Newfoundland are thought
to vary as a coupled system in relation to the dipole
in atmospheric sea level pressure known as the North
Atlantic oscillation (NAO). Paleoceanographic data
from the Laurentian Fan, used as a proxy for sea surface
temperature, reveal that surface slope waters north of
the Gulf Stream experienced warming during the Little
Ice Age of the 16th to 19th centuries and support the
notion of an NAO-driven coupled system. The NAO may be
a useful model for millennial-scale ocean variability
during interglacial climate states.
STUDY NOTES: High resolution planktonic foraminifera census and
geochemical data from two cores in the Laurentian Fan
region of the North Atlantic, for the last 2000 years.
The abundance of the left-coiling form of Neogloboquadrina
pachyderma (N.pachy.s.), as a percentage of the total
planktonic foraminiferal fauna in the >150um size fraction,
is utilized as a paleotemperature proxy. Data include
N.pachy.s. and total planktonic foraminifera counts,
plus carbonate content and sediment "redness" measurements.
