7000 years of paleostorm activity in the NW Mediterranean Sea
in response to Holocene climate events.
Quaternary Research, Vol. 77, Issue 1, January 2012, pp. 1-11.
doi: 10.1016/j.yqres.2011.09.002
A high-resolution record of paleostorm events along the French
Mediterranean coast over the past 7000 years was established
from a lagoonal sediment core in the Gulf of Lions.
Integrating grain size, faunal analysis, clay mineralogy
and geochemistry data with a chronology derived from radiocarbon
dating, we recorded seven periods of increased storm activity
at 6300-6100, 5650-5400, 4400-4050, 3650-3200, 2800-2600, 1950-1400
and 400-50 cal yr BP (in the Little Ice Age). In contrast, our
results show that the Medieval Climate Anomaly (1150-650 cal yr BP)
was characterised by low storm activity. The evidence for high
storm activity in the NW Mediterranean Sea is in agreement with
the changes in coastal hydrodynamics observed over the Eastern
North Atlantic and seems to correspond to Holocene cooling in
the North Atlantic. Periods of low SSTs there may have led to
a stronger meridional temperature gradient and a southward
migration of the westerlies. We hypothesise that the increase
in storm activity during Holocene cold events over the North
Atlantic and Mediterranean regions was probably due to an
increase in the thermal gradient that led to an enhanced
lower tropospheric baroclinicity over a large Central
Atlantic-European domain.
STUDY NOTES: A 7000-yr high-resolution record of past storm events
using a multi-proxy analysis of sedimentary deposits
from a lagoonal environment in the Gulf of Lions
in the North-Western Mediterranean Sea.
Core PB06 is a 7.9-m-long well-dated piston core
from the Pierre Blanche lagoon in the Palavasian
wetland complex on the Gulf of Lions shore line,
water depths ~60 cm. Clay minerals were identified
by X-ray diffraction (XRD). The ratios of smectite/
(illite+chlorite) were used as indicators to reconstruct
changes in the sedimentation sources from the Mosson
drainage basin versus the marine environment, and have
been shown to be strongly linked to paleostorm events.
Low values of SM/(Il+Cl) ratio correspond to periods
of high storm activity in the NW Mediterranean Sea.
