|a Understanding relative sea level (RSL) rise
during periods of rapid climatic change is
critical for evaluating modern sea level rise
given the vulnerability of Antarctic ice
shelves to collapse [Hodgson et al., 2006],
the retreat of the world’s glaciers [Oerlemans,
2005], and mass balance trends of
the Greenland ice sheet [Rignot and Kanagaratnam,
2006]. The first- order pattern of
global sea level rise following the Last Glacial
Maximum (LGM, ~21,000 years ago) is
well established from coral [Fairbanks,
1989], continental shelf [Hanebuth et al.,
2000], and other records [Pirazzoli, 2000]
and has been integrated into a global ICE- 5G
model of glacio- isostatic adjustment (GIA)
[Peltier, 2004]. However, uncertainty introduced
by paleo water depth of sea level indicators,
radiocarbon chronology (i.e., reservoir
corrections for marine shell dates),
postglacial isostatic adjustment, and other
processes affecting vertical position of former
shorelines produces scatter in RSL
curves, limiting our knowledge of sea level
rise during periods of rapid glacial decay.
One example of this limitation is the Gulf of
Mexico/Florida region where, despite
decades of study, RSL curves produce two
conflicting patterns: those showing progressive
submergence with a decelerating rate
during the past 5000 years [Scholl et al., 1969]
and those showing high sea level during the
middle of the Holocene [Blum et al., 2001;
Balsillie and Donoghue, 2004], where the
Holocene represents a geologic epoch that
extends from about 10,000 years ago to present
times. This discrepancy is emblematic of
the uncertainty surrounding Holocene sea
level and ice volume history in general.
Tampa Bay is a shallow (~4 meter depth)
estuary formed by dissolution of the Miocene
Arcadia Formation [Hine et al., in
press] and deposition of Quaternary sediments
in sinkholes and karst depressions
during glacio- eustatic sea level cycles. The
Tampa Bay Study (http://gulfsci.usgs.gov/
tampabay/index.html), a collaborative project—
between the U.S. Geological Survey
(USGS), and the University of South Florida
and Eckerd College, both in St. Petersburg—
is investigating the sea level, climatic, and
environmental history of Tampa Bay (Figure
1). Here we report on the sedimentary
record of early Holocene sea level rise and
its relationship to regional and global sea
level and polar ice volume |
