Noting that “the brief observational record is inadequate for characterizing natural variability in hurricane activity occurring on longer than multi-decadal timescales,” Lane et al. (2011) sought a means of characterizing hurricane activity prior to the period of modern measurement and historical record keeping, due to the fact that “the manner in which tropical cyclone activity and climate interact has critical implications for society and is not well understood.”

Specifically, Lane et al. developed a 4500-year record of intense hurricane-induced storm surges based on data obtained from “a nearly circular, 200-m-diameter cover-collapse sinkhole (Mullet Pond: 29°55.520′N, 84°20.275′W) that is located on Bald Point near Apalachee Bay, Florida, USA, where (1) “recent deposition of sand layers in the upper sediments of the pond was found to be contemporaneous with significant, historic storm surges at the site modeled using SLOSH and the Best Track, post-1851 AD dataset,” where (2) “paleohurricane deposits were identified by sand content and dated using radiocarbon-based age models,” and where (3) “marine-indicative foraminifera, some originating at least 5 km offshore, were present in several modern and ancient storm deposits.” (more…)
