Even though sinkhole occurrences continue to receive media attention, more research is needed in the Geosciences. This paper examines the suitability of this work as a Geomorphology application from a Physical Geography standpoint. More specifically, it aims to examine an existing online dataset in search of any spatial-temporal trends in sinkhole formation in Florida counties where there are limestone deposits. Although dates have been reported for known reported sinkholes, considerations have not particularly focused on the temporal span of occurrences. By examining the seasonality of sinkhole occurrence, for example, it is possible to discern any effects of heating or cooling associated with processes that are connected to temperature and seasonal climate. This study is relevant to an understanding of climate change impacts on the formation and appearance of these erosional landforms.
