Geological Geology Geomorphology flying spit spit Great Lakes Lake Maumee Lake Erie grain size analysis Friedman principal component analysis modal analysis Presque Isle ground penetrating radar polymodal STATS program Glacial Lake Maumee (an early ancestor to Lake Erie) developed extensive beach ridges and bars that included an elongate arcuate bar complex at Columbus Grove, OH, that was very similar to the modern Presque Isle flying spit at Erie, PA, in terms of shape, its 10 km length, its shoreline orientation, and its angle from the coast, although it is extremely narrow, distally discontinuous, and extremely thin. The bars consist of relatively fine-grained, poorly sorted, polymodal sediment that has been extensively bioturbated and plowed, although their shapes are well preserved on the modern surface and they retain useful grain size signals regarding depositional processes and settings. Lake floor sediments are primarily very fine to medium silts with secondary clays and minor sands. Bars appear to have accreted in place, locally with lateral expansion but without significant migration or erosion. Vertical successions vary from cryptic upward shoaling and coarsening to quite heterogenous (better seen by extracting peaks rather than using basic descriptive statistics). Bars are thin (commonly <.5 - 1 m), and at least some begin with a marked shift from lake-floor silt to relatively well-developed sands, although rarely as coarse as sand peaks higher in the core. This suggests initiation by extreme waves touching bottom in relatively deep places, and thereby beginning construction of a sand pile that can benefit from progressively weaker waves as it grows upward. The arcuate shape of the bar complex is attributed to waves shoaling against an accretionary bulge in the coastline. However, until the bars start to connect and become continuous, longshore drift is not developed and lateral transport is prohibited, so bar segments grow individually from locally scavenged sand. This lake phase is thought to have been too short-lived to have permitted the bar to mature into a spit and become wide and complicated. 2021-08-24 English text Kent State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=kent1626887825114558 http://rave.ohiolink.edu/etdc/view?acc_num=kent1626887825114558 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
