Kulhanek, Denise Kay (2009): Calcareous nannoplankton as paleoceanographic and biostratigraphic proxies; examples from the Mid-Cretaceous Equatorial Atlantic (ODP Leg 207) and Pleistocene of the Antarctic Peninsula (NBP0602A) and North Atlantic (IODP Exp. 306). 193 pp., georefid:2010-081080
Abstract:
This dissertation is a collection of three projects utilizing calcareous nannoplankton as biostratigraphic and paleo-oceanographic indicators. The materials studied come from three locations: (1) Ocean Drilling Program (ODP) Leg 207 (Site 1258) on Demerara Rise; (2) SHALDRIL II Cruise NBP0602A (Site 9) in the James Ross Basin, western Weddell Sea; and (3) Integrated Ocean Drilling Program (IODP) Expedition 306 (Site U1313) in the North Atlantic. Chapter 2 details the results from Site 1258, drilled during ODP Leg 207 on Demerara Rise off the northern coast of South America. Chapter 3 details the results of a study of calcareous nannofossils in clasts obtained during the SHALDRIL II NBP0602A cruise to the Antarctic Peninsula. Chapter 4 presents results from a Pleistocene study of calcareous nannoplankton assemblages spanning 480-355 ka at IODP Site U1313. This site was a reoccupation of Deep Sea Drilling Project Site 607, drilled on the western flank of the Mid-Atlantic Ridge. (mod. auth. abst.)
