Jenny investigates the seasonality in late Quaternary climate and ocean history that is preserved in laminated, diatom-rich sediments. She is also interested in the processes involved in early sediment fabric production and preservation (e.g. diatom taphonomy, bioturbation and microbioturbation fabrics), and the pitfalls of the subsequent interpretation.
Cathy Stickley analysing Antarctic
diatoms using the SEM.
Current research projects focus on the palaeoceanographic analysis of diatom assemblages and laminated sediments from coastal Antarctica, in particular, the East Antarctic margin and the Antarctic Peninsula regions.
Techniques employed in this research include: Scanning electron microscope (SEM) backscattered electron imagery of sediment composition and fabrics; SEM secondary electron imagery of diatom assemblages; Palaeoecological analysis of sequences of diatom assemblages; and Diatom silica oxygen isotope records
