Dr Jenny Pike

Dr Jenny Pike - Cardiff School of Earth and Ocean SciencesJenny investigates the seasonality in late Quaternary climate and ocean history that is preserved in diatom-rich sediments (diatom palaeoecology, diatom silica oxygen isotope analysis, sedimentology). She is also interested in the processes involved in early sediment fabric production and preservation (e.g. diatom taphonomy, microbioturbation), and the pitfalls of the subsequent interpretation.

Cathy Stickley analysing Antarctic
diatoms using the SEM. 

Current research projects focus on the palaeoceanographic reconstruction of sea ice history and glacial discharge into the Antarctic coastal ocean using late Quaternary sediments from the Antarctic margin.

 

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
