JOHN McMANUS; Quartile deviation-median diameter analysis of surface and core sediments from Start Bay. Journal of the Geological Society ; 131 (1): 51–56. doi: https://doi.org/10.1144/gsjgs.131.1.0051
Quartile deviation-median diameter analysis is sufficiently sensitive to permit sectors of bed characterized by wave or current dominant sediments to be recognized. These may be related to modern conditions or to erosion of buried sub-recent deposits which cores indicate exist beneath the present seabed. Although only approximately 45% of the samples are unequivocally related to either set of dynamic conditions the divisions achieved suggest that the analysis technique has a value in the shallow marine environment.
