Dear Colleagues, I would be grateful to hear from anyone who has information regarding the persistence of sperm whale faeces on the ocean surface. Specifically, I am looking for information regarding how quickly sperm whale faeces sink from the surface. I aim to use this information to calculate the turbulent dispersal of faecal material in the mixed layer. This information will be used for my PhD research examining nutrient transport by sperm whales. Any information would be much appreciated and fully acknowledged. Kindest thanks, Trish Lavery BBSc, BSci(MarBiol)(Hons), PhD Candidate School of Biological Sciences Flinders University GPO Box 2100 Adelaide, SA, 5001 Tel: +61 8 8201 5234 Fax: +61 8 8201 3015 https://www.scieng.flinders.edu.au/biology/people/academic/mitchell_j/msl/ms website_ppl_lavery.htm
