Part 2 of the stable isotope project will be analyzing sea catfish #otoliths using carbon and oxygen stable isotope analyses
Otoliths are calcium carbonate structures or “stones” in the inner ear of most fish 🐠
The sea catfish otoliths are very round, but you can also get different shapes like this #dageraad
The goal is to determine the season of catch and to reconstruct body size

Working on submitting destructive sampling permits for #StableIsotope analysis of #CapeFurSeal tooth enamel, fish #otoliths and bone collagen.
Here is the seal plan: 🦭
Comparing carbon and oxygen SI of #MiddleStoneAge seals from #KlasiesRiverMainSite and #BlombosCave with #LateStoneAge seals from #Hoffman’s/Robberg and #NelsonBayCave
Planning to compare the archaeological samples with present day seal populations to see if the #foraging environments have changed.

At the moment this site feels a little like the awkward first days of a #conference where you don't really know anyone and are wondering what the etiquette is.. At some point the posters will go up and the refreshments will come out...

@CliveTrue Yup! I worked with #otoliths to study age-structure impacts of MPAs on groundfish for my MS and working on a #paleo otolith project currently, looking at holocene #otoliths of gadoids
Hi all, #Introduction time! Im an aquatic ecologist working in water science in rainy #Canberra Australia. My #phd was on freshwater fish early life history, with lots of time fiddling with #otoliths of a really cool fish, Mogurnda adspersa. My interests include #rstats #datavis and data science in general. Pic is of a small native fish in the Canberra region, Galaxias olidus. For more: www.danswell.org #sciencemastodon
