 Good afternoon. If you are a scientist working on water samples from lakes and oceans, I'm sure that you would rather spend your time working on representative samples, rather than on samples that are artificial mixtures produced by your sampling apparatus and procedures. If so, I urge you to take a look at the 2020 Limnology and Oceanography Methods paper authored by my former student Chris Parvet, Lucata Spade, that's me, Victoria Coles and Lee Cooper. This paper is entitled, Sampling Errors Arising from Carousel Entrainment and Insufficient Flushing of Oceanographic Sampling Bottles. In this paper, we show that neglecting the impacts of entrainment and bottle flushing times can produce samples that are not representative. We also show that UPCAS CTD data can be misleading due to entrainment. In addition, the paper includes data suggesting that there can be sample stratification within-water sampling bottles and provides evidence that haphazard cocking of bottles can lead to increased flushing times. Finally, suggestions are provided for alleviating these problems. I hope that you find our paper informative and useful. Happy sampling and apologies from this amateur video, a story in an age of social distancing. Good afternoon.
