title = "Operational modelling to assess advective harmful algal bloom development and its potential to impact aquaculture",
abstract = "A particle tracking model is described and used to explore the role of advection as the source of harmful algal blooms that impact the Shetland Islands, where much of Scotland's aquaculture is located. The movement of particles, representing algal cells, was modelled using surface velocities obtained from the 1.5 km resolution Atlantic Margin Model AMM15. Following validation of model performance against drifter tracks, the model results recreate previously hypothesised onshore advection of harmful algal cells from west of the archipelago during 2006 and 2013, when exceptional Dinophysis spp. abundances were measured at Shetland aquaculture sites. Higher eastward advection of Dinophysis spp. cells was also suggested during 2018. Wind roses explain this higher eastward advection during 2006, 2013 and 2018. The study suggests that the European Slope Current is important for the transport of harmful algal blooms, particularly those composed of dinoflagellates.",

note = "Funding Information: Funding for this work came from a PhD studentship from the European Social Fund and University of the Highlands and Islands (UHI_SAMS_DSW_PGR_AY16/17). KD and AD were funded by the UKRI project : Evaluating the Environmental Conditions required for the Development of Offshore Aquaculture (Off-Aqua) BB/S004246/1. PD also acknowledges funding from the European Union's Horizon 2020 research and innovation programme under the Marie Sk{\l}odowska-Curie grant agreement No 101034309 . MASTS small grant No. SG401 was used to purchase three SouthTEK Sensing Technologies Offshore Nomad drifters used in this study. We are also grateful to the crew of the RV Moder Dy who provided practical assistance in fieldwork, and the population of the Shetland Islands who helped look out for drifters. Cathy King has been especially helpful when discussing cysts around Shetland. We would like to thank the two anonymous reviewers who gave helpful feedback and suggestive edits to improve this manuscript. Publisher Copyright: {\textcopyright} 2023 The Author(s)",
