AbstractEnvironmental DNA (eDNA) is increasingly utilized for detecting single species and monitoring biodiversity in the ocean. The highly dynamic marine environment affects the distribution of eDNA relative to its source organisms, complicating the interpretation of eDNA observations and challenging the design of effective field sampling campaigns. Here, an eDNA fate-and-transport model, built on an ocean model and Lagrangian particle tracking, provided a best estimate of rapidly diluted eDNA signals before the sampling campaign. Over 70% of the pre-selected stations detected the fast diluted eDNA. The model-predicted particles explained approximately 40% of the variation in eDNA abundance, despite the potentially large source variations and patchy spatial distributions. Our model revealed the essential role of ocean transport in determining eDNA abundance and dispersion, and hindcasted the source concentration by integrating eDNA observations, eDNA degradation, transport, and dilution.
