Autonomous eDNA collection using an uncrewed surface vessel over a 4200‐km transect of the eastern Pacific Ocean

open access: yesEnvironmental DNA, Volume 6, Issue 1, January–February 2024.
An uncrewed surface vessel and an automated eDNA sample collection device were used to obtain eDNA samples over a 4200‐km, 29‐day voyage in the eastern North Pacific Ocean. The results of the study revealed important technical considerations for acquiring samples autonomously and highlight how these platforms can increase the accessibility of obtaining
