Resolving abrupt frontal gradients in zooplankton community composition and marine snow fields with an autonomous Zooglider

open access: yesLimnology and Oceanography, Volume 70, Issue S1, Page S102-S120, July 2025.
Abstract An autonomous Zooglider navigated across the California Current Front into low salinity, minty waters characteristic of the California Current proper in both summers of 2019 and 2021. Diving to 400 m depth, Zooglider transited another near‐surface frontal gradient somewhat inshore. These frontal gradients were generally associated with changes

Fluorescence patterns and diversity of hydrozoans from Bocas del Toro, Panama

open access: yesCiencias Marinas
Many metazoans contain molecules capable of fluorescence, the absorption and re-emission of light. Since the anatomical distribution, or patterning, of these molecules is variable across taxa, patterns of fluorescence may serve as a powerful diagnostic ...

Investigating pelagic biodiversity and gelatinous zooplankton communities in the rapidly changing European Arctic: An eDNA metabarcoding survey

open access: yesEnvironmental DNA, Volume 6, Issue 3, May–June 2024.
In this study, we implement eDNA metabarcoding to investigate patterns of pelagic diversity in the European Arctic. We successfully detected a wide range of taxa belonging to the marine metazoan and gelatinous zooplankton communities. We demonstrate vertical patterns of diversity as well as relationships between taxa and water mass indicators such as ...

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
