Investigating nutrient dynamics and eukaryotic phytoplankton distribution in nutrient-deplete subtropical gyres, suggesting environmental implications.

Key Points

This research aims to understand the biophysical dynamics affecting eukaryotic phytoplankton populations in a subtropical gyre with nutrient limitations.
Tracked water mass histories of genetic samples from a 2,382 km North Pacific transect.
Filtered triplicate seawater samples and amplified 16S and 18S rRNA for molecular analysis.
Simulated transport histories using mesoscale Lagrangian particle clouds and satellite remote sensing data.
Eukaryotic phytoplankton showed increased abundance within eddies, while outside-eddy areas exhibited significant declines.
Eukaryote population half-lives ranged from 8 to 17 months depending on taxa, with coherent water masses leading to lower populations.
Most waters (>90%) during the sampling were influenced by eddies or had recently mixed origins.
