abstract:
'By tracking the water mass histories of genetic samples, we investigated the biophysical dynamics shaping eukaryotic phytoplankton populations in a nutrient-deplete subtropical gyre, where cyanobacteria have a competitive advantage. Triplicate seawater samples were filtered every 46 km along a 2,382 km North Pacific transect, spiked with genomic internal standards, and amplified with a three-domain primer set to obtain absolute 16S and 18S rRNA volumetric gene abundances. The transport histories of each sample were simulated by advecting mesoscale Lagrangian particle clouds in satellite remote sensing velocity fields. Consistent with previous field studies, eukaryotic phytoplankton were anomalously abundant within eddies and along eddy-edges, where vertical circulations redistribute nutrients. Outside of eddies, we found a statistically significant decline in eukaryotes as a function of lateral coherence: Waters that recently mixed from multiple origins supported eukaryote anomalies resembling those of eddies, whereas eukaryotic populations were depressed from isolation in waters that were coherent for three or more months. In these coherent outside-eddy water masses, we estimate taxon-dependent eukaryote population half-lives range from 8 to 17 mo. Such physical conditions are relatively rare, given that 90% of the entire gyre during the sampling campaign was composed of eddies and recently mixed waters. These results derived from empirical observations substantiate the theory that eukaryotic phytoplankton would face exclusion in the subtropics on timescales of years due to competitive pressure from cyanobacteria, yet are sustained in small numbers by regular disturbances promoting opportunistic growth and dispersal.',

'Dense, cold water passes through the Faroe Bank Channel contributing to the lower branch of the Atlantic Meridional Overturning Circulation. Observations show that the bottom water warmed at an average rate of 0.1°C per decade since the early 2000s. Using GLORYS12 reanalysis (1/12°), we find that it captures the observed variability, including warming and a lagged salinification trend. To investigate the sources and pathways of warming dense bottom waters, we use GLORYS12 output and seed Lagrangian particles in the Faroe-Shetland Channel (FSC) from 2000 to 2020, backtracking them for 10 years. We find two upstream flow pathways, one via the East Greenland and one through the Jan Mayen (JM) Channel. These two source flows converge, both via cyclonic circulation around the Iceland Sea into the East Icelandic Current (EIC), and where the EIC and southward flow along the JM Ridge merge. The total western-sourced overflows subsequently follow the north slope of the Iceland-Faroe Ridge (IFR) and the Faroe plateau before entering the FSC. Particles either directly enter the FSC or overshoot the channel and recirculate southwards along the Norwegian shelf slope. An additional eastern pathway emerges from a previously overlooked source along the Norwegian shelf slope originating from the Lofoten Basin. The Greenland Sea deep gyre warms faster than other deep regions in the Nordic Seas, but particle transit through the basin center is rapid, indicating limited retention. However, recirculation and lateral exchanges can distribute warmer interior waters from the Greenland Sea into surrounding basins.',
