abstract:
'Large quantities of plastic pollution are accumulating at small island nations across the western Indian Ocean. Despite a historical focus on terrestrial inputs, recent research suggests that most pollution arriving at some islands may come from fishing and shipping activity. We use a 2D Lagrangian particle-tracking model, combined with satellite-tracked shipping and fishing data, to identify major fisheries and shipping lanes which are responsible for plastic debris beaching at the Seychelles. Virtual particles, representing plastic debris, are released monthly over multiple decades and are advected by currents from a 1/50°(2 km) regional ocean model. We find most fishing debris originates from within the Seychelles’ own exclusive economic zone, and sources of shipping debris are concentrated along major shipping routes. Sources vary seasonally, due to wind-induced reversals of surface currents between monsoons. Finally, we find variation in the quantity and seasonality of debris accumulation on a sub-island scale. Therefore, higher-resolution models that resolve local currents and kilometre scale islands may play a vital role in clean-up and management efforts.',

'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.',
