18.Winds around a persistent high pressure system drive ocean currents, creating a vortex, known as a gyre, causing debris to collect in a central location.
19.But in recent years, there's been more ice melting and that critical beaufort gyre that used to be a nursery for ice has instead become a graveyard.
