VAN POOL TOT POOL: ARKTIESE EN ANTARKTIESE SEE-YS deur Martelize Brink
About this episode
See-ys is vir die oseaan se ekostelsel soos grond vir die woud. Wanneer seewater koud genoeg word om te vries, verdryf dit sout, wat veroorsaak dat kanale in die ys vorm. Alge groei binne hierdie kanale, en vorm ‘n integrale basis van die voedselketting. Satellietdata-opnames van see-ys het in 1978 begin. Dit wys groot veranderinge oor die afgelope paar dekades. Watter rol speel see-ys in seestrome, ekostelsels en klimaat?
