Living diatoms generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion tonnes of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor.
I recently joined mastodon like many, many others. My first impression is that I like it here! I shall shortly introduce myself. I've moved to Iceland from the Netherlands for a PhD in #Fisheries in 2016, and have stuck around on the stormy island since.
