The lonely Algae

From the last time we collected water, I took a drop to check under a microscope, to get an insight into what is hiding. But no, no universe here. Nothing that swam, floated or hovered. No signs of spring bloom. But then, suddenly, in one corner of this drop I found something. A solitary microalgae, alone in this vast drop universe.

Tiny Arctic wildlife matters

Hello from another fine day from the largest research vessel in Norway - Kronprins Haakon. After having a delicious pizza lunch on board today, I came up to the 7th deck (yes that’s right, this boat has 10 decks), to write this blog in the conference room – a nice, cozy room with a great view. How is a girl from the south of India where winter is 20 degrees, surviving up here in the Arctic, you ask?
