Measurements of valves of the diatom Fragilariopsis kerguelensis from a sediment trap in the Southern Ocean

Morphometric measurements of Fragilariopsis kerguelensis valves from a two-year time series covering the period from November 2002 to October 2004 collected by a sediment trap at 800m below the ocean surface which was moored near 54° S 140° E in ca. 2300 m water depth, close to the top of the Australia-Antarctica mid-ocean ridge.
