Nearby frost flowers. Frost flowers grow on the surface of newly formed sea ice and are very highly saline (i.e. salty). Previous measurements have shown that as these frost flowers form they can scavenge things from the atmosphere, like mercury. So scientists would like to know if they can scavenge organic pollutants, like the pesticides and industrial chemicals which are being measured here.
