Marine snow in Antarctic coastal waters
Abstract: Fragile macroscopic aggregates consisting of a matrix of non-living organic material and inhabited by prokaryotic and eukaryotic microorganisms have been reported from many areas of the world's oceans. These aggregates, referred to as marine snow, are sites of enhanced biological acti...

Marine snow collected in mid January 1994 consisted principally of diatoms and mucilage derived from the sea-ice community while the collections made at the end of that month contained much colonial Phaeocystis.
