Tracing Carbon Dynamics in the Southern Ocean and Great Barrier Reef Using Strontium and Calcium
… carbon budget. Chapter 4 explores the role of Acantharia, marine protists with star-shaped SrSO4 skeletons, in Sr cycling and POC export in the Southern Ocean. Despite initial assumptions that Acantharia would quickly dissolve in undersaturated seawater, emerging evidence shows they descend to …

The chemistry, biology, and vertical flux of oceanic particulate matter
… 210Po, and 210Pb. Biological distributions of Acantharia, dinoflagellates, coccolithophorids, Foraminifera, diatoms, silicoflagellates, Radiolaria, and tintinnids were made by light microscopy (LM) and augmented by scanning electron microscopy (SEM). Size and morphological distributions of the …

A molecular approach to questions in the phylogeny of planktonic sarcodines
… corroborate this result. The variability within acantharian SSU rDNA was significantly less than that observed in spumellaria, and may prove less useful in establishing relationships at taxonomic categories below the order level.
