From: Contribution of ammonia oxidation to chemoautotrophy in Antarctic coastal waters
Abundance of Thaumarchaeota amoA versus rrs genes in samples from Antarctic continental shelf waters. Symbols represent water masses and dates sampled as shown in the legend. Late winter samples (filled symbols) were collected in September 2010. Summer samples (open symbols) were collected in January 2011. Upper Antarctic surface water (UAASW, filled circles); lower AASW (LAASW, filled squares); and CDW (filled triangles); WW (squares); and CDW (triangles). A line of slope=1 is shown for reference.
