was an approximate fivefold higher abundance of normalized transcripts assigned to dinoflagellates in the bloom sample relative to the non-bloom samples (Figure 2c), further confirming pigment and micro- scopic determinations of elevated dinoflagellate bio- mass and cell density at the bloom station....
To analyse the molecular content of the melanosome-like bodies, samples of grains were removed from the eye (as well as from other parts of the fossil and surrounding sediments) using a sterile scalpel, and subjected to ToF-SIMS analysis. The resulting mass spectra, which are formed by ...
