Quantitatively analyze the seafloor distribution of taxa to identify assemblages, which in turn can be related to SST and other environmental variables.

Bryozoan MART Analysis
Good relationship between zooid size in cheilostome bryozoa and mean annual range in temperature (MART). This provides a proxy for seasonality, and when coupled with oxygen isotope analyses of frontal walls, absolute temperature.
