Abstract

In this study we present a comparative quantification of CaCO3 production rates by rhodolith-forming coralline red algal communities situated in high polar latitudes and assess which environmental parameters control these production rates. The present rhodoliths act as ecosystem engineers, and their carbonate skeletons provide an important ecological niche to a variety of benthic organisms.
The settings are distributed along the coasts of the Svalbard archipelago, being Floskjeret (78◦180N) in Isfjorden, Krossfjorden (79◦080N) at the eastern coast of Haakon VII Land, Mosselbukta (79◦530N) at the eastern coast of Mosselhalvøya, and Nordkappbukta (80◦310N) at the northern coast
of Nordaustlandet. All sites feature Arctic climate and strong seasonality.
