FRAM, the Fine Resolution Antarctic Model used two equations of state.
During the main run, the Eckart equation of state was used. During the
sea-ice run a scheme based on the international equation of state for
seawater (EOS80) was used. This report documents the two algorithms,
discusses their errors and compares their performance with other equation
of state algorithms.

FRAM, the UK Fine Resolution Antarctic Model, (Webb et al 1991) was based
on the Cox (1984) version of the Bryan-Cox-Semtner oceanic general
circulation model (Bryan 1969, Semtner 1974, Cox 1984).
This is usually classified as a primitive equation model because it uses
the full advection-diffusion equation for potential temperature and
salinity and a full horizontal momentum equation. During each timestep of
