Abstract We demonstrate the use of Fourier transform
infrared spectroscopy (FTIRS) to make quantitative
measures of total organic carbon (TOC), total
inorganic carbon (TIC) and biogenic silica (BSi)
concentrations in sediment. FTIRS is a fast and costeffective
technique and only small sediment samples
are needed (0.01 g). Statistically significant models
were developed using sediment samples from northern
Sweden and were applied to sediment records from
Sweden, northeast Siberia and Macedonia. The correlation
between FTIRS-inferred values and amounts of
biogeochemical constituents assessed conventionally
varied between r = 0.84–0.99 for TOC, r = 0.85–
0.99 for TIC, and r = 0.68–0.94 for BSi. Because
FTIR spectra contain information on a large number of
both inorganic and organic components, there is great
potential for FTIRS to become an important tool in
paleolimnology.
