A suite of surface sediment samples from
three Icelandic lakes was analysed for subfossil
chironomid head capsules, and a quantitative July
air temperature inference model was applied to the
data to investigate whether there was significant
variability among samples taken from a lake. Ordination
and simple regression methods were used to
analyse the relationships between environmental and
sedimentological variables and the chironomid
assemblages and inferred temperature data. Substrate
was the most important influence on the chironomid
assemblages and inferred temperatures, while water
depth at the sampling location had no relationship
with the chironomid-inferred temperatures. Withinlake
variability of the chironomid assemblages and
their inferred temperatures, however, were not significant
statistically, suggesting that in lakes of
western and northwest Iceland within-lake sampling
location has no effect on the data obtained, and
therefore on training set samples.
