The data gathered in the program applies to ecology, weather, oceanography, soil science, biology and satellite calibration/validation research.

It simply made the announcement as soon as its own calibrations had been finalised.

"In physics, standards are used as fixed reference points for the precise measurement of physical quantities and the calibration of measuring instruments," says Gould.

"Discovery of these minute fossils tells us this group of insects has been in Aotearoa New Zealand for at least 15 million years. This provides a well-dated calibration point for molecular phylogenetic studies."
