Pollen for dating

Pollen sample for accelerator mass spectrometry dating, seen through a microscope.

Some of the sediment in the Ōkārito core does not contain much organic material, so pollen is concentrated to give a big enough sample for accelerator mass spectrometry radiocarbon dating.


Science Learning Hub Survey 2014

Dear Hub visitor,

You're invited to participate in an online survey about the New Zealand Science Learning Hub. This survey was designed to help Hub staff enhance and develop further the site. This is different from our November 2013 survey, so even if you took part in that survey, we would appreciate you taking this survey as well.
