The International Nannoplankton Association was established in 1977 in order to enhance communication between the widely scattered academic and industrial scientists working on calcareous nannofossils and living coccolithophores. From 2010 the INA has been affiliated with The Micropalaeontological Society. We collaborate on web-hosting and newsletter production and support each others meetings where relevant.
