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.

Membership is open to any interested individuals, or libraries. Currently there are about 250 members worldwide. These include algologists, biostratigraphers, geologists, micropalaeontologists and oceanographers, in both universities and industry. Membership costs 30 per year, and 10 for students. See separate page for payment details.


The INA organizes conferences approximately every two years. The next meeting will be held in Athens in 2017 - convenor Maria Triantaphylou.

Previous conferences have been held in Vienna (1985), London (1987), Florence (1989), Prague (1991), Salamanca (1993) Copenhagen (1995), Puerto Rico (1998) Bremen (2000), Parma (2002), Lisbon (2004), Lincoln, Nebraska (2006), Lyon (2008) and Yamagata (2010), Reston, Virginia (2013) and Bohol the Philippines.

In addition the INA organises occasional workshops and regional meetings, e.g. workshops on Boreal Lower Cretaceous nannofossils (Zurich, 1986), Jurassic nannofossils (London, 1990), terminology (London 1992), extant coccolithophores (Crete 2003 and 2014), Reticulofenestrid coccolith taxonomy (Birmingham 2014, with TMS), regional meetings in Woods Hole, USA (1986), Shanghai, China (1989), Yamagata, Japan (1992), Kuala Lumpur, Malaysia (1994).

Additional European meetings are organised by the nannofossil group of The Micropalaeontological Society (TMS),  since virtually all the TMS nanno group members are also INA hacks these have always felt like INA meetings and following our affiliation with TMS they will be co-sponsored by the INA. Recently we have had excellent joint meetings with the TMS foram group in Copenhagen (2004), Southampton (2005), Liverpool (2006), Angers (2007),  Tubingen (2008), Zurich (2009, a special meeting to mark retirement of Hans Thierstein), London (2010), as part of the International Palaeontological Congress, Krakow (2011), Edinburgh (2012), Prague (2013), Texel (2014), Plymouth (2015/upcoming) See the TMS website for details.

INA Publications

Conference Proceedings

Abstracts from INA Conferences have been published by INA as special issues of the JNR, and its predecessor the International Nannoplankton Association Newsletter. Published proceedings have also been produced from most of the INA Conferences as special issues or volumes of various publications. These are mostly still in print &/or available for download and together form an extremely useful source of literature on nannofossils. For details see: conference proceedings

Journal of Nannoplankton Research (editor: Jamie Shamrock)

The JNR is the journal of the INA. It is produced approximately twice yearly, and serves as a prime means of communication within the field. Circulation is predominantly to INA membership, with useful library coverage. JNR online; articles published in the last two years are available to members only, older articles are open access. See separate page for information for contributors.

INA News in The Newsletter of Micropalaeontology

Following our affiliation with The Micropalaeontological Society, INA News now appears as a separate item in the Newsletter of Micropalaeontology which all INA Members receive. The Newsletter is published twice a year and also carries news on a range of other micropalaeontology activities so we feel this is a major improvement in our services for INA members. Back issues of the Newsletter of Micropalaeontology can be downloaded from the TMS website
