IPI Intercalibration

Marine Institute-IOC Science and Communication Centre on Harmful Algae International Phytoplankton Intercomparison (IPI) test 2017 in association with NMBAQC

2 June - 15 December 2017, Co. Galway, Ireland

The Marine Institute, Ireland in collaboration with the IOC Science and Communication Centre for Harmful Algae, Denmark will conduct a proficiency test on marine phytoplankton abundance and composition amongst laboratories.
The intercomparison and proficiency test is open for participation for all relevant laboratories globally.
This test will be broken down into two main areas and each participant will be asked to return results for each.
The two areas are:
Identification – in the form of a “Taxonomic Quiz”, This test will be set up on a distant learning web platform called ‘Ocean teacher’. Participants will need to log on with a username and password and answer the questions online.
Enumeration and identification – a number of preserved seawater samples spiked with phytoplankton cultured material or/and natural field samples will be sent to each laboratory. The number and type of samples has not been decided yet and will be adapted to be relevant to the participants.
This year, we were planning on introducing Biovolume measurements as a measure of biomass in the samples to complement the measurements we already take on abundance and composition of marine microalgae in the samples, but first we would like to ask the potential participants whether this new measurement is something their laboratory would be interested in doing and whether it is relevant to their activities.
