IOCCP and JAMSTEC are pleased to announce the 4th Intercalibration Exercise for Nutrients

IOCCP and Japan Agency for Marine-Earth Science and Technology (JAMSTEC) have invited more than 80 laboratories worldwide to participate in the 2014 inter-comparison study designed to test the global comparability of nutrient measurements and to promote the use of CRM of nutrients in seawater. 

 

The oceanographic community has continued to improve comparability of nutrient data from the world's oceans in many ways, including through 3 international inter-laboratory comparison studies since 2003 and the development of nutrient reference materials (RMs). However, adequate comparability and traceability of nutrient data have not yet been achieved.

 

Certified reference materials, CRMs, of nutrients in seawater that cover wide range of nutrients concentration became available in 2014. IOCCP and JAMSTEC decided to continue and expand the intercomparison study using both RMs and newly arrived CRMs. Invited laboratories will confirm their participation by 30 November 2014 to allow for somple shipment by the end of the year. Reporting deadline for analyses' results was set to 28 February 2015 and we hope to be able to report integrated findings in mid-2015.
