89 6 Conclusions and Recommendations Substantially increased awareness and availability of reference materials offers many benefits to the ocean sciences. The regular use of such materials can provide a much-needed basis for interlaboratory and international comparison of results, making it possible to acquire accurate, meaningful global data sets that can be used to study problems requiring observations on large space and time scales.

CONCLUSIONS AND RECOMMENDATIONS 95 RECOMMENDATIONS FOR COMMUNITY PARTICIPATION In addition to making new reference materials available to the ocean sciences community, it is essential that a number of other strategies be put in place. These strategies will ensure optimal use of such materials, thus increasing their value to the ocean sciences and justifying this investment.

96 CHEMICAL REFERENCE MATERIALS that round-robin exercises be organized using materials and analytes relevant to the ocean sciences and that laboratories be encouraged to participate, even at an early stage in their experience with the relevant analytical techniques. Encourage Use of New Ocean Science Reference Materials Most of the reference materials proposed in this report are based on natural matrices (seawater, algal cells, sediment)
