30. Concluding Remarks  Operational oceanography requires greater coverage and reliability of altimetry data.  We need to use altimeters to derive oceanic structures on the continental shelf and in coastal regions.  The users do not always realise the importance of altimetry because they are often using derived products.  Thank you for all of the activities and research that have contributed to our understanding of the world’s oceans.
