The DCIEM (Canadian Defence and Civil Institute for Environmental Medicine) Standard Air Decompression Tables must be used for all Macquarie University diving operations. The full tables can be found in AS/NZS2299.1, Appendix F, Table F1 (A). A short version of the DCIEM tables has been adapted to fit Macquarie University (no-decompression diving only, 30m maximum) and is included in 'diving forms'. A field version of this table is available from the UDO. The DCIEM EANx Tables must be used for all EANx diving operations.
