in 1999 he was awarded the medal of the order of australia (oam). david held the youngest (assisted) solo circumnavigation record for 13 years, from 1996 to 2009. by some accounts he still holds the unofficial record for the youngest solo "non-stop" assisted circumnavigation. jessica watson captured the unofficial youngest age record in may 2010 with an unassisted solo circumnavigation, but her course did not meet the minimum orthodromic distance requirement of 21,600 nautical miles set by the wssrc. jesse martin completed a solo non-stop unassisted circumnavigation in 1999, he was 24 days older than dicks at the completion of dicks' voyage.

one of the most important information we can get from detrital zircon ages is the maximum depositional age of the referring sedimentary unit. the sedimentary unit cannot be older than the youngest age of the analyzed detrital zircons because the zircon should have existed before the rock formation. this provides useful age information to rock strata where fossils are unavailable, such as the terrestrial successions during precambrian or pre-devonian times. practically, maximum depositional age is averaged from a cluster of youngest age data or the peak in age probability because the youngest u-pb age within a sample is almost always younger with uncertainty.
