Port Jackson

SCUBA observations show that Port Jackson sharks repeatedly visit specific resting sites on ocean reefs at South Bondi (New South Wales) and, when disturbed, move directly from one site to another. The sharks also use specific resting sites in Sydney Harbour and, when transferred by boat to different localities within the harbour, up to 3 km away, return to their original resting sites. The sharks migrate from as far south as Tasmania to Sydney Harbour to lay their eggs in specific sites. Speculative extrapolation from the above observations suggests that Port Jackson sharks must have a highly developed spatial memory.

Induced Changes

Atmospheric 14C variations in nature, as previously documented for the Southern Hemisphere by studies carried out in South Africa and New Zealand, were supplemented by 14C concentration measurements of wheat-grain samples collected in southeastern New South Wales. Our measurements cover the critical period of 1945/46 up to 1956/57, and span the transition of Suess and atom-bomb effects. The observed variations can be followed quite precisely in the peat deposits of the Bega Swamp, New South Wales, and indicate that vertical mixing of organic components within the peat is negligible. Pollen analytical data covering the last 400 years also show that the peats act as efficient traps; thus, time-precise zonations can be identified, and historically documented man-induced changes in pollen assemblages can be correlated with 14C ages in recent times.
