For Smithsonian Institution senior research scientist David Pawson the mysteries and wonders of marine life began to spark his imagination when he swam and fished off the Napier beach back in the 1950s.
Now he is set to return to his old seafront stamping grounds and is scheduled to deliver a talk on New Zealand deep-sea exploration between 1865 and 1965 at the MTG Century Theatre on Sunday, March 23.
While he has been with the US-based Smithsonian Institution's National Museum of Natural History since 1964, Mr Pawson has travelled and explored the oceans widely and has maintained research programmes in New Zealand.
His talk will draw on knowledge of New Zealand deep-sea research, including his personal experiences in the late 1950s and early 1960s, as well as accounts of many of his expeditions - some involving Hawke's Bay.
"Exploration of the deep sea is always exciting and sometimes dangerous - especially in the New Zealand region."
