Mae Kevin Hawke yn blymiwr brwd ac yn wirfoddolwr gyda'r prosiect Moroedd Byw /Living Seas. Cafodd y ddelwedd hon ei chymryd o'i lyfr log ac mae'n cofnodi plymio yn Martin's Haven ar 21ain Orffennaf 1996. Pan oedd wrthi'n plymio fe sylwodd ar amrywiaeth o fywyd gwyllt morol sy'n cael eu disgrifio ganddo yn yr adran "Dive Details" o'r lyfr log (trawsgrifiad isod).
Dive Details: Short surface swim to get a bit of depth for descent. Good visibility lots of kelp but still lots to see. Variety of things? growing on the kelp at first, then swam over sandy area lots of fish - young Pollack etc. Also a variety of shellfish, crabs and razor fish about. Peter checking direction of travel on my compass - I wish I knew how? Good control of buoyancy John bobbing a bit up & down. Quite a log dive and only a little air eventually surfaced with only a few bars remaining.
