Meet Graham Blackmore

Why train with me?

Graham holds a PhD in Marine Biology but his love for the aquatic world developed at an early age. He had long been fascinated by the sea and used to spend many hours snorkelling in the UK as a child. By his own admission, Graham grew to regret not learning to dive as an undergraduate but other things got in the way - as a PhD student, however, he leapt at the opportunity!

His first post-doctoral job was investigating snails that eat corals and this allowed him to gain a lot of dive experience. He took up technical diving in order to make the research diving easier and even used CCR to conduct fish census work. Ultimately it wasn't until he found Global Underwater Explorers that he truly understood diving and committed himself to making a career of teaching diving.

Graham is lucky enough to travel the world teaching from basic novice divers all the way up to instructors within GUE. As a passionate diver, he has logged over 3000 dives to a maximum depth of 140m and durations of upto 7 hours. He enjoys reef diving in tropical areas, wreck diving in the English Channel and the Mediterranean and has even been known to occasionally venture into caves. But most of all, he likes being mid water in strong currents with big scenery.
