Brad Mardell **comes** from New Zealand and he's a marine biologist. He **works** in an office at his university, but he **spends** a lot of time there. He **likes** being under the water because he **studies** animals in the sea. Brad is married and his wife, Gina, **goes** with him on expeditions. But she **does not spend** under the water because she **sails** the boat. 'We're a good team,' says Brad.
