Scubazoo cameraman Roger Munns has recently returned from a 6 week filming trip for the BBC's latest Natural History series - Life

For starters this was a huge trip in terms of length of time, distance traveled and what we were trying to achieve photographically. We covered over 6500KM's in the course of the six weeks with most of that being in open ocean. Indeed one of the few islands we sighted along the way, Bouvet, is famous for being the most remote island on Earth - more than 1500km's from the nearest land mass. The brief for the topside cameraman (Nick Guy) and I was too shoot a sequence involving a swarm of Antarctic Krill (Euphasia superba) at the surface. The hope was that a large swarm of Krill at the surface would attract predators such as Seals, Penguins and Baleen whales and develop into a 'baitball' .

Unfortunately Krill are diurnal and are only usually found at the surface during hours of darkness but in the past swarms have been seen infrequently during daylight. The hope was that by catching a ride with a Scientific vessel conducting a survey in the Southern Ocean we may spot such a swarm and be able to get footage of this never before filmed event.

As it turned out luck was against us and despite our best efforts no Krill were encountered above 10m in the water column. However we did get the chance to get in the water with fur seals amongst the kelp in South Georgia and also freedive with humpbacks around an iceberg in the open ocean. On top of that there was the opportunity to spend a day in South Georgia where we had the chance to shoot stills of the local wildlife, visit Grytviken whaling station, the grave of Sir Ernest Shackleton and enjoy the hospitality of the British Antarctic Survey scientists based on the island.

Once we were out of the cooler waters and our chances of finding Krill had evaporated, Nick and I filmed and edited a short film for the scientists on board which occupied us nicely until we got to Capetown.
