Hannah Robson writes: I'm working on a BBC Television series about different marine environments in which we filmed underwater in a number of locations around the world. For one of our films in the series we travelled to the Gulf of California where we encountered a large pod of common dolphin, which we were able to film. I'm looking to find out what is known about population figures for common dolphin in this sea. Are numbers declining or increasing? Is there any indication that the marine protected / conservation areas are protecting the population. I'm be really grateful for you any information you have. With many thanks and all the very best Hannah Robson Oceans BBC Science Room MC5D4 BBC Media Centre 201 Wood Lane London W12 7TQ Tel: +44(0) 208 008 0535 E-mail: hannah.robson@bbc.co.uk
