"The most compelling message in the world is almost useless if the only people hearing it are people who already agree with you". - David Westcott, Director of Digital Strategy at APCO Worldwide.

Whether an Instagram of sea ice, a tweet about the latest science paper, or a long Google+ post, my social media activities intend to bring the wonders of the ocean - and the latest scientific thinking - to people across the globe.Some of my followers love the natural world, some are concerned citizens, some a seeking new knowledge, some seeking to share knowledge. Some are scientists, some policy makers, managers, businesses or industry. Some have never even seen the ocean for themselves.

The diversity of social media audiences inspires lively debate - both in public and 'behind the scenes'. Take a peak at on your favourite social media platform - and if you have something to add, something to ask, join in.
