Over 4000 m Down

Deep sea discoveries never fail to amaze me, and this one of a coral that lives on metal deposits is extra special.

Sometimes my job involves flying to distant places and for my recent trip to Panama for the sail training charity Seas Your Future, I sought to find out about the fuel consumption and carbon footprint for different routes…. Read More
