"From an early age I was fascinated by the sea and the way it is driven by the ever-changing weather. Working at PML nearly 25 years has deepened my interest and understanding of the marine environment and I consider myself privileged to be able to continually ask different questions about how things work; and sometimes coming up with the answers."
Dr Tim Smyth is the Head of Science for Marine Biogeochemistry and Observations at PML. This involves leading a team of around 20 people ranging from PhD students to experienced senior scientists across a range of disciplines from air-sea exchange, nutrient cycling to molecular science within the broad remit of marine biogeochemistry. His brief also includes oversight of the Atlantic Meridional Transect (AMT) as well as the Western Channel Observatory (WCO: both NERC National Capability) which he has been leading for the past 15 years.
Since joining PML in 1997 as a data analyst and algorithm developer for the then newly launched SeaWiFS ocean colour satellite, his research interests have broadly encompassed theoretical and experimental atmospheric and in-water optics. He has a strong interest in developing innovative technologies for automated marine measurements including the WCO buoys, ship emissions and atmospheric aerosols.
He has around 280 days of sea-going experience including being Chief Scientist on two Atlantic Meridional Transect (2014, 2015) expeditions between the UK and Falkland Islands.
He has over 100 peer-reviewed ISI papers.
