Samantha Lavender

Research interests

Dr Samantha Lavender has over 15 years research experience. Her research interests have focused primarily on the quantitative remote sensing of water bodies using their colour signature. Often called ocean colour, it’s used to quantify and concentrations and behaviour of what’s dissolved or suspended by modelling the optical properties. Research extends from the movement of sediments in the coastal zone to phytoplankton in the open ocean. Both topics link to wider issues, such as climate change, as remote sensing is an important monitoring tool. . She is also Chairman for the Remote Sensing and Photogrammetric Society and, at an international level, co-chair of the International Society for Photogrammetry and Remote Sensing Working Group VIII.7 (Oceans). Previously she was a committee member on the International Ocean Colour Coordinating Group (IOCCG).

Other research
 ARGANS (Applied Research in Geomatics, Atmosphere, Nature and Space) Limited is an independent customer-oriented industrial company of highly skilled and innovative scientists and engineers bringing state of the art research to solve industrial, operational and scientific requirements. It was established as a Private Limited SME Company in the United Kingdom in 2007. The shareholders include ACRI-ST (France) and the University of Plymouth, and its Managing Director is Dr Samantha Lavender. The operational base is the Tamar Science Park, which allows ARGANS to make the most of the support for and links with marine activities within the South West.
