I have a broad range of research interests including rocky shore ecology, conservation of tropical marine systems, and biogeochemistry. I am currently investigating sedimentation rates of phytoplankton and the biogeochemical composition of particulate material. I love being outdoors and I am attracted to projects with large proportions of field and lab work.

Composition and sedimentation of marine particulate material

My current research explores the biological carbon pump with a focus on phytoplankton sedimentation, and the composition and reactivity of suspended and sinking marine aggregates. A significant amount of research has been carried out on aggregates collected from sediment traps. Processes occurring within the water column, which can influence the quantity and quality of aggregates reaching depth, and their sinking rates, are less well understood. Specifically, the biogeochemistry of aggregates and associated changes in response to processes in the water column prior to deposition, has received little attention.

My objectives are to...

  • >investigate the seasonal biogeochemical composition of particulate material down the water column profile by collecting suspended particulate material, material from sediment traps, and benthic material
  • >investigate the sinking rates of suspended particulate material, focusing on phytoplankton, using settlement columns
  • >determine the reactivity of the particulate material collected
