Research Project: Ocean phytoplankton functional group distribution in data and models

Supervisor: Prof Nicolas Gruber (Eidgenössische Technische Hochschule Zürich)
Secondary Supervisor: Dr Ute Schuster (University of Exeter)
Associate: Dr Meike Vogt (Eidgenössische Technische Hochschule Zürich)

Project Description

A model-data comparison project specifically focussing on phytoplankton dynamics. It will exploit the recently compiled GloPAD phytoplankton database, and use it in conjunction with T2.1 to evaluate ocean model simulations. Phytoplankton assemblages will be derived from the model/data database and the analysis will investigate how oceanographic conditions determine variability and structure in marine ecosystems.
