Eva Álvarez

PostDoc at Istituto Nazionale di Oceanografia e di Geofisica Sperimentale - OGS

ealvarez@NOSPAMinogs.it

Expertise

I am a biologist using ocean models to investigate the role of phytoplankton in the pelagic ecosystem. I parameterize photo-physiological processes relevant to simulate the magnitude and seasonality of primary production. Lately, I have been working with spectrally-resolved models, investigating alternative ways of representing optical variability of the phytoplankton community in ocean models.

Role in project

In SEAMLESS I will be involved in WP6 improving phytoplankton process description (e.g. photoacclimation) and parameter values (e.g. absorption and scattering coefficients) that influence ecosystem primary production.
