Can photoinhibition control phytoplankton abundance in deeply mixed water columns of the Southern Ocean? (2010, background): “…under fluctuating irradiance regimes, where peaks in irradiance are related to drops in Fv : Fm (Van Leeuwe et al. 2005; Van Leeuwe and Stefels 2007; Kropuenske et al. 2009) while the qN remains stable (A. C. Alderkamp unpubl.) or changes on a timescale of several hours (L. R. Kropuenske unpubl.).”
Iron‐light interactions differ in Southern Ocean phytoplankton (2012, background): “P. antarctica has been reported to have a photoprotective strategy that relies heavily upon protein synthesis, presumably for the repair of damaged D1 protein within the PSII reaction center (Kropuenske et al. 2009).”
LIGHT‐INDUCED RESPONSES OF OXYGEN PHOTOREDUCTION, REACTIVE OXYGEN SPECIES PRODUCTION AND SCAVENGING IN TWO DIATOM SPECIES 1 (2010, background): “A major mechanism of nonphotochemical quenching involves de-epoxidation of xanthophylls to produce carotenoid species that dissipate the energy absorbed by chl as heat (Olaizola and Yamamoto 1994, Rijstenbil 2005, van Leeuwe et al. 2008, Kropuenske et al. 2009).”
