TL;DR: Findings indicate that iron limitation can control rates of phytoplankton productivity and biomass in the ocean.
Journal ArticleDOI
Ozone depletion: ultraviolet radiation and phytoplankton biology in antarctic waters.
Raymond C. Smith,Barbara B. Prézelin,Karen S. Baker,Robert R. Bidigare,N. P. Boucher,Teresa L. Coley,D. Karentz,Sally Macintyre,H. A. Matlick,D. Menzies,Michael Ondrusek,Zhengming Wan,Kirk Waters +12 more
TL;DR: Results from a 6-week cruise in the marginal ice zone of the Bellingshausen Sea in austral spring of 1990 indicated that O3-dependent shifts of in-water spectral irradiances alter the balance of spectrally dependent phytoplankton processes, including photoinhibition, photoreactivation, photoprotection, and photosynthesis.
Journal ArticleDOI
Temporal variability of phytoplankton community structure based on pigment analysis
Ricardo M. Letelier,Robert R. Bidigare,Dale V. Hebel,Michael Ondrusek,Christopher D. Winn,David M. Karl +5 more
TL;DR: Results from size fractionation and normal-phase high performance liquid chromatography confirm that Prochforococcus spp.
Journal ArticleDOI
Biological response to iron fertilization in the eastern equatorial Pacific (IronEx II). III. Dynamics of phytoplankton growth and microzooplankton grazing
TL;DR: Mesoscale iron-enrichment of high-nutrient, low chlorophyll waters in the eastern equatorial Pacific clearly demonstrated that phytoplankton growth rates and standing stocks were iron-limited, but the food web also demonstrated a remarkable resiliency to environmental perturbation by establishing a new balance.
Journal ArticleDOI
Spatial and temporal variability of phytoplankton pigment distributions in the central equatorial Pacific Ocean
TL;DR: The results of this pigment study underscore the need for sampling biological properties on appropriate time and space scales, and the necessity of physical measurements for interpreting their distributions as mentioned in this paper, and emphasize the need to sample biological properties at appropriate time-and space scales.
