The relationship between iron and nitrogen fixation in Trichodesmium spp.
… (N) fixing cyanobacteria in tropical and subtropical oceans, regimes frequently characterized by low iron (Fe). Limited information exists about what levels of Fe limit Trichodesmium N fixation. I developed a diagnostic for Fe limitation using quantitative reverse transcription PCR …

Phosphorus physiology of the marine cyanobacterium Trichodesmium
… and nitrogen fixation in the tropical and subtropical oceans. These regions are often characterized by low phosphorus (P) concentrations, and P deficiency of Trichodesmium could limit growth, and constrain nitrogen fixation by this genus. Three key components of P metabolism in …

Protein regulation in Trichodesmium and other marine bacteria: observational and interpretive biomarkers of biogeochemical processes
… phosphate co-stress throughout the tropical and subtropical oceans, demonstrating that this is caused by the biophysical limits of membrane space and nutrient diffusion. Tackling the problem at a smaller scale, I investigated the metaproteomes of individual Trichodesmium colonies captured from a …

Tunnels in the ocean: formation and propagation of interannual water mass anomalies in global subtropical cells
Subtropical cells connect subducting subtropical waters to upwelling sites along the equator. Water mass properties (e.g. salinity, temperature) are set at the surface and subducted along ventilated pathways that flow toward upwelling sites in the tropics. This tight link between the subtropics and …

Validation, trend analysis & bias reduction through satellite fusion of the cloud-top height record from terra MODIS & MISR
… such as rising high-topped clouds and expanding subtropical highs. Since the response in global CTH is the most robust of such responses, accurate estimation of long-term variability in the vertical distribution of CTH on a global scale is important for reducing climate modeling uncertainty and …
