She is mostly interested in studying the ecology of phytoplankton in the world’s oceans by using a combination of in-situ taxa-specific biomass measurements and information on ocean optics and remote sensing of ocean color. Dr. Lange has a particular interest in assessing phytoplankton organisms from many different points-of-view (taxonomic, physiological, biogeochemical and ecological), using diverse tools (from microscopy to remote sensing) to understand what regulates the distribution, diversity and biomass of these marine microscopic primary producers in the ocean, in order to understand how they affect marine life and biogeochemical cycles in diverse environments, from polar areas like Antarctica to the tropical regions like the ocean gyres.
Dr. Lange was a marine biologist and science teacher (UFRJ, Brazil), and earned her MSc in Biological Oceanography (FURG, Brazil) and PhD in Earth Sciences (University of Oxford, United Kingdom). Her teaching experience was mostly focused on elementary and high school students, whereas her research experience has been devoted to studying marine phytoplankton. During her undergraduate and MSc courses, she studied the ecology and diversity of microphytoplankton in Antarctic coastal areas and how it is influenced by environmental factors like glacier melting and shifts in winds and seawater temperature. The projects had the support of the Brazilian Antarctic Program and contributed to the Census of Marine Life. After that, she participated on the NF-POGO Training Course in Operational Oceanography (BIOS, Bermuda), where she first learned about ocean optics. During her PhD, she used remote sensing of ocean color and flow cytometry to study the variability of the different groups of picophytoplankton in the Atlantic subtropical gyres using satellites. Dr. Lange is currently part of the PACE project (Plankton, Aerosol, Cloud, Ocean Ecosystem) from NASA, working on the development and evaluation of algorithms that can use hyperspectral ocean reflectance (ocean color) information to estimate the contribution of major phytoplankton functional types in the world’s oceans.
