Her research interests in climate impacts on marine ecosystems and ocean biogeochemistry have led her to study the impact of UV radiation on phytoplankton photosynthesis in the Antarctic waters, the influence of the Amazon River continuum in biological sequestration of carbon dioxide and the rise of mixotrophy in the Arabian Sea. She uses her diverse expertise in biochemistry, microbiology and remote sensing to develop methods to assess primary productivity both at the cellular level and from space. Dr. Gomes is interested in large-scale climatic questions such as the impacts of the new and unusual planktonic blooms in the Arabian Sea, the effect of Arctic warming and ice melt on the American lobster, the impact of urbanization on wetland systems especially around the Long Island Sound and ocean acidification and deoxygenation of waters from harmful algal blooms.
