Paul A. Falkowski was a renowned American biogeochemist and oceanographer, who made significant contributions to the fields of microbial ecology, biogeochemistry, and astrobiology.
He was notable for his research on understanding the role of microorganisms in the Earth's carbon cycle and for pioneering the field of biophysics.
Falkowski's three greatest contributions to science are:
Falkowski proposed the concept of primary productivity, which is the rate at which photosynthetic organisms convert carbon dioxide into organic matter. This idea revolutionized our understanding of the Earth's carbon cycle and the role of photosynthetic organisms in regulating global climate.
Falkowski discovered a new form of chlorophyll, known as chlorophyll d, which is found in deep-sea cyanobacteria. This discovery expanded our understanding of the
Falkowski was awarded the Tyler Prize for Environmental Achievement for his groundbreaking work in understanding the impacts of climate change on marine ecosystems. His research has provided critical insights into the potential consequences of global warming on oceanic biodiversity and the functioning of marine food webs.
