Beginning in marine research

Alvariño’s natural-sciences studies were interrupted by the Spanish Civil War; she completed her degree in 1941. She subsequently joined the Spanish Institute of Oceanography and studied zooplankton at its Vigo laboratory. A 1953 fellowship brought her to Britain for further research and scientific work at sea.

Comparing plankton collections

In 1956 Alvariño went to the United States to work with Mary Sears. Sears subsequently recommended her for a position at Scripps Institution of Oceanography, where she remained until 1969. Collections from different oceans supported detailed comparisons of plankton morphology, classification and descriptions of new species.

Fish larvae and scientific history

Alvariño later studied planktonic fish larvae at NOAA. The Spanish Institute of Oceanography’s biography credits her with describing twenty-two new planktonic species. After her formal retirement in 1987, she continued scientific work and wrote about the history of Spanish marine science.
