Anthony Cossio

Operations Research Analyst

Anthony Cossio is an Operations Research Analyst in the Antarctic Ecosystem Research Division (AERD). He conducts research on population dynamics and ecology of Antarctic krill and other species of interest using active acoustics. Since joining AERD in 2004 he has supported the division with ship logistics, acoustics, and most recently, underwater gliders and moorings.
