The jumbo flying squid (Dosidicus gigas), also known as the Humbolt squid, is an economically important fisheries species in the Eastern Pacific, currently accounting for approximately one third of the world's squid landings.

Understanding the impacts of climate and environmental variability on this commercial marine species is important for fisheries operations and fisheries management efforts. In order to determine the impact of climatic and oceanographic conditions on the spatial distribution of the jumbo flying squid fishery in the Southeast Pacific Ocean, Yu et al., (2017) mapped sea surface temperature and sea surface height data from NOAA OceanWatch Central Pacific node and chlorophyll-a data from the Asia-Pacific Data Research Center at the University of Hawaii with commercial fisheries data.

The researchers analyzed the data to identify the environmental conditions that were most favorable for the squids and use this information to explain observed movements of the fishing ground.
