Fish Larvae Response to Biophysical Changes in the Gulf of California, Mexico (Winter‐Summer)

open access: yesJournal of Marine Sciences, Volume 2013, Issue 1, 2013., 2013
We analyzed the response of fish larvae assemblages to environmental variables and to physical macro‐ and mesoscale processes in the Gulf of California, during four oceanographic cruises (winter and summer 2005 and 2007). Physical data of the water column obtained through CTD casts, sea surface temperature, and chlorophyll a satellite imagery were used
