英文摘要The barrier layer (BL) is an expansive halocline layer commonly found in the western equatorial Pacific, long been thought to inhibit entrainment of colder thermocline water into the surface mixed layer (ML), consequently facilitating the development of El Nino. But here we find frequent turbulent mixing in the BL from both direct turbulence measurements and indirect mixing estimates within an 11-year-long Argo profile data set. The observed BL mixing is as strong as in the ML, yielding effective heat transfers across the isothermal layer (IL) base. The estimated BL mixing is ubiquitous, with occurrence ranging 20%-60% spatially and peaking at around 160 degrees W, 0 degrees N; it occurs more frequently in La Nina than El Nino years. The BL mixing is associated with thicker ML, BL, and IL, weaker BL stratification, and lower temperature and higher salinity in the IL. How the BL mixing may impact the El Nino development deserves further exploration.
