  abstract = {{D}ouble diffusion can result in the formation of thermohaline staircases, typically observed in the ocean interior. {T}he observations presented here were acquired in the ocean surface boundary layer with the autonomous microstructure {A}ir-{S}ea {I}nteraction {P}rofiler. {A}n intense rain event (rainfall rates of up to 35mm/h) resulted in cooler, fresher water (up to 0.15practical salinity unit (psu) over the upper 7-10m) overlaying warmer, saltier water, a situation potentially conducive to double-diffusive mixing. {A}lthough not as crisp as interfaces in the interior ocean because of elevated background mixing, a total of 303 thermohaline interfaces were detected within and at the base of the fresh layer, with mean changes in temperature ({T}) and salinity ({S}) across interfaces of 20 x 10(-3 degrees){C} and 22 x 10(-3)psu, respectively. {T}hese results call for new studies to disambiguate whether such interfaces are formed through double-diffusive mixing or shear instabilities and understand any long-term impacts on near-surface stratification.},
