Profiles of light transmission, disolved oxygen, disolved nutrients,electron transport system (ETS) activity, temperatura and salinity were made in the north Eastern tropical Pacific Ocean. A particle máximum at 150-300 m within the oxygen mínimum and secondary nitrite máximum was associated with the salinity máximum of Subtropical Subsurface Water. A subsurface máximum in ETS activity was als ofound to be associated with the secondary nitrite máximum and the particle maximum. Persistence of these features at a constant depth and their location within a minimum in vertical static stability suggest an advective and/or in situ origin for the particles and an in situ development of the associated chemical and biochemical extremes.
