Características químicas de las masas de aguas costeras ecuatorianas, durante el evento "La Niña" 1999-2000

El objective of this article was to show the impact of a cold phenomenon such as "La Niña" during a multi-year period. The study was conducted by measuring the chemical characteristics of masses of water and comparing them to the characteristics shown in 2000 where the activity of this phenomenon was the strongest. The masses of water were located based on their characterization with parameters such as temperature, salinity, dissolved oxygen and inorganic micronutrients (phosphates, silicates, nitrites, and nitrates). These parameters were measured in 1994, a year considered as normal activity and in those years where "La Niña" was observed with greater intensity. The masses of water ATS, AES, ACP, AESS were established during the years of analysis. The different water masses had more oxygenated, nutrient rich, during the development of "La Niña", that in neutral year.
