“…15 N substrate additions ( 15 NO 3 − or 15 NH 4 + ; Cambridge Isotope Laboratories) were made with the goal of enriching the ambient pool ~4–10% (Table S2 ). For the NO 3 − -addition experiments, ambient NO 3 − concentrations were estimated using NO 3 − -temperature relationships for California Current waters [ 36 ], while for NH4.1, ambient NH 4 + concentrations were estimated based on historical data from the Southern California Coastal Ocean Observing System (SCCOOS). Incubation bottles receiving 15 NO 3 − or 15 NH 4 + also received NaH 13 CO 3 (Cambridge Isotope Laboratories) according to Table S2 .…”

“…Por esta razón, se debe de tener en cuenta un número mayor de variables climatológicas y oceánicas de acción directa o indirecta en la franja marina costera. Tanto corrientes oceánicas superficiales y profundas como los meteoros locales terrestres, influyen en la distribución de nutrientes primarios, plancton, temperatura del mar, salinidad, etc., y otros agentes involucrados en el medio ambiente costero, que, a su vez se ha constatado que tienen una relación directa con la AS en su comportamiento a mediano y largo plazo (Hernández y Puga 1995;Alfonso, I. et al 1995;Hernández-de la Torre et al 2003;Martín H. et al 2017;Vega-Bolaños et al 2019).…”

“…El régimen cálido se registró a partir de 1977 y continuó hasta 1998, incrementado por los eventos ENSO 1982ENSO -83, 1992ENSO -93 y 1997 que afectaron toda la región de la CC (Parés-Sierra y O 'Brien, 1989;Smith, 1995;Hayward et al, 1999;Moser et al, 2001;Hernández-de-la-Torre et al, 2003;Peterson y Schwing, 2003). El valor medio de P T para el período otoño-invierno en los años ENSO tuvo incrementos antes del evento (-1), debido al parecer a una mayor presencia de nutrientes en la ZE; disminuyó durante el año clave (0) y aumentó aún hasta dos años después (+1, +2) durante los seis eventos registrados en toda la serie de tiempo.…”

“…The warm phase was recorded in 1977 and continued until 1998, increased by the 1982-83, 1992-93 and 1997-98 ENSO events that affected the California Current region (Parés-Sierra and O'Brien, 1989;Smith, 1995;Hayward et al, 1999;Moser et al, 2001;Hernández-de la Torre et al, 2003;Peterson and Schwing, 2003). The mean P T value for the autumn/winter period in ENSO years increased before the event (-1), apparantly due to the greater occurrence of nutrients in the euphotic zone; it decreased in the key year (0) and increased up to two years after (+1, +2) during the six events recorded in the time series.…”
