Condiciones hidroquímicas del mar peruano durante el otoño 2016. Puerto Pizarro – Casma, BIC Humboldt 1605-06

Abstract

Se informan los resultados sobre oxígeno disuelto y nutrientes, obtenidos durante el crucero del 24 de mayo al 16 de junio 2016 frente a la costa peruana, hasta 100 millas náuticas. El informe está enfocado a relacionar las condiciones hidroquímicas con los recursos demersales. La distribución de la zona de mínima de oxígeno se localizó a mayor distancia de la plataforma continental entre Pimentel y Malabrigo, a diferencia de la zona norte donde se encontró a menor distancia de la plataforma continental.

ABSTRACT: This study presents the findings on dissolved oxygen and nutrient levels gathered during a research expedition conducted from May 24 to June 16, 2016, along the Peruvian coast, spanning up to 100 nm offshore. The primary focus of this report is to establish a correlation between hydrochemical conditions and demersal (bottom-dwelling) marine resources. Notably, the distribution of the oxygen minimum zone was observed at a greater distance from the continental shelf between Pimentel and Malabrigo. This pattern contrasted with the northern region, where the oxygen minimum zone was found closer to the continental shelf.
