Abstract
This research focuses on the spatial and temporal distribution of seawater quality factors such as dissolved oxygen (DO), chlorophyll a (Chl-a), salinity and temperature in the Persian Gulf (PG). The samplings were carried out on 11–34 stations during September 2018, May and November 2019. The range and average of Chl-a (μg/l) concentration in the surface waters were 0.04–1.10 (0.43 ± 0.25), 0.02–1.19 (0.46 ± 0.39) and 0.58–1.70 (0.93 ± 0.36) in the summer 2018, spring and autumn 2019, respectively. The cross-section of seawater salinity (psu), temperature (°C) and DO (mg/l) indicated strong stratification during late summer and autumn and vertically well-mixed structures in spring. Frequency distributions of DO at different levels indicated the incidence of a layer of minimum oxygen (0.85 mg/l) at depths below 50 meters in autumn. The distribution of Chl-a was also estimated using the remote sensor Moderate Resolution Imaging Spectrometer (MODIS) during 2018–2019. The results confirmed a significant covariation between remotely-sensed surface Chl-a and in situ data. The results showed that Chl-a was greater in regions nearby the coast compared to open sea regions and also significant impacts of the regional 2019 flooded on the Arvand River catchment.
