“…A patch of high saline water (above 36 on average; see Figure 9(c)) is observed in this region during the entire period. e presence of this high saline water near the Ras al Hadd region indicates the intrusion of highly saline water from the Persian Gulf into the northern Arabian Sea via the Sea of Oman [39]. However, the wind speed shows an increasing trend during the summer monsoon (Figure 10(a)).…”

“…Upon the arrival of the summer monsoon, SST warms up to 31°C in August 2016 and June 2017 with SSS above 36.2 each (see Figure 12(d)). e presence of high salinity water (>36.5) in the Sea of Oman is most probably due to excess evaporation over precipitation and highly saline water intrusion from the Persian Gulf during the summer monsoon ( [39]; see Figure 13(d)). e postmonsoon period in this region is characterized by the departure of the summer monsoon, having almost similar characteristics of surface forcing as that of premonsoon.…”

Sea surface temperature (SST) and isothermal layer depth (ILD) are important oceanic parameters and could play a significant role in understanding the upper thermal structure as well as improve the predictive capability of monsoons in the tropical oceans. In a disparate departure from the past research, the present study investigates the seasonal variability of SST and ILD in association with the monsoon cycle in the Arabian Sea and Sea of Oman regions by examination of Argo datasets for 2016-17. In this study, the ILD climatology is determined from temperature profiles provided by the Argo floats based on a threshold technique T z ≥ SST − 1 ° C to investigate the region of stronger and weaker monsoon wind forcing. For SST, values of temperature are used nearest to the sea surface (depth z ≤ 5 m). The region is split into four distinct zones for an accurate description of the monsoon cycle: the south Arabian Sea, the central Arabian Sea, the north Arabian Sea, and the Sea of Oman. It is observed that summer monsoon is more pronounced in the south-central basin of the Arabian Sea, where ILD is deepening (>100 m in September 2016) mainly due to stronger wind forcing in this region. On the contrary, the Sea of Oman region is displayed with smaller ILD amplitude (<10 m in June 2016) with larger SST, meaning that this region is weakly influenced by the summer monsoon. The seasonal relationship established between ILD variability and monsoon cycle for 2016-17 shows that ILD could be a useful indicator for predicting summer monsoon in the Arabian Sea regions. Our analysis results indicate that the dynamics for SST variability are different in these regions and are influenced either by large-scale atmospheric forcing, such as the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD), or by the effects of mesoscale variations occurring along the Oman-Arabian coast.

“…The authors also showed that weaker density variations existed below 400 m with the same temporal behavior as in the upper layers. Using the Argo data, Khan et al demonstrated the existence of a patchy PG outlet in the GoO which emerged in the western part of GoO from March to November and attained a maximum stage in August [37].…”

A combination of multiple data sources has been used to study the characteristics of internal solitary waves (ISWs) in the Gulf of Oman (GoO). Water column stratification in the Gulf has been examined using field observations and World Ocean Atlas 2018 datasets. The spatiotemporal distribution of ISWs has been obtained from satellite images obtained by means of Synthetic Aperture Radar (SAR) and optical sensors taken from 2018 to 2020. The mechanisms of ISW generation in the GoO have been studied using the data revealed from different available sources. The results show that there are annually two major typical stratifications in the GoO throughout the year, strong stratification in May through September and weak stratification during other months. Dispersion relations corresponding to these types of stratification have been obtained with acceptable accuracy for both deep and shallow regions. The spatiotemporal distribution of ISWs demonstrates that the western and southern regions of the GoO are the hotspots for generation of ISWs in this basin. Several mechanisms of ISW generation in the GoO are discussed including tide, eddies, lee waves, and atmospheric perturbation; the latter one is, apparently, responsible for the appearance of large-amplitude ISWs.
