Sampling Location: Jeddah Coastal Waters, Red Sea Coast
Institutional Affiliation: Marine Science Research Center
Filing Location: Saudi Arabia Jeddah

This report details a comprehensive oceanographic field study conducted along the eastern coast of the Red Sea, specifically within the metropolitan waters of Oceanographer research stations. The primary objective was to assess baseline hydrographic parameters, including salinity profiles, temperature gradients, and dissolved oxygen concentrations. Given that Saudi Arabia Jeddah serves as the Kingdom's principal gateway to the Red Sea and a hub for rapid urban expansion and marine infrastructure development, understanding these oceanographic variables is critical. The data collected herein provides essential insights into local water column stability and potential anthropogenic impacts on the marine ecosystem.

1. To measure vertical profiles of temperature and salinity (T-S diagrams) to identify stratification layers.
2. To determine the spatial distribution of dissolved oxygen in surface and deep waters near Jeddah.
<3. To assess turbidity levels as an indicator of sedimentation from coastal urbanization.Oceanographer teams.

All fieldwork was executed using a calibrated Conductivity, Temperature, and Depth (CTD) rosette system deployed from a research vessel anchored approximately 5 nautical miles off the coast of Saudi Arabia Jeddah. The deployment site was selected to represent both nearshore influences and open Red Sea characteristics. Additionally, Niskin bottles were used at specific depths to collect discrete water samples for laboratory analysis of nutrient concentrations (nitrates, phosphates) and chlorophyll-a levels.

The Oceanographer team utilized standard protocols established by the Intergovernmental Oceanographic Commission. All instruments were calibrated prior to deployment according to manufacturer specifications. The geographic coordinates for the sampling station were recorded via GPS with an accuracy of ±1 meter. Water samples were preserved in amber glass bottles immediately after collection and stored at 4°C until analysis back at the laboratory facilities.

Temperature and Salinity Profiles

The CTD casts revealed a distinct thermocline layer beginning at approximately 50 meters depth. Surface temperatures ranged between 28.5°C and 29.1°C, consistent with typical seasonal averages for the Red Sea during autumn months in Saudi Arabia Jeddah. Salinity values near the surface were recorded at an average of 39.2 PSU (Practical Salinity Units), increasing slightly to 39.5 PSU at depth due to high evaporation rates characteristic of this semi-enclosed sea.

Dissolved Oxygen and Nutrients

Dissolved oxygen concentrations showed a minimum zone at depths between 200 and 400 meters, a common feature in Red Sea hydrography. Near-surface oxygen levels were saturated (115%), indicating healthy gas exchange with the atmosphere. Nutrient analysis indicated low nitrate and phosphate levels in surface waters, typical of oligotrophic environments, though slight elevations were noted near riverine discharge points closer to the Jeddah shoreline.

Turbidity Measurements

Turbidity was highest in the immediate coastal zone (0-10 meters), averaging 4.5 NTU (Nephelometric Turbidity Units), likely due to resuspended sediments and urban runoff. Open water samples showed significantly lower turbidity, measuring less than 1 NTU.

The hydrographic data collected during this expedition aligns with historical records maintained by oceanographic institutes in the region. However, recent trends suggest a gradual increase in surface temperatures and localized fluctuations in salinity, potentially linked to climate change and increased urban development along the coast of Saudi Arabia Jeddah.

As an Oceanographer analyzing these results, it is crucial to interpret these findings within the broader context of marine conservation. The slight elevation in nutrients near the shore warrants monitoring, as excessive nutrient loading can lead to eutrophication and harmful algal blooms, which threaten both marine life and public health.

The stratification observed in the water column plays a vital role in limiting vertical mixing, thereby affecting the distribution of heat and oxygen. This stratification is intensified during summer months but remains significant year-round. For scientists working to protect the Red Sea ecosystem, understanding these dynamics is essential for modeling future changes and implementing effective environmental policies.

This lab report confirms that the waters adjacent to Saudi Arabia Jeddah exhibit stable oceanographic conditions typical of the northern Red Sea. The data collected provides a robust baseline for future studies. Continued monitoring by Oceanographer teams is recommended to track long-term trends in temperature and salinity, particularly in light of ongoing urbanization and climate variability.

The findings underscore the importance of maintaining rigorous environmental standards in coastal development projects. By prioritizing data-driven oceanographic research, stakeholders can ensure the sustainable management of marine resources for future generations.

1. Establish a continuous monitoring buoy network along the Jeddah coast to provide real-time oceanographic data.
2. Increase frequency of CTD casts during seasonal transitions to capture dynamic changes in water column structure.Oceanographer professionals globally.
