There is now no wind park operating along the Egyptian Mediterranean Coast, hence the goal of this study is to find some ideal circumstances for such projects. In order to fulfill this aim, wind data from five coastal meteorological stations were used for the evaluation. These are, respectively from west to east, Mersa Matruh (MM), Ras El-Tin (RE),...

This work investigates the impacts of the recent development processes on the temporal and spatial sea-level variations along the Suez Canal. Hourly sea-level data were collected at three locations representing the northern (PF), central (I) and southern (PT) regions of the Canal. The data extended from June 2010 to July 2015. The T_Tide package wa...

Heavy metals entering seawater pose a global threat to marine life and the ecological system. In this regard, this study investigates the mass balance of copper in Abu Qir Bay, a shallow basin located in the western Mediterranean coastal zone of Egypt. The study area is well-thought-out as a fertile marine habitat, which emphasizes the presence of...

Extreme events such as Marine Heat Waves (MHWs) and Low Chlorophyll-a (LChl-a) in the ocean have devastating impacts on the marine environment, particularly when they occur simultaneously (i.e., the compound of MHWs and LChl-a events). In this study, we investigate the spatiotemporal variability of MHWs and LChl-a events in the Arabian and Omani Gu...

Marine heatwaves (MHWs) have recently been at the forefront of climate research due to their devastating impacts on the marine environment. In this study, we have evaluated the spatiotemporal variability and trends of sea surface temperature (SST) and MHWs in the Black Sea. Furthermore, we investigated the relationship between the El Niño–Southern...

We investigate the monthly mean sea level fluctuations in the Eastern Mediterranean Sea from 1923 to 2019. The data provided by Permeant Service for Mean Sea Level (PSMSL) is used to analyze the long-term variations of sea level. The analyses use PSMSL monthly mean sea level time series at sixteen tide gauge (TG) stations in six countries. The long...

The study of heat and water fluxes is one of the most essential components for understanding the interactions and exchanges between the ocean and atmosphere. Heat transfer across the air-sea interface is an important process in ocean-atmosphere dynamics. In this study, a 40-year (1981-2020) high-resolution (0.25 • × 0.25 •) ERA-5 reanalysis dataset...

The current research focuses on a thorough sea level analysis in Mersa Matruh. Hourly sea level observations from 18th January, 2004 to 31st December, 2004 are used in the study. The T_Tide package is applied to obtain the different tidal constituents and the residuals. Results reveal a mean sea level of 53.6 cm. The present study indicated that th...

Marine heat waves (MHWs) can have catastrophic consequences for the socio-environmental system. Especially in the Red Sea, which has the world’s second longest coral reef system. Here, we investigate the sea surface temperature (SST) variability and trends, as well as the spatiotemporal characteristics of marine heat waves (MHWs) in the Red Sea, us...

Marine heatwaves (MHWs) can cause devastating impacts on marine life. The frequencyof MHWs, gauged with respect to historical temperatures, is expected to rise significantly as theclimate continues to warm. The MHWs intensity and count are pronounced with many parts of theoceans and semi enclosed seas, such as Eastern Mediterranean Sea (EMED). This...

Water temperature, salinity and conductivity profiles were obtained at each location during the mobilization, service visits and final recovery from February, 1999 to January, 2000. A Seabird 19 CTD recorder was used to obtain data at regular intervals throughout the water column from 1m below the surface to the seabed. The instrument was set up to...

Numerical simulations of water circulation were achieved for Egyptian Mediterranean shelf and Levantine basin with different resolutions. The coarser resolution model for Levantine basin has horizontal resolution 5` min., while, the finer one for the Egyptian coast was 2` min. interval. The bathymetry of the Levantine basin was taken from MODB data...

Numerical simulations of water circulation were achieved for the Levantine basin using a three-dimension hydro-dynamical model. The bathymetry of the Levantine basin was taken from MODB dataset. The initial fields for temperature, salinity and current used to setup the model were taken from MODB dataset. The surface momentum, heat and fresh water f...

The water circulation along the Egyptian Mediterranean Coast was studied using three-dimensional numerical model. Numerical simulation was achieved using the Princeton Ocean Model (POM) with horizontal resolution of 2` grid interval and 14 vertical sigma levels. The bathymetric map of the Egyptian coast was digitized with high resolution from the A...
