Analyzing the Mediterranean Sea’s Dynamic Current System and Modeling of Renewable Current Energy Potential

Round 1

Reviewer 1 Report

Overall, the manuscript is not well written. This manuscript focused on the Mediterranean region. It seems that the The new scientific contribution of the manuscript have not been clearly stated. Furthermore, the limitation of the work need to clarify as well. The research methodology has not been clearly outlined. It seems to be data collection only. It is hard to see how the authors obtained the results. They only mentioned the formula (1) originally derived by ref[15].  In my opinion, this manuscript does not satisfy the standard of a peer-review journal article.

(1) Introduction needs to divided into several paragraphs. It is better to point out the research gaps.

(2) Figure 1 may need refernece?

(3) Reference of Equation (1)?

(4) The results presented in Section3 need further clarify and discussed.

Reviewer 2 Report

Please, find all comments in the attached (pdf) file (comments form).

Please, could you send me a final expression (with described term in equation) to calculate the potential energy production per year (based on the speed of the sea current)? This equation can be included and described in paper - instead of equation (1).

Comments for author File: Comments.pdf

In the introductory part of the paper, previous research on the use of sea currents for the purpose of generating electricity is given.
In the second chapter, the goal of the research and the method of analyzing (grouping) the data are presented.
In the third chapter, the data, the speed of sea currents in the Mediterranean Sea, collected using the Copernicus Marine Environment Monitoring Services and the possibility of energy production (electric?) are presented.
In conclusion, the authors determined the possibility of energy production and guidelines for future research.

The interpretation of measurement units should be corrected (kWh is not the same as kW per hour)!

Reviewer 3 Report

The paper discusses the increasing investments in renewable energy, particularly focusing on marine current energy, as a means to reduce fossil fuel consumption and combat the effects of global warming on the marine ecosystem. The study concentrates on the Mediterranean region due to its susceptibility to climate change. It analyzes the current velocity in the region from 2016 to 2018 using remote sensing technology and calculates potential energy production using an underwater turbine system. Findings reveal maximum current velocities of 2.2 m/s in 2016 and 2017, increasing to 2.7 m/s in 2018. Seasonally, current speeds peak at around 2.7 m/s in spring, decrease to 2.0 m/s in summer, rise again to 2.1 m/s in fall, and reach 2.2 m/s in winter. The study suggests that the eastern coastal areas have the capacity to generate approximately 10 GW/h of energy per year using underwater turbine systems. I suggest accept after minor revision.

1. What were the specifications of the selected turbine system, and how were its efficiency and energy production potential determined?

2. How did the current velocities vary spatially across different regions of the Mediterranean Sea?

3. What are the limitations of the current study, and how might they affect the accuracy of the results?
