Hydrology of the seas around the Sardinia, western Mediterranean
Abstract. The presence and interannual variability of water masses on the continental shelf surrounding the island of Sardinia are described from three multidisciplinary cruises carried out in September 2019, late August 2020 and September 2021 in the framework of the IDMAR project. A multiparametric probe acquired CTD data along vertical profiles at a total of 166 casts located from the near-shore to the continental slope, between the surface and 300 m depth. The analyses of these observations are for the first time identifying the water mass phenomenology on the Sardinia shelf characterized by the presence of the Atlantic Water at the surface. It shows an unusually low salinity < 37.0 at 35 m on the south-western approaches, detected during the cruises in 2019 and 2021, and driven by the Algerian eddies. On the southern and eastern shelf, the presence of the Atlantic Water is marked by a salinity of about 38.0, and the water column is affected by the temporal and spatial variability of the South East Sardinia Gyre. These observations are opening new aspects to understand the long-term evolution of the hydrology around Sardinia in the context of the general circulation of the Western Mediterranean basin.

RC1: 'Comment on egusphere-2023-2193', Anonymous Referee #1, 17 Nov 2023
Hydrographic data from three research expeditions in three consecutive years are analysed and show the water mass characteristics around Sardinia. Additional analysis is provided with respect to inter-annual variability by comparing potential temperature and practical salinity values from the research expeditions.
I have several major concerns with this manuscript. The manuscript lacks a clear storyline and appropriate argumentation. In general, there is no reasoning given why it is relevant/important to investigate this region other than these are new data of three consecutive years. Furthermore, there is too much speculation with respect to the results in this manuscript. For some of the conclusions made, there has not been given any evidence to support these statements. For example, when the author relate sea surface temperature to coastal upwelling events, but do not consider wind speed, wind stress curl or Ekman transport.
With respect to minor points, all figure captions are incomplete and lack neccessary information (independently from the text) to fully understand what is displayed. For some of the data shown no reference is provided, nor is there information from where these data originate. The colorbars of the figures are unsuited for colorblindness. The text and description of results is very inconsistent and thus very hard to follow. For example, in the text the potential temperature is defined as T (in oceanography defined as theta), then in figure 3 it is theta and then later in the paper it is referred to as temperature. Numbers and values are not rounded consistently, sometimes rounded to 2 and sometimes rounded to 3 digits.
After careful consideration, I am rejecting this manuscript in its current stage, as it does not meet Ocean Sciences standards. I do see the potential in these data sets, but a more careful analysis, reasoning, detailed discussion and argumentation is essential. The amount of work needed to extend the analysis and results incorporated in this manuscript will take longer than the timeframe given for major corrections, but I strongly encourage the authors to continue to improve this manuscript. I have attached a pdf-file with detailed comments that hopefully help the authors to understand the main issues and address questions.

We are sorry that our manuscript was rejected but we realize several errors that we missed during the preparation of the submitted version and other shortcomings.
So we thank the referee for his comments that will allow us to improve the work which will be resubmitted once all suggestions are resolved and after extensive review by the authors.Citation: https://doi.org/10.5194/egusphere-2023-2193-AC1

One review was received, which advised rejection of this manuscript. A second review is not available yet. A second review will not substantially change the final decision. The authors (see author comment) agreed to revise the manuscript thoroughly for a new submission in the future.
