Rising levels of atmospheric C02 lead to acdification of the ocean and alter seawater carbonate chemistry, which Exposure of the juvenile oysters to elevated PCO2 and / or low salinity led to a significant increase in The critical salinity seems to be about 35 parts per thousand, which is approximately the average for the ocean. The calcium carbonate content of the sediments likewise increases as the temperature increases and as the depth decreases. Salinity affect the influence of increasing CO2 on oceans or lakes. Seawater with low salinity holds more gas than high salinity water. For details consult https://pubs.usgs.gov -- report and https://www.sciencelearn.org.nz
Evidence that the world’s water cycle has intensified is contained in 2010 research published in the American Journal of Climate. According to this study, co-authored by CSIRO scientists Paul Durack and Dr Susan Wijffels, the surface warming we have seen over the past 50 years has penetrated deep into the ocean.
According to Richard Matthews, the salinity of the oceans is connected to CO2. Changes in the salinity of the oceans contribute to global changes in carbon dioxide as waters with more saline are less soluble to carbon dioxide.
Dear Agam Gwalia,
Actually, Yes, as mentioned by Sylvester Peter Antai, there is a possibility to precipitate CaCO3. I think that we have to think about the equilibrium in the answer given in the link below.

They are negatively related the solubility of CO2 decreases at higher salinity. This is true for all other atmospheric gases like O2, N2 etc. This is mostly because of the effects of ionized salt species in seawater.
