Carbon dioxide and Oxygen in the ocean are extremely different from the atmosphere.
The reason is defined by Henry's law, which sees the amount of gas dissolved in a liquid depending on its pressure, temperature and salinity of the liquid. With the increase in pressure and the decrease in temperature and salinity, the solubility of a gas increases. The solubility also depends on the properties of the gas itself.
The inorganic cycle of CO2 in water is of extreme importance, as it regulates the carbonate cycle. Calcium carbonate is the main element that constitutes the shell of many small organisms of the zooplankton (if you like, the cycle is illustrated in the picture above).
The oxygen present in seawater is lower than in the atmosphere (approximately 6%), while CO2 is much higher, with values of 0.04% in the air and 84% in the sea.
These data are essential for understanding the functioning of the marine ecosystem. In fact, erroneously from what is commonly thought, it is the phytoplankton present in the sea that produces the majority of the oxygen present. In fact, it is estimated that about 70% of oxygen is produced by phytoplankton. However, the percentage is highly variable, due to the difficulty of obtaining a single long-term data, as the quantities of phytoplankton and the consequent oxygen produced vary greatly throughout the year. Another fact of particular interest is that the oceans, thanks to the high solubilization capacity of CO2, have been able to store about 40% of the CO2 produced by man in the last 200 years.

Have you ever seen this plant washed up on a beach or underwater?
If you are from the Mediterranean region, most probably yes. But you might have thought it was an alga. Especially because not many people know that there are marine plants. They are called marine phanerogams or seagrasses and is possible to find them worldwide, with around 72 species recognised.
A curious fact about these plants is that they evolved back from land plants and not viceversa!
𝘗𝘰𝘴𝘪𝘥𝘰𝘯𝘪𝘢 𝘰𝘤𝘦𝘢𝘯𝘪𝘤𝘢 is an endemic species of the Mediterranean and is mostly disappeared, still living in a few small patches.
