An area of the ocean with very low oxygen levels is called a "dead zone." Dead zones are often caused by excessive nutrient runoff from land, which leads to algal blooms. When these algae die and decompose, they consume oxygen in the water, creating hypoxic conditions that can be harmful to marine life.
Bogs have oxygen in the upper layers, but the deeper layers may have lower levels of oxygen due to decomposition of organic matter. This can result in anaerobic conditions in some parts of the bog, where oxygen levels are very low.
When oxygen levels are high people tend to get a 'high' sensation. When the oxygen levels are low, it feels like you are going to pass out. There are other ways to tell, but generally you would need prodigious equipment, that is most likely very expensive.
When dissolved oxygen levels in a solution become very low, it can lead to hypoxia in aquatic organisms, causing stress, suffocation, and even death. This can disrupt the balance of the ecosystem and result in negative impacts on biodiversity and aquatic life. Monitoring and maintaining proper oxygen levels is crucial for the health of aquatic environments.
Anaerobic bacteria are unable to survive in the presence of oxygen. These bacteria can only grow in environments devoid of oxygen or with very low oxygen levels. Examples of anaerobic bacteria include Clostridium and Bacteroides species.
In the very first shell it has 2 and then it has 6 (in the second shell). =)
The most anaerobic zone in the ocean is found in the waters near the seafloor in regions known as oxygen minimum zones (OMZs). These areas have very low levels of dissolved oxygen, making them suitable habitats for anaerobic organisms. OMZs are often located in deep ocean basins or along coastlines where oxygen supply is limited.

In oceans, Oxygen gets dissolved in a very small proportion from the atmosphere. This process is very gradual. Oxygen also comes from the aquatic plants present in the water bodies.
Evolution is a very slow process, so if the ocean levels rose very fast humans would not evolve fast enough to survive, however they may develop technology to counteract it. It is also very unlikely that the ocean levels will rise that quickly.
The highest oxygen levels on Earth are typically found in remote areas with abundant vegetation and minimal pollution. The lowest oxygen levels can be found in very high altitudes, such as at the summit of Mount Everest, where the air is thin.

Very much because the open ocean is basically the surface-ish area.
When oxygen levels are high people tend to get a 'high' sensation. When the oxygen levels are low, it feels like you are going to pass out. There are other ways to tell, but generally you would need prodigious equipment, that is most likely very expensive.
because you need biological life. You also need liquid water. Mars does have oxygen @ very low levels. Other planets do have oxygen.
The evironment of the ocean is very low-nutrient. This is due to the fact that it is a HUGE environement and none of the ecosystems contained withing (such as coral reefs) can generate enough nutrients to make the entirety of the ocean system contain normal levels of nutrients.
