hapenköyhyysalueita
Hapenköyhyysalueita, known in English as hypoxic areas or oxygen minimum zones (OMZs), are regions within the ocean where dissolved oxygen concentrations are significantly lower than normal. These areas are typically found in enclosed or semi-enclosed seas, or in specific oceanographic settings such as coastal upwelling zones and the mid-depths of the open ocean. The reduction in oxygen is primarily caused by a combination of excessive nutrient input, which fuels algal blooms, and poor water circulation, which prevents oxygen replenishment.
When organic matter, such as dead algae, sinks to the seafloor, it is decomposed by bacteria. This
The consequences of hapenköyhyysalueita are significant for marine ecosystems. Many marine organisms, particularly fish and invertebrates,
