Acid rain has a much less harmful effect on oceans on a global scale, but it creates an amplified impact in the shallower waters of coastal waters. [92] Acid rain can cause the ocean's pH to fall, known as ocean acidification, making it more difficult for different coastal species to create their exoskeletons that they need
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

Laze plumes forming from pāhoehoe lava flowing into the Pacific Ocean, Hawaii. Laze is acid rain and air pollution arising from steam explosions and large plume clouds containing extremely acidic condensate (mainly hydrochloric acid), which occur when molten lava flows enter cold oceans. [1] [2] The term laze is a portmanteau of lava and haze.
The absorption of CO 2 from the atmosphere does not affect the ocean's alkalinity. [34]: 2252 This is important to know in this context as alkalinity is the capacity of water to resist acidification. [35] Ocean alkalinity enhancement has been proposed as one option to add alkalinity to the ocean and therefore buffer against pH changes.
One of the changes is in the acidity levels of the ocean, which have been consistently increasing at twice the rate of the Pacific and Atlantic oceans. [2] Arctic Ocean acidification is a result of feedback from climate system mechanisms, and is having negative impacts on Arctic Ocean ecosystems and the organisms that live within them.
Increased ocean stratification reduces the introduction of nutrients from the deep ocean into the euphotic zone resulting in decreases in both net primary production and sinking particulate matter. [3] Additional research suggests shifts in the geographical range of many species could also occur with warming, with many of them shifting poleward ...

Organisms can become stressed due to ocean acidification and the disappearance of healthy coral reefs, such as the Great Barrier Reef, is a loss of habitat for several taxa. Ocean acidification makes it harder for organisms to reproduce affecting the ecosystem in the Great Barrier Reef.
