RE: https://mstdn.social/@compoundchem/116716533544196361
The #climatecrisis has multiple negative effects on the maritime #biosphere.
The rise in temperature in the sea gets most attention, but #oceanacidification is a major risk as well to the #maritime #ecology - threatening the stability of the #foodchain in the world's #oceans.
Within this century the skeletons of maritime organisms, such as #corals, will be at risk to erode faster then they can be sustained. This will also affect #plankton which forms the basis of the maritime #food chain.

Our history provides a terrifyingly accurate mirror for this exact scenario: the Paleocene-Eocene Thermal Maximum (PETM) 56 million years ago. During this ancient spike, a massive injection of carbon triggered rapid global warming, severe ocean acidification, and altered ocean circulation. The PETM shows us exactly what happens to the planet's equilibrium when climate systems are pushed past their tipping points. -

This initial warming likely triggered positive feedback loops, such as the release of methane from thawing permafrost or submarine "fire ice" (gas hydrates), which further accelerated the heating.The consequences for the environment were dire:
• Ocean Acidification: The oceans absorbed a massive amount of carbon, making them highly acidic and dissolving the calcium carbonate skeletons of many marine species.

Structural Decay: Reef Fish Sociality Wanes as Ocean Acidity Rises
Ocean acidification is breaking down reef habitats, forcing fish into smaller groups and making them less safe. Learn how this affects fish safety and food.

Reef fish are now forming smaller groups than before because the ocean is becoming more acidic. This is like having fewer people watching out for danger.

Just increasing popular awareness of #oceanacidification seems very worthwhile.
One question from someone too lazy to research the chemistry: is the proportion of H+ ions increasing slower than the proportion of CO₂ in the atmosphere, and if so why? (Presumably surface water concentrations are increasing, but is something like chloride or sulphate buffering it?)

Got pesky, #invasive #corals? Blast ‘em away with air guns
While corals around the world are dying in vast numbers due to #oceanacidification, #climatechange, #overfishing and disease, invasive counterparts such as #suncorals are taking over biodiversity hotspots. Blasts of compressed air can probably rid ecosystems of these rapidly spreading intruders and prevent them from reestablishing.

#PlasticPatrol: the #CitizenScientists tackling #litter in #Australian #waterways
#Plastics make up the majority of litter across the country. In the absence of regulation, the public are taking matters into their own hands
by James Norman, Fri 30 Jan 2026
"Neil Blake weighs a paper bag of fake grass fragments he has collected from a stormwater gutter near #DarebinCreek in #Melbourne’s north.
"Over the past three years Blake has conducted 56 collections of synthetic turf in the waterway alongside the KP Hardiman Reserve hockey pitch.
" 'I noticed that a local hockey pitch was being replaced and the plastic surface was running off into the local environment,' he says. Strong northerly winds and #LeafBlowers had helped shed the turf fragments into the local #environment.
"In addition to impacts on #AquaticEcosystems, scientific analysis suggests #PlasticPollution is exacerbating #ClimateChange, #biodiversity loss and #OceanAcidification.
"Australians produce more than 3m tonnes of plastic waste each year, and according to Clean Up’s annual survey of parks, beaches, creeks and other public spaces, plastics make up more than 80% of litter across the country. A review by the New South Wales chief scientist found that one #SyntheticTurf field could transport between 10kg and 100kg of plastic fragments into the #stormwater system or local waterways.
"Blake has taken advantage of the electronic scales provided by the newly opened community science laboratory in the Port Phillip #EcoCentre in #StKilda, to quantify his samples to present to the local council and the Environment Protection Authority. The lab hosts facilities including microscopes, measuring equipment, safety gear and access to advice from trained scientists.
"It’s one example of citizen scientists tackling the growing problem of plastics in #waterways, including #beaches, #rivers and dive sites around the country."

We often discuss the threat of #OceanAcidification (and #Climate Change ) on shallow reefs, but it does not spare deep reefs. As the #ocean acidifies, the aragonite saturation horizon shallows, and with it the zone many #reef builders can inhabit.
