Coral carbonate pH records show localized stability within Philippine waters

Carolina Galdino — Mon, 20 Jul 2026 12:00:00 +0000

The process of decreasing seawater pH due to increasing atmospheric carbon dioxide known as ocean acidification is a global phenomenon with very strong regional effects. We report the first seasonal and interannual carbonate chemistry variabilities in the Philippines determined using carbonate boron systematics. Coral δ11B-pHsw from two contrasting site conditions showed more positive trends than basin-wide […]

Share the knowledge on the ocean The ocean is the foundation of life on Earth. But its health is at grave risk as ecosystems and habitats approach or surpass critical tipping points. In the search for solutions, ocean science is indispensable. The third World Ocean Assessment offers the most comprehensive evaluation to date, providing Governments, institutions and the public […]

Ocean acidification may be shrinking the brains of the world’s most intelligent invertebrates

Carolina Galdino — Mon, 20 Jul 2026 11:57:00 +0000

An ongoing research project exploring the effects of rising levels of oceanic CO2 on squid neurology reveals that exposure to future levels of ocean acidification could shrink their brain volume by around 50%. This severe brain shrinkage appears to be most pronounced in the areas that interpret visual information, correlating with significant reductions in normal feeding […]

The effects of decreased pH and increased temperature on survival and shell development of the larvae of the endemic Hawaiian oyster Dendostrea sandvichensis

Carolina Galdino — Fri, 17 Jul 2026 12:00:00 +0000

Climate change models predict future ocean-wide decreases in pH and increases in temperature, posing a serious threat to calcifying marine invertebrates. In Hawaiʻi, local seawater temperature and pH are predicted to change even more rapidly. The Hawaiian oyster Dendostrea sandvichensis, an endemic species, remains understudied despite its ecological roles in reef- building, biofiltration, and as […]

Impacts of ocean acidification on reproduction and early life development in marine teleost fish—a synthesis

Carolina Galdino — Fri, 17 Jul 2026 11:59:00 +0000

Ocean acidification (OA) remains a major and underexplored threat to marine fishes, particularly regarding reproductive physiology and early life stages (ELS). Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist. Most studies focussed on a limited set of species from North America and Europe, leaving broad uncertainty across phylogenetic […]

Distinct polar carbon regimes reveal hemispheric asymmetry in surface ocean pCO₂ regulation

Carolina Galdino — Fri, 17 Jul 2026 11:58:00 +0000

Polar oceans play a major role in the global carbon cycle, absorbing a substantial fraction of human-emitted carbon dioxide and helping regulate Earth’s climate. Extreme conditions and seasonal sea-ice limit in situ observations, leaving major uncertainties in how carbon exchange varies across these regions. Consequently, the processes controlling surface ocean carbon at high latitudes remain […]
