The effects of single and multiple climate-driven stressors exposures on the seagrass Posidonia oceanica: phenological, cellular, and genetic adaptations

Carolina Galdino — Fri, 10 Jul 2026 12:00:00 +0000

Posidonia oceanica is a foundation seagrass species endemic to the Mediterranean Sea, where it forms highly productive meadows that support biodiversity, coastal protection and long-term blue carbon storage. However, these ecosystems are increasingly threatened by the combined effects of climate change and local anthropogenic pressures, including ocean warming, marine heatwaves, ocean acidification, hypersalinity and thermal […]

Global governance failing to address growing threat of ocean acidification to food security, new study warns

Carolina Galdino — Fri, 10 Jul 2026 11:58:00 +0000

International institutions managing fisheries and climate change operate in silos, leaving a critical gap in protection for communities dependent on blue foods. London, 18th June 2026 – A new study, launched during Our Oceans Conference being held in Mombasa, finds that international governance frameworks are poorly equipped to address the combined threat of ocean acidification (OA) and […]

Impact of climate change on Portuguese marine coastal environments

Carolina Galdino — Thu, 09 Jul 2026 12:00:00 +0000

The potential impacts of climate change on marine habitats were assessed using RCP4.5 and RCP8.5 projections of environmental parameters that included sea surface temperature (SST), pH, salinity, planktonic productivity (PP) and current strength (CS). The analysis was conducted separately for three distinct oceanographic regions of the Portuguese coastline (North, Centre and South) up to the […]

Climate assessment report for the Central Arctic Ocean (CAO) [Suppl. to ICES Scientific Reports 8(25)]

Carolina Galdino — Thu, 09 Jul 2026 11:59:00 +0000

Climate change is transforming the Central Arctic Ocean (CAO) at an unprecedented pace. Sea ice is rapidly declining in extent, thickness, and age, with projections indicating an ice-free summer Arctic by mid-century, possibly earlier. This loss of ice amplifies warming, alters stratification and circulation, and accelerates ocean acidification—occurring up to four times faster than the […]

Measuring carbon dioxide uptake at PAP-SO

Carolina Galdino — Thu, 09 Jul 2026 11:58:00 +0000

Globally the ocean absorbs about a quarter of the carbon dioxide produced on land. This varies seasonally and by region. We visit the PAP-SO in spring just as the largest plankton bloom is starting, shown by the orange and red colours in the satellite map below. This productivity makes the northeast Atlantic a key region […]

Acidification dominates over hypoxia in controlling estuarine nitrogen removal Dynamics under coupled stressors

Carolina Galdino — Wed, 08 Jul 2026 12:00:00 +0000

As critical transitional zones between land and sea, estuaries are confronting the dual threats of increasing acidification and hypoxia driven by human activities and climate change. However, the combined effects of these stressors on estuarine nitrogen removal processes remain poorly understood. In this study, using stable-isotope tracing and molecular techniques in the Yangtze estuary, we […]

The fate of macroalgal carbon under microbial anaerobic respiration: a critical factor in macroalgae cultivation for climate change mitigation

Carolina Galdino — Wed, 08 Jul 2026 11:59:00 +0000

Highlights Abstract Macroalgae play a significant role in global carbon sequestration. Substantial macroalgal organic carbon inputs and subsequent degradation can cause deoxygenation; however, the impact of oxygen deficiency on carbon fate remains understudied, which is critical for assessing the climate mitigation role of macroalgae. Here, we investigated changes in the carbon pool and non-CO2 greenhouse gases […]
