Ocean Alkalinity Enhancement in Deep Water Formation Regions Under Low and High Emission Pathways

Earth's Future
Ocean Alkalinity Enhancement (OAE) is an ocean‐based Carbon Dioxide Removal (CDR) method to mitigate climate change. Studies to characterize regional differences in OAE efficiencies and biogeochemical effects are still sparse.

A novel methodology to characterize the potential impacts of electrochemical ocean alkalinity enhancement on juvenile coho salmon (Oncorhynchus kisutch)

Frontiers in Climate
Ocean alkalinity enhancement (OAE) includes a branch of marine carbon dioxide removal (mCDR) methods that add alkalinity to the surface ocean, leveraging the ocean's vast natural ability to capture and store atmospheric CO2.

Stability of alkalinity in the land-ocean transition zone: a geochemical CDR perspective for the Elbe River, Germany

Environmental Research Letters
Carbon dioxide removal (CDR) strategies like enhanced weathering and river/ocean alkalinity enhancement have been suggested to increase alkalinity in rivers, coastal areas, and eventually oceans.

Slaking quicklime with seawater for open-ocean alkalinity enhancement: technical feasibility and cost implications

Frontiers in Climate
Scalable carbon dioxide removal (CDR) solutions, such as ocean alkalinity enhancement (OAE), are necessary to mitigate climate change. One OAE approach is open-ocean liming, consisting in distributing hydrated lime (Ca(OH)2) to increase seawater ...

Interactions between ocean alkalinity enhancement and phytoplankton in an Earth system model

Biogeosciences
Abstract. The functioning and efficiency of ocean alkalinity enhancement (OAE) as a CO2 removal strategy is well investigated in model studies, but risks for the ecosystem are presently not considered in models. Our study examines OAE–phytoplankton feedbacks in an Earth system model by adding carbonate system dependencies to the phytoplankton growth ...

Entering the Era of Directly Supporting Society With Observation‐Based Ocean Acidification Data

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Ocean acidification is a growing concern for many nations around the world. However, our capacity to monitor changes in carbonate chemistry with sufficient spatial and temporal resolution, has until now, been limited, which has impeded effective action and decision‐making at international, national, and regional levels.

Microplastics and nanoplastics in water: Improving removal in wastewater treatment plants with alternative coagulants

The Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3744-3757, July 2026.
The contaminant removal performance of a conventional coagulant, alum, and alternative coagulants, aluminium chlorohydrate (ACH) and ACH + pDADMC, are compared in challenging wastewater treatment conditions (pH >7.8). The interactions of each coagulant with a negatively charged surface are depicted based on quartz crystal microbalance with dissipation ...

Ultra‐High Strength and Environmentally Stable Fluorinated Solid‐State Ion‐Conductive Elastomers with Folding‐Paper‐Structured Triboelectric Nanogenerators for Wave Energy Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
In this work, a polyurethane‐based fluorinated SICEs with excellent mechanical properties (7.35 MPa and 61.4 MJ m−3), conductivity (4.2 × 10−4 S cm−1), and harsh environmental resistance were prepared by a “three birds with one stone” strategy that combines multiple interactions with fluorine effects. The paper‐folding TENG is capable of harvesting not

Harnessing nature's buffer: Assessing the role of bivalve shells in coastal alkalinity regeneration

Limnology and Oceanography Letters
Bivalve shells, a natural alkaline material, play a crucial role in coastal carbon cycles by influencing total alkalinity (TA) and dissolved inorganic carbon (DIC). This study investigated oyster shell dissolution in Narragansett Bay, Rhode Island, under
