Limnology and Oceanography: Methods, Volume 24, Issue 10, October 2026.Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ), and beam ...

Quantifying Viral Lysis in Microalgae Using Cell‐Free rRNA
MicrobiologyOpen, Volume 15, Issue 5, October 2026.Cell‐free ribosomal RNA (rRNA) dissolved in seawater provides a quantitative proxy for viral lysis in microeukaryotic phytoplankton. Incubation experiments with two distinct host–virus systems revealed marked increases in cell‐free rRNA production per cell, a proxy for lytic mortality, reaching up to 46‐ and 302‐fold relative to noninfected controls ...

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.Abstract Coral reefs are increasingly threatened by local and global stressors. Traditional visual reef monitoring methods are time‐intensive and provide only a snapshot of reef condition. Recent efforts aim to measure reef metabolism, or the balance of net community production (NCP) and net community calcification (NCC), as coral reef carbonate ...

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.Abstract Trace elements deposited in the marine environment affect ocean biogeochemistry in numerous, complex ways. This study quantifies seasonal aerosol trace element (TE) fluxes and evaluates their variability and potential sources over a 2‐year period in the North Pacific subtropical gyre (NPSG). We established the Hawaii Aerosol Time Series (HATS),

On A Novel Estimation Method of Stickiness Parameter of Suspended Particles From Tank Experiments
Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.Abstract Stickiness is a key factor in characterizing coagulation dynamics (aggregation or flocculation). Previous studies have developed methods for estimating constant stickiness parameters. These methods estimate the stickiness parameter based on the reduction rate of the number of particles observed in a simple stirred tank.

Surface Chlorophyll‐a Trends in the Mediterranean Sea: Seasonal Bloom Dynamics and Drivers
Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.Abstract Chlorophyll‐a (Chl‐a) is the most widely used proxy for phytoplankton biomass, bloom intensity, and trophic status in marine ecosystems. We analyzed 27 years (1998–2024) of 1 km‐resolution satellite‐derived Chl‐a data across the Mediterranean Sea and evaluated long‐term trends, bloom phenology, and seasonal variability in relation to sea ...

Seasonal and Spatial Variability of Silicon Cycle in Godavari Tidal River Zone
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.Abstract Dam regulation of tropical monsoonal rivers enhances seasonal contrasts in the tidal river zone (TRZ) hydrology, altering the delivery of dissolved silicon (DSi) to the coastal ocean. Here, we identify the drivers of Si cycling in the Godavari TRZ and quantify their implications for Si delivery to the Bay of Bengal (BoB). We analyzed elemental

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.Abstract The Eastern Mediterranean Sea (EMS) is among the fastest‐warming ocean regions, but the impacts of this warming on phytoplankton are unclear. Here, wintertime field observations were conducted across the EMS. These observations showed that small photosynthetic eukaryotes (<20 μm) dominated phytoplankton communities, collectively accounting for

Amazon River Plume Control on Carbonate Chemistry in the Western Tropical Atlantic
Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.Abstract The Amazon River Plume (ARP) modulates the carbonate system of the western Tropical Atlantic (WTA) through physical and biological processes, including freshwater dilution, biological carbon uptake, and circulation‐driven transport; however, its basin‐scale impact has not been quantitatively assessed.

Microbial Respiration Across Subtropical Eddies: Submesoscale Variability and Biogeochemical Drivers
Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.Abstract Island‐induced eddies from the Canary Islands region propagate southwestward along the Canary Eddy Corridor, exporting biological and biogeochemical properties to the oligotrophic open ocean. However, their contribution to organic matter remineralization, and consequently to the biological carbon pump, throughout their life cycle remains ...
