The downward legacy of a phytoplankton bloom in the oligotrophic North Pacific Subtropical Gyre

open access: yesLimnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Ocean particles are a heterogeneous collection, including living and dead cells, feces, mucus‐rich aggregates, and mineral shells and frustules. In the well‐lit upper ocean, phototrophic processes fuel production of particulate matter; however, only a relatively small percentage (< 10% per day) of this material (mostly detrital) escapes the ...

From net sink to episodic source: Seasonal dissolved inorganic carbon budget in an intertidal basin

open access: yesLimnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract The back‐barrier basin of Spiekeroog in the East Frisian Wadden Sea is a biogeochemically dynamic intertidal system that plays a key role in regulating coastal carbon fluxes and regional dissolved inorganic carbon (DIC) budgets. Compared to total alkalinity, DIC fluxes in this region remain poorly quantified, limiting a comprehensive ...

Effects of Sediment‐Control Operations on Fish and Macroinvertebrate Communities in Dam Reservoirs

open access: yesRiver Research and Applications, Volume 42, Issue 8, Page 1781-1798, October 2026.
ABSTRACT Sediments are avoided in many river and dam managements because of their adverse effects on water usage and flood control. Recently, sedimentation control measures, including sluicing, have been employed to manage sediments in river channels and restore communities in dammed rivers.

Metabolic Dynamics of an Offshore Coral Reef in the Central Red Sea: Observations From Autonomous Sensors

open access: yesGlobal 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 ...

Surface Chlorophyll‐a Trends in the Mediterranean Sea: Seasonal Bloom Dynamics and Drivers

open access: yesJournal 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 ...
