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 ...

Deconstructing co-occurring marine heatwave and phytoplankton bloom events in the Arkona Sea in 2018

open access: yesFrontiers in Marine Science
Between May and August 2018, two separate marine heatwaves (MHWs) occurred in the Arkona Sea in the western Baltic Sea. These heatwaves bookended an extended period of phytoplankton growth in the region.

A novel approach to estimate non‐algal particle absorption for improved retrieval of pigment concentrations in coastal waters

open access: yesLimnology 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 ...

Observations and modelling of the variability of the Solent-Southampton Water estuarine system

open access: yes, 2008
Understanding the effect of physical forcing on estuarine functioning is of major importance to determine the rate of exchange of water, sediments, pollutants and nutrients between the continent and the ocean.

Quantifying Viral Lysis in Microalgae Using Cell‐Free rRNA

open access: yesMicrobiologyOpen, 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 ...

Seasonal Variations in Aerosol Trace Element Source Contributions and Deposition Fluxes to the North Pacific Subtropical Gyre

open access: yesGlobal 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),

VERTICAL DISTRIBUTION PATTERNS OF PHYTOPLANKTON IN SUMMER MICROCYSTIS BLOOM PERIOD OF XIANGXI BAY, THREE GORGES RESERVOIR, CHINA

open access: yes, 2011
Vertical distribution and Diel migration patterns of phytoplankton in Xiangxi Bay, Three Gorges Reservoir of China, were investigated during the summer Microcystis bloom period (July 1, 2-3 and 7, 2008).
