Lateral Coastal Blue Carbon Export Fuels a Deep‐Ocean Carbon Sink in an Oligotrophic Warm Pool

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 7, July 2026.
Abstract Coastal blue carbon (CBC) ecosystems export organic matter offshore, but their contribution to deep‐ocean carbon sequestration remains insufficiently quantified. We measured depth‐resolved particulate organic carbon (POC) fluxes, δ13C signatures, and environmental DNA (eDNA) from sediment traps deployed at 150, 500, and 1,000 m in the western ...

Data_Sheet_1_Differential Activity of Coexisting Prochlorococcus Ecotypes.PDF

open access: yes, 2019
The abundance and widespread distribution of the unicellular cyanobacterium Prochlorococcus is attributed to its extensive genetic diversity. At least twelve distinct clades, or ecotypes, of Prochlorococcus have been discovered so far, and follow ...

Phytoplankton transcriptomic and physiological responses to fixed nitrogen in the California current system.

open access: yesPLoS ONE, 2020
Marine phytoplankton are responsible for approximately half of photosynthesis on Earth. However, their ability to drive ocean productivity depends on critical nutrients, especially bioavailable nitrogen (N) which is scarce over vast areas of the ocean ...

Increase in Summer–Fall Chlorophyll Blooms in the Northeastern Pacific Subtropical Gyre Over the Past Three Decades

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Large chlorophyll blooms spanning hundreds of square kilometers and persisting for weeks‐months, have been repeatedly observed in satellite records of ocean color in the North Pacific Subtropical Gyre (NPSG). These blooms, typically defined as chlorophyll concentrations exceeding some threshold (generally ∼0.15 mg m−3), occur uniquely within ...

Ecological studies on Prochlorococcus in China seas [PDF]

open access: yes, 2002
Prochlorococcus, a tiny oxygenic photosynthetic picoplankton with unique pigment composition, has been found to be ubiquitous and abundant in the world oceans, and has been recognized to be closely related to living resources and environmental issues. It

Temporal transcriptional patterns of cyanophage genes suggest synchronized infection of cyanobacteria in the oceans

open access: yesMicrobiome, 2020
Background Based on the peak expression times during infection, early, middle, and late genes have been characterized in viruses (cyanophages) that infect the unicellular cyanobacterium Prochlorococcus.

Photosynthetic primary production in the Mesoproterozoic

open access: yesNew Phytologist, Volume 251, Issue 1, Page 64-80, July 2026.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Exploring Global Patterns of Trace Metal Limitation as a Regulator of the Distribution of Dominant Marine Phytoplankton Groups

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
By synthesizing decades of culture data with modern oceanographic datasets, we modelled trace metal limitation of phytoplankton. Our analysis reaffirms the critical role of iron but additionally highlights a significant, growing impact of zinc on the biological pump in future oceans.
