Bacterial Control of Metabolic Balance in the Sargasso Sea Near Bermuda: Insights From Data‐Assimilative Biogeochemical Modeling

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Heterotrophic marine bacteria are key players in the ocean carbon cycle. However, their exact contributions to net community production (NCP)—a crucial metric for the biological pump that indicates the metabolic balance and sets the upper limit for carbon export—remain unquantified due to limited bacterial integration in ocean biogeochemical ...

Eutrophication and the management of planktonic algae: What Vollenweider couldn't tell us [PDF]

open access: yes, 1992
The ”Vollenweider model” is a sophisticated mathematical statement about the long-range behaviour of (mainly temperate) lakes and their ability to support phytoplankton chlorophyll.

Highly Resolved Surface Phytoplankton Community Composition Along the British Columbia Coast, Derived From In Situ Hyperspectral Radiometry

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Quantitative measurements of phytoplankton community composition (PCC) are essential for understanding fisheries production, ocean nutrient cycling, and the export of particulate carbon to the ocean interior. However, these measurements are constrained in dynamic coastal waters due to the spatial‐temporal constraints of in situ sampling ...

Production of Oxygen‐ and Sulfur‐Containing Volatile Organic Compounds by Marine Bacteria From Coastal Seawater

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Previous studies primarily examined volatile organic compound (VOC) production and consumption in isolated cultures or bulk seawater. In contrast, this study focused on natural bacterial assemblages, excluding phytoplankton, to elucidate bacterial contributions to VOC cycling in marine ecosystems. Marine bacteria have traditionally been viewed

Unraveling the Influence of Short‐Lived, Three‐Dimensional, Eddy‐Like, Coherent, Oceanic Structures on Phytoplankton Dynamics and Nutrient Transport

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Three‐dimensional eddy‐like coherent structures—enclosed water bodies with limited exchange with their surroundings—play a significant role in transport processes and the regulation of phytoplankton blooms. Here, we extend traditional two‐dimensional analyses by examining the full three‐dimensional dynamics of temperature, nutrient ...
