The photophysiology and primary productivity of phytoplankton within the deep chlorophyll maximum

open access: yes, 2007
In temperate shelf seas, a deep chlorophyll maximum (DCM) persists within the thermocline during summer stratification. This study explores the significance of primary production (PP) within the DCM and provides a detailed investigation into the ...

Stage‐Specific Indicators of Northern Yellowtail Rockfish (Sebastes flavidus) Recruitment in the California Current Ecosystem

open access: yesFisheries Oceanography, Volume 35, Issue 4, Page 630-649, July 2026.
ABSTRACT Oceanographic and ecological conditions can be used to inform forecasts and decision‐making for marine resources, but the dominant drivers of recruitment variability remain poorly understood for many fish stocks. We developed a conceptual life‐history model of the oceanographic and ecological variables that influence the recruitment of ...

Initial Assessment of the Detectability of Cyanotoxin Occurrence Using PACE Satellite Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Microcystin is a major public health hazard during freshwater cyanobacterial blooms, yet its remote detection remains challenging because it lacks any direct optical absorption features. We demonstrate that hyperspectral observations from NASA's PACE Ocean Color Instrument (OCI) can be used to detect elevated microcystin concentrations by ...

Evaluation of climate change scenarios based on aquatic food web modelling

open access: yes, 2008
In the years 2004 and 2005 we collected samples of phytoplankton, zooplankton and macroinvertebrates in an artificial small pond in Budapest. We set up a simulation model predicting the abundance of the cyclopoids, Eudiaptomus zachariasi and Ischnura ...

Training‐Domain Gaps in Data‐Driven Ocean Color Algorithms

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Bio‐optical algorithms serve a critical role, enabling satellite‐based monitoring of the global ocean and its ecosystems. These largely empirical algorithms invert satellite measurements of water leaving reflectance (“ocean color”) to biogeochemical parameters such as chlorophyll a, but often fail to generalize beyond their training data ...

Multidimensional Insights Into the Drivers of Aquatic CO2 Dynamics: A River–Reservoir–Wetland Aquatic Continuum Study Within a Semi‐Arid Region

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Evaluating multiple competing biotic and abiotic processes and how they interact with carbon dioxide (CO2) in aquatic systems, is critical to understanding regional and global carbon cycles. Here, we used an aquatic continuum of the Bahe watershed, within a semi‐arid region, to establish a comprehensive conceptual framework for identifying CO2
