Photosynthesis and net primary productivity in three Antarctic diatoms: Possible significance for their distribution in the Antarctic marine ecosystem [PDF]

, 2011
Photosynthesis and net primary productivity were measured in 3 Antarctic diatoms, Fragilariopsis cylindrus, Pseudo-nitzschia subcurvata and Chaetoceros sp., exposed to rapid changes in temperature and salinity representing a range of conditions found ...

ChloroScan: Recovering Plastid Genome Bins From Metagenomic Data

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Genome‐resolved metagenomics has contributed greatly to discovering prokaryotic genomes. When applied to microscopic eukaryotes (protists), challenges such as the high number of introns and repeat regions found in nuclear genomes have hampered the mining and discovery of novel protistan lineages.

Dissolved Domoic Acid Does Not Improve Growth Rates and Iron Content in Iron-Stressed Pseudo-Nitzschia subcurvata

Frontiers in Marine Science, 2020
Many regions of Antarctica are classified as high nutrient low chlorophyll (HNLC) areas. In these, iron availability is limiting primary productivity and subsequent carbon export.

Density estimation of plankton size spectra: a reanalysis of IronEx II data [PDF]

, 2010
Many critical processes of ecosystem function, including trophic relationships between predators and prey and maximum rates of photosynthesis and growth, are size-dependent.

Hyperspectral optical signatures of iron‐limitation in a coastal upwelling system

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Iron‐limitation within the California Current System drives changes in phytoplankton taxonomic composition and photo‐physiology over a range of spatial scales. Here we demonstrate how these iron‐dependent signatures can be resolved, with high spatial resolution, using continuous ship‐board optical measurements.

Marine Snow Dynamics in the NE Gulf of Mexico: Particle Abundance, Characteristics, and Impacts on Deepwater Horizon Oil Sedimentation

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract The Deepwater Horizon (DWH) oil spill in the NE Gulf of Mexico in 2010 was the largest accidental spill globally. During and after the spill, oil was incorporated into marine snow (marine‐oil‐snow or MOS) and sedimented to the seafloor, accounting for ∼21% of the oil released.

In utero domoic acid toxicity: a fetal basis to adult disease in the California sea lion (Zalophus californianus) [PDF]

, 2008
California sea lions have been a repeated subject of investigation for early life toxicity, which has been documented to occur with increasing frequency from late February through mid-May in association with organochlorine (PCB and DDT) poisoning and ...

On the Role of Western Boundary Currents to Fertilize Adjacent Continental Shelves at Interannual Scales: A Case Study in the Southwestern Atlantic

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Exchanges between continental shelves and open ocean basins regulate the transport of heat, salt, and nutrients. In the Southwestern Atlantic, the western boundary current known as the Malvinas Current (MC) fertilizes the outer shelf through recurrent slope‐water intrusions.
