Impact of polystyrene microplastics on the growth and photosynthetic efficiency of diatom Chaetoceros neogracile [PDF]

open access: yes
The increasing prevalence of microplastic pollution in aquatic environments has raised concerns about its impact on marine life. Among the different types of microplastics, polystyrene microplastics (PSMPs) are one of the most commonly detected in ...

Holocene neoglacial events in the Bransfield Strait (Antarctica). Palaeocenographic and paleoclimatic significance

open access: yesScientia Marina, 2006
Geochemical analysis, micropalaeontological analysis and radiometric dating techniques were performed on four gravity cores, G-1, G-2, A-3 and A-6, recovered during the BIO Hesperides expeditions GEBRA-93 and FRUELA-96 from the Bransfield Strait

Opportunistic feeding by Antarctic krill in the eastern Weddell Gyre

open access: yesLimnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Antarctic krill, Euphausia superba, is an important species in the Southern Ocean and is vulnerable to climate change. We studied the carbon sources for krill—specifically pelagic and ice‐associated (sympagic) particulate organic matter (POM), representing phytoplankton and sea‐ice algae, respectively—during March 2019 across three distinct ...

An updated view on the long‐term survival and significance of marine protist resting stages

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Resting stages of protists act as biological time capsules when buried in marine sediments, preserving viable cells that enable the study of ecological and evolutionary processes across timescales. Recent studies have extended the known viability in diatoms to several millennia and in dinoflagellates to over a century, while also identifying ...

Regional Variations in Sea Ice and Primary Productivity in the Bering Sea During Marine Isotope Stage 11

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Marine Isotope Stage (MIS) 11 (424–374 ka) has long been an analog for Holocene climate because it is the most recent interglacial period with similar orbital conditions. However, there is global and regional variability in the climate response to MIS 11 warmth.

Modulation of Medium-Chain Fatty Acid Synthesis in Synechococcus sp. PCC 7002 by Replacing FabH with a Chaetoceros ketoacyl-ACP synthase

open access: yesFrontiers in Plant Science, 2016
The isolation or engineering of algal cells synthesizing high levels of medium-chain fatty acids (MCFAs) is attractive to mitigate the high clouding point of longer chain fatty acids in algal based biodiesel.

Quantifying Shifts in the Absorption Budget of the Labrador Sea as the Dominant Phytoplankton Group Changes Between Diatoms and Phaeocystis

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Phytoplankton spring blooms in the Labrador Sea are dominated by diatoms, with Phaeocystis spp. (hereafter Phaeocystis) contributing more than 25% to total phytoplankton biomass. However, in 2015 and 2022, large blooms of Phaeocystis were observed, contributing up to 90% of the surface phytoplankton biomass. In this study, we quantified shifts
