Water mass dynamics drive nitrogen fixation rates and diazotroph community composition in the coastal ocean

open access: yesLimnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Although significant N2 fixation rates (NFRs) have been observed throughout mid‐Atlantic coastal waters, studies have been limited in their temporal coverage, and the methods used to detect nitrogen fixers (diazotrophs) and their findings have varied.

Effect of 4 microalgal diets on the proximal composition, chlorophyll concentration, and total carotenoid content in Artemia franciscana

open access: yesCiencias Marinas, 2023
Microalgae are the primary source of food for Artemia franciscana. In turn, Artemia serve as live food for various species in culture. The chemical composition of Artemia is of great importance because it affects the nutritional quality of the organisms ...

Seasonal and Spatial Variability of Silicon Cycle in Godavari Tidal River Zone

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Dam regulation of tropical monsoonal rivers enhances seasonal contrasts in the tidal river zone (TRZ) hydrology, altering the delivery of dissolved silicon (DSi) to the coastal ocean. Here, we identify the drivers of Si cycling in the Godavari TRZ and quantify their implications for Si delivery to the Bay of Bengal (BoB). We analyzed elemental

Sea Surface Conditions and Antarctic Bottom Water Formation Offshore Cape Darnley, East Antarctica, Over the Last 600 ka: New Insights From the Diatom Record

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract The Cape Darnley marine region of East Antarctica is one of only four sectors where Antarctic Bottom Water (AABW) is produced. AABW formation at Cape Darnley is highly dependent on surface ocean processes—specifically, the high production of frazil ice. Here, we investigated the sea surface conditions at Cape Darnley over the past 600 thousand
