Advancing Water Security in the Tropical and Subtropical Regions: An Integrative Topic Modeling Approach

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Orbital Variability in Grazing Proportion: New Insights From Sedimentary Amino Acid δ15N Records of the Western Equatorial Pacific

open access: yesAGU Advances, Volume 7, Issue 1, February 2026.
Abstract The carbon sequestration capacity of the biological carbon pump (BCP) is determined by surface ocean carbon fixation and the transportation of fixed carbon to the ocean interior, which is closely linked to the trophic structure of planktonic ecosystem.

Seasonality in Marine Organic Carbon Export and Sequestration Pathways

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The ocean's biological carbon pump transports organic carbon from the surface to depth via three main pathways: the gravitational sinking of particles, active transport by vertically migrating zooplankton, and mixing and advection of suspended and dissolved organic carbon.

Pliocene–Pleistocene Redox Evolution of the Peruvian Margin: A Multi‐Proxy Approach

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract Due to upwelling of nutrient‐rich waters, the Peruvian Margin is one of the most productive regions of the global ocean, hosting one of the most pronounced and shallowest oxygen minimum zones. This combination of high productivity and low oxygen makes the Peruvian margin a critical site for reconstructing past environmental changes.

Diversity, Function and Activity of DNA Viruses in the Qiangyong Proglacial Lake Sediment, the Tibetan Plateau

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This study identified DNA viruses from Qiangyong proglacial lake sediments on the Tibetan Plateau, revealing a highly diverse and previously uncharacterized viral community. These viruses influence microbial community structure and function by infecting key nutrient‐transforming taxa and encoding auxiliary metabolic genes that modulate host metabolism.
