Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...

DINOFLAGELLATE CYSTS AND CALCAREOUS NANNOFOSSILS FROM THE UPPER CRETACEOUS SARACENO FORMATION (CALABRIA, ITALY): IMPLICATIONS ABOUT THE HISTORY OF THE LIGURIDE COMPLEX

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2003
Organic-walled dinoflagellate cysts and calcareous nannofossils recovered from the turbidites of the Saraceno Formation outcropping in the type area (north-eastern Calabria, Italy) are presented. They provide new information about the age of the Saraceno

Revealing Seasonal Patterns and Metabolism of Microbial Plankton in a Productive Coastal Upwelling System

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Increasing our knowledge about the structure and metabolism of the microbial plankton community in coastal upwelling systems is essential for efficiently managing the resources of these highly productive ecosystems. Here we explore seasonal variations of this community in the NW Iberian coastal upwelling system by measuring variables informing

Age really is an issue [PDF]

open access: yes, 2010
The majority of the source and reservoir rocks for the hydrocarbons in North Sea and the North West Shelf are Jurassic (200–146 Ma) in age. In both the exploration and production phases, the study of palynology, especially fossil dinoflagellate cysts ...

Network Component Analysis Can Identify Potential Axenisation Strategies Circumventing Antibiotic‐Use for Phototrophic Eukaryotic Microalgae

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Network component analysis of published axenisation methods reveals optimal, antibiotic‐free workflows for phototrophic eukaryotic microalgae. Distinct strategies are identified for diatoms, dinoflagellates, and green algae. Verification using microscopy, sequencing, and cell counting enhances reproducibility.

Similarities of the K/Pc dinoflagellate cyst associations between South Atlantic and Indian proto-oceans

open access: yesGeologia USP. Série Científica, 2016
In this contribution we present the composition of the Late Cretaceous / Paleocene dinoflagellate cyst assemblages found in the Pelotas Basin, southern Brazil in order to provide a first paleobiogeographical comparison between this location, India and ...
