Phytoplankton Dynamics and Environmental Variability in the Eastern Equatorial Pacific Over Glacial‐Interglacial Timescales

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 4, April 2025.
Abstract The Eastern Equatorial Pacific serves as a critical region for understanding the interplay between phytoplankton dynamics and global carbon cycling over glacial‐interglacial timescales. This study investigates the calcareous nannofossils from sediment core MV1014‐02‐17JC (17JC) and previously published diatom assemblage data from core MD02 ...

Nannoplankton and the Metals

open access: yes, 1972
Intertwined with the other pollution difficulties of the Coeur d'Alene and Spokane region is the problem of the metals and the nannoplankton. Metals, such as cadmium, lead, copper, and zinc, are coming down the South Fork to the main stem of the Coeur d ...

ENVIRONMENTAL CONTROL OF NANNOPLANKTON AND FORAMINIFERA ASSEMBLAGES IN MADURA WATERS

open access: yes, 2016
Nannoplankton is widely used for determining age of sediments following the other microorganism foraminifera since the late 1960s; and it was started being used for marine geography study in the year of 1984.

Calcareous nannofossil paleofluxes as proxy of pCO2 fluctuations during the Early Cretaceous

open access: yes, 2010
Calcareous nannoplankton is an excellent proxy for detecting present and paste surface water conditions, being extremely sensitive to changes in temperature, fertility, salinity and chemical conditions of the oceans.
