Estimating biogenic silica production of rhizaria in the global ocean
(American Geophysical Union, 2020-03)
Siliceous polycystines and phaeodarians are open-ocean planktonic protists found throughout the water column and characterized by complex siliceous skeletons that are formed, at least partly, through the uptake of silicic ...
Neogene paleoceanography of the eastern equatorial Pacific based on the radiolarian record of IODP drill sites off Costa Rica
(American Geophysical Union, 2017-03)
The Integrated Ocean Drilling Program (IODP) Expedition 344 drilled cores following a transect across the convergent margin off Costa Rica. Two of the five sites (U1381 and U1414) are the subject of the present study. Major ...
Finding of two new radiolarian associations calibrated with ammonoids in the Vaca Muerta Formation (Late Jurassic–Early Cretaceous), Neuquén Basin, Argentina
(Pergamon-Elsevier Science Ltd, 2017-04)
An association of ammonoids and radiolarians retrieved from a sedimentary section of the Vaca Muerta Formation at Vega de Escalone, Neuquén Basin, Argentina, was analized under a strict stratigraphic control. Nine ammonoid ...
Seasonality in the vertical flux and species composition of Radiolaria Polycystina (Protista): Patterns and drivers
(Inter-Research, 2017-08)
Radiolarian flux rates, their intermittency, and changes in their species compositions are assessed using data from 73 time-series sediment trap deployments (1357 samples) covering 7-12 calendar months. Results are analyzed ...
