A New Method for the Detection of Siliceous Microfossils on Sediment Microscope Slides Using Convolutional Neural Networks Open
Diatom communities preserved in sediment samples are valuable indicators for understanding the past and present dynamics of phytoplankton communities, and their response to environmental changes. These studies are traditionally achieved by…

A user‐friendly method to get automated pollen analysis from environmental samples Open
Summary Automated pollen analysis is not yet efficient on environmental samples containing many pollen taxa and debris, which are typical in most pollen‐based studies. Contrary to classification, detection remains overlooked although it is…

Enhanced ocean-atmosphere carbon partitioning via the carbonate counter pump during the last deglacial Open
Several synergistic mechanisms were likely involved in the last deglacial atmospheric p CO 2 rise. Leading hypotheses invoke a release of deep-ocean carbon through enhanced convection in the Southern Ocean (SO) and concomitant decreased ef…
