The Toarcian Oceanic Anoxic Event (T-OAE) interval was cored at Colle di Sogno and Gajum in the Lombardy Basin (Southern Alps, northern Italy). The Sogno and Gajum cores recovered 26.83 and 31.18 stratigraphic metres, respectively, of pelagic sedimen

Mid-Cretaceous paleoenvironmental changes in the western Tethys

Autor: C. Bottini, E. Erba

Publikováno v: Climate of the Past, Vol 14, Pp 1147-1163 (2018)

We present a continuous record of surface water temperature and fertility variations through the latest Barremian–Cenomanian interval (ca. 27 Myr) based on calcareous nannofossil abundances from the western Tethys. The nannofossil temperature

Impact of trace metal concentrations on coccolithophore growth and morphology: laboratory simulations of Cretaceous stress

Autor: G. Faucher, L. Hoffmann, L. T. Bach, C. Bottini, E. Erba, U. Riebesell

Publikováno v: Biogeosciences, Vol 14, Pp 3603-3613 (2017)

The Cretaceous ocean witnessed intervals of profound perturbations such as volcanic input of large amounts of CO2, anoxia, eutrophication and introduction of biologically relevant metals. Some of these extreme events were characterized by size red

A REVISED METHOD FOR OBSERVING THE SAME NANNOFOSSIL SPECIMENS WITH SCANNING ELECTRON MICROSCOPE AND LIGHT MICROSCOPE

Autor: C. PIRINI RADRIZZANI, D. CASTRADORI, E. ERBA, G. GUASTI, A. RIZZI

Publikováno v: Rivista Italiana di Paleontologia e Stratigrafia, Vol 95, Iss 4 (2018)

A new method for the observation of the same nannofossil specimens with scanning electron microscope and light microscope, involving the use of a grid, is described. This technique provides a complete analysis of the morphological diagnostic characte

Climate variability and ocean fertility during the Aptian Stage

Autor: C. Bottini, E. Erba, D. Tiraboschi, H. C. Jenkyns, S. Schouten, J. S. Sinninghe Damsté

Publikováno v: Climate of the Past, Vol 11, Iss 3, Pp 383-402 (2015)

Several studies have been conducted to reconstruct temperature variations across the Aptian Stage, particularly during early Aptian Oceanic Anoxic Event (OAE) 1a. There is a general consensus that a major warming characterized OAE 1a, although some s
