Ecological Constraints of Plankton Bio-Indicators for Water Column Stratification and Productivity: A Case Study of the Holocene North Aegean Sedimentary Record

Journal of Marine Science and Engineering, 2021
This study presents novel findings on the drivers of the calcitic planktonic foraminiferal and aragonitic pteropod Holocene assemblages of the North Aegean Trough (northeastern Mediterranean), an area recording the interaction between dynamic water ...

Key Environmental Factors Controlling Planktonic Foraminiferal and Pteropod Community’s Response to Late Quaternary Hydroclimate Changes in the South Aegean Sea (Eastern Mediterranean)

Journal of Marine Science and Engineering, 2020
A multidisciplinary study was conducted in order to investigate the environmental factors affecting the planktonic foraminiferal and pteropod communities of the south Aegean Sea. Aspects of the Late Quaternary paleoceanographic evolution were revealed by

Mineralogical and morphometric aspects of the rock analysis as the basis for choosing a scheme for ore preparation [PDF]

E3S Web of Conferences, 2020
The complexity of deep processing of fine-grained and refractory mineral raw materials is determined by the difficulty of disclosing aggregates of ore components during disintegration and extracting them into commercial products of standard quality.

Original meaning of the notion and term “formation” in geology [PDF]

Geološki Anali Balkanskoga Poluostrva, 2014
The notion of (geological) formation has gradually developed through mostly German terms: from ein Gebirge, which was used by Saxon miners for several centuries (AGRICOLA), then Schichten, Bergart (LEHMANN) and serie montana (FUCHSEL) to ...

Insights into the Paleostress Analysis of Heterogeneous Fault-Slip Data by Comparing Different Methodologies: The Case of the Voltri Massif in the Ligurian Alps (NW Italy)

Applied Sciences, 2022
One of the most critical stages in fault-slip data stress analysis is separating the fault data into homogeneous subsets and selecting a suitable analysis method for each subset.

Quantitative data on latest-quaternary benthic foraminiferal assemblages in the South Evoikos Gulf semi-enclosed basin (central Aegean, Greece)

Data in Brief, 2019
We herein present an original high-resolution dataset on the Late Pleistocene to Holocene (>15.17 ka BP) benthic foraminiferal record of two continuous sediment cores (DEH 5 and DEH 1), drilled from the shallow (max.

An Improved Cleaning Protocol for Foraminiferal Calcite from Unconsolidated Core Sediments: HyPerCal—A New Practice for Micropaleontological and Paleoclimatic Proxies

Journal of Marine Science and Engineering, 2020
Paleoclimatic and paleoceanographic studies routinely rely on the usage of foraminiferal calcite through faunal, morphometric and physico-chemical proxies.
