The EU project ASTARTE aims at developing a higher level of tsunami hazard assessment in the North East Atlantic, Mediterranean and Connected seas (NEAM) region by a combination of field work, experimental work, numerical modeling and technical development. The project is a cooperative work of 26 institutes from 16 countries and links together the description of past tsunamigenic events, the identification and characterization of tsunami sources, the assessment of the impact of such events, and...
Departing from an ideal: An asymmetric, bimodal and non-Equatorial latitudinal gradient of marine diversity in Western Atlantic burrowing shrimps (Decapoda: Axiidea and Gebiidea)Patricio Hernáez, Phillip Fenberg & Marcelo Rivadeneira
Aim: Despite the generality of the latitudinal gradient of species diversity (LDG) phenomenon, there is growing evidence showing deviations from an idealized pattern, i.e., a single peak of species richness symmetrically centered in the Equator, but the underlying causes remains little studied. We here evaluate the existence of departures from the idealized LDG in a group of marine crustaceans and the explanatory role of environmental variables. Location: Coastal shelf (< 200 m depth) along the...
High-resolution LA-MC-ICP-MS Pb isotope data (65.5 - 63 Ma) for Tropic Seamount, north-east Atlantic, and Matlab and R processing scripts for cyclostratigraphic analysisPierre Josso, Tim van Peer, Matthew Horstwood, Paul Lusty & Bramley Murton
The excel table presents the high-resolution LA-MC-ICP-MS Pb isotope data (± 2S%) produced for the Paleocene interval of Fe-Mn crust core sample 085_004 recovered in 2016 during the JC142 expedition to Tropic Seamount for the MarineE-Tech project. A detailed description of the sample can be found in Josso et al., 2019 and 2020. The Scripts data are Matlab and R readable file presenting all scripts and built-in functions used during the processing of the data...
While microplastics are known to pervade the global seafloor, the processes that control their dispersal and concentration in the deep sea remain largely unknown. Here we show that thermohaline-driven currents, which build extensive seafloor sediment accumulations, can control the distribution of microplastics and create hotspots of up to 1.9 million pieces m^2. This is the highest reported value for any seafloor setting, globally. Previous studies propose that microplastics are transported to the seafloor by vertical...
The file contains the LA-MC-ICP-MS composite Pb isotope ratios for Tropic Seamount, north-east Atlantic Ocean, spanning a deposition history covering the last 75 Ma. The record was obtained by analysis of hydrogenetic ferromanganese crust samples recovered during the 2016 JC142 expedition of the MarineE-Tech project.
Here we present the dataset collected during a CO2 flow-through test using a synthetic sandstone of high porosity and permeability, originally saturated with high salinity brine, performed under realistic shallow reservoir conditions stress. During the test, we collect geophysical data (elastic and electrical properties) which record petrophysical variations in the rock related to the precipitation of salt, induced by a continuous CO2 flow through the sample.
The file contains the validation data on certified reference material for Nd isotope measurement, the LA-MC-ICP-MS composite Pb isotope ratios and Nd isotope time series for Tropic Seamount, north-east Atlantic Ocean. The dataset spans a deposition history covering the last 75 Ma. The record was obtained by analysis of hydrogenetic ferromanganese crust samples recovered during the 2016 JC142 expedition of the MarineE-Tech project.
