Dietmar Müller attends Australian open research data showcase in Canberra

by

ANDS Showcase June 2015Today Prof Dietmar Müller attended the Australian open research data showcase in Canberra. The showcase featured a variety of talks and discussions around the benefits and issues concerning open research data. It was an important milestone towards consolidating the Australian effort towards involving Universities and individual researchers in sharing their data.

A highlight was Ian Chubb’s presentation that pointed out that if you look at all papers published in the last 115 years, about 50% were either never cited or only cited once. The hope is that open access publications and associated open research data will improve these sorts of statistics. George Bernard Shaw was quoted by geologist Geoffrey Boulton (Univ. Edinburgh) as pointing out: “If you have an apple and I have an apple and we exchange these apples then you and I will still each have one apple. … Read more…

Long-term interaction between mid-ocean ridges and mantle plumes

Summary
Plate tectonic motions are commonly considered to be driven by slab pull at subduction zones and ridge push at mid-ocean ridges, with motion punctuated by plumes of hot material rising from the lower mantle. Within this model, the geometry and location of mid-ocean ridges are considered to be independent of lower-mantle dynamics, such as deeply sourced plumes that produce voluminous lava eruptions-termed large igneous provinces. Here we use a global plate model to reconstruct the locations of large igneous provinces relative to plumes and mid-ocean ridges at the time they formed. … Read more…

Evaluating global paleoshoreline models for the Cretaceous and Cenozoic

Summary
Paleoshoreline maps represent the distribution of land and sea through geologic time. These compilations provide excellent proxies for evaluating the contributions non-tectonic vertical crustal motions, such as mantle convection-driven dynamic topography, to the flooding histories of continental platforms. Until now, such data have not been available as a globally coherent compilation. Here, we present and evaluate a set of Cretaceous and Cenozoic global shoreline data extracted from two independent published global paleogeographic atlases. … Read more…

Tectonic speed limits from plate kinematic reconstructions

Plate velocities summary figureCitation

Summary
The motion of plates and continents on the planet’s surface are a manifestation of long-term mantle convection and plate tectonics. Present-day plate velocities provide a snapshot of this ongoing process, and have been used to infer controlling factors on the speeds of plates and continents. However, present-day velocities do not capture plate behaviour over geologically representative periods of time. To address this shortcoming, we use a plate tectonic reconstruction approach to extract time-dependent plate velocities and geometries from which root mean square (RMS) velocities are computed, resulting in a median RMS plate speed of ~4 cm/yr over 200 Myr.  … Read more…
