Space Connect reported how EarthByters discovered that Earth’s interactions with Mars can drive deep sea circulation here on Earth. The podcast covers how geological records of the deep sea were used to discover a link between the orbits of the two planets and past global warming patterns, talking through the research and their collaboration with Sorbonne … Read more…
Mars has more influence on Earth than non-astrologers might have thought. Mars is, on average, about 225 million kilometres from Earth, which would suggest that it has little impact on our planet. Which is true, but as they say, a little goes a long way. In our recent paper in Nature Communications, we studied the history of deep … Read more…

12 March 2024, The University of Sydney Media Release Giant whirlpools in warming oceans could mitigate Gulf Stream stagnation Geoscientists at Sydney and Sorbonne have identified a 2.4-million-year cycle in the geological record that show the energy of deep-sea currents wax and wane as oceans cool and warm. Earth’s distance to Mars varies between 55 … Read more…
Astronomical forcing of Earth’s climate is embedded in the rhythms of stratigraphic records, most famously as short-period (10^4–10^5 year) Milankovitch cycles. Astronomical grand cycles with periods of millions of years also modulate climate variability but have been detected in relatively few proxy records. Here, we apply spectral analysis to a dataset of Cenozoic deep-sea hiatuses … Read more…
Join us for a fascinating talk with Guo Dongshan from Zhejiang University. In this EarthByte Seminar Series event, Guo will talk about 1.2-Myr Obliquity Amplitude Modulated the Growth Process of Crusts: Evidence From the Time-Series Analysis of the Crust from CB Seamoun.
Seminar Details:
Earth’s topography and bathymetry with revised boundaries between continental and ocean crust overlain as thin red lines. We have released a refined data set of the boundaries between continental and ocean crust (COBs). The data can be downloaded from zenodo as GPlates-compatible gpmlz and as ESRI shapefile. The COBs are based on the data set … Read more…
Reposted from Earth Logs by Steve Drury The Cryogenian Period that lasted from 860 to 635 million years ago is aptly named, for it encompassed two maybe three episodes of glaciation. Each left a mark on every modern continent and extended from the poles to the Equator. In some way, this series of long, frigid … Read more…
The termination of Neoproterozoic “Snowball Earth” glaciations is marked globally by laterally extensive neritic cap carbonates directly overlying glacial diamictites. The formation of these unique deposits on deglaciation calls for anomalously high CaCO3 saturation. A popular mechanism to account for the source of requisite ocean alkalinity is the shallow-ridge hypothesis, in which initial spreading ridges … Read more…
Join us for a fascinating talk with Dr. Amando Lasabuda from University of Oslo and The University of Sydney. In this EarthByte Seminar Series event, Amando will talk about reconstructing the paleogeography of glaciated continental margins and their sediment source-to-sink systems with an example from the Barents Sea, Norwegian Arctic.
Seminar Details:
The Sturtian ‘Snowball Earth’ glaciation (~717–661 Ma) is regarded as the most extreme interval of icehouse climate in Earth’s history. The exact trigger and sustention mechanisms for this long-lived global glaciation remain obscure. The most widely debated causes are silicate weathering of the ~718 Ma Franklin LIP, and changes in the length and degassing of … Read more…
Join us for an insightful seminar with Antoniette from University of Glasgow. In this EarthByte Seminar Series event, Antoniette will talk about the evolution of slab morphology and topography at subduction zones. Her work can contribute to a better understanding of subduction processes from deep slab dynamics to continental deformation, the evolution of topography at subduction zones, and basin formation and continental extension.
Seminar Details:
Since the Mesozoic, eastern NE Asia has experienced multiple tectonic events, resulting in a complex structure and forming one of the world’s largest Meso-Cenozoic lacustrine basin systems. Presently, basin evolution models require further elucidation regarding the simultaneous generation of diverse rift basins and the potential impact stemming from the closure of the Mudanjiang Ocean, whose … Read more…
Join us for an insightful seminar with Hojat Shirmard from the EarthByte Group. In this EarthByte Seminar Series event, Hojat will delve into the discovery of a new deep-seated world-class porphyry copper deposit named Sereydoun, which resulted from a distinctive approach to processing, analyzing, and interpreting airborne geophysical data and satellite images in the cluster of Sarcheshmeh copper porphyry mine.
