Exploring coral reef responses to millennial-scale climatic forcings: insights from the 1-D numerical tool pyReef-Core v1.0

In a paper published this week in European Geosciences Union – EGUGMD Journal, Tristan Salles, Jodie Rae, Jody M Webster & Belinda Dechnik present a 1-D model of coral reefs’ evolution over centennial to millennial timescales. The model allows to estimate the effects of environmental conditions (such as oceanic variability, sedimentation rate, sea-level fluctuations or tectonics) and ecological coral competition on reef … Read more…

The influence of carbonate platform interactions with subduction zone volcanism on palaeo-atmospheric CO2 since the Devonian

Abstract: The CO2 liberated along subduction zones through intrusive/extrusive magmatic activity and the resulting active and diffuse outgassing influences global atmospheric CO2. However, when melts derived from subduction zones intersect buried carbonate platforms, decarbonation reactions may cause the contribution to atmospheric CO2 to be far greater than segments of the active margin that lacks buried carbon-rich rocks and … Read more…

Exploring coral reef responses to millennial-scale climatic forcings: insights from the 1-D numerical tool pyReef-Core v1.0

Abstract: Assemblages of corals characterise specific reef biozones and the environmental conditions that change spatially across a reef and with depth. Drill cores through fossil reefs record the time and depth distribution of assemblages, which captures a partial history of the vertical growth response of reefs to changing palaeoenvironmental conditions. The effects of environmental factors on … Read more…

Workshop on “Bayeslands: Bayesian inference for Badlands”

Overview: In recent years, the Bayesian inference has become a popular methodology for the estimation and uncertainty quantification of parameters in geological and geophysical forward models via the posterior distribution. Badlands is a basin and landscape evolution model for simulating topography development at various space and time scales. This workshop will present  BayesLands which provides … Read more…

Untangling The Role Of Climate On Sediment And Reef Evolution Over Millennial Timescales

Climatic variability like precipitation changes or increase in extreme events such as storms and tropical cyclones is known to significantly modify the Earth’s surface. Yet, our understanding of how sediment dynamics and reef evolution might respond to these changes is still limited. In a recent study, a team of researchers from the University of Sydney’s … Read more…

Understanding the Deep Carbon Cycle from Icehouse to Greenhouse Climates

Sydney Research Excellence Initiative grant (2017-2018) Research area, key questions, significance, and innovation. The planet is experiencing a major transition from an icehouse climate, one dominated by permanent continental ice sheets at high latitudes, to a greenhouse climate that favours ice-free conditions. Although part of the deglaciation trend is influenced by a natural orbital cycle, … Read more…

EarthByte offers spatio-temporal modeling resources to researchers and the public

In 2016, the EarthByte group, based in the School of Geosciences at the University of Sydney, created a visualization tool and model to measure the interactions of arc volcanism with buried carbonate platforms in deep time. The new workflow tools, which are available to the DCO community, enable scientists to approximate paleo-atmospheric CO2 flux within … Read more…

Deep Carbon Modelling Workshop

Date:  August 29 – 30 2016 Venue: The University of Sydney Description: A two-day workshop bringing together climate and geo-scientists from around Sydney and international collaborators on the DCO-funded Deep Carbon Modelling project. Deep carbon science describes the multi-disciplinary effort to unravel the dynamic interactions of carbon-bearing systems in deep time. The workshop will focus on exploring the interplays … Read more…

Deep Carbon Modelling and Visualisation Project

The Deep Carbon Observatory (DCO) is a 10-year international research initiative to connect scientists from diverse fields and facilitate collaborative research and technology development in the field of deep carbon science. In order to address barriers to communicating the planetary carbon cycle to the public, a Modeling and Visualization workshop was held in May 2015 in Washington D.C. to bring … Read more…

Deep Carbon Observatory (DCO) proposal funded

Global plate reconstruction

A Deep Carbon Observatory (DCO) Proposal, designed to study the interaction of subduction zones with carbonate platforms through time in terms of CO2 cycles, submitted to the Smithsonian Institution and prepared to a large extent by Dr Sabin Zahirovic and EarthByte Research Assistant Jodie Pall, was successful, raising $US36k. The DCO actually doubled our proposed budget from … Read more…

EarthByters attend University of Sydney Open Day

Sydney Uni Open Day

We are very proud of our team of volunteers who represented EarthByte at the University of Sydney Open Day on Saturday. EarthByte had six volunteers who set up at 8am, and presented activities at the Eastern Avenue hands-on interactive stations until 4pm. This is a great outreach activity, and very reassuring to see the new generations get … Read more…
