Antarctic ice sheet dynamics and evolution: a modelling perspective - Felicity McCormack (UTAS) »

3pm 25 September 2018

Antarctic ice sheet dynamics and evolution: a modelling perspective Antarctica is a dynamic component of the Earth system, modulating global mean sea levels on timescales of decades to glacial cycles. Here, I discuss the components of the governing equations for ice flow, including recent...

Haddon Forrester King Lecture: Porphyry copper, gold and molybdenum deposits – new geochemical exploration methods to aid discovery »

1.30pm 21 September 2018

In the past decade, significant research efforts have been devoted to mineral chemistry studies to assist porphyry exploration. These activities can be divided into two major fields of research: (1) porphyry indicator minerals (PIMS), which aims to identify the presence of, or potential for, porphyry-style...

Reconstruction of seawater 14C from a Porites coral living outside of the Runit Island Dome »

1pm 19 September 2018

After the WWII, Enewetak Atoll was used to test nuclear weapons; the program ran from 1948 to 1958. After an intermittent use from 1958 to 1972 it was decided to return Enewetak Atoll to the Marshallese after the establishment and completion of the clean-up operations. The island of Runit (on Eastern side of Atoll...

Ice sheets, climate, and sea level, from the past to the future »

2pm 13 September 2018

Even with government pledges to reduce greenhouse gas emissions as part of the Paris Agreement, we are likely committed to  3-4C surface warming above pre-industrial levels by 2100 CE, leading to enhanced ice-sheet melt. But the mechanisms by which the Greenland and Antarctic ice sheets advance and retreat differ,...

Ross Sea West Antarctic Ice Sheet History in the Late Cenozoic »

2pm 6 September 2018

International Ocean Discovery Program (IODP) Expedition 374 collected a latitudinal and depth transect of five drill sites from the outer continental shelf and rise in the eastern Ross Sea in January to March 2018. The expedition aimed to resolve the relationship between climatic/oceanic change and West Antarctic...

An adaptive vertical coordinate for ocean modelling »

5pm 4 September 2018

Ocean models are used in a large variety of applications, from research to industry: climate projections, shipping forecasts, or even enhancing our understanding of the physical processes. These models are numerical realisations of the physical equations, and by their nature there are limits on their precision. As...

Diamonds – time capsules of volatiles and the key to dynamic Earth evolution »

5pm 28 August 2018

Noble gases analyses of Mid-Oceanic Ridge Basalts (MORB) and Ocean Island Basalts (OIB) have been used to determine the present-day structure of the Earth. Noble gas elemental and isotopic data of these samples seem to support a two-layer mantle model, with a slightly degassed lower mantle and highly degassed upper...
