Doors held ajar in storms: Insights into Atmospheric Planetary Science »
Our spacecraft have taken us to visit and explore many stark and ancient landscapes in the solar system. At first glance, very little appears to have changed for billions of years, but if we look to the atmosphere we see a dynamism that belies active processes in the present era and that hints at changes at and...

Lessons from the Sudbury impact structure for the Hadean Earth »
We know little about the Hadean Earth but most agree that the entire inner Solar System was pummeled by impacting bolides. None of the terrestrial Hadean impact basins are preserved but by analogy with our neighbours, the Earth must have featured basins of up to thousands of kilometers across. Is there any hope of...

What have we learned about Earth from space gravity missions? »
In 2002 the Gravity Recovery and Climate Experiment (GRACE) mission was launched, with the specific aim of measuring Earth’s gravity field and its variation with time, with unprecedented accuracy. The mission was an outstanding success, with impacts in a broad range of disciplines including oceanography,...

Climate tipping points: implications of paleo-climate records »
Important lessons regarding current and future climate change trends can be derived from the paleo-climate record. Particularly from abrupt events such as the Oldest dryas (~16 kyr), Older dryas (~14 kyr), Younger dryas (12.9–11.7 kyr) and the ~8.2 kyr Laurentian ice melt event all of which...

Crater Counting using Machine Learning »
Crater counting provides a relative timeline of the geological history of a planetary surface [1]. If an absolute age can be accurately attributed to a surface, the crater counting timeline can be calibrated, providing specific age information for a variety of features. This is available for the moon due to the...

Seafloor hydrothermal systems of intraoceanic arcs »
Scientific discovery of submarine hydrothermal systems associated with intraoceanic arcs, and to a lesser degree backarcs, has been continuous and largely systematic since the first methodical survey in 1999 of hydrothermal plumes discharging from volcanoes of the southern Kermadec arc. Around 150 volcanoes have...

Changes in the width of the Indo-Pacific tropical rain belt from climate model simulations and palaeo proxy records »
The Indo-Pacific tropical rain belt (TRB) marks the high-rainfall region in the tropics traversed by the seasonal migration of the intertropical convergence zone. In particular, changes in the position of the northward and southward edges of the TRB can have considerable impacts on natural and human systems across...

Multiple Sulphur Isotopic Compositions of Archean Records »
Multiple Sulphur Isotopic Compositions of Archean Records
Sulphur is closely related to life, environment, and mineral deposits. Multiple sulphur isotopes are a significant tool of recognizing the earliest sulphur-utilizing metabolisms on the Earth, reconstructing the Archean atmospheric oxygen level, and...

A continuous ice core record of climate to beyond a million years »
Ice cores from Antarctica, Greenland and mountain glaciers have provided great insights into climate on timescales from seasonal to glacial and geographic scales from regional to global. The rich archive of environmental tracers recorded in the snow makes ice cores arguably the most powerful single recorder of past...

Studies of water on Earth and in the asteroid belt »
It is increasingly accepted that the fast diffusion of water in glass renders measurements of melt inclusions suspect except in very small tephra. Therefore there is much interest in the use of water measurements in nominally anhydrous minerals such as clinopyroxene and application of a partition coefficient as...

Ocean Fertilization by Natural and Anthropogenic Nitrogen Input in the Past and Present »
The availability of “fixed” nitrogen limits the growth of marine phytoplankton in large part of the ocean. It has been suggested that considerable changes in nitrogen inventory could occur in the recent past or in the future, which may change the fertilization of the ocean and drive significant changes in...

Geologic History Of The Wyoming Province, One of the Oldest Fragments of Crust in the World »
The Wyoming province consists of Precambrian rocks that are exposed in the Laramide uplifts in the Rocky Mountains of Wyoming. The province records a long history with rocks dating back to 3.4 billion years ago (Ga) and xenocrystic zircon grains dating to ca. 3.9 Ga. Lu/Hf ratios on some of the xenocrystic...

2018 RSES PhD field trip to the Northern Territory, Australia »
This September, 17 research students from the Research School of Earth Sciences (RSES) had the incredible opportunity to explore the geology and cultural history of the Northern Territory. We spent two weeks driving through northern and central Australia, travelling over 4000 km in total! This trip provided an...

The Miocene is the Future »
To better understand and predict future climate change we often to look to past periods of global warmth as analogues and testbeds for models. The Miocene (23 to 5 million years ago) is probably the best analogue for the range of carbon dioxide concentrations, warming, sea level rise, and ice volume losses that...

An extended record of Indian Ocean Dipole variability from Indonesian Corals »
The Indian Ocean Dipole (IOD) is an ocean-atmosphere climate oscillation within the Indian Ocean basin and one of Australasia’s key climate drivers that influences the distribution of rainfall across the region. Future projections of IOD activity suggests that extreme positive IOD events may become more frequent...
