Seafloor hydrothermal systems of intraoceanic arcs »

1pm 21 February 2019

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 »

1pm 14 February 2019

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...

The coupling of carbon cycle and AMOC - a multi-proxy study in the mid-depth subpolar North Atlantic since 65 ka »

12pm 13 February 2019

Abrupt climate oscillations during the last glaciation provide important insights for the ongoing rapid climate change. The strength and pattern of Atlantic Meridional Overturning Circulation (AMOC) are thought to play significant roles in the repeated millennial transitions between cold stadials and warm...

Reframing the carbon cycle of the subpolar Southern Ocean - Graeme MacGilchrist (U. Princeton) »

10am 12 February 2019

Global climate is critically sensitive to physical and biogeochemical dynamics in the subpolar Southern Ocean, since this is where the deepest, most carbon-rich layers of the world ocean outcrop and exchange carbon with the atmosphere. Here, we show that the conventional framework for the subpolar Southern Ocean...

Did solar forcing influence the Southern Annular Mode over the Last Millennium? »

12pm 6 February 2019

The Southern Annular Mode (SAM), also known as the Antarctic Oscillation, is a primary mode of climate variability in the Southern Hemisphere and has major climatic influences for Australia. A positive trend in the SAM can be seen in recent decades in both observational records and climate simulations, and proxy...

Multiple Sulphur Isotopic Compositions of Archean Records »

4pm 11 December 2018

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...

An Arctic gateway trigger for Atlantic overturning at the Eocene-Oligocene Transition »

2pm 30 November 2018

The Eocene-Oligocene Transition (EOT), approximately 34 Ma ago, is an interval of great interest in Earth’s climate history, due to the inception of the Antarctic ice sheet, major global cooling, and the likely inception of North Atlantic Deep Water. In line with geological evidence that the Arctic became isolated...
