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...
East Asia northeastern monsoon variability over the past two millennia »
East Asia northeastern monsoon (EANM) is the downstream component of East Asia winter monsoon (EAWM) that influences the socio-economic activity of billions of people. Most detailed variations of past East Asia summer monsoon (EASM) have been reconstructed based on rain-bearing signatures retrieved by highly...
The future of ocean modelling - Markus Jochum (U. of Copenhagen) »
We can only trust current Earth System Models with future projections if they are able to reproduce past events. I will use model realizations of glacial inception and Dangaard- Oeschger events to illustrate what aspects of current ESMs are trustworthy and which ones need more work. Two...

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