Inverting the amplitude and source of Meltwater Pulse 1A using sea-level constraints »

12pm 13 March 2019

The source of Meltwater Pulse 1A (MWP-1A), the largest and most rapid global sea-level rise event during the last deglaciation, is important for understanding large ice sheet stability, global sea-level budget and climate change during last deglaciation. However, the source of this event is still debated,...

Climate tipping points: implications of paleo-climate records »

1pm 7 March 2019

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...

Is XRF core scanning a viable method for coral palaeoclimate temperature reconstructions? »

11.30am 6 March 2019

The use of X-Ray Fluorescence (XRF) Core Scanning for continuous high-resolution analysis of Sr/Ca in corals is investigated here as a new method for analyzing coral material. Corals are valuable archives for generating high resolution palaeoclimate records of sea surface temperatures of the tropical oceans, but...

Crater Counting using Machine Learning »

1pm 28 February 2019

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 »

27 February 2019

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) »

2pm 26 February 2019

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 »

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...
