Beginning of my trip to New Zealand to attend the post-cruise meeting of our expedition to Zealandia. But first, visiting Bruce Hayward in Auckland. Thanks for great fieldwork and inspiring discussions on foraminifera!

A proper geography/geoscience exam paper from the all women Hitchin College (1871), the precursor to Girton College Cambridge. Several books to be written in answer to these. Just thinking if I can get away with some .... watch out first year Earth History students!

7/ .. deep sea carbonate buffer. Read all about it at .. Incredible job by Pincelli Hull with Andre Bornemann to pull a huge amount of data and diverse scientists into one cohesive paper.

6/ Ultimately we don't see any real support for the idea that Deccan volcanism contributed to the K-Pg mass extinction.. Unlike with earlier large volcanic provice eruptions (e.g. P-Tr), the earth's carbon cycle had an effective buffer for LIP CO2 emmissions in the form of the ..

5/ So, emplacement of the lava flows and CO2 outgassing (and thereby environmental effects) may not have been at the same time.. rather the majority of the CO2 could have escaped earlier (as argued by scientist Stephan Sobolev some years ago for the Siberian Traps)

4/ .. the pace of CO2 release was slow enough that the Earth's natural carbon cycling processes could draw it back down before the sudden impact at Chicxulub, when the extinction happened. This is despite dating of the physical lavas often being close to the extinction horizon.

3/ We compared this to various proposed models for how the Deccan Traps might have released greenhouse gases over the K-Pg boundary interval, and show that really while there was a warming event caused by CO2 release a few hundred thousand years before the boundary extinction, ..

1/ Our latest paper is out in today.. Along with a really nice new high-resolution K-Pg boundary section from the North Atlantic, with painstaking work from people a tonne of co-authors, we also compiled around 40 temperature proxy records..
