[Aqualist] Katrin Meissner seminar in Adelaide next Friday.

Fri Aug 14 09:52:18 AEST 2015

Dear AQUA listers,
As part of the Sprigg Geobiology Centre seminar series, there is a seminar next Friday which is bound to be a cracker…
“Modelling the dynamics of past climate change events”

A/Prof Katrin Meissner from UNSW Climate Change Research Centre.

Friday August 21, 2015, at 12:10 in the Mawson Lecture Theatre

Katrin’s research is described here:

Talk abstract
I will present climate model simulations of three different climate events in the past: the Paleocene-Eocene Thermal Maximum and Heinrich Events 1 and 4. The Paleocene-Eocene Thermal Maximum, ∼55 million years 
before present, was a period of rapid warming marked by a negative carbon isotope excursion and widespread dissolution of seafloor 
carbonate. These changes have been attributed to a massive release of carbon into the exogenic carbon cycle, and thus, the event provides an analog for future climate and environmental changes given the current anthropogenic CO2 emissions. Previous attempts to constrain the amount of carbon released have produced widely diverging results, between 2000 and 10,000 gigatons carbon (GtC). Sediment records 
indicate that acidification of deep waters was generally more extensive and severe in the Atlantic and Caribbean regions, with more 
modest changes in the Southern and Pacific Oceans. Here I will compare simulations integrated with the UVic Earth System Climate Model with reconstructions of temperature and sediment dissolution to present a mechanism that might explain the observed spatial differences and to constrain the total mass of carbon released. In addition, I will present a recent model - proxy data comparison during Heinrich stadials 1 and 4 (17.5-15.5ka BP and 40.2-38.8ka BP) with the isotope-enabled version of the UVic ESCM. Heinrich stadials were cold periods during the past glacial associated with major discharges of icebergs into the North Atlantic. We find that changes in surface (planktic) calcite d18O during these events can be equally attributed to changes in temperature (due to fractionation), changes in ocean circulation, precipitation and evaporation and to the addition of depleted freshwater from continental ice sheets. In contrast, the meltwater and circulation effects have only a small impact on benthic calcite d18O; significant changes in simulated deep ocean temperatures substantially influence

Please note that I generally only check email in the afternoon and so any reply may be delayed. Thanks.

Subject: Re: A short abstract?

I will be in a workshop the whole day tomorrow and won't see my computer (which has the presentation and everything else on it) until Monday. Would it be ok if I send it on Monday or would that be too late?

Cheers

Katrin

Dear Katrin,

I am very much looking forward to your Sprigg presentation next week and to discussing your research.  We’d like to publicise the talk in a few different places.  I wondered then whether you might have time to write a short paragraph describing the talk so I can include this information?

Kind regards,
John.

Dear all,

let’s change the title to “Modelling the dynamics of past climate change events”. This keeps all the doors open.

And I can certainly talk about several events, 50 minutes is quite long. 50% PETM and 50% O18 during Heinrich Events, unless there is interest in the carbon cycle and CO2 changes during Heinrich Events? If so, we could make it 25% PETM and 75% Heinrich Events including carbon, C14 and O18.

I am happy to arrive the day before, so that we all have time to meet one on one. I am really looking forward to this visit. :-)

Hi Katrin,

Thanks so much for getting back to us with a title. There is an active and vocal contingent here who very very much want to hear about isotope enabled models and Heinrich events, as do I.  If you can find a way to cover it all, we would be thrilled.  I am the main person interested in the PETM, so putting in a balance of topics as best you can would be very appreciated.  I realize it is only 50 minutes!  Thanks for being so nice about our tug-of-war on this end.  I think we all want it all!  I am ok with present title or something else if you want to modify.

Thanks and looking forward to having you!

Dear Cesca,

I promised you a title a long time ago :-). What do you think about: “The Palaeocene Eocene Thermal Maximum: An ancient analogue of modern climate change”? I will try to save at least 10 minutes at the end for more recent times, maybe a few slides on 18O enabled climate models and the simulation of Heinrich Events. Would that be of general interest?

Cheers,

Katrin

Dear Katrin,

It was great to speak with you on the phone and I am looking forward to having you come to Adelaide.  I will put you down for August 21 and we can arrange travel closer to the time.  The seminar is at 12 noon and thus you would be welcome to come for the day or come for a night, whichever works best for you.

In terms of the topic- as we discussed, I am very interested in the PETM, but I am starting to work on more recent timescales and there is also a large contingent of people working on more recent timescales (John Tibby and Jon Tyler, ccd here, to name a couple).  There is also a fairly large marine biology group and palaeontology/palaeoecology group.  It looks to me like you have worked on so many different things, so I guess I would be interested in what you are most interested in discussing?  If you are able to get us a title soon, then we can advertise your talk with the title on the schedule.

Thanks so much for being willing to come speak!

Cesca
