Goldschmidt 2013 revisited

IMG_0150

The Goldschmidt blogging team have all had time to travel back to their homes, some even moving to a new country! We’ve put together our highlights from the conference, see them below. Feel free to add your own personal highlights in the comment section at the bottom! Enjoy

Emma

Though Goldschmidt2013 happened not even 3 weeks ago, it seems more like 2 months for me. Last week I spent in my home country, the Netherlands. Then I moved to Southern California and started a postdoc at JPL this week. Busy and exciting times!

Thinking back, two things really stood out for me at Goldschmidt. The first was meeting a “famous” colleague, who was very interested in collaborating on some of my samples. This is always the best about conferences I think, meeting new people, catching up with old friends, and talking about science. I’m always full of new ideas and motivations after such a week. The second was convening a session for the first time. We did our best to invite a diverse range of speakers, and I think it turned out a very interesting session.

AndyThere were so many highlights to this year’s meeting in Florence I have struggled to distil them to a workable number. Therefore I have selected my 3 favourite quotes from notes I made during Goldschmidt2013. In chronological order:

“Taking one river sample per month is like listening to Beethoven’s symphonies one note per minute” Jérôme Gaillardet

I mentioned this quote in another post during the week. It was taken from a presentation as part of the Critical Zone Observatory Open Forum Meeting on Monday evening. Jérôme was outlining the importance of holistic studies with thorough sampling to understand Critical Zone processes.

“Let’s skip all the details and go straight to the conclusions. That’s usually how I read a paper” Philippe Van Cappellen

Philippe, in his second keynote talk of the day (I know!), wanted to make sure the session got to the important aspects of several studies from his group. With a talk title of “Where Groundwater Meets Surface Water” there obviously needed to be a wide range of results presented to give a clear picture of this complicated environment. Philippe’s whistle-stop approach enabled him to get through a whole load of important processes, with clarity and without getting bogged down, refreshing!

“Icebergs are mobile MacDonald’s for phytoplankton in the Southern Ocean” Martyn Tranter

Also from a session’s keynote talk, this excellent turn of phrase evokes a mental image which has made Martyn’s Thursday afternoon talk stick with me for 2 weeks.

Along with the numerous Goldschmidt highlights there were areas for improvement… the main one, of course, was that we didn’t get Morgan Jones’ #OverlyHonestTalks theme running. This would be a trend on twitter where researchers present their results without the hype, for example:

“When two waters are mixed in different proportions, the stable isotopes of water form a line”@snowandscience
“The chemistry of a glacial river changes when the glacier melts” @drmorganjones
“Added acid to a solution and the pH went down…” @brayaw

Maybe next year…
Andy.

Once again, Goldschmidt flew by and two weeks later I still find myself thinking, “Darn! I missed that [talk, poster, person].” Oh, well. You can only do so much with 1 week, 4100 people and 19 simultaneous sessions. Nevertheless, there are some experiences that stand out when I look back on the whirlwind week in Florence:

Presenting in an all-female session on Monday (19e: Phototrophic life and Earth’s redox evolution) was a huge highlight. The session was organized by Jenn Macalady and Trinity Hamilton from Penn State and covered biomarker synthesis, stable isotopic signatures and redox cycling (Fe, S and Mn) mediated by phototrophs in analogue sites, laboratory experiments and geological samples. To see good science and representation by woman in this session was a welcome contrast to the predominantly male recipients of awards at Goldschmidt 2013, already mentioned by Emma Versteegh in her post on August 27.

Making connections with other scientists is always one of my favorite parts about Goldschmidt. One person I enjoyed meeting this year was Prof. Bill Gilhooly from Indiana University-Purdue University, Indianapolis (IUPUI). Bill gave an invited talk in session 3g (Reconstructing Ancient Surface Environments from Modern (Near) Analogues) on Friday about “ground-truthing” the multiple sulfur isotope signatures that are used to reconstruct past redox conditions based on his work in modern sulfidic sediments. We compared notes over dinner with a group one night about the complementarity between his work on sulfidic conditions and mine that is focused on ferruginous conditions. And of course “small world” syndrome set in after realizing my sister-in-law is a graduate student in his department.

Finally, I always appreciate the diversity of sessions at Goldschmidt and that it gives me exposure to research areas a bit removed from my own, or just new to me. This year I spent a lot of time in sessions that dealt with trace element distribution in sediments, seawater and marine biota, and Ocean Anoxic Events (OAE) (e.g. theme 17: Oceans and Atmospheres). It was great fun to observe what the hot topics are in these areas, but I did encounter some limits to my own knowledge: I’m still looking for someone to explain to me what is meant by the term “leaky bucket”!

SimonGoldschmidt2013? I am already thinking of 2014! But casting my mind back, it was a great meeting. Despite getting lost too many times among the lecture rooms in the basement, like some sort of minimalist maze where you never quite know which direction you are walking, it was a conference centre design like no other. If I felt in need of a workout, I simply took the long way round … walking from floor to floor via the never-ending external ramps.

As for Science … I enjoyed some great discussions over the poster sessions, sat through talks on planetary evolution in the early Solar System that blew my mind (without really working out how credible they were), and really appreciated the quality of so many of the presentations, especially from the grad students from our Department! It was a pleasure giving the citation for a colleague’s medal, meeting old friends in the beer queue and sampling some of the excellent food on offer in Florence. What a great city for a conference. I’m looking forward to future Goldschmidts, and must get back into the lab to collect the next dataset in preparation.

MattGoldschmidt2013 can be described by a few words: whirlwind, tiring, stimulating and most of all amazing. This was my second Goldschmidt conference and my first as a blogger. Actually, it was the first conference I have ever blogged and I have to say it made for a different feel. At conferences I have mostly gone to talks that apply to my own field in some way and thought about the science as it applies to my work. However, this time I had to look at talks through a second lens: that of a blogger/journalist. For the first time I was trying to think about more than just myself and my own work when viewing talks and posters. At this Goldschmidt I was trying to think about how the work of others could be distilled into a blog post, or how their work could interest readers. It made for a very new and interesting experience and I think it helped me get more value out of attending a conference than I have ever experienced before.

The highlights for me were numerous. Firstly, I loved giving my own talk! It was fun to get up in front of my peers and discuss the work that I and others in my lab have been doing on Fukushima iodine. I also enjoyed the other talks in my session and came away with lots of great ideas and possible collaborations. The second highlight was the Impacts of Geochemistry session. This session was tailor made for blogging and a lot of the talks were fascinating. The talk by John Ludden on the Geochemistry of London was very interesting, as was the talk by my old Prof Kurt Kyser on Geochemical Tools for finding Ore Deposits. The third highlight was the personal interactions. For example, meeting the other bloggers was great. We all were there for the same reason and it was great to interact on personal level as opposed to digital.
Here’s looking forward to next year in Sacramento!
Matt

Introducing the Bloggers of Goldschmidt 2013

It isn’t long until the start of the annual V.M. Goldschmidt conference, the main international meeting for geochemists to share and discuss ideas. This year’s meeting in Florence, Italy, is set to be one of the largest yet with over 4000 abstracts submitted. The European Association of Geochemistry and the organisers of this 23rd Goldschmidt meeting have assembled a team of writers from the geoblogosphere to cover the science and social activities of the conference. Here is that team, meet Andy, Betsy, Emma, Matt and Simon. Follow our coverage of Goldschmidt 2013 here on the EAG blog and on twitter, using the #Goldschmidt2013 hashtag.

Andy BrayAndy

University of Leeds, UK

I’m a Ph.D. candidate working in Cohen Geochemistry,School of Earth and Environment, University of Leeds, investigating the processes and rates of mineral weathering by soil dwelling micro-organisms. Generally, I’m interested in anything that involves life interacting with rock. That covers things from micron scale biogeo interactions, contaminant geochemistry, Critical Zone processes, global (bio)geochemical cycling and even a bit of astrobiology. In addition to my oral presentation (Thursday 16:45, 10j), I’ll be attending sessions with bio-geo themes and writing on some of the interesting presentations I see. I’m relatively new to blogging and alongside helping to set up the Cohen Geochemistry Users’ Blog, I (sporadically) post articles on the EAG Blog and Tumblr. I will be tweeting throughout Goldschmidt and you can follow me @Brayaw. Come and find me in Florence and talk to me about science or tell me a bad joke, either way I’ll enjoy it. See you at the icebreaker!

BetsyBetsy Swanner

University of TübingenGermany

Greetings from Tuebingen where I am busy preparing for this year’s Goldschmidt meeting. It will be my fifth trip to Goldschmidt, and is always one of the highlights of my professional year. It is however, my first experience as an official blogger, but I have gained some experience writing for the EAG Blog already this year. One of the aspects I am looking forward to most is convening a session for the first time – Session 9e: “Life in ferruginous settings: building the bridge between sedimentology and geomicrobiology”. You can find me at our posters on Wednesday afternoon (164 to 169) and the orals on Thursday afternoon (L05), along with co-conveners Nicole Posth of NordCEE-University of Southern Denmark and Bertus Smith of the University of Johannesburg. I will also be presenting my current postdoctoral research, which investigates the impact of Archean levels of dissolved iron on the growth of a marine cyanobacterium (Session 19e: Phototrophic Life and Earth’s Redox Evolution). See you in Florence! 

Emma VersteeghEmma

University of Reading, UK

I’m a post-doc working at the Department of Geography and Environmental Sciences, University of Reading. My current research focuses on carbonates produced by earthworms, and if they can be used as a proxy for past climate and environments. My broader interests range from stable isotope chemistry to marine ecology, palaeoclimatology and archaeology. Although I have written some short entries on my own blog Silent Witnesses and occasionally tweet as@emmaversteegh, this is the first time I’m having a go at blogging for a conference. Quite exciting! It is also the first time I’m convening a session, with my PI Mark Hodson: 19j The Role of Biominerals in Biogeochmical Cycling, in which Mark will present some of our recent findings on the role of earthworm-produced calcium carbonate in the terrestrial carbon cycle. I will present a poster on Wednesday on Pleistocene and Holocene Temperature Reconstructions Using Earthworm-Produced Calcite. I’m very much looking forward to Goldschmidt 2013 and hope to meet many of you there. 

MattMatt Herod

University of OttawaCanada

I am Ph.D. Candidate working with Dr. Ian Clark in the Department of Earth Science at the University of Ottawa. My research focuses on the environmental geochemistry of iodine and the radioactive isotope iodine-129. This work involves characterizing a 129I baseline in the Canadian Arctic and applying this to the transport and sources of 129I to remote regions as well as to long term radioactive waste disposal. I also work on the transport and fate of 129I from the Fukushima Daichii Nuclear Accident. At this Goldschmidt I’ll be found in aqueous and isotope geochemistry sessions listening to all of the great work that has been going on, and blogging about what I learn at my EGU network blog,GeoSphere. I’ll also be tweeting as @GeoHerod. My own talk is in session 18j: Geochemical and Biological Fate of Anthropogenic Radionuclides. I’ll be speaking on Thursday afternoon about my work on the rainout of 129I from Fukushima and its transfer into groundwater on the west coast of Canada. Hope to see you in Florence!! 

Simon RedfernSimon

University of CambridgeUK

I’m a Mineral Physicist, which means I enjoy applying an understanding of the properties of Earth materials at the atomic scale to a wide range of problems across Earth’s history, on global scale. By studying interactions across varying length scales and time scales I aim to understand how our planet works. I will be talking at Goldschmidt on Monday afternoon, about how synchrotron X-rays can be used to image the geochemistry of plankton calcite shells at the nanoscale. This year I have enjoyed a stint as a British Science Association media fellow, which has involved working at the BBC Science & Environment desk learning about science communication, and I also blog on the EGU network. All this activity started as blog at Geopoem for my students, and I post things there still. I’ll be tweeting, when I have a moment, as @Sim0nRedfern.

We’re aiming to provide a wide coverage of Goldschmidt 2013 via our blogging and tweeting, but make sure you also keep an eye out for the official press releases coming throughout the week.
