Postcard from Tokyo: JpGU2018 conference

Postcard from Tokyo: JpGU2018 conference

Konichiwa from Tokyo and JpGU2018!

This week, 20-24 May, the Japanese Geoscience Union (JpGU) is holding its annual union meeting just outside of Tokyo, in Chiba (about 40 minutes by metro). I am fortunate enough to be on a research visit to the Earth-Life Science Institute (ELSI) at Tokyo Tech over on the other side of the city and so attending JpGU was a bonus. It is my first time in attendance and I was very interested to see the program and thematics, and meet some of the wider Japanese geoscience community.

 

JpGU poster and exhibitor hall

 

Being a national body there is naturally a focus on Japanese geoscience specialties and interests. Japanese language also featured heavily – at abstract the author selects which language the presentation will be in, as sessions can be English and/or Japanese – and attendees were notified in advance based on the final program’s language code. Last year there were over 8000 participants and 5,600 presentations, and the meeting is comprised of oral plus poster, and poster-only sessions. The meeting encompasses “all the Earth and Planetary Sciences disciplines and related fields” and would include Geodynamics under the “Solid Earth” section. Within this section there were 15 sessions (all in English), including Planetary cores: Structure, formation, and evolution; Probing the Earth’s interior with geophysical observation and on seafloor; Structure and Dynamics of Earth and Planetary Mantles; and Oceanic and Continental Subduction Processes, to name a few.

As with the EGU General Assembly, it is a five-day conference but notably shifted to run from Sunday to Thursday. While it was at the cost of a Sunday sleep-in, the weekend start meant that high school students were able to attend and even present their own posters. Some of the union sessions were also open to the public free of charge (so no doubt an unexpected windfall for some of the people at what seemed to be a furniture and toy convention next door). The week also included an awards ceremony, including the JpGU Union level “Miyake Prize” which was awarded to Professor Eiji Ohtani from Tohoku University. For the early career attendees, there were 5 minute pop-up bar talks for ECRs under 35 years of age with the lure of a free t-shirt and a beverage, as well as a student lounge.

 

JpGU2018 awardees and new Fellows

 

There were quite a few outreach and skill-building sessions, including “Mental care and Communication Strategies for Researchers”, “Kitchen Earth Science: brain stimulation by hands-on experiments,” “Role of Open Data and Science in the Geosciences,” “Employment and work balance of female geoscientists in Japan”  and an exciting “Collaboration and Co-creation between Geoscience and Art.” There were also a number of exhibitors including our very own Philippe Courtial, Executive Secretary of EGU who was a panel speaker in the AGU/EGU/JpGU joint session “Ethics and the Role of Scientific Societies – Leadership Perspectives”. I also found out there is a relatively new open-access journal for JpGU called Progress in Earth and Planetary Science (PEPS) (note, 1000 EUR APC for non-JpGU members or 200 EUR for members).

Science aside, my visit to Japan has been a multi-sensory delight and can only recommend coming back here in a scientific and/or tourist capacity! If you would like to combine your own travels with the next JpGU, the dates are:

  • May 26-30 2019, Chiba
  • May 24-28 2020, Chiba
  • May 30-June 3 2021, Yokohama

ありがとうございます!

Plenty of fabulous sights, sounds and smells!

 

 

 

 

 

To serve Geoscientists

To serve Geoscientists

The Geodynamics 101 series serves to showcase the diversity of research topics and methods in the geodynamics community in an understandable manner. We welcome all researchers – PhD students to professors – to introduce their area of expertise in a lighthearted, entertaining manner and touch upon some of the outstanding questions and problems related to their fields. For our latest ‘Geodynamics 101’ post, Fabio Crameri, postdoctoral researcher at the Centre for Earth Evolution and Dynamics (CEED), University of Oslo, Norway, joins us again. Continuing from his earlier post on the harmful use of the rainbow colour map, Fabio shares his thoughts on some of the expressions and phrases used in the community that propagate confusion, and how the new “Ocean-Plate Tectonics” concept offers relief for at least some on them. 

Blog author Fabio Crameri – in a shirt that translates from Tamasheq as “deserts” or “empty spaces.” You can expect no empty spaces in your lunchtime conversations after reading this post.

Do you, after reading the title, still wonder what this blog post is all about?
I’ll give you a hint, it’s about the Earth. No, wait, it’s about Earth, or perhaps earth, or isn’t it? And maybe it is a little bit about Moon, I mean the Moon. But also, it is about the Venus, I mean Venus.

It is not confusing, it is just well mixing.

You’ve got it; it is about confusion in the Geosciences. Confusion caused by symbols, letters, words and phrases through misuse, ambiguity or over-interpretation. So, after all, this is a blog post about geo-semantics rather than about culinary excursions.

The Geodynamics community is a diverse group of people with different backgrounds, native languages and customs. This is an attractive breeding ground for semantic related problems, particularly when you throw in some inherent peculiarities of the English language in which we largely operate.

Some use the symbol “a” for years, for years and years.

In line with a widely used standard definition (Holden et al., 2011) – but against the common convention of the Geosciences – the author of this blog post was using the unit of time “a”, or arguably just its symbol, for “years” (and I mean calendar years, neither financial years nor dog years), for years and years. A distinction between discrete points in time and the duration of time is at the heart of this confusion, and indeed has plagued a sub-selection of discussions, working groups and interpretations of the International System of Units (SI; e.g., Christie-Blick, 2012).

Figure 1. An ambiguously phrased situation near the recent end of the Cretaceous.

The symbol “a” for “annus” [year] (“Ma” being the symbol for 106 years, or “mega-annus”) in the Geosciences is most commonly used for a specific time or date in the past as measured from now. For example, “At 65 Ma (which is 65 Myr ago), the dinosaur looked up the sky.” (see Figure 1). On the other hand, “yr” for “year(s)” is commonly used for a duration of time, as in “The Cretaceous period ran for 79 Myr (from approximately 145-66 Ma).”. Other mutations within the convention of time in the Geosciences include “My”, “Myrs”, “Mya” or “m.y.” for “Millions of years”. Thus, the time unit and symbols for multiples of a “year” are likely amongst the most ambiguous expressions in the Earth Sciences, likely because, in contrast to the “second”, a universally applied scientific definition for the “annus” still remains elusive (Thompson and Taylor, 2008).

Such quibbling over semantics may seem petty.

Amongst other examples to cause geodynamic misunderstandings (e.g., Figure 2) might be the misuse of the phrase “stagnant slabs”? Are slabs ever really stagnant? Or are they just being deflected, slowing down, interrupting their downward motion, not directly entering the lower mantle at the same speed and trajectory as before?

Figure 2. One ambiguously phrased geodynamic explanation.

From the literature, you might be forgiven for having the false impression that slabs either fully stagnate around the upper-mantle transition zone or directly and effortlessly penetrate it; they likely do neither of the two (as explained in e.g., in an earlier Geodynamics101 post here).

When these slabs sink, and not temporally stagnate, they induce flow in the surrounding mantle. “Slab suction” is the downward suction induced by the nearby mantle that is set in motion through its dynamic coupling with the slab [e.g., Conrad and Lithgow-Bertelloni 2002]. Or isn’t it? “Slab suction” is also contrarily used as an upward directed force on the slab itself that is induced by the upper plate and might foster low-dipping shallow-depth slab portions in the uppermost upper mantle (unambiguously speaking of which: see again Figure 2).

The downward directed version of “slab suction” can induce “dynamic topography”. Estimates of the maximum amplitude of “dynamic topography” on Earth range from only a few hundred meters up to a few kilometres (see e.g., Molnar et al., 2015 and references therein). Such unusually large ranges of estimates are, as a general rule, a quite solid indicator for an underlying ambiguous definition, or in this case, rather a mix-up of multiple different definitions for the term “dynamic topography”. 

If you’re not confused, you did not pay attention.

As I keep talking about geodynamics, I hope we are all on the same page about subduction, one of the key players: Let’s assume planet XY has one single active subduction zone. Another subduction zone initiates on the opposite side of the same planet. Did “subduction” start once or twice on that planet?

It started once on that planet. Because “subduction” describes a process and not a physical feature; it is nonetheless easily mistaken for a physical feature.

And what about “plate tectonics”, the 50 yr old overarching concept that fascinates us, and for so many of us has become the foundation of our professional lives. Let’s approach this by considering the big question: When did “plate tectonics” start? Serious opinions in the plate tectonics community range from around 850 Ma (Hamilton 2011) all the way back to 4.3 Ga (Hopkins et al., 2008). – Remember what unusually large estimate ranges often indicate? – It is not surprising that the only commonly accepted specific answer everyone seems to agree on currently is that it depends on the very definition of plate tectonics.

So, what is the definition of “plate tectonics”? According to its original formulation, “plate tectonics” is the horizontal relative movement of several discrete and mostly-rigid surface-plate segments (Hess, 1962; see the corresponding visual representation in Figure 3). A generous interpretation of the original formulation might additionally define the plate-interface nature, but that is all.

Figure 3. As long as it is not overinterpreted, there is nothing wrong with the original definition of plate tectonics that solely describes the horizontal motion of several discrete surface plates: It does not discriminate the oceanic from the continental plate, does not consider the important framework of mantle convection, and does not specify the underlying key driver of the surface motion.

Considering the knowledge we have gained about the moving surface plates and their underlying causes and consequences during the past 50 yr, this is an extremely broad definition: As of today, we know that (A) the surface plates with their relative motion are an integral part of whole mantle convection (Turcotte and Oxburgh, 1972), that (B) Earth’s surface has a characteristic bimodal nature due to the partitioning into long-lived continental plates and short-lived oceanic plates (e.g., Wilson, 1966), and that (C) the latter are mainly driven by their very own subducted portions (i.e., all or parts of their slabs; Forsyth and Uyeda, 1975; Conrad and Lithgow-Bertelloni, 2002).

A clear, unambiguous and up-to-date definition for such a crucially important, wide-reaching concept is imperative. It is therefore not surprising that less ambiguous re-definitions have been suggested recently. To avoid propagating confusion, the introduction of alternative phases of plate tectonics that describe the various different possible modes of mantle convection during Earth’s evolution have been cast into the arena (e.g., Sobolev 2016). These include “plate-tectonics phase 1”, in short “PT1”, describing regional, plume-induced plate tectonics (e.g., until 3.0 Ga), “PT2” describing episodic, global plate tectonics (e.g., between 2.5-1.0 Ga), and finally “PT3” describing stable, global plate tectonics (e.g., 1.0-0.0 Ga). Other efforts result in different naming conventions, such as “modern plate tectonics”. However, apart from the fact that “modern” is a time dependent term, “modern plate tectonics” might be a somewhat unfortunate expression, as other planets like Venus might have undergone different, modern styles of plate tectonics than present-day Earth.

Stern and Gerya (2017) then actually suggests an entire update to the definition of “plate tectonics”:

“A theory of global tectonics powered by subduction in which the lithosphere is divided into a mosaic of strong lithospheric plates, which move on and sink into weaker ductile asthenosphere. Three types of localised plate boundaries form the interconnected global network: new oceanic plate material is created by seafloor spreading at mid-ocean ridges, old oceanic lithosphere sinks at subduction zones, and two plates slide past each other along transform faults. The negative buoyancy of old dense oceanic lithosphere, which sinks in subduction zones, mostly powers plate movements.”

Unfortunately, such a re-definition of the same old phrase makes it impossible to know which version of the definition (i.e., the original or the updated one) an author of a subsequent study should be applying and referring to.

In an effort to prevent all of the above problems, we recently introduced an entirely new concept; one that can coexist in harmony with the original definition; one that fully captures the dynamics of the oceanic plate according to our current knowledge. The concept is called “Ocean-Plate Tectonics” or, if you really like the term, “OPT”.

“Ocean-Plate Tectonics is a mode of mantle convection characterised by the autonomous relative movement of multiple discrete, mostly rigid, portions of oceanic plates at the surface, driven and maintained principally by subducted parts of these same plates that are sinking gravitationally back into Earth’s interior and deforming the mantle interior in the process.” – Crameri et al. (2018).

“Ocean-Plate Tectonics” captures not only the relative horizontal surface motion of plates, but crucially also accounts for (A) the importance of the whole mantle framework, (B) the bimodal nature of Earth’s surface plates, and (C) the underlying engine of the surface-plate motion (see Figure 4).

Figure 4. “Ocean-Plate Tectonics”, the unambiguous up-to-date definition describing the dynamics of the oceanic plate that crucially incorporates the bimodal nature of Earth’s surface, the convecting-mantle framework, and the key driver of surface-plate motion (after Crameri et al., 2018).

“Ocean-Plate Tectonics” is here to serve Geoscientists.

The concept of “Ocean-Plate Tectonics” is intended to bring together the extremely diverse research communities, but also the general public, to meet on common, fruitful ground in order to discuss and further develop our understanding of the fascinating dynamics involved in Earth’s plate-mantle system; the unambiguous “Ocean-Plate Tectonics” is here to serve us.

Meeting, mentoring and awards at EGU18

Meeting, mentoring and awards at EGU18

Having just about recovered from the session-packed, networking-fest, coffee-filled, schnitzel-test that was EGU2018 (8-13th April, Vienna), it is now possible to reflect and look towards upcoming dates. Earlier posts in the blog have described some of the GD side event highlights. For this week’s post, I have summarised some key points from the GD Division meeting, the EGU Mentoring program, and the upcoming EGU award nominations.

Geodynamics (GD) Division Meeting

During the Friday lunchtime break GD President Paul Tackley (ETH Zürich) led the session about GD activities and statistics to an eager audience of around 50 attendees. Within the 19 GD-led sessions for EGU2018 there were 481 abstracts (adding co-organized sessions raised this to ~1450 abstracts). As in previous years, the structure of EGU, and meeting fun facts were delivered – this year there were over 15.000 attendees, 17.000 abstracts in the programme, 666 unique sessions and 68 short courses. New to this year’s conference, there was a Cartoonist and Poet-in-residence, re-usable water bottles, and CO2 emission offset initiative.

A portion of the lunchtime meeting was dedicated to discussing the time and space constraints associated with increasing attendance and presentations at the GA. Many rooms are already overcrowded and maximum poster capacity is expected to be reached within the next 2 years (this year 8% of GA presentations were PICOs, 64% posters and 28% orals). As extra space in the Austria Centre Vienna is not a possibility, several ideas were put forward by EGU including increasing the GA from 5 to 6 days, limiting to 1 abstract per person (2 if invited), increasing oral times from 6-8 hours per day, holding different posters in morning and afternoon, and shorter talks (12 minutes). Several audience members expressed opinions regarding the proposed changes, and the audience seemed in favour of more overall oral time-slots but not shorter talks, or moving to a 6 day conference. We shall see what is implemented but there are at least new set of rules for 2019:

Apart from the consumption of free sandwiches, audience arms were put to use when voting for Division Officers (van Hunen, Artemieva, Biggin, Bunge, Karato) and the Medal Committee (Houseman, Parmentier, Parsons, Phipps Morgan) – all approved.

For the GD ECS specifics, we will welcome the new GD Early Career Scientist (ECS) Representative Nicholas Schliffke (U. Durham), as Adina Pusok (UC San Diego) steps into a co-representative position for the next year. Our blog activities over the last year were also presented by our enthusiastic Editor-In-Chief Iris van Zelst (ETH, Zürich). As always, we encourage more ECR members to get in touch with us to be a guest writer.

Some important EGU2019 dates for your calendar:

25 June-13 September 2018
Public call-for-sessions
(the rolling over of sessions will not occur – join forces with your colleagues!)

15 October 2018 – 10 Jan 2019
Abstract submission

7-12 April 2019
EGU2019, Vienna

EGU GD Awards

The Meeting also highlighted the Division’s 2018 award recipients, Edgar Marc Parmentier and Thibault Duretz, which we here congratulate again:

The GD Outstanding Poster/PICO (OSPP) for 2017 was awarded to Ludovic Räss for his poster “M2Di: MATLAB 2D Stokes solvers using the finite difference method.”

In particular, please note the upcoming deadline for award nominations for 2019 on the 15th June.
We encourage you to put forward your colleagues for nominations for both categories! You can read more about the awards and nomination process here.

And with only a single female winner of the GD Outstanding Early Career Scientist Award (<7 years from highest degree; no age limitation), and none for the Augustus Love Medal, I am sure you do not have to look far for worthy candidate(s) to help improve the gender balance of these awards.

Mentoring program – we need you!

In its second year running, EGU organized a mentoring program during the conference. This year the program received double the number of registrations from 2017. The aim is to connect mentors – those who are EGU veterans in terms of multiple attendances – with mentees, prioritized to early-career participants (Masters and PhDs) who are first-time attendees. Matching was primarily based on division affiliations or research keywords, but as there are 22 divisions and over 50 identified research interests, interdisciplinary matches were commonplace.

This year from GD specifically there were 3 mentors and 2 mentees signing up – as EGU Media and Communications Officer Barbara Ferreira said “a rare (and positive) case of more mentors than mentees registering for the programme”. These 3 mentors were eventually matched with 6 mentees. However, across the board around 75 mentees had to be rejected because of insufficient mentors available.

So, if you have attended numerous EGU GAs and know the lay of the land, please do sign up next year! I can highly recommend being a mentor; to sit down for a coffee and a chat is really not taxing and is a good opportunity to meet new faces in your division and from further afield.

 

Tschüss – see you in Vienna next year.

Editorial thanks to GD President Paul Tackley and EGU Media and Communications Officer Bárbara Ferreira (@dinnerpartysci) for summary slides for the GD Meeting and Mentoring programs, respectively. Cheers again to the EGU organizers for a fantastic meeting.

Making the most of the EGU General Assembly 2018 as a Geodynamicist and Early Career Scientist

Making the most of the EGU General Assembly 2018 as a Geodynamicist and Early Career Scientist

Are you still deciding on how to best fill your EGU General Assembly program next week in Vienna? Wondering what is on offer specifically for the Geodynamics (GD) early career community? Our EGU GD Early Career Scientist representative, Adina Pusok (Scripps, UC San Diego), shares some planning tips and event highlights for the big week ahead. We are looking forward to seeing you there!

The EGU General Assembly 2018 (popularly known as EGU2018, or the official hashtag of #EGU18) in Vienna is about to kick off this coming Sunday, and I am sure many geoscientists worldwide are making the last preparations, or even getting the last results in (good luck!). Hopefully, some of you have already had a chance to look on the EGU2018 meeting organizer available (also with a great mobile app) and “star” some of your favourite sessions and events in your personal programme. And probably soon enough, you have also realized that it is not humanly possible to attend everything that you find interesting (unless you are in possession of a time machine to be in multiple places at the same time).

A meeting the size of EGU2018 can be intimidating to most attendees, especially first timers, and being selective becomes a valuable skill. It is a place where you can check out the latest research across a wide range of fields within the geosciences, and within your own area of science. And of course, it is a place to catch up or make new friends and collaborations from all over the world.

Assuming that you’ve already marked in your personal programme your own presentation(s) and scientific sessions of interest, I want to draw your attention to the other side of the conference. The EGU2018 is not just a conference where the latest science is reported, but also one of the best places where you can develop your personal and career skills in a short amount of time. As I’ve written before, Early Career Scientists (ECS) have different needs compared to established scientists. And for that, the EGU2018 schedule comes with a wide range of sessions, short courses, great debates, union wide events, and division social events that complement the scientific agenda of the meeting.

I write this blog post primarily for Geodynamics ECS and first time attendees at the EGU2018 to help them navigate through this “hidden” schedule and make the most out of EGU2018. As an ECS myself, I’ve always liked to explore what every meeting has to offer, and try to learn some new things. So, here are some of my tips and highlights for this year’s EGU2018 meeting schedule:

  1. Short courses – learn a new skill or two in no time

    Learn a scientific skill:
  • Geodynamics 101 (Figure 1) – First short course on numerical geodynamics at the EGU General Assembly! So it’s a must whether you are a geodynamicist, or you just want to understand why all those pretty pictures also make sense scientifically (Wed, afternoon)
  • GPlates – Try this hands-on tutorial with a popular open-source software for plate tectonic reconstructions (Thu, morning) 
  • Seismology for non-seismologists – Learning how to correctly interpret seismic data is an important skill for every solid-earth geodynamicist (Mon, afternoon)

For first time attendees:

  • How to navigate EGU: tips and tricks – Dedicated to first time attendees! If you fit the bill, make sure you wake up early on Monday morning for this introductory short course (Mon, morning) 

Learn to polish these professional skills:

  • Academic presentations – Having last minute nerves about your presentation? Get some tips and tricks to ace that talk! (Mon, afternoon)
  • How to convene a session at EGU’s General Assembly – Convening a session is regarded as an important duty in the scientific community that also gets you a free ticket to the conveners’ party on the Friday evening (Tue, afternoon)
  • How do you peer-review? – Something that nobody during your graduate studies will actually tell you, but you’re expected to know how to do.
  • Applying for Marie Sklodowska-Curie grants – Info session on the highly competitive individual fellowships that are definitely worth applying for, and are aimed at Early Career Scientists (Wed, lunch) 
  • ERC grants – More funding opportunities from the European Research Council (ERC) at all career levels (Thu, evening) 

Explore outside your bubble:

  • Academia is not the only route – Are you finishing your degree and not overly excited by an academic future? Try this short course on exploring career alternatives both inside and outside academia (Thu, afternoon) 
  • Unconscious bias – Become aware of the obstacles that some of your colleagues face every day, and that might prevent them from doing the best science (Tue, morning)

Learn how new technology can help your research:

  • Writing reproducible science – You know you’ve complained at least once that it’s difficult to reproduce the results of a certain paper. Now you can learn ways to improve the conduction and dissemination of your work! (Thu, afternoon)
  • Learning git – This is a life-saver skill that every scientist should have! No more n-versions of your theses, manuscripts or projects (Wed, morning)

Fun skills:

  1. Great debates – teams argue opposite views on a particular topic. Let’s see some science-worthy arguments there!

Don’t worry if you cannot (really) make it to the great debates. You can follow and join in the debates using the web-streaming service.

  1. Awards events – Come and celebrate the work of distinguished scientists! Tip: Medal lectures are particularly interesting across all geosciences fields! This year’s medal lectures specific to the GD division are:
  1. More events and sessions dedicated to professional and career development:
  • EarthArXiv – A general introduction to preprints and the new pre-print server for Earth Sciences, a concept that has been very successful across science disciplines (Mon, evening)
  • Industry career opportunities for early career scientists – The title is clear enough of what you can expect here: how to transition from academia to industry (Mon, evening) 
  • Promoting and supporting equality of opportunities in geosciences – If you care to promote an open, equal opportunities working environment (and you should!), this session promises some very interesting talks and posters on some common issues, solutions and initiatives (posters – Tue, morning, orals – Wed, afternoon) 
  • Meet the chief executive editor of Solid Earth – Thinking of submitting your next manuscript to an EGU journal, such as the Solid Earth? Learn tips and how the publishing process works by meeting the editor–in-chief of the journal (Mon, afternoon)
  • Games for Geoscience – Because it’s always more fun to work and play (orals and posters – Wed, afternoon) 
  1. Other ECS events – Get active and involved into the EGU ECS community with these events:
  • Meet the EGU ECS Representatives and EGU Communications Officer (Roelof Rietbroek, Stephanie Zihms, and Olivia Trani) – These are the people representing ECS at the union level and will be happy to chat with you about your EGU experience, or future plans for the ECS community! (Wed, afternoon)
  • EGU ECS Forum – Open-discussion session for all ECS. Lunch provided! (Thu, lunch)
  • Imaggeo photo competition – Announcing the winners of the photo competition. High-quality photos guaranteed! (Fri, lunch)
  1. Union wide events – Great events to network with medalists or other scientists over some food and drinks! Do not miss them!
  • Opening reception – Sun, 18:30–21:00
  • EGU Award Ceremony – Wed, 17:30–20:00
  • ECS Networking and Careers Reception – Mon, 19:00–20:30
  1. Geodynamics and ECS events
  • ECS GD informal lunch* – Meet in front of the conference center (look for “GD” stickers), to head to the food court in Kagran (2 subway stops away from the conference center). Looking forward to meeting many ECS and come up with more exciting projects for GD! (Note: this blog started taking shape at the ECS GD lunch last year) (Tue, 12:00-13:30)
  • ECS GD dinner* – Join us for a friendly dinner with fellow ECS Geodynamicists at Wieden Bräu – Waaggasse 5, 1040 Wien!
