In this week’s edition of Who’s who in the Zoo Meg Schwamb tells us more about the Planet Four: Terrains project.

Project: Planet Four: Terrains

Researcher: Meg Schwamb, Assistant Scientist

Location: Gemini Observatory, Hilo, Hawaii


What are your main research interests?

I study how planets and their building blocks form and evolve, applying ground-based surveys to probe our Solar System’s small body reservoirs and citizen science to mine large datasets for Solar System science.


Who else is in your project team? What are their roles?

Candy Hansen (PSI) is the PI of the project, K-Michael Aye (LASP) & Anya Portyankina (LASP) are also members of the science team.


Tell us more about the data used in your project

The images reviewed on Planet Four: Terrains come from the Context Camera (CTX) aboard Mars Reconnaissance Orbiter (MRO). The Context Camera takes black and white wide view images (~30 km x ~60 km with ~6 m/pixel resolution) of the Martian surface that we cut into smaller chunks reviewed on the site.


How do Zooniverse volunteers contribute to your research? 

We ask volunteers to review the CTX subimages of the South Polar region of Mars and identify whether they see specific features: (1) araneiforms (including features with a central pit and radiating channels known as ‘spiders’) carved by carbon dioxide jets; (2) erosional depressions, troughs, mesas, ridges, and quasi-circular pits characteristic of the South Polar Residual Cap (SPRC) which we collectively refer to as ‘Swiss cheese terrain’, and (3) craters.


What have been the biggest challenges in setting up your project?

Figuring out the format and contents of the classification exports.


What discoveries, and other outputs, has your project led to so far?

Our first paper was accepted last year to a journal. Planet Four: Terrains has identified new regions of carbon dioxide jet activity including areas with jet carved channels (spiders/araneiforms) on geologic units previously thought to be resistant to the process (locations the spiders/araneiforms weren’t expected to be). More details here (http://blog.planetfour.org/2017/08/29/planet-four-terrains-first-science-paper-accepted-for-publication/).


Once you’ve finished collecting data, what research questions do you hope to be able to answer?

What is the distribution of aranaeiforms (spiders) over the South Polar regions? Why do we find araneiforms (spiders) in specific locations outside of the South Polar Layered Deposits?


What’s in store for your project in the future?

Expanding to a larger search area and exploring areas further from the South Pole of Mars to see how far North spiders may exist.


What are your favourite other citizen research projects and why?

I’m currently involved in several Zooniverse projects, so I think they are all my favorites: Planet Four, Planet Four: Ridges, and Comet Hunters.


What guidance would you give to other researchers considering creating a citizen research project?

Be cognizant that combining the multiple volunteer classifications together is likely very different from what you’ve done in the past for data analysis. Also, treat your project volunteers’ as your collaborators.


And finally, when not at work, where are we most likely to find you?

Baking and watching soccer (hoping the Chicago Fire make the playoffs).
