Hi @wassock,

Yeah it's kind of a natutal inherent problem in Talk with the free form hashtags. We have the same issue on original Planet Four Talk, with boulders versus boulder and blue versus blue frost. It's a bit bigger as you've noticed because the most popular hashtags don't show up on the subject pages where you make the notes posts and start subject discussions, and I think that helps create a common lexicon. That should be a feature added in the near future soon, which should help.

I found that you can usually do a decent job or grabbing everything on the backend side database side depending on what your needs are for the hashtags as long as someone else added one more common hashtags after use. Because the Talk database hashtag information can be searched to return back the most common tags for what feature you were looking for and all other hashtags associated with those images to find the blue_ford versus ford_blue for example. Also in searches returning back the most common other hashtags associated with the hashtag you're searching for might help. Talk 2.0 does this, and it's something we could ask for as a feature request, once the next Talk development sprint is over in a month or so.

But you do need to then have had someone else apply the more common tag to the image. I like to say that Talk finds interesting things and samples that you can't find from the classification interface, but it's not a complete search since someone has to add a hashtag and as you point out, you have to figure out which ones represent what you're looking for.

I think it's a great idea to try and cleanup hashtag usage and promote a set of hashtags for Planet Four: Terrains and also Planet Four if as well. if you want to come up with a recommended list, I can find some example images and I can post it to the blog.

Cheers,

Inca City. Maybe because I've seen it most, or because it was my first contact with Martian science. But also because of it's intriguing geomorphology and the funny boulders lying around. The rectangular shaped basins at Inca City make up for some pretty peculiar illumination scenarios that can explain the location of fan activity centers. This topic will be discussed as part of an almost finished paper of Anya and me that we will continue to work on right after we submit our first P4 paper.

Quote from NASA
Above the surface, scientists discovered Pluto’s atmosphere contains layered hazes, and is both cooler and more compact than expected. This affects how Pluto’s upper atmosphere is lost to space, and how it interacts with the stream of charged particles from the sun known as the solar wind. “We’ve discovered that pre-New Horizons estimates wildly overestimated the loss of material from Pluto’s atmosphere,” said Fran Bagenal, from the University of Colorado, Boulder, and lead author of the particles and plasma paper. “The thought was that Pluto’s atmosphere was escaping like a comet, but it is actually escaping at a rate much more like Earth’s atmosphere.”

They over estimated the loss rate by a factor of 10,000. That's pretty significant but it just means they were misunderstanding the situation.
I really don't see any evidence at all supporting this methane explosion idea on Pluto.

Methane has been trapped in the permafrost of Siberia for millennia yet these explosive craters have only been occurring recently as the result of global warming.
Pluto is not globally warming and there are no holes like this, that I can see, anywhere on the surface.

It is a truly fascinating phenomenon but it belongs/occurs here on earth.

Methane is found in the atmosphere of Pluto at relatively high rates compared to the nitrogen.
The temperature at high elevations drops to much colder levels which in turn condenses the methane back into a snow that drifts back to the surface.
Pluto has season as it runs in and out of perihelion and aphelion. This means for 124 years Pluto will have more methane in its atmosphere than for the next 124 years as it orbits around the sun. Even during the time large quantities of methane are in the atmosphere they will condense and fall back to Pluto.

I think scientist saw the quantity of methane in Pluto's tenuous atmosphere and assumed it was all escaping to space.
We have since measured the temperature of the atmosphere at various levels and now understand the cold is returning the methane to Pluto.

Very cute!

“A motion-capture camera in Boulder, Colo., snapped hundreds of images of a curious black bear in November, local officials say.

“The city's Open Space and Mountain Parks department set up nine of the cameras to track and learn about local wildlife species while minimizing the presence of humans in sensitive habitats. One of the cameras had captured about 580 images — and about 400 of them were of the same bear.”

CU Boulder Mason Bees - Measurements workflow in Notes from Nature - Big Bee Bonanza! project. There are 11 subjects still to retire.

This project has multiple active workflows, so please go to the "Get started" section of the project home pages to select this workflow. (Of course, we'll be happy to have your classifications in any of the other workflows too.)

Please read the field help and tutorial if you haven't worked on our bee measurement workflows before. The Field Guide also has a link to a video showing the measurement process, which you may find useful.

Awesome response people! Thanks! The CU Boulder Mason Bees - Measurements workflow in Notes from Nature - Big Bee Bonanza! project is now complete.
