Maps are used for more than just navigation these days. The citizen science projects highlighted below use maps to study topics ranging from wildlife to hydrology.

You can find even more mapping projects via the SciStarter Project Finder.

Cheers!

Learn how climate change affects plant life with AMC Mountain Watch

Track phenology events in Appalachian mountains and contribute to climate change research with Mountain Watch!

Want more spring citizen science? We’ve got you covered through April showers and May flowers.

There is nothing more rewarding than taking in the view from above tree-line. A challenging hike always seems like a distant memory after gazing upon the landscape below, especially if it’s the White Mountains of NH. Now, the Appalachian Mountain Club (AMC) is calling on visitors of these Northeastern peaks to help them observe plant life through the Mountain Watch program. This citizen science initiative aims to investigate how the life cycles of alpine plants are affected by climate change.

To do this, Mountain Watch asks participants to record plant phenology, which is the study of how plant life cycle events, such as flowering or producing fruit, are affected by changes in environmental conditions, including temperature and precipitation. Plant life cycles are very sensitive to small variations, so even subtle changes across seasons can be observed. For example, a dry summer might cause the leaves on trees to change color earlier in the fall. When recorded over many years, these phenology records can start to uncover long term trends in the climate and help scientists to model the effects of climate change in a certain region.

Since the AMC is based in the Northeastern portion of the Appalachian Mountains, the focus of Mountain Watch is on alpine plants that are found exclusively at high elevations in the north. The program is targeting these alpine species specifically because they have adapted to survive only in harsh, low temperature conditions and cannot thrive in warmer climates. As such, they are especially sensitive to climate change. Georgia Murray, a scientist a the AMC, describes that the Mountain Watch observations help to make up “really rich mountain data sets” that, paired with temperature observations from the Mt. Washington observatory, help to understand how climate change has affected the environment in the Northeast.

This year, the Mountain Watch program is joining an exciting new collaboration called A.T. Seasons (A.T. for Appalachian Trail), which is working to develop sites for citizen scientists to collect plant phenology data all along the Appalachian Trail. Mountain Watch joined this project to get more people involved, and as Georgia explains, to “utilize the A.T. as a north-south corridor in understanding phenology in climate change.” The goal of A.T. Seasons is to monitor the same type of plants along the whole Appalachian Trail to better understand the interplay of climate and phenology across geographical regions, as well as in relation to climate change. As alpine species only grow on the northern section of the A.T., they will not be included in this portion of the program; however, Georgia notes that Mountain Watch will still maintain the “alpine focus that is unique to the AMC and our region in the northeast” in addition to the A.T. Seasons plant list.

The incorporation of A.T. Seasons into the Mountain Watch program allows more citizen scientists to be involved, as the new initiative provides options for different levels of commitment – there is an Android app for easily making one-time measurements and more in-depth training courses for people who want to make long-term observations. The alpine flower portion of the Mountain Watch program does require more “dedicated volunteers,” as Georgia says, who can commit to regularly visiting the remote mountain sites, but there are many educational tools on the website for those who just want to learn more.

So grab those hiking boots and get outdoors! Spring and summer are the best times to observe plant phenology, and the sweeping views of the White Mountains await.

Getting flashed by the Moon?

By March 3rd, 2014 at 1:17 pm | Comment

Monitor the rates and sizes of meteoroids striking the moon with the Lunar Impact Monitoring project.

Citizen science after hours…here are some citizen science projects you can do at night.

Moon-craters

By now you’ve probably seen Gravity, and maybe you figured real astronauts don’t have to worry about projectiles, flying debris, or explosions. After all, the stars seem so calm from Earth, and the only turbulence we see on the surface of the moon are the waves breaking its reflection over the river. But sometimes, if you look long enough (even with the naked eye), you can spot a meteorite hurtling into Earth’s atmosphere with a flash. Approximately 73,000 lbs, about two large truckloads, of rock streaks through the Earth’s atmosphere each day. Earth’s atmosphere causes the meteorites to burn out before they do any damage, but the Moon has no protection against meteorites and neither do spacecraft or astronauts who might be working on or near the Moon. Potential for catastrophe? Worthy of little globes of Sandra Bullock tears? I’d say so.

To understand what risk these meteorites pose to spacecraft and their crews working in the lunar environment, astronauts have to know how often meteorites impact the moon, what size, and with how much force. Astronomers have been able to see the meteorites hitting the Moon for years – it doesn’t take much. When a meteorite strikes the Moon, it explodes in a flash that can be caught with only an 8 to 14 inch telescope and a clear sky. Since 2006, NASA astronomers like Rob Suggs say they “point telescopes at the night portion of the moon and record video from sensitive cameras,” which they analyze later. Simple as that, the Lunar Impact Monitoring Project at NASA was born.

Suggs says NASA began seeking out the help of citizen scientists immediately: “Many amateur astronomers have equipment similar to what we use.” By having more eyes on the moon, NASA can greatly increase the likelihood of seeing a lunar impact flash. The scientists want to be able to see as much as possible but sometimes, Suggs says, “we are clouded out or the Moon has set at our observatories while the Moon may still be visible from an amateur astronomer’s backyard.”

And sometimes amateur astronomers are the ones who end up seeing the impact. George Varros, a citizen scientist volunteer who has been involved with the Lunar Impact Monitoring Project since 2006, has already caught several impacts on camera. Varros first got involved with the project in part because of a lifelong love of astronomy, but he also says he recognized NASA was asking the amateur astronomy community to do “solid science, and it was not very difficult to do.” Even so, Varros says that the work “does take an effort and several hours, several nights, of imaging might elapse before you record [an impact],” but the wait is well worth it. Capturing an image, he says, is the best part. Already, the project has been able to catch the birth of a new crater and 300 flashes.

Once an image is caught on tape, NASA scientists can try to correlate the impact with a meteor shower they know about and use that information to learn the speed and size of the meteorite.  Often, these meteorite can fly through space eighty times faster than the fastest jet on Earth. So far, meteorites haven’t been known to destroy any spacecraft, but some people say that some in-space anomalies – bumps and bruises – have been from meteorites.

Whatever violence the rocks are causing up in space, lunar monitoring is still a peaceful experience from Earth. Suggs says it’s been thrilling to see impacts from the project and “seeing the new crater that Lunar Reconnaissance Orbiter detected from our March 17, 2013, impact was extremely exciting and satisfying.” But his favorite part of the project is still sitting out and watching the sky. Suggs says, “I enjoy the observing: just me and the telescopes and the Moon in the middle of the night.”
