�Ӱ�pro

�Ӱ�prons can help the National Weather Service monitor rivers during a potentially dangerous breakup this year through a �Ӱ�pro citizen science project.



Deep snow and thick ice across much of �Ӱ�pro have this spring. At the same time, the coronavirus pandemic has limited the National Weather Service's ability to monitor conditions.

UAF’s citizen science project,, is recruiting community members to fill data gaps about spring river ice conditions in �Ӱ�pro.

Thanks to the Anchorage-based company, Axiom Data Science, the project already has a and mapping software where anyone can submit river or lake ice observations and photos.

“The best way for people to contribute right now is taking a photo and a little report,” said Karen Endres, a NWS hydrologist. She emphasized that providing regular reports, even when there is not currently any change, helps NWS predict how and when river breakup may progress.

“In our first year, we’re working with six different communities around the state," said project leader Chris Arp, a hydrologist at UAFs Water and Environmental Research Center. "Each has real time ice monitoring buoys along with river cameras, and youth groups who make field measurements. Our plan is to recruit six more communities to expand this program for next winter.”

In normal years, the monitors river ice conditions that feed sophisticated river break-up forecasts. �Ӱ�prons across the state rely on these forecasts for updates on river break-up timing and conditions.

This year is anything but normal. Thick ice covers �Ӱ�pro rivers, and a deep snowpack lies in the surrounding mountains. All that ice and snow is expected to melt rapidly, increasing the risk of dangerous ice jam flooding.

“UAF can fill gaps. We already have these tools built in. We can make a real difference here,” said Katie Spellman, Fresh Eyes on Ice project co-leader, ecologist and science educator at UAF’s International Arctic Research Center.

According to Spellman, stepping in to help fill gaps is not only the right thing to do but also a project goal. Fresh Eyes on Ice aims to provide data that make �Ӱ�prons safer while traveling on lake or river ice. When team members started the project, they didn’t anticipate NWS’ need for river observations; however, stepping up now could further promote ice-related safety. Through the website, �Ӱ�prons can contribute to forecasts that might forewarn of flood conditions like the ones that led to the catastrophic.

Contributing river ice observations is easy. Visit to submit a river location, upload a river ice photo and enter a short description of conditions. Observations can also be emailed to nws.ar.aprfc@noaa.gov or made over the phone by calling the National Weather Service, 1-800-847-1739.
