Letter from the Executive Director 


Dear Friends of Water Science:

We are continually working to improve user experiences with CUAHSI Data Services. We recently concluded a project with Texas Advanced Computing Center’s (TACC) Expanding Pathways in Computing (EPIC) STEM Evaluation Services. The purpose of the project was to provide an independent review of HydroShare user experiences. The full report is available on HydroShare here. One of the highest priority recommendations was to “Provide more resources on how to use HydroShare, such as video tutorials or one-page guidelines
that succinctly provide necessary information for using a particular feature.”

In response to that recommendation, CUAHSI has been creating short, two - three minute How To videos to help users understand HydroShare’s capabilities and get the most out of their experiences on HydroShare.  The current playlist includes seven videos, including how to set resources as public, private, or discoverable. We hope you will find these videos useful. Please give us feedback and request new videos at Along with this effort, we have updated HydroShare help documentation which more closely aligns with current HydroShare capabilities. 

Take care and let us hear from you on how we are doing.



Voices From The Community 

Snow Hydrologist and Postdoctoral Research Fellow 
US Army Corps Engineer Research and Development Center (ERDC)
Coastal and Hydraulics Laboratory (ERDC CHL) and Cold Regions Research and Engineering Laboratory (ERDC CRREL)

In August 2021, after what seemed like a very long time, I finished my PhD in Snow Hydrology at the University of Alaska Fairbanks. With lots of work and a little luck, I secured funding from many sources to pay tuition and conduct remote field work here in Alaska. In 2016, I received a CUAHSI Pathfinder Fellowship, which was a critical component of my field work in the Brooks Range. Field work in the vast and often harsh landscape of Alaska is expensive; financially, physically, and emotionally. The work can involve small planes, helicopters, motorized or non-motorized boats, and snowmobiles. It’s really cool, but these experiences also serve as reminders of the value of quality remote sensing and spatial modeling in our hydrology research. 

When I was growing up in rural upstate New York, I somehow got my hands on a National Geographic photography book of US National Parks. I became obsessed with working in several of these parks in Alaska, including Gates of the Arctic National Park and Preserve. Twenty five years, countless seasonal jobs all over the western US, and several college degrees later, I finally realized my dream of working in Gates, as a PhD researcher studying perennial snowfields. I’d like to think that I’ve learned a lot about water resources during my decade here, but sometimes the more you learn, the less you know. I also used to think I was pretty tough, but Alaska cured me of that line of reasoning.   

This place is the land of contradictions, dichotomies, and extremes. Making a life in Alaska requires a little extra grit and a lot of patience. For example, snow melt feeds rivers, lakes, and recharges groundwater. This sustains wildlife, plant life, and the lives of the people who depend on these animals and plants. However, the same life sustaining snow melt can turn into deadly avalanches and village-destroying river flooding. Seasonal snow, which blankets the Alaskan Arctic in winter, and perennial snow, which persists throughout summer, are vital to the movement of caribou. Snowmelt also waters the lichen that these caribou eat. 

Before moving to Alaska, I was convinced that this place was an empty, uninhabited land (and thus, part of the appeal). However, I couldn’t have been more wrong. During my time studying snow in Alaska, I’ve met a dazzling array of different people and seen how rich with culture and tradition this land is. Much of this culture is in sync with the rhythm of the hydrologic cycle. I have been fortunate to have the opportunity to learn from, and share my research with, the Nunamiut Iñupiat, a local community of Alaska Native people who live in the Brooks Range and depend on caribou for subsistence hunting and other traditions. 

I think the biggest lesson I learned as a PhD student was that snow and water not only shape the landscape and sustain biological life, but that they also shape and sustain culture and traditions. At the beginning of my CUAHSI fellowship, my dream was to see the iconic mountains of the Brooks Range and gain an understanding of snow mechanics and alpine hydrology. What I didn’t expect was to meet some of the toughest and most welcoming people ever. I hope that I’m steadily acquiring some of their Alaskan grit.
General Announcements

We recently sent CUAHSI Member dues invoices to CUAHSI Member Representatives. Thank you to those of you who have responded promptly. 

Membership dues are a small part of CUAHSI’s income, but an important part. These funds allow us to pay indirect charges to grantors, particularly donor foundations, who restrict indirect rates to less than our federally negotiated rate.  Moreover, your membership allows the community to stand united as we seek to advance hydrologic science and support access to the latest science and data for everyone. CUAHSI also offers discounted rates to any individual from a Member institution to CUAHSI events. Remember that you can pay for five years of membership in advance and receive a 10 percent discount. Please contact Maddie Scranton ( ) if you have any questions or to make your payment.
We’ve been working on a new and enhanced CUAHSI website that better promotes the CUAHSI brand and makes it easier to learn about our programs and services. Keep an eye out for the website launch in the next few weeks!

For Instructors and Students 

Hydrogeodesy in the Field and Beyond: Observing Hydrologic Loading with GPS 
Missoula Montana, July 2022
Applications will open Mid March via the CUAHSI Website. 

Join hydrologists and geodesists in this workshop on the emerging discipline of hydrogeodesy: the measurement of the distribution and movement of water at Earth’s surface and near-surface using observations of Earth’s shape, orientation, and gravitational field. 

Hydrogeodesy is an interdisciplinary field and, as part of this workshop, participants will explore more traditional hydrologic observations alongside geodetic datasets. Participants will be introduced to geodetic observations and specifically focus on how Global Navigation Satellite System (GNSS) observations of Earth’s surface can be analyzed and incorporated with hydrologic observations.

CUAHSI offers many funding opportunities for students and researchers in the water sciences. While these awards and fellowships may be relatively small, the impact may be large.   



CUAHSI has recently begun creating short, two to three minute How To videos to help users understand HydroShare’s capabilities and get the most out of their experiences on HydroShare! Find the playlist here. 


Shell Day: The HydroShare resource receiving the most external clicks in January 2021 was Shell Day Data. From the resource abstract, “Shell Day was a single-day regional water monitoring event coordinating simultaneous coastal carbonate chemistry observations by 59 community science programs and 7 research institutions in the northeastern United States, in which 410 total alkalinity (TA) samples from 86 stations were collected.” This particular resource has been viewed almost 500 times, and the resource was accessed from external sources (external to HydroShare) more than 100 times. It is gratifying that the coastal water-resources community are finding HydroShare to be a useful repository, and so many others are finding their way to HydroShare. 


In this release we focused on addressing bugs and implement system reliability improvements:
  • Fixed critical issue when deleting collections
  • Fixed several issue related to uploading, naming and selecting profile pictures and documents
  • Fixed the web app connector to allow deletion of resource icons
  • Improved rendering of long resource names 
  • Fixed additional issues related to references and versioning
  • Updated terms to express relationships between resources
  • Fixed issue to correct behavior when copying aggregations
  • Corrected functionality to not allow duplicate author names.
For more detail on this and previous releases, please check here.
