Amy Macpherson joins us as the SNAP and AK CASC Data Manager and Analyst. Macpherson will be assisting with assisting researchers with metadata creation and maintenance and in keeping data organized and accessible for all users.

We drilled in a new melt wire at the basin entrance (to continue the ice melt measurements we started last spring), deployed the drone (for DEMs and orthoimages), surveyed the lowest point in the dam (to constrain the maximum water level), and deployed additional air temperature sensors higher up in the basin (to facilitate melt modeling across the entire Suicide Basin watershed).

Using the drone-based elevations models from last year, we derived an approximate vertical scale for the rock face on the north side of the basin. This scale is plotted on top of the telemetered photos and gives an approximate idea about the ice/water elevation in the absence of telemetered water level measurements.

We installed the non-telemetered water level gauges, webcam, temperature and precipitation gauges, and the on-ice GPS. We also measured ice melt. We didn’t fly the drone and weren’t able to access/survey the water surface this time.

The term drought brings to mind cracked earth, forest fires, and empty river beds, but at the Southeast Alaska Drought Workshop held in Juneau this week, a different type of drought was discussed.

Last week, fourteen representatives from five tribes traveled to Fairbanks for a three-day knowledge-sharing workshop on a topic they are reckoning with daily: climate change.

Understanding the climatic conditions that influence wildfire patterns can improve our ability to predict the occurrence and severity of future wildfires.

Where does one start when tackling the thorny challenge of talking about climate change? AK CASC staff and researchers held an interactive seminar at the 2019 Alaska Forum on the Environment in Anchorage last week.

The AK CASC network will be presenting and moderating a number of sessions next week at the Alaska Forum on the Environment (AFE). AFE is a statewide gathering of government agencies, non-profit and for-profit businesses, community leaders, Alaskan youth, conservationists, researchers, and community elders, interested in Alaska's earth and environmental issues and challenges. This year is the 21st annual event, held in Anchorage. AK CASC staff, senior scientists, and affiliated researchers are involved in the following sessions.
