Last week, scientists and staff from the Alaska and Pacific Islands Climate Adaptation Science Centers (CASCs) gathered in Juneau, Alaska to foster cross-CASC collaborations.

Check out the following National Science Foundation Programs for graduate students to work with USGS researchers. 

Two NSF programs—GRIP and INTERN—fund opportunities for graduate students to work for the USGS.

The objectives of the programs are:

1. to provide professional growth opportunities for the students by providing them with new mentors, techniques, or ideas that are not available to them at their home institutions; and

The Northwest Climate Conference will be in Portland, Oregon from October 8-10th.

Are you attending the Northwest Climate Conference in Portland, Oregon? If so, check out these presentations from the Alaska Climate Adaptation Science Center. On October 8th-10th, the conference will bring together practitioners, scientists, tribal communities, and decision-makers to share knowledge, ideas, and best practices related to climate change science, impacts, and adaptation in the Pacific Northwest. Topics include drought, wildfire, extreme events, coastal flooding, human and ecosystem health, and resiliency planning.

Be it flowing in rivers or glaciers, falling as snow, or carving the coast in waves, Southeast Alaska is a landscape shaped by water.

Update 07/27/2018

We were up in the basin on Monday and Tuesday to survey points, fly the drone and recover some of our instruments. Unfortunately, the two backup gages are covered by several meters of ice. We still hope to get them back by the end of the season. There is a lot of ice perched high up in the basin, probably related to the disintegration of the floating tongue, which produced a lot of freely moving ice.

Site visit 07/17/2018

We visited Suicide Basin earlier tonight (4:00 until 7:30 pm). The water flow over the dam diminished during that time while the water level in the lake started dropping noticeably. The drop is also visible in the timelapse feature tracking.

Site flyover 07/16/2018

Suicide Basin started spilling over this morning and the water elevation appears to have reached temporary steady state between 3:00 and 6:00 pm today.

We flew over the site this afternoon. Some of my photos below. Water level according to our imagery was at ~442 m, about 0.5 m higher than the lowest point in the dam.

Fig. 1. Orthoimage from 07/12/2018 including elevation contours. Lake level at 5:50 pm was approximately 438.5 m The lowest point of the dam has an elevation of 441.5 m.

Water level at 5:50 pm: ~438.5 m

Water level increase 3:30 pm – 5:50 pm: 9 cm (equivalent to 0.93 m / day)

Lowest point of dam: ~ 441.5 m

As of last night, there was a 3 m difference between the water level elevation and the elevation of the lowest point of the dam (Figures 1, 2). At the current rate of water level increase, the lake would start spilling over between Sunday evening and Monday morning. While the water level increase slowed down last night (cold, no rain), warm temperatures today and rain on Saturday/Sunday may reverse this trend again.

Climate science is a complex and often misinterpreted field. This week a group of climate scientists came together in Fairbanks to address this issue.

Research Highlight

Berries are extremely important to human and wildlife communities in Alaska, and in some locations abundance has decreased significantly in recent years.
