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.

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.
