Trees among the tundra

TOOLIK LAKE STATION, ALASKA-- Balsam poplar is the northern-most tree species in North America. In Arctic Alaska, it occurs sporadically in isolated stands often adjacent to perennial springs or on south-facing slopes. Join our field crew as we venture... {Read More »}



The Home Stretch

COLVILLE RIVER, ALASKA– The science has reached the home stretch now, as has the entire summer’s field effort. We got a break in the cloudy weather last night, and sat around a fire labeling sample bags and weighing/organizing samples... {Read More »}



“Here Comes the Rain Again”

COLVILLE RIVER, ALASKA-- We awoke this morning to rain, wind, and 35? F temperatures. Immediately the remaining sampling lost most of its appeal, but we inhaled our coffee and oatmeal and staggered forth through the wet brush and tussock tundra... {Read More »}



Massive Permafrost Exposure

COLVILLE RIVER, ALASKA– Days drift by on the river. The wind of the previous entry indeed subsided that evening, and we paddled from 11 PM to 5 AM, stopping for an hour to gape in awe at a massive exposure of permafrost (frozen ground) towering above the river... {Read More »}



“Out in the Cold Rain and Snow”

COLVILLE RIVER, ALASKA– Finally, there is time to journal, as we are still relaxing in the “Salix Lounge” (Latin genus for willow). We’ve spent 36 hours watching the river flow backward – upriver. It has granted us time to catch up on some of the scientific literature, so we’ve been discussing the changes underway in North Slope river floodplains... {Read More »}



Against the Wind…We Were Paddlin’ Against the Wind

COLVILLE RIVER, ALASKA-- Aha! Windstorm #2, and we have ducked into some willows after the wind halted our downriver progress. This morning was crisp and clear, but the wind produced swells and breaking waves moving upriver... {Read More »}



Alpine Tundra Yielding to Shrubs

COLVILLE RIVER, ALASKA-- Another day of fieldwork and floating later, we are camped on a big bend in the Colville, across from cliffs and peregrine falcons. Yesterday saw more science, including clear evidence of shrubs colonizing alpine tundra... {Read More »}



Science Underway in the Tundra

COLVILLE RIVER, ALASKA-- The four-person crew for this second float of the summer is led by Greta Myerchin and myself, both veterans of the first trip (Nimiuktuk/Noatak) and familiar with the science and wilderness protocols... {Read More »}



Trucks on the Tundra

TOOLIK FIELD STATION, ALASKA-- The field station maintains a small fleet of trucks to access field sites adjacent to the nearby Dalton Highway. These trucks… {Read More »}



Into the Wilderness, Part Deux

COLVILLE RIVER, ALASKA-- Welcome back and thanks for tuning in for the second science adventure of the summer. Scientifically, the premise and protocol on this trip is similar to the first trip, but this one is considerably longer – 18 days instead of 12 – and further north... {Read More »}
