As Alaska’s billion lakes become colder and harder, some of them will sport mysterious, spidery cracks extending from small holes in the ice. This phenomenon inspired a geophysicist to figure out what he calls “lake stars.” 
Last week, Carl Benson, 85, accepted a lifetime achievement award from the place he has worked since Dwight Eisenhower was president. As the snow and ice scientist and professor emeritus at University of Alaska Fairbanks’ Geophysical Institute rose to applause from his friends and coworkers, memories rushed back to me.
High-school dropout Austin Post’s career began in the 1950s, when colleagues made up the title “Senior Meteorologist” to include him in a funding proposal.
SAN FRANCISCO — Northern sea ice is at its lowest summer coverage since we’ve been able to see it from satellites. Greenland experienced its warmest summer in 170 years. Eight of 10 permafrost-monitoring sites in northern Alaska recorded their highest temperatures; the other two tied record highs.
Kenji Yoshikawa will soon sleep on brilliant, blue-white landscape that has never felt the imprint of his boots. Beginning on spring equinox, the permafrost scientist and a partner will attempt to drive snowmachines from Prudhoe Bay to Canada’s Baffin Island.
On the 5-mile snowmachine ride up to Point Barrow, we saw several fresh polar bear tracks the size of dinner plates, a pile of whalebones from last year, and a 3-foot-wide crack in the sea ice that could swallow a sled. The crack was created when an ice floe in the open water crashed into shore-fast ice.
The trick to getting a good ice core is to drill straight down into the sea ice, continually clear the slush gurgling up from the ocean, correctly reassemble the core fragments on the tray, take its temperature every couple of inches before it melts or cools, and saw it into hockey-puck-sized chunks without dropping them in the snow.
Every summer, Alaska’s glaciers melt and send vast quantities of water gushing through silty gray rivers, past towns and villages and finally into the sea. Some glaciers calve directly into the ocean, instantly losing car-sized chunks of ice and wowing boats full of tourists.
A time capsule of satellite imagery of the earth will become available to scientists this month.
A few months ago, I wrote about adventurer/permafrost scientist Kenji Yoshikawa’s attempt to drive a snowmachine 3,500 miles from Prudhoe Bay to the Atlantic Ocean. He planned to stop along the way to visit students in 13 villages. Near their schools, he wanted to drill holes in the ground and see how cold it is.
