Due to high winds and low visibility on the ice sheet, a scheduled flight to Summit Station, Greenland, has been cancelled today. The flight would have brought additional personnel and supplies to the outpost to prepare for the busy summer research period. An advance team arrived on Thursday and has begun turnover with the staff of five who have been maintaining ongoing experiments since early November.

Saturday’s forecast calls for improving conditions, though continued high winds may keep the staff grounded in Kangerlussuaq for another day. Stay tuned.

A Norland Air Twin Otter plane on skis landed at Summit Station today, delivering staff, materials, and fresh fruit and vegetables. A staff of five, isolated at the station since early November, welcomed the advance team to the remote research outpost on Greenland’s icesheet.  It’s “a full Big House,” commented station manager Ben Toth, referring to Summit Station’s iconic main building. “It’s nice to have some new faces around.”

The Twin Otter paused only long enough to deliver passengers and cargo before flying on to Kangerlussuaq on Greenland’s west coast. Additional CPS staff are waiting there to assist with Summit’s transition and/or staff the station until it opens for the summer research period in April. Weather permitting, the Twin Otter will fly this team to Summit tomorrow before flying back to Iceland.

What light through yonder window breaks?

Our friends at Summit Station welcomed the sun yesterday. “I could almost even feel its warmth on my face…. almost,” wrote station manager Ben Toth.

The sun is returning, and so is a small plane, which should approach the station via Iceland tomorrow. It will drop off fresh veggies and an advance team of staff, then fly to Kangerlussuaq to pick up the remaining staff waiting to get in to Summit.  It’s time for a fresh crew to prepare for the busy research season ahead.

So far, the forecast is favorable, so cross your fingers. Meanwhile, here’s another picture of the dawn.

A late December bedecking of Yukimarimo around Summit Station seemed like “a present befitting the season,” wrote Ben Toth, whose team is keeping the NSF-funded research station and its ongoing experiments running through mid-winter.

“These little snowballs occur when fine frost layers form on the snow surface at cold air temperatures,” Ben explained. “These balls form due to weak wind conditions and become mobile, like little tumbleweeds across the surface, collecting in pockets sculpted by drift or in footprints.”

Ben says the team of five “finished off the year with a productive week sandwiched between the two holidays. Christmas Sunday was celebrated with the requisite Christmas tunes, a lit tree, decorations, and a Kiwi-style meal of “good tucker.” Rack of lamb and pavlova was on the menu as was roasted squash (the very last) and amazing maple syrup pies.

“New Year’s Eve was celebrated [with] a plethora of appetizers. . . . The tapas-themed meal segued into a comfortable evening counting down to 2012. All hands made it to midnight but retired shortly thereafter, rising somewhat later than usual on New Year’s Day to spectacular light and clear weather bringing in the new year.”

 Frosty Freeze

The walk back from the atmospheric watch building seems a bit longer on cold winter days. From this point of view, Summit Station's science and operations building nudges the iconic Big House, with its roof-perched radome and welcoming porch light. Photo: Shannon Coykendall

We were glad to read that cold north winds, which for several weeks had been dominating the weather reports from Summit Station, subsided last week. A welcome relief to deep freeze conditions reported earlier. “We hit a wind chill of -107F earlier today and the ambient temperature is around -67F…it doesn’t take much wind to make it bite!”, wrote Shannon Coykendall on 30 November.

In addition to bringing the cold, north winds can blow exhaust from station generators into the pristine sampling zone. Ongoing atmospheric and snow chemistry measurements are impacted when the station’s emissions mix into the signal. So, during periods when the winds blow from the north, station personnel avoid activities that create exhaust.

Twice during late November and early December, the staff had to fire heavy equipment to collect snow to resupply the station’s water supply during north wind conditions. Each time, the science technicians followed protocol and notified the research community.

Finally, last week, “Summit crawled out from underneath the north winds that have dominated the past few weeks. Bringing clouds and warmer weather, the southerlies created an opportune chance to catch up on making water and for the science techs to perform their non-north wind tasking,” wrote station manager Ben Toth. “The winds also gained strength this week, reaching sustained speeds of 15.5 knots. Temperatures this week ranged from a low of -60 C on Tuesday to a high of a balmy -34 C on Saturday.”–Kip Rithner
