Kinnvika / Vestfonna 2009 Expeditions

by Veijo Pohjola and KINNVIKA members

The 2009 Kinnvika / Vestfonna expeditions comprised totally 39 individuals that spent 439 man-days in Kinnvika, during two spring/winter legs and three summer legs. Five persons joined both spring and summer operations. Transportation was provided by helicopter flights, 11 flights by Airlift, and 6 flights by the Norwegian Coast Guard from KV Svalbard. Ships used for transport were KV Svalbard, RV Horyzont and MS Farm. Weather crippled the first spring leg to only 3 long workdays on Vestfonna, while all other legs had better weather conditions.

Spring Operations

The spring operations were initially planned into three different legs, 1. A snowmobile mechanic team, with aim to set the machinery in Kinnvika into operable function, 2. A first science leg comprising Finnish-Swedish-US teams, and 3. A German-Polish team. The plan to best utilize the snowmachine park of Kinnvika consisting of 11 more or less maneuverable vehicles after the rough 2008 campaign was found best to be satisfied by spreading the teams into different legs.

Summer Operations

The summer expeditions comprised totally 29 individuals, in three legs. The first leg of German and US glaciologists/climatologists was flown in by Airlift 4th August to Kinnvika with a task to empty the data from their instruments. Their initial plan was to fly to the depot at Donckerfjellet, but fog over Nordaustlandet called the extension to Doncker off.

Report from Snow and Ice Studies on Kinnvika spring 2009 field campaign

Emilie Beaudon – PhD student – Arctic Centre, University of Lapland
(April 14th – May 19th)

mittausasema.jpg

Participants on the spring 2009 field campaign:

 

  • Emilie Beaudon, Arctic Centre, Rovaniemi
  • Bob McNabb, University of Alaska, Fairbanks
  • Dr Rickard Pettersson, Uppsala University
  • Pr Veijo Pohjola, Uppsala University
  • Dr Denis Samyn, Uppsala University

Associated colleague: Pr John Moore, Arctic Centre, Rovaniemi

Objectives:

Investigate the spatial and temporal variability of snow and ice chemical properties on Vestfonna. The results will be linked to meteorological studies performed during the IPY:

  • to find the airsnow transfer functions for interpreting information from future deep ice cores
  • to understand the local atmospheric circulation patterns

Field work 2009:

  • Drilling 15 m long firn core at summit Ahlmann (Kovacs drill)
  • Digging 3 snow pits on Vestfonna (snow stratigraphy, sampling for ions measurements, snow density)
  • Digging 1 snow pit on a frozen lake near Kinnvika station
  • Sampling surface snow at Ahlmann and Northern summits during an exceptional atmospheric event (Arctic Haze?)

The Paleontology Team Summer 2009

paleontologit ja luuranko.jpgParticipants: Svend Stouge, Lars Holmer and Jørgen Løye Christiansen

Purpose of trip:  to investigate and establish the stratigraphy of the exposed lower Palaeozoic sediments in Murchisonfjorden, Nordaustlandet.

Background: The Lower Palaeozoic sediments exposed in Murchisonfjorden on Svalbard are practically unknown and - until now - have been referred to the Krossøya and Sparreneset units, respectively considered as Cambrian and Ordovician in age.

Time-lapse Camera Team Report, Kinnvika 2009

by Bob McNabb, University of Alaska Fairbanks

Introduction

The goal of this expedition was to install two time-lapse cameras near the terminus of Franklinbreen, Vestfonna. The images from the cameras will provide a record of calving at Franklinbreen for the summer, and will be used to obtain terminus position, ice velocity, and calving fluxes. Bob McNabb of the University of Alaska, Fairbanks (UAF) was the only member of the camera team present at Kinnvika. Veijo Pohjola, Rickard Pettersson of Uppsala University, Sweden assisted in installing the camera boxes.

Cameras

The cameras are Canon EOS 40D with fixed 28mm lenses, attached to a timer set to take a photograph every 30 minutes. The boxes are mounted on top of surveying tripods, which are secured with rock cairns to prevent them from tipping over in high winds. Camera A is located at 80.091N, 019.195E, elevation 113 m. Camera B is located at 80.073N, 019.255E, elevation 37 m. The 32GB flash cards will be switched out at the end of the summer, when Regine Hock of the Geophysical Institute, UAF will visit Svalbard.
