Group: Summary

   The Sea Ice Experiment - Dynamic Nature of the Arctic (SEDNA) is an 
   international collaborative effort to improve the understanding of the 
   interaction between sea ice dynamics and Arctic climate. It was also the first 
   International Polar Year 2007-2008  field project.  

   The SEDNA data portal provides access to many and varied data sets from the 
   diverse set of campaign participants.  The data portal holds 37 entries from 
   remote sensing to in situ measurements collected during the ice camp in March 
   and April 2007. This data collection is distributed by the International 
   Arctic Research Center (IARC) at the University of Alaska Fairbanks (UAF). 
   NSIDC maintains the metadata for this data collection, so the data are easier 
   to find through the NSIDC data catalog and those catalogs with which NSIDC 
   shares metadata. This summary and metadata are accurate as of June 2011.  The 
   UAF archive site may have more recent data updates and publications, please 
   visit their site for the most up-to-date information.

   The mass balance of sea ice and the evolution of sea ice thickness 
   distribution is a key component of the Arctic system. It is controlled by 
   thermodynamic ice growth and melt, mechanical redistribution through ridging 
   and rafting, and transport. The SEDNA experiment was designed in a regional 
   Lagrangian frame of reference and tracked the evolution of a region of ice 
   surrounding the Applied Physics Laboratory Ice Station (APLIS) 2007 ice camp 
   in an effort to evaluate the role of mechanical redistribution on ice 
   thickness distribution. The SEDNA data collection is unique in that several 
   ice thickness data sets were inter-calibrated and coordinated with monitoring 
   of the ice pack strain-rate (horizontal deformation) and measurements of 
   internal ice stress. This experiment was designed to improve our understanding 
   of the relationship between sea ice thickness and dynamics and to investigate 
   the stress and strain-rate relationships with a comprehensive suite of 
   spatio-temporal coincident observations.

   Measurements were made with the aim of resolving the time evolving ice 
   thickness distribution in the vicinity of the ice camp, to map ice pack 
   deformation (strain-rate), and track strain-rate and internal ice stress in 
   time. This has required a detailed inter-comparison of ice thickness 
   measurements from a number of sources including submarine upward looking sonar 
   (ULS) (Peter Wadhams), AUV multi-beam ULS (Peter Wadhams and Martin Doble), 
   airborne LIDAR (Rene Forsberg), Helicopter borne electromagnetic induction 
   (EMI) (Christian Haas), and in situ snow and ice measurements with drill and 
   EM-31 soil surveyor (Cathy Geiger and Jackie Richter-Menge). Sea ice 
   deformation was mapped in near-real time from analysis of RADARSat-1 ScanSAR-B 
   by the Map of Moving Topography method (Mani Thomas, Chandra Kambhattmettu, 
   and Cathy Geiger), and high temporal sampling was achieved with an array of 
   GPS drifting buoys (Jenny Hutchings). Matt Pruis used GPS buoys to measure 
   deformation of single leads. Ice stress and mass balance were measured with 
   CRREL stress buoys (Jackie Richter-Menge). Additional measurements include a 
   3-m weather station (Andrew Roberts), CTD profiles every six hours (Jeremy 
   Wilkinson), downward looking Acoustic Doppler Current Profiler (ADCP), and 
   met-buoys (Ignatius Rigor). 

   Data are generally available in three formats: the original format, netCDF, 
   and ASCII. The original version is not always well documented.  The netCDF 
   version includes carefully collected documentation placed in the header fields 
   of the netCDF file. Often, data are also available in a separate ASCII file as 
   columns of data concatenated behind the netCDF header information in plain 
   text form.

   SEDNA is supported by the NSF Grant "Collaborative Research: Detailed 
   Investigation of the Dynamic Component of Sea Ice Mass Balance" (OPP ARC 
   0612527 (UAF), 0611991 (CRREL), and 0612105 (University of Delaware)).
