Aims:
  1. Determine the time course and magnitude of changes in vitamin D status during wintering over in Antarctica, with or without vitamin D supplementation.
  2. Determine other markers of bone and calcium metabolism (such as serum calcium, 1,25-dihydroxyvitamin D, parathyroid hormone) before and after vitamin D supplementation to determine the effectiveness of supplementation.
  3. Determine the relationships between vitamin D status and immune response. A polymerase chain reaction assay will be used to determine the reactivation patterns of varicella-zoster virus, a causative agent of chickenpox in children and shingles in adults.  Salivary cortisol, a stress hormone, will also be quantified.
