The Coordinated Eastern Arctic Experiment: SPRI sea-ice studies

Abstract

AbstractDuring March and April 1989 a two-man team from the Scott Polar Research Institute (SPRI) and Science Applications International Corporation (SAIC) took part in the oceanography ice camp phase of the Office of Naval Research-sponsored Coordinated Eastern Arctic Experiment (CEAREX). The aim of the experiment was to measure with strainmeters and tiltmeters the interaction between oceanic internal waves and sea ice. Arrays of these instruments were deployed to measure horizontal strain and vertical tilt fields continuously over a 29-day period. The resulting time series show quite clearly internal wavelike activity indicating that a strong coupling mechanism exists. Other interesting phenomena are evident in the data with timę-scales varying from seconds to several days.
