Description
Summary:During last year, the Northwest Research Associates Arctic team completed the Spring SIMI field program in the Beaufort Sea. We have subsequently conducted data analysis and written papers on that data. In addition, we organized the Ice Mechanics and Arctic Modeling Workshop to be held in Anchorage, AK, April 25-28, 1995, which will report on the research findings of SIMI and will also address future research needs. During this year, we presented a paper on Sea Ice Mechanics Initiative (SIMI) at the Offshore Technology Conference in Houston, TX, in May 1994. The presentation was an attempt to foster communication between the Arctic research being done at the Office of Naval Research and the Arctic offshore-work of the oil industry. The findings of our SIMI field work are reported in our paper entitled Sea Ice Mechanics Research, which appears in Volume I of the Sea Ice Mechanics and Arctic Modeling Workshop proceedings. We have written a paper entitled Forced-Displacement Measurements of a First-year Pressure Ridge and Keel to be presented at Sea Ice Mechanics '95 Symposium as part of the ASME Joint Applied Mechanics and Materials summer meeting at UCLA in June 1995. The results from this data analysis show that the strength of partially consolidated ridges changes in a period of two weeks from an active component in sea ice dynamics to an inactive component, because of its strength. We participated in the preparation of a second paper for the Ice Mechanics '95 Symposium with Dr. R. S. Pritchard of IceCasting and with Drs. D. M. Farmer and Y. Xie of Institute of Ocean Sciences.
