NSF Sponsored Workshop Agenda Day 1: Scientific Questions and Measurements Required for Arctic Studies Location: Clark Laboratory, room 507; registration 9:30-10:00AM, workshop begins at 10:00AM On the first day, the environmental parameters that must be acquired will be defined. Key presentations will summarize the science motivation for various types of measurements in different disciplines, including physical and biogeochemical oceanography, ice physics and dynamics, and meteorological data and justify the urgent need for an observing system development. Day 2: Engineering solutions (methods and sensors) Location: Carriage House; registration/coffee 8:00-8:30AM, workshop resumes at 8:30AM After reviewing, and based on the scientific variables and sensors identified the previous day, the objective of the second day of the workshop is to design specific ice-tethered technology platforms. Workshop participants will be provided with the opportunity to give short presentations on their particular technological interests. Afterwards, working groups will establish specifications for various platforms, including expendable, non-expendable and shelf or seasonal ice zone (SIZ) systems. For example, sensors that are relatively inexpensive and with low power consumption may be appropriate for either expendable or non-expendable systems, while systems that incorporate expensive sensors or sample collectors will need to be recovered. Furthermore, distinct technological challenges must be considered for platforms intended for the shelf and SIZ regions. In practice, an array of ice-tethered platforms may consist of a mix of these different systems. Day 3: Implementation procedures and plans Location: Clark Laboratory, room 507; registration/coffee 8:00-8:30AM, workshop resumes at 8:30AM After reviewing, and based on the technology platforms specified the previous day, the objective of the third day of the workshop is to discuss implementation of an array of ice-tethered platforms to observe the Arctic. The numbers and types of platforms to thoroughly encompass the ice pack of the Arctic Ocean need to be defined, as does the rate at which systems must be replaced. Logistical concerns need to be considered, and a strawman program produced in order to provide a working estimate of the costs of developing and maintaining an ice-tethered observatory in the Arctic.
