IPS冰剖面仪在短周期海浪在北极浮冰中传播的衰减和反射研究中的应用
Abstract
Dramatic reductions in sea ice extent (Parkinson, 2014), thickness and volume (Laxon et al., 2013), and increasing melt season length (Stroeve et al., 2014) have been observed in the northern hemisphere. Large expanses of open water (Walsh, 2013) and commensurate increases in fetch
introduce the potential for increasing regional wave energy (Thomson & Rogers, 2014) which directly impacts the remaining sea ice cover. Wave propagation penetration of sea ice increases with wave period and wavelength (Squire et al., 2009), inducing flexural fracture and ice cover break-up (Wadhams et al., 1988; Asplin et al., 2012; Collins et al., 2015). These changes rapidly increase the size of marginal ice zone (MIZ) (Collins et al., 2015), with smaller, mobile ice floes that are more susceptible to lateral melting and dynamic forcing (e.g.Asplin et al., 2014). Waves-in-ice (WII) events are, therefore, of great interest within the sea ice modeling community.
This poster presents an analysis of a waves-in-ice event 23 –24 May 2011 identified within data
collected during an extensive three-year program of oceanographic and ice measurements as part of the 2009 -2011 ArcticNet-Industrial Partnership Program in support of oil and gas exploration by Imperial Oil Ltd. (IOL) and BP Ltd.
摘要：
介绍增加区域波浪能的潜力（Thomson&Rogers，2014），这直接影响了剩余的海冰覆盖。海冰的波传播穿透力随着波周期和波长的增加而增加（Squire等人，2009），导致弯曲断裂和冰盖破裂（Wadhams等人，1988；Asplin等人，2012；Collins等人，2015）。这些变化迅速增加了边缘冰区（MIZ）的大小（Collins等人，2015），较小的、可移动的浮冰更容易受到横向融化和动态强迫的影响（例如Splash等人，2014）。因此，冰中波浪（WII）事件在海冰建模界引起了极大的兴趣。
本文展示了对2011年5月23日至24日在一个为期三年的海洋和冰测量广泛计划中收集的数据中发现的冰中波动事件的分析，该计划是2009-2011年ArcticNet-工业伙伴计划的一部分，以支持帝国石油有限公司（IOL）和英国石油有限公司的石油和天然气勘探。
