IPS冰剖面儀在短周期海浪在北極浮冰中傳播的衰減和反射研究中的應(yīng)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：
介紹增加區(qū)域波浪能的潛力（Thomson&Rogers，2014），這直接影響了剩余的海冰覆蓋。海冰的波傳播穿透力隨著波周期和波長的增加而增加（Squire等人，2009），導(dǎo)致彎曲斷裂和冰蓋破裂（Wadhams等人，1988；Asplin等人，2012；Collins等人，2015）。這些變化迅速增加了邊緣冰區(qū)（MIZ）的大小（Collins等人，2015），較小的、可移動(dòng)的浮冰更容易受到橫向融化和動(dòng)態(tài)強(qiáng)迫的影響（例如Splash等人，2014）。因此，冰中波浪（WII）事件在海冰建模界引起了極大的興趣。
