2003 Polar Marine Science Gordon Conference

Storm 0236146该奖项是对第四届戈登极地海洋科学研究会议与会者的旅行和注册费用的支持。会议定于2003年3月16日至21日在加利福尼亚州文图拉举行，将讨论“变化中的极地海洋：变化中的气候对物理、化学、生物和耦合系统的影响”这一主题。会议将评估最近记录的影响北方和南方极地海洋系统的大规模年际变化、其物理基础及其对物理、化学、生物和耦合系统的影响。将变化定性为振荡、突变或长期趋势将是随后讨论的核心。将讨论物理变化对上层海洋生物地球化学系统的影响，例如涉及溶解氧吸收和二氧化碳分压平衡的影响，以及对底栖-中上层耦合和碳收支的影响。使用硅藻和棕囊藻的生物标志物将在年际变化的背景下进行讨论。将审议气候变化对海冰覆盖的影响，以及对冰生物区系和对二氧化碳和二甲基硫等物质交换的可能后果。将试图评估更广泛的食物网变异性的同时年际变化的各个方面。现场和模拟结果以及过去条件的古海洋学重建将用于讨论。

Storm0236146This award is a contribution toward support of travel and registration costs for participants in the Fourth Gordon Research Conference on Polar Marine Science. The conference, scheduled to take place on 16-21 March 2003 in Ventura, CA and will address the topic of The Changing Polar Oceans: Impacts of a Changing Climate on Physical, Chemical, Biological and Coupled Systems. The conference will assess the recently documented large-scale, interannual changes that have impacted the northern and southern polar ocean systems, their physical bases, and their impacts on physical, chemical, biological and coupled systems. Characterization of changes as oscillations, abrupt shifts or long-term trends will be central to subsequent discussion. Impacts of the physical changes on upper ocean biogeochemical systems, such as those involving dissolved oxygen uptake and the pCO2 balance, will be addressed, as will impacts on benthic-pelagic coupling and the carbon budget. Use of biological markers from diatoms and Phaeocystis will be discussed within an interannual change context. Impacts of the changing climate on sea ice cover, and likely consequences to ice biota and to the exchange of such substances as CO2 and DMS, will be considered. An attempt will be made to assess aspects of concurrent interannual changes in broader food web variability. Both field and modeling results and paleoceanographic reconstruction of past conditions will be used in the discussions.
