A network of data loggers and sediment traps was deployed by researchers for the University of Arizona in three lakes on three islands to monitor meteorological, limnological, and sedimentation variability as a function of climate changes in the region. The dominant interannual variability is caused by ENSO and during the period of deployment the region exhibited a minor El Nino (2009-2010) followed by modest La Nina conditions (2010-2011). The region is now in a neutral state with predictions of an El Nino beginning again in winter 2012-2013. The data loggers are filled to capacity and need to be retrieved, downloaded and replaced. In addition sediment traps contain the particle rain related to the transition from the week/moderate El Nino to the 2010 La Nina. Replacement with new traps will permit observations of the transition back into El Nino conditions.This project will support the research of two early career scientists: Jessica Conroy, an NSF Postdoctoral Fellow now at Georgia Tech, and Diane Thompson, an advanced graduate student from the University of Arizona.This an excellent proposal for RAPID funding because: 1) the data collection systems are full and should be replaced this fall before the onset of the next El Nino: 2) the sediment traps will have a record of the most recent La Nina and immediate research progress will occur by retrieving and processing these samples; 3) two early career scientists have studies underway (begun during their Ph.D. thesis research) which will benefit greatly from this field program; 4) the redeployment of new monitors will be in place prior to the beginning of the next El Nino.

亚利桑那大学的研究人员在三个岛屿的三个湖泊中部署了一个数据记录器和沉积物收集器网络，以监测该地区气候变化函数的气象、湖泊学和沉积物变化。 主要的年际变化是由 ENSO 引起的，在部署期间，该地区出现了轻微的厄尔尼诺现象（2009-2010 年），随后出现了温和的拉尼娜现象（2010-2011 年）。 该地区目前处于中性状态，预计厄尔尼诺现象将在 2012-2013 年冬季再次出现。 数据记录器已满，需要检索、下载和更换。 此外，沉积物捕集器还包含与从周/中度厄尔尼诺现象到 2010 年拉尼娜现象过渡相关的颗粒雨。 更换新的陷阱将允许观察回到厄尔尼诺条件的转变。该项目将支持两位早期职业科学家的研究：杰西卡·康罗伊（Jessica Conroy），美国国家科学基金会博士后研究员，现就职于佐治亚理工学院，黛安·汤普森（Diane Thompson），亚利桑那大学的高级研究生。这是快速资助的一个极好的建议，因为：1）数据收集系统已满，应在今年秋天下一次厄尔尼诺现象爆发之前更换。 尼诺：2）沉积物收集器将记录最近的拉尼娜现象，通过检索和处理这些样本将立即取得研究进展； 3) 两名早期职业科学家正在进行研究（在他们的博士论文研究期间开始），他们将从该实地项目中受益匪浅； 4) 新监测员的重新部署将在下一次厄尔尼诺现象开始之前到位。
