Sub-bottom Profiling System (SBPS) for Advancing Research in Environmental Change from Remote Lakes

该提案要求54,960美元的资金用于购买一个底层分析系统（SBPS），该系统将由女王大学生物系古生态环境评估与研究实验室（PEARL）和地理系环境变化与极端实验室（EVEX）的科学家使用。海底剖面系统利用声波来探测由声阻抗变化引起的不同特征沉积物的地层差异。由于SBPS在不影响分辨率的情况下体积更小、重量更轻，现在可以从偏远的小湖泊中生成沉积结构的常规数字剖面。此外，专门研究小型偏远湖泊的科学家现在也可以从事那些在较老较重的SBPS上根本不可能完成的项目。PEARL和EVEX实验室认识到便携式SBPS为我们各自的研究带来了巨大的研究机会。此外，关于使用SBPS的培训将加强对毕业生的培训，从而促进新发现，并提高他们在先进地理空间技术和分析方面的能力。

This proposal requests funding in the amount of $54,960 to purchase a Sub-bottom Profiling System (SBPS) that will be used by scientists at the Paleoecological Environmental Assessment and Research Laboratory (PEARL) in the Department of Biology at Queen's University, and the Environmental Variability and Extremes Laboratory (EVEX) in the Dept. of Geography. Sub-bottom profiling systems use acoustic waves to detect stratigraphic differences in sediments of varying characteristics that result from changes in acoustic impedance. Routine digital profiles of sedimentary structure can now be generated from small remote lakes due to advances that have made SBPS significantly smaller and lighter, without compromising resolution. Additionally, scientists specializing in small remote lakes can now also pursue projects that simply weren't possible with the older heavier SBPS. The PEARL and EVEX labs recognize the tremendous research opportunities that portable SBPS bring to our respective research. Additionally, training on the use of the SBPS will enhance the training of our graduates that will promote new discovery and will enhance their abilities in advanced geo-spatial techniques and analyses.
