The role of larval supply in structuring marine communities is a hot topic in marine ecology. Researchers have investigated so-called "supply side ecology" or the "bottom up effects" of larval supply and have attempted to relate the rate of larval supply or recruitment to a population to currents that carry larvae away from or to settlement sites. Coastal upwelling and downwelling are a particular focus of these studies. In this SGER, investigators will test the hypothesis that the larvae of coastal barnacles are carried offshore by upwelling and shoreward by downwelling. Vertically stratified zooplankton samples and physical oceanographic data that resolve the cross-shelf oceanographic structure and larval distribution will be collected along a transect of stations off southern Oregon. The investigators predict that the larvae will behave like passive particles. Passive particles remain with a water mass and, hence, the distribution of passive-larvae should significantly correlate with water mass physical characteristics (e.g., salinity and temperature). The distribution of nonpassive- larvae, if they move between water masses, should not be correlated with a water mass' physical characteristics. The hypothesis that upwelling and downwelling affect distributions of larval barnacles and meroplankton is so central to current thinking in benthic ecology that a clear test of the hypothesis, no matter the outcome, will be of great interest and utility to the science. Broader impacts include participation of students at all levels by combining with an active award by Shanks in the NSF Science, Technology, Engineering, and Math (STEM) program. Research and observations will be shared with local commercial fishing community through the Scientists and Fisherman Exchange (SAFE) program. In addition, research results will be included in the process of establishing the marine reserve system in Oregon.

幼体供给在构建海洋群落中的作用是海洋生态学的一个热点问题。研究人员调查了所谓的“供应方生态学”或幼虫供应的“自下而上的效应”，并试图将幼虫供应或补充到种群的速度与将幼虫带离或带到定居点的水流联系起来。沿海上升流和下降流是这些研究的一个特别重点。在这个SGER中，调查人员将测试沿海藤壶的幼虫被上升流带到离岸和被下降流带到岸上的假设。将沿俄勒冈州南部外的一个样带沿着收集垂直分层的浮游动物样本和物理海洋学数据，以确定跨大陆架海洋学结构和幼虫分布。 研究人员预测，幼虫的行为将像被动粒子。被动颗粒保留在水团中，因此，被动幼虫的分布应与水团的物理特性（例如，盐度和温度）。非被动幼虫的分布，如果他们在水团之间移动，不应该与水团的物理特性相关。 上升流和下降流影响幼体藤壶和meroplankton的分布的假设是如此中心的海底生态学的当前思想，一个明确的测试的假设，无论结果如何，将是极大的兴趣和实用的科学。更广泛的影响包括各级学生的参与，结合在NSF科学，技术，工程和数学（STEM）计划中的Shanks积极奖。 研究和观察结果将通过科学家和渔民交流（SAFE）计划与当地商业渔业社区分享。 此外，研究成果将被纳入俄勒冈州建立海洋保护区制度的过程中。
