Acadian Seaplants Limited (ASL) is an internationally recognized leader in the marine plant product industry.Based in Nova Scotia, ASL harvests the seaweed (rockweed) from intertidal areas on the Atlantic and Bay ofFundy coasts. ASL currently sells their products in more than 70 countries, creating close to 600 jobs in theMaritimes and bringing more than $40 M to the local economy. ASL is dedicated to running a responsible,sustainable, seaweed industry and as such has a long history of conducting research to determine best practices.To ensure proper management of this renewable resource, they monitor harvesting and growth along its leasedcoastlines. Currently, this task is executed using ground transects and accurate recording of harvests, thoughthis process is labour intensive and biased to more accessible coastlines. The use of satellite remote sensing tomap the seaweed relies on data acquired at low tide when the seaweed is exposed and no clouds or fog present,thus limiting acquisition time periods. Nova Scotia Community College's Applied Geomatics Research Group(AGRG) will explore a new remote sensing technology - airborne topographic-bathymetric lidar - to assist ASLin new and innovative mapping and monitoring of the rockweed resource. Specifically, AGRG will acquiremulti-year topographic-bathymetric lidar datasets for a section of ASL leased coastline in Southwest NovaScotia at low and high tide, immediately post-harvest, and one year post-harvest to determine resourceassessment, harvested biomass, and growth rates, respectively. NSCC's new sensor potentially eliminates therequirement for low tide acquisition to obtain measurements of seaweed. In addition, a hydrodynamic modelfor the site will be run to investigate current speeds and other dynamic features that may influence any growthrate variance within the site. The results from this innovative study will assist ASL to more efficiently monitorpresent resources and more precisely assess resources in new areas, and help ASL move to a more spatiallyintegrated workflow. The Nova Scotia Department of Fisheries and Aquaculture is responsible for permittingthe leases and ensuring the harvest operations are sustainable, and are financially supporting the project.

阿卡迪亚水上乐队有限公司（ASL）是海洋植物产品行业的国际认可的领导者。基于新斯科舍省，ASL从大西洋和湾境海岸的潮流地区收获海藻（Rockweed）。 ASL目前在70多个国家 /地区出售其产品，在Temaritime中创造了近600个就业机会，并为当地经济带来了40多美元。 ASL致力于运营一个负责任的，可持续的海藻行业，因此有悠久的研究历史来确定最佳实践。为了确保对这种可再生资源的适当管理，他们监测了沿其租赁海岸线的收获和增长。目前，该任务是使用地面样本和精确记录收获执行的，尽管该过程是劳动密集型的，并且对更可访问的海岸线有偏见。卫星遥感的使用tomap tomap海藻依赖于海藻暴露时在退潮时获得的数据，而没有云或雾存在，从而限制了获取时间。新斯科舍省社区学院的应用地理研究小组（AGRG）将探索一种新的遥感技术 - 机载的地形 - 伴随 - 伴随型激光雷达 - 以协助Aslin新的，创新的岩石资源映射和监视。具体而言，AGRG将在低潮和高潮后，在新诺华西南部的ASL租赁海岸线，收获后立即获得ASL租赁的海岸线，并在收获后立即获得ASL租赁的海岸线，并分别确定资源审查，收获的生物质和增长率。 NSCC的新传感器有可能消除潮汐采集的资格，以获得海藻的测量。此外，将运行的流体动力模态将调查当前速度和其他动态特征，这些速度可能会影响站点内的任何成长差异。这项创新研究的结果将有助于ASL更有效地监控陈述资源，并更精确地评​​估新领域的资源，并帮助ASL转向更空间整合的工作流程。新斯科舍省渔业和水产养殖部负责允许租赁并确保收获业务可持续，并在财务上支持该项目。
