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 of Fundy coasts. ASL currently sells their products in more than 70 countries, creating close to 600 jobs in the Maritimes 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 leased coastlines. Currently, this task is executed using ground transects and accurate recording of harvests, though this process is labour intensive and biased to more accessible coastlines. The use of satellite remote sensing to map 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 ASL in new and innovative mapping and monitoring of the rockweed resource. Specifically, AGRG will acquire multi-year topographic-bathymetric lidar datasets for a section of ASL leased coastline in Southwest Nova Scotia at low and high tide, immediately post-harvest, and one year post-harvest to determine resource assessment, harvested biomass, and growth rates, respectively. NSCC's new sensor potentially eliminates the requirement for low tide acquisition to obtain measurements of seaweed. In addition, a hydrodynamic model for the site will be run to investigate current speeds and other dynamic features that may influence any growth rate variance within the site. The results from this innovative study will assist ASL to more efficiently monitor present resources and more precisely assess resources in new areas, and help ASL move to a more spatially integrated workflow. The Nova Scotia Department of Fisheries and Aquaculture is responsible for permitting the leases and ensuring the harvest operations are sustainable, and are financially supporting the project.

Acadian Sapplants Limited（ASL）是海洋植物产品行业的国际公认领导者。 ASL总部位于新斯科舍省，从大西洋和湾的潮汐地区收获海藻（岩菜） 有趣的海岸。 ASL目前在70多个国家 /地区出售其产品，在该公司中创造了近600个工作岗位 海事并为当地经济带来了40多美元以上。 ASL致力于运行负责任， 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。 为了确保对该可再生资源的适当管理，他们监视租赁的收获和增长 海岸线。当前，该任务是使用地面样带和精确记录收获执行的，但是 这个过程是劳动密集型的，并偏向于更容易获得的海岸线。卫星遥感的使用 地图海藻依赖于海藻暴露而没有云或雾时在潮汐处获得的数据， 因此限制了获取时间。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 - 机载地形 - 触觉激光雷达 - 以协助ASL 在新的和创新的映射和对冰草资源的监视中。具体而言，AGRG将获得 西南Nova的一部分ASL租赁海岸线的多年地形 - 干扰激光雷达数据集 涨潮和高潮时的斯科舍省，收获后立即在收获后一年，以确定资源 评估，收获的生物量和增长率分别。 NSCC的新传感器有可能消除 要求涨潮的要求以获得海藻的测量。另外，流体动力模型 对于该站点，将运行以调查可能影响任何增长的当前速度和其他动态特征 网站内的速率差异。这项创新研究的结果将有助于ASL更有效地监视 呈现资源，更精确地评​​估新领域的资源，并帮助ASL转向更空间 集成工作流程。新斯科舍省渔业和水产养殖部负责允许 租赁和确保收获业务的可持续性，并在财务上支持该项目。
