The fleet of corers we request is urgently needed to enhance and to replace, our ageing and broken or lost coring equipment that are deployed in the St. Lawrence and the Arctic. UQAR and its nonprofit organization, REFORMAR, manage research vessels for the Canadian scientific community (R/V Coriolis II, Lampsillis, Louis-Edmond-Hamelin,) which provides access to the St. Lawrence seaway. These ships are suitable for deploying the coring suite requested. In the Arctic, where most of the team members have NSERC-DG grants, the CCGS Amundsen is used for scientific research with the capacity to deploy the proposed corers. These research ships are the most (if not the only) cost-effective way for Canadian researchers to develop research projects requiring seafloor samples in the St. Lawrence and the Arctic. The ISMER-UQAR coring suite was used extensively over the past 20 years by the Canadian community. Most instruments now show signs of advanced wear and are becoming increasingly ineffective to collect sediments. Historically, in addition to the extensive use by ISMER-UQAR, the coring equipment was used for the research programs of several researchers from McGill, U. Laval, INRS-ETE, Concordia U. and UQAM, as well as by provincial and federal ministries (e.g., Fisheries and Oceans Canada, Geological Survey Canada, Environment Canada). From 2001-2021, the equipment was used by 437 researchers to recover samples for over 110 scientific expeditions at sea (842 days at sea) and used in the training of 1593 HQP. Now, our box corer, the most highly used of our corers for recent sediment and benthic fauna needs urgent replacement as it was lost at sea. Furthermore, we are lacking the means of sampling near the surface-water interface for benthic biology and biogeochemistry. We seek funding to diversify our coring suite including box corer, hammer corer, multi-corer and vibrocorer. The box, hammer and multi corer will provide enhanced and more precise access to samples from the sediment-water interface. The vibrocorer can penetrate consolidated or coarser sediments and thus allows us to access the sedimentary records of sandy or consolidated layers. The hammer corer is ideal for shallow water work aboard a small boat, which can lower operational costs. Together, this suite allows full integration of sediment sampling that opens the door to new projects and boosts innovation. We also request funds for a multi-corer, a vibrocorer and a small portable hammer corer. A large portion of Canadian oceanography research relies on this equipment in order to retrieve the sediments needed for geological, biological and geochemical oceanography in the Arctic and the St. Lawrence. To grant broad access to the equipment, we maintain a pool of instruments accessible by all Canadian researchers and readily available to any potential users. This guarantees that the equipment is available to all regardless of personal background.

迫切需要我们要求的旋转木船来增强和更换我们在圣劳伦斯和北极部署的衰老，破碎或丢失的加油设备。 UQAR及其非营利组织改革组织管理加拿大科学界的研究船（R/V Coriolis II，Lampsillis，Louis-Edmond-Hamelin，Louis-Edmond-Hamelin），可通往圣劳伦斯海道。这些船适用于部署请求的加油套件。在大多数团队成员获得NSERC-DG赠款的北极中，CCGS Amundsen用于科学研究，具有部署拟议的振动者的能力。这些研究船是加拿大研究人员开发需要在圣劳伦斯和北极地区开海底样品的研究项目的最具成本效益的方法。在过去的20年中，加拿大社区广泛使用了Ismer-Uqar Coring Suite。现在，大多数乐器都显示出高级磨损的迹象，并且越来越无效地收集沉积物。从历史上看，除了Ismer-Uqar的广泛使用外，Coring设备还用于麦吉尔，U。Laval，Inrs-Ete，Concordia U.和Uqam的几位研究人员的研究计划，以及省和联邦部门（例如，加拿大渔业和海洋，加拿大地质调查局，加拿大环境部）。从2001 - 2021年开始，该设备被437位研究人员使用，以回收海上110多次科学探险的样品（海上842天），并用于1593 HQP的培训。现在，我们的Box Corer是最近的固定液中最常用的液体，而底栖动物则需要紧急替换，因为它在海上丢失了。此外，我们缺乏在底栖生物学和生物地球化学附近取样的手段。我们寻求资金来多样化我们的加油套件，包括盒子旋塞，锤子，多孔和振动器。盒子，锤子和多旋塞将提供增强的，更精确的访问沉积物 - 水界面的样品。振动器可以穿透固结或更粗的沉积物，从而使我们能够访问沙质或固结层的沉积记录。锤式卫队是一艘小船上浅水工程的理想选择，这可以降低运营成本。该套件一起允许完全集成沉积物采样，从而为新项目打开了大门，并增强了创新。我们还要求为多名，振动器和小型便携式锤式旋转刀提供资金。加拿大海洋学研究的很大一部分依赖于该设备，以便检索北极和圣劳伦斯中地质，生物学和地球化学海洋学所需的沉积物。为了允许对设备的广泛访问，我们维护所有加拿大研究人员都可以访问的工具池，并随时可供任何潜在用户使用。这可以确保所有设备可用于所有个人背景。
