CCGS John P. Tully Sub-bottom Profiler Deployed 2013-05-08

The Knudsen CHIRP 3260 (S/N K2K-12-0107) was deployed on 2013-05-08 on CCGS John P. Tully. The Canadian Coast Guard Ship (CCGS) John P. Tully is owned and operated by the Canadian Coast Guard. This device is a Sub-bottom Profiler. A sub-bottom profiler is an echosounder that penetrates beneath the seafloor. The backscatter data serves to obtain bathymetric data, and identify and characterize layers of seafloor and subseafloor sediment or rock. The frequency influences the range and spatial resolution. It was deployed on a mobile platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 3.0 digital infrastructure, with quality assurance and derived data products following established practices.Knudsen CHIRP 3260型设备（序列号S/N K2K-12-0107）于2013年5月8日搭载于加拿大海岸警卫队“约翰·P·塔利”号（CCGS John P. Tully）。加拿大海岸警卫舰船（Canadian Coast Guard Ship，缩写CCGS）“约翰·P·塔利”号由加拿大海岸警卫队所有并运营。该设备为海底剖面仪（Sub-bottom Profiler），是一种可穿透海底下方的回声测深仪（echosounder）。其背向散射数据可用于获取水深地形数据，同时可识别海底及海底以下沉积物或岩层的层理结构与特征。设备工作频率会对探测量程与空间分辨率产生影响。该设备搭载于移动平台完成部署。此次部署产生的所有数据均已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外共享，相关数据遵循既定规范开展质量保证工作并制作衍生数据产品。
