IOOS Glider - glos_236-20180726T1435-delayed

Slocum glider data were collected during a western Lake Ontario deployment from 2018-07-26 through 2018-09-05. This deployment was in collaboration with the EPA to examine distribution of tributary inputs. The EPA covered the west side of the lake, while CIGLR operated in the east. The CIGLR glider initially deployed from Oswego, NY traveled in a loop west to Rochester Bay, east to Sodus Bay and then back to Oswego Bay.  This transect was repeated several times.  Note, the glider was deployed in areas of Lake Ontario with at least 30 m of depth.  The glider collected vertical profiles of conductivity, temperature, depth, chlorophyll, colored dissolved organic matter (CDOM), backscatter, and photosynthetically active radiation (PAR) between depths of 0 and 135 m.cdm_data_type = TrajectoryProfileVARIABLES:trajectory (Trajectory Name)wmo_idtime (Profile Time, seconds since 1970-01-01T00:00:00Z)latitude (Profile Latitude, degrees_north)longitude (Profile Longitude, degrees_east)profile_idtime_uv (Depth-averaged Time)lat_uv (Depth-averaged Latitude)lon_uv (Depth-averaged Longitude)u (Depth-averaged Eastward Sea Water Velocity, m s-1)v (Depth-averaged Northward Sea Water Velocity, m s-1)latitude_qc (latitude Variable Quality Flag)longitude_qc (longitude Variable Quality Flag)time_qc (time Variable Quality Flag)depth (m)depth_qc (depth Variable Quality Flag)pressure (Sea Water Pressure, hectopascal)pressure_qc (pressure Variable Quality Flag)conductivity (Sea Water Electrical Conductivity, S.m-1)conductivity_qc (conductivity Variable Quality Flag)...

本数据集为2018年7月26日至2018年9月5日期间，在安大略湖西部部署的斯洛克姆滑翔机（Slocum glider）观测数据。本次部署与美国环境保护署（Environmental Protection Agency, EPA）合作开展，旨在探究支流输入物的空间分布特征。其中EPA负责湖区西侧的观测作业，而五大湖合作研究所（Cooperative Institute for Great Lakes Research, CIGLR）承担东侧区域的运行任务。
该滑翔机初始部署于纽约州奥斯威戈港（Oswego, NY），航行轨迹为向西绕行至罗切斯特湾（Rochester Bay），向东前往索德斯湾（Sodus Bay），随后返回奥斯威戈湾。该航段被重复执行多次。需注意，本次滑翔机的作业区域位于安大略湖水深不小于30米的水域。
滑翔机采集了0至135米水深范围内的电导率、温度、水深、叶绿素、有色溶解有机物（Colored Dissolved Organic Matter, CDOM）、后向散射系数以及光合有效辐射（Photosynthetically Active Radiation, PAR）的垂直剖面数据。
