资源简介:
The overarching goal of the California Underwater Glider Network is to sustain baseline observations of climate variability off the coast of California. The technical approach is to deploy autonomous underwater gliders in a network to provide real-time data.The CUGN uses Spray underwater gliders making repeated dives from the surface to 500 m and back, repeating the cycle every 3 hours, and traveling 3 km in the horizontal during that time. The CUGN includes gliders on three of the traditional cross-shore CalCOFI lines: line 66.7 off Monterey Bay, line 80 off Point Conception, and line 90 off Dana Point. The glider missions typically last about 100 days, and cover over 2000 km, thus providing 4-6 sections on lines extending 300-500 km offshore. Since 2005 the CUGN has covered 200,000 km over ground in 28 glider-years, while doing 90,000 dives.cdm_data_type = TrajectoryProfileVARIABLES:chlorophyll_a (Chlorophyll-a concentration, mg.m-3)chlorophyll_a_qc (chlorophyll_a Quality Flag)conductivity (Sea Water Electrical Conductivity, S.m-1)conductivity_qc (conductivity Quality Flag)density (Sea Water Density, kg.m-3)density_qc (density Quality Flag)depth (m)depth_qc (depth Quality Flag)dissolved_oxygen (micromol.kg-1)dissolved_oxygen_qc (dissolved_oxygen Quality Flag)instrument_ctd (CTD Metadata, 1)instrument_doxyinstrument_fchllat_qc (latitude Quality Flag)lat_uv (Depth-averaged Latitude, degrees_north)lat_uv_qc (lat_uv Quality Flag)latitude (Profile Latitude, degrees_north)lon_qc (longitude Quality Flag)...

加州水下滑翔机网络(California Underwater Glider Network, CUGN)的总体目标是维持加利福尼亚近海气候变率的基准观测。其技术方案为部署自主水下滑翔机构建观测网络,以获取实时观测数据。该网络采用Spray型水下滑翔机,可在海面至500米深度间反复完成下潜与上浮循环,每3小时完成一个完整循环,此期间水平航行距离可达3公里。 CUGN的观测站点覆盖三条传统跨岸CalCOFI航线:蒙特雷湾外侧的66.7号航线、康塞普西翁角外侧的80号航线,以及达纳角外侧的90号航线。单架滑翔机的任务周期通常约为100天,累计航程超过2000公里,可在向海延伸300至500公里的航线上完成4至6个观测断面。 自2005年以来,CUGN已在28个滑翔机作业年度内累计航行20万公里,完成9万次下潜作业。 通用数据模型(Common Data Model, CDM)数据类型为轨迹剖面(TrajectoryProfile)。 包含的变量如下: - chlorophyll_a:叶绿素a浓度(Chlorophyll-a concentration,单位kg·m⁻³) - chlorophyll_a_qc:叶绿素a质量控制标记(chlorophyll_a Quality Flag) - conductivity:海水电导率(Sea Water Electrical Conductivity,单位S·m⁻¹) - conductivity_qc:电导率质量控制标记(conductivity Quality Flag) - density:海水密度(Sea Water Density,单位kg·m⁻³) - density_qc:密度质量控制标记(density Quality Flag) - depth:水深(单位m) - depth_qc:水深质量控制标记(depth Quality Flag) - dissolved_oxygen:溶解氧(单位micromol·kg⁻¹) - dissolved_oxygen_qc:溶解氧质量控制标记(dissolved_oxygen Quality Flag) - instrument_ctd:CTD元数据(CTD Metadata,取值为1) - instrument_doxy:溶氧仪相关数据 - instrument_fchll:荧光叶绿素相关数据 - lat_qc:纬度质量控制标记(latitude Quality Flag) - lat_uv:深度平均纬度(Depth-averaged Latitude,单位为北纬度数(degrees_north)) - lat_uv_qc:lat_uv质量控制标记(lat_uv Quality Flag) - latitude:剖面纬度(Profile Latitude,单位为北纬度数) - lon_qc:经度质量控制标记(longitude Quality Flag)……(另有54个变量)
