资源简介:
Glider deployed near Calvert Island BC as part of the C-PROOF glider program. Glider is on a repeat sampling line - the Calvert Line - running from near Calvert Island to beyond the shelf break in Queen Charlotte Sound, before returning to the deployment location.cdm_data_type = TrajectoryProfileVARIABLES:backscatter_700 (700 nm wavelength backscatter, 1)cdom (ppb)chlorophyll (kg.m-3)conductivity (Sea Water Electrical Conductivity, S.m-1)density (Sea Water Density, kg.m-3)depth (m)distance_over_ground (distance over ground flown since mission start, km)heading (glider heading angle, %)instrument_ctd (CTD Metadata, 1)lat_uv (Depth-averaged Latitude, degrees_north)latitude (Profile Latitude, degrees_north)lon_uv (Depth-averaged Longitude, degrees_east)longitude (Profile Longitude, degrees_east)oxygen_concentration (mol.m-3)pitch (glider pitch angle, %)potential_density (water potential density, kg.m-3)potential_temperature (water potential temperature, degree_Celsius)precise_lat (Precise Latitude, degrees_north)precise_lon (Precise Longitude, degrees_east)precise_time (seconds since 1970-01-01T00:00:00Z)pressure (Sea Water Pressure, decibars)profile_direction (glider vertical speed direction, 1)profile_idprofile_index (1)roll (glider roll angle, %)...

本滑翔机部署于不列颠哥伦比亚省(BC)卡尔弗特岛附近,隶属于C-PROOF滑翔机项目。该滑翔机沿重复采样航线——卡尔弗特航线——航行,航线从卡尔弗特岛附近延伸至夏洛特皇后海峡的陆架坡折以外,随后返回初始部署点位。
