IOOS Glider - ru32-20180109T0531

This project integrated an Acoustic Zooplankton and Fish Profiler (AZFP) multi-frequency echo sounder into a Slocum Webb G2 glider. The AZFP is complemented with existing glider sensors including a CTD, a WET Labs BB2FL ECO puck configured for simultaneous chlorophyll fluorescence (phytoplankton biomass) and optical backscatter measurements, and an Aanderaa Optode for measuring dissolved oxygen. This glider deployment is located in the polynya of Terra Nova Bay (western Ross Sea, Antarctica), and is focused on investigating relationships between phytoplankton-zooplankton-fish distributions and the physical drivers of zooplankton and silverfish species and size distributions.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, seconds since 1970-01-01T00:00:00Z)lat_uv (Depth-averaged Latitude, degrees_north)lon_uv (Depth-averaged Longitude, degrees_east)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, decibars)pressure_qc (pressure Variable Quality Flag)conductivity (Sea Water Electrical Conductivity, S.m-1)conductivity_qc (conductivity Variable Quality Flag)...
