GLIDERSCOPE software

GLIDERSCOPE description

GLIDERSCOPE is an IMOS Ocean glider Facility Windows platform software package designed to allow users quick and easy visualisation of Ocean glider oceanographic data, via a convenient graphical user interface. In accordance to IMOS data file convention, Ocean glider data formats are based on NetCDF (Network Common Data Form). All of the scientific data are stored with appropriate quality control flags indicating the usability/validity of each data-entry. Although highly informational, NetCDF files can be quite daunting for those who are unfamiliar with the format, or lack the computing set-up to access the data.

By using the freely available GLIDERSCOPE software, all users will be able to read the NetCDF files, filter out the bad data and apply a variety of useful data graphical visualisation techniques to examine the data, e.g. using three/four-dimensional plots of water properties, interpolated contour charts, vertical profile plots, water properties comparison charts, etc. Users can easily choose and extract segments of data. Additionally, users can also export their data to text or NetCDF files for easy access in other applications.

* GLIDERSCOPE V7.1 (International) is now available *

New features include:

  • Ability to handle Glider NetCDF datafiles from international facilities.

Overseas data can be freely downloaded from the European Everyone’s Gliding Observatories (EGO) ftp://ftp.ifremer.fr/ifremer/glider/v2/

and the U.S. Integrated Ocean Observing System (IOOS) https://data.ioos.us/gliders/erddap/info/index.html

  • Version 7 calculates Light Attenuation Coefficients (Kd) and calculates the 1% photic depth level. Users can compare Kd of different frequencies of light as well as compare these with depth averaged CDOM, chlorophyll and backscatter coefficients.
  • Nitrates can be visualised  (e.g. selected StormBay missions).
  • Drop a 'virtual Niskin bottle' to instantly find out what the water properties are like anywhere in your cross-section.
  • Isolate a layer of water in your plot using your mouse! Instantly examine the TS-diagram of this layer or display the layer in various ways.
  • Zoom into the plots and tweak the colour scale automatically or using handy sliders.
  • Improved data export now allows depth averaged water velocities to be saved in netCDF files, and all scientific data types to be saved at once with the push of a button.
  • Time axes in plots are more dynamic, conveniently changing units from months to days to hours. You can also switch easily to view local times to get a feel for whether daylight drives certain ocean processes.
  • Gliderscope V7 Matlab APP is now backward compatible. No need to download different versions for different installations of Matlab.
