XBT/XCTD observations, Processing, QC and Applications
during 27-31 January 2025
Organized by
International Training Centre for Operational Oceanography (ITCOocean)
INCOIS, Hyderabad, India.

Overview:

Ocean observations are crucial for understanding the increasing pressures on our oceans, particularly those driven by human activities. The long-term ocean observations enhance our ability to predict and adapt to changes in ocean conditions. Despite advancements in ocean monitoring, significant knowledge gaps remain, with key management-related questions unanswered. Expendable Bathythermographs (XBTs) have been fundamental to ocean temperature profiling since the 1970s, in India providing critical data for mapping expeditions and long-term records of temperature variations. Expendable Conductivity, Temperature, and Depth sensors (XCTDs) complement this by measuring salinity alongside temperature, enabling a more comprehensive analysis of oceanographic conditions. This course provides an overview of XBT and XCTD observations in the Indian Ocean, data processing and particularly applications. Participants will gain practical experience in acquiring and processing temperature and salinity data and deriving critical oceanic parameters such as Mixed Layer Depth (MLD), Isothermal Layer Depth (ILD), and Barrier Layer Thickness (BLT) and identifying the temperature inversions that are essential for assessing ocean variability and health.

Aims and objectives:

  • Provide an introduction to XBT and XCTD ocean observations in the Indian Ocean.
  • Provide hands-on experience in acquiring, processing, and analyzing XBT and XCTD data.
  • Performing Quality Control of the data.
  • Derivation of critical oceanographic parameters such as Mixed Layer Depth (MLD), Isothermal Layer Depth (ILD), and Barrier Layer Thickness (BLT).
  • Assessment of XBT fall rate equation and Bias correction.

    • Learning Outcomes:

    • Understanding of XBT and XCTD data, including temperature and salinity measurements.
    • Ability to acquire, process, and analyze XBT and XCTD data for oceanographic studies.
    • Use of software such as Python, Fortran and Ferret.
    • Knowledge of key oceanographic parameters such as MLD, ILD, and BLT.

      • Course Pre-requisites:

      • Candidates should have a basic understanding of oceanographic data, particularly related to temperature and salinity measurements.
      • Familiarity with data acquisition techniques, especially XBT and XCTD, is preferred but not mandatory.
      • Experience with data processing and analysis using programming tools (such as Python or Ferret) is beneficial.
      • Participants are encouraged to bring their own laptops for hands-on sessions involving data processing.
