Workshop Information


The two workshops are brought together 1) to share the state-of-the-art expertise on the historical biases in the records of XBT as well as other temperature instruments to achieve better quality-controlled ocean database, and 2) to discuss current science work carried out with XBT observations and present key scientific results obtained using data from the global XBT network.

The objectives of the two workshops are summarized more specifically as follows.

IQuOD Workshop

The 4th International Quality Controlled Ocean Database (IQuOD) workshop will focus on progress and plans towards production of the first version of the IQuOD database, focusing on automated QC development and the development and implementation of intelligent metadata and uncertainty estimates. We will discuss crowd-sourcing options for expert QC and novel computer-based approaches (such as machine learning). Current and future funding support from SCOR, IODE and other sources will also be discussed.

XBT workshop

  • Looking towards understanding and correcting XBT biases for climate research (e.g. ocean heat content) and physical oceanography studies.
  • Scientific and operational uses of XBT observations, to better understand critical ocean phenomena, processes, such as Meridional Overturning Circulation, currents including Western Boundary Currents, ocean heat budgets.
  • Exploring the synergy of XBT data with data from other observational platforms, such as Argo floats, satellite altimetry, surface drifters, etc.
