These studies are carried out to better understand the signal and noise characteristics in the mapping of seafloor structures by altimetry. The results will be used to:

• Advise the General Bathymetric Chart of the Oceans (GEBCO) Working Group on the Integration of Geoscience Data
• Improve altimetry data processing algorithms
• Demonstrate the possibility of higher-resolution mapping using new altimeter technology, such as in the proposed ABYSS mission.
