Solomon Sea Ocean Transport from Gliders

The western boundary current of the South Pacific Tropical Gyre flows through the Solomon Sea and then to the equator. The degree to which this flow affects the equatorial zone and global climate depends on its transport of water and heat.

These transports have been measured since 2007 by underwater gliders crossing the Sea seasonally to monthly. Ocean temperature and salinity profiles and depth-average current are measured every few km to depths of 500 to 1000 m. Velocity shear can be inferred from measured density. Phenomena of interest are ENSO and flow in the Equatorial Undercurrent.

Science Quality Binned Project Data

Cleaned, post-processed and vertically binned to meet user needs

Project Dataset Processing

  • Averaged to 10-m vertical bins
  • Vertical binning improves ease of use
  • The 10-m bins allow for easy integration of ADCP acoustic backscatter and velocity data
  • Filtered using QC flags
  • Only high-quality data are represented in each bin

Access Options

Data are available in CF compliant NetCDF files and are also available via our ERDDAP server which offers additional file types, data subsetting, visualization options and more.
