The Science

Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP) brings together scientists with interests in physical oceanography, the carbon cycle, marine biogeochemisty and ecosystems, and anyone who may use global hydrographic data in their research. By repeating measurements of chemical and hydrographic parameters at decadal intervals, researchers will gain insight on the effects of a changing climate on the physics, chemistry, and biology of the world’s ocean.

Although scientists now have access to data from a global array of surface drifters, 52% of global ocean volume remains upsampled by ARGO floats, therefore ship-based hydrography remains essential for documenting changes throughout the entire water column.

Line I07N will consist of 132 sampling stations between Durban, South Africa and Goa, India. Cruise participants will use various instruments to collect and analyze physical and biological parameters. 

CTD instrument: 24 niskin bottles, referred to as a rosette, collects water samples for analysis

Scientific objectives:

  • Data for climate model calibration and validation
  • Carbon system studies
  • Heat and freshwater storage and flux studies
  • Deep and shallow water mass and ventilation studies
  • Calibration of autonomous sensors
