  • The East Australian Current and Property Transport at 27°S from 2012 to 2013 (37 citations)

In his most recent research, the most cited papers focused on:

  • Oceanography
  • Ecology
  • Climate change

Ken Ridgway spends much of his time researching Oceanography, Boundary current, Sea surface temperature, Climatology and Submarine pipeline. Many of his studies on Oceanography apply to Environmental monitoring as well. His research integrates issues of Biological oceanography, Phytoplankton, Ocean acidification and Plankton in his study of Environmental monitoring.

His work in Submarine pipeline addresses subjects such as Temperature salinity diagrams, which are connected to disciplines such as Continental shelf. Ken Ridgway has researched Downwelling in several fields, including Carpentaria, Tide gauge, Sea level, Altimeter and Monsoon. His work deals with themes such as Thermocline, Climate change, Water mass, South Pacific convergence zone and Equator, which intersect with Thermohaline circulation.
