The Korea Hydrographic and Oceanographic Administration says it has built a system to monitor currents in northwestern Pacific areas that affect South Korean waters.

The system comprises of algorithms developed by the administration for estimating ocean currents based on satellite data provided by a research center in France.

All substances in the sea move along the currents. Understanding these currents assists in making estimations of climate change in Korea and routes through which contaminants flow into Korean waters.

In addition, ships can use the information to draft faster sea routes, cutting down on fuel costs.
