you can see low pressure zones over the North Atlantic ocean. How are these zones tracked? I cannot imagine there are many monitoring stations in the Atlantic ocean.

Possible ways:

  1. Ships - but I doubt there are enough to get readings over a wide enough area.

  2. Comparison of pressure readings from coastal monitoring stations. Are there enough points for accurate interpolation of the readings?

  3. Aircraft - comparison of GPS altitude to barometric pressure readings could give the surface pressure in a given area. That said, most aircraft travelling over the Atlantic are on specified tracks which may not cover a given area.

  4. Monitoring stations on buoys at well spaced locations in the ocean. Potentially impractical and a hazard to shipping.

Summary

Weather models that assimilate these observations will use sophisticated algorithms to "fill in the gaps" and produce a continuous field of global sea level pressure.

Aircraft can report pressure, but knowing pressure at altitude won't yield sea level pressure without knowing (or making assumptions) about the state of the atmosphere between the airplane and the surface. Upper air observations are good though, and quite important to forecasting and generally much more sparse than ocean surface observations are.
