Weather buoy tropical Pacific Ocean helped study the El Niño-Southern Oscillation. Moored weather buoys range from in diameter, while drifting buoys are smaller, with diameters of . Drifting buoys are the dominant form of weather buoy in sheer number, with 1250 located worldwide. Wind data from buoys has smaller error than that from ships. There are differences in the values of sea surface temperature measurements between the two platforms as well, relating to the depth of the measurement and whether or not the water is heated by the ship which measures the quantity. The first known proposal for surface weather observations at
Skyline-to-the-Sea Trail passing through a defunct quarry, and terminating in Sanborn-Skyline County Park. This trail would connect to the Skyline-to-the-Sea Trail via a completed section of the Bay Area Ridge Trail. The quarry is owned by the Santa Clara County Roads and Airports Department, which is conducting feasibility studies of this plan.
