Two Years of Oceanographic and Meteorological Data from the UNAM Buoy Anchored at Socorro Island in the Mexican Pacific

Abstract

The paper analyzes oceanographic and meteorological data registered by an oceanographic buoy in the Mexican Pacific. In 2005 the Marine Science and Limnology Institute of the National Autonomous University of Mexico moored an oceanographic buoy off the coast of Socorro Island in the Mexican Pacific that transmitted data hourly from July 11, 2005 to November 15, 2007. The buoy recorded oceanographic (current speed and direction, conductivity, temperature, salinity, density, turbidity, pH, fluorescence, sea level, waves, and tides) and meteorological (wind speed and direction, temperature, relative humidity, and pressure) data. Linear spectral analysis and wavelet analysis revealed annual, seasonal, and biweekly frequencies, as well as frequencies associated with the main tidal components, and those corresponding with inertial oscillations and Madden-Julian oscillations.
