Effects of the 2015-2016 El Niño on Currents and Temperatures on the Northern Peruvian Coast

Temperatures and currents were measured using equipment moored on an oil platform (4°26.90' S, 81° 20.13' W) off Talara, Peru. The depth of the platform was 45 m at the center and approximately 50 m around the edge. A thermistor chain (RBRconcerto) with 3 m intervals was moored at the center of the platform to determine variations in the vertical thermal structure. An acoustic Doppler current profiler (ADCP, RDI WH300) was moored on the bottom about 80 m to the west of the platform. The sampling intervals were 10 minutes for the thermistor chain and 30 minutes for the ADCP. The equipment was deployed on 6 December 2014, and maintained until 27 May 2016, for one year and five months. As the mooring line of the thermistor chain was lost, however, the thermistor chain data were obtained until 30 December 2015. To obtain the daily data, a median filter was applied to the raw temperature and a two-day moving average to the raw current data. The data in MATLAB binary format and the explanation file were uploaded.
