17 SEPTEMBER. ECUADOR. GALAPAGOS: CLIMATE

El Niño in Galapagos, an unusual one. It started in February-to-March with a prolonged warm season. This is, SST and air temperature with an anomaly of +4-5 degrees (26-28 degree instead a 21-22 in normal years). Air temperature follow the sea here in Galapagos, same patterns in ENSO years. February, March, May and April behaved as a strong ENSO (thermocline down to 200 feet), SST up to 29-30 degree in places and heavy rainfall between March-June. But the rain stopped in July. SST carried on like ENSO but no rainfall, almost as dry as a normal year. In fact this month is behaving as should be, "garua season" or misty/drizzle season. The sea is unusually heavy, with big waves and strong wind, and extremely high tides. No clear effects on seabirds and mammals. No mortalities of marine iguanas. Heavy fishing (lots of it illegal), some warm waters species of fish moved into the internal waters (dolphinfish, wahoo, billfish), that normally are only found in the northern side of the archipelago. Good year for finches.--Rodrigo H. Bustamante <rbustama@fcdarwin.org.ec>.
