Regarding this, what are SST anomalies?
Sea surface temperature is the temperature of the top millimeter of the ocean's surface. An anomaly is a departure from average conditions. Some sea surface temperature anomalies are simply transient events, not part of a specific pattern or trend. Other anomalies are more meaningful.
Subsequently, question is, how are sea surface temperature monitored? Sea surface temperature is a key climate and weather measurement obtained by satellite microwave radiometers, infrared (IR) radiometers, in situ moored and drifting buoys, and ships of opportunity. Different instruments measure the temperature at different depths.
Correspondingly, how are SST anomalies calculated?
The SST anomaly of the LGM relative to the present has been calculated by subtracting the mean SST value of the last 2000 yrs before present (i.e., the modern value of SST).
What is the range for average sea surface temperatures?
This value is well above 16.1 °C (60.9 °F), the long term global average surface temperature of the oceans.
