C
the average of a decade of sea surface temperatures.
D
the average of sea surface temperatures during an El Nino year.
Explanation: 

Detailed explanation-1: -What is a temperature anomaly? The term temperature anomaly means a departure from a reference value or long-term average. A positive anomaly indicates that the observed temperature was warmer than the reference value, while a negative anomaly indicates that the observed temperature was cooler than the reference value.

Detailed explanation-2: -In 2021, the global ocean surface temperature was 0.65 degrees Celsius warmer than the 20th-century average. Oceans are responsible for absorbing over 90 percent of the Earth’s excess heat from global warming.

Detailed explanation-3: -It is based upon the average anomalies of sea surface temperatures (SST) in the North Atlantic basin, typically over 0-80N.
