A marine biologist is investigating the impact of ocean warming on the nesting habits of green sea turtles (Chelonia mydas) along a specific coastline.
During the nesting season, the biologist conducts nightly patrols of the nesting beaches to count and record the precise number of nesting attempts and eggs laid by each turtle.
To contextualise these observations, she also downloads historic sea surface temperature (SST) records for the region over the past 30 years from the National Oceanic and Atmospheric Administration (NOAA) database.
Referring to this investigation, explain the difference between primary and secondary data.
