A marine research vessel in the Antarctic is transmitting daily scientific data back to a university server via a high-cost, low-bandwidth satellite connection. The data payload consists of CSV files containing raw oceanographic sensor readings (salinity, temperature, and GPS coordinates) alongside high-definition video recordings of ice shelf movement.
To reduce transmission time and satellite costs, the research team must compress the files.
Identify the most suitable type of compression to use for the CSV files containing the sensor readings. Justify your choice.
