Final answer:
The ad-hoc group of oceanographers would need additional hardware for data storage and processing. They could use external hard drives or cloud storage solutions for data storage, and high-performance computers or supercomputers for data processing. Techniques such as data compression and parallel processing can make their research more efficient and lower costs.
Step-by-step explanation:
In order to analyze massive amounts of data on ocean temperatures, the ad-hoc group of oceanographers would need additional hardware for data storage and processing. They could use external hard drives or cloud storage solutions to store the data. For data processing, they may require high-performance computers or supercomputers to handle the computational requirements.
To make their research more efficient and lower costs, the oceanographers could employ techniques such as data compression and parallel processing. Data compression reduces the storage space required, allowing for more efficient storage and retrieval. Parallel processing involves dividing the data and processing tasks across multiple processors simultaneously, which can significantly speed up data analysis.
