In the subtropics, why are the surface salinities much higher than the deep-water salinities?

In 2021, Space Technology Company modified its model Z2 satellite to incorporate a new communication device. The company made the following expenditures:

$$\begin{array}{lr} \text { Basic research to develop the technology } & \$ 2,000,000 \\ \text { Engineering design work } & 680,000 \\ \text { Development of a prototype device } & 300,000 \\ \text { Acquisition of equipment } & 60,000 \\ \text { Testing and modification of the prototype } & 200,000 \\ \text { Legal and other fees for patent application on the new communication system } & 40,000 \\ \text { Legal fees for successful defense of the new patent } & 20,000 \\ \text{Total }&\$3,300,000 \end{array}$$

The equipment will be used on this and other research projects. Depreciation on the equipment for 2021 is $10,000.

During your year-end review of the accounts related to intangibles, you discover that the company has capitalized all of the above as costs of the patent. Management contends that the device simply represents an improvement of the existing communication system of the satellite and, therefore, should be capitalized.

Prepare correcting entries that reflect the appropriate treatment of the expenditures.
