Answer

To answer the question "Which sea is referred to as an oceanic desert?" we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Oceanic Desert":**
- An oceanic desert, also known as a dead zone, refers to areas in the ocean that do not support life due to a lack of nutrients and phytoplankton.

2. **Identify the Options Provided:**
- The options given are:
- Red Sea
- Sargasso Sea
- Arabian Sea

3. **Analyze Each Option:**
- **Red Sea:** This sea is known for its biodiversity and coral reefs, so it does not qualify as an oceanic desert.
- **Arabian Sea:** This sea also supports a variety of marine life and is not considered an oceanic desert.
- **Sea of Japan:** Similar to the Arabian Sea, it has a rich marine ecosystem and is not an oceanic desert.
- **Sargasso Sea:** This sea is known for its unique characteristics, including being largely devoid of phytoplankton and having floating seaweeds, which makes it resemble a desert in terms of biological productivity.

4. **Conclusion:**
- Based on the analysis, the Sargasso Sea is the correct answer as it is referred to as an oceanic desert due to its lack of nutrients and low biological productivity.

### Final Answer:
The sea referred to as an oceanic desert is the **Sargasso Sea**.
