Oceanography is the study of the oceans in all their aspects, the plants and animals that live therein, and the geological and geogrophic nature of the basins in which they lie. It is not a single science but the application of many sciences to study in this field. The field of oceanography is

• comprehensive
O glacial
• speculative
controversial

It is important to note that the field of oceanography is comprehensive, as it involves studying various aspects of the oceans such as their physical, chemical, biological, and geological properties. This requires the application of multiple scientific disciplines, including physics, chemistry, biology, geology, and meteorology, among others.

Additionally, the field of oceanography is not speculative, as it is based on empirical evidence and scientific observations. Scientists in this field use advanced technologies and instruments to collect data and analyze it in order to understand the oceans better.

Lastly, while there may be controversies and ongoing debates within certain areas of oceanography, such as climate change and the impact of human activities on marine ecosystems, the field as a whole is not controversial. It is a well-established scientific discipline that contributes significantly to our understanding of the oceans and their importance for life on Earth.
