Final answer:
Oceanography is the study of Earth's oceans and includes the study of marine ecosystems, species interactions, and the physical and chemical properties of the ocean. Biogeography examines the geographic distribution of species, critical for understanding environmental impacts on species distribution. Marine ecologists can use non-invasive methods like multibeam echo sounders to study marine life.
Step-by-step explanation:
Oceanography is the study of Earth's oceans. A marine ecologist, as part of their research, would study numerous aspects of the marine environment, including the interaction of organisms within marine ecosystems, physical and chemical properties of the ocean, and the impacts of humans on these systems. Fields such as geomorphology, glaciology, coastal geography, and climatology are all encompassed within physical geography, while biogeography focuses on the geographic distribution of species. To study deep sea corals without harming their habitat, marine ecologists may use techniques like deep sea diving or multibeam echo sounders. The Tagging of Pacific Predators program is an example of how marine scientists use marine animals to gather data about marine ecosystems and biodiversity.
Exercise 1.7.1 hints at other studies within the realm of science such as physiology, geophysics, and agriculture, but not politics as it is not a branch of science.
In the concept of biogeography, understanding the past and present distribution of the world's species is essential for grasping the complex interactions within our physical environment, including those in marine systems. Importantly, biogeographical studies aid in assessing how environmental changes affect species distributions.
It's also notable that biodiversity within marine ecosystems could potentially increase with human intervention through engineering to bolster oceanic food production. This touches the subject of marine biology and ecosystem management.
