Final answer:
The statement 'Others explore the deep ocean' is not a fragmented question but a statement about marine exploration. Marine biology encompasses the study of ecosystems in oceanic zones like the abyssal zone, using methods that avoid environmental damage.
Step-by-step explanation:
The question 'Others explore the deep ocean' is not a fragmented question; it seems to be a statement lacking context for a full discussion. However, if you are seeking information on how scientists explore and study the deep ocean, the field of marine biology offers many methods. Marine biologists utilize technologies like multibeam echo sounders and engage in deep-sea diving to study marine ecosystems without harming them.
They tag and track marine animals to understand their ecosystems and behavior's. The exploration of the abyssal zone, which lies at depths of 4000 m or greater, reveals a world without sunlight, where chemosynthetic bacteria form the base of a unique food chain surrounding hydrothermal vents.
