INTRO TO MARINE SCIENCE FINAL PAPER
TESTED QUESTIONS WITH DETAILED
SOLUTIONS STUDY MATERIAL
●● What are the similarities and differences between Marine Biology
and Oceanography?
Answer: The similarities between Marine Biology and Oceanography
are; they both have many braches
Marine biologists study the organisms that inhabit the sea. •
Oceanographers mainly study the physical (non-living) aspects of the
ocean, including tides, currents, waves, and the chemical make-up of
seawater.
●● Name and describe at least 6 reasons for studying Marine Biology.
Answer: 1. 1. Since life is believed to have arisen in the sea, studying
marine life can provide clues about early life on earth
2. Many products come from the sea including food, medicines derived
from marine species, food resources, and other items used for human
use.
3. Marine organisms produce oxygen used by all kinds of organisms,
including humans.
, 4. The marine environment provides recreation and supports tourism
worldwide
5. The oceans help regulate climate. Water is slow to change in
temperature, keeping coastal land masses more stable year-round.
6. The ocean absorbs much of our CO2, extremely important during this
time of climate change
●● Name several tools used to observe the ocean
Answer: 1. Gliders: Cruise across the oceans for years and collect data
and surfacing to relay the data to satellites.
- Remote sensing: Satellites are used to study large expanses of the
ocean surface.
- Sonar: Used to map seafloor depths and formations.
- Scuba: Used for the study of the marine environment for longer periods
and at depths otherwise unavailable to humans.
- Remotely operated vehicles (ROVs): Allows for direct exploration of
the marine environment when scuba is not an option.
- Research vessels - These floating laboratories allow oceanographers
and marine biologists to explore the marine environments for weeks,
months, or even years without returning to a land-based facility.
- Many types of electronic devices and other gear are currently used to
study the marine environment and its inhabitants
●● SONAR?
