Exam Questions and Answers With complete solution–Expert
Verified | Latest Questions 2025-2026
What types of vessels are used in ocean exploration? - Vessels of all shapes, sizes,
and materials, including rafts, research ships, and submarines.
What is the purpose of ocean vessels? - They can travel for pleasure, work, carry
passengers or cargo, and include explorers.
What is an autonomous underwater vehicle (AUV)? - A device powered by buoyancy-
based propulsion that follows a down-and-up profile through the ocean and can take
oceanic readings for years.
What is the most important tool of oceanographers? - The oceanographic research ship.
What capabilities do modern oceanographic research ships have? - They are designed
for long voyages and can carry a crew of thirty-five or more scientists.
What facilities do oceanographic research ships typically include? - Wet and dry
laboratories, libraries with satellite connections, and specialized propulsion systems.
What type of engines do oceanographic research ships use? - Steam turbine or diesel
electric engines designed for low and high speeds.
What is dynamic positioning in the context of oceanographic research ships? - The
ability to maintain a constant position using thrusters and propellers.
What types of equipment do oceanographic research ships carry? - Radar, satellite
tracking gear, helicopter landing pads, deep sea vehicles, heavy cranes, winches,
bathythermographs, and precision depth recorders.
What are Nansen bottles used for? - To measure temperatures and collect water
samples at specific depths.
What instruments are included in oceanographic research? - Underwater video
cameras, salinity/temperature/depth sensors, and current meters.
What significant achievement is associated with the Glomar Challenger? - It completed
an important drilling program of 1,092 holes at 624 sites throughout the world's oceans.
What was the total length of cores extracted by the Glomar Challenger? - 60 miles (97
km) of cores.
, When was the Glomar Challenger retired? - In 1983.
What is the role of satellites in modern oceanographic research? - They show current
patterns of the seas and water-surface temperature.
How do ocean buoys contribute to oceanographic research? - They transmit gathered
data to satellites, which then transfer it to shore bases or research vessels.
What is the significance of wide-open, uncluttered working decks on research ships? -
They are essential for effective operation and research activities.
What type of studies can be conducted using powder magazines on research ships? -
Underwater explosion studies to measure reflected sound waves.
What fraction of the ocean can surface ships and divers using scuba gear investigate? -
Only a fraction of the ocean.
What is the main challenge faced by vessels navigating the ocean? - Meeting the
ocean's demanding requirements.
What is the purpose of using variable-pitch propellers on oceanographic ships? - To
provide greater maneuverability at slow speeds.
What is the significance of having temperature-controlled areas on research vessels? -
They are necessary for sensitive scientific experiments and analyses.
What device was used by Beebe and Barton in the 1930s for deep-sea exploration? -
The bathysphere, a hollow steel ball lowered by a cable.
What was the maximum depth reached by Beebe and Barton in their bathysphere? -
3,028 feet (923 m) in 1934.
Who built the bathyscaph, and what was its significance? - Auguste Piccard built the
bathyscaph, which could ascend and descend freely without cables.
What are submersibles, and what is their purpose? - Sophisticated research
submarines used by oceanographers and engineers to explore and observe the ocean
with minimal disturbance.
What technologies are commonly equipped on modern submersibles? - Coring devices,
mechanical arms, video cameras, and sonar.
What is the operational depth range for most deep-sea cameras? - From 600 feet (183
m) to 9,842 feet (3,000 m).
