🌊 Ocean Research Lab

Plan dives, mapping, and biological expeditions in the World Ocean

Explore ocean depths

The ocean covers over 70% of the planet but a significant part remains unexplored. This page will help oceanographers, engineers, and researchers model deep-sea missions, energy requirements, and data collection.

Three calculators cover embedding planning, hydrographic data processing, and energy balance of autonomous devices.

1. Submersible Ballast Plan

Calculate maximum depth, stay time, and oxygen supply for diving.

2. Ocean Mapping

Evaluate the scan area, resolution, and mission time for hydrophones.

3. Energy Balance AUV

Calculate energy consumption of autonomous device accounting for systems, sensors, and temperature.

TYPES OF EQUIPMENT

  • DIVING SUBMERSIBLE WITH CREW (DSRV, ALVIN).
  • AUV — autonomous underwater vehicles (REMUS, Hugin).
  • ROV — remotely operated vehicles (Jason, Victor 6000).

SCIENTIFIC TASKS

Geology (plate tectonics, hydrothermal sources), biology (deep-sea ecosystems, bioluminescence), cartography, resource search

INFRASTRUCTURE

Scientific research vessels, satellite communication, ARGO buoys, sensor networks, data centers for processing Big Data.

Safety

Plan emergency spills, oxygen reserve ×1.5, duplicate systems, continuous pressure and leak monitoring.

Ecology

Minimize noise impact, avoid coral damage, use drones for monitoring plastic pollution, adopt 'green' ship energy.

❓ FREQUENT QUESTIONS ABOUT OCEANIC MISSIONS

1. What is the maximum depth for a bathyscaph?
The Mariana Trench is 10 984 m deep. The bathyscaphes 'Trieste' and 'Deepsea Challenger' reached depths over 10 900 m.
2. How are data transmitted from AUV?
Through acoustic modems underwater, during spill — through satellite or Wi-Fi to the mother ship.
3. Which sensors are used?
Multi-beam sonars, CTD (conductivity, temperature, depth), cameras, spectrometers, hydrophones, chemical analyzers.
4. How to evaluate the impact of water depth?
Every 10 meters adds 1 atmosphere of pressure. At 3,500 m — ~350 atm. Structures use titanium spheres and composites.
5. HOW TO PLAN AUV ENERGY?
All systems must be accounted for: thrusters, navigation, sensors, temperature, return reserve. Batteries usually last 12–48 hours.
6. How is the ocean floor mapped?
Multibeam sonars scan the seabed; the AUV moves in "lawnmower" patterns, and the combined data forms bathymetric maps accurate to within tens of centimeters.
HOW TO PROTECT EQUIPMENT FROM CORROSION?
ANODIZED COATINGS, SPECIAL SURFACES, RINSING WITH DEIONIZED WATER, USE OF TITANIUM AND COMPOSITES, MICROBIOLOGICAL CORROSION CONTROL
8. WHAT DATA ARE COLLECTED FOR BIOLOGY?
water samples, DNA, temperature measurements, oxygen, salinity, photo and video fauna, acoustic signals
9. How do the devices track?
Hydroacoustic buoys, inertial navigation, DVL (Doppler Velocity Log), GPS during descent, visual bottom markers
10. WHAT RISKS DO MISSIONS FACE?
Connection loss, leaks, limited energy, mechanical damage, pressure drops, poor visibility, sensor data lag

📖 Manual with examples

Example 1: Submerge

Crew 2, oxygen 14 hr/person, depth 4,000 m, speed 25 m/min

Time of descent = 4 000 / 25 = 160 min (2.67 hours) Time of ascent = 160 min Dive reserve = 28 hours → at the bottom you can stay ≈ 28 - 5.34 = 22.7 hours

Example 2: Cartography

Width 3 km, length 120 km, step 150 m, speed 3 knots (5.56 km/h).

Area = 360 km² Passages = 3 000 m / 150 m = 20 Path length = 120 × 20 = 2 400 km Time ≈ 2 400 / 5.56 ≈ 432 hours

Example 3: Energy

Power 150 kW·h, base consumption 2.8 kW, sensors 1.4 kW, coef. 0.8.

Total consumption = (2.8 + 1.4) / 0.8 = 5.25 kW Operation time = 150 / 5.25 ≈ 28.6 hours

Example 4: Hydrothermal Sources

Temperature 350 °C, distance 2 km from base.

CONCLUSION:Use ROVs with heat-resistant cables and sensors.

Example 5: Microplastic Analysis

Collect 50 water samples, FTIR spectroscopy, statistical verification.
