How are underwater caves different from land caves?
  • Underwater caves are basically just a hollow rock at the bottom of the ocean. They are very small compared to caves on land, and are basically just a single room.
How are underwater plants different from air plants?
  • Heterophyllous amphibious species form morphologically and anatomically distinct leaf types under water as compared to in air (Sculthorpe, 1967). The underwater leaf forms are an acclimation that enhances underwater gas exchange (Sand-Jensen et al., 1992; Colmer et al., 2011).
How is underwater cutting different from surface cutting?
  • Underwater cutting has many common points as with those carried out on the surface. The difference is in the special equipment required and qualified divers engaged in it, who strictly abide by the safety rules.
How is underwater vision different from air vision?
  • They are also blurred by scattering of light between the object and the viewer, also resulting in lower contrast. These effects vary with wavelength of the light, and color and turbidity of the water. The vertebrate eye is usually either optimised for underwater vision or air vision, as is the case in the human eye.
How is underwater welding different from dry welding?
  • Although we normally picture underwater welding being done while fully submerged in water, most of it is done in dry habitats. Dry welding makes use of a dry chamber or habitat (hyperbaric chamber) where water is replaced by a mixture of gas so one or multiple welders can do the job in dry conditions.
Is underwater based on cthulhu?

Director William Eubanks Confirmed The Monster In Underwater Is Cthulhu. William Eubanks confirmed in an interview with Youtube reviewer Mr. H that the deep-sea creature was, in fact, Cthulhu… Both the movie and the book preface the rise of the monster with an earthquake, a precursor to the true horror.

How are underwater flares different from open air flares?
  • Underwater flares contains oxidizers like nitrate or sulphate for burning (oxidizing) magnesium. The ratio of oxidizer to fuel is larger than the open-air flares.
How is casting underwater different from casting in air?
  • Casting underwater is different from casting in air, this is true. How you handle this is up to you. This Enworld discussion shows a few ways other DMs handle it, in the order of their appearance in that thread:
What is different from stick welding to underwater welding?

Divers usually use around 300–400 amps of direct current to power their electrode, and they weld using varied forms of arc welding… Wet welding with a stick electrode is done with similar equipment to that used for dry welding, but the electrode holders are designed for water cooling and are more heavily insulated.

What are the applications of underwater sensor nodes?
  • Underwater sensor nodes will find applications in oceanographic data collection, pollution monitoring, offshore exploration, disaster prevention, assisted navigation and tactical surveillance applications.
What is an underwater wireless sensor network ( uwsns )?
  • 5 Abstract:Underwater wireless sensor networks (UWSNs) consists of variable number of sensor and vehicles that are deployed to perform concert monitoring tasks over a specified area in the ocean.
What's the distance of an ultrasonic underwater sensor?
  • As Michael Karas pointed out, that ultrasonic sensor is rated from 30cm-3m, sorry. However, this site may have another suitable option. You could create your own module with an underwater transducer. You should read this if you haven't already.
Which is the best sensor for underwater video?
  • As with photography, larger sensor sizes, like a super35 sensor, allow you to capture more light resulting in better dynamic range and quality in low light. However, APS-C, micro four thirds, and even 1" sensors produce very respectable video.
Is underwater based on true story?

But is 'Underwater' based on a true story? To answer simply, it is not. Though like a good science fiction it is rooted in reality. The film takes inspiration from real-life mysteries and issues, along with folklores and classic creature horrors.

What is underwater weighing based on?

What's the name of the underwater weighing test?

  • Hydrostatic weighing, also known as Hydrodensitometry or underwater weighing, is a classic measure of body composition. The test involves the subject being lowered into a water tank until all body parts are emerged, expelling all the air from the lungs, then weighed.
How are plants that survive underwater different from other plants?
  • There are a number of characteristics that underwater plants share with each other. For instance, most plants that live in water do not need any cuticles, and if they have any, they are very thin. A cuticle is a part of the plant that prevents water loss.
How is an underwater volcano different from a land volcano?
  • An explosive eruption occurs on land when these dissolved gases are released suddenly—think of the bubbles in a coke bottle spurting out when a shaken bottle is opened and the pressure is released all at once. But underwater the magma still faces the crushing pressure of tons and tons of ocean water once it reaches the seafloor.
How is an underwater wind turbine different from a windmill?
  • Underwater turbine is similar to windmill turbine except underwater turbines harness natural currents to generate electricity, while wind turbines harness natural winds to generate electricity.
Are underwater red filters different?

Underwater filters and red filters do not "add in" color, they subtract other wavelengths. This means you have some loss of light, so you may have to shoot at a higher ISO underwater or wider aperture in order to get a high enough shutter speed in your underwater photo.

Are underwater welding machine different?

This equipment can vary in range of price, quality and effectiveness… And just as in surface stick-welding, underwater welders must choose the correct stinger angle and electrode diameter to fuse the seam.

How is underwater welding different?

Underwater wet welding insulates its electric cables twice. It only uses direct current for its power source (as opposed to alternating current) and most commonly incorporates negative polarity. The system also adds a knife switch along the cables. Their knife switch keeps the power turned off to their welding stinger.

Why is sound different underwater?

Why does sound sound different on dry land than underwater?

  • When you’re on dry land, sound moves through air and hits your fleshy ear. Air is so different from flesh that the sound waves are able to vibrate off your fleshy bits. Underwater, your fleshy bits might as well be just more water as far as the sound waves are concerned. That’s because you’re made of water. On average, 65 percent of you is H20.
Does anyone make an oxygen level sensor for underwater?

How do electrochemical oxygen sensors work?

  • Electrochemical oxygen sensors are primarily used to measure oxygen levels in ambient air. They measure a chemical reaction within the sensor that creates an electrical output proportional to the oxygen level.
What are the characteristics of an underwater sensor network?
  • Underwater Sensor Networks Architecture Underwater network’s physical layer utilizes acoustic technology for communication. Limited bandwidth, capacity, and variable delays are characteristics of acoustic technology. Therefore, new data communication techniques and efficient protocols are required, for underwater acoustic networks.
