What should you do if you see potentially dangerous animal underwater and it does not leave the area?

What should you do if you see a potentially dangerous animal underwater and it does not leave the area? Maintain eye contact and slowly back away. List three different reasons that it is advisable to check with your local dive center before conducting diving in an area you are unfamiliar with.

What tide is when there is no horizontal water movement?

BLANK tide is when there is no horizontal water movement. If you are caught in a rip current, first swim BLANK to the current to get out of it before swimming towards shore. Waves are usually caused by BLANK. Anticipate surge action to avoid contact with stationary objects.

When diving from shore the best time to dive is when there is the least amount of tidal current?

If making a shore dive, the best time to dive is during high-water “slack,” a period of approximately one hour around the turning of the tide when there is minimal water movement. Diving at high-water slack means that the water may be approximately 4 to 6 feet (2 to 3 m) deeper than at low-water slack.

What to do if you see a bull shark while snorkeling?

If you see a shark or shark fin while snorkeling you should head to the nearest safe ground, whether a reef or shallow corals. You should swim quickly but rhythmically so you do not appear in distress. There are typically only 3 sharks that attack humans, namely the Great White, the Bull, and the Tiger shark.

Should you play dead with a shark?

If you're alone in the water, playing dead isn't going to help because sharks prefer to go for more defenseless prey to conserve energy. ... Hit a shark in the nose, eyes and gills to stun it and scare it away. Since blood will attract more sharks, find dry land as a fast as possible to reduce the chance of repeat attacks.

What do you see when diving?

Blue holes — massive sinkholes or caverns usually set in open water — are known for their unique appearance from the surface. These impressions can continue for hundreds of feet — with famous examples in the Bahamas, Belize and China — giving divers a feeling of escape as they descend into the blue darkness.

What to do if you see a shark while spearfishing?

If you've spotted sharks in the area, keep the fish at a safe distance or better still out of the water and start heading back to the boat. Once the fish has been placed in the boat you will usually see the shark break off. However, ALWAYS keep your eye on the shark.

What is responsible for the tides?

Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996). ... Tidal forces are based on the gravitational attractive force.

Where does tide water go?

At low tide, water moves away from you and towards the “bulge” created by the gravitational effect of the moon and/or the sun. Conversely, when the “bulge” is at your location, water flows towards you, giving you a high tide. Technically speaking, water does not actually go far at low tide.

How do you tell which way the tide is moving?

You can tell if the tide is coming in or out by reading a local tide table since they list the predicted times that the tide will be highest and lowest. In the time that the tide shifts from its lowest point to its highest point, the tide comes in.

How does tide affect the divers?

Therefore, tides affect diving conditions – in both good and bad ways. ... This is because water is being pulled towards the moon on one side of the earth and the earth pulled away from the water on the other side of the earth, creating a bulging effect and a high tide at opposite sides of the earth.

What tide is best for diving?

Under most circumstances, diving at high tide yields the best visibility because it brings with it clear, offshore water. If you think current may be a factor in your dive plan, the ideal time to enter the water is around what's termed a slack tide.
