Excuse me. How to observe the clear and turbid seawater? What is the best time to dive?

The clarity and turbidity of seawater can be observed and compared with the naked eye, or it can be measured using a water quality analysis instrument. For the determination of the best time to dive, the influence of tides and currents needs to be considered.

Here are some specific suggestions:

1.Observe the clarity and turbidity of the seawater:

Naked eye observation: Observe the transparency of the sea water through the naked eye or swimming goggles. Generally speaking, if the water is clear, it will be transparent, and if the water is turbid, it will be muddy. It is also possible to observe sediments and biomes on the seafloor to learn about the pollution of seawater.

Comparative observation: Comparison with the surrounding sea or other sea areas. If you find that a certain area of water is significantly less transparent than others, it may indicate that the water quality in that area is poor.

Use of water quality analysis instruments: The clarity and turbidity of seawater can be measured more accurately by using specialized water analysis instruments. These instruments can often measure the turbidity, transparency, suspended solids concentration, and other indicators of seawater.

2.Choose the best time to dive:

Consider the influence of tides: During high and low tides, the currents can be rapid, which can affect diving safety. Therefore, the period of low tide (i.e., the period of calm between high and low tide) is the best time to dive. Flat tide times can be found by consulting the local tide table.

Consider the effects of ocean currents: Ocean currents (i.e., large-scale movement of seawater) can also affect diving. In general, currents are more pronounced in the morning and evening, so special attention needs to be taken to dive during these two times.

Consider water temperature: Water temperature can also affect diving. In general, periods of higher water temperature are more suitable for diving, as high water temperatures can improve the diver's mobility and comfort in the sea.

In conclusion, there are many factors to consider when choosing the best time to dive, including tides, currents, water temperature, etc. In practice, judgments need to be made based on local conditions.

The best time to dive is the "flat tide" time The so-called flat tide refers to a buffer period after the end of high tide and the end of low tide Of course, the tide is not very obvious in the offshore bay You can check the tide table The sea water is relatively clear at low tide The main thing is that it is safer to dive at low tide The flow speed is too fast at high tide and low tide It is quite dangerous.

Every year from November to March.

If you want to play in the sea, such as diving, the best season is summer, April to August, when the underwater scenery is at its best.

Staggered peak tour to find out··!

Basically, there are a lot of people in Sanya from October 1 to April, because everything else has begun to cool down

April to September is the best time for diving in Hainan

Of course, at high tide (within three hours) the water is at its clearest. At low tide, the sea is relatively turbid, and if the local sea area is not developed into a bathing area, there will be an undercurrent below. So it is recommended that you choose to go when the tide is high.

When the sun is about to set, it won't explode**.

I think it's best in the morning because the sea ice is better in the morning and it makes us exercise.

Hello, it's best not to go to Sanya these days. A very strong typhoon cannot go into the sea.

It is recommended that you choose another day to go Oh, I wish you a good time, thank you.

1. Adjust all the hues. Brush out the selection of areas of sea water, add adjustment layers, hue adjustments, and carefully move the slider to pick the most appropriate color.

China's best sea water is in Xisha Yongxing Island (Nansha can't be traveled, not to mention), ** water is the Maldives, the hotel can't be Maldives. The problem is where to go is very difficult. Secondly, it is estimated that there is Taiwan's Lanyu Island (it is estimated that Green Island is also good, but a little unlucky) underwater visibility of 30-40 meters, such as diving or daze, which is indeed a good place, there are better conditions for the "homestay", but it is also a little difficult for us to go to the mainland, if you are interested in Taiwan to travel freely, Lanyu is a good choice.

In the down, it can only be Sanya Yalong Bay and Wuzhizhou Island next to it, as long as you have money, you can enjoy it.

The coral island of Yantai can be seen three meters underwater.

In the eastern part of the United States, at the center of the North Atlantic circulation, there is a sea area that has been called "the most dangerous in the world", but unlike the muddy waters seen in science fiction movies, this sea is unusually clear. This area of water, called the Sargasso Sea, is about 2,000 nautical miles long and 1,000 nautical miles wide.

The South China Sea is one of the most rarely heavily polluted oceans, so the water is clean. This has to do with the fact that there are not many polluting companies in Hainan, and it also has to do with the marine protected areas there. So I suggest you go to Sanya!

Sanya, Hainan Province, Qinhuangdao used to be good, but some time ago there was an oil leak, and the water quality was not as good as before.

Guangdong

I just went to Shandong, and the sea in Weihai is still good, but the sea in Rizhao and Qingdao is full of algae, and it smells terrible.

Looking at some small rivers in Guangzhou, I don't know how dark it is, but the sea here is still very good, Haiquan Bay, Red Bay, China's first beach, there are many, many more.
