Chapter 143 After the Typhoon
On the day of the storm in Lanhai City, Hongming Village along the coast ushered in a typhoon that had been warned in the weather forecast.

The students of Ocean College packed up the outdoor equipment one after another, and piled them all into the warehouse of Li Chengxin's house.

During the typhoon, Professor Yang gave them all a vacation. He stayed in Hongming Village, lived in a resort, and sorted out the information he had collected previously with his graduate student Xiao Jia.

Between Hongming Village and Zhangba Island, the sea area is calm all year round and ships come and go. At this time, there is not a single ship. The staff of Zhangba Island have evacuated long ago. The villagers of Hongming Village and the residents of the town are all Take this seriously.

Under the typhoon, the sea level rose significantly, and the seawater overflowed into the inland to erode the soil, and the floating garbage was brought ashore by the waves.

Li Chengxin originally wanted to stay in the boathouse, relying on the attribute bonus of Anfeng Zhenhai in his boathouse, but the sea water flooded half of the first floor of the boathouse, and finally decided to go back to the higher ground before he could not go downstairs. In the parents' house.

A few days later, the sea calmed down, the students came back one after another, and the ocean observation activities continued.

"I thought it would be a mess here." Professor Yang stood under Li Chengxin's boathouse, looking at the experimental coast.

Li Chengxin answered while picking up fallen leaves and garbage on the artificial beach: "That's what I thought. It didn't seem to have much impact. Even the tiles of the houseboat were safe."

"There's just a lot less sand on the beach." Zhou Hao hit the nail on the head. It's time for the artificial beach at his resort to be replenished with sand.

Professor Yang fiddled with the equipment he left on the coast to measure the wind speed: "The wave height is not very high, and the wind strength is between 3.4m/s and 7.9m/s. Compared with most disaster-stricken areas, this sea area can basically It’s said that everything is calm.”

According to the data given by Professor Yang, Zhangba Island just blocked the wind here.

"It just so happens that the fish will take refuge in this sea area to avoid the strong wind. Although the typhoon has passed for a few days, there should still be a lot of fish hiding here. Let's see what else is there!" Professor Yang took out We received new equipment brought by the returning students.

The new equipment is placed in a box, and the outer packaging says "observation underwater robot ROV".

"Wow! Underwater robot!" Seeing the English word "ROV", Li Chengxin immediately knew what it was.

"ROV" stands for "Remote Operated Vehicle", which is an unmanned remotely operated vehicle. It is an operating robot that works underwater and is usually used for extreme deep-sea operations. Unexpectedly, Li Chengxin could see it on his own coast.

Professor Yang smiled: "It's just a junior version. It only has the function of shooting while moving in the water."

This version of the underwater robot can be directly controlled by a computer, and is equipped with a movable high-definition camera that can transmit real-time images.

A student helped debug Li Chengxin's computer, and another student helped put the underwater robot into the water smoothly.

Li Chengxin tried to control the underwater robot with the mouse. He was a young man, and he got started after playing with it for a while. Soon he was able to operate the robot to make it retreat, rotate, rise, and dive.

【Fun and fun!Want to buy want to buy! 】

[The reaction speed is very fast! 】

[When moving forward, the propeller behind did not stir up the sand on the seabed, it was very smooth! 】

Through the computer screen, several people clearly saw the seabed scene of this coast.

The sunlight reflects the winding and floating bright lines on the bottom of the sea along with the waves, and the beach on the bottom of the sea is somewhat undulating.

When the first creature was discovered, the underwater robot had already run 20 meters away.

It was a red stingray. The body of the fish was diamond-shaped, and the skin folds could be seen at the tail. There was a column of small spines from the midline to the tail. The length of the tail was not twice as long as the body disk.

"Hey, it turns out to be a red stingray. At first I thought it was a Chinese horseshoe crab."

"Surprisingly, it looks so thick from this angle."

The underwater robot circled the red ray several times, causing the students to talk about it.

"So the red stingray ran so close to the shore because it's not good at swimming?"

The red stingray, which was disturbed by the underwater robot, ran away, swaying the fins on both sides that were integrated with the body like waves.The raised sea sand blocked the sight of the underwater robot and lost the trace of the red stingray.

At this time, the underwater robot was already close to the edge of the coast contracted by Li Chengxin, and reached the vicinity of the biological water purifier and the mussel farming floating platform.

The space between the floating platform and the mussels is very dark. With the background light outside the floating platform, you can see a school of small fish swimming under the floating platform.

The underwater robot chased the group of small fish out of the floating platform, and only then did they see the true colors of the group of fish.

"Is this a tropical fish?" The black stripes on the fish's body instantly make people recognize it. Who is a marine major who hasn't raised a few triangular tropical fish with black stripes on a white background.

"The scientific name is Black Star White Pomfret. It is a very popular ornamental fish, but when it grows to 30 centimeters long, it can basically be eaten." Li Chengxin introduced.

"The existence of this small group may be due to the typhoon. After all, it is not a local fish species, and it should have swam here to escape the strong wind. Moreover, this small fish is more afraid of threats from above, so it hides in Below the floating platform." Professor Yang also added.

"Threats from above?" A student was a little unresponsive.

But soon, everyone remembered the cormorant photographed before, which is a threat to all fish in the vicinity.

The underwater robot continued to move forward, and not long after, it saw something trying to bury itself in the sea sand. When the underwater robot took the photo, only half of its carapace was left exposed on the sand, and there were barnacles on the carapace. faintly visible.

"Shellfish? Probably abalone." Before the sea urchins became rampant, abalone was one of the specialties of Hongming Village.

The appearance of the underwater robot may have made it feel threatened. After a burst of turbid sea sand, a Brazilian turtle swam out of the turbidity. The barnacles on the carapace made everyone confirm that it was the "abalone" photographed before.

"Hey, there is actually a Brazilian tortoise." They only caught one when they were observing the flounder a few days ago, but this one is a little far from the coast, so let it go and let it fend for itself.

"The Brazilian tortoise only needs to surface once a week to breathe, so it's really hard to catch."

The underwater robot continued to move forward. It had passed the tidal flat created by Li Chengxin and reached the rocky area of ​​Hongming Village itself.When we get here, the water is obviously deeper, but the sun can still shine on the rocks on the seabed.

"Hey, I found it!" On a stone, three small sea cucumbers, one red, one green, and one black, were safely stuck in the cracks of the stone.

This is sea cucumber, exactly the species of sea cucumber seedlings that Li Chengxin and Xiao Jia threw down last winter.Li Chengxin and the others raise sea cucumbers on the coast not for eating, but for taking advantage of the powerful ability of sea cucumbers to clean the sand and gravel at the bottom of the ocean.

For this reason, Li Chengxin also specially greeted the fishermen in the village.

In the past two years, sea urchins have become less and less, and they will be picked up by the villagers to raise them in April, so the creatures in the rocky beach area are also much more abundant.

Just on the other side of the stone where the sea cucumber was found, there were several clusters of green-mouthed clams, among which there were three or five different kinds of sea anemones.

Suddenly, the underwater robot found a big black and white fish in the barnacle bushes on the seabed.

"There are even black snapper!" Li Chengxin drooled.

Black snapper is a shallow-sea bottom fish that likes to inhabit sandy mud bottoms or rocky sea areas. It usually moves along the coastal zone with a water depth of 5-50 meters and does not migrate long distances.Omnivorous, extremely gluttonous, it mainly eats molluscs, shellfish, polychaetes, small fish and shrimps, crabs, amphipods, starfish and seaweed, and can use its tail to dig for shellfish and ring-shaped animals on the seabed.

At the same time, black snapper is also a high-grade edible fish common in fish markets in various places, and it is delicious.

The black snapper was very timid and cautious, and when it saw the underwater robot approaching, it quickly hid in the crevice of the rock.
