This paper answers the question of why there are ripples on the 4000-meter deep seabed, introduces the definition and geological significance of ripples, and explains that shallow sea ripples are formed by sea surface waves stirring up sediment. Through the HEBBLE Deep Sea Observation Program, scientists discovered that the flow along the isobath is the cause of deep sea ripples. At the same time, the program also observed the phenomenon of deep sea storms. The discovery of deep sea currents has changed people's understanding of the deep sea environment.

Focusing on the question of "Is there only waves on the sea surface?" This paper introduces the causes and characteristics of waves on the sea surface, explains the formation mechanism, discovery process, power characteristics, observation methods of internal waves in the ocean, and their importance in the marine ecology and military fields. role.

Focusing on the question of "Do El Niño events have 'twin sisters'", this paper introduces the meaning of the La Niño event, its connection with El Niño, its climate characteristics, and the global climate impact when the La Niña event occurred, and takes the 2008 La Niña event triggered by the multi-regional disaster situation as an example to illustrate.

Based on the connection between the severe floods in the Yangtze, Songhua and Nenjiang basins in China in 1998 and the strongest El Niño phenomenon in 1997 in a century, this paper introduces the impact, formation mechanism, name origin and occurrence cycle of the El Niño phenomenon, and explains why the El Niño event in the eastern Pacific originated in the western Pacific.

This paper answers the question of where the water is hottest on the surface of the tropical ocean, introduces the basic characteristics such as temperature, area, and scope of the oceanic warm pool located in the tropical western Pacific and the eastern Indian Ocean, and takes the Pacific Ocean as an example to explain the formation of the oceanic warm pool. It also explains its impact on climate and natural disasters in Asia, the Pacific and even the world.

This paper focuses on the question of where the salt in seawater comes from. It introduces that when the ocean was first formed, the salt content was much lower than it is now. The seawater gradually becomes salty after a long period of evolution. On the one hand, the salt comes from the accumulation of salt brought into the ocean by surface runoff scouring land rocks for a long time. On the other hand, there is a view that part of the salt comes from components released to the surface in the form of gas deep in the earth's crust. For example, sodium chloride vapor, which accounts for 50.29% to 76.01% of all sublimated substances, can enter the ocean through various channels.

Focusing on the question of "Why is the Dead Sea called the Dead Sea when people cannot drown?" This article introduces the geographical location and desolate and inanimate environmental characteristics of the Dead Sea, explains the reason why it is named "Dead Sea" because of high salinity resulting in almost no living things. It explains the principle that the Dead Sea cannot drown people and the irritation of high-salt seawater to the human body. It also tells the historical origin of the Dead Sea being called "Sea".

Aiming at the question of "why is the sea water salty but the sea ice light", this paper introduces that sea ice is a general term for ice in the sea, including two types of ice directly frozen by sea water and ice coming from land, and explains the reasons for the low salinity of the two types of sea ice.

This paper takes the question of whether the seawater of the Yellow Sea, Red Sea, Black Sea, and White Sea is really the corresponding color as the starting point, and introduces the geographical location, hydrological characteristics and specific reasons for presenting the corresponding name colors of the four sea areas.

This paper focuses on the question of "why is the sea blue and the waves white", from the composition of sunlight, the optical effects such as absorption, scattering, and refraction of light of different wavelengths in the sea and waves, and the photosensitive characteristics of the human eye. Explanation is made in terms of aspects.

This article focuses on the theme of sea water and its movement

Focusing on the question of where the largest ocean in the solar system is, this paper points out that Europa (Europa) may have the largest ocean in the solar system. It introduces relevant observational and theoretical evidence, the heat source mechanism of Europa's liquid ocean, and scientists 'exploration assumptions and speculation that simple life may exist in the ocean.
