There are vast oceans gathering for a feast, and people are battling the rough waves. From the Arctic to the Antarctic, the journey spans 10,000 kilometers, connecting the tropical seas to the mysterious deep sea. This extreme ocean, with a diameter of 1,600 kilometers, is both a stormy engine and a refuge for those in crisis. Humans and animals constantly challenge the dangerous and unpredictable sea in pursuit of great rewards. The Atlantic Ocean is the roughest sea on Earth. The Caribbean Sea, where sunlight brightly shines, offers a paradise of life. The shallow and warm waters provide abundant food and shelter. This is a perfect place for two-year-old Atlantic bottlenose dolphins to grow up. It is a vibrant sea, richer than any other part of the Atlantic, but living here comes at a cost.

For the next nine months, the sun's energy will push the creatures here to their limits. The paradise of the Caribbean in the Atlantic will soon turn into hell. The sun is the engine of the tropical Atlantic. The sunlight warms the sea from the African coast to the Caribbean, which is 5,000 kilometers away. In the Caribbean, there are vast, crystal-clear, shallow waters. Here, there are seagrass meadows made up of coral reefs and mangrove forests. It is a place where you can see more diverse marine life than anywhere else in the Atlantic. It is a rich habitat. February, the kindest month in the Caribbean. However, the waters of the Bahamas are warm, and the water is filled with various sounds. The dolphins of the Atlantic chat away. This is a safe haven. In the deeper waters, sharks roam around, while the highly social dolphins...

Dolphins live in groups and play and hunt together. The calves are still nursing and their spots have not fully developed yet. During this time, the young dolphins must learn the necessary skills for social life. They need to learn complex clicking sounds and whistles. Language is also important. By playfully biting each other, they learn to interact and build bonds with one another. They also engage in

I live in a place where the temperature of the water does not drop below 20 degrees Celsius due to the low fat content. If the water temperature drops below 20 degrees, they will die. Most of the actors spend the winter in warm rivers. As the water temperature rises, they are now scattered along the Caribou Sea, searching for their favorite food, seaweed. Seaweed covers a large part of the ocean, and it grows faster as the flesh becomes stronger. Over the next few months, they will graze on underwater meadows for hours each day. For now, this place is a sanctuary for them, but changes are about to happen. In April, it will become stronger. Small changes can have a significant impact. With the rise in water temperature, a spectacular scene unfolds every year in the deep waters beyond the Belize coral reef reserve. There is one reason why they gather in a specific place for about an hour. Water drums usually travel alone and live in depths exceeding 20 meters. However, as the water temperature rises...

As the days lengthen and the awaited moon appears, the witch Mary gathers water. At dusk, the fish rise to the surface to spawn. The females lay eggs while the males release sperm. Spawning occurs at this time to evade the eyes of predators. However, it is not always perfectly successful. The whale shark, which grows to the size and weight of a two-story building, does not target fish. Sharks can filter in tens of thousands of gallons of water at once. Millions of eggs are sacrificed, but many more survive. The young will be carried by the currents to safe places. The mangrove forests along the Caribbean Sea hold a secret. They are an incredible refuge beneath the water.

This region's temperature in May is close to 40 degrees. This intense heat fuels strong winds that blow from the desert towards the Atlantic Ocean in the west. The trade winds first reach the Cape Verde Islands, located 650 kilometers off the coast of Africa. These trade winds dominate the barren islands. The people here live in close connection with both the wind and the sea. They create their livelihoods through traditional means. The fishermen, led by the wind, are well attuned to its patterns. The wind is a crucial factor for both successful fishing and disasters. They venture far out to catch fish, with trips sometimes taking over a week. The fishermen depend on the wind; if it fails them, they may not return. After successfully completing their fishing trips, the fishermen head home, but the trade winds continue to race westward across the ocean.

The trade winds, while moving, absorb moisture rising from the sea. In May, due to the intense sunlight, billions of tons of water evaporate from the surface of the ocean every day. The trade winds sweep the clouds formed in this way toward the west. Finally, upon reaching the paradise of the Caribbean, the trade winds deliver the much-needed resource: rain. The rainwater flows over the land and is swept into the sea. The roots of the mangrove trees slow down the current, allowing sediment to settle. This sediment provides nutrients to the mangrove forest. The tree roots act as filters, keeping the waters of the Caribbean crystal clear. As June arrives, the sun's power reaches its peak. In the scorching heat, the clouds vanish. Now, in this sea, many creatures will experience extreme living conditions due to the intense heat. But for now, everything is just perfect.

It is calm in the waters off the Bahamas, where juvenile dolphins have formed a group. The appearance of spots is a signal that it is time for them to become independent. They must now hunt for themselves. For dolphins, hunting is a cooperative effort. They have driven a fish into a corner, but they are not trying to eat it. The dolphins communicate by creating strong waves and take turns herding the fish. Through play, they learn to synchronize their movements and work as a team. Fortunately, it seems the dolphins have become bored. Cooperation skills are extremely important for their survival. In the summer, with the heat and light of the sun, plants increase explosively. Seagrass can grow up to 3 cm a day, which is great news for the dolphins. There are also dense patches of algae growing on the surface. There is not far to go to find a place to clean themselves.

Young sea slugs provide cleaning services next to the coral reef. The wrasse gets its food, and thanks to this, it becomes clean. Now, the wrasse returns to its important task of feeding. The tropical sun breathes life into various places. In the Bahamas, there are animals that love the sunlight. Although they may look slow, the Cassiopea jellyfish is hurrying somewhere. It is on its way to a sunbathing party. Every day, hundreds of jellyfish gather in calm waters and good spots. Their source of energy is the sun. Under the tentacles of the Cassiopea jellyfish, there are zooxanthellae that perform photosynthesis by capturing sunlight. The nutrients produced in this process become food for the jellyfish. It is a mutually beneficial exchange. The jellyfish get free food in return for seeking sunlight and becoming a mobile greenhouse for the zooxanthellae.

When the sun shines and the currents are present, jellyfish have very little to hunt. As the sun sets, jellyfish take a break for the sunbathing of the next day. In the evening, the sun loses its strength, but during this time, its power continues until night. After darkness falls, the mangrove lagoon transforms like magic. Clifford, a fisherman from Belize, plans to catch fish during this time. Underwater creatures that have diligently stored solar energy throughout the day are now ready to release that energy. Fish swim around, putting on a light show. In fact, it is not the fish that emit light, but much smaller organisms. These are dinoflagellates, single-celled organisms that thrive in the warm, nutrient-rich waters of the mangrove forest. When they start to stir, they light up.

Bioluminescence is a means of evading predators. Since they are charged by sunlight, the longer the day, the stronger the light becomes. The light is so strong that Clifford can catch fish even in the middle of the night. When night falls, a different spectacle unfolds in the coral reef areas, even further away from the boat. It signals that the ecosystem of the coral reef is overheating under the summer sun. It may not look like coral, but it is coral. Scientists believe that the light emitted by coral acts like a sunscreen. Coral lives in symbiosis with zooxanthellae, which create food for the coral through photosynthesis. However, excessive exposure to ultraviolet light poses a danger, and the coral has developed a defense mechanism. Special proteins absorb ultraviolet light and re-emit it as different wavelengths. During the day, the sunlight is too bright for that light to...

Although they are not visible, at night, the mountains display a brilliant fluorescent light, indicating their response to ultraviolet rays. In the sweltering summer, this is a crucial defense mechanism for the mountains, especially when there is no way to escape the sun. In August, the temperature in Suwon rose to 29 degrees Celsius, prompting many animals to seek refuge in the shade. On Grand Cayman Island, millions of juvenile fish gather in coral reefs and caves. Staying in groups is a safety measure; however, dangers lurk in the dark caves. One such danger is a predator that can grow as long as a person and possesses a terrifying appetite. It has explosive acceleration capabilities and can sprint at speeds of 60 kilometers per hour. When it attacks, the empty space in its jaw creates a suction effect, allowing it to swallow its prey whole. More juvenile fish are gathering inside the cave.

As the number of tarps increases, we cannot miss the festival that only happens around this time. The ocean is getting hotter, and the places where dolphins live are also warming up. A young dolphin tried not to separate from its mother because a male dolphin had discovered her and was persistently chasing after them. The act of flipping its body and blowing bubbles is a signal that the male is excited, but the mother shows no interest. Avoiding one male dolphin is not difficult, but evading a group of cooperating males is a different challenge. Males from another group are searching for a mate. This team constantly communicates with each other, targeting solitary females. Even if the females try to escape, the males do not give up. They push the females down and use ultrasound to determine if they are ready to breed. They want to mate with the females and compete with rivals.

Water is always ready to fight, and the groups shout at each other loudly enough to become deaf. Usually, this sound is made for unity, but now it has become a threatening weapon. Putting their heads together and opening their mouths is also an aggressive act. This clash could escalate into violence, but this time, the disruptor steps back. The young learn everything by observing. The world of dolphins is more dangerous than one might think. At the end of the month, it is hotter than ever. The creatures living in the coral reef area struggle to withstand the rising heat. Corals are very sensitive. Even a 1-degree increase in summer water temperature can lead to devastating results. When the water heats up, corals expel the symbiotic algae that provide them with food. Corals that release the algae that used to nourish them turn completely white within a few days. If the heat persists for too long, corals...

Survival is not possible. Animals that relied on coral are losing their food and habitat. The sun, which was once the driving force of life, is now destroying it. The fate of the entire tropical Atlantic is in a precarious moment. Five thousand kilometers to the east, the power of the ocean begins to stir. 

In the Cape Verde Islands of Africa, the hot winds brought from the Sahara Desert cause the sea to churn violently. The fishing conditions are changing; the warm waters are creating moisture, intensifying the trade winds. It is a dangerous situation. A decision must be made. He knows what is approaching: a tropical storm is brewing. All fishing boats have evacuated. The storm is carried quickly by the trade winds, heading towards the open sea. As the storm moves, it can grow tremendously in size. A chain reaction begins, as hot water and wind combine.

Convection currents are continuously occurring. Warm air rises from the ocean, drawing moisture upward and forming massive cloud layers. More air is sucked in from below, and whirlwinds begin to appear. The storm continues to gain strength as it races over the ocean. When wind speeds reach 120 km/h, the tropical storm acquires a new name. The hurricane, an unstoppable force of nature, heads toward the Caribbean, and the countdown to destruction has begun. Animals and corals, pushed to the brink by suffocating heat, will soon face a lethal assault. The warm ocean, which once nurtured life, has become the fuel for a storm that threatens it. Everything is about to change. Thirty-six hours before the hurricane's arrival, the first signs appear. Giant waves rise in the once calm sea, and a hurricane warning is issued.

The wind speed upon arrival exceeds 90 km/h, and dolphins retreat to deeper waters. To survive, they must gather together. This is a moment when their communication abilities shine. Those who are unable to evacuate in time on land must find a safe place to hide and wait. Twelve hours before landfall, a massive storm accompanied by thunder approaches the harbor. Now, gusts of wind exceeding 110 km/h are raging. Giant waves, driven by the wind, crash against the coastline with terrifying force. The sea is entirely turbulent, with speeds reaching 200 km/h. The relentless power of the sun has transformed paradise into hell. Hurricanes are the most destructive forces of nature. On land, property is destroyed by hurricanes, but people can evacuate. However, for marine animals, there is nowhere to hide. Dolphins that become separated from their pods due to the hurricane can be in danger.

There are young sharks alone that are easy prey. The mangrove forest has taken a direct hit from the storm. The wind has stirred up the sediment, and the murky water appears lifeless. However, the tree roots create a safe refuge. The creatures seek safety deep within the mangrove forest during the hurricane. The trees act as living shock absorbers. The tree roots are the best breakwaters that effectively disperse destructive energy. The mangrove forest calms the incoming waves and serves as a storm shelter in the Caribbean. The tree roots protect the nursery grounds of young fish and slow down the water flow, allowing sediments to settle, which clears the water. The mangrove forest not only protects against hurricanes.

Hurricanes are also utilized. Storm surges widely spread the mangrove seedlings, allowing young trees to take root in the gaps of the forest. The tropical Atlantic's refuge will continue to grow. In the coral reef areas, hurricanes have calmed the overheated ecosystems. Some parts of the coral were damaged, but thanks to the bays, the water levels decreased. Corals will once again accept the currents, and the coral reef ecosystem will recover. Hurricanes are known to cause significant harm to the pods of dolphins off the coast of Nammal. The only way for a stranded young dolphin to survive is to reunite with its pod. Nature knows how to recover. Research by scientists shows that in pods that have lost their young, the female dolphins will give birth more frequently than usual. This will strengthen the bonds within the pod.

The life in the tropical Atlantic, which had been temporarily paused, begins again. Paradise is peaceful now, but it will soon start to heat up again. The sun grants opportunities for life but also brings destruction. The lives of various species coexist in this amazing wild sea where extremes meet.
