For centuries, fishermen and divers have used the changing colors of ocean water to predict weather and storms. Now, for the first time, scientific research has proven that the changing colors of the oceans also reflect environmental changes.

Global climate change and global warming have caused irreparable damage to ocean ecosystems and marine life. According to a study published in the Royal Anthropological Institute in late July, there have been major changes in the color of oceans around the world over the past decade. One of the main reasons for these changes is the increase in global temperature.

In 2015, she was affiliated with Syracuse University in New York, according to Christine Malone Andrews, author of a study published in the Royal Anthropological Institute in July 2023. In connection with research, he had the opportunity to observe the water problems in the Dominican Republic and stay for some time.

During this time, he also tried to understand the metaphors of divers. She explains that divers generally used black, yellow, blue, green, brown, and chocolate colors to describe the condition of the seawater in different conditions. According to Malone Andrews, these changing colors gave divers important information about water depth, currents, turbidity, storm surges, and the presence of fish. Along with this, they found that the effects of environmental changes are also affecting the oceans due to which their color is changing.

Malone was inspired by this information and started new research. She wanted to know if the changing colors of the oceans reflect climate change and if they could be used to develop a model to help save ocean ecosystems. According to Malone, when he shared the idea with Tim Edensor, a lecturer in the Department of Social and Cultural Geography at Manchester Metropolitan University, Edensor expressed extraordinary interest.

According to Malone Andrews, the seven colors of the rainbow are an important part of our life and environment, which help to understand the culture and socio-political life of different regions and have been the focus of special attention of anthropologists. However due to environmental changes, these colors of nature have started to fade, so big changes have been noted in many places, including the oceans. According to Malone, the focus of his research was on communities, whose effects of climate change on social and community life are significant and dangerous. She says that the changes in the color of the ocean are disturbing because they are directly affecting marine life and coastal communities.

According to Christine Malone, fishermen in the Dominican Republic have been noticing changes in the color and condition of the seawater for a long time. Due to the increase in global temperature, the color of the ocean has turned yellowish white, due to which fish and other aquatic life have moved into deeper water because the yellow color is lethal to them.

She says that earlier the water used to be chocolate brown for a few weeks after a hurricane, but now this period has increased to several months. These colors have negative effects on both the vision and physical health of divers. According to Malone, in the recent past, purple used to mean transparent sea water, but now this color of water has also become rare around the world.

She further explains that the analysis of these changing colors of seawater has given scientists and researchers important information about marine ecosystems, which will also help in making new global environmental policies in the future. Some time ago, a study was published by the Department of Atmospheric and Planetary Sciences of the Massachusetts Institute of Technology, which was supported by data obtained from the Aqua satellite. Launched in the year 2002, this satellite has been observing changes in the color and state of the ocean for the past 22 years. This satellite analyzes seawater in a full spectrum, or band of seven colors, including the distinctive blue hue that the oceans typically see.

According to the study, 56 percent of the world's oceans have changed color, most of which are in tropical regions near the equator, where temperatures have increased rapidly. Further analysis of this data revealed that these apparent variations in color are due to climate change and global warming. "It's no secret that our oceans are changing, and the changes in their colors show that the communities of phytoplankton," the unit of the marine food chain, are changing, says Stephanie Ditkevy, a scientist who assisted in the study. Human heads are severely affected by summer.

This is an alarming situation, she says, because the impact of phytoplankton has a direct impact on the oceans' ability to absorb carbon. Although oceans are essential for human survival, this is a change that cannot be reversed by humans.

Pakistan's coastline is also suffering from severe water pollution and other problems. Deutsche Welle contacted several experts in marine sciences to find out about any such research or activity on the Pakistani coastline but could not get any substantial response.
