Phytoplankton Research
Aboard the SilverLining, the University of Brussels (Vrije Universiteit Brussel - VUB) will conduct research on Phytoplankton.
​
Phytoplankton, microscopic plant-like organisms that live near the surface of the ocean, are one of the most important components of marine ecosystems. They serve as the base of the food web, provide oxygen through photosynthesis, and remove significant amounts of carbon dioxide from the atmosphere. In this section, we will explore the identification and mobilization of nutrients for phytoplankton in the oceans, and more particularly in the Pacific Ocean, and the importance of phytoplankton in the fish stock and the capturing CO2 and the resulting impact on global warming.
The importance of Phytoplankton for our ecosystem
Identification of Nutrients for Phytoplankton.
Phytoplankton require sunlight and a range of nutrients to grow and multiply, including nitrogen, phosphorus, and silica. However, the availability of these nutrients can vary widely throughout the world's oceans, with some areas being nutrient-rich, while others are nutrient-poor. In the Pacific Ocean, for example, the eastern side of the ocean is generally nutrient-poor, while the western side is nutrient-rich, with large blooms of phytoplankton occurring during certain times of the year.
The identification of nutrient-rich areas in the ocean's water column is critical for understanding and predicting the growth and distribution of phytoplankton. Researchers use various methods to identify nutrient-rich areas, including remote sensing techniques, such as satellite imagery, and in situ measurements, such as water sampling and analysis.
Mobilization of Nutrients for Phytoplankton
Once identified, the mobilization of nutrients for phytoplankton involves a complex interplay between physical, chemical, and biological processes. For example, upwelling, the process by which cold, nutrient-rich water rises to the surface, can result in the formation of phytoplankton blooms in otherwise nutrient-poor regions. Additionally, seasonal changes in wind patterns, currents, and weather conditions can also affect the distribution and availability of nutrients.
The Importance of Phytoplankton in Capturing CO2
One of the most critical functions of phytoplankton is their ability to capture carbon dioxide (CO2) through photosynthesis. This process plays an essential role in regulating the Earth's climate by removing CO2 from the atmosphere and transferring it to the deep ocean. Without phytoplankton, the Earth's climate would be significantly different, as atmospheric CO2 levels would be much higher, resulting in even more significant amounts of global warming.
The impact of increasing CO2 levels on the Earth's climate has been a major concern in recent years. The increase in atmospheric CO2 levels due to human activities, such as burning fossil fuels and deforestation, has led to a rise in global temperatures, causing a range of environmental problems, including sea level rise, ocean acidification, and changes in weather patterns.
Conclusion
Phytoplankton are crucial to marine ecosystems and play also an essential role in regulating the Earth's climate. The identification and mobilization of nutrients for phytoplankton in the Pacific Ocean are critical to understanding and predicting their growth and distribution. As such, continued research into the identification and mobilization of nutrients for phytoplankton is vital for the health of our oceans and the planet as a whole.
