Marine Science and Research: Ecosystems Discovered with Bosphorus Cruise

The Bosphorus Strait is not only a cultural and historical heritage, but also a scientifically fascinating natural laboratory. This narrow waterway connecting the east and west, north and south, is also at the center of ecological boundaries and scientific discoveries. Thanks to Bosphorus Cruise tours, not only tourists but also marine scientists have the opportunity to witness the biological diversity offered by the Bosphorus.

So, are these trips just a touristic experience? Or does every boat trip on the Bosphorus open the doors to an ecosystem? In this article, we will shed light on marine science research conducted on the Bosphorus, the contribution of Bosphorus Cruise to the ecological value, and the future of this unique ecosystem.

The Bosphorus Strait: A Scientific Crossing Point

The Bosphorus is a 30-kilometer natural waterway connecting the Black Sea and the Marmara Sea. However, it represents much more than a simple crossing point. Because this narrow channel connects two different marine systems, creating a multi-layered, current-rich and biologically rich habitat.

The most interesting natural phenomenon here is the two-way current system: On the surface, there is low-salt water flowing from the Black Sea to the Marmara, and at the bottom, there is salty water moving from the Marmara to the Black Sea. This situation requires living things to adapt to different salinity levels and allows different life forms to coexist.

This turns the Bosphorus into a natural experimental field for marine biologists.

Bosphorus Cruise: From Observation Vehicle to Scientific Instruments

Traditionally, Bosphorus tours represent a historical journey from Hagia Sophia to the Maiden's Tower, from Rumeli Hisarı to Anadolu Kavağı. However, in recent years, these trips have also been used to collect scientific data.

Some universities and research institutions record living species, plankton densities, water temperature and salinity rates with sensors, water sampling devices and observation equipment integrated into these tours. In particular, projects conducted by institutions such as Istanbul University and TÜBİTAK MAM have collected a lot of data, from seawater chemistry to microplastic analysis.

This situation sets an example in terms of transforming a touristic activity into a scientific tool.

Species Discovered in the Bosphorus Ecosystem

Different life forms are frequently encountered on the Bosphorus Cruise route. For example:

• Pelagic species such as bluefish, horse mackerel and mackerel are seen in large flocks during migration seasons.
• Rare marine mammals such as the Mediterranean monk seal (Monachus monachus) and harbour porpoise (Phocoena phocoena) have occasionally been observed in the waters of the Bosphorus.
• Plankton are the cornerstones of the marine food chain. Hundreds of different plankton species have been identified in samples taken from different parts of the Bosphorus.
• Marine research analyzes the health of the ecosystem by observing the seasonal cycles of these species, their reactions to environmental changes and their adaptations caused by human influence.

Traces of Climate Change and Pollution

The Bosphorus ecosystem, unfortunately, is a mirror of not only natural but also human-induced effects. Especially in recent years, increasing marine pollution, microplastic rates and fluctuations in sea water temperature due to climate change threaten living populations.

Color changes, surface foam, and sometimes even fish deaths observed on Bosphorus Cruise tours ensure that these ecological signals are also noticed by the public.

For example, the mucilage (sea slugs) crisis in the Sea of ​​Marmara in 2021 affected the entire ecosystem, including the Bosphorus. This event was an alarming situation for marine scientists and caused many studies to accelerate.

Sustainability and Awareness: Bosphorus Cruise for the Future

The concept of ecotourism has caused Bosphorus Cruise tours to be re-evaluated. Now, some companies organize sustainability-focused tours with the concept of “conscious tourism”. In these tours:

• Speed ​​limits that will not harm marine life are observed,
• Measures are taken against the use of plastic,
• Participants are informed about the marine ecosystem.
• In addition, educational tours for children aim to develop environmental awareness in future generations. Thus, the Bosphorus is not only a place to watch, but also a heritage to be protected.

Conclusion: It is Necessary to Understand the Bosphorus, Not Just Tour It

The Bosphorus has a depth beyond the boats gliding on its surface. Every Bosphorus Cruise  is actually like passing through a nature documentary. Invisible microorganisms, fish gliding under water, silently living sponges and sea grasses… Each one tells a story.

Marine science research and the integration of this research with tourism both increase scientific awareness and carry Istanbul's natural wealth into the future. If we can realize that the Bosphorus is not just a landscape but a living ecosystem, we can take more conscious steps towards protecting it.
