Under the patronage of the presidency, under the responsibility of the Ministry of Industry and Technology and the Coordination of Tubitak Mam Pole Research Institute, the 5th national scientific research expedition, sea water, sediment, sea ice and glacier analyzes, which from CTD devices from CTD division from the region, which in the regions in the regions with stronger Regions, in the region, in the regions, in the region, in the region, in the regions, in the regions, in the region, in the regions, in the regions, in the region, in the areas of temperatures and salt content in the areas of saline acids, in national times, into the national. is.
As part of Edna, the genetic scars of the living species living in the region are monitored and aims to monitor the changes in the ecosystem at a biological level. The collected samples are assessed with data such as chlorophyll, organic substance, nutrient salts and physical measurements carried out by CTD devices.
Studies contribute to persecution of large environmental changes, such as the progress of Atlantic waters in the north and the spread of boreal species to the Arctic. This integrated approach offers a holistic evaluation of the effects of climate change on the ecosystem.
“With the melting of the sea ice, we actually show how much the sea ecosystem was influenced by it.”
5. National Arctic Scientific Research Expedition Assoc. Dr. Erhan Arslan, guest researcher who took part in the expedition, recommended Turkish researchers to work together, he said.
Assoc. Dr. Arslan: “For example, we are currently examining data such as conductivity, salt shakers and temperature distribution from different depths in our CTD measurements. In these surveillance projects we show how much the sea ecosystem is influenced by the melting of the sea ice. They transform them into a better surveillance project,” he said.
The Institute for Navy Sciences at Naval East Technical University (MetU), Doctoral Education and Participant Bilge Durgut this year, this year as part of the national arctic scientific research expedition (TAT-V) ARCTIC towards intelligent biodiversity after “working of the first systematic surveillance attempts in Türkiye.
Durgut, last year at the expedition of the sea of Barents and Svalbard, sediment, sea ice and glacier melting samples by transferring examples this year by using the example of the same stations to follow the changes in time, he said.
Durgut, who announced that they collect environmental DNA samples from the sea water called Edna, said: “Environment -DNA actually expresses the genetic material that was left by living things in their environment. In these environment -DNA examples we collect various examples such as chlorophyll, particle -organic substances, nutritional salt and phytoplon. CTD data. ” he said.
Durgut, sediment, sea ice and glacier examples for EDNA analyzes through expression, so that both eukaryotic and prokaryotic communities and the region's biojeochemical properties tried to understand them.
One of the main objectives of the study is to follow the biological traces of major environmental changes such as the progression of Atlantic waters, which are called Atlantification on the Arctic, and the spread of boreal species, which are called north of the boreal species.
“This monitoring study, in which the oceanographic and bioguechemical data is integrated into molecular biological methods, is crucial to monitor the effects of these transformations on ecosystems and to analyze the effects of climate change in the ecosystem level.
“We measure temperature, salinity and density values in different water depths”
Dokuz Eylül University Institute of Marine Sciences and Technology Assoc. Dr.
Nasif emphasizes that the Arctic region is one of the first and most powerful places of climate change, and said: “The melting of the ice can completely change the structure of the water column. He said.
Assoc. Dr. Nasıf explained that the CTD project has become a surveillance project and said:
“For 2 years, when we return to the same points and every time we approach one step closer to understanding what nature says to us. We are here.”
Nasif found that the CTD method is a frequent measurement value used by many disciplines in marine sciences, and said he used it for changes in the hydrographic layer of water in the water layer.
Nasıf said that other scientists, biologists and chemists who carry out measurements here want to know which part of the water branch from which temperature and salt content they receive, and that this measurement can be used in many disciplines.
