Object of study: Plants and plant communities of aquatic ecosystems (aquatic and coastal-aquatic). Research methods: field (geobotanical descriptions), remote and laboratory analyzes (determination of physiological and biochemical status and spectral indices of dew removed from contaminated territories). Purpose of work: development of information technologies for monitoring the ecological status of vetlands (wetlands) in real time, taking into account the pollution of the environment with heavy metals and petroleum products on the basis of determining the system of persistent identification features of technogenic pollution of water bodies by the results of terrestrial spectrometry of water vegetation, calculated by satellite data, and physiological-biochemical analysis of hydrophytes growing in reservoirs with contaminated with petroleum products and heavy metal ions. During the reporting period, two different wetland test sites were selected in the area adjacent to the Bortnitsky Aeration Station. It was found that the content of nitrogen and phosphorus in water is more than 10 times higher in the contaminated area, and the concentration of Mn, Cr, Cu, Co and Pb in the soil exceeds the corresponding indicator of the pure area. Carex riparia and Phragmites australis were selected to test for contamination levels. Seasonal dynamics of morphometric parameters, leaf respiration, photosynthesis, chlorophyll a fluorescence induction parameters, photosynthetic pigment content and 15 spectral vegetation indices (VI) were determined. Carex riparia plants from the contaminated area were characterized by earlier onset and termination of vegetation and Phragmites australis by faster growth. Indicators of leaf respiration in plants from the "contaminated" area were lower compared to "clean". As of 06/20/2019, a reduced content of the amount of chlorophylls a and b and carotenoids in Carex riparia and Phragmites australis plants in the contaminated area was registered. It is established that the highest correlation between the VI calculated according to the data of the ASD FieldSpec 3FR spectroradiometer and the UAV-mounted Ocean Optics STS-VIS spectrometer is inherent in NDRE1, NDRE2, NDVI1 (800, 670), GNDVI, PSRI, SR; the average correlation is characteristic of CIgreen, CIrededge, NDVI2 (780,740), SAVI, EVI2, ZM. It was found that during the spring and summer vegetation, greater differences between the values of VI, depending on the ecological state of the place of growth, were characteristic of coastal sediments than of the southern reeds. The "contaminated" area was characterized by lower values of VI, compared to the "clean" one. During the reporting period, 1 article was published and 1 article was published.

Saving a scientific data set occurs in two stages:
1.) Creating a data set
Enter the name of the set, a brief description of the set (annotation), and click the “Create set” button. After that, a draft data set will be automatically created, which you can save for further work with the set. The system will redirect you to the “Data set information” page.
2.) Filling in the data
On the “Data set information” page, you need to fill in all the fields related to the data set and upload the files.
Please note! Each file is uploaded separately. This is done to ensure the stable operation of the system.
Once you have filled in the information about the scientific data set and added the necessary files, you can save the draft or send the data to the system.
Please note! Once the data has been sent, you cannot change it.
Drafts are necessary for storing the data set and editing it before sending.
All accounts on the NRA website go through a standard registration procedure and are verified. However, in order to obtain additional features, such as publishing open reviews of academic texts, verification by affiliation is required.
To obtain the status “verified”, you must change your primary email address to a corporate one, which is tied to a scientific or educational institution.
For example: user@ukrintei.ua, user@nas.gov.ua
After confirming your corporate email address, your account will be automatically verified by affiliation.
If your email address is corporate, but your account does not have a verification mark, you need to write to us at the email address NRAT@ukrintei.ua. After verification, we will add your address to the database, and your account will be verified.
After completing the verification procedure for affiliation, you can change the primary email address to a convenient one for you, without losing your status during the current verification.
You only need to verify for affiliation once.
* We use corporate addresses from the Unified State Database on Education and the State Register of Scientific Institutions Supported by the State
To search for news published on the official website of NRАT in the “News” section, you need to enter one word, several words, or an exact phrase in the search field. Different terms are separated by spaces.
The search is performed everywhere – in the title and the news text.
For a more comprehensive result, it is recommended to use word stems (parts of words without endings).
When using multiple words for the search, they are combined using one of the logical methods described below.
By default, the logical connector “and” is used. In this case, search results will include all news releases that contain the specified words, even if they are located separately from each other and are in different parts of the text.
Example: Search phrase: OECD report. Search result: all news containing the words “report” and “OECD” in the text and in the title, both together and separately.
If a phrase or phrase is enclosed in quotation marks (“), the results will include all publications where this exact phrase or phrase is found.
Example: Search phrase: “OECD report.” Search result: all news containing the exact phrase “OECD report.”
If you know the publication date of the news or are interested in a specific time frame in which they were published on the website, you can select such a date or date range in the additional field that looks like a calendar. The date is entered in the format year-month-day and confirmed by clicking on the corresponding date in the calendar dropdown. You can enter a date or choose one by browsing through the calendar by months and years. By default, the interval starts from the oldest date (2018-01-23) and ends with the current date.
You can also use one or more hashtags, which are located under the search field on the right side of the “News” page.
Please note: The search for academic texts is carried out in a separate search window at the following link https://nrat.ukrintei.ua/searchdb.
