Baza dannyh nablyudeniy vnutrennih voln v Mirovom okeane

Abstract

Purpose. The purpose of the paper is to describe the permanently updated public database containing the information on observations of the internal waves, as well as the scientific sources on the corresponding themes. The observations are based on the data obtained by remote sensing and direct contact measurements in various areas of the World Ocean and in the inland basins (lakes, reservoirs). Methods and Results. The data from 503 literature sources on the observations of internal waves are structured. The structure, format, volume and current content of the database are considered; the stored information is analyzed. Described is the process of adding and viewing the records using the IGWAtlas web application (the online project for working with the database of the observations of internal waves in the oceans and for public access to observations and sources that has an intuitive user interface). Geographical distribution of the recorded observations and their dependence on a season are illustrated. The examples of images of various types of records contained in the database, as well as their distribution according to the types of observations are given. The considered in the paper database is integrated into the IGWResearch software package intended for numerical simulation of propagation and transformation of the internal waves in the World Ocean. Conclusions. The database contains the materials for 1972–2018 on 2296 recorded manifestations of the internal waves, which correspond to 2465 images, namely device records, satellite images, graphs, maps and tables. The database scope includes geographic information systems, statistical analysis, knowledge bases, web-services for the tasks of the World Ocean research.
