“…A partir dos diversos bancos descritos aqui, foram disponibilizadas 1442 séries de dados de 996 boias de deriva. Todos os derivadores utilizados são do modelo padrão WOCE (Sybrandy et al, 1992 Os dados foram tratados temporalmente para o intervalo total do período de dados disponíveis, isto é, entre 01/11/1989 e 02/06/2007. Dessa forma, os resultados encontrados referem-se ao período global, e não às variações sazonais.…”

“…They were based on the application of LOBAN (light one-time buoy with automatic navigation) floats equipped with special devices for transferring the data of measurements and determining the location of buoys via the COSPAS-SARSAT Doppler satellite system (Space System for Searching Vessels in Distress-Searchand-Rescue Satellite-Aiding Tracking) [2,3]. Since 1999, the program of long-term drifter monitoring is realized in the Black-Sea region by using the so-called WOCE drifter technology [4] based on the application of drifters with spherical floats and vertically oriented cylindrical drogues [5,6]. The data transfer is realized via the Argos satellite-based location-and-data collection system [7].…”

The autonomous drifting buoys equipped with satellite link turn into one of the most important components of the global system of operative observations of the ocean and the surface layer of the atmosphere. However, on the regional level, the problem of analysis of the surface circulation of waters in the coastal zone and sea straits remains quite urgent because the available drifters cannot be used in this case due to their sizes and long intervals between measurements. We present the results of development and testing of a new drifter system aimed at measuring currents. The system is based on the use of buoys operating at depths less than 1 m. To improve the space-and-time resolution of measurements, the buoys are equipped with receivers of the global positioning system (GPS) and GSM modems for the data transfer via cellular communication networks. The drifter system guarantees the possibility of determination of the coordinates of buoys with a resolution of 3 min in time and 14 m in space. We describe the specific features of the design of the proposed information-and-measuring drifter system and present the first results of application of new buoys called "minidrifters" for the pilot monitoring of currents in the Kerch Strait.

“…Drifting buoys for collecting marine data are increasingly widely used for investigation, forecasting and disaster prevention, resource management, and marine environmental protection [5,6] because there are many preeminent features of drifting buoys that other marine data collection devices do not have, which are: Drifting in the water stream, simultaneously measuring many oceanographic factors (waves, temperature, salinity, currents, etc. ), can be used for many buoys for specific locations, creating the mobile station arrays of drifting buoys.…”

This paper presents the primary contents of successfully researching, designing and manufacturing drifting buoys to collect marine data to measure temperature, salinity, and ocean currents in surface layers. The paper presents the basic information about the structure, specifications, the buoys working as the laboratory results, and field tests of drift buoys at sea. The drifting buoy test results at the sea of Van Don - Quang Ninh area met the criteria of water-tightness, buoyancy, and balance; the ability to collect temperature and salinity data of the sensors; the ability to transmit and receive information from drifting buoy at sea to the central computer via a web server; operability of the parachute and the travel of the buoy. The buoy database management software is on the website at http://vnsea.vn. It manages the collected data in real-time, showing the parameters and their variables in space and time, the buoy's tracking on the Google map.
