Variability in the ocean environment can greatly impact acoustic propagation. Sonar systems often show large performance differences depending on location and oceanographic conditions. The long term goals of this research is to better understand the fundamental environmental quantities that impact shallow water acoustic propagation and to develop techniques for both characterizing the environme...

Interdisciplinary global ocean science requires new ways of thinking about data and data management. With new data policies and growing technological capabilities, datasets of increasing variety and complexity are being made available digitally and data management is coming to be recognized as an integral part of scientific research. To meet the changing expectations of scientists collecting da...

The oceanographic conditions in the north Pacific have shifted to a colder period, Pacific sardine (Sardinops sagax) biomass has declined precipitously in the California Current, the international sardine fishery is collapsing, and mackerel (Trachurus symmetricus and Scomber japonicus) are thriving. This situation occurred in the mid-1900s, but indices of current oceanographic conditions and th...

The purpose of this work is to analyze long-term changes in oceanographic indicators the southeastern area northwestern Black Sea November-December 2000–2021, which determine migration activity and fishery performance hammerhead off coast Crimea. Materials methods used: statistics, data information system Copernicus Marine Service satellite altimetry surface temperature waters near western Crim...

The accumulation of floating marine litter poses a serious threat to the global environment and economy all over world, particularly coastal municipalities that rely on tourism recreational activities. Data is thus crucial, but usually limited, can be complemented with modelling results. In this study, operational system Algarve (SOMA) was combined Lagrangian particle-tracking model blended sca...

An automatic measuring system called FerryBox was installed on a ferry travelling between Cuxhaven (Germany) and Harwich (Great Britain) enabling on-line oceanographic and biological measurements such as salinity, temperature, fluorescence, turbidity, oxygen, pH, and nutrient concentrations. The high frequent sampling of data allows to detect even short-term events. Observations made along the ...

The zooplankton community and environmental conditions were monitored during Dec. 2012 PG-GOOS (Persian Gulf and Gulf of Oman Oceanographic Study) oceanographic cruise on board N/V Ja Nayband throughout the northwestern part of the Persian Gulf. Data of temperature, salinity, depth and pH as well as zooplankton community composition and abundance were collected from 17 stations. The zoopla...
