In this study we have analyzed whether tourist cruise ships have an influence on measured sulfur dioxide (SO2), ozone (O3), Aitken mode particle and equivalent black carbon (EBC) concentrations at Ny Ålesund and Zeppelin Mountain on Svalbard in the Norwegian Arctic during summer. We separated the measurement data set into periods when ships were present and periods when ships were not present i...

Reliable ship detection plays an important role in both military and civil fields. However, it makes the task difficult with high-resolution remote sensing images with complex background and various types of ships with different poses, shapes and scales. Related works mostly used gray and shape features to detect ships, which obtain results with poor robustness and efficiency. To detect ships m...

Repeated ocean ambient noise measurements at a shallow water (110 m) site near San Clemente Island reveal little increase in noise levels in the absence of local ships. Navy reports document ambient noise levels at this site in 1958-1959 and 1963-1964 and a seafloor recorder documents noise during 2005-2006. When noise from local ships was excluded from the 2005-2006 recordings, median sound le...

BACKGROUND Most of the scientific publications from the maritime area are studies about the mortality and morbidity, while studies about the present hazards of potentially dangerous exposures are relatively rare. AIMS To describe the seafarers' assessments of the occupational safety on board, their exposure to chemicals and the use of personal protection equipment and to identify the areas fo...

Anomalies are the source of all scientific investigation and discovery. The mysterious disappearance of ships at sea has long been recognized as a standard type of anomaly. A new theory proposes that the catastrophic release of giant methane bubbles from the ocean floor can possibly account for the disappearance of some ships. The theory is both novel and plausible. However it has limited appli...

SDU var vært for årets LIBER-konference, der havde deltagelse af omkring 400 deltagere fra hele Europa, som diskuterede og delte tanker om åbenhed, verdensmål, internationalt samarbejde – meget mere.

J ust after midnight on March 24, 1989, the giant oil tanker Exxon Valdez ran aground on Bligh Reef off the coast of Alaska, spilling almost 21 million gallons of crude oil into the sea. The disaster caused an oil slick that covered 3,000 square miles and contaminated 1,090 miles of coastline along the pristine Prince William Sound, killing thousands of marine creatures and costing Exxon $1.28 ...
