What will some 4,000 of the smartest dressed elephant seals, tuna fish, albatrosses, leatherback sea turtles, great white sharks, and other pelagic megafauna in the Pacific all be wearing in the coming seasons? How about the latest in microprocessor-based electronic tags, some no bigger than oversized cufflinks? Its all in a continuing effort to understand the habits of marine animals in that part of the world: what exactly lives where and why, what their migration routes and diving behaviors might be, and what might be going on in the ocean all around them – temperature, salinity and other physical data.
Its called the TOPP program – Tagging of the Pacific Pelagics – and it is funded as one of the six pilot projects currently funded as part of the Census of Marine Life (COML). It will be a 10-year-long undertaking over a vast part of the worlds oceans, funded by the Office of Naval Research in partnership with the Sloan and Packard Foundations.
In recent years, technology that allows us to examine the migrations of large oceanic animals (pop-up satellite archival tags, satellite-linked data recorders, archival and sonic tags) has proven enormously successful. Animal movements and behaviors can be linked to oceanographic processes by integrating biological and physical data providing both atmospheric and oceanographic information, and offering unprecedented insights into the relationship between physical ocean processes and top predators like tunas, dolphins, and sharks. Fifteen to twenty species of pelagic organisms from several trophic levels, many with similar patterns of spatial and temporal distributions, will be monitored throughout the North Pacific. Simultaneous tagging of the target marine species will permit the monitoring of their movement and behavior relative to environmental conditions. Results from TOPP will provide a framework for future management and conservation of these economically and ecologically valuable resources.
"To be able to electronically tag and track many individuals of several different species across immense areas of the ocean is a daunting task," says ONR marine mammal expert Robert Gisiner. "But, this program is going to allow us to study the movements of these animals both spatially and temporally at resolutions previously unknown."

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
