Researchers are enlisting seals, sea lions, tunas, and sharks to serve as ocean sensors, outfitting these top predators with electronic tags that gather detailed reports on oceanographic conditions and, in many cases, transmit the data via satellite. The data are proving useful to both biologists and oceanographers, yielding new information about the migrations and behavior of the animals and about the environments in which they live.
"Were using these animals as ocean sensors to tell us about oceanographic conditions, and were also learning how they use the ocean--where they go and what they do," said Daniel Costa, professor of ecology and evolutionary biology at the University of California, Santa Cruz.
Costa, along with Barbara Block of Stanford University, is a principal investigator on a Census of Marine Life project called Tagging Of Pacific Pelagics (TOPP), which is deploying electronic tags on 23 species of apex predators in the North Pacific Ocean. He is also collaborating with researchers at the Sea Mammal Research Unit (SMRU) at the University of St. Andrews in Scotland on a project in the Southern Ocean around Antarctica called Southern Elephant Seals as Oceanographic Samplers (SEaOS).

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
Two researchers at Heidelberg University have developed a model system that enables a better understanding of the processes in a quantum-physical experiment...
Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
