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."

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
