Wiring the ocean

18.02.2013
For most people, the sea is a deep, dark mystery. That is changing, though, as scientists find innovative ways to track the movements of ocean-going creatures.

Stanford marine sciences professor and Stanford Woods Institute Senior Fellow Barbara Block is using technology to enable live feeds of animal movements relayed by a series of "ocean WiFi hotspots." This could help protect marine ecosystems by revolutionizing how we understand their function, population structure, fisheries management and species' physiological and evolutionary constraints.

Block will explain how she is studying pelagic creatures with telemetry tags, and how she plane to "wire" the ocean at the annual American Association for the Advancement of Science (AAAS) meeting in Boston. Her talk, "Building a Wired Ocean With Electronic Tagged Animals and Mobile Gliders," will be part of a symposium called "Networks of Discovery: Delivering Unsurpassed Insight Into Changing Global Ecosystems" from 1:30 to 4:30 p.m. on Feb. 17 in room 312 of the Hynes Convention Center.

The miniaturization of sensors for tags, combined with acoustic receiver-carrying mobile glider platforms and instrumented buoys, has vastly expanded our capacity to obtain data from oceans at levels as small as bacteria and as large as blue whales. Block's work is part of a larger effort to establish a global network of instruments to more comprehensively study the biosphere as it is altered – at unprecedented rates – by human activity and climate change.

Block's project, the Blue Serengeti Initiative, builds on the Tagging of Pacific Predators program, part of the global Census of Marine Life, a decade-long study that invested $25 million in electronic tagging, enabling marine scientists from five nations to map ocean hot spots within the California Current.

At the AAAS meeting in Boston, Block will discuss her new project and explain how she uses wireless devices track the comings and goings of key ocean species.

Block is the Charles and Elizabeth Prothro Professor in Marine Sciences at Stanford University. Her lab is based at Stanford's Hopkins Marine Station, and her research focuses on how large pelagic fishes utilize the open ocean environment. Block and colleagues at the Monterey Bay Aquarium established the Tuna Research and Conservation Center, where they are employing new techniques in remote wildlife tracking and data collection, and molecular genetics to directly examine the short- and long-term movement patterns, population structure and behavior of tunas and billfishes.

Im Focus: Mapping electromagnetic waveforms

Munich Physicists have developed a novel electron microscope that can visualize electromagnetic fields oscillating at frequencies of billions of cycles per second.

Temporally varying electromagnetic fields are the driving force behind the whole of electronics. Their polarities can change at mind-bogglingly fast rates, and...

Im Focus: Continental tug-of-war - until the rope snaps

Breakup of continents with two speed: Continents initially stretch very slowly along the future splitting zone, but then move apart very quickly before the onset of rupture. The final speed can be up to 20 times faster than in the first, slow extension phase.phases

Present-day continents were shaped hundreds of millions of years ago as the supercontinent Pangaea broke apart. Derived from Pangaea’s main fragments Gondwana...

Scaffolding and specialised workers help with the delivery – Heidelberg biochemists gain new insights into biogenesis

A type of scaffolding on which specialised workers ply their trade helps in the manufacturing process of the two subunits from which the ribosome – the protein...

Im Focus: New protocol enables analysis of metabolic products from fixed tissues

Scientists at the Helmholtz Zentrum München have developed a new mass spectrometry imaging method which, for the first time, makes it possible to analyze hundreds of metabolites in fixed tissue samples. Their findings, published in the journal Nature Protocols, explain the new access to metabolic information, which will offer previously unexploited potential for tissue-based research and molecular diagnostics.

In biomedical research, working with tissue samples is indispensable because it permits insights into the biological reality of patients, for example, in...

Im Focus: Computer Simulation Renders Transient Chemical Structures Visible

Chemists at the University of Basel have succeeded in using computer simulations to elucidate transient structures in proteins. In the journal Angewandte Chemie, the researchers set out how computer simulations of details at the atomic level can be used to understand proteins’ modes of action.

Using computational chemistry, it is possible to characterize the motion of individual atoms of a molecule. Today, the latest simulation techniques allow...
