Scientists wiring oceans to protect ecosystems

Washington: Scientists
are wiring oceans to track the movements of deep sea creatures
that could help protect marine ecosystems by revolutionizing how
we understand their function, population structure, fisheries
management and species' physiological and evolutionary
constraints.
Barbara Block, marine sciences professor at the Stanford
University's Woods Institute, is using technology to enable live
feeds of animal movements relayed by a series of "ocean WiFi
hotspots".
Block is studying pelagic (deep sea) creatures with telemetry
tags. The miniaturisation of sensors for tags, combined with
acoustic receiver-carrying mobile glider platforms and
instrumented buoys, has vastly expanded researchers' capacity to
obtain data from ocean organisms as tiny as bacteria and as large
as blue whales, according to a Stanford statement.
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 programme, 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.
These findings were presented at the 2013 American Association for
the Advancement of Science symposium in Boston.
