Marine Mammal Die-Off Along Pacific Coast of North
America
BlueVoice.org,
a non-profit streaming video web site, has released
a report on the die-off of three species of marine mammals
along the west coast of North America. The report is
presented as a six minute film accompanied by synchronized
metadata as well as text.
Summary:
In recent years so-called "unusual mortality events"
have occurred with alarming frequency on the shore of
the eastern Pacific. Sea lions have died by the hundreds
from domoic acid poisoning, a result of harmful algal
blooms. Gray whales have died in unusual numbers during
the past two migration periods. The number of killer
whales in several well known pods have declined by 20
percent and more. Sea otters are dieing from diseases
resulting from pathogens to which they do not normally
sucumb.
Many reasons are cited for these die-offs but they are
probably the result of synergies of overfishing, warming
ocean temperatures, and the many forms of pollution
of the marine ecosystem.
"Providing packages of information in the annotated
streaming video format is a new way of getting both
video and text information to the public, journalists
and legislators with high impact," says Hardy Jones,
executive director of BlueVoice.org.
As the video streams it is paralleled by synchronized
data, which may include text, web hyperlinks, spread
sheets and graphics. BlueVoice.org can, in many cases,
provide video to support broadcast journalists in producing
stories on subjects we cover.
