Bioacoustics: Cetaceans and Seeing Sounds
From: Woods Hole Oceanographic Institution
How does one see a sound? Scientists like Patrick Miller use a spectrogram, or visual representation
of sound waves graphed over time. Miller has created an engaging interactive series of actual recordings
and spectrograms of various marine mammals. Knowing how dolphins and whales communicate using sounds will
help us understand the effects of human-made noise on marine animals and find ways to create
more environmentally friendly devices, such as fishing nets that dolphins and whales can detect
and therefore avoid.

Marine Protected Areas: Finding a Balance Between Conservation and Fisheries Management
From: Woods Hole Oceanographic Institution
Compared to land-based national parks, only a tiny fraction of marine areas have been set aside
for protection and designated as marine protected areas (MPAs)--and many of these have varying
levels of restrictions on use. This seminar explains what MPAs are and discusses many of the most
important issues surrounding them in terms of their creation, design, monitoring and effects. Of
interest to not only people involved in conservation or fisheries groups, this seminar also
provides necessary background information for concerned citizens who participate in marine
activities or who want to know more about marine conservation and fisheries management issues.

Toxic Blooms: Understanding Red Tides
From: Woods Hole Oceanographic Institution
In recent years there has been a marked increase in what are commonly called "red tides."
Although not always red or even visible to the naked eye, each year these toxic algal blooms
make thousands sick and even cause death. This seminar explains the basic biology and ecology
of "red tides," including the organisms responsible, what kinds of toxins they produce,
and what possible measures can be taken to control them.
