We will have a brief discussion about bats,
demonstrate acoustic monitoring, setup mist nets, and take a close up look at the bats as they are safely caught and released!
During the Acoustical Society of America's Fall 2015 Meeting, being held Nov. 2 - 6, in Jacksonville, Fla., Kathleen Stafford, principal oceanographer for the Applied Physics Lab at the University of Washington, will describe their work and the
passive acoustic monitoring techniques involved.
Despite substantial efforts by the Mexican government to protect vaquitas, the recovery team recently reviewed the latest results from advanced
acoustic monitoring technology that showed the vaquita population continuing to rapidly decline.
AndrewMF @ 47, the reported sea level rises by the Australian Baseline Sea Level Monitoring Project (ABSLMP) are measured by SEAFRAMEs (SEA - level Fine Resolution
Acoustic Monitoring Systems), as illustrated below:
Just last month, two of the six - foot, torpedo shaped gliders used their digital
acoustic monitoring equipment to detect nine North Atlantic right whales in the Gulf of Maine.
«This type
of acoustic monitoring could be helpful in locations that are difficult for divers to survey visually, such as deeper depths or murky waters,» he says.
With whales, WCS employs a range of techniques,
including acoustic monitoring, satellite tracking, and conservation genetics to better understand populations, to define their most biologically important habitats.

Advanced Acoustic Monitoring for Improved Control of Blood - Brain Barrier Opening with Focused Ultrasound Catherine M. Gorick, Natasha D. Sheybani, Colleen T. Curley, Richard J. Price Theranostics 2018; 8 (11): 2988 - 2991.
«This passive
acoustic monitoring technique allows us to detect the presence of vocalizing marine mammals continuously — 24 hours per day — in all weather conditions, over periods of weeks to months, over distances of 20 to 30 kilometers, and is a proven sampling method in the waters offshore Alaska,» explained Stafford.
World Wildlife Fund is contributing
with acoustic monitoring and the retrieval of lost or abandoned «ghost» nets from vaquita habitat.
Instruments are now so precise that radar observations can spot a single bee at about 30 miles away, and scientists can combine thermal imaging cameras,
acoustic monitoring devices and small portable radars with weather radar data to get a complete picture of a region's ecology.
«
Acoustic monitoring provides holistic picture of biodiversity: Soundscapes are allowing researchers to understand the spread and diversity of birds on Japanese island.»
«Our results highlight the potential use of
remote acoustic monitoring practices that, in combination with other methods, can provide a holistic picture of biodiversity,» says Ross.
The use of gliders and floats in passive
acoustic monitoring helps address the spatial and temporal tradeoff of stationary and towed instruments.
Many of these mammals produce specific vocalizations that can be used to identify the species and track their locations
via acoustic monitoring.
Scripps Institution of Oceanography researcher Dr. John Hildebrand talked about
how acoustic monitoring can be used to study marine mammals and shipping noise around the Channel Islands at the March «From Shore to Sea» lecture.
SA Instrumentation Limited are pioneers in real - time autonomous acoustic detection using
Passive Acoustic Monitoring (PAM) process, which is key for marine mammal monitoring and ideal for OEM integration like the Liquid Robotics, Wave Glider, and has been used to detect Beluga whales in Alaska and recently Dolphins off the East Coast of Carolina.
They included
an acoustic monitoring technology to improve coffee roasting, a handheld laser device to shape bones and -LSB-...]
The team's
acoustic monitoring was «extremely significant» while the wellhead was being closed, says Kathryn Moran, an oceanographer at the University of Rhode Island, Kingston.
In
this acoustic monitoring study, five pilot recording sites were set up in three city parks, a forest and a forested suburb on Okinawa, which is the largest and most inhabited island in the Ryūkyū archipelago.
Both
the acoustic monitoring and the net retrieval are conducted with the help and experience of local fishermen.
During the first three days, scientists spotted several vaquitas using visual search methods and
acoustic monitoring.
A crucial part of CPR is
the acoustic monitoring system that will help to locate the remaining vaquitas.
«Eavesdropping on Bering Strait marine mammals: Researchers are eavesdropping on marine mammals within the Bering Strait via «passive
acoustic monitoring» to observe changes in the ecology of the Pacific Arctic by documenting the use of this region by species previously excluded by sea ice.»
She worked as a research fellow for the Blue whale study and the Centre for Whale Research (Australia) conducting ecological modelling, passive
acoustic monitoring and habitat assessment for top predators (i.e. mainly marine mammals), and investigating biological responses to changes in habitat caused by natural and anthropogenic environmental variability.
To avoid local extirpation of these marine mammals (which are listed nationally as a «Matter of National Environmental Significance»), an experimental approach was used to evaluate two management approaches to mitigate bycatch: pingers (acoustic alarms) and passive
acoustic monitoring.
Passive
acoustic monitoring the distribution pattern of humpback dolphin and finless porpoise and underwater construction noise assessment are also my interested topics.
This has many applications including early tsunami warning, but also offers a cheap alternative to
acoustic monitoring with a moored hydrophone array which requires a ship to retrieve the data.
In addition to
the acoustic monitoring equipment, the gliders are also outfitted with environmental sensors that collect data about things like temperature and salinity, and the estimated algae population levels, which are at the base of the marine food chain.
