Susan Parks is an ecologist at Syracuse University known for her research on acoustic signaling and the impact of ambient noise on communication in marine mammals.
Parks obtained a B.A. in Biology from Cornell University (1998) and a Ph.D. in Biological Oceanography from the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution (2003). [1] Following her time in Woods Hole, Parks was a postdoctoral investigator at Cornell University before joining the faculty at Pennsylvania State University. Parks is currently an associate professor of Biology at Syracuse University. [2]
At a young age, Parks' father introduced her to recordings of whale sounds and, in a 2010 interview, Parks describes the connection between this moment and an undergraduate animal behavior class that led her to a research project with frogs and ultimately her Ph.D. research on right whales. [3] During her Ph.D., Parks used an historical archive of whale sounds and determined that right whale calls increased in volume when ambient noise levels increased. [4] [5] Parks has also used tags temporarily placed on right whales to study their ecology [6] and research by Holly Root-Gutteridge, a postdoctoral investigator working with Parks, has revealed that right whale songs change over a whale's lifespan. [7] By tracking the 'gunshot' sound made by right whales, Parks and colleagues determined that right whales use Roseway Basin, a region of the Scotian Shelf, from August to November as an area for breeding. [8] [9]
Through the use of sound, Parks has also examined the connection between higher temperatures and sound in katydids, [10] traffic noise and frogs, [11] [12] and seals that may not be loud enough to overcome noise levels from human activities. [13] Parks, Jennifer Miksis-Olds, and Samuel Denes have used sound to define the bounds of biological habitats. [14] Whales vary the noises they make and Parks' research has described the soft sounds used by mother and calf pairs as 'whispers' which may avoid the unwanted attention of predators. [15] [16] The clock-like sounds in humpback whales could be a signal to nearby whales about the presence of food or a means to get the whales' prey to come out of the sand. [17] [18] After the 9/11 attacks, an unplanned collaboration between Parks, Rosalind Rolland, and a team of researchers [19] [20] concluded that a short-term reduction in ship noise altered hormone levels in whales. [21] [22]
In addition to her research, Parks mentors women in science and in 2016 Parks said she "...wanted to be a senior scientist in the field to provide young women an example of a female role model." [23]
Noise pollution, or sound pollution, is the propagation of noise or sound with ranging impacts on the activity of human or animal life, most of which are harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems. Poor urban planning may give rise to noise disintegration or pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas. Some of the main sources of noise in residential areas include loud music, transportation, lawn care maintenance, construction, electrical generators, wind turbines, explosions and people.
Baleen whales, also known as whalebone whales, are marine mammals of the parvorder Mysticeti in the infraorder Cetacea, which use keratinaceous baleen plates in their mouths to sieve planktonic creatures from the water. Mysticeti comprises the families Balaenidae, Balaenopteridae (rorquals), Eschrichtiidae and Cetotheriidae. There are currently 16 species of baleen whales. While cetaceans were historically thought to have descended from mesonychians, molecular evidence instead supports them as a clade of even-toed ungulates (Artiodactyla). Baleen whales split from toothed whales (Odontoceti) around 34 million years ago.
The humpback whale is a species of baleen whale. It is a rorqual and is the only species in the genus Megaptera. Adults range in length from 14–17 m (46–56 ft) and weigh up to 40 metric tons. The humpback has a distinctive body shape, with long pectoral fins and tubercles on its head. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song typically lasting 4 to 33 minutes.
Right whales are three species of large baleen whales of the genus Eubalaena: the North Atlantic right whale, the North Pacific right whale and the Southern right whale. They are classified in the family Balaenidae with the bowhead whale. Right whales have rotund bodies with arching rostrums, V-shaped blowholes and dark gray or black skin. The most distinguishing feature of a right whale is the rough patches of skin on its head, which appear white due to parasitism by whale lice. Right whales are typically 13–17 m (43–56 ft) long and weigh up to 100 short tons or more.
The southern right whale is a baleen whale, one of three species classified as right whales belonging to the genus Eubalaena. Southern right whales inhabit oceans south of the Equator, between the latitudes of 20° and 60° south. In 2009 the global population was estimated to be approximately 13,600.
Balaenidae is a family of whales of the parvorder Mysticeti that contains mostly fossil taxa and two living genera: the right whale, and the closely related bowhead whale.
The North Atlantic right whale is a baleen whale, one of three right whale species belonging to the genus Eubalaena, all of which were formerly classified as a single species. Because of their docile nature, their slow surface-skimming feeding behaviors, their tendencies to stay close to the coast, and their high blubber content, right whales were once a preferred target for whalers. At present, they are among the most endangered whales in the world, and they are protected under the U.S. Endangered Species Act and Marine Mammal Protection Act and Canada's Species at Risk Act. There are around 356 individuals in existence in the western North Atlantic Ocean—they migrate between feeding grounds in the Labrador Sea and their winter calving areas off Georgia and Florida, an ocean area with heavy shipping traffic. In the eastern North Atlantic, on the other hand—with a total population reaching into the low teens at most—scientists believe that they may already be functionally extinct. Vessel strikes and entanglement in fixed fishing gear, which together account for nearly half of all North Atlantic right whale mortality since 1970, are their two greatest threats to recovery.
The North Pacific right whale is a very large, thickset baleen whale species that is extremely rare and endangered. On average and maximum weight, they are the second largest whale species in the world.
Whales use a variety of sounds for communication and sensation. The mechanisms used to produce sound vary from one family of cetaceans to another. Marine mammals, including whales, dolphins, and porpoises, are much more dependent on sound than land mammals due to the limited effectiveness of other senses in water. Sight is less effective for marine mammals because of the way particulates in the ocean scatter light. Smell is also limited, as molecules diffuse more slowly in water than in air, which makes smelling less effective. However, the speed of sound is roughly four times greater in water than in the atmosphere at sea level. As sea mammals are so dependent on hearing to communicate and feed, environmentalists and cetologists are concerned that they are being harmed by the increased ambient noise in the world's oceans caused by ships, sonar and marine seismic surveys.
Zoomusicology is the study of the musical aspects of sound and communication as produced and perceived by animals. It is a field of musicology and zoology, and is a type of zoosemiotics. Zoomusicology as a field dates to François-Bernard Mâche's 1983 book Music, Myth, and Nature, or the Dolphins of Arion, and has been developed more recently by scholars such as Dario Martinelli, David Rothenberg, Hollis Taylor, David Teie, and Emily Doolittle.
Ocean acoustic tomography is a technique used to measure temperatures and currents over large regions of the ocean. On ocean basin scales, this technique is also known as acoustic thermometry. The technique relies on precisely measuring the time it takes sound signals to travel between two instruments, one an acoustic source and one a receiver, separated by ranges of 100–5,000 kilometres (54–2,700 nmi). If the locations of the instruments are known precisely, the measurement of time-of-flight can be used to infer the speed of sound, averaged over the acoustic path. Changes in the speed of sound are primarily caused by changes in the temperature of the ocean, hence the measurement of the travel times is equivalent to a measurement of temperature. A 1 °C (1.8 °F) change in temperature corresponds to about 4 metres per second (13 ft/s) change in sound speed. An oceanographic experiment employing tomography typically uses several source-receiver pairs in a moored array that measures an area of ocean.
Whale barnacles are species of acorn barnacle that belong to the family Coronulidae. They typically attach to baleen whales, and sometimes settle on toothed whales. The whale barnacles diverged from the turtle barnacles about three million years ago.
The interactions between marine mammals and sonar have been a subject of debate since the invention of the technology.
The Scotian Shelf is a geological formation, part of the Continental shelf, located southwest of Nova Scotia, Canada. It covers an area of 120,000 square kilometres (46,000 sq mi), is 700 kilometres (430 mi) long and ranges in width from 120 to 240 kilometres. It has an average depth of 90 metres (300 ft). The Scotian Shelf contains the ecologically important Scotian Shelf Large Marine Ecosystem (LME) and the Scotian Shelf Waters (SSW).
Coronula diadema is a species of whale barnacle that lives on the skin of humpback whales and certain other species of whale. This species was first described by Carl Linnaeus in the 1767 12th edition of his Systema Naturae.
