Introduction
My current research pursuits involved integration of passive acoustic analysis techniques with spatial analysis of marine ecological data in order to better understand marine mammal habitat use. I utilize various analytical software and accessible data for ocean science research purposes, and develop online technical training courses related to my expertise.

Article
Culture, a pillar of the remarkable ecological success of humans, is increasingly recognized as a powerful force structuring nonhuman animal populations. A key gap between these two types of culture is quantitative evidence of symbolic markers—seemingly arbitrary traits that function as reliable indicators of cultural group membership to conspecifi...

As an Arctic gateway, the Norwegian Sea sustains a rich diversity of seasonal and resident species of soniferous animals, vulnerable to the effects of climate change and anthropogenic activities. We show the occurrence of seasonal patterns of acoustic signals in a small canyon off Northern Norway, and investigate cetacean vocal behavior, human-made...
Article
As the collection of large acoustic datasets used to monitor marine mammals increases, so too does the need for expedited and reliable detection of accurately classified bioacoustic signals. Deep learning methods of detection and classification are increasingly proposed as a means of addressing this processing need. These image recognition and clas...

This presentation demonstrates how to create a deep neural network in Ketos and import to PAMGuard for use in detection of marine mammal calls within a GUI framework.
Poster
Habitat characterization of marine mammal species using remotely sensed and in situ data from the Ocean Observatories Initiative cabled arrays. We combined acoustic derived marine mammal observations with information from the OOI sensors and remotely sensed chlorophyll data to describe ecosystem characteristics and explore indirect measures of prey...
Article
No PDF available ABSTRACT Southern Resident killer whales (SRKW) were listed as endangered in 2005, requiring designation of Critical Habitat. At that time little was known about SRKW distribution in winter/spring along the outer coast. From 2004 to 2016, we conducted nine winter/spring surveys aboard NOAA ocean-class vessels to locate and follow S...
Article
No PDF available ABSTRACT The Pacific Region International Survey of Marine Megafauna was conducted in the summer of 2018 to determine the distribution and abundance of cetaceans within the coastal and offshore waters of Canada. Tom Norris led the passive acoustic monitoring operations for this survey, and his Bio-Waves team of bioacousticians cond...
Article
Full-text available
Impulsive sounds generated during seismic surveys have elicited behavioral responses in marine mammals and could cause hearing impairment or injury. Mitigating exposure to seismic sound often relies on real-time marine mammal detection. Detection performance is influenced by detection method, environmental conditions, and observer experience. We co...

The coastal waters off Newport, Oregon are part of a naturally dynamic ecosystem influenced by the California Current. In additional to highly variable inter-annual and decadal processes, recent environmental monitoring has indicated instances of persistent warm water masses in the region. One method of assessing long standing shifts in the ecology...
Presentation
The National Science Foundation-funded Ocean Observatories Initiative (OOI) maintains a series of coastal and oceanic monitoring sites that consists of a multitude of physical and biological sensors. As part of this program, OOI has collected continuous, broadband passive acoustic data along the continental shelf and slope off Newport, Oregon since...

The minke whale is one of the most abundant species of baleen whales worldwide, yet is rarely sighted in subtropical waters. In the North Pacific, they produce a distinctive sound known as the “boing,” which can be used to acoustically localize individuals. A vessel-based survey using both visual and passive acoustic monitoring was conducted during...

Passive acoustic data collected from marine autonomous recording units deployed off Jacksonville, FL (from 13 September to 8 October 2009 and 3 December 2009 to 8 January 2010), were analyzed for detection of cetaceans and Navy sonar. Cetaceans detected included Balaenoptera acutorostrata, Eubalaena glacialis, B. borealis, Physeter macrocephalus, b...
Presentation
A visual and acoustic line-transect survey of marine mammals was conducted in the central Gulf of Alaska (GoA) during the summer of 2013. The survey area was divided into four sub-strata to reflect four distinct habitats; “inshore,” “slope,” “offshore,” and “seamount.” Passive acoustic monitoring was conducted using a towed-hydrophone array system....
Presentation
Sperm whales are social cetaceans that live in matrilineal family units, and inhabit all major ocean basins from the tropics to polar regions. They produce stereotyped patterns of 3 to 40 broadband clicks, termed ”codas,” that typically occur within a period of less than 3 s. Coda repertoires can be assigned to a ”vocal clan,” a type of social grou...
Presentation
Passive acoustic data were collected from nine Marine Autonomous Recording Units (MARUs) deployed 60-150 km in an area that coincides with the U.S. Navy’s planned Undersea Warfare Training Range (USWTR) off Jacksonville FL. MARUs were deployed for 26 days during fall 2009, and 37 days in winter 2009-2010. Data were manually reviewed for marine mamm...

Nine Marine Autonomous Recording Units (MARU’s) were deployed in a rectangular array at a site coinciding with the United States (U.S.) Navy’s planned Undersea Warfare Training Range (USWTR) approximately 60-150 km offshore Jacksonville, FL (13 September to 8 October and 3 December to 8 January, 2009-2010) at shallow, mid-depth, and deep sites (45,...
