The Low Frequency Detection and Classification System (LFDCS) call library for fin whale 20-Hz pulses was built for the data sampled at 120 Hz. All fin whale detections with a Mahalanobis distance of 3.0 or less were manually verified for true detections. A logistic regression was applied to these results to facilitate reducing the size of the dataset that ultimately needed to be manually verified for confident species detection. This analysis revealed that a minimum number of 29 detections per time window used (hour or day) need to be detected to ensure that a fin whale was truly detected with a confidence of 90%. All days with at least 29 detections were manually verified for daily presence of fin whale 20-Hz pulses. From days with 29 or more detections, fin whales were considered present for that day if a true detection was found within a regular inter-pulse interval pattern of at least three other 20-Hz pulses.

From 2018 to 2021, these agencies will work with numerous scientific partners to study sound within seven national marine sanctuaries and one marine national monument, which includes waters off Hawai'i and the east and west coasts. Standardized measurements will assess sounds produced by marine animals, physical processes (e.g., wind and waves), and human activities. Collectively, this information will help NOAA and the Navy measure sound levels and baseline acoustic conditions in sanctuaries. This work is a continuation of ongoing Navy and NOAA research, including efforts by NOAA's Office of National Marine Sanctuaries This dataset represents the derived products from the raw acoustic data that are archived at NOAA National Centers for Environmental Information.\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n largerWorkCitation\r\n \r\n \r\n project\r\n \r\n \r\n \r\n \r\n eng; USA\r\n \r\n \r\n biota\r\n \r\n \r\n oceans\r\n \r\n \r\n \r\n \r\n Site SB01_03\r\n \r\n \r\n \r\n \r\n -70.5467833\r\n \r\n \r\n -70.5467833\r\n \r\n \r\n 42.4371\r\n \r\n \r\n 42.4371\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n 2019-04-10T04:00:00Z\r\n 2019-06-01T15:00:00Z\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Passive acoustic data\r\n \r\n \r\n physicalMeasurement\r\n \r\n \r\n \r\n \r\n \r\n \r\n timestamp\r\n \r\n \r\n \r\n \r\n string\r\n \r\n \r\n \r\n \r\n \r\n \r\n Timestamp in ISO 8601 date format\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n presence\r\n \r\n \r\n \r\n \r\n double\r\n \r\n \r\n \r\n \r\n \r\n \r\n Presence of Fin Whale (0 = not present; 1 = present)\r\n \r\n \r\n 1\r\n \r\n \r\n 0\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n presence\r\n \r\n \r\n \r\n \r\n double\r\n \r\n \r\n \r\n \r\n \r\n \r\n The Low Frequency Detection and Classification System (LFDCS) call library for fin whale 20-Hz pulses was built for the data sampled at 120 Hz.

Data quality was assessed through visual analysis and examination of acoustic levels over time across all frequencies.\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n All acoustic data were processed using the Low Frequency Detection and Classification System (LFDCS; Baumgartner and Mussoline, 2011), which creates conditioned spectrograms using a short-time Fourier transform with a data frame of 512 samples and 75% overlap (80% overlap for the 120 Hz decimated data (blue and fin whales)), resulting in a time step of 64 ms and frequency resolution of 3.9 Hz (for 120 Hz data: 853 ms time step and 0.23 Hz frequency resolution). After tracing contour lines, or \u201cpitch tracks\u201d, through tonal sounds, the program uses multivariate discriminant function analysis to classify the pitch tracks into species-specific call types based on a call library. Each detection is assigned a Mahalanobis distance (MD), which measures the deviation of a sound\u2019s pitch track from the assigned call type (see Baumgartner and Mussoline (2011) for a more complete description). A lower MD indicates a closer match to the assigned call type. For a well-developed call type in the LFDCS (i.e., the seven attributes used in the discriminant function analysis are multivariate normal), 75% of pitch-tracks for the call type will have a MD of 3.0 or less (Baumgartner et al., 2013). Setting a MD threshold is necessary to minimize the false detection rates, but in doing so causes some true detections to be missed in the analysis. The MD threshold of 3.0 was chosen for all vocalizations detected and classified in the humpback, sei, and fin whale call library. However, for blue whales, false detection rates were lower than any of the other species, thus a MD of 5.0 was chosen to decrease the probability of missing true detections. All LFDCS detections were manually reviewed by trained acoustic analysts to determine daily presence of each of the four baleen whale species. A true detection was defined as a pitch track that correctly classified a call or song unit to the species that produced it (Bonnell et al., 2016). Given the variability of each species' call type, the specific methodology to determine daily acoustic presence was different for each species. The LFDCS call library for fin whale 20-Hz pulses was built for the data sampled at 120 Hz. All fin whale detections with a MD of 3.0 or less were manually verified for true detections. A logistic regression was applied to these results to facilitate reducing the size of the dataset that ultimately needed to be manually verified for confident species detection. This analysis revealed that a minimum number of 29 detections per time window used (hour or day) need to be detected to ensure that a fin whale was truly detected with a confidence of 90%. All days with at least 29 detections were manually verified for daily presence of fin whale 20-Hz pulses. From days with 29 or more detections, fin whales were considered present for that day if a true detection was found within a regular inter-pulse interval pattern of at least three other 20-Hz pulses.\r\n \r\n \r\n \r\n \r\n \r\n \r\n Data were processed with LFDCS\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n LFDCS\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n asNeeded\r\n \r\n \r\n Based on the NCEI Collection Level Metadata Template v1.1 (https://data.noaa.gov/waf/templates/iso_u/xml/ncei_template-clean.xml).\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Fixed Observation Stations\r\n \r\n \r\n \r\n \r\n Self-contained underwater sound recorder for long term ocean deployments.\r\n \r\n \r\n \r\n \r\n \r\n \r\n SoundTrap ST300\r\n \r\n \r\n \r\n \r\n long term recorder\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n","source_transform":{"@type":"dcat:Dataset","accessLevel":"non-public","contactPoint":{"@type":"vcard:Contact","fn":"NOAA National Centers for Environmental Information","hasEmail":"mailto:ncei.info@noaa.gov"},"describedByType":"application/octet-steam","description":"This record represents fin whale sound production detected from raw passive acoustic data.

From 2018 to 2021, these agencies will work with numerous scientific partners to study sound within seven national marine sanctuaries and one marine national monument, which includes waters off Hawai'i and the east and west coasts. Standardized measurements will assess sounds produced by marine animals, physical processes (e.g., wind and waves), and human activities. Collectively, this information will help NOAA and the Navy measure sound levels and baseline acoustic conditions in sanctuaries.
