The Dataset's Variables and Attributes

Row Type	Variable Name	Attribute Name	Data Type	Value
attribute	NC_GLOBAL	abstract	String	This record represents killer whale sound production. Killer whale calls were detected by analysts and logged using Triton's Logger Remora. Calls were grouped into encounters, with encounters more than 30 min apart being logged as separate encounters. The following settings were used for manual scanning of long-term spectral averages: bandwidth 0-5000 Hz; 1 hour duration; and for zoomed-in scanning of spectrograms: plot length 30 s, FFT length 1000, 90% overlap. Killer whale encounters were further classified into ecotypes based on the presence of ecotype-specific call types in the encounter. Call types were identified in the spectrogram window, and all calls in an encounter were examined before an encounter was attributed to a particular ecotype. Resident ecotype call types were identified from the reference catalogue of Ford 1987, transient ecotype call types were identified from a reference catalogue based on recordings published by Deecke 2003, and offshore ecotype call types were identified from a digital catalogue (J Ford, unpubl. data) collected during field encounters with photo- or genetically identified offshore killer whales.These data were recorded at SanctSound Site OC02_05 between June 09, 2021 and October 27, 2021.

attribute	NC_GLOBAL	summary	String	NOAA and the U.S. Navy are working to better understand underwater sound within the U.S. National Marine Sanctuary System. 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.
