Current scientific data on affected biological and environmental resources are necessary to conduct analyses required for Navy training, exercise, and technology-acquisition activities. In the summer of 2013, the Navy funded a vessel-based survey (Gulf of Alaska Line-Transit Survey (GOALS)) to fill in the gaps of knowledge on distribution, movements, and densities of marine mammals within this training area. The Marine Mammal Laboratory conducted passive acoustic monitoring during this survey cruise. Directional Frequency Analysis and Recording (DiFAR) sonobuoys were deployed approximately every 2 to 3 hours to obtain an evenly sampled census of marine mammal vocalizations; a total of 186 sonobuoys were deployed. Sonobuoys were analyzed in real time for presence/absence of calls from cetaceans; calls were detected on 80 percent of the sonobuoys, including the study area and transit to Kodiak, Alaska. There were seven confirmed species detected: blue, fin, humpback, killer, sei, North Pacific right, and sperm whales, and additional call detections that could not be classified to species. All sonobuoys were provided by the United States Navy (Naval Operational Logistics Support Center, Naval Surface Warfare Center, Crane Division, and the Office of the Assistant Secretary of the Navy). The purpose of these sonobuoy deployments is to assess short-term presence, distribution, and relative abundance of marine mammals in the Gulf of Alaska, and also to locate vocalizing species of interest for photo-identification, tagging, and behavioral studies. The study was funded by the U.S. Navy and conducted through a collaboration between HDR Inc., Cascadia Research Collective, BioWaves Incorporated, and NOAA Fisheries. complete NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information pointOfContact Carrie Wall NOAA National Centers for Environmental Information NCEI Passive Acoustic Archive Lead pad.info@noaa.gov pointOfContact asNeeded https://www.ngdc.noaa.gov/mgg/pad/browse/AFSC_GA13.png Study area.

Data quality was assessed through visual analysis and examination of acoustic levels over time across all frequencies. Raw unprocessed passive acoustic data files. Sonobuoys have an analyst monitoring them in real time, typically. The recordings will have varying degrees of quality. The data can start out excellent, and then something can catastrophically happen with the signal and the recording will become unusable. Typically the analyst will stop the recording right after that happens. Normally, the signal will become weaker and weaker as the monitoring platfrom (vessel in this case) moves further away from the sonobuoy. Sometimes, the vessel will switch course and transit closer to the sonobuoy, in which case the signal will improve. Finally, sometimes the recordings are made with no analyst monitoring them in real time, but rather review the recordings later. In this case, there could be a lot of unusable recordings of static. All acousticians on a cruise will serve as quality analysts. asNeeded Based on the NCEI Collection Level Metadata Template v1.1 (https://data.noaa.gov/waf/templates/iso_u/xml/ncei_template-clean.xml).
