ADRIFT In the California Current 2021-2024 Raw Audio

ADRIFT in the California Current uses passive acoustic drifting buoys to study ocean sound in the California Current Ecosystem.  These autonomous buoys drift with currents and are tracked via satellite messenger. Data collected through the ADRIFT project will be used to assess noise levels and seasonal marine mammal acoustic presence in the California Current.

DCLDE 2026: Killer whale (Orcinus orca) ecotype and other species annotations for the Detection Classification Localization and Density Estimate (DCLDE) conference in 2026

Killer whales (Orcinus orca) exhibit significant ecological and genetic diversity, with three primary sympatric ecotypes in the Northeast Pacific: Resident, Biggâs (Transient), and Offshore. Each ecotype is adapted to distinct ecological niches, with unique foraging strategies, social structures, and vocal behaviors. These differences underscore the challenges in monitoring and conserving each group, as they coexist within overlapping geographic ranges yet do not intermix. This dataset, compiled from diverse sources, provides a comprehensive resource for the detection and classification of killer whale vocalizations. The >225,000 call-level annotations collected from 23 locations, and a cleaned annotation csv that collates annotations across the different protocols. Recordings spanning eleven years from various geographical locations within the Northeast Pacific Ocean, collected using multiple hydrophone systems. It addresses the challenge of differentiating killer whale calls from other marine species and environmental noise and includes specific instances of confounding signals to enhance model robustness. Detailed annotations capture a broad spectrum of vocalizations and associated metadata, facilitating the development of advanced machine learning models for ecological monitoring. This curated dataset aims to improve the accuracy of killer whale detection algorithms, support conservation efforts, and advance our understanding of killer whale acoustic communication across different ecotypes.

EK80 Water Column Sonar Data Collected During PC2403_Leg1

This project will provide critical data to NOAA and to the Mesophotic and Deep Benthic Communities (MDBC) projects. These data will be used for restoration and to guide future science-based management decisions. Without this project, NOAA and partners will not be able to use the best available science to guide their actions, including protection and restoration actions for sensitive communities.  

This expedition is part of the DWH Open Ocean TIG Final Restoration Plan 2 for MDBC. This plan will have direct consequences for defining the distribution, connectivity, and ecology of vulnerable ecological communities and guiding wise use of the living marine and energy resources

ME70 Water Column Sonar Data Collected During RL1503

Multi-frequency (18-, 38-, 70-, 120-, and 200-kHz) General Purpose Transceivers (Simrad EK60 GPTs), were configured with split-beam transducers (Simrad ES18-11, ES38B, ES70-7C, ES120-7C, and ES200-7C, respectively). The transducers were mounted on the bottom of a retractable keel or âcenterboardâ. The keel was retracted (~ 5-m depth) during calibration, and extended to the intermediate position (~7-m depth) during the survey. Exceptions were made during shallow water operations, when the keel was retracted to ~ 5-m depth; or during times of heavy weather, when the keel was extended to ~9-m depth to provide extra stability and reduce the eËect of weather-generated noise. Data was also collected using a ME70.

EK80 Water Column Sonar Data Collected During PC2201_Leg4

NOAA Ship Pisces conducted a survey of reef fish located on the U.S. continental shelf and shelf-edge of the Gulf of Mexico from April 19 through June 22, 2022. Eighty blocks containing 536 sites were selected to be sampled with Spherical/Satellite array, bandit reels, and CTD during daylight hours. Individual sampling sites were supplied prior to sailing. Mapping was conducted at night at randomly selected areas near the following or previous day's sampling.

EK80 Water Column Sonar Data Collected During DY2207

The Midwater Assessment and Conservation Engineering (MACE) program of NOAA Fisheries, Alaska Fisheries Science Center (AFSC), conducted an acoustic-trawl (AT) stock assessment survey on the Easter Bering Sea shelf from Bristol Bay to U.S.-Russia Convention Line in the late spring and summer of 2022 to estimate the distribution and abundance of walleye pollock (Gadus chalcogrammus). This survey was conducted aboard NOAA Ship Oscar Dyson (built in 2003, 64 meters, 2500 tons, 3100 hp), a research stern trawler equipped with acoustic and oceanographic instrumentation. The primary water column acoustic instrument for the survey was a Kongsberg EK80 split-beam scientific echosounder system utilizing five frequencies (18, 38, 70, 120, and 200 kHz). Trawl operations were conducted using an LFS1421 mid-water trawl net. 

The survey was conducted in three legs starting and ending in Dutch Harbor, Alaska with intermediate port calls in Dutch Harbor. Survey leg 1 was conducted 3-15 June, leg 2 was 22 June to 8 July, and leg 3 was 20 July to 5 August; the dates listed are for actual survey operations and do not include the additional transit time between port and area of operations. The delay between legs 2 and 3 was due to vessel staffing issues. Calibrations of the EK80 echosounder system were conducted prior to starting the survey (31 May), at the end of leg 2 (9 July), and at the end of the survey (5 August) in Captains Bay, Unalaska Island (Dutch Harbor), Alaska.

MS70 Water Column Sonar Data Collected During RL1703

During spring 2017, part of the west coast of the United States was surveyed using Lasker during the principal spawning seasons of sardine and anchovy. Since the central sub-population of anchovy inhabits southern and central California during the spring, the survey began off San Diego and progressed northward toward San Francisco. Transect positions, lengths, and spaces were adjusted according to the expected distribution of anchovy at the time of the survey. Compulsory transects were nearly perpendicular to the coast with nominal separations of 20 nmi; adaptive transects were placed between compulsory transects to reduce nominal separation to 10 nmi when the survey encountered putative CPS backscatter in echograms, high-density eggs in the CUFES (1 or 0.3 eggs min-1 for anchovy or sardine, respectively), or adults in trawls. After initiating adaptive acoustic sampling, the adaptive transect immediately south of the completed compulsory transect was sampled before proceeding northward along the next adaptive and compulsory transects. An adaptive cluster was defined as a minimum of five consecutive transects with 10-nmi spacing. The transect positions also covered much of the potential habitat of sardine at the time of the survey. The survey spanned an area from approximately San Diego to San Francisco, with 27 east-west transects totaling 1828 nmi, and 64 Nordic trawls.

Multi-frequency (18, 38, 70, 120, 200, and 333 kHz) General Purpose Transceivers (Simrad EK60 GPTs) and Wideband Transceivers (Simrad EK80 WBTs) were configured with split-beam transducers (Simrad ES18-11, ES38B, ES70-7C, ES120-7C, ES200-7C, and ES333-7C, respectively). The transducers were mounted on the bottom of a retractable keel or âcenterboardâ. The keel was retracted (~ 5-m depth) during calibration, and extended to the intermediate position (~7-m depth) during the survey. Exceptions were made during shallow water operations, when the keel was retracted to ~ 5-m depth; or during times of heavy weather, when the keel was extended to ~9-m depth to provide extra stability and reduce the effect of weather-generated noise. In addition, acoustic data were also collected using an ME70 multibeam echosounder (Simrad) and MS70 multibeam sonar (Simrad).
