Abstract

Underwater sound levels near Block Island were monitored during wind turbine construction and operational phases to detect acoustic signals and sediment-borne vibrations, with the objective of collecting real-time data to improve model predictions for future offshore wind facilities. Two monitoring phases were conducted: 1. Construction Phase Monitoring (July-October 2015) Acoustic monitoring during pile driving operations using: - Stationary Arrays: Fixed hydrophone stations near foundations (750 m), including SHRU (Several Hydrophone Receiving Unit) moorings with four-hydrophone vertical line arrays - Mobile Arrays: Sensor-equipped geosleds with tetrahedral hydrophone arrays and geophone packages, plus mobile towed arrays deployed at varying depths and locations - Drifting Hydrophones: Multi-depth acoustic recordings with seabed vibration monitoring to capture sound propagation variability 2. Operational Phase Monitoring (October-November 2017) Long-term acoustic monitoring during wind turbine operations using: - SHRU vertical line array moorings at multiple distances from operational turbines - Geophone sled with tetrahedral array for seabed acoustic and particle motion measurements - Horizontal line array (HLA) for spatial acoustic characterization This dataset includes: Spectrograms: Frequency-over-time visualizations of acoustic intensity from construction pile driving and operational turbine noise Audio Recordings: Raw underwater acoustic data segmented by channels from multi-hydrophone arrays Signal Time Metadata: Timestamps for logged acoustic eventsmore »« less

Block Island Noise Modeling Data

Dataset Khan, Anwar ; Bigger, David

Noise propagation near Block Island was simulated to assess environmental impacts of impact pile driving during wind turbine construction. Computational models complement field-recorded acoustic data, providing insights into sound attenuation, spectral variability, and propagation dynamics. The dataset includes: 1. Propagation Models: Simulated underwater sound fields documenting sound pressure and directional variability across frequency bands and distances. 2. Spectral Analysis (LTSA): Long-term averages and processed outputs calculating acoustic intensity over time. 3. Visualization Files: Graphs, 2D/3D simulation results, and reference calculations used in sound modeling.
NOAA PSL Microwave Radiometer Block Island / Thermodynamic retrievals TROPoe

Dataset Adler, Bianca

This dataset contains daily files with thermodynamic profiles retrieved with the optimal estimation physical retrieval TROPoe (Turner and Löhnert 2014; Turner and Blumberg 2019; Turner and Löhnert 2021). The profiles are retrieved every 10 minutes from instantaneous brightness temperature measurements at 35 channels observed with a microwave radiometer MP3000A operated by NOAA Physical Sciences Laboratory on the Block Island for WFIP3. Additional input data in TROPoe are cloud base height from a collocated ceilometer operated by NOAA GML and temperature, water vapor mixing ratio, and pressure from a sensor attached to the MWR housing.

Nauru Island Effect Detection Data Set

Dataset Long, Chuck

During Nauru99 it was noted that the island was producing small clouds that advected over the ARM site. The Nauru Island Effect Study was run for 1.5 years and the methodology developed to detect the occurrence. Nauru ACRF downwelling SW, wind direction, and air temperature data are used, along with downwelling SW data from Licor radiometers located on the southern end of the island near the airport landing strip. A statistical analysis and comparison of data from the two locations is used to detect the likely occurrence of an island influence on the Nauru ACRF site data
