- Description
- The U.S. Department of Commerce, Atlantic Oceanographic and Meteorological Laboratory in Miami, FL is need of a situ instrumentation to measure ocean currents and waves for estimation of watermass residence times and mixing at the NOAA Atlantic Ocean Acidification Testbed (AOAT). Specifications/Statement: Statement of Work for purchase of equipment to estimate water residence times at Atlantic Ocean Acidification Testbed for NOAA/AOML: Item: In situ instrumentation to measure ocean currents and waves for estimation of watermass residence times and mixing at the NOAA Atlantic Ocean Acidification Testbed (AOAT) Category: Oceanographic scientific equipment Narrative: As part of the Coastal ocean acidification observing and warning system, AOML has been funded by the NOAA Coral Reef Conservation Program (CRCP) to set up a monitoring and research Testbed for measuring marine carbonate chemistry parameters on coral reefs. This includes procuring instruments to measure physical variables bearing on carbonate chemistry dynamics, among them wave spectra and ocean current profiles necessary to estimate wave mixing and watermass residence times near the Testbed. Ocean circulation varies significantly over kilometer scales in the region of the projected Testbed deployment (Haus et al. 2004), including vortices and other coherent circulation features (Shay et al. 2002), and significant current variability with water depth under some conditions (Shay et al. 1998). Therefore, it is necessary to obtain water-column profile measurements of ocean currents at multiple points in order to avoid significant underestimation of watermass residence times. We seek a commercial vendor to provide units to the exacting specifications listed below. Overall system description: The instruments must operate fully automatically in situ and include: 1) At least three acoustic Doppler current profilers (ADCPs) capable of obtaining ocean current profiles in 1m or smaller bins, at three sites ranging in depth from 3 to 20m; 2) At least two sensors and associated firmware/software upgrades to ADCPs, of sufficiently high sensitivity and sampling frequency to obtain hourly one-dimensional spectra of surface wave amplitude at two sites ranging in depth from 3 to 20m; 3) Batteries, housings, cabling, and other hardware necessary to allow unattended continuous deployment of instruments in the field for up to six months; 4) Trawl-resistant bottom mounts capable of housing at least two current profiler / wave pressure-sensor instruments in environments where both high-energy wave action and significant commercial and recreational use are likely during deployment; 5) Cabling, connector plugs, and other hardware, capable of allowing download of in situ measurement data in the field without retrieval to land. Parts: The following components should be used in production unless it can be unequivocally shown that alternate parts improve accuracy and robustness. ADCP: To provide robust profiles of ocean currents with depth, accurate to 1 cm/s or better. Hydrostatic pressure sensor: To provide accurate, robust, 1Hz or greater measurements of bottom pressure variability associated with surface waves in shallow water. Wave estimation software and firmware: To estimate surface wave energy vs. wave period from pressure sensor data, for storage and retrieval of wave spectrum. Bottom mounts: To provide stability and protection for scientific instruments in the field. Data cabling and wet-mate-able plugs: To allow retrieval of scientific data from instruments in the field during deployment, for verification and analysis. Battery packs, pressure casings, and power cabling: To power operation of scientific instruments underwater in the field, without other external power sources, for necessary deployment times, including swap-out for extended deployment.
