REQ 145027-25-0074 - Seaguard - SON R1.docx

STATEMENT OF NEED

(145027-25-0074)

PURPOSE:

The NOAA EcoFOCI program at NOAA PMEL requires SeaGuard II current meters to collect long-term measurements of ocean currents, temperature, and oxygen at key mooring sites in the Bering and Chukchi Seas to support ecosystem monitoring and fisheries management.

BACKGROUND:

The EcoFOCI program at DOC – NOAA – PMEL seeks to acquire two Aanderaa SeaGuard II current meter instruments to upgrade NOAA’s long-term biophysical mooring arrays in the Northern Bering and Chukchi Seas. These moorings support NOAA’s only sustained biophysical time series in the region, with core sites active for over 30 years. The SeaGuard II provides high-resolution measurements of ocean currents, dissolved oxygen, and pressure—key parameters for monitoring ecosystem change in Alaska’s marine environments. These data are critical for maintaining NOAA’s scientific and operational capabilities that support U.S. economic interests, including the management of commercially valuable fisheries and protection of maritime resources. This effort supports federal mandates under the Magnuson-Stevens Fishery Conservation and Management Act (16 U.S.C. §§ 1801–1882), as well as initiatives to modernize infrastructure and streamline federal operations under Public Law No. 117-58 and Public Law No. 117-169. Investing in modern, cost-effective instrumentation like the SeaGuard II ensures the continuity and integrity of foundational data-sets that directly support sustainable fisheries, reduce long-term maintenance and operational costs, and advance American leadership in ocean science. Failure to replace outdated instruments threatens NOAA’s ability to support the billion-dollar commercial fishing industry in the Bering Sea and U.S. Arctic—jeopardizing regional food security and the economic vitality of Alaska and the US.
