STATEMENT OF WORK

November 8, 2018

1. BACKGROUND: NOAA’s research and survey ships comprise the largest fleet of federal research ships in the Nation. Ranging from large oceanographic research vessels capable of exploring the world’s deepest ocean, to smaller ships responsible for charting the shallow bays and inlets of the United States, the fleet supports a wide range of marine activities including fisheries research, nautical charting, and ocean and climate studies. In addition to its ships, the NOAA Small Boat Program manages a fleet of more than 400 small boats that perform various data collection missions for NOAA throughout the United States and its territories including hydrographic surveys, fishing, diving, scientific instrument deployment/recovery, water and air quality monitoring, law enforcement and marine mammal surveys. Vessels vary in size from a simple 10-ft. kayak to a complex 85-ft. research vessel. The majority of small boats fall within the range of 16-26 feet in length and operate in near-shore environments, but extended missions in deep water environments are common among the larger vessels.

The NOAA small boats included in this Statement of Work (SOW) are carried aboard the NOAA Ship Fairweather (S 220), commissioned in 1967, as survey assets. The ship is homeported in Ketchikan, Alaska and her primary mission is conducting hydrographic surveys in support of nautical charting.
