NOAA CRED Shallow CTD Profiles 2011-2012 from the American Samoa and Pacific Reef and Assessment Monitoring Programs on NOAA Ship Hi'ialakai (NCEI Accession 0107470)

The Coral Reef Ecosystem Division of the Pacific Islands Fisheries Science Center, part of the National Marine Fisheries Service, National Oceanic and Atmospheric Administration (NOAA), conducted 126 shallow CTD profiling casts near Pacific islands, atolls and banks during 2 research cruises totalling seven cruise legs on NOAA Ship Hi'ialakai in 2011-2012. Cruise HI1101 consisted of 3 legs and occurred in March - May 2011 near Wake Atoll, Guam, the Northern Mariana Islands, and part of the Pacific Remote Islands Marine National Monument (PRIMNM) as part of the Pacific Reef and Assessment Monitoring Program (Pacific RAMP). Cruise HI1201 had 4 legs. It occurred during February - May 2012. Areas included PRIMNM as part of Pacific RAMP as well as islands within American Samoa as part of the American Samoa Reef and Assessment Monitoring Program (ASRAMP).

Shallow Conductivity-Temperature-Depth (CTD) casts are vertical profiles (max 30 meter depth, downcast only) of temperature, conductivity and pressure. Data are collected at select nearshore locations, both around islands or banks and within lagoons. Auxiliary sensors are sometimes used to measure additional oceanographic parameters such as fluorometry, beam transmission and dissolved oxygen.
