These surveys were conducted by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD; formerly the Coral Reef Ecosystem Division) during ESD-led NCRMP missions to the PRIA from 2014 to 2025. The CTD casts provide vertical profiles (30-m max depth, downcast only) of water column conductivity, temperature, pressure, with calculated depth, salinity, and water density. The CTD (Sea-Bird Electronics, SBE19-plus in 2014-2018, RBR Concerto in 2023, 2025) was deployed from a small boat using a hand line and held just under the surface for 1 minute to cycle water through the instrument and tubing. Afterward, data were collected by lowering the CTD in profiling mode at an even pace (descent rate ~0.5 to 0.75 meters per second) to a maximum depth of 30 m. Data processing was performed using Sea-Bird Scientific SBE or RBR Ruskin Data Processing Software and the R package "oce". CTD casts are conducted to characterize the spatial structure of the physical and chemical properties of the ocean environment influencing the living coral reef resources observed during NOAA National Coral Reef Monitoring Program (NCRMP) missions.

The NCRMP coordinates various NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA is able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis. NCRMP is a framework for conducting sustained observations of biological, climate, and socioeconomic indicators at 10 priority coral reefs across the U.S. and its territories. This integrated approach consolidates monitoring of coral reefs under a uniform method in the Pacific, Atlantic, Caribbean, and the Gulf of Mexico for the first time. NCRMP is funded by the Coral Reef Conservation Program (CRCP) and supported by NOAA Fisheries, NOAA National Centers for Coastal Ocean Science (NCCOS), NOAA's Atlantic Oceanographic & Meteorological Laboratory (AOML), NOAA Coral Reef Watch, and many other partners. The Ecosystem Sciences Division (ESD) at NOAA Fisheries is leading in-situ climate monitoring in the U.S. Pacific Islands Region. The climate component of NCRMP in the Pacific provides a comprehensive view of climate change impacts on coral reef ecosystems and helps identify areas of resilience and vulnerability. The key indicators used to identify and monitor climate-driven trends include 1) thermal stress caused by changes in sea temperature, 2) ocean acidification resulting from changes in carbonate chemistry, and 3) ecological impacts by collecting data on coral growth rates, erosion, and community structure to understand the impacts of thermal stress and ocean acidification on the ecosystem. Each year, ESD scientists work closely with CRCP and partners during Reef Assessment and Monitoring Program (RAMP) missions to collect data using moored oceanographic and ecological instruments stationed at fixed sites in the Pacific Ocean, and water samples collected by divers. The in-situ data and satellite-based observations are also used in modeling efforts. Innovative analysis techniques are used to develop products that give fellow scientists, managers, decision makers and the public a better understanding of a region's resources and how they are changing over time. false eng false Spreadsheet ESD_NCRMP_CTD_DataDictionary_PRIAs 2025-01-13 publication CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) PDF - Adobe Portable Document Format PDF - Adobe Portable Document Format PDF - Adobe Portable Document Format PDF - Adobe Portable Document Format PDF - Adobe Portable Document Format CSV - Comma Separated Values (Text) PDF - Adobe Portable Document Format CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact WWW:LINK-1.0-http--link NCEI Contact Information Information for contacts at NCEI. information distributor https://accession.nodc.noaa.gov/0162248 WWW:LINK-1.0-http--link ESD_NCRMP_CTD_2014_PRIA.csv Shallow CTD profiles collected across the Pacific Remote Island Areas (PRIAs; Wake) by the PIFSC Ecosystem Sciences Division during MARAMP 2014 (HA1401).

Missing values are indicated with a blank. Conceptual Consistency The same methods of data collection are used each time a CTD cast is conducted. Conductivity, temperature, pressure, depth, salinity, and density are included in the observation dataset. Following a 1 minute soak, CTDs are usually deployed 5-10 feet above the reef at depths ranging from 0-30 m at permanent monitoring sites established by the NOAA Fisheries, Ecosystem Sciences Division. A CTD is deployed from a small boat using a hand line: SBE 19plus SEACAT Profiler was used in 2014 and 2017 and a RBR Concerto3 was used in 2022 . The CTD is held just under the surface (~1m) for 1 minute to cycle water through the instrument and tubing. Afterwards, the CTD is lowered in profiling mode, at an even, hand-over-hand pace (descent rate ~0.5 to 0.75 meters per second) to a depth roughly 5-10 feet above the reef (maximum depth of 30m). Once the target depth is reached, the CTD is immediately pulled back on board. A GPS waypoint is taken at the beginning of the cast to mark the position and time. Barkley, Hannah C hannah.barkley@noaa.gov processor Raw profile data from the SBE19+ are downloaded from the CTD as .HEX and converted to .CNV using the manufacturer-provided instrument-specific configuration file in Sea-Bird Scientific SBE Data Processing Software. Raw profile data from the RBR Concerto3 are downloaded from the CTD as .RSK and converted to .CSV using the manufacturer-provided instrument-specific Ruskin Software. Profiles are then trimmed to downcast only, any erroneous data spikes are filtered out, the surface equilibration period is removed, and data are binned into 1-m depth bins in R using the package "oce". Processed profile data are then exported as .CSV files.
