36761 NCRMP: CTD American Samoa Data Set Published / External 32955 American Samoa Project On Going 2016-12 2024-08 2024 The data described here result from near-shore shallow water Conductivity-Temperature-Depth (CTD) casts conducted at select sites around American Samoa as part of the ongoing National Coral Reef Monitoring Program (NCRMP). 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 American Samoa in 2015, 2018, and 2023. 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 2015 and 2018, RBR Concerto in 2023) 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 NOAA National Coral Reef Monitoring Program (NCRMP) details a long term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. 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. doi:10.7289/v5sj1hxf NOAA Theme Global Change Master Directory (GCMD) Data Center Keywords DOC/NOAA/NMFS/PIFSC/ESD > Ecosystem Sciences Division, Pacific Islands Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > REEF > CORAL REEF Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > OCEANS > SALINITY/DENSITY > CONDUCTIVITY Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > OCEANS > SALINITY/DENSITY > CONDUCTIVITY > CONDUCTIVITY PROFILES Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > OCEANS > SALINITY/DENSITY > OCEAN SALINITY Theme ISO 19115 Topic Category oceans Spatial Global Change Master Directory (GCMD) Location Keywords OCEAN > PACIFIC OCEAN > CENTRAL PACIFIC OCEAN > AMERICAN SAMOA Instrument Global Change Master Directory (GCMD) Instrument Keywords CTD > Conductivity, Temperature, Depth Theme CRCP Project 743 Theme CRCP Project National Coral Reef Monitoring Program Theme CoRIS Discovery Thesaurus Numeric Data Sets > Oceanography Theme CoRIS Theme Thesaurus EARTH SCIENCE > Biosphere > Aquatic Habitat > Reef Habitat Theme CoRIS Theme Thesaurus EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment Theme CoRIS Theme Thesaurus EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > In Situ Physical Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Ocean Pressure > Sea Level Pressure Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Ocean Temperature > Water Temperature Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Salinity/Density > Conductivity Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Salinity/Density > Density Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Salinity/Density > Salinity Theme NODC DATA TYPES THESAURUS CONDUCTIVITY Theme NODC DATA TYPES THESAURUS DEPTH - SENSOR Theme NODC DATA TYPES THESAURUS PRESSURE - WATER [HYDROSTATIC PRESSURE] Theme NODC DATA TYPES THESAURUS SALINITY Theme NODC DATA TYPES THESAURUS SIGMA-T Theme NODC DATA TYPES THESAURUS WATER TEMPERATURE Theme NODC OBSERVATION TYPES THESAURUS in situ Theme NODC OBSERVATION TYPES THESAURUS physical Theme NODC OBSERVATION TYPES THESAURUS profile Theme NODC PROJECT NAMES THESAURUS CORAL REEF STUDIES Theme NODC PROJECT NAMES THESAURUS Coral Reef Conservation Program Theme NODC PROJECT NAMES THESAURUS NODC Ocean Acidification Scientific Data Stewardship Theme NODC PROJECT NAMES THESAURUS National Coral Reef Monitoring Program Theme NODC PROJECT NAMES THESAURUS US DOC;

Protocol 1 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.
