National Coral Reef Monitoring Program: Shallow Water Conductivity-Temperature-Depth (CTD) Profiles for selected locations across Phoenix (Baker) and Line (Jarvis) Islands in the Pacific Remote Islands Marine National Monument and Wake Atoll from 2017-04-03 to 2017-04-22 (NCEI Accession 0226041)

Preview graphic

The data described here result from near-shore shallow water Conductivity-Temperature-Depth (CTD) casts conducted at select sites around the Pacific Remote Islands Marine National Monument and Wake Atoll 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 the PRIA and Wake Atoll in 2017. The CTD casts provide vertical profiles (30-m max depth, downcast only) of water column conductivity, temperature, and pressure (Sea-Bird Electronics, SBE19-plus), with calculated depth, salinity, and water density.

The CTD 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 Data Processing Software and the R package "oce".

Purpose	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, ecosystem-scale approach for assessing coral reef climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. 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 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 provides 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. NCRMP is funded by the CRCP and the NOAA Ocean Acidification Program (OAP), 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 Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) at NOAA Fisheries leads in-situ NCRMP climate monitoring in the U.S. Pacific Islands Region (formerly under the Pacific Reef Assessment and Monitoring Program [RAMP]). 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) associated ecological impacts on carbonate accretion rates, erosion, and benthic community structure. ESD scientists work closely with CRCP and partners during annual Pacific NCRMP missions to deploy oceanographic (subsurface temperature recorders) and ecological (calcification accretion units [CAUs] and bioerosion monitoring units [BMUs]) instruments at fixed sites in the Pacific Ocean and conduct CTD casts and water sampling to evaluate coral reef environments. The in-situ data and satellite-based observations are also used in modeling efforts. Innovative analysis techniques are used to develop products that provide scientists, managers, decision makers and the public a better understanding of a region's resources and how they are changing over time.
