National Coral Reef Monitoring Program: Shallow water conductivity-temperature-depth (CTD) profiles for selected locations across the Hawaiian Archipelago

browse graphicPreview graphic
Near-shore shallow water Conductivity-Temperature-Depth (CTD) surveys provided in this collection were conducted at selected sites around the Hawaiian Archipelago as part of the ongoing National Coral Reef Monitoring Program (NCRMP). Shallow water CTD surveys provide vertical profiles of temperature, salinity, and turbidity providing indications for water masses and local sea water chemistry changes. These surveys 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 Rapid Ecological Assessments (REA) and towed-diver surveys, both of which are archived separately.

Shallow CTD casts are vertical profiles (max 30 meter depth, downcast only) of water column conductivity, temperature, and pressure (Sea-Bird Electronics, SBE19-plus; accuracy of 0.005 S m-1 in conductivity, 0.0002C in temperature, and 0.1% in pressure). A transmissometer (Wetlabs Inc; provides profiles of beam transmittance, related to turbidity) and a dissolved oxygen sensor (Sea-Bird Electronics, SBE43; accuracy of 2% of saturation) are also attached. Data are collected by lowering the CTD in a profiling mode from a small boat at a descent rate of approximately 0.5 to 0.75m s-1 to a maximum depth of 30m. Data processing is performed using Seabird Instrument's SeaSoft SBE Data Processing Software.

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.
