Coral Reef Watch’s Daily Global 5km Satellite Coral Bleaching Heat Stress Monitoring Products Contribute to New Allen Coral Atlas Bleaching Layer

May 26, 2021

NOAA Coral Reef Watch (CRW)’s operational daily global 5km satellite coral bleaching heat stress products are being used by Arizona State University (ASU) and its partners to create a new Bleaching layer (currently in beta status) in the Allen Coral Atlas. The Bleaching layer, which is updated every two weeks, detects variations in coral reef brightness using high-resolution Planet Dove satellite visible-band imagery and an advanced algorithm, to indicate whether reefs are experiencing heat stress, such as that from marine heatwaves, and bleaching.

Satellite Ocean Color for Reef Turbidity

April 26, 2021

ESSIC/CISESS scientists Erick Geiger, Gang Liu, and Jacqueline De La Cour at NOAA Coral Reef Watch have a new article on satellite ocean color data published in the 13 April 2021 issue of Frontiers in Marine Science. The goal of their study was to determine how best to fill satellite data gaps from cloud cover and quality control exclusions in shallow water. They tested a combination of six spatial (horizontal scale below) and seven temporal scales (vertical scale below) for aggregating data from the VIIRS instrument at several coral reef locations in Maui, Hawai‘i and Puerto Rico and compared these with in situ measurements of water turbidity.
