The U.S. National Oceanic and Atmospheric Administration (NOAA) Coral Reef Watch (CRW) program has developed a daily global 5-km product suite based on satellite observations to monitor thermal stress coral reefs. These products fulfill requests from reef managers researchers for higher resolution by taking advantage of new satellites, sensors algorithms. Improvements the over CRW’s heritage 50-km are derived from: (1) greater data density NOAA’s next-generation operational geo-polar blended...
The global coral bleaching event of 2014–2017 resulted from the latest in a series heat stress events that have increased intensity. We assessed global- and basin-scale variations sea surface temperature-based products for 1985–2017 to provide context how during compared with past 3 decades. Previously, undefined “Heat Stress Year” periods (used describe interannual variation stress) were identified Northern Southern Hemispheres, which peaks or shortly after boreal austral summers,...
The National Oceanic and Atmospheric Administration (NOAA) Coral Reef Watch (CRW) program has been providing resource managers, scientific researchers, other coral reef ecosystem stakeholders with bleaching heat stress products for more than 20 years. development of the CoralTemp sea surface temperature (SST) dataset allowed CRW to produce Bleaching Heat Stress product suite climatologies daily SST measurements from within same dataset, significantly improving data quality. Previously,...
Climate change and its impacts on coral reefs have reached unchartered territory.
Satellite monitoring of thermal stress on coral reefs has become an essential component reef management practice around the world. A recent development by U.S. National Oceanic and Atmospheric Administration’s Coral Reef Watch (NOAA CRW) program provides daily global at 5 km resolution—at or near scale most reefs. In this paper, we introduce two new products in CRW Decision Support System for management: Regional Virtual Stations, a regional synthesis conditions, Seven-day Sea Surface...
The National Oceanic and Atmospheric Administration’s Coral Reef Watch program developed operates several global satellite products to monitor bleaching-level heat stress. While these have a proven ability predict the onset of most mass coral bleaching events, they occasionally miss events; inaccurately severity some or report false alarms. These are based solely on temperature yet is known result from both light This study presents novel methodology (still under development), which combines...
The primary consequence of global warming for reefs is coral bleaching, often leading to extensive mortality. Although bleaching well-documented globally, the thermal stress and experienced by unique South Atlantic remain largely unknown due insufficient monitoring on both spatial temporal scales. Therefore, this work aimed reconstruct past episodes across reefs, assessed whether are becoming more intense, longer-lasting, frequent. We retrieved daily 5 km-resolution Degree Heating Week (DHW)...
The U.S. National Oceanic and Atmospheric Administration's (NOAA) Coral Reef Watch (CRW) operates a global Four-Month Bleaching Outlook system for shallow-water coral reefs in collaboration with NOAA's Centers Environmental Prediction (NCEP). Outlooks are generated by applying the algorithm used CRW's operational satellite bleaching heat stress monitoring, slight modifications, to sea surface temperature (SST) predictions from NCEP's Climate Forecast System Version 2 (CFSv2). Once week,...
<title>Abstract</title> Ocean warming is increasing the incidence, scale, and severity of global-scale coral bleaching mortality, culminating in third global event that occurred during record marine heatwaves 2014-2017. While local effects these events have been widely reported, implications remain unknown. Analysis 15,066 reef surveys 2014-2017 revealed 80% surveyed reefs experienced significant 35% mortality. The extent mortality was assessed by extrapolating results from using...
Over the past four decades, coral bleaching events have occurred with increasing frequency and severity, directly linked to ocean temperature due climate change. For latter half of that period, satellite monitoring by NOAA Coral Reef Watch in near real-time has provided invaluable insight into risk. Here, we describe a novel application those products develop basin-scale tools for tracking development extreme heat enable global events. Case studies historical (1982-2018) across three...
Remotely sensed ocean color data are useful for monitoring water quality in coastal environments. However, moderate resolution (hundreds of meters to a few kilometers) satellite underutilized these environments because frequent gaps from cloud cover and algorithm complexities shallow waters. Aggregating over larger space time scales is common method reduce generate more complete series, but potentially smooths out the small-scale, episodic changes that can have ecological influences. By...

Abstract Ecological forecasts are becoming increasingly valuable tools for conservation and management. However, there few examples of near‐real‐time forecasting systems that account the wide range ecological complexities. We developed a new coral disease system explores suite relationships their uncertainty investigates how forecast skill changes with shorter lead times. The Multi‐Factor Coral Disease Risk product introduced here uses combination marine environmental conditions to predict...

Coral reefs are one of the most diverse ecosystems on Earth and provide significant ecological, economic, societal benefits valued at approximately $9.8 trillion U.S. dollars per year. Since 1997, NOAA's Reef Watch (CRW) has used near real-time satellite monitoring to ecological nowcasting ocean heat stress that can cause mass coral bleaching. While this benefitted reef managers, scientists, other stakeholders, our users desired longer-range forecasts. In 2012, CRW launched its...
